I installed perl-support.vim into ~/.vim (unzipped). When I create a new .pl file it shows me the default template, which means my installation is successful (I guess). I have already added filetype plugin on in ~/.vimrc & /etc/vimrc.
How do I enter a perl-support command?
The write up recommends typing \isu in normal mode for creating a new sub, but the moment I hit i vim changes into insert mode and nothing intended happens.
What am I doing wrong?
Make sure you've enabled ftplugins with the filetype plugin on command in .vimrc, and of course make sure that the file you're editing is recognized as a Perl file (usually, by having a known extension, but you can force the matter by issuing the command set filetype=perl. If filetype plugins aren't enabled, or if the filetype isn't recognized, then the rest of perl-support won't get loaded at all.
Thanks Brian. set filetype=perl works.
However, I wanted to do this everytime I open a .t test file - which my vim does not recognize as perl files because the interpreter statement is also custom.
I checked out :help syntax in vim and saw this.
mkdir ~/.vim/ftdetect
cd ~/.vim/ftdetect
vi t.vim
which contains
au BufRead,BufNewFile *.t set filetype=perl
which says - if file extension .t set filetype = perl.
This can be useful for any custom extensions also.
