I have no idea what could cause these messages, but I was getting messages printed to the screen in cyan like

ERROR: unary operator requires two arguments
ERROR: function unmatched paranthesis something something

That's not how normal Lua errors are displayed, so I was very confused. I was running simple code like

functon lol (msg) error(msg) end

or

for k in pairs(_G) do print(k) end

And these errors were appearing.

Very similar (in style) to my case http://forums.zuggsoft.com/forums/viewtopic.php?t=28400 - double ERROR messages and wrong number of arguments mention, appeared first in 2.04. Think this is related to these threading issues Zugg trying to fix now. Will wait till 2.05 before report any further.

When you get an error message displayed in the MUD window like that, it means that an alias (or other script) that was executing in the background had an error in the CMUD execution module. Since this can happen many threads deep into a complex script, CMUD doesn't abort and raise a normal exception, but instead just displays the error to the screen. So, these errors should normally only occur when using zScript stuff. Make sure your script was marked as "Lua" and not "zScript".

This is actually totally different than the error reported by Arde, since they don't have anything to do with Lua.

It wasn't an alias, it was on the command line, and I was very much in Lua mode (or it seemed that way, at least) when it happened.

An error is different, but I told about how the error report look like. Since its not a Lua error msg, it is the message from CMUD itself. And these messages from CMUD I see in CMUD since 2.04.
If you say "it is different" - ok, it is different. Let's wait till 2.05 and see. Smile

Hmm, you definitely shouldn't be getting those kind of errors when using the Lua command line. But, I just typed:
