Lingua Franca Plugin for Vim

This Vim plugin provides basic support for Lingua Franca files. It brings basic syntax highlighting, basic indentation rules and rudimentary text-object support for the target code blocks.

Installation

The best and easiest solution for installing the Plugin is one of the available Plugin managers for Vim. If you're using vim-plug, simply add the following:

Plug 'lf-lang/lingua-franca.vim'

Manual installation

You can install this plugin without a plugin manager simply by doing:

  • If you're using Vim 
    git clone https://github.com/lf-lang/lingua-franca.vim ~/.vim/pack/plugins/start/lingua-franca.vim
  • If you're using Neovim 
    git clone https://github.com/lf-lang/lingua-franca.vim ~/.config/nvim/pack/plugins/start/lingua-franca.vim

You can then update the plugin simply by git pulling it.

Caveats

  • There are some bugs with the nested syntax highlighting where some lines aren't highlighted; they likely originate in Vim's syntax highlight engine and I don't think changes at the plugin level can fix them.
  • The target language of your file is determined when the filetype is set. So, if you decide to change the target while editing the file, you need to either:
    • do :set ft=linguafranca
    • delete and reopen the buffer
    • close and reopen (n)vim

Indentation

Due to the nature of Vim's indentation rules (the fact that they are regex based), those rules are pretty much all “ad-hoc”. I think what it is there now is better than nothing, but if you find an example of a situation where the automatic indenting isn't satisfying, please open an issue.
