- Added checks to filter out Kitty release events (event_type 3) in both matches_key_inner and parse_key_inner functions. Added comprehensive tests for both key matching and input handling to verify release events are ignored while press and repeat events are still processed correctly.
Fixes#325
- Removed sysinfo, bstr, and heapless dependencies from pi-natives. Removed transitive dependencies from Cargo.lock including byteorder, hash32, ntapi, objc2-io-kit, and windows 0.62.2.
- Added language module with 39 supported languages and tree-sitter parser bindings for ast-grep integration.
- Exported dedupeParseErrors utility function to remove duplicate parse error messages in tool output.
- Fixed duplicate parse error messages when multiple patterns fail on the same file.
- Replaced language alias lookup with O(1) phf::Map and added 30+ new language aliases (golang, julia, toml, zig, etc.).
- Migrated from ast-grep-language to direct tree-sitter language dependencies for improved language support.
- Converted clipboard copy operation from async to synchronous execution across native and TypeScript layers.
- Simplified copy_to_clipboard return type from task::Async<()> to Result<()> in Rust implementation.
- Removed promise chains and async/await from clipboard handlers in command and input controllers.
- Updated clipboard module documentation to explain synchronous execution avoids AppKit pasteboard warnings.
- Reordered fix:rs script to run cargo fmt before cargo clippy for consistent formatting.
- Fixed resource refresh tracking by storing connection references alongside promises to prevent stale deduplication.
- Fixed update target resolution to explicitly handle missing ompPath and use path.resolve() for consistent normalization.
- Added error handling and logging in Smithery registry detail fetching to gracefully handle failures and track issues.
- Fixed virtualization context cleanup in error paths to prevent partially-started instances from remaining active.
- Fixed API key retrieval to use dynamic provider configuration instead of hardcoded provider string.
- Enhanced test utilities to capture and verify request parameters for improved test coverage and debugging.
- Enforced tool decision in plan mode--agent now requires calling either `ask` or `exit_plan_mode` when a turn ends without a required tool call.
- Fixed cancellation behavior of `ask` tool to abort the current turn instead of returning a normal cancelled selection, while timeout-driven auto-cancel still returns without aborting.
- Added plan-mode-tool-decision-reminder system prompt to guide agent when required tools are not called.
- Improved agent_end event handling to use fallback assistant message when #lastAssistantMessage is unavailable.
- Fixed strikethrough reset logic to properly handle combined underline and strike attributes without resetting colors.
- Refactored write_line_end_reset to emit correct ANSI codes (24m for underline, 29m for strike) when both attributes are present.
- Added test case verifying strikethrough resets at line wraps while preserving foreground and background colors.
- Added TypeScript test case for strikethrough styling behavior across wrapped lines.
Remove the non-empty validation on `out` in both the TypeScript tool
layer and the Rust native layer. An empty replacement template now
deletes the matched AST node, which is the natural semantics.
Also remove .trim() calls on pattern and rewrite strings — trimming
silently destroys intentional whitespace and serves no purpose since
ast-grep matches on AST structure, not raw text.
BREAKING CHANGE: ast_find parameter 'pattern' (string) is replaced by
'patterns' (string[]). ast_replace parameters 'pattern' + 'rewrite' are
replaced by 'ops: Array<{ pat: string; out: string }>'.
Native (pi-natives / crates/pi-natives):
- astFind accepts patterns[] array; all patterns run per file, results
merged and sorted by path/line/column before offset+limit are applied
- astReplace accepts rewrites Record<string,string>; all patterns compiled
once upfront and applied per file in a single pass
- Deterministic result ordering via BTreeSet/BTreeMap
Coding-agent tools:
- ast_find: multi-pattern deduplication, '>>' prefix on match-start lines,
padded line numbers, directory-tree grouping (# dir / ## └─ file headers),
scopePath/files/fileMatches in tool details
- ast_replace: ops[] interface with duplicate-pattern rejection, diff-style
(-before/+after) previews grouped by directory, parse errors shown on
zero-replacement path, fileReplacements in tool details
- Tool prompts updated to document new interfaces with multi-pattern examples
- Task item id maxLength raised from 32 to 48 characters
- Added ast_replace tool test suite
Rust (crates/pi-natives/src/ast.rs):
- Expand supported languages from 7 to all 25 ast-grep tree-sitter
languages: Bash, C, C++, C#, CSS, Elixir, Go, Haskell, HCL, HTML,
Java, JavaScript, JSON, Kotlin, Lua, Nix, PHP, Python, Ruby, Rust,
Scala, Solidity, Swift, TSX, TypeScript, YAML.
- Pre-filter file candidates by language-resolvable extension before
reading or parsing. Non-code files (.md, .zip, .bin, .gitignore, etc.)
are silently skipped instead of producing misleading parse errors.
- Make canonical_lang_name exhaustive over SupportLang so the compiler
flags new variants on upstream upgrades.
TypeScript (ast-find.ts, ast-replace.ts):
- Format match output with hashline tags (LINE#HASH:content) when
hashline mode is active, consistent with read/grep tool output.
Falls back to plain line numbers when hashline mode is off.
- ast_find now emits all lines of a multiline match instead of a
single truncated preview line.

to the system prompt.
- Add examples and scoping guidance to ast-find.md and ast-replace.md.

- Improved LSP client message writing by simplifying header encoding and refactoring abort signal handling with the untilAborted utility.
- Enhanced native addon installation script to dynamically fetch release tags from GitHub API instead of using hardcoded versions.

Patterns like `\${platform}` or `a{b}` contain braces the regex engine
rejects as malformed repetitions. The new sanitize_braces() preprocessor
escapes { and } that do not form valid quantifiers ({N}, {N,}, {N,M})
before compiling, making grep resilient to literal template strings.
