Terax AI
“Workspaces with multiple git repositories are common, but most dev environments only recognize the workspace root, making it impossible to scope terminals, editors, and source-control views to a specific repository.”
01Co-authored nested repository targeting for a terminal-first AI-native development environment.
- Terax AI needed repository-aware source control for monorepos, submodules, and nested clones.
- Built a bounded lazy discovery system that recursively walks workspace directories, capped by depth, result count, and wall-clock time budgets.
- The original PR touched 55 files due to accumulated lint and type errors, causing the branch to drift too far from main.
- The maintainer stepped in, cleaned up the branch, and extracted only the feature delta for a clean merge.
- He co-authored me on the PR that merged the feature.
- Lesson: keeping a branch clean and close to main matters more than the number of commits.
“Editors that preview media inline are common, but browsers hardware-composite video and audio, so hiding the pane that contains them changes nothing — the controls keep playing over whatever sits behind them.”
02Fixed native media previews leaking over other tabs when the editor pane was backgrounded.
- Native video and audio controls in the editor leaked over other tabs whenever the pane holding them was backgrounded.
- WebKit hardware-composites media elements, so they ignore an ancestor's visibility — hiding the pane was not enough to hide the media.
- Passed the pane's visible state from the editor stack down to the pane, then hid and paused the media elements whenever it was not visible.
- Added a media preview kind helper, a regression test for visibility gating, and a test that the editor stack respects window inactivity.
- The maintainer contributed the commit that isolates media inactivity and pauses detached previews.
- Lesson: the bug was never in the editor's visibility logic — it was in the assumption that a hidden ancestor hides its media.
“Block command-bar path completion inserted file/folder names raw, so paths with spaces or shell syntax ($, &, *, quotes) split into multiple arguments or expanded in the shell. Copy Path also handed raw paths to the clipboard.”
03Complete quoted paths as literal shell arguments in block command-bar completion.
- Replaced raw insertion with shell-aware escaping: POSIX backslash escaping for macOS/Linux/WSL, PowerShell single-quoted literals on Windows (with '' doubling) while still supporting unquoting for completion.
- Moved escaping logic to a shared lib/shellQuote module used by both copy actions and block completion; added quote/escape-aware parsing to decode typed paths before filesystem lookup.
- Fixed tokenizer issues where escaped spaces were split and Windows quoted paths spanning separators weren’t unescaped correctly.
- Made completion workspace/shell-aware (respecting WSL vs native Windows) and hardened word extraction to handle quoted segments across separators.
- Added comprehensive tests (round-trips, real shell argument validation, PowerShell/cmd cases) and preserved raw clipboard payloads for editor/file-dialog use.
