Contribute to this Manual
=========================

A great way to contribute without writing code is to help writing
documentation. Please reach out before contributing as the software is still in
an alpha state and portions may not be worth documenting as it changes too
frequently.

Writing technical documentation
-------------------------------

All documentation is written in ReStructured Text and is available in the
`BlenderBIM Add-on docs directory
<https://github.com/IfcOpenShell/IfcOpenShell/tree/v0.8.0/src/blenderbim/docs>`_.
You can press the edit button on the top right on any documentation page to
quickly edit their content.

Links
^^^^^

You can link to

.. code-block:: restructuredtext

  `external websites
  <https://docs.readthedocs.io/en/stable/guides/cross-referencing-with-sphinx.html>`_

(note the space between the url and the link text).  You can also link to
sections on the same page, like

.. code-block:: restructuredtext

  :ref:`contribute/writing_docs:Writing technical documentation`
  
or with

.. code-block:: restructuredtext

  :ref:`custom text<contribute/writing_docs:writing technical documentation>`.
  
Traditional references like 
  
.. code-block:: restructuredtext
 
  `Writing technical documentation`_

work too but are discouraged. You can link to other pages, like this:

.. code-block:: restructuredtext

  :doc:`Hello World<hello_world>`

or sections within other pages, like this:

.. code-block:: restructuredtext

  :ref:`devs/installation:unstable installation`

We have ``autosectionlabel`` enabled so it is not necessary to manually create labels. The depth of sections
with automatic labels is set to 2, so the third level of titles
will not get automatic labels to avoid duplication.

You can still create labels manually. This way you would ensure links still works when documentation is refactored.

.. code-block:: restructuredtext

    .. _My label:

    My Section
    ==========

    :ref:`Link to My Section <My label>`

This link will work across the documentation. Make sure the label is globally unique.

Images
^^^^^^

The following colours and annotation styles should be used for annotating
images. All stroke widths are 3px with a corner radius of 3px.  Horizontal
underlines are 5px with a corner radius of 2px. The dark green is ``39b54a`` and
the light green is ``d9e021``.

.. image:: images/documentation-style.png

Special keywords such as **Technical Terminology** that the user should be
aware of should be bolded, titlecased, and used consistently. You *may*
use italics to emphasize words or phrases. Inline code must be ``quoted`` and
longer code snippets may use code blocks.

.. code-block:: bash

    cd /path/to/blenderbim
    ls

Be sure to specify the language to enable syntax highlighting.

.. code-block:: python

   print("Hello, world!")

A button may be used to point users to a critical sample file or
download.

.. container:: blockbutton

    `Visit critical link <https://bonsaibim.org>`__

You can use bulleted lists:

- Like.
- This.

Or ordered lists:

1. Like.
2. This.

.. note::

   Instead of writing "Note that XYZ ..." you should use notes sparingly to
   highlight "gotchas".

.. tip::

   Tips may be used to add a useful but optional suggestion.

.. warning::

   Warnings may be used to highlight common mistakes.

.. seealso::

    See also blocks should be used to reference `further reading
    <https://bonsaibim.org>`__ links.

Tables can be very annoying to format. You can use a CSV table instead.

.. csv-table::
   :header: "Foo", "Bar", "Baz"

    "ABC", "01", "02"
    "DEF", "03", "04"

Building documentation
----------------------

If you want to build the documentation locally, the documentation system uses
`Sphinx <https://www.sphinx-doc.org/en/master/>`_. First, install the theme and
theme dependencies:

.. code-block:: bash

    pip install furo
    pip install sphinx-autoapi
    pip install sphinx-copybutton

Now you can generate the documentation:

.. code-block:: bash

    cd /path/to/ifcopenshell/src/blenderbim/docs/
    make html
    cd _build/html
    python -m http.server

You will now have a local webserver running hosting the documentation.
