Delete a COMPLETE line/string and Replace

11 posts in this topic

#1 ·  Posted (edited)

I am trying to replace strings, but only manage to change ONE string/line in a file...I would like to do this function, but with about 20 lines that need to be changed in a file

The program basicaly SEEKS for a string, then DLETES the COMPLETE line and OVERWRITE it with a completely new string. How can i make this search for the remainung 19 lines? here is the code --->

#include <file.au3>
#include <Array.au3>

Opt("MustDeclareVars", 1)
Global $_Array , $file, $pref1, $pref2, $_Element, $replace1, $replace2

$file = "all.js"
$pref1 = '"network.http.keep-alive.timeout"' <---FIRST SEARCH
$replace1 = 'pref("network.http.keep-alive.timeout", 90)' <---THIS LINE NEEDS TO REPLACE THE PRIOR
$pref2 = '"network.http.max-connections"'<---SECOND SEARCH
$replace2 = 'pref("network.http.max-connections", 20)'<---THIS LINE NEEDS TO REPLACE THE PRIOR

_FileReadToArray($file, $_Array)
$_Array = _DeleteArrayElementWithStringInstr($_Array,$pref1)
_FileWriteFromArray($file, $_Array, 1)
Exit

Func _DeleteArrayElementWithStringInstr($_Array, $pref1)
    Local $_Item
    For $_Element In $_Array

        If StringInStr($_Element, $pref1) <> 0 Then
            _ArrayDelete($_Array, $_Item)
            _ArrayInsert($_Array, $_Item, $replace1) <---THIS WORKS 100%, BUT I NEED IT TO "LOOP" TO --->$replace2
        Else
            $_Item += 1
        EndIf
    Next
    Return ($_Array)
EndFunc   ;==>_DeleteArrayElementWithStringInstr

MariusN,

Put your to-be-replaced and replacement lines into an array and then loop through it within your function. :unsure:

Let me be truely honest with you Melba23...i know ZILTS about arrays...really. I have tried numourus times but somehow "lack" that bit of knowlege. You cant maybe give me a small "example"? Anything else, but that has nothing to do with THIS paticular code....just so i can get the "hang" of it...please my friend :-(

There's a Array Tutorial in the wiki :unsure:

MariusN,

You really do need to learn about arrays - they are a fundamental part of coding. I was going to recommend the Wiki tutorial myself but I see AdmiralAlkex has already provided the link to it. :unsure:

Here is a short demo of how looping through an array might work for you:

#include <file.au3>
#include <Array.au3>

Opt("MustDeclareVars", 1)
Global $_Array , $file, $pref1, $pref2, $_Element, $replace1, $replace2, $aReplace[4]

$file = "all.js"

; Create the array with the to-be-replaced and replacement lines in alternate elements
$aReplace[0] = '"network.http.keep-alive.timeout"' ;<---FIRST SEARCH - even element
$aReplace[1] = 'pref("network.http.keep-alive.timeout", 90)' ;<---THIS LINE NEEDS TO REPLACE THE PRIOR - odd element
$aReplace[2] = '"network.http.max-connections"' ;<---SECOND SEARCH - even element
$aReplace[3] = 'pref("network.http.max-connections", 20)' ;<---THIS LINE NEEDS TO REPLACE THE PRIOR - odd element

;_FileReadToArray($file, $_Array)
; Simulate the file being read into an array
Global $_Array[3] = [2, '"network.http.keep-alive.timeout"', '"network.http.max-connections"']

; Do the business
$_Array = _DeleteArrayElementWithStringInstr($_Array,$aReplace)

; And show the result
_ArrayDisplay($_Array)
;_FileWriteFromArray($file, $_Array, 1)

Exit

Func _DeleteArrayElementWithStringInstr($_Array, $aReplace)
    Local $iIndex
    ; Loop through the array - Step 2 means that we only look at every second line which are the ones with the to-be-replaced lines
    For $i = 0 To UBound($aReplace) - 1 Step 2
        ; Get the index of a matching line
        $iIndex = _ArraySearch($_Array, $aReplace[$i])
        ; if we found a valid line
        If $iIndex <> -1 Then
            ; Then replace the line with the replacement line from the array
            $_Array[$iIndex] = $aReplace[$i + 1]
        EndIf
    Next
    Return $_Array

EndFunc   ;==>_DeleteArrayElementWithStringInstr

I have deliberately kept it as simple as I can - I would code it with a 2D array myself, but let us walk before we start running! ;)

Does it make sense? Please ask if not. :>

jchd,

Who needs to be a president? The grins on the faces of the 8 cadets I took for their first flights yesterday is enough for me. :unsure:
