Python+twisted-based development framework for interactive installations

Sparked

Like the Twisted asynchronous network framework, Sparked is a python library and an application runner in one. Some of its features follow here:

• Robust startup and restart of the program; if it crashes, it's started again.

• Logging: keeps a rotated logfile for debugging purposes.

• Pidfile management for making sure your app starts only once.

• A GUI status window (based on GTK) for monitoring the state of the application and the state of the system (network, power supply, ...). Easy to add your own monitors.

• Fullscreen graphics display for creating interactive displays, based on the clutter library.

• Eventing system for broadcasting messages between sparked components.

• A state machine for guiding the application through different states, with callback functions.

• Possibility to run the sparked application as a twisted plugin for server applications, including a generic init.d startup script.

• Plug-and-play support for hardware: automatically start and stop parts of the program when hardware is added or removed.

sparked's Issues

Support for serial RFID reader protocols

• sonmicro readers
• stronglink SLxxx readers

Logrotate does not work correctly

When starting a deamon which was packaged using the debianize script, the logrotate does not work, it generates 0-sizes log files.

Daemonize option to sparkd executable

Although it is already possible to create a daemonizing sparked server, this is currently only done through the sparked-init script:
ln -s /usr/share/sparked/sparked-init /etc/init.d/your-sparked-plugin-name

It should be supported through the regular sparkd executable as well (sparkd -d app.py)
