Development Quickstart
======================
.. sidebar:: :ref:`makefile`
.. _npm: https://www.npmjs.com/
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``.
Searx loves developers, just clone and start hacking. All the rest is done for
you simply by using :ref:`make <makefile>`.
.. code:: sh
cd ~/myprojects
git clone https://github.com/searx/searx.git
cd searx
python3 -m venv searx-ve
. ./searx-ve/bin/activate
./manage.sh update_dev_packages
Here is how a minimal workflow looks like:
How to run tests
================
1. *start* hacking
2. *run* your code: :ref:`make run`
3. *test* your code: :ref:`make test`
.. sidebar:: :ref:`make test.unit <make test>`
If you think at some point something fails, go back to *start*. Otherwise,
choose a meaningful commit message and we are happy to receive your pull
request. To not end in *wild west* we have some directives, please pay attention
to our ":ref:`how to contribute`" guideline.
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: https://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
make node.env
After installing grunt, the files can be built using the following command:
If you implement themes, you will need to compile styles and JavaScript before
*run*.
.. code:: sh
make themes
Don't forget to install npm_ first.
Tips for debugging/development
==============================
.. tabs::
.. sidebar:: :ref:`make run`
.. group-tab:: Ubuntu / debian
Makefile target ``run`` already enables debug option for your developer
session / see :ref:`make run`.
.. code:: sh
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>`.
sudo -H apt-get install npm
.. sidebar:: :ref:`make test`
.. group-tab:: Arch Linux
Alternatively use the :ref:`make test` targets.
.. code-block:: sh
sudo -H pacman -S npm
.. group-tab:: Fedora / RHEL
.. code-block:: sh
sudo -H dnf install npm
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.
