Because I do not want loosing time staying in sync with main Indi branch development commits, I had to transfer ownership of this work to Indi maintainers.
PYINDI-CLIENT HAS MOVED TO THIS INDI repository. DO NOT USE MY REPO ANY MORE.
| version: | 0.2.7 |
|---|
An INDI Client Python API, auto-generated from the official C++ API using SWIG.
Use pip
pip install pyindi-clientAlternatively download a zip archive (use commits history to get a previous release), extract it and run
python setup.py installThe file setup.cfg contains configuration options (mainly concerning libindi installation path). Edit setup.cfg if you use a libindi version < 1.4.1 (02/2017). The file setup.py searchs for the libindiclient.a library in some predefined directories. If not found, the script fails. Locate this library (try locate lindiclient.a from the command line) and add its path to the libindisearchpaths variable in the setup script.
For the above installation to work, you need to have installed from your distribution repositories the following packages: Python setup tools, Python development files, libindi development files and swig.
On an Ubuntu-like distribution, you may use
apt-get install python-setuptools apt-get install python-dev apt-get install libindi-dev apt-get install swig apt-get install libcfitsio-dev apt-get install libnova-dev
On a Fedora-like distribution, you may use
dnf install python-setuptools dnf install python-devel dnf install libindi-devel dnf install swig dnf install libcfitsio-dev dnf install libnova-dev
In the following simple example, an INDI client class is defined giving the implementation of the pure virtual INDI client functions. This is mandatory. This class is instantiated once, and after defining server host and port in this object, a list of devices together with their properties is printed on the console.
