My Emacs configuration https://git.cjennings.net/dotemacs/atom?h=main 2026-05-16T16:30:04+00:00 2026-05-16T16:30:04+00:00 Craig Jennings c@cjennings.net 2026-05-16T16:30:04+00:00 urn:sha1:244d4c56768fcc60bd1b23fe45df7a57c7b293ec Resolves PATH through file-truename before applying home-directory and read/write checks across the path-handling tools (git_status, git_log, git_diff, move_to_trash, read_text_file, update_text_file, write_text_file, list_directory_files, read_buffer, web_fetch). Without the resolve step, a symlink under HOME pointing outside HOME would pass the prefix check but the tool would act on the real target -- a symlink-escape. move_to_trash also tightens the trash-bin construction (treats empty file extensions correctly) and switches the "critical directories" list to truename-resolved canonical forms so a symlinked ~/.config can't be trashed via an aliased path. update_text_file fixes an off-by-one in the line-count derivation when the source content is empty. Each source change pairs with tests in tests/test-gptel-tools-*.el and tests/test-update-text-file.el covering the realpath escape paths, the empty-extension trash case, and the empty-content line- count edge. Combined coverage is now 100% across all ten gptel-tools source files: 516 / 516 executable lines, 217 tests. 2026-05-16T09:26:20+00:00 Craig Jennings c@cjennings.net 2026-05-16T09:26:20+00:00 urn:sha1:ceeae9b5e2625e23e6e3792d06a6c8122a36d18b Three read-only git context tools so gptel can see what's changed without me pasting `git status` / `git log` / `git diff` output into every chat turn. Builds the first batch from the ADOPT bucket in `docs/design/gptel-tools-shortlist.org`. Shape per tool: - `gptel-tools/git_status.el` — `git status --short --branch` for a directory inside a git working tree under HOME. Returns the porcelain output, or a "Clean working tree" marker when only the branch line is present. - `gptel-tools/git_log.el` — `git log --oneline -nN` with an optional `--since` filter. N defaults to 20, capped at 100; nil / non- integer / out-of-range N falls back to the default. - `gptel-tools/git_diff.el` — `git diff [REF1 [REF2]] [-- FILE]`. Output capped at ~500KB so a runaway diff can't blow up context; truncation is reported inline. Validation is uniform: path must resolve under HOME, must be a directory, must be inside a git working tree (verified via `git rev-parse --is-inside-work-tree`). Color is disabled via `-c color.ui=false` at the git level (`git status` doesn't accept `--no-color` directly). Tests run against real temp git repos created via `process-file`, not mocked — there's nothing in gptel-tools/git_*.el that's process-mockable in a meaningful way, and a real `git init` + a couple of commits is cheaper than building a fake. 31 tests total: 7 for git_status, 11 for git_log, 13 for git_diff. Wired into `cj/gptel-local-tool-features` so gptel exposes the three tools on next restart.
