docs_chunks

An experimental tool to extract EDoc or OTP XML documentation and attach it as Docs chunk.

Usage

By default Erlang modules don't have docs chunks and so iex> h will not find docs:

iex> h :sets
#=> :erlang was not compiled with docs

Install docs_chunks:

mix escript.install github wojtekmach/docs_chunks

Attach chunks for the sets module:

docs_chunks -otp-xml $HOME/src/otp sets
#=> Reading /Users/wojtek/src/otp/lib/stdlib/doc/src/sets.xml
#=> Writing /Users/wojtek/.asdf/installs/erlang/22.1.3/lib/stdlib-3.10/ebin/sets.beam

Note your OTP installation likely does not have documentation XMLs and in that case clone https://github.com/erlang/otp repository and pass that as the given OTP path.

Now iex> h works:

iex> h :sets

                                     :sets

Sets are collections of elements with no duplicate elements. The representation (...)

You can create docs chunks for the stdlib app like this:

docs_chunks -otp-xml-stdlib $HOME/src/otp
#=> Reading /Users/wojtek/src/otp/lib/stdlib/doc/src/array.xml
#=> Writing /Users/wojtek/.asdf/installs/erlang/22.1.3/lib/stdlib-3.10/ebin/array.beam
#=> Reading /Users/wojtek/src/otp/lib/stdlib/doc/src/base64.xml
#=> Writing /Users/wojtek/.asdf/installs/erlang/22.1.3/lib/stdlib-3.10/ebin/base64.beam
#=> ...)

Erlang Projects

Let's now attach docs chunks for an Erlang project, for example... the docs_chunks project itself:

git clone wojtekmach/docs_chunks
cd docs_chunks
mix compile
docs_chunks -edoc src/docs_chunks.erl _build/dev/lib/docs_chunks/ebin/
#=> Reading src/docs_chunks.erl
#=> Writing _build/dev/lib/docs_chunks/ebin/docs_chunks.beam

If your project is built with Mix or Rebar3, you can use this shortcut too:

docs_chunks -project
#=> Reading src/docs_chunks.erl
#=> Writing _build/dev/lib/docs_chunks/ebin/docs_chunks.beam
#=> Reading src/docs_chunks_cli.erl
#=> Writing _build/dev/lib/docs_chunks/ebin/docs_chunks_cli.beam

iex -S mix
iex> h :docs_chunks

                                  :docs_chunks

A module to extract docs and attach them as chunks.

ExDoc

Since we have docs chunks attached to beam files we can use ExDoc:

mix escript.install hex ex_doc
ex_doc docs_chunks "0.1.0" _build/dev/lib/docs_chunks/ebin --main docs_chunks

If everything went well you should see docs like these: wojtekmach.github.io/docs_chunks/docs_chunks.
