Evaluate subshells in EXPANSION

[yutkat]

I'd like to define abbr as follows. abbr add --quiet -g gr='$(git rev-parse --show-cdup)'

ref: https://github.com/momo-lab/zsh-abbrev-alias#help -e, --eval evaluates subshells on expansion.

Thanks for the idea! At this time I'm not comfortable supporting evaluation in that way. Seems like a vector for easy abuse.

If you just need the result, you can use the default expand-and-accept behavior

abbr -g gr="git rev-parse --show-cdup"
gr

If you need to use the result in a command and don't care about seeing the full text of the command, that's a good use case for an alias

% alias -g gr="git rev-parse --show-cdup"
% cd my-repo/dir
% gr
../
% cat $(gr)README.md
# snip
% cd $(gr)

I see the limitation if you do want to see the full command and it needs to not be followed by a space, for example in the above cat $(git rev-parse --show-cdup)README.md example. Currently you can

abbr -g gr='$(git rev-parse --show-cdup)'
gr<Space><Delete>README.md<Enter>

which is okay but it'd be nice to document a way of expanding in place, without having to delete a space:

abbr -g gr='$(git rev-parse --show-cdup)'
gr<some binding>README.md<Enter>

I'll plan on adding that feature.

p.s. nice GH landing page!

I'll try to workaround it for now.

Thank you for your reply :wink:

Added some friendlier widget names, see https://github.com/olets/zsh-abbr#bindings

Closing but let me know if that doesn't meet your needs
