After saying `make refdoc' or `make refdoc-venv' the `site/' directory
contains the FreeType API reference. You need python and pip to make this
target.
There are two ways to generate the documentation:
1. Using `make refdoc':
- Ensure `python' and `pip' are available.
- Install pip package `docwriter' with `pip install --user docwriter'.
- Make target with `make refdoc'.
- This target can be run offline once required packages are installed.
2. Using `make refdoc-venv' (requires internet access):
- Ensure `python', `pip' and python package `virtualenv' are available.
- Make target with `make refdoc-venv'.
- This may or may not require internet access every time depending on
pip and system caching.
This also works with Jam: Just type `jam refdoc' in the main directory.
Some troubleshooting tips:
* Regularly run `pip install --upgrade docwriter' to check for updates which
may include bug fixes.
* Ensure that `docwriter' is installed in the same python target that
`make refdoc' uses (python3/python2/python).
* `pip' and `python' may point to different versions of Python. Check using
`python --version' and `pip --version'.
* If none of this works, send a mail to `freetype-devel@nongnu.org' or file
an issue at `https://github.com/freetype/docwriter/issues'.
