How to set conditional mappings in VIM (ie: depending on the extension of a file)?

原文 2012-12-02 20:19:27 4 2 vim/ mapping/ conditional

例如，如果文件扩展名为.js ，则如何将'<leader>r'映射到:!node % ，然后将其映射到:!make % otherwise？

General case, in your ~/.vimrc :

nnoremap <leader>r :!make %<cr>

JavaScript files, in ~/after/ftplugin/javascript.vim :

nnoremap <buffer> <leader>r :!node %

Or use the makeprg option. See :h makeprg .

Try this:

nnoremap <leader>r :!make %
autocmd FileType javascript nnoremap <leader>r :!node %
