Documents what each function needs for full functionality -- other repo functions it calls, and external CLI tools it uses or falls back gracefully without (e.g. rm/trash, ls/eza+lsd) -- matching the existing CLASSIFICATION convention's placement and the ~20 functions that already carried this label. Also broadens verify-manual.py's dependency-resolution check to recognize this repo's other existence-check idioms (command -q, command -v, which -- not just type -q) and dng2avif's dynamic type -q $cmd loop, since several genuine dependencies (eza, lsd, fastfetch, fd, ps, ...) are only ever guarded that way.

|
|
# SYNOPSIS
|
|
# cat [args...]
|
|
#
|
|
# DESCRIPTION
|
|
# Enhanced cat replacement. Wraps bat for files, giving syntax highlighting
|
|
# and line numbers; passes directories to ls; falls back to raw cat for
|
|
# ANSI-colored log files, and finally to /usr/bin/cat if bat is not
|
|
# installed.
|
|
#
|
|
# ARGUMENTS
|
|
# args... Files or directories to display
|
|
#
|
|
# EXAMPLE
|
|
# cat README.md
|
|
# cat ~/projects/myapp
|
|
function cat --wraps='bat' --description 'Use bat for files, ls for directories, and raw cat for ANSI logs'
|
|
# Opinionated guard (C1): fall back to bare command cat when disabled.
