Strangeness when reading value and running regex

6 posts in this topic

I figured I'd have a go at creating a live regex tester, not a big deal right?

Input box for regex, textfield with text to test against, and an output box showing results.

But here's where it gets weird.

If I run: $resultHolder = StringRegExp( "Edit 1", "Edit", 0)

I get 1, there's a match.

But if I do: $resultHolder = StringRegExp( "Edit 1", $tempText, 0)

Where tempText is Edit, I get 0, no matches..

I can't figure it out.

Anyone run into something similar?

My *guess* is that there are extra characters ending up in the variable somehow, which throws off the regex match-

No reproducer script?

Without one, you force us to write one, then guess how you are doing things.

This would be as much work as I'd be willing to put into debugging for you with what you've provided, but it works:

Global $gs_testVar = "Edit"
Global $gb_retVal = StringRegExp("Edit 1", $gs_testVar)
ConsoleWrite($gb_retVal & @CRLF)

Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer.

Allright, let's see if this works..

-edit- reading this over, I found my misteak, I flipped the StringRegExp...

#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <Date.au3>

#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("Form1", 615, 438, 260, 180)
$regIn = GUICtrlCreateInput("Input1", 10, 30, 591, 21)
$textToCheck = GUICtrlCreateEdit("", 10, 80, 265, 349)
GUICtrlSetData(-1, "Edit1")
$matches = GUICtrlCreateEdit("", 290, 80, 315, 169)
GUICtrlSetData(-1, "Edit2")
$Label1 = GUICtrlCreateLabel("Regex", 20, 10, 35, 17)
$Label2 = GUICtrlCreateLabel("Text", 20, 60, 25, 17)
$Label3 = GUICtrlCreateLabel("Matches", 300, 60, 45, 17)
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

Global $tempText = ''
Global $resultHolder = ''
Global $regToRun = ''

While 1
   $nMsg = GUIGetMsg()
   Switch $nMsg
      Case $GUI_EVENT_CLOSE
         Exit

   EndSwitch

   $regToRun = GUICtrlRead($regIn)
   $tempText = GUICtrlRead($textToCheck)

   $resultHolder = StringRegExp( "Edit 1", $tempText, 0)
   GUICtrlSetData( $matches, $resultHolder & ' - ' & _NowTime())

   Sleep(100)
WEnd

@ MarcusFernstrom: have you looked at the Regex script in the help file? Look for "Tutorial - Regular Expression" and at the bottom of the page there is a button (open StringRegExpGUI.au3) to open the Regex script in SciTE.

Yes I found my error the other night (As reflected in the edit, last night) I had simply flipped the regex and string in StringRegExp.

I actually finished up version 0.1 of this and put up in Example Scripts
