Making commands work only for chosen filetype(s)

I want to map F2 to compiling tex files, and F3 for viewing tex files.

This is what I put in my .vimrc:

if &filetype == "tex"
nnoremap <F2> :Latexmk<cr>
inoremap <F2> <Esc>:Latexmk<cr>a
nnoremap <F3> :LatexView<cr>
inoremap <F3> <Esc>:LatexView<cr>a
endif

These Latex* commands are from LaTeX-Box plugin. I can execute them manually without any problems. Typing :echo &filetype in any *.tex file returns tex.

You have two methods…

  • Create a self-clearing group in your vimrc and add as many autocommands as needed:

    augroup Tex
    autocmd!
    autocmd FileType tex nnoremap <buffer> <F2> :Latexmk<cr>
    autocmd FileType tex nnoremap <buffer> <F3> :LatexView<cr>
    autocmd FileType tex inoremap <buffer> <F2> <Esc>:Latexmk<cr>a
    autocmd FileType tex inoremap <buffer> <F3> <Esc>:LatexView<cr>a
augroup END

  • Use a ftplugin:

    Put the following in after/ftplugin/tex.vim:

    nnoremap <buffer> <F2> :Latexmk<cr>
nnoremap <buffer> <F3> :LatexView<cr>
inoremap <buffer> <F2> <Esc>:Latexmk<cr>a
inoremap <buffer> <F3> <Esc>:LatexView<cr>a

The second method is recommended because it is a lot cleaner and less expensive than the first.

I replaced the code above with this:

autocmd FileType tex nnoremap <buffer> <F2> :Latexmk<cr>
autocmd FileType tex nnoremap <buffer> <F3> :LatexView<cr>
autocmd FileType tex inoremap <buffer> <F2> <Esc>:Latexmk<cr>a
autocmd FileType tex inoremap <buffer> <F3> <Esc>:LatexView<cr>a
