I have a list of files grouped by file extension. I am trying to create
a fold for each of the groups. For this purpose I created the following
Vim function:
function! FoldByExtension()
let s:searchSave = @/
let s:wrapscanSave = &ws
set nowrapscan
normal zE
1
while 1
try
.,/\v^.*\.(.*)\n(.*\.\1\n)*\zs.+(\1)@<!$/-1fold
normal nj
catch /E385/
break
endtry
endwhile
.,$fold
let &ws = s:wrapscanSave
let @/ = s:searchSave
endfunction
With re=1 Vim correctly processes the following list:
#v+
foo.bat
bar.bat
baz.bat
foo.com
bar.com
baz.com
foo.txt
bar.txt
baz.txt
#v-
creating 3 folds, 3 elements each. With re=2 it creates a single fold
containing all the lines.
