|
|
" This checker runs 'perl -c' against your file, which in turn executes
|
|
" any BEGIN, UNITCHECK, and CHECK blocks, and any use statements in
|
|
" your file. This is probably fine if you wrote the file yourself,
|
|
" but it can be a problem if you're trying to check third party files.
|
|
" If you are 100% willing to let Vim run the code in your file, set
|
|
" g:syntastic_enable_perl_checker to 1 in your vimrc to enable this
|
|
" checker:
|
