Markus Heiser 757ebb5d9f [fix] brands: add variables from build env to grunt process
We have some variables in the build environment which are also needed in the
grunt process when building themes.  Theses variables are relavant if one
creates a fork with its own branding.  We treat these variables under the term
'brands'.

======================
Development Quickstart
======================
.. sidebar:: :ref:`makefile`
For additional developer purpose there are :ref:`makefile`.
This quickstart guide gets your environment set up with searx. Furthermore, it
gives a short introduction to the ``manage.sh`` script.
How to setup your development environment
=========================================
.. sidebar:: :ref:`make pyenv <make pyenv>`
Alternatively use the :ref:`make pyenv`.
First, clone the source code of searx to the desired folder. In this case the
source is cloned to ``~/myprojects/searx``. Then create and activate the
searx-ve virtualenv and install the required packages using ``manage.sh``.
.. code:: sh
cd ~/myprojects
git clone https://github.com/asciimoo/searx.git
cd searx
virtualenv searx-ve
. ./searx-ve/bin/activate
./manage.sh update_dev_packages
How to run tests
================
.. sidebar:: :ref:`make test.unit <make test>`
Alternatively use the ``test.pep8``, ``test.unit``, ``test.robot`` targets.
Tests can be run using the ``manage.sh`` script. Following tests and checks are
available:
- Unit tests
- Selenium tests
- PEP8 validation
- Unit test coverage check
For example unit tests are run with the command below:
.. code:: sh
./manage.sh unit_tests
For further test options, please consult the help of the ``manage.sh`` script or
read :ref:`make test`.
How to compile styles and javascript
====================================
.. _less: http://lesscss.org/
.. _NodeJS: https://nodejs.org
How to build styles
-------------------
Less_ is required to build the styles of searx. Less_ can be installed using
either NodeJS_ or Apt.
.. code:: sh
sudo -H apt-get install nodejs
sudo -H npm install -g less
OR
.. code:: sh
sudo -H apt-get install node-less
After satisfying the requirements styles can be build using ``manage.sh``
.. code:: sh
./manage.sh styles
How to build the source of the themes
=====================================
.. _grunt: https://gruntjs.com/
Grunt_ must be installed in order to build the javascript sources. It depends on
NodeJS, so first Node has to be installed.
.. code:: sh
sudo -H apt-get install nodejs
sudo -H npm install -g grunt-cli
After installing grunt, the files can be built using the following command:
.. code:: sh
make themes
Tips for debugging/development
==============================
.. sidebar:: :ref:`make run`
Makefile target ``run`` already enables debug option for your developer
session / see :ref:`make run`.
Turn on debug logging
Whether you are working on a new engine or trying to eliminate a bug, it is
always a good idea to turn on debug logging. When debug logging is enabled a
stack trace appears, instead of the cryptic ``Internal Server Error``
message. It can be turned on by setting ``debug: False`` to ``debug: True`` in
:origin:`settings.yml <searx/settings.yml>`.
.. sidebar:: :ref:`make test`
Alternatively use the :ref:`make test` targets.
Run ``./manage.sh tests`` before creating a PR.
Failing build on Travis is common because of PEP8 checks. So a new commit
must be created containing these format fixes. This phase can be skipped if
``./manage.sh tests`` is run locally before creating a PR.
