C1 shadows (rm, cat, ls, less, du, bash, top, ping, ssh, rg, mkdir, help) fall back to the bare command when __fish_config_op_aliases is falsy; rm falls back to exact 'command rm' with no wrapper. C2 gates the auto-venv PWD hook. C3 gates smart_exit (composing with Task #4 logging), fish_right_prompt, and all six expand_bang_*/expand_typo_sub functions atomically with the bang-bang system. C4 integration commands (spwin, tab, split, hist, logs, upgrade) refuse with a colored stderr error when disabled. config.fish now also strips the CachyOS distro config's own bang-bang bindings, history override, and alias opinions per category, restoring fish stock functions where they exist.

# SYNOPSIS
|
|
# __auto_source_fallback_venv
|
|
#
|
|
# DESCRIPTION
|
|
# Event handler that auto-activates a .venv Python virtual environment when
|
|
# entering a directory. Deactivates when leaving the project tree. Skipped
|
|
# when direnv is already managing the directory.
|
|
#
|
|
# EXAMPLE
|
|
# # Triggered automatically on directory change; not called directly.
|
|
# cd ~/myproject # activates .venv if present
|
|
function __auto_source_fallback_venv --on-variable PWD
|
|
status --is-command-substitution; and return
|
|
|
|
# Opinionated guard (C2): no automatic venv activation when disabled.
|
|
__fish_config_op_enabled __fish_config_op_autoexec; or return
|
|
|
|
# 1. Skip if direnv is already managing this directory
|
|
if set -q DIRENV_DIR; or test -e ".envrc"
|
|
return
|
|
end
|
|
|
|
# 2. If we are already in a venv, check if we've left its tree
|
|
if set -q VIRTUAL_ENV
|
|
# Check if the current PWD is still within the directory that owns the venv
|
|
# (Assuming the venv is at the root of the project)
|
|
set -l venv_root (string replace -r '/.venv$' '' $VIRTUAL_ENV)
|
|
if not string match -q "$venv_root*" "$PWD"
|
|
type -q deactivate; and deactivate
|
|
end
|
|
return
|
|
end
|
|
|
|
# 3. Only source the venv if we aren't already in one
|
|
if test -e ".venv/bin/activate.fish"
|
|
source .venv/bin/activate.fish
