ways to pass @error (with array)

5 posts in this topic

Thanks to the help with StringRegExp from Melba23 I have got a function now

Func _LogFile_RegEx_Filter($string)
    $found = StringRegExp($string, ":\s(\d{1,3}\.\d{1,2}°[NSEW])", 3)
    Switch $found
        Case @error = 1
            ConsoleWrite("DBG: Array is invalid" & @CRLF)
                        $found[0] = "ERROR"
        Case @error = 2
            ConsoleWrite("DBG: Bad pattern. Array is invalid" & @CRLF)
                        $found[1] = "ERROR"
    EndSwitch

    return $found
EndFunc

I can use it fine like this

Local $mutate = _LogFile_RegEx_Filter($data)

ConsoleWrite("LAT:[" & $mutate[0] & "] LON: [" & $mutate[1] & "]")

until I feed in string which does not give a match and should error out - trying for all possible scenarios)

Instead of getting text on a console with  LAT:[ERROR] LON:[ERROR] script crashes with a

 

==> Subscript used on non-accessible variable.:

$found[0] = "ERROR"
$found^ ERROR
->20:45:50 AutoIt3.exe ended.rc:1

 

how to fix it? So that some unexpected line in log file would not make whole thing come crashing down

Are you going to test against $found, or are you going to test against @error, because you're mixing the 2 in your switch statement.

First, you can't use an array in a Switch like that. Second, if there's an error then $found will not be an array so you can't use it like you're doing later.

shaqan,

I would code the function like this so that an array is always returned: ;)

#include <Array.au3>

$sString = "2014-03-02 14:12:27 | Current location: Unknown, Lat: 58.88°N, Lon: 94.39°E, Altitude: 105 m"
$aRet = _LogFile_RegEx_Filter($sString)
_ArrayDisplay($aRet, "", Default, 8)

$sString = "blah"
$aRet = _LogFile_RegEx_Filter($sString)
_ArrayDisplay($aRet, "", Default, 8)

Func _LogFile_RegEx_Filter($string)

    ; Run the SRE - if it works the array is created
    Local $aFound = StringRegExp($string, ":\s(\d{1,3}\.\d{1,2}°[NSEW])", 3)
    ; Switch on the @error returned
    Switch @error
        Case 1 ; Do use the correct syntax - look in the Help file to check
            ConsoleWrite("DBG: Array is invalid" & @CRLF)
            ; Declare the array as an error
            Local $aFound[2] = ["ERROR", 1]
        Case 2
            ConsoleWrite("DBG: Bad pattern. Array is invalid" & @CRLF)
            Local $aFound[2] = ["ERROR", 2]
    EndSwitch
    ; And return whatever array was created
    Return $aFound

EndFunc
All clear? Please ask if not. :)

aha, thanks. seems to work.

Local $aFound[2] = ["ERROR", 1]

that ,1] puzzled me until I realized you put it there to mark "error code" and to fill second slot in the array.
