1 # Setting up Nominatim for Development
3 This chapter gives an overview how to set up Nominatim for developement
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). It has the following additional requirements:
31 * [behave test framework](https://behave.readthedocs.io) >= 1.2.5
32 * [phpunit](https://phpunit.de) >= 7.3
33 * [PHP CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer)
35 The documentation is built with mkdocs:
37 * [mkdocs](https://www.mkdocs.org/) >= 1.1.2
39 ### Installing prerequisites on Ubuntu/Debian
41 Some of the Python packages require the newest version which is not yet
42 available with the current distributions. Therefore it is recommended to
43 install pip to get the newest versions.
45 To install all necessary packages run:
48 sudo apt install php-cgi phpunit php-codesniffer \
49 python3-pip python3-setuptools python3-dev
51 pip3 install --user behave mkdocs
54 The `mkdocs` executable will be located in `.local/bin`. You may have to add
55 this directory to your path, for example by running:
58 echo 'export PATH=~/.local/bin:$PATH' > ~/.profile
61 If your distribution does not have PHPUnit 7.3+, you can install it (as well
62 as CodeSniffer) via composer:
65 sudo apt-get install composer
66 composer global require "squizlabs/php_codesniffer=*"
67 composer global require "phpunit/phpunit=8.*"
70 The binaries are found in `.config/composer/vendor/bin`. You need to add this
74 echo 'export PATH=~/.config/composer/vendor/bin:$PATH' > ~/.profile
80 All tests are located in the `\test` directory.
82 ### Preparing the test database
84 Some of the behavioural test expect a test database to be present. You need at
85 least 2GB RAM and 10GB disk space to create the database.
87 First create a separate directory for the test DB and fetch the test planet
88 data and the Tiger data for South Dakota:
93 wget https://www.nominatim.org/data/test/nominatim-api-testdata.pbf
94 wget -O - https://nominatim.org/data/tiger2018-nominatim-preprocessed.tar.gz | tar xz --wildcards --no-anchored '46*'
97 Configure and build Nominatim in the usual way:
100 cmake $USERNAME/Nominatim
104 Create a minimal test settings file:
108 NOMINATIM_DATABASE_DSN="pgsql:dbname=test_api_nominatim"
109 NOMINATIM_USE_US_TIGER_DATA=yes
110 NOMINATIM_TIGER_DATA_PATH=tiger
111 NOMINATIM_WIKIPEDIA_DATA_PATH=$USERNAME/Nominatim/test/testdb
115 Inspect the file to check that all settings are correct for your local setup.
116 In particular, the wikipedia path should point to the test directory in your
117 Nominatim source directory.
119 Now you can import the test database:
122 dropdb --if-exists test_api_nominatim
123 ./utils/setup.php --all --osm-file nominatim-api-testdb.pbf 2>&1 | tee import.log
124 ./utils/specialphrases.php --wiki-import | psql -d test_api_nominatim 2>&1 | tee -a import.log
125 ./utils/setup.php --import-tiger-data 2>&1 | tee -a import.log
128 ### Running the tests
130 To run all tests just go to the test directory and run make:
137 To skip tests that require the test database, run `make no-test-db` instead.
139 For more information about the structure of the tests and how to change and
140 extend the test suite, see the [Testing chapter](Testing.md).
142 ## Documentation Pages
144 The [Nominatim documentation](https://nominatim.org/release-docs/develop/) is
145 built using the [MkDocs](https://www.mkdocs.org/) static site generation
146 framework. The master branch is automatically deployed every night on
147 [https://nominatim.org/release-docs/develop/](https://nominatim.org/release-docs/develop/)
149 To build the documentation, go to the build directory and run
153 INFO - Cleaning site directory
154 INFO - Building documentation to directory: /home/vagrant/build/site-html
157 This runs `mkdocs build` plus extra transformation of some files and adds
158 symlinks (see `CMakeLists.txt` for the exact steps).
160 Now you can start webserver for local testing
164 [server:296] Serving on http://127.0.0.1:8000
165 [handlers:62] Start watching changes
168 If you develop inside a Vagrant virtual machine, use a port that is forwarded
172 build> mkdocs serve --dev-addr 0.0.0.0:8088
173 [server:296] Serving on http://0.0.0.0:8088
174 [handlers:62] Start watching changes
