# pyosmium
Provides Python bindings for the [Libosmium](https://github.com/osmcode/libosmium) C++
library, a library for working with OpenStreetMap data in a fast and flexible
manner.
[![Travis Build Status](https://api.travis-ci.org/osmcode/pyosmium.svg)](http://travis-ci.org/osmcode/pyosmium)

## Dependencies
Python >= 2.7 is supported but a version >= 3.3 is strongly recommended.
Other requirements are:
* Python setuptools
* [Boost.Python](http://www.boost.org/doc/libs/1_56_0/libs/python/doc/index.html)
* protozero, expat, libz, libbz2 and Boost iterator
(see also [Libosmium dependencies](http://osmcode.org/libosmium/manual.html#dependencies))
* a recent C++ compiler (Clang 3.4+, GCC 4.8+)
You have to compile with the same compiler version that Python is compiled with on
your system, otherwise it might not work.
### Debian/Ubuntu
On Debian/Ubuntu systems all required dependencies can be installed with:
sudo apt-get install build-essential libboost-python-dev \
libexpat1-dev zlib1g-dev libbz2-dev
### Homebrew (OS X)
On OS x Boost.Python needs to be installed with
`brew install boost-python` or `brew install boost-python3`
depending on which Python version you want to use. You can also (re)install
both.
## Installation
### Using Pip
The recommended way to install pyosmium is via pip:
pip install osmium
There are also experimental binary wheels for Windows available.
### Compiling from Source
When compiling from source, you need to get the latest libosmium version
first. It is recommended to put it next to the pyosmium source. The setup
script uses per default either a globally installed libosmium or
looks for the source in `../libosmium`. You can set a custom location with
`LIBOSMIUM_PREFIX`.
To use a custom boost installation, set `BOOST_PREFIX`.
To compile the bindings, run
python setup.py build
To compile and install the bindings, run
python setup.py install --user
to install only for your user, or
python setup.py install
to install globally.
## Examples
The `example` directory contains small examples on how to use the library.
They are mostly ports of the examples in Libosmium and osmium-contrib.
## Testing
There is a small test suite in the test directory. This provides regression
test for the python bindings, it is not meant to be a test suite for Libosmium.
You'll need the Python `nose` module. On Debian/Ubuntu install the package
`python-nose`. For Python2 `mock` is required as well (package `python-mock`).
The suite can be run with:
cd test
python run_tests.py
## Documentation
To build the documentation you need [Sphinx](http://sphinx-doc.org/)
and the [autoprogram extension](https://pythonhosted.org/sphinxcontrib-autoprogram/)
On Debian/Ubuntu install `python-sphinx sphinxcontrib-autoprogram`
or `python3-sphinx python3-sphinxcontrib.autoprogram`.
First compile the bindings as described above and then run:
cd doc
make html
For building the man pages for the tools run:
cd doc
make man
