File-Specific Vim Configuration
383 words. Time to Read: About 3 minutes.It seems like an indicator of a powerful application if you can use it for a long time without any problems and then suddenly discover useful features that add to your enjoyment or productivity that you didn’t even know existed. This happens to me a lot with the Microsoft Office suite (imagine the look of boyish glee on my face as I discovered conditional formatting in Excel). This also happens to me in Vim all. the. time. Granted, this may be more because of a more specialized interface and low discoverability. But, it’s still like an Easter egg hunt that you come across that you weren’t expecting because it’s the middle of October!
So here’s the #spoopy Halloween egg for today: Language-Specific Vim Configuration.
The Tip
Have you ever wanted to have some custom functions, settings, or key-bindings, but only for a specific language, without losing the ability to use those keybindings when working on other languages? Or (like in my case), multiple languages have a “build” command, but the command is different for each language, and it would be nice to have <leader>b do the building for each language so I don’t have to learn a million different muscle memories.
Introducing the ftplugin Directory
Inside your home directory, there is a .vim directory. Inside this .vim directory, you can put a directory called ftplugin (short for “file-type plugin”). Inside this directory, you can put <language>.vim files for each language you’d like to configure for. For instance, the plugin for the Rust language provides the commands :CBuild and CRun, but no keymappings. (I’m learning Rust, my first compiled language – pray for me) So, I created a ~/.vim/ftplugin/rust.vim file, and right now, all it has are these contents:
nnoremap <Leader>b :CBuild<Enter>
nnoremap <Leader>r :CRun<Enter>
I’m sure I’ll add more to it as I come up with more shortcuts and handy little settings, but that’s all I really wanted right now.
Clutter-Free Configuration
That’s the whole tip! I thought it was neat and wanted to share it. I like that you can separate things out into different files so that you don’t end up with one long convoluted .vimrc file. If you have any cool language-specific customizations or key-mappings that save you time, share them with me!
Happy configuring!
