User:WindPower/RCNotify.py
About this script
This is a Python script that:
- Fetches the recent changes log every User:WindPower/Template:RCNotifyRefreshRate seconds
- Fetches the TF2 blog to look for updates
- Sends the results back to the IRC bot (#tfwiki on irc.freenode.net), and the bot notifies everyone in the channel about it.
Running this script
- First way: Download Python and run the script as is.
- Download Python and install it if you haven't got it yet.
- Copy the code in the Source section below, and save it in a text file. Give it a .py extension, preferably.
- Open a command prompt or terminal window, and run Python with the script's path as argument.
- On Windows:
C:\Python26\python.exe C:\path\to\script.py - On Unix (Mac/Linux):
python /path/to/script.pt - On Unix (Mac/Linux), you can also type simply
/path/to/script.pyif you set the executable bit on the script file beforehand (chmod +x /path/to/script.py).
- On Windows:
- Second way (Windows only): Download the exe.
