vim-erlang-spec

Generate specifications for your Erlang functions.

When you are inside the function, call :ErlangSpec and this script will produce specification for it. It won't fill in the argument types for you, though.

Installation

• Pathogen git clone https://github.com/melekes/vim-erlang-spec ~/.vim/bundle/vim-erlang-spec
• Vundle Bundle 'melekes/vim-erlang-spec'
• NeoBundle NeoBundle 'melekes/vim-erlang-spec'

Add a mapping to your ~/.vimrc (change the key to suit your taste):

nnoremap <leader>s :ErlangSpec<CR>

Alternative way - TypEr

If you are new to Erlang, you may be not aware of TypEr - tool, which can be used to generate type annotations for functions. You can read about it here or in the "Erlang Programming" book ("TypEr: Success Types and Type Inference").

TODO

• transform record to record type (#person{name=Name} => #person{})
• parse is_integer and other simple guards in when block (f(N, _) when is_integer(N) => f(N, _) -> any() when N :: integer())
