Zugg Software :: View topic - [2.26] Dangerous tab expansion of aliases at the command line.

Posted: Thu Jun 12, 2008 2:12 am

I like being able to tab complete text from the window and I use it a lot. However there is a very dangerous aspect of this in that Cmud will expand aliases as well if you type an alias and hit tab.

I have a ton of aliases and many of them are huge. So what happens from time to time is that I accidentally type the name of an alias that I actually wanted expanded to a word from the Mud and it expands to the full text of my huge alias. This can cause a lot of unpredictable results to happen especially if I accidentally press enter and execute it along with a prefix of whatever else I had in my command line at the time. I've actually crashed Cmud a few times when I've hit a particularly long alias.

Would it be possible to alter the behavior of the tab expansion so that this type of alias expansion couldn't happen by accident?

Hmm, excellent point. I use tab completion all the time myself too, but my aliases are not named anything that normally expands, so I don't get this problem myself. But I can see where this would be a big issue and could really ruin the usefulness of the tab expansion of MUD text. Although I've never seen a case of this crash CMUD, so send me specifics if you can reproduce that.

But I'll add an option to turn off alias tab expansion. Maybe even in 2.27.

The worst ones I have no idea what they were because I crashed, but I'll keep an eye out for you and try a few to see which may have caused it.

Thanks for adding that option!
