New Phase 1b in tests/run-tests.fish: catches a bare C1-shadowed-command
call in a functions/*.fish body with no matching uses-shadow(name) or
self-limiting(name) in that function's own CLASSIFICATION header. This
is exactly the check discussed after the rm and cd audits -- runtime
auto-unwrapping isn't viable in fish (there's no hook finer than
shadowing itself, and rewriting behavior invisibly at runtime is its
own footgun); a static lint using the CLASSIFICATION tag as the
declared-intentional marker is. Scoped to functions/*.fish only: the
one-function-per-file convention there makes body extraction exact
with no block-depth parser needed.
Added a new self-limiting(name) tag to the schema for the case a bare
call is safe not because the caller did anything, but because the
shadow's own logic already neutralizes the override: rm's and mkdir's
flag checks (verified precisely -- rm falls back to command rm for any
flag except a bare -r/-R/--recursive alone, which still routes to
trash; mkdir falls back to command mkdir -p for any flag, no
exception), and grep/fgrep/egrep/dir/vdir/cat's own tty auto-detection
(--color=auto, and bat's default color behavior -- verified
byte-identical to stock cat when piped, since bat also auto-disables
highlighting on a non-terminal). Explicit and durable rather than a
silent lint exemption: if a shadow's bypass condition is ever
weakened, every self-limiting site is one grep away instead of
silently wrong.
Running the first draft of the lint surfaced three more real bugs,
none previously audited:
- config-help.fish's --man pager path checks `type -q less` (proving
it wants the real less binary specifically, for less-only -R/+N
flag syntax) then called it bare, routing through our own
$PAGER -> ov -> less -> more -> cat fallback chain instead -- which
could hand those less-specific flags to a completely different
program. Now command less.
- _fish_deps_install.fish and _fish_deps_update.fish's binary-upgrade
paths cp a freshly downloaded binary over an already-installed one
with no existence guard -- the update flow's target is guaranteed to
already exist. Our cp shadow forces -i unconditionally (a plain
alias, not flag-aware like rm's), so this would hang waiting on a
confirmation prompt in any non-interactive run. Now command cp.
Same two files' lazydocker install path piped curl output into bare
bash, invoking our shell-switch wrapper instead of a plain
subshell. Now command bash.
- agents-init.fish's AGENTS.md/CLAUDE.md relocation calls mv bare in
four places; each is already guarded by a preceding test -f check on
the destination, so the -i alias was unlikely to ever fire in
practice, but explicit command mv removes the reliance on that guard
entirely rather than leaving it as the only thing standing between a
file move and an unattended hang.
The remaining ~65 flagged call sites across ~24 files were reviewed
individually and tagged self-limiting(rm)/self-limiting(mkdir)
(verified flagged with -f/-rf or -p) and self-limiting(grep)/
self-limiting(cat) (verified piped, captured, or -q/-c; none display
color to a human), plus uses-shadow(ls) for two existence-check-only
calls (cffetch.fish, ffetch.fish) whose output is redirected to
/dev/null.
Records each documented function's manual category in its own header, so
Section 5 can later be generated from source instead of hand-maintained
alongside it. Values reproduce the current grouping in
docs/manual/05-functions/ exactly; no documentation changes meaning here.
Four functions are skipped because they have no header at all yet
(branch, fc, gitup, sudo-toggle); they get one in the merge that follows.
Replace all ad-hoc inline comments between license headers and function
declarations with consistent SYNOPSIS / DESCRIPTION / ARGUMENTS / RETURNS /
EXAMPLE blocks across all 99 project-owned functions/ files. No executable
logic, variable names, or exit codes were modified.
Completes Task #6 from AGENTS.md (Retroactive Function Documentation
Standardization).
- Add comprehensive `--description` flags to all fish functions for better `help` and `functions` output.
- Introduce and correct `--wraps` flags to ensure proper completions for aliased commands (e.g., `top` wrapping `btop`, `zellij`, `upgrade` wrapping `paru`).
- Prepend descriptive comments before function definitions for better source readability.
- Add standard copyright and SPDX license identifiers to shell scripts.
- Enhance script robustness by ensuring consistent terminal checks (Kitty, WezTerm) and graceful fallbacks in window/tab spawning functions (`spwin`, `tab`).
- Implement graceful fallbacks to basic core utilities when preferred modern alternatives are missing (e.g., `top` falling back to system `top` if `btop` is missing, `view` falling back to `less` or `cat` if `nvim` is unavailable).
- Improve overall code consistency across the `functions/` directory.
