.. _makefile:
================
Makefile Targets
================
.. sidebar:: build environment
Before looking deeper at the targets, first read about :ref:`makefile setup`
and :ref:`make pyenv`.
With the aim to simplify development cycles, started with :pull:`1756` a
``Makefile`` based boilerplate was added.
The usage is simple, just type ``make {target-name}`` to *build* a target.
Calling the ``help`` target gives a first overview::
$ make help
test - run developer tests
docs - build documentation
docs-live - autobuild HTML documentation while editing
run - run developer instance
install - developer install (./local)
uninstall - uninstall (./local)
gh-pages - build docs & deploy on gh-pages branch
clean - drop builds and environments
...
.. contents:: Contents
:depth: 2
:local:
:backlinks: entry
.. _makefile setup:
Setup
=====
.. _git stash: https://git-scm.com/docs/git-stash
The main setup is done in the :origin:`Makefile`::
export GIT_URL=https://github.com/asciimoo/searx
export SEARX_URL=https://searx.me
export DOCS_URL=https://asciimoo.github.io/searx
.. sidebar:: fork & upstream
Commit changes in your (local) branch, fork or whatever, but do not push them
upstream / `git stash`_ is your friend.
:GIT_URL: Changes this, to point to your searx fork.
:SEARX_URL: Changes this, to point to your searx instance.
:DOCS_URL: If you host your own (branded) documentation, change this URL.
.. _make pyenv:
Python environment
==================
.. sidebar:: activate environment
``source ./local/py3/bin/activate``
With Makefile we do no longer need to build up the virualenv manually (as
described in the :ref:`devquickstart` guide). Jump into your git working tree
and release a ``make pyenv``:
.. code:: sh
$ cd ~/searx-clone
$ make pyenv
PYENV usage: source ./local/py3/bin/activate
...
With target ``pyenv`` a development environment (aka virtualenv) was build up in
``./local/py3/``. To make a *developer install** of searx (:origin:`setup.py`)
into this environment make target ``install``
.. code:: sh
$ make install
PYENV usage: source ./local/py3/bin/activate
PYENV using virtualenv from ./local/py3
PYENV install .
You have never to think about intermediate targets like ``pyenv`` or
``install``, the ``Makefile`` chains them as requisites. Just run your main
target.
.. sidebar:: drop environment
To get rid of the existing environment before re-build use :ref:`clean target
<make clean>` first.
If you think, something goes wrong with your ./local environment or you change
the :origin:`setup.py` file (or the requirements listed in
:origin:`requirements-dev.txt` and :origin:`requirements.txt`), you have to call
:ref:`make clean`.
.. _make run:
``make run``
============
To get up a running a developer instance simply call ``make run``. This enables
*debug* option in :origin:`searx/settings.yml`, starts ``./searx/webapp.py``
instance, disables *debug* option and opens the site (xdg-open):
.. code:: sh
$ make run
PYENV usage: source ./local/py3/bin/activate
PYENV install .
./local/py3/bin/python ./searx/webapp.py
...
INFO:werkzeug: * Running on http://127.0.0.1:8888/ (Press CTRL+C to quit)
...
.. _make clean:
``make clean``
==============
Drop all intermediate files, all builds, but keep sources untouched. Includes
target ``pyclean`` which drops ./local environment. Before calling ``make
clean`` stop all processes using :ref:`make pyenv`.
.. code:: sh
$ make clean
CLEAN pyclean
CLEAN clean
.. _make docs:
``make docs docs-live docs-clean``
==================================
We describe the usage of the ``doc*`` targets in the :ref:`How to contribute /
Documentation <contrib docs>` section. If you want to edit the documentation
read our :ref:`make docs-live` section. If you are working in your own brand,
adjust your :ref:`Makefile setup <makefile setup>`.
.. _make gh-pages:
``make gh-pages``
=================
To deploy on github.io first adjust your :ref:`Makefile setup <makefile
setup>`. For any further read :ref:`deploy on github.io`.
.. _make test:
``make test``
=============
Runs a series of tests: ``test.pep8``, ``test.unit``, ``test.robot`` and does
additional :ref:`pylint checks <make pylint>`. You can run tests selective,
e.g.:
.. code:: sh
$ make test.pep8 test.unit
. ./local/py3/bin/activate; ./manage.sh pep8_check
[!] Running pep8 check
. ./local/py3/bin/activate; ./manage.sh unit_tests
[!] Running unit tests
.. _make pylint:
``make pylint``
===============
.. _Pylint: https://www.pylint.org/
Before commiting its recommend to do some (more) linting. Pylint_ is known as
one of the best source-code, bug and quality checker for the Python programming
language. Pylint_ is not yet a quality gate within our searx project (like
:ref:`test.pep8 <make test>` it is), but Pylint_ can help to improve code
quality anyway. The pylint profile we use at searx project is found in
project's root folder :origin:`.pylintrc`.
Code quality is a ongoing process. Don't try to fix all messages from Pylint,
run Pylint and check if your changed lines are bringing up new messages. If so,
fix it. By this, code quality gets incremental better and if there comes the
day, the linting is balanced out, we might decide to add Pylint as a quality
gate.
``make pybuild``
================
.. _PyPi: https://pypi.org/
.. _twine: https://twine.readthedocs.io/en/latest/
Build Python packages in ``./dist/py``.
.. code:: sh
$ make pybuild
...
BUILD pybuild
running sdist
running egg_info
...
$ ls ./dist/py/
searx-0.15.0-py3-none-any.whl searx-0.15.0.tar.gz
To upload packages to PyPi_, there is also a ``upload-pypi`` target. It needs
twine_ to be installed. Since you are not the owner of :pypi:`searx` you will
never need the latter.
