Could anyone provide a list of acceptable patterns and wildcards for use with fs.find? I'm making a pure-Lua implementation of it for one of my projects. All I could find so far was the '*' wildcard.

I don't think there are any others since none are documented on the wiki besides from the asterisk. I have the source in front of me.. but I don't know how regexes work (should I be ashamed?). And I'm assuming it wouldn't be okay to post the source here for someone that understands them to decipher, so I won't.

Well I just tested and ? seems to work too…
fs.find("rom/????/gps") finds rom/apis/gps and rom/help/gps…

Pure guessing here but it would make sense
* - one or more wildcards
? - one wildcard

Wonder if there are other unknown ones.

Those two are correct, but I'm still trying to see if there are others.

'.' seems to do the same as '?'.
EDIT: There's a Lua implementation of the function in Gamax's version of cclite here on line 687. '?', '.' and '*' seem to be all of them.

Could someone try '-'? On my iPad right now.

I've created three files in root named '1', '2' and '3'.

fs.find("[1-3]")

seems to find all of them.

So I guess it's using string patterns…

Try the same three files and fs.find("%d") please? :P/>

Yes, it seems to find all three of them.

For whatever reason none of them work for me. Only the asterisk (*). But if I'm correct I would say here is a list of what should work.

That's probably the case since Pattern.compile is what the source code uses.

Anyone knows why nothing works for me? I'm using CC 1.62.

They only seem to work on cclite. I can't use them on CC1.62 either.

Interesting. I'll test more out later.

Ah, well that would explain everything :D/>. I thought it was something wrong with my Java. That's why I use MC with real CC to test things. cclite's implementation uses regular Lua's string matching capabilities, so any Lua patterns would work.

Alright, in further testing it appears that in regular CC, only the * wildcard is accepted. Others may be available in emulators.
