How to RegEx Global Variables

[ISI360]

Hi!

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 Enum $MARGIN_SCRIPT_NUMBER = 0, $MARGIN_SCRIPT_ICON, $MARGIN_SCRIPT_FOLD

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

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

 

The returning array should look like this:

$Var1
$Var2
$var3
$Var4
$var5
$Var_String
$Array_Test
$MARGIN_SCRIPT_NUMBER
$MARGIN_SCRIPT_ICON
$MARGIN_SCRIPT_FOLD
$Delim
$Delim1
$hard1
$hard2
$hard3

 

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 $inivar1)

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

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.

Hi,

I have a suggestion but is not perfect:

(?im:^(?=Global|Const|Enum|Static)(?:Global|Static)?\h*(?:Global|Const|Enum|Static)?(?:(?<=Enum)\h+Step\h+[+*-]\h*\d+)?\h*)(\$(?:\w)+)(?:.*?,(?:[\h_\n]*)*(\$(?:\w)+)*)?(?:.*?,(?:[\h_\n]*)*(\$(?:\w)+)*)?

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 Enum $MARGIN_SCRIPT_NUMBER = 0, $MARGIN_SCRIPT_ICON, $MARGIN_SCRIPT_FOLD
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:

(?:.*?,(?:[\h_\n]*)*(\$(?:\w)+)*)?

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.

@Simpel:
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?
