To get best results from build, it's recommend to install additional packages on
 | 
						|
build hosts (see :ref:`searxng.sh`).
 | 
						|
 | 
						|
.. _searxng.sh install buildhost:
 | 
						|
 | 
						|
Build and Development tools
 | 
						|
===========================
 | 
						|
 | 
						|
To Install tools used by build and development tasks in once:
 | 
						|
 | 
						|
.. tabs::
 | 
						|
 | 
						|
  .. group-tab:: SearXNG's development tools
 | 
						|
 | 
						|
     .. code:: sh
 | 
						|
 | 
						|
        $ sudo -H ./utils/searxng.sh install buildhost
 | 
						|
 | 
						|
This will install packages needed by SearXNG:
 | 
						|
 | 
						|
.. kernel-include:: $DOCS_BUILD/includes/searxng.rst
 | 
						|
   :start-after: START distro-packages
 | 
						|
   :end-before: END distro-packages
 | 
						|
 | 
						|
and packages needed to build documentation and run tests:
 | 
						|
 | 
						|
.. kernel-include:: $DOCS_BUILD/includes/searxng.rst
 | 
						|
   :start-after: START build-packages
 | 
						|
   :end-before: END build-packages

Build docs
 | 
						|
==========
 | 
						|
 | 
						|
.. _Graphviz: https://graphviz.gitlab.io
 | 
						|
.. _ImageMagick: https://www.imagemagick.org
 | 
						|
.. _XeTeX: https://tug.org/xetex/
 | 
						|
.. _dvisvgm: https://dvisvgm.de/
 |

.. sidebar:: Sphinx build needs
 | 
						|
 | 
						|
   - ImageMagick_
 | 
						|
   - Graphviz_
 | 
						|
   - XeTeX_
 | 
						|
   - dvisvgm_
 | 
						|
 | 
						|
Most of the sphinx requirements are installed from :origin:`setup.py` and the
 | 
						|
docs can be build from scratch with ``make docs.html``.  For better math and
 | 
						|
image processing additional packages are needed.  The XeTeX_ needed not only for
 | 
						|
PDF creation, it's also needed for :ref:`math` when HTML output is build.
 | 
						|
 | 
						|
To be able to do :ref:`sphinx:math-support` without CDNs, the math are rendered
 | 
						|
as images (``sphinx.ext.imgmath`` extension).
 | 
						|
 | 
						|
Here is the extract from the :origin:`docs/conf.py` file, setting math renderer
 | 
						|
to ``imgmath``:
 | 
						|
 | 
						|
.. literalinclude:: ../conf.py
 | 
						|
   :language: python
 | 
						|
   :start-after: # sphinx.ext.imgmath setup
 | 
						|
   :end-before: # sphinx.ext.imgmath setup END
 | 
						|
 | 
						|
If your docs build (``make docs.html``) shows warnings like this::
 | 
						|
 | 
						|
   WARNING: dot(1) not found, for better output quality install \
 | 
						|
            graphviz from https://www.graphviz.org
 | 
						|
   ..
 | 
						|
   WARNING: LaTeX command 'latex' cannot be run (needed for math \
 | 
						|
            display), check the imgmath_latex setting
 | 
						|
 | 
						|
you need to install additional packages on your build host, to get better HTML
 | 
						|
output (:ref:`install buildhost <searxng.sh install buildhost>`).
 | 
						|
 | 
						|
.. tabs::
 | 
						|
 | 
						|
   .. group-tab:: Ubuntu / debian
 | 
						|
 | 
						|
      .. code-block:: sh
 | 
						|
 |

         $ sudo apt install graphviz imagemagick texlive-xetex librsvg2-bin

 |

      .. code-block:: sh

         $ sudo pacman -S graphviz imagemagick texlive-bin extra/librsvg

For PDF output you also need:

   .. group-tab:: Ubuntu / debian
 | 
						|
 |

Lint shell scripts

==================
 |

To lint shell scripts we use ShellCheck_ - a shell script static analysis tool
 | 
						|
(:ref:`install buildhost <searxng.sh install buildhost>`).
