A meta char for folding

[juanpabloaj]

why don't add a meta char for folding? example

if I have this snippet

snippet f
function ${1:funName}(${2:args}){
    ${3:#code}
}

when I press f<tab> the snippet is inserted

function funName(args){
    #code
}

if a meta char is _ when I press f_<tab> the folding is added to existent snippet and insert snippet with folding

function funName(args){ "{{{
    #code
} "}}}

The same idea for a meta char for add commented documentation a snippet

f@<tab> 
...
function funName(args){
" @funName : description 
    #code
}

enjoy your great suggestion:

If you come up with a nice default implementation for AddFolding we can
move the code into the autoload directory and distribute it as official
implementation.

Probably the char should be configurable?
What about prefixing instead?

yes, the char should be configurable.
yes, prefixing is a good idea, the _ char case was a example.

maybe similar to python decorators

[juanpabloaj]

my question is, how change the comment in any filetype?

a big if conditional ?

[MarcWeber]

Have a look at this implementation:
https://github.com/MarcWeber/vim-addon-commenting

and the referenced projects. They all either use the existing Vim
options or introduce their own settings / dictionaries to look up the
commenting chars.

The function found in that tries to always return a line based
commenting char if available.

In the code you can use &filetype setting to make the func dynamically
use different commenting char.

to simplify I use this

    let g:commentChar = { 
        \ 'vim': '"',
        \ 'c': '//',
        \ 'cpp': '//',
        \ 'sh': '#',
        \ 'python': '#' 
        \}
    " url https://github.com/garbas/vim-snipmate/issues/49
    fun! AddFolding(text)                                                                                                               
        return g:commentChar[&ft]." {{{\n".a:text."\n".g:commentChar[&ft]." }}}"
    endf
