Setting up Nominatim for Development
This chapter gives an overview how to set up Nominatim for developement and how to run tests.
Important
This guide assumes that you develop under the latest version of Ubuntu. You can of course also use your favourite distribution. You just might have to adapt the commands below slightly, in particular the commands for installing additional software.
Installing Nominatim
The first step is to install Nominatim itself. Please follow the installation instructions in the Admin section. You don't need to set up a webserver for development, the webserver that is included with PHP is sufficient.
If you want to run Nominatim in a VM via Vagrant, use the default ubuntu
setup.
Vagrant's libvirt provider runs out-of-the-box under Ubuntu. You also need to
install an NFS daemon to enable directory sharing between host and guest. The
following packages should get you started:
sudo apt install vagrant vagrant-libvirt libvirt-daemon nfs-kernel-server
Prerequisites for testing and documentation
The Nominatim test suite consists of behavioural tests (using behave) and unit tests (using PHPUnit for PHP code and pytest for Python code). It has the following additional requirements:
- behave test framework >= 1.2.5
- phpunit >= 7.3
- PHP CodeSniffer
- Pylint (2.6.0 is used for the CI)
- pytest
The documentation is built with mkdocs:
- mkdocs >= 1.1.2
Installing prerequisites on Ubuntu/Debian
Some of the Python packages require the newest version which is not yet available with the current distributions. Therefore it is recommended to install pip to get the newest versions.
To install all necessary packages run:
sudo apt install php-cgi phpunit php-codesniffer \
python3-pip python3-setuptools python3-dev pylint
pip3 install --user behave mkdocs pytest
The mkdocs
executable will be located in .local/bin
. You may have to add
this directory to your path, for example by running:
echo 'export PATH=~/.local/bin:$PATH' > ~/.profile
If your distribution does not have PHPUnit 7.3+, you can install it (as well as CodeSniffer) via composer:
sudo apt-get install composer
composer global require "squizlabs/php_codesniffer=*"
composer global require "phpunit/phpunit=8.*"
The binaries are found in .config/composer/vendor/bin
. You need to add this
to your PATH as well:
echo 'export PATH=~/.config/composer/vendor/bin:$PATH' > ~/.profile
Executing Tests
All tests are located in the /test
directory.
To run all tests just go to the build directory and run make:
cd build
make test
For more information about the structure of the tests and how to change and extend the test suite, see the Testing chapter.
Documentation Pages
The Nominatim documentation is built using the MkDocs static site generation framework. The master branch is automatically deployed every night on https://nominatim.org/release-docs/develop/
To build the documentation, go to the build directory and run
make doc
INFO - Cleaning site directory
INFO - Building documentation to directory: /home/vagrant/build/site-html
This runs mkdocs build
plus extra transformation of some files and adds
symlinks (see CMakeLists.txt
for the exact steps).
Now you can start webserver for local testing
build> mkdocs serve
[server:296] Serving on http://127.0.0.1:8000
[handlers:62] Start watching changes
If you develop inside a Vagrant virtual machine, use a port that is forwarded to your host:
build> mkdocs serve --dev-addr 0.0.0.0:8088
[server:296] Serving on http://0.0.0.0:8088
[handlers:62] Start watching changes
