Air-gapped source code examiner / codeexam_help.txt 159 lines txt Claude has written, under my direction, a Node.js program called CodeExam. It is a source-code analysis tool that has many command-line options, and a text-mode interactive mode supporting most of the same command-line options. Attached is a text file with the help for command-line mode. I now want to start turning this into an interactive GUI, and want Claude's help in laying out the screen, and implementing GUI code. One possibility is to use HTMX. Another is XMLUI. The current code is NOT in the project (any .py or .js code you see there is out of date). When you're ready, I will attach the latest tarball (code-exam-phase9i-callinventory_2.tar) in this chat (Claude doesn't permit putting .tar files into a project). The GUI would need a menu, including to build and load indexes (see the --build-index and --index path commands). Below that, I think there are three panes: left is for lists (such as what would be output from --list-files, --list-functions, --call-inventory, --most-called, --file-map, --hotspots, --discover-vocabulary, etc.); middle shows output from clicking in the lists; names of files, functions, classes, etc. shown in the middle pane would be clickable to display the clicked-on item, and would be right-clickable for a pop-up menu with options corresponding e.g. to --callees, --callers, etc.); the right pane would show diagrams (currently produced with --mermaid option) and/or AI analysis. The most important commands are --multisect-search, --multisect-analyze, --claim-search, and --claim-analyze. Multisect takes a semicolon-delimited list of terms to search for; and the Claim operations take the text of a patent claim or other English-language text, use an LLM (either --use-claude or a local GGUF model selected with --claim-model) to extract terms (tight and broad, with synonyms) from it, and then ask an LLM to analyze code (right now a single function) in the context of the patent claim and the extracted terms. I am not sure where these most-important commands fit into the GUI. Give me your initial thoughts, and let me know when you're ready for me to attach the tarball. Show more 8:44 AM Architected three-pane GUI layout for air-gapped code analysis tool Architected three-pane GUI layout for air-gapped code analysis tool This is a really interesting design challenge. Let me share my initial thoughts on the GUI architecture and layout, then we can refine once I have the source. Technology Choice Between HTMX and XMLUI, I'd lean toward a different option worth considering: Electron with a simple HTML/CSS/JS frontend, or more practically, just running an Express server locally and using the browser. Here's my reasoning: You already have a Node.js codebase, so the backend is ready — you just need to expose the existing functions as HTTP endpoints or IPC calls. HTMX is elegant for server-rendered HTML fragments and would work well for the list/content panes (click a function name → server returns rendered HTML fragment → swaps into the middle pane). It's lightweight and keeps complexity low. XMLUI is less mainstream and would add a learning curve without obvious payoff here. A full framework like React would be overkill for what is essentially a three-pane document browser with some forms. So Express + HTMX + vanilla JS for the interactive bits (Mermaid rendering, right-click menus) seems like a sweet spot. Lightweight, air-gap friendly (no CDN dependencies at runtime if you bundle the few JS files), and your existing CLI functions become route handlers almost directly.

I'd put them in a collapsible bottom panel (like a terminal panel in VS Code). The workflow is: paste or load claim text → configure (Claude vs. local model, temperature, vocab options) → run → results populate the left pane (matched functions) and right pane (analysis). The bottom panel stays visible so you can iterate on terms. Left pane tabs switch between different list views. Each tab remembers its scroll position and filter state. The filter box at top applies to whichever tab is active. Clicking an item in any list populates the middle pane. The list views map directly to your CLI commands: --list-files, --list-functions, --hotspots, --most-called, --call-inventory, --discover-vocabulary, --list-classes, --class-hotspots, --gaps, --entry-points, etc. Middle pane shows source code (from --extract or --show-file) with syntax highlighting. Function/class/file names within the displayed code are detected and made interactive. Left-click navigates (equivalent to --extract or --show-file). Right-click opens a context menu with: View callers, View callees, Call tree, Extract with --follow-calls, Analyze with LLM, Show funcstring, Structural dupe search. The middle pane supports tabs so you can have several files/functions open. Right pane tabs for: Mermaid diagram (rendered client-side from the text your tool already generates), LLM analysis output (markdown-rendered), and possibly a "search results" view for when you run --search or --regex and want to see contextual hits. Menu bar: Index: Build index (directory picker + extension config), Load index (path picker), Rebuild functions, Stats, Scan extensions Search: Literal, Regex, Fast, Files-search, Folders-search — each opens a small input dialog, results go to left pane Analysis: Claim search, Claim analyze, Multisect search, Multisect analyze, Function analyze, File analyze — these open/focus the bottom panel View: Toggle panes, adjust context lines, max results, dedup mode, full paths, exclude-tests toggle How the Most Important Commands Fit For multisect-search / multisect-analyze: The bottom panel has a text input for semicolon-delimited terms. A toggle switches between "search only" and "search + analyze." Results flow into the left pane as a ranked list of functions/files/folders; clicking one shows source in the middle pane and (if analyze mode) the LLM analysis in the right pane. For claim-search / claim-analyze: The bottom panel switches to a larger textarea (or file-load button) for claim text. Options dropdowns for model selection (Claude API vs. local GGUF path), temperature, --vocab-tight, --no-vocabulary, --mask-all, --show-prompt. Running it is a multi-step pipeline that your backend already orchestrates — the GUI just needs to show progress (term extraction → search → analysis) and stream results into the three panes. Extracted terms could display as editable chips/tags in the bottom panel so the user can refine before the search step. One Concern The air-gap requirement means you can't rely on CDN-hosted libraries. You'd need to bundle: Mermaid.js (for diagram rendering), a syntax highlighter (Prism or Highlight.js), and HTMX itself. All are small and easily vendored. Mermaid is the largest at ~2MB minified but it's a one-time inclusion. I'm ready for the tarball whenever you want to attach it. Once I can see the actual code structure — especially how the CLI commands are dispatched and what data structures they return — I can give much more specific advice on the Express route structure and how to wire HTMX partials to your existing functions. code-exam-phase9i-callinventory_2.tar tar This is excellent, and thank you for the initial layout. Note that the middle pane will not only show code, but also output from commands. That output will also be clickable. Maybe middle pane needs an upper and lower pane, because user will often want to look at e.g. output of --domain-fns or --discover-vocabulary, and at the same time something from clicking in that output. Note that the underlying code is still evolving. As an example, a feature not yet implemented will be the ability to load multiple indexes at the same time, and have analysis applied across them (e.g. --list-classes would list classes across 2 or 3 indexes), or compare them (e.g. running --struct-diff-all across 2 or 3 indexes). So the GUI will change, and needs to be flexible. I don't want planned features to become too difficult to implement because of GUI already in place. Show more 8:56 AM Recognized structured data accessibility and prepared revised design documentation Recognized structured data accessibility and prepared revised design documentation Now I have a thorough understanding of the codebase. Here are my updated thoughts, informed by the actual architecture: Key Architectural Observation Your code has a clean two-layer structure that's GUI-friendly: CodeSearchIndex methods (in core/) return structured data — arrays of objects with name, filepath, score, lines, etc. do*() command functions (in commands/) format and console.log that data. For the GUI, we bypass the do*() layer entirely and call CodeSearchIndex methods directly, getting back JSON we can render in any pane. The do*() functions remain for CLI/REPL use unchanged. This means zero refactoring of your existing code — the GUI is a new layer alongside commands/, not a replacement. Revised Layout: Agreed on Split Middle Pane Your instinct about the middle pane is right. Here's the refined layout: ┌───────────────────────────────────────────────────────────────────┐ │ [Index ▾] [View ▾] [Analysis ▾] │ Index: .spinellis (1,247 files) │ ├──────────────┬──────────────────────────┬─────────────────────────┤ │ LEFT │ MIDDLE-TOP │ RIGHT │ │ List/Nav │ Command Output │ Diagrams / Analysis │ │ │ │ │ │ ┌──────────┐ │ domain-fns output, │ ┌───────────────────┐ │ │ │Files │ │ vocabulary output, │ │Call Tree│File Map│ │ │ │Functions │ │ search results, │ │ (Mermaid SVG) │ │ │ │Hotspots │ │ callers/callees, │ │ │ │ │ │Classes │ │ call-inventory, │ │ │ │ │ │Vocab │ │ struct-diff-all, etc. │ │ │ │ │ │CallInv │ │ │ │ │ │ │ │Dupes │ │ Items are CLICKABLE │ │ │ │ │ └──────────┘ ├──────────────────────────┤ ├───────────────────┤ │ │ │ MIDDLE-BOTTOM │ │ LLM Analysis │ │ │ [filter___] │ Source code / file view │ │ │ │ │ │ (from clicking above │ │ Formatted markdown│ │ │ Sortable │ or in left pane) │ │ output from │ │ │ columns │ │ │ --analyze, │ │ │ │ Syntax highlighted, │ │ --claim-analyze │ │ │ │ line numbers optional │ │ │ │ ├──────────────┴──────────────────────────┴─────────────────────────┤ │ CLAIM / MULTISECT WORKSPACE [▴ collapse] │ │ ┌─────────────────────────────────────┐ ┌──────────────────────┐ │ │ │ Paste claim text or load @file... │ │ Mode: [Multisect ▾] │ │ │ │ │ │ Engine: [Claude ▾] │ │ │ │ │ │ ☑ vocab-tight │ │ │ └─────────────────────────────────────┘ │ ☐ mask-all │ │ │ Extracted terms: [encrypt][key][cipher] │ ☐ no-vocabulary │ │ │ (editable chips — remove/add before │ [Run Search] [Analyze]│ │ │ running search) └──────────────────────┘ │ └───────────────────────────────────────────────────────────────────┘ How the panes interact — a concrete workflow User clicks "Hotspots" tab in left pane → left pane shows ranked list (name, score, lines, calls). User clicks AuthenticatorBase::register in the list → middle-top shows the hotspot detail (callers count, callees, file path); middle-bottom shows the extracted source code with syntax highlighting. User right-clicks the function name anywhere → context menu: "Callers", "Callees", "Call Tree", "Analyze with LLM", "Show Funcstring", "Find Structural Dupes". Selecting "Call Tree" renders a Mermaid diagram in the right-top pane. Selecting "Analyze" sends to LLM and streams output into right-bottom pane. User pastes claim text into the bottom workspace, clicks "Analyze" → term extraction runs, extracted terms appear as editable chips, then search results populate the left pane (switching to a "Claim Results" tab), the best match's source appears in middle-bottom, and the LLM analysis streams into the right pane. Why split right pane too The diagram (call tree, file map) and the LLM analysis output are often wanted simultaneously — you want to see the call tree while reading the analysis that references those call relationships. Tabbing between them loses context. Technology Decision: Express + HTMX + Vanilla JS After seeing the code, I'm more confident about this stack: Why it fits: Your CodeSearchIndex is already a pure-data class. We add an src/server.js that creates an Express app, loads one (later multiple) CodeSearchIndex instances, and exposes routes like GET /api/hotspots?n=25&filter=auth that return JSON. HTMX handles the pane updates — clicking a function name triggers hx-get="/api/extract?func=AuthenticatorBase::register" which returns an HTML fragment that swaps into middle-bottom. For the Mermaid rendering and right-click context menus, we use a small amount of vanilla JS. Multi-index future-proofing: The server holds a Map keyed by index name. Every API route accepts an optional ?index=name parameter (defaulting to the active one). The left pane's tab bar can show "[.spinellis] [.alljoyn]" when multiple are loaded. Commands like --list-classes across indexes just iterate the map and merge results. This is trivial to add later without restructuring the GUI — you just add a "select indexes" UI in the menu bar and the API layer unions the results. What to bundle (air-gap): Mermaid.js (~2MB), Highlight.js or Prism (~200KB for relevant languages), HTMX (~14KB), and a tiny CSS framework (Pico CSS at 10KB, or just custom CSS). All vendored into a public/vendor/ directory. Express is the one npm dependency; it has no native modules and works fine offline. What the Server Layer Looks Like src/ server.js ← Express app, routes, index management server-routes/ api-search.js ← /api/search, /api/literal, /api/fast, /api/regex api-browse.js ← /api/extract, /api/list-files, /api/show-file, etc. api-callers.js ← /api/callers, /api/callees, /api/call-tree, etc. api-metrics.js ← /api/hotspots, /api/domain-fns, /api/vocabulary, etc. api-claim.js ← /api/claim-search, /api/claim-analyze (SSE for streaming) api-dedup.js ← /api/struct-dupes, /api/func-dupes, etc. public/ index.html ← Single page, HTMX-driven app.js ← Context menus, Mermaid rendering, claim workspace style.css vendor/ ← htmx.min.js, mermaid.min.js, highlight.min.js The route handlers are thin — they parse query params, call index.getHotspots() or index.multisectSearch(), and return either JSON (for the vanilla JS parts) or rendered HTML fragments (for HTMX swaps). The do*() functions in commands/ are untouched. One Important Question Before We Start Building Streaming for LLM operations. The claim-analyze pipeline takes real time (term extraction → search → LLM analysis). Currently analyze.js uses callbacks/promises that resolve when the full response arrives. For the GUI, we want Server-Sent Events (SSE) so the user sees the LLM analysis streaming in word-by-word in the right pane, and sees progress updates ("Step 2/4: Running TIGHT search...") as they happen. This means the /api/claim-analyze route would be an SSE endpoint. Is that acceptable, or do you want to keep it simple with full-response-then-render? I'm ready to start building. I'd suggest we begin with a skeleton: server.js with a few routes (stats, hotspots, extract), the HTML layout with the pane structure, and HTMX wiring for click-to-populate. That gets the bones working and we iterate from there. Want me to start on that? For its air-gapped target, local LLM will be only option; no Claude. Local LLM will be slow-ish. So user will need to see something happening while local LLM is working. But full-response-then-render would be simpler, and fine for now, so long as this doesn't later make visible progress difficult to implement. Your new layout looks a bit more portrait and landscape, which I like, but the target machines will be desktops, not tablets. Yes, please start with the skeleton. 9:06 AM Architected zero-dependency server skeleton with vanilla JavaScript interactivity layer Architected zero-dependency server skeleton with vanilla JavaScript interactivity layer Good call on full-response-then-render for now. I'll structure the API handlers to return promises, so swapping to SSE later is just changing the transport — the data flow stays the same. Let me build the skeleton with Node's built-in http module (zero npm dependencies, matching your existing philosophy) and a tiny HTMX-like fetch-and-swap layer. Architected zero-dependency web skeleton with Node's built-in HTTP module Architected zero-dependency web skeleton with Node's built-in HTTP module Now let me build the skeleton. I'll create the server using Node's built-in http module (zero npm dependencies), the HTML layout, styling, and client-side JS. Verified server syntax and directory structure integrity Verified server syntax and directory structure integrity Now let me verify the server loads correctly with the existing codebase: Identified correct method signatures and field names for vocabulary data Identified correct method signatures and field names for vocabulary data I need to fix the vocabulary API route — the method name and field names are different from what I guessed: Validated code integrity and prepared deliverables Validated code integrity and prepared deliverables Now let me copy all the new files to outputs so you can download them: Prepared concise skeleton overview for implementation Prepared concise skeleton overview for implementation Here's the skeleton — 5 files, ~2750 lines total, zero npm dependencies. To run it, place server.js in your src/ directory and the public/ folder alongside src/: code-exam/ src/ server.js ← new index.js ← existing CLI entry core/ commands/ public/ ← new index.html style.css app.js vendor/ package.json Then: node src/server.js --index-path .your_index Open http://127.0.0.1:3000/ in a browser. What works in this skeleton: Left pane tabs: Functions (sorted by size), Files, Hotspots, Classes, Vocabulary, Entry Points — each fetches from the API and renders a clickable list with filter box Clicking a function: extracts source into middle-bottom, shows callers + callees in middle-top, all function names in the output are themselves clickable (navigation) Right-click context menu on any function name: Extract, Callers, Callees, Call Tree (renders raw Mermaid text until you vendor mermaid.min.js), Analyze (placeholder) Bottom workspace: multisect search works — enter semicolon-separated terms, click Run, results appear with term chips Menu bar: Index > Statistics, Search > Literal Search Resizable split handles between top/bottom in middle and right panes What's intentionally stubbed: Build/Load Index dialogs (these need a file picker, which is a UX question — directory input? drag-and-drop?) LLM analysis (the /api/analyze route isn't wired yet — waiting to decide how the local GGUF model connection works in the server context) Mermaid rendering (needs the vendored JS file; falls back to raw text) Syntax highlighting (works without it, just monochrome) SSE streaming (architecture supports it — the API handlers return promises, so swapping jsonResponse to res.write('data: ...\n\n') on specific routes is straightforward) Multi-index (the IndexManager class already holds a Map — the UI just needs an index selector dropdown) Key architectural decision: the server calls CodeSearchIndex methods directly and returns JSON. The do*() command functions in commands/ are completely untouched. This means your CLI/REPL continues working exactly as before, and the GUI is a parallel presentation layer over the same data. Server JS Index Code · HTML Style Code · CSS App JS Readme Document · MD CodeExam_GUI_initial.jpg Worked first time, out of the box! 9:30 AM Validated successful GUI functionality against large real-world index Validated successful GUI functionality against large real-world index That's fantastic — and against a real 23,546-file index no less. The screenshot shows the full workflow working: filtered function list on the left ("yy"), yylex selected with its 52 callers in middle-top, the actual C source code in middle-bottom, and the right panes ready for diagrams and analysis. A few things I notice from the screenshot that we should address: Immediate polish items: The "Calls" (callees) section isn't visible in middle-top — it's there but the callers list is pushing it off-screen. We might want the callers/callees sections to be collapsible, or cap the callers display at ~10 with a "show all 52" expander. The left pane function list is dense and working well — the line-count + name + path layout reads clearly. The filter is responsive. The middle-bottom source view header shows the filepath and line count nicely. What would you like to tackle next? Some options in rough priority order: Right-click → Call Tree wiring (get Mermaid rendering working so the right-top pane shows actual diagrams) Callers/callees UX — collapsible sections, "show more" limits, and making the caller file paths clickable to show the calling context Search results in middle-top (literal, regex, fast search via the Search menu, with results clickable to show source) Multisect workspace refinement — the bottom bar is there but could use testing with your real indexes Build/Load Index dialogs in the menu Syntax highlighting (vendoring highlight.js) Or if there's something in the screenshot that bugs you or a workflow you want to try first, let me know. I'm going to be in transit for most of the rest of the day, so I may need to leave it here for now. One thing: can you suggest where to get mermaid.min.js to put in vendors. I downloaded a package from https://github.com/mermaid-js/mermaid/releases but mermaid.min.js didn't seem to be in there. 9:35 AM Identified CDN source for minified library file Identified CDN source for minified library file The GitHub releases give you the source. For the pre-built browser bundle, grab it directly from a CDN: Direct download URL: https://cdn.jsdelivr.net/npm/mermaid@11/dist/mermaid.min.js Just save that file as public/vendor/mermaid.min.js. Then add these two lines to index.html right before the ``` The `app.js` already checks for `typeof mermaid !== 'undefined'` and will use it automatically once it's present. Alternatively, if you want a specific version pinned (good for air-gap reproducibility): ``` https://cdn.jsdelivr.net/npm/mermaid@11.4.1/dist/mermaid.min.js It's about 2MB. Once vendored, no network needed at runtime. Safe travels — pick it up whenever you're ready. The skeleton will be here and we can iterate on whichever piece you want next. CodeExam_GUI_with_mermaid.jpg Looking real already... Okay, I'll get back to you later and we'll work through the 6 points, probably in your current order. 9:42 AM Acknowledged successful diagram visualization and planned continuation Acknowledged successful diagram visualization and planned continuation That call tree for yyparse looks great — the Mermaid dark theme integrates well with the rest of the UI. Enjoy the trip, and we'll pick up with the six items when you're back. code_exam_interactive_help.txt 103 lines txt One thing just occurred to me. Some (maybe many) users will want to type command lines, within the GUI. Basically like current --interactive mode. That could probably go in the lower-right pane, where an eventual chat feature would go (open-ended chat with the local LLM about the code; will probably need a RAG to implement this, and might initially do as /chat within the current interactive mode). Or maybe can avoid RAG which chunking etc. issues, and instead just grab from index to put into chatbot's context (shouldn't impact GUI either way). Don't do anything about this yet, but getting --interactive into the GUI will likely be a task pretty soon. I'm uploading the /help message currently displayed in interactive mode. Don't think it should impact anything, but just so you know about. It's pretty similar to the --cmdline options. 9:52 AM Acknowledged future GUI integration of interactive command-line interface Acknowledged future GUI integration of interactive command-line interface Good heads-up. This fits naturally into the architecture. A few quick notes for when we get there: Where it goes: Lower-right pane makes sense — it's a text-in/text-out interaction, distinct from the structured list/source/diagram content in the other panes. When the LLM /chat feature arrives, it's the same pane with the same input box, just a different backend handler. Implementation approach: The cleanest path is probably a thin server-side route (/api/interactive) that accepts a command string, runs it through essentially the same dispatch() function that interactive.js already has, captures the console output, and returns it as text. The existing withFileRedirect pattern in interactive.js already shows how to intercept console.log — we'd do the same thing but into a string buffer instead of a file. This means zero duplication of command parsing logic. What it means for current work: Nothing changes. The pane layout already has the right-bottom area. The API pattern is the same as everything else. And the /chat RAG feature you're thinking about — using the index's existing search/extract methods to gather context rather than a separate chunking/embedding pipeline — is exactly right. The index is the retrieval system; you'd just call multisectSearch or searchLiteral to find relevant code, getFunctionSource to extract it, and feed that into the LLM prompt. The index already does what RAG vector stores do, just with inverted-index and structural methods instead of embeddings. No impact on the current six items. I'll keep this in mind as we work through them. I've noodled around with it a little, and continue to be impressed with how quickly and how well this has come together. I see the little Expand in the lower right, and that multisect search works, and that you have a nice arrangement of options relating to search/analyze, local/Claude, vocab tight, masking, using vocab. Nice job! I do of course also have some comments/requests, to tackle before moving onto your 6 points (or which anticipate some of your 6 points). I'll number mine starting with 10 to avoid confusion: make the vertical column separators adjustable like the horizontal separators already are; left pane is too narrow for much of what goes there can you get load index working, so I don't have to quit, and re-run with a different --index-path? By default, newly loaded index should completely replace whatever this in memory for the previous index. But if you could add a [] checkbox to add rather than replace an index, so that 2+ indexes could be combined in memory, and all operations applied to the combination, that would be great (would mean having to add some kind of "ndx1!", "ndx12" prefix to all path/filename displays, so may be too much work right now. But loading a single index to replace existing one at least. one of the first call trees I tried was much too wide to read; can you add something to allow zoom-in, zoom-out on diagrams?; and/or a way to pop out full screen and pan/zoom within that? right now the left pane has a sort-of menu to select from a few list types: Functions, Files, Hotspots, etc. There are going to be a LOT of lists/operations like this. I think a better way to present is a expandable/collapsible list of lists/operations. There might be two dozen or so. When user starts app, they see a list of lists, then to actually get a specific list, they expand with '+'. They can have multiple lists open by clicking more '+'. They can simplify with '-'. Start with the ones you already have, and we can then add more, and put them in sensible order. right now clicking on things in the left pane often either does nothing (e.g. in Vocabulary, where it may be hard to know what to do, but also in Classes), or if e.g. right-click pop-up to get a call tree, there's an error function in top right mermaid pane that says e.g. "Function 'src/commands/metrics.js@doVocabulary' not found", even though right click on doVocabulary if it appears in the middle pane will bring up a nice mermaid diagram. Okay that's it for now. Again, terrific job!

Since these are interconnected changes, I'll rewrite all three files completely. The left pane will have collapsible sections for BROWSE (Functions, Files, Classes), METRICS (Hotspots, Entry Points, Domain Functions, Hot Folders, Gaps), VOCABULARY, DUPLICATES, and CALLERS, where each section can expand or collapse independently. For the call-tree bug, the issue is that the left pane passes filepath@name to the API, but it needs to extract just the function name for the lookup. Looking at the server route, I need to parse the FILE@FUNC format properly and split it so findFunctionMatches gets the function name and filepath separately. I should also handle vocab token clicks to trigger a search for that token. Writing the updated files...

Let me plan and implement them carefully. Let me trace the bug in #15 (call-tree from left pane): When user right-clicks a function in the left pane (e.g., hotspots list), the funcInfo has filepath and name onFunctionContext calls showContextMenu(e, funcInfo) handleContextAction('call-tree') builds funcSpec = target.filepath + '@' + target.name This gets sent to /api/call-tree?func=filepath@name Server route does index.findFunctionMatches(func) with the ENTIRE "filepath@name" string But findFunctionMatches expects just the function name with an optional fileHint as a separate parameter The fix is to split on @ in the server's call-tree route, just like the extract route does. I also need to update the load-index route to accept a POST request with the index path in the body so the server can load it. Now I'm going to implement all these changes across the four files, and reorganize the left pane accordion with sections for browsing (functions by size, files, classes) and metrics. Implementing the changes... Show more Done Good set of changes — all interconnected. Let me work through them systematically.

Actually looking at the code, callees is already using index.findCallees(func) which handles the FILE@FUNC via findFunctionMatches. But wait, findCallees takes (functionName, fileHint) as separate args. Let me check... Looking at the callees method signature: javascript findCallees(functionName, fileHint = null) { And the current route: javascript const callees = index.findCallees(func); If func is "filepath@name", findCallees will try to match "filepath@name" as a function name, which won't work. I should split it. Show less Fix callees route to parse FILE@FUNC server.js +17 -9 Good. Now I need to also add a /api/class-methods route so clicking a class shows its methods. Let me add that. Actually, looking at the listClasses return structure, it already has a methods array with method details. But the current route strips that out. Let me add a separate route for class detail. Done Now add a class-methods route so clicking a class shows its methods: Contemplated implementing vocabulary search functionality for files route Contemplated implementing vocabulary search functionality for files route Add class-methods route after list-classes server.js +42 -11 Now for the files-search route, let me also add that since vocab click should search: Done Add a files-search route (for vocab click → find files containing token): Orchestrated comprehensive UI overhaul addressing resizable panes and accordion navigation Orchestrated comprehensive UI overhaul addressing resizable panes and accordion navigation Add files-search route after search route server.js +40 -1 Wait, that will match "// --- Vocabulary ---" twice since there are two occurrences. Let me check... actually str_replace requires unique matches. Let me look at what happened. Actually, my replacement contains // --- Vocabulary --- at the end, so the first occurrence was replaced. The second one (the actual route header) should still be there. Let me verify by checking the file. Actually I think the issue is that the replacement string ends with // --- Vocabulary --- and there was already another // --- Vocabulary --- below. So str_replace would have matched the first one. Let me check. The original had: // --- Search (literal) --- ...search route... // --- Vocabulary --- ...vocabulary route... I replaced the first // --- Vocabulary --- with the files-search route plus // --- Vocabulary --- at the end. So now it should be: // --- Search (literal) --- ...search route... routes['/api/files-search'] = ... // --- Vocabulary --- ...vocabulary route... That should be correct. Let me verify. Show more Syntax check server Script Good. Now let me write the full new client-side files. This is a big rewrite of all three files. Let me carefully plan the accordion left-pane structure and all the other changes. Changes summary: Vertical column resizers - Add drag handles between left|middle and middle|right panes Load index dialog - Modal with path input, replace/add toggle Mermaid zoom/pan - Wrap SVGs in a zoomable container with zoom buttons + scroll-to-zoom Accordion left pane - Replace tabs with expandable/collapsible sections Fix clicking - Vocab → files-search, Classes → class methods, fix funcSpec for context menu Implement the complete rewrite - Building out all three HTML/CSS/JS files with these features integrated Writing the client files... Show more Done Now the big rewrite of the three client files. I'll do them one at a time: Acknowledged user feedback and catalogued feature requests for implementation Acknowledged user feedback and catalogued feature requests for implementation Updated HTML with accordion left pane, load-index dialog, zoom controls on diagram pane, vertical split handles index.html I need to use bash to remove the file first, or overwrite it. Remove files for rewrite Script Now let me create the files again. Due to the length of these files, I'll need to be efficient. Let me write them out. Updated HTML with accordion left pane, load-index dialog, zoom controls, vertical split handles, fullscreen diagram overlay index.html Now let me write the CSS. Key additions: accordion styling, column handles, modal styles, zoom viewport, fullscreen diagram. Updated CSS with accordion, column resizers, modals, zoom viewport, fullscreen diagram style.css Now the big one - app.js. I need to rewrite it with: Accordion-based left pane instead of tabs Column resizers Load index dialog Mermaid zoom/pan Fixed click handlers for vocab, classes Fixed context menu funcSpec Complete rewrite of app.js with accordion left pane, column resizers, load-index dialog, mermaid zoom/pan/fullscreen, fixed vocab/class clicking, fixed context menu funcSpec handling app.js Now let me verify everything is syntactically valid and the files are ready. Syntax check all files Script Good. Now let me also check if there's a duplicate // --- Vocabulary --- in server.js from my earlier edit: Check for duplicate headers Script There's a duplicate comment line but that's harmless - just a cosmetic issue. Let me clean it up. See the duplicate area The first "Vocabulary" comment is misplaced — it should say "Files search". Let me fix it. Fix misplaced comment server.js +3 -3 Now let me copy everything to outputs. Copy to outputs Script Good. Let me present the files. Presented 4 files Done. Let me summarize the changes. Done Here's what changed for all five items: #10 — Vertical column resizers. Drag handles between left|middle and middle|right panes. Drag left handle to widen the left pane; drag right handle to adjust middle vs. right. CSS class .col-handle with cursor: col-resize, JS in initColumnResizers(). #11 — Load Index. Menu → Index → Load Index opens a modal dialog. Enter the path to an index directory and click Load. By default it replaces the current index; check "Add to existing indexes" to combine. Server-side /api/load-index (POST) handles loading and returns the updated index list. On success, the left pane sections all collapse and clear their cached data, ready to re-expand against the new index. #12 — Diagram zoom/pan. The diagram pane header now has +, ⊙ (reset), − buttons plus a ⛶ fullscreen popout button. Mouse wheel over the diagram pane also zooms. The ⛶ button opens a near-fullscreen overlay where you can see wide call trees with room to scroll and zoom. The Mermaid SVG is wrapped in a .diagram-viewport div that gets CSS transform: scale(). #13 — Accordion left pane. The tabs are replaced with expandable/collapsible sections. On load, the user sees a compact list of section headers: Functions, Files, Classes, Hotspots, Entry Points, Domain Functions, Vocabulary. Click any header's ▸ to expand it and load data. Multiple sections can be open simultaneously. Each shows a count badge. The filter box applies to all currently-open sections. Adding new sections later is just a new
in the HTML plus a case in loadSectionData(). #14 — Fix clicking. Three fixes: Vocabulary: clicking a token now calls /api/files-search and shows files containing that token, sorted by hit count Classes: clicking a class name calls /api/class-methods and shows the class's methods in middle-top, each clickable to navigate Call tree from left pane: the server's /api/call-tree, /api/callers, /api/callees routes now all properly parse the FILE@FUNC format, splitting into function name and file hint before calling findFunctionMatches Server JS Index Code · HTML Style Code · CSS App JS Excellent. Vertical columns are now adjustable. Viewing mermaid call-tree good now, with pop-out. Left pane now has beginning of long list of accordion drop-downs. And clicking on Vocabulary and Classes now does something. In the case of Classes, and probably other things that will go into the left pane, clicking on an item (like a Class) should perhaps create a sub-accordion inside the left pane (for methods within a class, for example) rather than populating the top middle pane. Tell me if that's possible. Don't need to do it right now, just want to know how feasible. Load Index works. However, the checkbox to load new index with previous one, rather than replacing it, doesn't seem to work. The new index appears to replace the old one. Okay, that will be usual default behavior, so no biggie. One UI thing is that, if a new index is loaded to replace old one, it's confusing to have window panes left over from the old one. Clear completely? Loading very large indexes doesn't seem to work here, when they do work with the CLI version. I don't yet know if this is behavior of the new version generally, or only from within GUI. I'm testing with: C:\work\code_exam\Nodejs_port\code-exam>node src/server.js --index-path ..\..\.chromium Loading large literal index (streaming)... where .chromium holds: Directory of C:\work\code_exam\.chromium 02/20/2026 12:25 PM 33,350,202 function_index.json 02/20/2026 01:21 PM 47,615,687 func_hashes.json 02/18/2026 05:22 PM 2,883,779,604 inverted_index.json 02/18/2026 05:20 PM 5,322,042,817 literal_index.json 02/20/2026 08:50 PM 5,948,053 vocabulary.json and where it is successfully loaded both the PY and Node.js CLI versions. Nothing for you to do yet. Just typing in observations. Show less 6:04 PM Analyzed feasibility of nested accordions, investigated add-mode checkbox and large index loading issues Analyzed feasibility of nested accordions, investigated add-mode checkbox and large index loading issues Good observations all around. Let me address each: Sub-accordion for classes (and similar): Very feasible. The accordion sections are just nested divs — there's nothing preventing a second level. Clicking "Classes" expands the class list, then clicking a specific class like AuthenticatorBase would insert a nested accordion-section underneath it showing its methods, each themselves clickable to extract source. Same pattern would work for: a file showing its functions, a folder showing its files, a struct-dupe group showing its variants. The data model is already there (/api/class-methods returns the method list). It's purely a rendering change — instead of calling renderClassMethods into middle-top, we'd insert a child accordion into the left pane. I'll plan for this as a general pattern: any list item that has "children" can expand inline. Clear panes on index load: Yes, easy fix. When loading replaces, I should clear all six pane bodies (middle-top, middle-bottom, right-top, right-bottom) back to their placeholder state, not just the left-pane sections. I'll add that next round. Add mode: I suspect the issue is that both indexes resolve to the same path.basename() key in the Map, so the second overwrites the first. If your first index is .spinellis and second is .chromium, the names would differ and it should work. But if you're testing .code_search_index both times, they'd collide. I'll fix this with a dedup suffix. Worth testing with two distinctly-named index directories. Large index loading: The "Loading large literal index (streaming)..." message means the CodeSearchIndex constructor is running its synchronous streaming JSON parser on that 5.3GB literal_index.json. In CLI mode this blocks the main thread and that's fine. In the server, it also blocks — meaning the HTTP server can't respond to requests until it finishes, but it should still complete. Possible issues: Node's default heap limit (~4GB on 64-bit) may be exceeded by the combined in-memory data from a 5.3GB literal index. The CLI might succeed because it loads only that one thing, while the server has slightly more overhead. Try launching with node --max-old-space-size=8192 src/server.js --index-path ..\..\chromium and see if it gets further. If it's a timeout on the browser side, the server would eventually become responsive — just the initial page load would fail if you open it before loading completes. CodeExam_GUI_load_chromium_index.jpg So, the large .chromium index (195,136 files) does load into the GUI, if it is loaded from the command line as in my previous message. But not from Load Index... in the GUI. Any thought on next thing for you to work on? Either from among my observations, or from your earlier 6 points? 6:51 PM Weighed timeout issue against practical UX improvements strategically Weighed timeout issue against practical UX improvements strategically 195K files — impressive that it loads at all in the GUI! The Load Index timeout is because the synchronous JSON parsing blocks the Node event loop for minutes on that 5.3GB file, so the HTTP response never comes back before the browser gives up. The fix is to make loading async (return immediately, poll for completion), but that's a plumbing change. Command-line loading works fine as a workaround for now. My recommendation for next focus: the sub-accordion pattern plus clearing panes on reload — these are both high-impact UX improvements that affect every session, and the sub-accordion establishes the pattern you'll use for many future additions. Specifically: Clear all panes on index load/replace (5 minutes) Sub-accordion for classes → methods (sets the general pattern for nested expandable lists) Sub-accordion for files → functions in that file (same pattern, immediately useful) Fix Load Index for large indexes — return an immediate "loading…" response and poll, so at least it doesn't error out silently Versus my original 6 points, I'd say #1 (call tree) is done, #2 (callers UX with the 15-item cap) is done, and #6 (syntax highlighting) is cosmetic and can wait. The remaining original items — more search types (#3), multisect refinement (#4), and build-index (#5) — are all useful but less impactful than nailing the left-pane navigation pattern. Want me to go ahead with items 1–3 above (clear panes + sub-accordion for classes and files)? Yes, go ahead with those, and while working on the left pane, can you add more of the list types that are in the CLI cmdline. I can list for you if you want. 6:53 PM Inventoried CLI commands and architected expanded accordion sections Inventoried CLI commands and architected expanded accordion sections I can infer from the CLI help what's missing. Let me check what index methods are available for the additional list types, then build it all. Charted implementation strategy for accordion enhancements and CLI integration Charted implementation strategy for accordion enhancements and CLI integration Let me check the current state of all files first, then build everything in one pass. Examined dedup commands and explored additional index methods Examined dedup commands and explored additional index methods Now let me check what additional index methods are available for the new list types: Architected comprehensive UI expansion with new API routes and accordion sections Architected comprehensive UI expansion with new API routes and accordion sections Now I have a complete picture. Let me build everything. Here's the plan: New accordion sections: Hot Folders, Most Called, Class Hotspots, Gaps (dead code), Func Dupes, Near Dupes, Struct Dupes Sub-accordions: Classes → methods inline, Files → functions inline New API routes: /api/most-called, /api/class-hotspots, /api/gaps, /api/hot-folders, /api/func-dupes, /api/file-functions Fix: Clear all panes on index load/replace Orchestrated HTML accordion expansion with CLI command integration Orchestrated HTML accordion expansion with CLI command integration Now the HTML with all new accordion sections: Prepared CSS styling for group labels in interface Prepared CSS styling for group labels in interface Now the CSS with group labels and sub-accordion styling: Prepared comprehensive app.js update with expanded features Prepared comprehensive app.js update with expanded features Now the big one — complete app.js with sub-accordions, all new sections, and clear-on-load: Verified code syntax and prepared file delivery Verified code syntax and prepared file delivery Syntax parses clean (import errors expected since CodeSearchIndex isn't available here). Assessed request to expand left pane list types Assessed request to expand left pane list types Here's what's new in v3 (2,414 lines total, slightly smaller than v2 despite all the additions): 7 new accordion sections (grouped under labeled headers): Section API Route Data Source Hot Folders /api/hot-folders Aggregated from hotspots Most Called /api/most-called getCallCountsWithDefinitions() Class Hotspots /api/class-hotspots getClassHotspots() Gaps (Dead Code) /api/gaps Entry points filtered through dead-code heuristics Exact Dupes /api/func-dupes getFuncDupes() Near Dupes /api/near-dupes getNearDupes() Structural Dupes /api/struct-dupes getStructDupes() Sub-accordions — click-to-expand in left pane: Files → expand to show functions in that file (via /api/file-functions), double-click for full source Classes → expand to show methods inline, double-click for detail in middle-top Group labels in left pane: Browse / Metrics / Duplicates — organizes the 14 sections visually. Clear panes on index load — all 4 content panes reset to placeholder state when replacing an index. Dupe click → detail view — clicking a dupe group shows the file list in middle-top with clickable paths. Server JS App JS Index Code · HTML Style Code · CSS I'll check this out soon. In the meantime, something I noticed in the previous version UI, likely same in the new: Do multisect search for /tree.?layer/;compositor;render;blink ; upper middle pane replaced with "Running multisect search..."; that then replaced with results with search. As soon as I click on a search result, lower middle pane nicely filled with code corresponding to what I clicked on, and ... upper middle pane immediately goes blank. But I want to see the search results at the same time as I'm drilling down into one of them. 7:22 PM Diagnosed UI handler overwriting search results, devised dedicated source-only click handler Diagnosed UI handler overwriting search results, devised dedicated source-only click handler Good catch — onFunctionClick overwrites middle-top with callers/callees info, nuking your search results. The fix is to make search-result clicks only populate the source pane (middle-bottom), leaving your results untouched in middle-top. Two changes needed in app.js: 1. Add a source-only click handler: Architected parameter-based solution for distinguishing click handlers Architected parameter-based solution for distinguishing click handlers 2. Make wireClickables support a source-only mode, and use it for search/multisect results: Identified necessary code updates for clickable element handling Identified necessary code updates for clickable element handling 3. Wire multisect and search results to use source-only mode: Reconciled context menu behavior with user's desire to maintain search visibility Reconciled context menu behavior with user's desire to maintain search visibility The fix: clicking a search/multisect result now only populates the source pane (middle-bottom). Your search results in middle-top stay untouched. The right-click context menu still works as before — if you explicitly choose "Find Callers" or "Extract Source" from the context menu, it will use middle-top since that's a deliberate drill-down action. But the default left-click just shows the code. Can you send me revised app.js? 7:51 PM Thinking about reconstructing app.js without prior context or specifications Thinking about reconstructing app.js without prior context or specifications Here you go — same file with the three edits applied. App JS Nice how upper middle pane stays intact with Multisect results, so I can see the results in lower middle pane at the same time. When Multisect result is a file, can you make the filename clickable to show the entire file in lower pane? Click classes to see sub-accordion methods works well. Right-clicking on items in left pane to see call-tree generally works. But sometimes I get "Mermaid: Cannot set properties of undefined (setting 'order')" and a big bomb icon showing in the multisect workspace that says "Syntax error in text". Understandable if some things can't be diagrammed, but user should be told why, not presented with mermaid-level errors. Are we going to be able to support highlighting in code of search results? We've discussed syntax highlighting, and I know there's some package for that, but this is different, and I think more important: when user is looking at code because of some search (or some operation in left pane), the parts of the code that matched the search should be highlighted. Maybe in yellow to start; eventually, there might be different colors for the different terms in a multisect search or a claim search. Similarly, when showing a diagram, it would be good if the focus of the diagram were highlighted. For example, in call-tree foo, have mermaid render the "foo" node in yellow. Let me know if these comments/requests of mine are coming in too random an order, and if we instead need more of a plan. With Structural Dupes, the user should be shown the dupe structure, not the original code, or at least not only the original code, but also the bizarre-looking AST-based funcstr that's shown with /funcstring in interactive: doSearch (src/commands/search.js L173-194, 22 lines): Funcstring: _ _ _(_, _) { _ _ = _._(_._); if (_._) { const _ = _._._(); _ = _._(_ => _._()._(_)); } _ _ = _._(_. _, { _: _._ * 0, _: _._, }); _ = _(_, _); const _ = _._; _ = _._(0, _._); _(_, { _: _._, _: _._, _, _, _: _._ || null, }); } Similarly, under DUPLICATES, could you add the equivalent of /struct-diff-all, which produces commentary like: .CodeExam5 code-exam> /struct-diff-all Structural diff summaries for top 3 multi-variant groups: [1] doSearch (2 copies, 2 variants): 4 of 64 differ: search -> literal (x2), doSearch -> doLiteral, searchHybrid -> searchLiteral [2] _funcHashesPath (2 copies, 2 variants): 2 of 5 differ: _funcHashesPath -> _vocabularyPath, 'func_hashes.json' -> 'vocabulary.json' [3] escapeRegex (2 copies): all word-holes identical (comment/whitespace diff only) These aren't necessarily central functionality, but they're examples of how sometimes (often?) clicking on something in some context should produce different results than clicking on the same thing in a different context. (Umm, hope that made some sense.) If we get this right now at the beginning, it will go smoother later I think. Let me know if these comments/requests of mine are coming in too random an order, and if we instead need more of a plan to get GUI functioning as well as CLI. Show more 8:17 PM Prioritized feature requests and mapped implementation strategy Prioritized feature requests and mapped implementation strategy Your feedback isn't too random at all — it's converging on a real architectural principle: context-sensitive clicks. That's worth getting right now. Let me organize what you've raised, implement the actionable items, and flag what needs more discussion. Doing now: Multisect file results → clickable → show file in lower pane Mermaid errors → friendly message instead of raw crash Diagram root node → highlighted (yellow/accent) Search term highlighting in source code (yellow highlight for matches) Context-sensitive state tracking (store "what brought us here" so renderers know what to highlight) Needs API routes + discussion (next round): 6. Funcstring display for structural dupes 7. Struct-diff-all summary view Let me build 1–5: Examined multisect file-clicking functionality for implementation Examined multisect file-clicking functionality for implementation Now let me fix multisect results — make file-scope results clickable: Orchestrated highlighting constants and search result modifications for code display Orchestrated highlighting constants and search result modifications for code display Now add highlight colors and the highlighting function, right after the escHtml/shortPath helpers: Strategized implementation of search result highlighting across multiple interface components Strategized implementation of search result highlighting across multiple interface components Now modify renderSource and renderFileSource to apply highlighting: Orchestrated fixes for search highlighting, error handling, and context-aware display features Orchestrated fixes for search highlighting, error handling, and context-aware display features Now set highlight terms for literal search, and clear them for non-search clicks: Reconciled highlight behavior between search and navigation contexts Reconciled highlight behavior between search and navigation contexts Now clear highlights when clicking from left pane (full function click), but preserve them in source-only mode: Resolved Mermaid error handling and enhanced diagram visualization Resolved Mermaid error handling and enhanced diagram visualization Now fix the Mermaid rendering — friendly errors and root node highlighting: Prepared to refactor call-tree handler for improved diagram rendering Prepared to refactor call-tree handler for improved diagram rendering Now update the call-tree handler and fullscreen to pass the root name: Orchestrated search result highlighting and context-aware display functionality Orchestrated search result highlighting and context-aware display functionality Now let vocab clicks also set highlight terms: Identified menu file-search action requiring updates Identified menu file-search action requiring updates Also set highlights for the menu's "Files Containing…" action: Resolved to preserve search results when clicking file names in interface Resolved to preserve search results when clicking file names in interface Also make file-search results preserve middle-top (same pattern as multisect): Verified implementation logic and prepared output Verified implementation logic and prepared output Now verify syntax and copy: Synthesized user feedback on UI improvements and feature requests Synthesized user feedback on UI improvements and feature requests Here's what's in this update: 1. Multisect file results clickable — file-scope and folder-scope results now render as clickable links that show the file in the lower source pane. 2. Search term highlighting in source code — when you click a search/multisect result, the source code shows matching terms with colored background highlights. Each term in a multisect gets a distinct color (dark yellow, green, purple, blue, orange, cyan, magenta, olive). Regex terms from multisect (like /tree.?layer/) are matched as regex patterns. Highlights auto-clear when you click from the left pane (non-search context). 3. Mermaid error handling — instead of raw "Cannot set properties of undefined (setting 'order')" or "Syntax error in text" crashes, you get friendly messages like "Call tree too complex or contains cycles…" or "Diagram contains characters Mermaid cannot parse…" 4. Diagram root highlighting — the focus function in call-tree diagrams gets a gold border/dark-yellow fill so it stands out from the callees. 5. Context tracking — state.highlightTerms tracks what search brought the user here. It's set by literal search, multisect, vocab click, and files-search. Cleared on left-pane clicks. This is the foundation for the context-sensitive behavior you described. Next round (needs API routes): /api/funcstring — return normalized funcstring for a function (for structural dupe display) /api/struct-diff — return structural diff summary for a dupe group These are rendering the same data differently based on how the user got there — exactly your "context-sensitive clicks" principle App JS CodeExam_GUI_mermaid_bomb.jpg I've attached a screenshot. In addition to seeing that term coloring works, and seeing the left pane nicely populated, and other good changes you've made, see the Mermaid bomb at the bottom, and the presence of maybe a tiny graph that has been drawn down in the lower left. The red wording in upper right is better than what user saw there before, but the mermaid error below the claim/multisect workspace is bad. In the same screenshot note that two classes appear. The index here was built from recent CodeExam *.js source. As you know, one of the key classes is CodeSearchIndex. Yet it doesn't appear here. I can see the index knows about CodeSearchIndex.js including the line "export class CodeSearchIndex", yet this doesn't show up as a Class. This is not a GUI-only problem, it's also in the cmdline tool. But it's a relatively new problem, and something with Class detection may have got broken. This also suggests higher priority for the TODO item of using tree-sitter from the JS version of CodeExam, as it was used in the PY version of CodeExam. Showing this problem is in cmdline as well as in GUI: C:\work\code_exam\Nodejs_port\code-exam>node src\index.js --index-path .CE_JS2 --build-index .\**\*.js --skip-semantic ...

Let me tackle both. Mermaid bomb: Mermaid injects error SVGs into the document body, not into the container. Need to intercept that. Class detection: Let me look at how listClasses works to find the bug. Identified regex bug preventing export class detection and mermaid error suppression strategy Identified regex bug preventing export class detection and mermaid error suppression strategy Found both issues clearly. Class bug: Line 519 of CodeSearchIndex.js — the JS class pattern is ^\s*class\s+(\w+) but export class CodeSearchIndex starts with export. The function pattern (line 514) has (?:export\s+)? but the class pattern doesn't. One-character-level bug. Mermaid bomb: Mermaid injects error SVGs into the document body when render fails. Need to suppress that. Let me fix both: Identified and corrected accidental code merge error Identified and corrected accidental code merge error That ate the array boundary. Let me fix: Verified pattern fixes across languages and diagnosed class detection regression Verified pattern fixes across languages and diagnosed class detection regression Good.

Let me also sanitize the Mermaid text before rendering: Debugged Mermaid node ID conflicts and sanitization issues Debugged Mermaid node ID conflicts and sanitization issues Now verify everything and copy: Verified pattern matches and prepared file updates Verified pattern matches and prepared file updates All four class patterns match. Let me copy the updated files: Prepared to synthesize three distinct technical fixes Prepared to synthesize three distinct technical fixes Three files changed: CodeSearchIndex.js — class detection bug fix (line 519): Was: /^\s*class\s+(\w+)/ — misses export class, export default class Now: /^\s*(?:export\s+)?(?:default\s+)?class\s+(\w+)/ — catches all JS/TS class declarations You'll need to rebuild indexes to pick up the fix index.html — added suppressErrorRendering: true to mermaid config app.js — Mermaid bomb suppression: Sanitizes angle brackets, quotes in Mermaid node labels before render Catches failed renders and removes any stray SVG/error elements Mermaid injected into the document body Friendly error messages stay in the diagram pane where they belong The CodeSearchIndex.js file is the big one — that's src/core/CodeSearchIndex.js in your tree, not a GUI file. The same pattern at line 519 also covers TypeScript since .ts/.tsx use jsPatterns. App JS Index Code · HTML Codesearchindex JS I will check. It would be good to know when/how the export class bug appeared. Only a few days ago, code was introduced to handle far more subtle class-detection issues than this one, so it seems odd to see this simple error now. 1:41 AM Investigated timeline and origins of class detection bug Investigated timeline and origins of class detection bug The user is asking about the history of this bug - when it appeared and how. Let me search the project knowledge and past conversations to find when the class detection code was modified. Done Good question. Let me check the history. Traced bug origins through codebase history and design patterns Traced bug origins through codebase history and design patterns Relevant chats 1 result Converting Python exam code to Node.js The search results show clearly that the JS class pattern [/^\s*class\s+(\w+)/, 'class', 1] was present from the very beginning of the Node.js port - it was in the initial conversion from Python to Node.js. The bug has been there since day one. The key insight: the function pattern line 514 has (?:export\s+)? but the class pattern line 519 never did. It was simply an oversight in the original port. The Python version uses re.match(r'^\s*class\s+(\w+)') which works for Python because Python doesn't have export keyword. When porting to Node.js, the function patterns got export handling but the class pattern was copied more literally from the Python version. The recent improvements to class detection - the inference from :: prefixes, the Set-based lookups for faster filtering, and the macro class exclusions - none of that addressed the core regex issue. The export class gap existed all along but went undetected because the test indexes were predominantly C/C++ codebases where export doesn't appear. Show less Done The search results tell the full story. The export class bug didn't "appear" — it was there from the very beginning of the Node.js port. Looking at the initial conversion chat from Feb 20: javascript // Line 514 - function pattern: HAS export handling [/^\s*(?:export\s+)?(?:async\s+)?function\s+(\w+)/, 'function', 1], // Line 519 - class pattern: NEVER had export handling [/^\s*class\s+(\w+)/, 'class', 1], The function pattern got (?:export\s+)? during the port because the Python original has def which never needs export. When I ported the JS patterns, I added export-awareness to function but copied the class regex more literally from the Python version (where class Foo never has export prefix, so the Python pattern was fine). The reason it wasn't caught: all the heavy testing was on C/C++ indexes (Chromium, spinellis) where export class doesn't exist. The "far more subtle" class work from a few days ago — the :: inference, the Set-based lookup optimization, filtering 0-method macro "classes" like CC_EXPORT — was all in listClasses() pass 2/3 logic (lines 3056–3150), which never touched the base regex patterns in _getPatternsForExt(). So this was a day-one oversight in the port, hidden because the test indexes were C++ codebases. The moment you indexed JS source with export class, it surfaced. The fix is trivially correct and verified — it's the same (?:export\s+)? prefix the function pattern already had, plus (?:default\s+)? for export default class. Whew, that's better. And your explanation makes sense. I do still think this is an argument for moving to tree-sitter which was working well in the py code (apart from some versionitis issues). Presumably any index built with the JS version would now need to be rebuilt if the index contains JS or TS code? I hadn't commented before: yellow highlighting in mermaid call-tree looks good. Will it be possible (not now, soon) to handle clicks on function names that appear in a mermaid diagram? So far I'm not seeing the mermaid bomb, so that's good. I do see the "Call tree too complex or contains cycles that Mermaid cannot render. Try a simpler function or reduce depth" message when doing call-tree from an item in some parts of left pane like Vocabulary. Understood that some things in Vocabulary aren't functions and so don't have call trees. But think I'm still seeing instances where call-tree from left pane fails, but call-tree from middle pane succeeds. How simple or difficult to make code shown in lower middle pane clickable? Show less 2:09 AM Weighed feature requests and prioritized clickable source code implementation Weighed feature requests and prioritized clickable source code implementation Yes, any JS/TS indexes need rebuilding to pick up export class / export default class. C/C++/Python/Java/Go indexes are unaffected. On the other points: Clickable Mermaid nodes — very feasible. After Mermaid renders the SVG, we walk the SVG DOM, find the text nodes inside elements, and attach click handlers that call onFunctionClick. Will do soon. Call-tree left pane vs middle pane — I think the issue is that some left-pane items (vocabulary tokens, hot folders, most-called entries that are "external") don't have a filepath, so the funcSpec is a bare name that either matches nothing or matches multiple ambiguous definitions. Middle pane clickables carry data-filepath from the extract response, so they always have the resolved path. I should suppress the call-tree context menu option for non-function items, and improve the bare-name resolution. Clickable code in lower middle pane — this is the big one and I think very high value. The approach: after rendering source lines, scan each line for known function names (using the index's function list or inverted index), wrap matches in clickable spans. When clicked, same as clicking a function anywhere else — show its source, callers/callees. This makes the source pane a navigable code browser rather than just a display. Let me implement it now — it needs a new API route to resolve "is this token a known function": Deliberated clickable source code strategies, ultimately favoring simplest regex-based approach Deliberated clickable source code strategies, ultimately favoring simplest regex-based approach Find methods for resolving function names Script The approach for clickable source code: Server-side: Add an API route /api/known-functions that returns the set of known function names for the current index. This can be cached. Client-side: After rendering source, scan each line for function-call patterns (word followed by (), check against known functions set, wrap in clickable spans. Actually, sending ALL known function names to the client might be huge for large indexes. Better approach: When rendering source for a specific file, also send the list of functions that are called FROM that file (callees), plus any functions defined in that file. These are the ones most likely to be clickable. I could use a regex to find word( patterns and make them all clickable with a "try to resolve" approach where the click sends the name to the server. I'm weighing a few options here. I could add a /api/resolve-tokens route that takes a list of tokens and returns which ones are known functions, then call it once per source view. But honestly, the simplest approach is just to make any word( pattern clickable and let the click handler gracefully deal with unresolved names—no extra API call needed. I'll go with regex-matching function call patterns directly in the source. Show more Done The simplest approach that works well: regex-detect identifier( patterns in each source line and wrap them as clickable spans. The click uses the existing extract API — if the name resolves, show it; if not, it's a no-op. Zero new API routes needed. Deliberated on styling clickable source code links subtly Deliberated on styling clickable source code links subtly View current renderSource to plan the clickable code addition I need to: Add a function linkifyFunctionCalls(escapedHtml) that wraps identifier( patterns in clickable spans Apply it in renderSource and renderFileSource Wire up click handlers on those spans after rendering Need to be careful about order of operations: first escape HTML, then add highlights, then linkify. But linkify adds HTML tags that could interfere with highlighting. Better: linkify first, then highlight (since highlights wrap text inside existing tags). Actually, wait. The highlight function uses regex replace on the escaped HTML. If I linkify first (wrapping tokens in ...), then the highlight regex would try to match across the span tags and break. I'm realizing the cleanest solution is to handle linkification as a DOM post-processing step after rendering—walking the text nodes and wrapping function-call patterns directly, which sidesteps all the HTML string interference issues entirely. Implementing the linkify function now... Show more Check what SKIP_KEYWORDS exist in the index for reference Let me implement the clickable source code. I'll add a function that post-processes the rendered source DOM to make function-call patterns clickable.

Done Now add CSS for the clickable function links in source: Acknowledged index rebuilding necessity for JavaScript and TypeScript code Acknowledged index rebuilding necessity for JavaScript and TypeScript code Add CSS for clickable function names in source code style.css +5 -3 Now let me also think about the call-tree from left pane issue. The problem is likely that vocabulary items, hot-folder items, and most-called items don't all have proper filepath context. Let me check what happens when a vocabulary item is right-clicked. Looking at renderVocabList - vocab items have a click handler for onVocabClick but no contextmenu handler. So right-clicking wouldn't show a context menu... unless the user is right-clicking on items that DO have context menus (like hotspots, entry-points, etc.). Actually, looking at the code: renderFuncLikeList is used for hotspots, entry-points, domain-fns, gaps. These all have contextmenu handlers. The items should have filepath from the API, but the most-called items might be using def_files[0] which could be null, causing the context menu to fail. And vocabulary items don't even have context menus available - they're just clickable, so the user might be hitting that "Call tree too complex" error when trying to use call-tree from vocabulary items specifically. Looking at the different flows, the user could be right-clicking on various items in the left pane like hotspots or entry points where call-tree works, but some of those fail because the function names are too generic or have special characters. I should focus on getting the source code clicking working properly first and handle the syntax validation. Show more Verify syntax Script Let me also think about whether onFunctionClickSourceOnly is right here. When you click a function name in source code, it should: Show the function's source in the same lower pane (replacing current view) NOT touch the upper pane (preserving search results or whatever is there) That's exactly what onFunctionClickSourceOnly does. Good. But wait - when the user clicks a function in source and it navigates to that function's source, they lose their place. It would be nice to have breadcrumb/back navigation, but that's a future feature. Let me also verify: when onFunctionClickSourceOnly is called with filepath: null, will the extract API be able to resolve the function? It will pass just the bare name, and if there are multiple definitions, the API returns an ambiguous response. Actually, onFunctionClickSourceOnly handles that by calling renderDisambiguation when needed, which is acceptable since the user needs to choose. For unique function names it works seamlessly, and for common names like init or render, the disambiguation dialog appears—that's reasonable UX. Now let me copy the files. Show less Copy updated files Script Let me present the files but also give a good summary of what changed and what's coming. Presented 2 files And yes, rebuild indexes with JS/TS. The CodeSearchIndex.js fix was already delivered in the previous round. Done Two files changed (index.html unchanged from last round, CodeSearchIndex.js already delivered). Clickable source code — linkifySourceCalls() runs after each source render. It walks DOM text nodes in .line-content elements, finds identifier( patterns via TreeWalker, and wraps them in with click and right-click handlers. Skips language keywords (if, for, while, return, etc.), single-character names, and ALL_CAPS macros. Styled with a subtle dotted underline in dim accent color, brightens on hover. The click uses onFunctionClickSourceOnly — navigates to the clicked function's source in the same lower pane without disturbing whatever's in the upper pane. Right-click gives the full context menu (callers, callees, call-tree). If the name is ambiguous (multiple definitions), the disambiguation dialog appears in middle-top. This works because the DOM-walking approach avoids interfering with the tags from search-term highlighting — those are already in the DOM as elements, and TreeWalker only visits text nodes between them. On tree-sitter — agreed it's the right direction. The regex patterns work surprisingly well but every edge case (export class, template<>, EXPORT macros) is another patch. Tree-sitter gives you a real AST. The Python version proved it works. The main question is packaging for air-gapped Windows deployment — the Node.js tree-sitter bindings need native compilation. Worth a focused discussion. On the call-tree left-pane failures — I'll dig into this next. The suspicion is that some list items (especially from most-called, vocab) carry no filepath, so the bare function name either fails to resolve or hits ambiguity. The fix is to either suppress the call-tree context menu for items without filepath, or improve bare-name resolution in the API. App JS Style Code · CSS Clickable function names in middle pane look good. Your "If the name is ambiguous (multiple definitions), the disambiguation dialog appears in middle-top" makes sense, and I see it implemented, but could you try to have the code try to do the disambiguation? We already have disambiguation logic in handling of callees, and the commands that rely on it. Apply here too? A few places where a word inside quotes happens to match a function name, and that got made clickable. Like: console.log(`Warning: ${missing.length} files not found(first 5: ...') The word found in "not found" looks a bit silly, especially when clicking on it yields "Function 'found' not found". :-) Now that user is going to be navigating around the code by clicking funcname links, we're going to need a back and/or up arrow for them to return to where they were.

Auto-disambiguation — onFunctionClickSourceOnly now resolves ambiguous matches silently instead of showing the disambiguation dialog. Priority order: same file as currently viewed → same directory → largest definition (most likely to be the real implementation). Falls back to the dialog only if re-fetch still returns ambiguous. 2. Skip string literals — linkifySourceCalls now tracks quote context (', ", `) and ///# comment positions for each line. The "not found(" example will no longer produce a clickable "found". Also handles escaped quotes and template literals. 3. Back button — a ◀ button appears in the source pane header whenever there's history. Every navigation that replaces source content (function click, file click, source-only click) pushes the current state onto a stack (HTML, title, scroll position, filepath context). Clicking ◀ restores the previous view with scroll position preserved and re-wires the clickable function links. Stack holds up to 50 entries. Cleared on index reload. The back button appears only when there's somewhere to go back to — hidden when history is empty. App JS Index Code · HTML Style Code · CSS Back arrow in lower middle pane is good. So good it should also be available in upper middle pane (this would help with my earlier issue of user wanting to see multiple things at the same time, by making it easy to go back and forth -- though that means forward as well as back buttons). It does seem to be one level only though, and while we can't store infinite state, having a reasonable number of backs seems important. Also would like to be taken back to same line number I was at in the previous state. 2:45 AM Identified navigation gaps and devised multi-level history solution Identified navigation gaps and devised multi-level history solution The 50-level stack is already there in the code — if you're only getting one level, there's likely a bug where pushSourceHistory is saving the "Loading…" state instead of the real content.

Let me copy and deliver: Synthesized navigation enhancement requests across interface panes Synthesized navigation enhancement requests across interface panes Here's what changed: Generalized nav system (paneNav) — replaced the single-pane sourceHistory stack with a proper dual-pane back/forward system. Each pane (middle-top, middle-bottom) has independent back[] and forward[] stacks, 40 entries deep. ◀ ▶ buttons on both panes — small bordered arrow buttons appear/disappear based on stack state. Tooltips show depth count. Scroll position restored — navCapture saves body.scrollTop, navRestore restores it via requestAnimationFrame (waits for the DOM to paint before setting scroll, otherwise the browser ignores it on empty containers). Fixed the one-level-only bug — the root cause was navPush happening after showMiddleBottomLoading replaced the content with a loading spinner. The push would capture the loading div instead of the real content. Fix: embedded navPush at the start of each showMiddleTopLoading/showMiddleBottomLoading, before innerHTML replacement. This way every code path that replaces a pane automatically captures first — no more missed or double pushes. Forward stack — navigating back pushes current state onto forward. Any new navigation (not back/forward) clears the forward stack, matching standard browser behavior. Re-wiring on restore — middle-bottom restores linkifySourceCalls (clickable function names); middle-top restores wireClickables with sourceOnly: true so clicking from restored search results still only updates the source pane. App JS Index Code · HTML Style Code · CSS Perfect Perfect; "Show Funcstring" was good idea I see how you handled Struct Diff; looks right, but I need to look more carefully I don't see anything significant happening yet with Claim-Search, with either local LLM or Claude options. I also need the horizontal divider to be adjustable to make the workspace larger. If I try Show Prompt, I see a line or maybe a few lines rapidly appear in the upper middle pane, but they are cleared from screen with "No matches". I see 15 terms and "Extracted 15 keywords from claim", but it looks like you just extracted these directly from my text, rather than what the non-GUI version does, which is run the user's text through the LLM, to get the LLM to extract terms with synonyms, and tight/broad. If I do right-click Analyze (another good idea), I see prompt text, and the "Copy Prompt to Clipboard". Was your thinking that the user would Copy and then Paste into the workspace? That would be okay for initial testing, but isn't how the non-GUI version works. Good to see what the prompt looks like here. It says "Analyze this function with full context," but for analyzing of just a function, there isn't much other context we're providing I think? It's especially multisect-analyze and claim-analyze that have significant context. As noted at 4 above, right now "Show Prompt" isn't showing a prompt. This chat is getting long. After this round (assuming you've got fixes for 4 and 5 above), I'll want to switch to a new window, and will need to provide some context for the new instance of Claude. It will also need all the files. Trying to put tar or zip in the project isn't allowed. I could attach a zip to the chat prompt, but that's going to use a lot of tokens.
