Target Branches

There are different branches in this repository, each one targeting a specific Conan version:

master: It should be used to fix some documentation issue or add some missing documentation for features already available in Conan 1.x.
develop: It should be used for new features or hotfixes to be incorporated in the next Conan 1.x version.
release/2.0: It should be used to fix some documentation issue or add some missing documentation for features already available in Conan 2.x.
develop/2.0: It should be used for new features or hotfixes to be incorporated in the next Conan 2.x version.

Style Guidelines

These guidelines are just general good practices for the formatting and structure of the whole documentation and do not pretend to be a stopper for any helpful contribution. Any contribution that may include relevant information for Conan users will always be welcomed.

Conan documentation is written in reStructuredText and follows reStructuredText Markup Specification.

Quick reStructuredText is also used for reference.

Any detail not covered by this guidelines will follow the aforementioned rules.

Section titles

Use section titles in this level of importance:

Section Title
=============

Section Title
-------------

Section Title
+++++++++++++

Section Title
^^^^^^^^^^^^^

Text emphasis/highlighting

Bold text to highlight important text:

Note the simple scenario of a **header-only** library. Such package...

Italics to refer to file names, directory names and paths.

If you have a look to the *test_package* folder, you will realize that the *example.cpp* and the *CMakeLists.txt* files don't have
anything special. The *test_package/conanfile.py* file is...

Command inline literals to refer to command line, both full commands and command line arguments, or any extract of a full command.

To create a conan package you can use :command:`conan create`.  You can see a :command:`git clone` command... You may call it with the :command:`--keep-source` option to avoid deleting and fetching the source.

Inline literals to refer to code or text inside recipes:

 ``package()`` -> conanfile.py method
 ``cmake`` -> generator in conanfile.txt
 ``settings`` -> variable inside a ConanFile class in conanfile.py

Like this:

Note that the ``build_id()`` method uses the ``self.info_build`` object to alter the build hash.

Other names like CMake, Autotools, Conan, Visual Studio should not be emphasized, just use a capital letter or follow the convention (like first and second capitalized letters for CMake).

code-blocks

Use code-blocks for code snippets or command line actions and follow the specific language indentation. Documentation makes an extensive use of bash, python, txt and cmake code-blocks.

.. code-block:: python

    from conans import ConanFile

    class EigenConan(ConanFile)
        name = "eigen"
        version = "3.3.4"

        def source():
            tools.get("https://some_url.org")
            ...

.. code-block:: text

    [requires]
    poco/1.9.4
    zlib/1.2.11

.. code-block:: bash
   :emphasize-lines: 3

    $ conan source . --source-folder src
    $ conan install --install-folder build_x86 -s arch=x86
    $ conan build . --build-folder build_x86 --source-folder src
    $ conan export-pkg . Hello/0.1@user/stable --build-folder build_x86

Indentation and line length

Make sure all indentation is done with spaces. Normally 2 space indentation for bulleted lists and 4 space indentation for code blocks. In some cases a 3 space indentation is needed for reStructuredText specifics like toc-trees:

.. toctree::
   :maxdepth: 2

   creating_packages/getting_started
   creating_packages/package_repo

The maximum line length for documentation is 140 characters except for lines inside code-blocks, external links or references.

Do not leave any unnecessary or trailing spaces.

Text boxes

Also called Admonitions, they are eye-catching texts with a clear purpose like warnings, tips or important content.

Use them in the following importance order:

caution
attention
warning
important
note
tip

.. warning::

    In the ConanCenter repository there are binaries for several mainstream compilers...

.. tip::

    Using profiles is strongly recommended. Learn more about them...

References

References are commonly used in the documentation and it's always a good way to highlight texts and give an implicit or explicit importance to something.

Internal reference

Use an internal reference when you want to refer to a specific section in this documentation. Most of the sections have a reference mark just before their names so you can reference it.

.. _conan_export_pkg_command:

conan export-pkg
================

...

To add a reference to the conan export-pkg command from another text:

Read more about the :ref:`conan export-pkg<conan_export_pkg_command>` command.
Or reference the :ref:`conan_export_pkg_command` directly.

External references

Use external references with external URL at the bottom of the file like this:

Submit a pull request to include it in `conan-center-index`_.
...
...

.. _`conan-center`: https://center.conan.io

In case you want to use explicit external references with a link, make sure it doesn't exceed the maximum line length, otherwise it should considered to be written as a normal external reference.
