Implement Kakoune's `A-S`
In Kakoune, it selects the first and last characters of each selection.
Where [] denotes a selection, [helix] becomes [h]eli[x]
It would look similar to https://github.com/helix-editor/helix/blob/87a720c3a13ccc7245f5b0befc008db5bd039032/helix-term/src/commands.rs#L1855-L1864 but use https://github.com/helix-editor/helix/blob/87a720c3a13ccc7245f5b0befc008db5bd039032/helix-core/src/selection.rs#L607-L614 instead
Is anyone working on this one at the moment? I'd like to make my first contribution
I'm not against this, just asking what is a usecase? The only situation I can see is something like selecting parentheses/brackets and delete them, but for that I can use existing keybinds.
Did you have something specific in mind for this command @kirawi? I also wonder if we need a command for this given that we have surround tools builtin while Kakoune does not
It was requested by https://matrix.to/#/!zMuVRxoqjyxyjSEBXc:matrix.org/$bFvOW3o-qWGL_cSdJWwK1wE86NXUz8LFq7rBJtO6VMA?via=matrix.org&via=mozilla.org&via=envs.net and I thought it was simple enough (and because Kakoune included it).
https://github.com/mawww/kakoune/issues/550 is the issue that motivated it in Kakoune. I think right now it could also be useful for basic multi-character pairs.
Overall, I agree that it is a niche command and if you guys don't want to include the command I'd be indifferent to it.
The use-cases mentioned later in the issue are covered by surround tools. The original use-case I'm not sure I fully understand but it seems like it wouldn't come up often so I bet it could be covered instead by subselecting with a regex of ^.|.$. I've asked on matrix what the commenter's use-case is - I'm leaning towards not adding this unless there's something compelling
so I bet it could be covered instead by subselecting with a regex of
^.|.$.
for selections that span across lines, \A.|.\z can be used instead to not match beginning/end of line
