Should include in the test:
Code:
Loop C:\*.BMP,0,1
{
   imageFiles := imageFiles . A_LoopFileLongPath . "`n"
}
Loop C:\*.JPG,0,1
{
   imageFiles := imageFiles . A_LoopFileLongPath . "`n"
}
Loop C:\*.GIF,0,1
{
   imageFiles := imageFiles . A_LoopFileLongPath . "`n"
}
Probably faster, as the system returns only relevant files, instead of getting all files and filtering them after.

Yeah, I was thinking about PhiLhos test.

This test is based upon if..in and regex:
Code:
SetBatchLines, -1
Process, Priority, , R
dir = %A_MyDocuments%\*.*
i = 100

t1 := A_TickCount
Loop, %i% {
   Loop, %dir%, , 1
      If A_LoopFileExt in bmp,jpg,gif
         list = %list%%A_LoopFileFullPath%`n
   list := ""
}

t2 := A_TickCount
Loop, %i% {
   Loop, %dir%, , 1
      If RegExMatch(A_LoopFileExt, "^bmp|jpg|gif$", "i")
         list = %list%%A_LoopFileFullPath%`n
   list := ""
}

t3 := A_TickCount
MsgBox, % "if..in:`t" . t2 - t1 . "`nregex:`t" . t3 - t2

Seems like regex is faster!!1

@Titan: Unbelievable! :shock: I never knew A_LoopFileExt existed! :(

Look like we got superb tool to play with.

I can not get it how RegExp can be faster than any concrete string function, but this just proves that this re implementation is good and optmised.

How to find the number of a particular character/string/whole word present in a string?

My basic need is find the number of delimiters in a string and would like to have a one line solution like:

Code:
;I want to ascertain the number of semi colons and add 1 to
; find the no.of fields
FieldCount := RegEx??("Apples;Bananas;Cherries", ...) + 1


Refer this post: http://www.autohotkey.com/forum/viewtop ... 4194#84194

I would also like to know how the matches can be counted for a substring or a whole word

Please refer this topic : Count instances of a word appears in a file

:?:

Easy: MsgBox, % StrLen(RegExReplace("one; two; three; four", "[^;]", ""))

I believe so.
Indeed, the code is highly optimized. For example, author doesn't hesitate to put similar code several time to avoid adding a test in the loop... And it uses goto when it saves some CPU cycles! :-)
I didn't saw that in PCRE code (but might have skipped it), but some implementations can detect that the RE is plain text. In this case, they just use an optimized Boyer-Moore string search...

Goyyah, I made a variant of the SplitPath functions, published in the other topic. They might not please you, as they don't use simple assignment, but I felt I had to test this possibility.
It seems latest beta (options in regex) broke the multiline (extended) REs, I will report that.

To answer your latest request is easy, Chris provided a OutputVarCount to the RegExReplace function:
Code:
str = Apples;Bananas;Cherries
RegExReplace(str, ";", "", count)
FieldCount := count + 1
MsgBox % FieldCount

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

Thanks for the elaborate posting!
BTW, R: How to emulate StringSplit? should be R: How to emulate SplitPath?, I guess!
I am posting here because I do not want to mess that topic.
I would like to see that topic become sticky someday! :)

I get blank values! :roll:

Works fine! Thanks!
How do I count "e;" from that string?

:)

That's quite tricky - it's like doing a StringReplace (All). One way is to: StrLen(RegExReplace("one; two; three; four" . " ", ".*?(?:(?<=e;)(.)|$)", "$1")) but it requires at least one character at the end of the string to catch ending delimiters.

Oh! I did not guess that would be tough. Many thanks! :D

Sorry, I don't understand. Do you mean RegExReplace(str, "e;", "", count)?
