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.
The non-git fallback used a substring match, so a negation line such as
!AGENTS/foo counted as the pattern AGENTS/ already being ignored and the
real rule was never appended.
CONTRIBUTING states doc-headers are written as plain text -- the header
is read as-is by config-help, by funcsave, and by anyone opening the
file, and docs/codespans.py adds the site's inline code spans at render
time. 22 files had drifted from that, carrying 41 hand-written spans
that reached config-help and the man page as literal backtick
characters inside an otherwise verbatim block.
The one span whose content ended in a space is requoted rather than
dropped, so "read> " keeps reading as a prompt string.
RETURNS previously conflated fish's $status exit code with genuine
stdout/printed output, e.g. rm listing "0/1" as if they were print
values rather than exit codes. Rename RETURNS to EXIT STATUS across
all 83 documented functions, and reintroduce RETURNS as a distinct
label reserved for the 15 functions that actually print to stdout.
Update build-manual.py's ENTRY_HEADS to render Exit Status before
Returns, manualtools.py's SECTIONS constant, and AGENTS.md's label
order and label-usage guidance to match. Add two verify-manual.py
regression tests: EXIT STATUS bodies must never contain stray
stdout/printed language, and Returns: must always render after
Exit Status: when both are present. Regenerate docs/fish-config.md.
- Strip leading / from pattern before git check-ignore so root-anchored
patterns like /AGENTS.md are checked as repo-relative paths (AGENTS.md)
and correctly match existing rules — fixes duplicates on every run
- Rework helper to accept multiple patterns and write them as a single
labeled block with project-style header/footer comment rather than
appending bare patterns one at a time
- Move gitignore calls out of per-plug loop in --plugins mode so all
three docs/ patterns are checked and written in one block
- Remove 5 duplicate bare entries left in .gitignore by the broken runs
