Is there a better way to map command call based on filetype [duplicate]

Answer 1

You need to do 2 things:

• Create a mapping local to a specific buffer by using the option for noremap.
• Load the mappings for just a specific filetype.

This can be done via an autocmd and FileType event in your .vimrc like so:

autocmd FileType perl noremap   :!perl %:p

The other way option is by creating a filetype plugin. (see :h ftplugin for more details)

A simple example is do create a file named, ~/.vim/ftplugin/perl.vim and place your mappings inside like so:

nnoremap   :!perl %:p

I personally lean more towards the ftplugin approach but having a everything in your .vimrc file can be nice.
