OCaml Development in Vim

This is a quick run-through of how I set up my development environment in vim:

Install pathogen.vim

mkdir -p ~/.vim/autoload ~/.vim/bundle; \
curl -Sso ~/.vim/autoload/pathogen.vim \
    https://raw.github.com/tpope/vim-pathogen/master/autoload/pathogen.vim

Add the following to ~/.vimrc:

execute pathogen#infect()
syntax on
filetype plugin indent on

Install Syntastic

cd ~/.vim/bundle
git clone https://github.com/scrooloose/syntastic.git

Then quit vim and used :Helptags to check installs so far have worked.

Install Merlin

opam switch 4.01.0dev+trunk
opam update
opam upgrade
opam install merlin

Add the following to ~/.vimrc

:set rtp+=~/.opam/4.01.0dev+trunk/share/ocamlmerlin/vim
:set rtp+=~/.opam/4.01.0dev+trunk/share/ocamlmerlin/vimbufsync
let g:syntastic_ocaml_checkers=['merlin']

:SyntasticInfo will return a list of syntax checkers available to Syntastic, check that this now includes merlin

Install OCP Indent

opam install ocp-indent

Add the following to ~/.vimrc

autocmd FileType ocaml source /home/heidi-ann/.opam/4.01.0dev+trunk/share/typerex/ocp-indent/ocp-indent.vim
