tabs<->spaces ?

[Rudxain]

I know I can, for example %|expand -t4 or %|unexpand -t3, and I can define a keybind macro to do that for me, but the indent-size is hard-coded. Is there some way to auto-detect the indent-size? or, at least, is there a way to "pass args" to a keybind?

Should this be a built-in feature? vscode has it

Is this a dupe of #2576 ?

In this specific case, macros don't need to prompt for an arg/param:

# example keystrokes: <backspace>e4;
# assumptions:
# - `C-s` bound to `save_selection`
# - `C-o` bound to `jump_backward`
[keys.normal.backspace]
# generic and manual
e.n = "@<C-s>%|expand -t"
# concrete and auto
e.2 = "@<C-s>%|expand -t2<ret><C-o>"
e.3 = "@<C-s>%|expand -t3<ret><C-o>"
e.4 = "@<C-s>%|expand -t4<ret><C-o>"
e.6 = "@<C-s>%|expand -t6<ret><C-o>"
e.8 = "@<C-s>%|expand -t8<ret><C-o>"
u.n = "@<C-s>%|unexpand -t"
u.2 = "@<C-s>%|unexpand -t2<ret><C-o>"
u.3 = "@<C-s>%|unexpand -t3<ret><C-o>"
u.4 = "@<C-s>%|unexpand -t4<ret><C-o>"
u.6 = "@<C-s>%|unexpand -t6<ret><C-o>"
u.8 = "@<C-s>%|unexpand -t8<ret><C-o>"

it's fast enough, but still no auto-detect

so eh... I came from Feat: implement %reg{} expansion by crs-io · Pull Request #15410 · helix-editor/helix, do you find a shorter form for this?

I forgot to update the keybinds 😅. This should work (not tested):

[keys.normal.backspace]
e = "@<C-s>%|expand -t%reg{t}<ret><C-o>"
u = "@<C-s>%|unexpand -t%reg{t}<ret><C-o>"

To "pass" the arg/param t, :set-register t 4 (example). Since set-register is a long command, it might be a good idea to add a keybind for that too

Thanks ... It helps the discussion for future sake.
