Expand global abbreviation after colon?

[henrebotha]

Is this currently possible?

$ abbr add -g '@p'='$(pwd)'
$ docker run -v $(pwd):@p<space>
# expands immediately to:
# docker run -v $(pwd):$(pwd)

That is to say: Can things be configured such that global abbreviations get expanded after a colon (:)?

I assume it's not.

I think it's currently not.

The LBUFFER (command line to the left of the cursor) is split with ${(z)LBUFFER}. You probably know this, and I'm not at a computer and am not in zsh headspace so forgive mistakes, but you can check your input with something like

edit: fixed the mistake

input="a:b"; fragments=( ${(z)input} ); for fragment in $fragments; do echo $fragment; done

In the earliest early versions I attempted to roll my own splitter, which would split on whitespace and various non-letter characters. It gave me trouble.

Thinking about it now, if this were worth doing it might work to build on (z). Split with z, and then split the resulting items with the items in a user-configurable array. Lots of looping, don't know if it'd be performant.

I was poking around the code to see if I can spot where the relevant splitting comes into play, but no luck. But yeah it appears this successfully adds splitting on colons:

${(s.:.)${(z)input}}

Nice maybe that will teach me to wait until I'm more awake.

but no luck

https://github.com/olets/zsh-abbr/blob/main/zsh-abbr.zsh#L1577 should add support in expansion (this doesn't add support in the reminders system)

[olets]

More involved than that one spot. I like the idea of being able to customize this. Will work on a new config variable

I have to say, I enjoy how easy it is to send you into a little rabbit hole

Lollolll 😅

 

Released in 6.4.0

• It's written up in Characters which delimit abbreviations are user-configurable [#196. see also #9, #191, #195] #198

tl;dr

# .zshrc

# above where zsh-abbr is loaded
ABBR_SPLIT_FN() {
  REPLY=( ${(z)*//:/ } )
}

• Or combine with Expand inside quotes? #191

# .zshrc

# above where zsh-abbr is loaded
ABBR_SPLIT_FN() {
  REPLY=( ${(z)${*//:/ }//['"]/ } )
}

but don't miss the caveats in the full write up
