Vim inoremap for specific filetypes

Question

I\'ve added some simple inoremap commands to my .vimrc to help with parens and brackets completion, but I only want them to apply to php files.

Answer 1

Use autocmd FileType:

autocmd FileType php,c,java inoremap ( ()<Esc>i

Answer 2

put them in a this file

~/.vim/ftplugin/php.vim

Answer 3

There may be a better way to do it, but this should work:

autocmd FileType php call Inoremaps()
fu! Inoremaps()
   inoremap ...
endfu

Answer 4

You need to do 2 things:

• create a mapping local to a specific buffer by using the <buffer> option for inoremap.
• load the mappings for just a specific filetype.

This can be done via an autocommand in your .vimrc like so:

autocmd FileType php inoremap <buffer> ( ()<Esc>i

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/after/ftplugin/php.vim and place your mappings inside like so:

inoremap <buffer> ( ()<Esc>i
inoremap <buffer> { {<CR>}<Esc>ko
inoremap <buffer> <? <?php ?><Esc><Left>i

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

Answer 5

Add them to the ftplugin file in the after directory:

~/.vim/after/ftplugin/php.vim

Edit: This file, and maybe even the directory, will not be there by default. You may have to make it if you don't see it there.
