Hey Andrew, i really like your plugin! Thx for the awesome work! I use it many times daily.

Thank you for the kind words :).

I want to switch between the following variable declarations:

Try putting this in ~/.vim/ftplugin/sh.vim, so it gets run for every bash file:

let b:switch_custom_definitions =
      \ [
      \   {
      \     '$\(\k\+\)':     '${\1}',
      \     '${\(\k\+\)}':   '"${\1}"',
      \     '"${\(\k\+\)}"': '$\1',
      \   }
      \ ]

The first transforms "$ followed by only keyword charactersinto${..}, the second matches $, then {, then keyword characters, then }`, and you can guess the third.

Hey Andrew,

thx for your fast reply!

i tested it and it has a little problem with underscores in the var name.

"${OPT_PATH_PATCH}"

is switching to

"${OPTPATHPATCH}"

do you have a hint on how to make it underscore aware?

i will only use uppercase and lowercase letters and underscores in my variable names.

thx again!

To me, this seems like a conflict with some other switch mapping. Is it possible you have the example from the documentation installed that transforms snake_case into camelCase? As I said in the docs:

Note that this particular example is NOT included as a built-in, since it may overshadow other ones and is probably not that useful, either

I'd recommend you only add that example as a buffer-local one for filetypes you tend to use it often, or add it with a different mapping, like I suggest here:

switch.vim/doc/switch.txt

Lines 295 to 306 in 8f76655

	let g:variable_style_switch_definitions = [
	\ {
	\ '\<[a-z0-9]\+_\k\+\>': {
	\ '_\(.\)': '\U\1'
	\ },
	\ '\<[a-z0-9]\+[A-Z]\k\+\>': {
	\ '\([A-Z]\)': '_\l\1'
	\ },
	\ }
	\ ]
	nnoremap + :call switch#Switch({'definitions': g:variable_style_switch_definitions})<cr>
	nnoremap - :Switch<cr>

Could you check if this is, in fact, the problem?

[divramod]

you were right.

i have it running now.

thx a lot!

this will really give me a timeboost :-)

Excellent, I'm glad to hear I've been managing to recruit people to the Vim side :D. I'll try to remember to collect that beer!
