valfar999 Posted May 5, 2014 Share Posted May 5, 2014 Hi, there is this file that have many different variables and values in it in the form of (variable=value) How can I find a variable in that file, and change its value to something different (Similar to sed in Linux)? Ex: File has this variable and value IPADDRESS=10.10.10.10 and the name of the file is net.txt How can I change IPADDRESS to 9.9.9.9 in that file I tried: StringRegExpReplace("IPADDRESS=10.10.10.10", "^IPADDRESS=.*$" "IPADDRESS=9.9.9.9") but I do not know if there is afunction that would find the value in the file and replace it with what StringRegExpReplace returns.

mikell Posted May 5, 2014 Share Posted May 5, 2014 It's not necessary to choose the hard way $txt = FileRead("net.txt") $txt = StringReplace($txt, "IPADDRESS=10.10.10.10", "IPADDRESS=9.9.9.9") FileWrite("net2.txt", $txt) ShellExecute("net2.txt") Link to comment Share on other sites More sharing options...
jguinch Posted May 5, 2014 Share Posted May 5, 2014 Mikell, I think IPADDRESS=10.10.10.10 was just an example...

mikell Posted May 5, 2014 Share Posted May 5, 2014 (edited) Oh, OK... Maybe like this then ? $txt = FileRead("net.txt") $ref = "IPADDRESS" $newvalue = "9.9.9.9" $txt = StringRegExpReplace($txt, "(?<=" & $ref & "=)\S+", $newvalue) FileWrite("net2.txt", $txt) ShellExecute("net2.txt") Edit Difficult to say more without additional infos...

jguinch Posted May 5, 2014 Share Posted May 5, 2014 ... or like this : $sContent = FileRead("file.txt") $pattern = "(?m)^IPADDRESS=(\d+\.){3}\d+" $sNewContent = StringRegExpReplace($sContent, $pattern, "IPADRESS=9.9.9.9") FileWrite("file2.txt", $sNewcontent) or more complex, to check the IP address format, but only be for the luxury $pattern = "(?xm) ^IPADDRESS=(?<!\d|\d\.) ( (?:(?: (?:(?:25[0-5] | 2[0-4]\d | 1\d{2} | [1-9]\d | \d )\.){3} (?:25[0-5] | 2[0-4]\d | 1\d{2} | [1-9]\d | \d ) ) " & _ " | " & _ "(?: (?:(?:25[0-5] | 2[0-4]\d | [0-1]\d{2} | (00)\d )\.){3} (?:25[0-5] | 2[0-4]\d | [0-1]\d{2} | (?:00)\d) )) ) (?!\d|\.\d)" Spoiler Network configuration UDF, _DirGetSizeByExtension, _UninstallList Firefox ConfigurationArray multi-dimensions, Printer Management UDF Link to comment Share on other sites More sharing options...
valfar999 Posted May 5, 2014 Author Share Posted May 5, 2014 I will test those and see. The file will contain other variables and different values (hostnames, names, etc), so that it is why I have to use regular expressions. In sed I would do something like sed -i "s|^IPADDRESS=.*$|19.9.9.9|g" file.txt but I had no idea how to do this in Autoit. I will post back once I try your examples.

valfar999 Posted May 5, 2014 Author Share Posted May 5, 2014 I tried $txt = FileRead("net.txt") $ref = "IPADDRESS" $newvalue = "9.9.9.9" $txt = StringRegExpReplace($txt, "(?<=" & $ref & "=)\S+", $newvalue) FileWrite("net2.txt", $txt) but every time I run the script it duplicates the whole file content. I tried adding FileOpen/FileClose with different flags (Specially 2), but when I do that it does not work. How can I stop the script from duplicating the whole content of the file whenever I run it?

valfar999 Posted May 5, 2014 Author Share Posted May 5, 2014 I got it working now, but the problem now is that when I add a value between the = sign and the value and expressions does not work. Ex: Variable=Value (Works) Ex: Variable = Value (Does not work) BTW, I was reading and writing to the same file, so I just had to close the file, reopen it with fileOpen using the second flag that that did it.

BrewManNH Posted May 5, 2014 Share Posted May 5, 2014 What exactly does the contents of this file contain? Is it an INI file or something similar?

valfar999 Posted May 5, 2014 Author Share Posted May 5, 2014 Nah, if it was I woulda used InitRead. It has different variables and values for a config file Im working on Ex: Variable1=xyz Variable2=qwe Variable3=cwrvb3rb I have to change the values according to what a user chooses in my GUI, so that is why I have to be able to find the Vriable and change its value depending on that the user chooses. I cannot convert this to ini format because the application I will be using this with does not support that format. Link to comment Share on other sites More sharing options...
jguinch Posted May 5, 2014 Share Posted May 5, 2014 Try with something like this : $newvalue = "9.9.9.9" $sContent = FileRead("file.txt") $hFile = FileOpen("file.txt", 2) $pattern = "(?im)^IPADDRESS(\h*)=(\h*).*$" $sNewContent = StringRegExpReplace($sContent, $pattern, "IPADRESS${1}=${2}" & $newvalue) ConsoleWrite($sNewContent) FileWrite($hFile, $sNewContent) FileClose($hFile) Spoiler Network configuration UDF, _DirGetSizeByExtension, _UninstallList Firefox ConfigurationArray multi-dimensions, Printer Management UDF Link to comment Share on other sites More sharing options...
