- Switch build profile to `panic = "unwind"` to allow catching panics in vendored uutils code.
- Add `run_caught` to wrap utility execution in `catch_unwind`, converting panics into non-zero exit codes.
- Update `pi-natives` to distinguish between recoverable utility panics and fatal process crashes, preventing recovered panics from appearing in user-facing crash reports.
- Propagated IO errors from the bounded tail internal logic to avoid panics.
- Updated `print_target_section` to return `io::Result` instead of unwrapping.
- Added a test case to verify that `BrokenPipe` is correctly surfaced when the consumer closes the pipe.
- Implement an argv-independent `format_usage` within `pi-uutils-ctx`.
- Update all vendor crates to import the function from the new location.
Fixes#3727
- Added a fallback mechanism to treat invalid regex patterns as literal search strings instead of aborting.
- Implemented a targeted recovery for unclosed or extra parentheses that attempts to escape only the problematic characters while preserving active regex syntax.
- Updated `pi-uu-grep` to perform pattern-specific fallback when multiple search strings are provided.
- Added regression tests to verify graceful degradation for invalid patterns alongside standard regex operation.
- Added a fallback mechanism that recovers from invalid regex patterns by treating them as literals instead of failing.
- Enabled this behavior by default, allowing valid regex alternatives to retain their functionality when mixed with invalid patterns.
- Updated the extended regex flag to enforce strict syntax parsing and return errors for invalid patterns.
- Added an `fd` command-line utility for searching the filesystem.
- Implemented file filtering capabilities for type, size, modification time, and ownership.
- Integrated directory traversal and ignore-pattern support for search optimization.
- Registered the builtin in the shell and added comprehensive integration tests for filtering and globbing.
- Implemented `rg` shell builtin using ripgrep libraries to enable file and directory searching.
- Added `RgSink` to handle output formatting, context, and vimgrep compatibility.
- Updated shell context and IO flags to support stdin as search input.
- Added integration tests for directory recursion, ignore filtering, and stdin handling.
- Added tree-sitter markdown support to resolve headings into full sections in `pi-ast`.
- Enabled block operations (`SWAP.BLK`, `DEL.BLK`, `INS.BLK.POST`) on markdown headings so they encompass the entire section, including nested deeper headings.
- Updated system prompt to guide agents in using structured markdown heading edits for plans.
- Fixed `plan-mode-guard` to correctly resolve local protocol options for subagents.
- Added support for `--quiet` (`-q`) and `--line-regexp` (`-x`) to the `grep` builtin.
- Enabled short-circuiting behavior for `-q` to suppress output and return early on the first match.
- Configured exit status logic to prioritize successful matches over error states when using `-q`.
- Added integration tests to verify correct exit status codes and line anchoring behavior.
- Ensure `-exec` commands run in the shell current working directory rather than the host process CWD.
- Update operand path resolution in `find` matchers to use the display path, matching behavior expected by shell-integrated utilities.
- Add an integration test to verify path substitution and execution context for shell-integrated `find`.
- Introduced `pi-uutils-ctx` to manage thread-local I/O redirection, environment context, and path resolution for in-process utilities.
- Integrated a suite of vendored coreutils (cat, find, grep, head, ls, mkdir, mv, rm, sort, tail, uniq, wc) as shell builtins.
- Added infrastructure for command cancellation, streaming I/O, and locale-aware error reporting within the shell environment.
- Configured shell-side dispatch logic to route commands through the new utility context, enhancing performance and binary integration.
Replace the compile-time cfg!(target_os = "macos") jamo-width heuristic
with a runtime override (process-global AtomicU8 in pi-natives, mirrored in
the TS width engine) plus terminal-identity detection: Ghostty renders
Hangul Compatibility Jamo (U+3131..U+318E) at 2 cells, so it is forced wide;
every other terminal keeps the platform default (macOS narrow, otherwise
UAX#11), making the override a no-op outside Ghostty.
Fixes doubled/ghosted jamo during Korean IME composition on Ghostty, where
the hardware cursor landed inside the typed text and the IME candidate window
drifted from the glyph. The width is resolved synchronously before the first
paint, so no stdin/CPR probe or async cache invalidation is needed.
A runtime DSR/CPR probe that auto-detects the width on unknown terminals is
tracked in a follow-up.
- Introduce `detach_reparent` parameter to command execution to support process reparenting.
- Add `detach_session_reparent` to Unix command extensions using a double-fork technique to orphan processes from the shell descendant tree.
- Update background pipeline logic to automatically apply reparenting when unwrapping transparent wrappers like `nohup`.
- Remove unused `command_is_resolvable` helper.
- Added `Shell.liveBackgroundJobCount` to query active background processes.
- Retained per-call `:async:` shells if background jobs are still running upon turn completion.
- Reaped shells automatically once their last background process exits to prevent lingering processes.
- Enabled Julia language support by adding a sub-syntax definition file.
- Integrated the new syntax into the highlighter by updating the syntax set builder.
- Configured the dependency to support YAML syntax loading via syntect feature flags.
- Updated `render`, `renderMany`, and native snapcompact methods to return promises, ensuring scalable async execution.
- Refactored `transformProviderContext` and `buildSideRequestContext` to support asynchronous operations in agent loops.
- Integrated `Promise.all` for improved concurrency when processing frame rendering and rendering batch operations.
- Updated all internal call sites, SDK hooks, and test suites to accommodate the asynchronous API signatures.
The parallel streaming walker accumulated match_count toward the
first-page stop budget, but match_count can exceed the matches actually
returned (collected) by one whenever a file overflows its per-file cap.
With the production config (max_count=2000, max_count_per_file=21) that
over-count could quit the walk a few percent short of the requested
page. Budget on collected instead, matching run_sequential_grep and
aggregate_parallel_results.
