Guideline for contributing documentation#

The DLite documentation is written in Markdown. This include both the README files and documentation found in the doc/ subdirectory.

Common to both is that the text should be as easy and natural as possible to read and write both from the terminal, in an editor and rendered in a web browser. Hence, the following recommendations:

  • Write one sentence per line, in order to get an easier to read output from git diff. This improves readability and understandability when performing reviews on GitHub.

  • For README files, use the underline (setext) style format for main and sub-headers. For example:

    Header level 1
==============
...

Header level 2
--------------
...

    For documentation, follow the style used by the original contributor.

  • Avoid the use of raw HTML.

  • Links become more readable if you place them at the end of the document using square brackets. Example:

A link to [SOFT].
...

End of document.


[SOFT]: https://www.sintef.no/en/publications/publication/1553408/

  • Use .md as file extension for all Markdown files.

The README files are intended to document the overall project or the content in a subdirectory. These should therefore render nicely on GitHub. Hence, use CommonMark or possible GitHub-flavored Markdown. For README files, keep the maximum line length at 79 characters for easy viewing in a 80 character wide terminal.

The Markdown files in the doc/ subdirectory are intended to be included in the Sphinx-generated online documentation. We make use of the MyST Markdown extension to convert all markdown syntax to rich structured text (RST) prior to letting Sphinx generate the HTML (or other) documentation.

Figures#

Please place figures in the doc/_static/ directory. If you use draw.io, it is recommended that you save the figure in svg format. Then it renders well in browsers and is easy to find and edit for collaborators.

Examples#

Write your python examples in the same way as done in the official Python documentation, by preceeding expressions with >>> and the expected output on the next line below the >>> . Add a blank line at the end of the code listing. For example

```python
    # Here is a python example
    >>> x = 1 + 1
    >>> x
    2

```

This will show up nicely highlighted in the generated documentation:

    # Here is a python example
    >>> x = 1 + 1
    >>> x
    2

and will facilitate checking the examples by running

python -m doctest <filename>

on your markdown file.

It is recommended to indent your code examples with 4 spaces. That makes it easy to copy the correct doctest output into your example. For more info, see the guide for documentation testing.

Please note that examples from Python sources will show up with a small >>> button in the top right of the code listing box. If you click that button, it will toggle the prompt and output on or off, making it easy to copy/paste from examples.
