Owl is a scientific computing library developed in the OCaml language. This repository contains the parser and tools to automatically build up the API Reference and Tutorial book for Owl.

The built documentation is hosted on owlbarn.github.io and my lab page. If you want to build a local copy of the whole documentation, please refer to the following instructions.

Step 1: You need to clone Owl's code repository from the Github, because the source files are needed to build up the documentation. The parser needs to parse both ml and mli files.

git clone https://github.com/owlbarn/owl.git

Step 2: Install Owl library. The parser needs to call a couple of functions from Owl library so you need to install Owl locally. Please refer to Owl's documentation to see how to install.

Step 3: Install Sphinx and plugin. You can use for example pip to install them. Python 2.7 should work fine. Owl uses sphinxcontrib.bibtex to generate bibliography.

pip install sphinx
pip install sphinxcontrib.bibtex

Step 4: When you finish installing all the dependencies, you need some configuration so the parser can find the Owl's source files. Enter into owl_guide root directory, edit the second line to make sure API_SRC points to the Owl's src folder. The following is an example on my laptop.

# Please only configure API_SRC to point to correct Owl src folder.
API_SRC="/Users/liang.wang/code/owl/src/"
...

Step 5: Building is simple, simple enter the owl_guide root directory, then make.

cd ./owl_guide
make

Step 6: The script will build both API Reference and Tutorial book locally. To check the building result locally, you can use a browser open the index.html saved in the _build folder.

open book/_build/html/index.html

When you are happy with your edits and how they look on the local copy, it is ready to go for a pull-request. Before you submit the pull-request, you need to first fork owlbarn.github.io to your own github account.

Then you need to install hub tool which is an extension of git. On Mac OSX, you can use brew to install it.

brew install hub

Then you can simply enter the following command in the owl_guide root directory.

make pull-request

It might take a while but you can soon see your pull-request on this page. After I merge these requests, you can immediately see your edits appeared on owlbarn.github.io. Hurray!

Sphinx allows you to build the documentation in other formats such as PDF. In this case, you need to enter into book subdirectory and build from there. Type make and you can see different options. E.g, build the documentation in PDF will look like this.

make latexpdf

It is highly appreciated if you can help me in improving Owl's documentation, it benefits the whole community of functional languages and scientific computing.

• If you want to improve the Tutorial Book, you need to edit the files in owl_guide/book/chapter directly in this repo. Then submit the PR and I will review it.

• If you want to improve the API Reference, you need to edit the corresponding mli files in Owl's repo then submit the PR to source code repository.
