See my example a couple posts up.

Oh! I did not guess that would be tough.

I'm no regex expert. I'm sure it's possible to avoid the extra chars with a conditional and an atomic grouped lookaround... but I'll leave that to PhiLho, majkinetor, JSLover and the other regex nerds Razz

I tested the above with the latest beta, did you got it? I can't remember if this count of replaces was in the previous version.

Where do I get it? Rolling Eyes

I want to count e; in "One;Two;Three;Four;Five",
the result will be 2!

This will return count in my version: v := RegExMatch(var, "e") _________________

You guessed wrong... I downloaded it from forum

Well...it seems that above doesn't work well...

Code:

var := "mone;y toke;ne"
v := RegExMatch(var, "e;")
msgbox %v%

Returns 4

RegExMatch (var, "o") returns 2
RegExMatch(var, "e;y") returns 4 ...
RegExMatch(var, "`;y") returns 5 ?

I don't get this really as

Quote:

var := "mone;y toke;ne"
v := RegExReplace(var, "e;", "", count)
msgbox %count%

Returns 2

For now, goyah, you can use RegExReplace(var, "e;", "e;", count)

Dear PhiLho, Smile

Code:

str = Recommended for new scripts due to its superior speed and reliability.
RegExReplace(str, "\w+", "", count)
MsgBox % count

Thats cool too.. but I meant searching a whole word.. For example:

"The Theft Broke-in Through The Window"

I want to search for "the" ( case insensitive ) and result should be 2 .. not 3

Smile

Same address as the previous one: Regular Expressions (RegEx) for AutoHotkey

Yes, that's what I gave (again, lastest version!). I was lost because Titan provided a complex expression...

Uh, no, in both versions, it returns the found position...

Ah, counting a given word. No problem:

Code:

str = The Theft Broke-in Through The Window
RegExReplace(str, "i)\bthe\b", "", count)
msgbox %count%

\b is "word bound", working also on string ends.

RegEx is very interesting!

Oh I never knew RegExReplace had that feature. I also didn't know how to convert ++/e;/.exec('one; two; three; four').length; javascript to ahk, hence my long-winded approach. Goyyah (and Laszlo) prefer one-line solutions so: Asc(RegExReplace("one; two; three; four", "e;", "", c)) * 0 + c

Definitely yes!

Code:

str = The Theft Broke-in Through The Window of The House
MsgBox, % Asc(RegExReplace(str,"i)\bthe\b", "", count)) * 0 + count

Many thanks for coming up with that technique! Readable or not, if it is going to be inside my function, I prefer one-liners.

Smile

Can a string be converted into Upper/Lower/Sentence case with RegExReplace? Forgive me if it is a stupid request! _________________

I don't think it's possible, what's wrong with StringLower/StringUpper anyway?
