Conditional abbreviations

[rbhanot4739]

Thank you for the amazing plugin, and it works really well. Just wondering if its possible to add certain abbreviations only if the command exists. For example, this is what I have in my aliases file

if [[ $(command -v eza) ]]; then
	alias ls='eza -I "*pyc*" $eza_params'
	alias lsa='ls --all'
        ...
fi

However, when I import these aliases into abbreviations, this logic isn't respected automatically (which is acceptable and not a big deal). So is it possible to add such if/else conditions in the $ABBR_USER_ABBREVIATIONS_FILE and have an abbreviation defined based on that ?

Interesting question!

Three solutions come to mind:

Put the condition in the abbreviated command itself (wrapping the if condition in {} prevents its exit code from affecting whether the else is reached).

% abbr ls='command -v eza && { eza -I "*pyc*" $eza_params } || ls'

Or use the standard command as a fallback (2>/dev/null prevents the "zsh: command not found" output from showing in your terminal)

% abbr ls='eza -I "*pyc*" $eza_params 2>/dev/null || ls'

Or conditionally add session abbreviations when the shell starts:

# .zshrc

# load zsh-abbr and then

if …; then
  abbr -S …
