# PyWPS
PyWPS is an implementation of the Web Processing Service standard from
the Open Geospatial Consortium. PyWPS is written in Python.

## License
As of PyWPS 4.0.0, PyWPS is released under an
[MIT](https://en.wikipedia.org/wiki/MIT_License) license
(see [LICENSE.txt](LICENSE.txt)).
## Dependencies
See [requirements.txt](requirements.txt) file
## Install
Install it from GitHub:
```bash
$ git clone https://github.com/geopython/pywps.git
$ cd pywps/
$ pip install .
```
## Run tests
```bash
pip install -r requirements-dev.txt
# run unit tests
python -m pytest tests
# run code coverage
python -m coverage run --source=pywps -m unittest tests
python -m coverage report -m
```
## Quick Guide with Conda
Checkout source from GitHub:
```bash
$ git clone https://github.com/geopython/pywps.git
$ cd pywps/
```
Build conda environment:
```bash
conda env create -f environment.yml
```
Install pywps:
```bash
make install
```
Or the development version:
```bash
make develop
```
Run tests:
```bash
make tests
```
## Run web application
### Example service
Clone the example service after having installed PyWPS:
```bash
git clone git://github.com/geopython/pywps-flask.git pywps-flask
cd pywps-flask
python demo.py
```
Access example service: http://localhost:5000
### Apache configuration
1. Enable WSGI extension
2. Add configuration:
```apache
WSGIDaemonProcess pywps user=user group=group processes=2 threads=5
WSGIScriptAlias /pywps /path/to/www/htdocs/wps/pywps.wsgi
<Directory /path/to/www/htdocs/wps/>
WSGIProcessGroup group
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
</Directory>
```
3. Create wsgi file:
```python
#!/usr/bin/env python3
import sys
sys.path.append('/path/to/src/pywps/')
import pywps
from pywps.app import Service, WPS, Process
def pr1():
"""This is the execute method of the process
"""
pass
application = Service(processes=[Process(pr1)])
```
4. Run via web browser
`http://localhost/pywps/?service=WPS&request=GetCapabilities&version=1.0.0`
5. Run in command line:
```bash
curl 'http://localhost/pywps/?service=WPS&request=GetCapabilities&version=1.0.0'
```
## Issues
On Windows PyWPS does not support multiprocessing which is used when making
requests storing the response document and updating the status to displaying
to the user the progression of a process.
