Changelog

Every user-visible fix and feature in GhostMap is logged here with the reasoning behind it. This is the product changelog; the round-by-round internal log lives alongside the extension source.

Public history starts at 0.5.0, the first version stamp shipped outside the maintainers. Earlier work was internal stabilization and is summarized below.

0.5.0 - June 18, 2026​

The first version stamp after multiple rounds of stabilization. Marks GhostMap as feature-complete pre-1.0: the Ghost Tree, the Ghost Engine, the Ghost Index, anchors, diagnostics, and status badges all behave as documented.

Added​

  • Status badges in the Ghost Tree header: the panel title now shows [loading], [cached], [stale-cache], [skipped], [no items], or [discarded:...] so you can see exactly what the engine is doing without opening the console.
  • Snippet coverage widened to 20 language IDs: the gh / gw / gr / gl / gxl / gxr prefixes are now available in JavaScript, TypeScript, JSX, TSX, C, C++, C#, Java, Go, Rust, PHP, Kotlin, Swift, Scala, Groovy, Solidity, Python, Ruby, Elixir, and Shell. Snippet availability does not imply Ghost Tree symbol extraction support.

Fixed (round 6)​

  • C# constructors and var fields: K&R and Allman constructors now appear in the Ghost Tree. Class-level var fields are detected; local var inside method bodies remains suppressed.
  • PHP method recognition in large files: a day-1 regex asymmetry where public function foo() required publicfunction foo() to match was fixed. Whitespace is now consumed uniformly across all access modifiers.
  • Setloading restored: a previous round removed what looked like a redundant call; it wasn't. Stale-cached trees no longer appear as "complete" while a refresh is running.
  • Removed the background fingerprint validator: an earlier attempt used synchronous file I/O on the Extension Host main thread, causing 2 to 10 second freezes under RAM pressure. The optimistic-trust path plus the lazy mismatch detection remains.

Fixed (round 5)​

  • Live scanner references: parent class arrows were missing in 60k-line C# and Java files because the scanner mutated item ranges while callers held stale clones. The scanner now exposes live references.
  • Trailing comment backtrack: comments between two methods were being absorbed into the previous block's range. Fixed for Python, Ruby, Julia, and Elixir.
  • const and let arrow functions: const fetch = () => {} was invisible in JavaScript / TypeScript / TSX. Now extracted via a dedicated pattern.
  • Multi-line string state: PHP heredocs, JavaScript template literals, and Java text blocks are now tracked across lines. Braces inside strings no longer desync the frame stack.
  • Tab-switch race condition: a slow language server no longer pays the full 800 ms timeout after the user switches tabs. The wait polls every 50 ms and aborts immediately.
  • Cold-start fast path (Ghost Index): persisted snapshots now load as trusted on activate. First open of a known file paints in under 50 ms instead of 5 to 35 seconds.
  • LSP timeout reduced: 1500 ms to 800 ms, which halves the cold-LSP stall on first open.
  • Small-file fast path: files under 500 lines with an active language server skip Tree-sitter and regex entirely, saving up to 1.2 seconds of WASM load.
  • Tiny file bypass: files under 50 lines skip the 200 ms tab-spam backpressure window.
  • Lazy LSP warm-up: GhostMap pre-warms the active language server on activate, then staggers warm-ups for other visible editors after 2 seconds of idle.

Fixed (round 4)​

  • Allman brace support for C#, Java, C++, C, and Go: methods with the opening brace on a separate line now nest correctly.
  • Multi-line method signatures for TypeScript and Java: methods with arguments spread across multiple lines are detected.
  • Indent-based language nesting for Python, Ruby, Julia, and Elixir: a dedicated indent-stack tracker now produces nested trees instead of flat lists.
  • Pending body FIFO queue: two declarations queued before a { no longer overwrite each other.
  • Anonymous frame guard: object-literal methods are no longer treated as anchors.

Tests​

  • 166 passing unit and matrix tests, 6 passing smoke scripts.
  • Compile clean.

Pre-0.5.0: v1-coalesce-publish series​

  • Publish coalescer: 87% fewer TreeView event fires during a 60k-line progressive scan.
  • Progressive scanner: regex-based scanner for large files, batch-yielding via setImmediate to keep the editor responsive. C++ 60k scan: from ~19.5 s to ~33 ms.
  • Resumable scan: mid-scan tab switches no longer discard minutes of partial work.
  • SHA-256 cache fast path: tab switch to a warm-cached file skips fingerprinting entirely.
  • Local state persistence: the .ghostmap/ghostmap.json snapshot file was introduced.

Pre-V1 baseline​

  • Initial GhostMap activation, Ghost Tree view, and @ghost parser.
  • Safety-layer hardening: single-lane foreground, tab-spam backpressure, watchdog scheduling.
