Problem with StringRegExp

6 posts in this topic

Hi!

Here is a code

#include <ButtonConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#Include <GuiEdit.au3>
$Form = GUICreate("", 400, 300, 300, 300)
$Input = GUICtrlCreateInput("Type regex here", 60, 0, 400, 20)
$Edit = GUICtrlCreateEdit("Some text", 0, 20, 400, 280, BitOR($ES_MULTILINE, $WS_VSCROLL))
$Button = GUICtrlCreateButton("Run", 2, 0, 55, 20, 0)

GUISetState(@SW_SHOW)

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $Button
            Dim $Found
            GUICtrlSetState($Edit, $GUI_FOCUS)
            $Text=GUICtrlRead($Edit)
            $Regex=GUICtrlRead($Input)
            
            # HERE IS A PROBLEM
            $Found=StringRegExp($Text, $Regex, 1)
            _GUICtrlEdit_SetSel($Edit, 0, 1)
            
    EndSwitch
Wend

I want to search all matches(global search) in $Edit with regular expressions (in $Input). Than I want to set multiple selection with _GUICtrlEdit_SetSel() to all matches occured. I have two problems:

1) StringRegExp() returns matches(symbols), but I need offsets(numbers) to push it in _GUICtrlEdit_SetSel. How to get array of offsets of all matches?

2) _GUICtrlEdit_SetSel() sets the only one selection. If I tell to set another selection - the previous will be unselected. How to get multiple selection (in several places of $Edit) with this function?

Actually, I wanted to HIGHLIGHT all matches in $Edit that found by regular expression in $Input. If there is another way to do it - please, tell me

If you don't have to use StringRegExp's patternability you can do something like:

#include <Array.au3>

Local $avOffsets = _GetMatchesOffset("this is an isotropy property miss isolated", "is")
If Not @error Then _ArrayDisplay($avOffsets)

Func _GetMatchesOffset($sString, $sFind)
    Local $sOffsets = ""
    Local $iTmp = 0
    
    Do
        $iTmp = StringInStr($sString, $sFind, 0, 1, $iTmp+1)
        If $iTmp Then $sOffsets &= $iTmp & '|'
    Until Not $iTmp
    
    If Not StringLen($sString) Then SetError(1, 0, 0)
    Return SetError(0, 0, StringSplit(StringTrimRight($sOffsets, 1), '|'))
EndFunc

About highlighting the matches, you can use a rich edit control (search the Examples Forum). I don't think you can assume how much to highlight if you allow regular expressions because \d+ can match for 1 to any arbitrary string of digits length.

Thanks! But I have to use StringRegExp...

Maybe you have seen PowerGREP application? All matches catched by regular expressions are highlighted yellow. I want to do the same (by selection or color).

#include <Array.au3>

Local $aMatches = _GetMatchesOffset("#1234ab cd567 efgh8", "\d+")
If IsArray($aMatches) Then _ArrayDisplay($aMatches)

Func _GetMatchesOffset($sString, $sFind)
    Local $re = ObjCreate("VBScript.RegExp")
    Local $oMatches

    $re.Global = 1
    $re.Pattern = $sFind
    $oMatches = $re.Execute($sString)

    If IsObj($oMatches) Then
        Local $avMatches[$oMatches.Count+1][3] = [[$oMatches.Count]]
        
        For $i = 0 To $oMatches.Count-1
            $avMatches[$i+1][0] = $oMatches($i).FirstIndex
            $avMatches[$i+1][1] = $oMatches($i).Length
            $avMatches[$i+1][2] = $oMatches($i).Value
        Next
        
        Return $avMatches
    Else
        Return SetError(1, 0, 0)
    EndIf
EndFunc

Make sure the object is registered before you try to use it. It's by default registered in Windows operation systems, but check anyway.

OK, I did not understand properly, but I'll try it.
