1 # Setting up Nominatim for Development
3 This chapter gives an overview how to set up Nominatim for development
7 This guide assumes that you develop under the latest version of Ubuntu. You
8 can of course also use your favourite distribution. You just might have to
9 adapt the commands below slightly, in particular the commands for installing
12 ## Installing Nominatim
14 The first step is to install Nominatim itself. Please follow the installation
15 instructions in the [Admin section](../admin/Installation.md). You don't need
16 to set up a webserver for development, the webserver that is included with PHP
19 If you want to run Nominatim in a VM via Vagrant, use the default `ubuntu` setup.
20 Vagrant's libvirt provider runs out-of-the-box under Ubuntu. You also need to
21 install an NFS daemon to enable directory sharing between host and guest. The
22 following packages should get you started:
24 sudo apt install vagrant vagrant-libvirt libvirt-daemon nfs-kernel-server
26 ## Prerequisites for testing and documentation
28 The Nominatim test suite consists of behavioural tests (using behave) and
29 unit tests (using PHPUnit for PHP code and pytest for Python code).
30 It has the following additional requirements:
32 * [behave test framework](https://behave.readthedocs.io) >= 1.2.6
33 * [phpunit](https://phpunit.de) (9.5 is known to work)
34 * [PHP CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer)
35 * [Pylint](https://pylint.org/) (CI always runs the latest version from pip)
36 * [mypy](http://mypy-lang.org/) (plus typing information for external libs)
37 * [Python Typing Extensions](https://github.com/python/typing_extensions) (for Python < 3.9)
38 * [pytest](https://pytest.org)
40 For testing the Python search frontend, you need to install extra dependencies
41 depending on your choice of webserver framework:
43 * [sanic-testing](https://sanic.dev/en/plugins/sanic-testing/getting-started.html) (sanic only)
44 * [httpx](https://www.python-httpx.org/) (starlette only)
45 * [asgi-lifespan](https://github.com/florimondmanca/asgi-lifespan) (starlette only)
47 The documentation is built with mkdocs:
49 * [mkdocs](https://www.mkdocs.org/) >= 1.1.2
50 * [mkdocstrings](https://mkdocstrings.github.io/) >= 0.16
51 * [mkdocstrings-python-legacy](https://mkdocstrings.github.io/python-legacy/)
53 ### Installing prerequisites on Ubuntu/Debian
55 Some of the Python packages require the newest version which is not yet
56 available with the current distributions. Therefore it is recommended to
57 install pip to get the newest versions.
59 To install all necessary packages run:
62 sudo apt install php-cgi phpunit php-codesniffer \
63 python3-pip python3-setuptools python3-dev
65 pip3 install --user behave mkdocs mkdocstrings pytest pylint \
66 mypy types-PyYAML types-jinja2 types-psycopg2 types-psutil \
67 sanic-testing httpx asgi-lifespan
70 The `mkdocs` executable will be located in `.local/bin`. You may have to add
71 this directory to your path, for example by running:
74 echo 'export PATH=~/.local/bin:$PATH' > ~/.profile
77 If your distribution does not have PHPUnit 7.3+, you can install it (as well
78 as CodeSniffer) via composer:
81 sudo apt-get install composer
82 composer global require "squizlabs/php_codesniffer=*"
83 composer global require "phpunit/phpunit=8.*"
86 The binaries are found in `.config/composer/vendor/bin`. You need to add this
90 echo 'export PATH=~/.config/composer/vendor/bin:$PATH' > ~/.profile
96 All tests are located in the `/test` directory.
98 To run all tests just go to the build directory and run make:
105 For more information about the structure of the tests and how to change and
106 extend the test suite, see the [Testing chapter](Testing.md).
108 ## Documentation Pages
110 The [Nominatim documentation](https://nominatim.org/release-docs/develop/) is
111 built using the [MkDocs](https://www.mkdocs.org/) static site generation
112 framework. The master branch is automatically deployed every night on
113 [https://nominatim.org/release-docs/develop/](https://nominatim.org/release-docs/develop/)
115 To build the documentation, go to the build directory and run
119 INFO - Cleaning site directory
120 INFO - Building documentation to directory: /home/vagrant/build/site-html
123 This runs `mkdocs build` plus extra transformation of some files and adds
124 symlinks (see `CMakeLists.txt` for the exact steps).
126 Now you can start webserver for local testing
129 build> make serve-doc
130 [server:296] Serving on http://127.0.0.1:8000
131 [handlers:62] Start watching changes
134 If you develop inside a Vagrant virtual machine, use a port that is forwarded
138 build> PYTHONPATH=$SRCDIR mkdocs serve --dev-addr 0.0.0.0:8088
139 [server:296] Serving on http://0.0.0.0:8088
140 [handlers:62] Start watching changes
