fold label

[shawn wilson]

is there a way to specify how a fold gets labeled? the default (of the
first line with visible text is generally correct) but sometimes, my
fold will start at a line with only /* or // or #. and a fold label
with one of these is next to useless.

See
:h 'foldtext'
:h fold-foldtext

per foldtext -
Leading white space, "//" or "/*" and the text from the 'foldmarker'
and 'commentstring' options is removed.

i have:
let perl_fold=1 " Perl
and try:
autocmd FileType perl set commentstring='# %s'

but, this doesn't seem to do anything.

also, it seems i was wrong about // - that does seem to work correctly in js

Hi shawn!

I am not sure, what you are trying to do here. But here is an example of
how I customize my folded text. It is based on an idea by Greg Sexton
mentioned at

if i do something like this in perl code:
###################
# useless comment #
###################

and the line of #s is the first line of the fold, vim does:
+-- 3 lines: ##################------------------------------------------------------------------------------
which is, of course, next to useless.

thanks. i think i'll have the same display issue i'm currently having.
however i think i can change this:
getline(fs) =~ '^\s*$'
to something like:
getline(fs) =~ '^[^#\\ ]*$'
and that might work. either way, i think i can see how to make it work
with that.
