How to insert a space every two characters?
I would like to split byte strings, for exampl开发者_StackOverflow社区e AAFF10DC
, with spaces, so it becomes AA FF 10 DC
.
How to do this in AutoIt (v3)?
I would like to split byte strings … with spaces …
Example using StringRegExpReplace()
:
Global Const $g_sString = 'AAFF10DC'
Global Const $g_sPattern = '(.{2})'
Global Const $g_sReplace = '$1 '
Global Const $g_sResult = StringRegExpReplace($g_sString, $g_sPattern, $g_sReplace)
ConsoleWrite($g_sResult & @CRLF)
Returns AA FF 10 DC
.
This is sorta ugly, but it works:
$string = "AAFF10DC"
$strArray = StringSplit($string, "") ; No delimiter will separate all chars.
$strResult = ""
If IsEvenNumber($strArray[0]) Then
For $i = 1 to $strArray[0] Step 2
$strResult = $strResult & $strArray[$i] & $strArray[$i+1] & " "
Next
MsgBox(0, "Result", $strResult)
Else
MsgBox(0, "Result", "String does not contain an even number of characters.")
EndIf
Func IsEvenNumber($num)
Return Mod($num, 2) = 0
EndFunc
Global $s_string = "AAFF10DC"
MsgBox(64, "Info", _str_bytesep($s_string))
Func _str_bytesep($s_str, $s_delim = " ")
If Not (Mod(StringLen($s_str), 2) = 0) Then Return SetError(1, 0, "")
Return StringRegExpReplace($s_str, "(..(?!\z))", "$1" & $s_delim & "")
EndFunc
Is just another way to do it. For huge amounts of byte data, I would not suggest using this method.
