PING! PONG!

[vakkotaur]

When I used mIRC for IRC, I had a list of pongs (replies to pings) that were somewhat randomly chosen to send back to whoever pinged me. Then I switched to x-chat and needed a script to the same thing. I didn't snag one from anyone, nor did I write one... until recently.

I've been playing with Python a bit and this past week found out how to open, read, and close files with Python. After a while I had the core of the script done, but needed to make it work with x-chat.

Yesterday evening I started playing with the x-chat python stuff and managed to send commands to x-chat. This morning I managed to get x-chat to load and run a script. With help from jmaynard I managed to get it to be useful.

The result probably isn't ideal, but this is the first bit of working (as in, it has a job and does it and isn't just an example) Python I've written. It uses the same style file as mIRC does: The first line is the number of remaining lines, each of the remaining lines is a possible reply. For anyone desperate enough to use this, remember to change the line with the file location.
