The @@ picker only listed files with no preview. It now lists both
files and directories via fd (matching _fzf_search_directory), and
shows a bat-highlighted or image-rendered preview through
_fzf_preview_file. Image previews use a kitty-graphics-protocol,
chafa, viu, timg fallback chain via the new _fzf_preview_image
helper, benefiting the Ctrl+F directory search and git-status
pickers as well since they share the same preview helper.
Binding the raw @@ chord made a lone @ an ambiguous prefix, so fish
(with fish_sequence_key_delay_ms unset) held every typed @ indefinitely
until a disambiguating keystroke arrived, breaking things like
`ssh user@host`. Binding the single @ key instead and checking whether
the current token is already a bare @ removes the ambiguity entirely:
plain @ always self-inserts instantly, and a second consecutive @
triggers the picker in place, with no forced delimiter before you can
keep typing. Vi's normal/visual modes are left unbound, matching their
existing (no-op) @ behavior.
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.
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).
Adds __fzf_inline_picker function and @@ keybinding (Emacs + all Vi
modes). Opens an fzf session and injects the selected item at the
cursor position in the current command line. Includes SYNOPSIS/
DESCRIPTION doc block per project conventions. Updates README with
new binding in the User Bindings table.
