The trashcan where all Undertale trash is
Posted 09 February 2013 - 03:31 PM
I know, this is a forum for CC/lua, but I really have nowhere else to ask this: I am trying to format a string with regexp. I have never used regexp before. What I want is for the first two letters of the string to be capitalized, but all I can find is the anchor for the beginning of a string. How can I select the first two letters of the string, and then capitalize them?

You don't need regex for that.
s = "heLlO TheRe"
s = s:sub(1, 2):upper() .. s:sub(3):lower()

Um. Actually, I do need regex. It's kind of a scripting thing on an application. Specifically, I'm using Pesterchum and trying to implement a quirk. The quirk system, along with several other preinstalled choices, has a quirk option for regex scripting.
Regex: *text box*
Replace with: *text box*
It is supposed to work like this:
CB: HEy dude. HOw's it going? STuff like that. LIke someone holding the shift key a bit too long.

See? Regexp is mandatory.

I'm not sure how to turn something uppercase with regex alone, but I do know how to capture/reuse matches. It's $1, $2, $3 etc. like %1, %2, %3 etc. in lua.
So replacing "l" with "$1…" in the string "Hello World!" would produce "Hel…l…o Worl…d!"

Just took a look at pesterchum and this seems to be what you want:
Regexp: \b(\w\w|\w)
Replace: upper(\1)
And if you want only the first 2 letters of a word capitilized then you need this one aswell but applied before the above one
Regexp: (.)
Replace: lower(\1)

Well, I didn't need the second one, but otherwise it worked well. Except for one thing:
CB: IT TYped LIke THis
CB: NOt like this.
It capitalized the first two letters of every word, not sentence.

Hello? This still hasn't been resolved.

Doing the first 2 letters of every line is pretty simple the regexp would just be
Regexp: ^(\w\w|\w)
Replace: upper(\1)
But matching multiple sentences on one line not so much.

To match the first two letters of every sentence, then lowercase the rest:
Match: (\w\w)(.*?\.)
Replace: upper(\1)lower(\2)
For just the two letters, without lowercasing the rest:
Match: (\w\w).*?\.
Replace: upper(\1)lower(\2)
Untested, so I'm not completely sure if this'll work.

Thank you! This works perfectly :D/>
Given that it's a chat client, I probably won't really be having more than one sentence per line. So it won't be a problem! :)/>

I find this site is really helpful when I'm trying to thrash out regexes
