I have an old text file I made while still using zMUD many years ago, and a few aliases that allowed me to search that text file and return the result I was looking for, but I can't get it to work properly in CMUD. I've narrowed it down to the %grep I think, but I can't figure out what's wrong with it.

The file is a long list of mobs in my MUD. The alias is as follows:

Take the %-1 out of quotes. In cmud, when you put something in quotes, it means treat it as a literal string, and thus it's not being expanded. That should mean it's searching the file for the actual sequence of characters %-1, so I'm not sure why it's returning the entire file (unless you have that on every line), but regardless, %grep(2, %-1) should do what you want.

Tried that already. The %grep(1,"string") still has the quotes shown in the helpfiles, but that could be a remnant of zMUD, but I thought the same thing so I tried that first. No luck unfortunately. :/

Well yes, because in that example it's searching for an actual string. In your case, you're not - you're searching for the contents of a variable, and you want that variable to expand. I don't know why it won't work, I'm afraid...

After looking at it more closely, it appears that the %grep may not be the problem - I tested it with a new alias by itself, and it worked as intended. Could is possibly be the

Well, is the mobsearch_matches variable ever empty? You said above that the %grep is always returning the entire file, if that's the case then it would make sense that the else part would always be run...

It is redefined at the beginning of the alias. Deleting the variable and then entering the alias to recreate it ends with the same result - the entire file (all 900-something lines/mobs) is matched and saved in the variable, and then output (limited only by the @mobsearch_numresult variable, to prevent my window from being spammed with all 900-something lines. What I can't figure out is why the entire file is being matched, regardless of what I search for. For example, if I search for

Well, I copied that small part of your file into a new text file, and saved it in my session directory as script_moblist.txt. I created a new alias, mobsearch, and copy/pasted in your code from the first post (removed the quotes around the %-1 in the %grep). I created a new variable called mobsearch_numresult, and gave it a value of 10. Then I typed mobsearch 15 headed on the command line, and got this:

So strange. I renamed the old alias "old_mobsearch", made a new one named "mobsearch", then copied and pasted the exact contents of the old alias in to the new one, and it works just as it used to - the first time. Any repeated attempts make the same result, matching the whole file.

Did you try testing it on a brand new session? I can't get your code to fail, so I think it might be something else interfering with it. For example, is it possible you have a duplicate mobsearch_matches variable? The grep could be storing the correct results in one mobsearch_matches, then the contents of the other mobsearch_matches, which happens to contain the entire file, are displayed. Running it on a clean session with no other settings but that one alias installed would help rule out problems like that.
