How to RegEx Global Variables

5 posts in this topic

#1 ·  Posted (edited)


I need a little bit help from some RegEx experts please:
I would make my ISN AutoIt Studio faster when generating the scripttree. And what would be better to do this via regex?

Problem is i am not really good at this regex stuff. So maybe someone could help me here.

The challange is to get all Global Variables from a script via RegEx in a Array.
Here is a example script with some tests:

Global $Var1 = 1234 

Local $Local_Var = 1234

$Ignore_me_too = 1234

Global $Var2 = 1234, $var3 = 1242

Global $ahIcons[30], $ahLabels[30]

Global Const $Var4 = iniread($inivar1,"jj","jj","") , $var5= iniread($inivar2,"jj","jj","")

Global $Var_String = "was"

Global $Array_Test[16] = [1,15,16,0,31,15,25,15,25,30,8,30,8,15,1,15]


Global Const $Delim = '\', $Delim1 = '|'

Global $hard1 = "a", _
$hard2 = "b", _ 
$hard3 = "c"


The returning array should look like this:



I already made some success with a expression i found in the SciTE Jump Tool:  (\$\w+)(?:[\h\[.=+*/^,)\-])?
This nearly returns the perfect results. But it does not check if it´s a global variable (with the const and enum options) and also returns variables in commands (for example

I also found this regex: (?im:^(?=Global|Const|Enum|Static)(?:Global)?\h*(?:Const|Enum|Static)?(?:(?<=Enum)\h+Step\h+[+*-]\d+)?\h*)([^\r\n .\=]+)
This returns also usefull results...but trying to understand this explodes my head :D

Maybe someone can help me here?
Thanks in advance! ;);)

Albeit not impossible, you'd have to embark a complete AutoIt grammar parser in pure regexp to be able to process arbitrary code and correctly extract globals.

This wonderful site allows debugging and testing regular expressions (many flavors available). An absolute must have in your bookmarks.

I have a suggestion but is not perfect:


I tested it with this:

Global $Var1 = 1234
Global $Test
global $1we, $dgg,$errzuu
Local $Local_Var = 1234
$Ignore_me_too = 1234
Global $Var2 = 1234, $var3 = 1242
Global $ahIcons[30], $ahLabels[30]
Global Const $Var4 = iniread($inivar1,"jj","jj","") , $var5= iniread($inivar2,"jj","jj","")
Global $Var_String = "was"
Global $Array_Test[16] = [1,15,16,0,31,15,25,15,25,30,8,30,8,15,1,15]
Global Const $Delim = '\', $Delim1 = '|'
Global $hard1 = "a", _
$hard2 = "b", _ 
$hard3 = "c"
Static global $rest
global static $test
Global Enum STEP + 2 $eVariant1 = 1, $eVariant2, $eVariant3 = 5, $eVariant4
static local $test
local static $dfgt

If you try this you may see it will not catch $eVariant4. For every variable more you need this append to regex:


That‘s not that perfect as I wanted but I didn’t get it working to „loop“. I thought change ? with * but then you catch only the last one and not the matches in between. But maybe some other get it working more perfect.

Just an FYI, unless $Local_Var is in a function, it's still a global variable regardless of what you use to declare it in the Global scope.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Thanks, looks very interesting!

Would it be an option to first strip the values of the variables? (They are not needed)

So that

Global Const $Var4 = iniread($inivar1,"jj","jj","") , $var5= iniread($inivar2,"jj","jj","")
Global Enum STEP + 2 $eVariant1 = 1, $eVariant2, $eVariant3 = 5, $eVariant4
Global Const $Delim = '\', $Delim1 = '|'

becomes to

Global Const $Var4, $var5
Global Enum STEP + 2 $eVariant1, $eVariant2, $eVariant3, $eVariant4
Global Const $Delim, $Delim1

Would this then be easier to regex? If yes, have you a idea how to strip this stuff? :P

      Can anyone tell me why this isn't working?..
      #include <array.au3> $regexp = StringRegExp("test 'a b c'", "'([^']|'')*'|\S+", 3) _ArrayDisplay($regexp) trying to split this "test 'a b c'  'some other '' test'' ...'" into:
      0: test
      1: 'a b c'
      2: ...
      but it gives me:
      0: test
      1: c

      Hi guys,
      I am pretty bad with regex, and am having some trouble trying to come up with an expression for a certain type of string. Basically I want to be able to tell if a string is of the format:
      Where the A's are any letter from A-Z and the #'s are any digit from 0-9.
      I've been playing around with a regex tester online for a while but I can't really seem to grasp the concept very well. Could anyone give me any tips?
      This isn't exactly an AutoIt specific question which is why I didn't post it in General Help & Support.

      I have a file (see attached file) with a string all line and this problem on here is I want to separate all $00:, $03:, $10:, $20:, $25:, $30:, $40:, $45:, $110:, $115:, $120: and $T. It's mean that each $ with value start a new line ( a new paragraph). I tried with Regular Expression in notepad++ ex:
      Find ($00:, $01:, $03: and so on) with regex (\$)([0-9]+): and replace is \r\n\1\2 (I think \r\n is @CRLF (not sure :() ) Find $T with regex (\$T)(.*?)(\$T) and replace is \1\2\r\n\3 When I try these regex to replace in notepad on StringRegexReplace the results is incorrect . I have read some example simple about regex. Please advise me how to do that with some example on autoit . The result will be in attached photo. Thanks

      Hello, i need to validate a string can be different things. I just need a True - False return value, no groups or things like that. It will be always one line at time to be processed by StringRegEx
      02:52 XX|String
      13:52~SUN, MON, TUE, WED, THU, FRI, SAT|String
      02:52 XX~SUN, MON, FRI|String
      22/04/2017 13:52|String
      22/04/2017 02:52 YY|String
      Not Valid
      22/04/2017 13:52~Dom|String
      I need to validate until and inclusively the | after that i don't care
      The XX and YY value are two $sVariable from my script
      SUN, MON, TUE, WED, THU, FRI, SAT are fixed value, the can be mixed but always in the same order like
      SUN, TUE, WED
      SUN, SAT 
      The time can be 12 or 24 hours, the date is always in the same format DD/MM/YYYY. If there is a date can't be a day after that ( see not valid )
      Well i think is all
      Sorry if i don't provide a working code, regex is too way complex.

      I need to list only the folders that has a name composed of numbers only.
      How do I do this?
      OBS: I just posted the relevant content to the folder.
      Global $path = "G:\jobs\" For $i = 1 To $aArray[0] Local $search = FileFindFirstFile($path & $aArray[$i] & "\[0-9]" ) I tried with "\*.*" and it returns me the expected result, but the other doesn't.
