This is an adaption of vim-stylishask by alx741. It's basically a search and replace.
Vim-brittany integrates with brittany so every time you save a Haskell source file it gets automatically prettified.
Simply using :%!brittany replaces your whole source file with an error message
from brittany when you happen to have a syntax error in your code, this
plugin manages that annoyance.
Compatible with Vundle, Pathogen, Vim-plug.
By default, vim-brittany will format your code automatically when saving a
Haskell source file, but you can use the :Brittany command at any time to
format the current file.
To apply vim-brittany on a range, either write the range manually or
visually select the desired code and then invoke :Brittany.
Use :BrittanyEnable, :BrittanyDisable, :BrittanyToggle to enable, disable, or
toggle running brittany on save.
Trigger brittany when saving (default = 1):
g:brittany_on_save = 1Brittany configuration file to use (default = "" == Use default ~/.brittany/config.yaml):
g:brittany_config_file = "/path/to/config.yaml"
