Development

File layout

This repository contains the following files and directories:

• autoload/erlang_complete.erl: Erlang script which can analyse the code base and calculate the list of modules and the list of functions in a module.

• autoload/erlang_complete.vim: This script contains most of vim-erlang-omnicomplete's functionality on the Vim side.

  This functionality is here (instead of plugin/erlang_omnicomplete.vim) so that Vim's autoload functionality (:help autoload) can make sure that this script is executed only when needed the first time.

• doc/vim-erlang-omnicomplete.txt: This file contains the user documentation of vim-erlang-omnicomplete.

• ftplugin/erlang.vim: This script sets up vim-erlang-omnicomplete when an Erlang source file is opened.

• plugin/erlang_omnicomplete.vim: This script sets up vim-erlang-omnicomplete when Vim is started. It is kept small so that the effect on Vim's startup time is minimal.
