This provides vim syntax highlighting for the Madlang text generation language.

Using vim-plug:

Plug 'vmchale/madlang-vim'

You can also install with the madlang executable:

 $ madlang vim

If you want, you can add the following to your .vimrc:

autocmd BufWritePost *.mad MadlangCheck

This will automatically check syntax of madlang files every time you write the buffer. You can also set g:syntastic_madlang_checkers manually if you do not want the default linter to run.

If you get stuck, typing

:h madlang

will bring up the help for this plugin.

The highlighting should look like the following:
