Regular Expression PLEASE HELP!

[Sfikes]

$time = "23:20:23"

$hey = StringRegExp($time, '(\w:\w:\w)')

If $hey == 1 Then
   Send("Yes")
EndIf

If $hey == 0 Then
   Send("No")
EndIf

 

So i wanna know if my string has any numbers. To do that i used StringRegExp in order to check if the string was containing any numbers.

So simply i want it to read like this: Any:Any:Any including the ":" but it always returns 0 as a "no match" which must mean that this script doesnt work. Any suggestions?

Sfikes,

Try this:

#include <MsgBoxConstants.au3>

$time = "23:20:23"

$hey = StringRegExp($time, '(\d+:\d+:\d+)')

If $hey = 1 Then
   MsgBox($MB_SYSTEMMODAL, "Result", "Yes")
   Else
   MsgBox($MB_SYSTEMMODAL, "Result", "No")
EndIf

The difference is that I am looking for at least one digit in section - you were looking for only a single digit, letter or underscore.

Thanks alot man! Works like a charm! Could you explain for me what  \d+: means? I really wanna learn it.

Sfikes,

Reading the Help file page for StringRegExp will explain most of the possible parameters. In this case I used:

  Quote

\d  -  Matches any decimal digit

Expand  

in conjunction with:

  Quote

+	-  1 or more

Expand  

So it will match if we have 3 groups of one or more digits separated by colons.

To be really precise, we should really ask for groups of one or two digits which comes out as:

$hey = StringRegExp($time, '(\d{1,2}:\d{1,2}:\d{1,2})')

Try it with various strings and see how it performs.

RegExes are quite tricky to learn (my brain still bleeds when developing a complex pattern) but are well worth the effort - I always recommend this site as a good place to start.

I never understood (or invested not enough time) StringRegExp. I just tested your eample with a fantasy time:

$time = "239:204:23"

and i got also yes.

Sfikes,

Delighted I could help.

In the future, these sites may help you with RegEx as they certainly helped me

http://regexr.com/ - A playground for making RegEx

https://regex101.com/-  Another playground for making RegEx

https://txt2re.com/ - Visually see and extract the data you want

http://regex.inginf.units.it/ - Builds a RegEx based on examples you provide

https://regexone.com/ - Learn RegEx

Note: These sites are not made for specifically for AutoIt coding, but it's much easier than hitting F5 a dozen times to get what you want.

[Melba23]

AutoBert,

Look at the other pattern I posted - that is more precise and only accepts one or two digits per group.

Just a note about the good links provided above: favor regex101.com as it offers the same regexp flavor as Autoit (PCRE). The reference documentation for PCRE implemented in AutoIt is http://www.pcre.org/original/doc/html/ (AutoIt doesn't implement PCRE2, yet).

msgbox(0, '' , AscW(stringleft($time , 1)) > 47 AND AscW(stringleft($time , 1)) < 58  ? "Yup" : "Nope")
