kakoune plugin to enhance some primitives with bigger selections.
Add auto-percent.kak to your autoload dir: ~/.config/kak/autoload/.
Or via plug.kak:
plug 'delapouite/kakoune-auto-percent'
Some normal commands only make sense when they operate on selections bigger than the simple cursor selection.
For instance, pressing s in normal mode with just a single cursor selection is not really useful.
With this script, pressing s will first select the whole content of the buffer with %. Hence the name of this plugin.
When the main selection is bigger than 1 char or/and they are more than 1 selection, the default behavior is applied.
Here are the normal commands affected by this script:
- select:
s→%s - split:
S→%S - split on new lines:
<a-s>→%<a-s> - split on boundaries:
<a-S>→%<a-S> - keep matching:
<a-k>→%<a-s><a-k> - keep not matching:
<a-K>→%<a-s><a-K> - rotate selections forward:
)→%<a-s>) - rotate selections backward:
(→%<a-s>( - rotate selections contents forward:
<a-)>→%<a-s><a-)> - rotate selections contents backward:
<a-(>→%<a-s><a-(>
If the commands above display a prompt and you cancel it (with <esc>), you'll get back the original cursor.
Same thing for matching errors.
To remove the mappings if needed, run auto-percent-unmap (auto-percent-map to add them back).
Another good candidate to tweak: merge continuous selections <a-m>
The select-complement command is useful in oops scenarios. Let's illustrate with a quick example.
You want to split the elements of the following list (foo, bar, qux) in order to rotate them (with <a-)>) later on.
So you do <a-i>b to select inside the parens and then do s, <ret>. Oops, you've made a mistake by selecting the commas and
spaces which was not what you had in mind. The correct operation would have been to use S (split) instead of s.
Unfortunately, Kakoune does not currently provide on easy way to undo a selection.
You can fix your problem with select-complement. What it does is going back in time and doing the <a-i>b again (using auto marks),
and running the S command with the same regex you've just provided.
So to recap, with this command you can toggle between:
s<->S<a-k><-><a-K>
Note that it's only intented to work when you execute it immediately after.
This behavior is somehow similar to the one found in vis:
If only one selection exists x and y default to the whole file 0,$.
In Kakoune dialect: the x command is s (select), the y command is S (split) and the 0,$ address is % (whole buffer).
