Matchit does not work in a 2-line C file with the following contents:
#if FOO
#endif
Steps to reproduce:
vim -u NONE -U NONE
:set nocompatible
:filetype plugin indent on
:syntax on
:setf c
:runtime macros/matchit.vim
:call append(line('$'), "#if FOO")
:call append(line('$'), "#endif")
:1del _
:normal 1G0
:normal %
Note that the cursor does not move to the second line until you set
re=1. This boils down to the following condition in s:Wholematch being
true for re=0 and false for re=1:
if a:string !~ prefix . group . suffix
with a:string being "#if FOO" and the regexp
"^\%(\%((\|)\|{\|}\|[\|]\|^\s*#\s*if\(\|def\|ndef\)\>\|^\s*#\s*elif\>\|^\s*#\s*else\>\|^\s*#\s*endif\>\|(\|)\|{\|}\|\[\|\]\|\/\*\|\*\/\|#\s*if\%(def\)\=\|#\s*else\>\|#\s*elif\>\|#\s*endif\>\)\)\(\%>1c.*$\)\@="
Sorry, I couldn't simplify it any further; for some reason this does not
work when put in a simple script as follows (both produce 1):
set re=1
echo "string !~ regexp == " . string(string !~ regexp)
set re=2
echo "string !~ regexp == " . string(string !~ regexp)
