Read determined value of .INF file

[LuisMartins]

Hi there,

So I got this .INF file, example:

// Some text
// Another text
Version=1.0

And I'm trying to get only the value 1.0 in my script.

I tried:

IniRead(@ScriptDir & "\myapp\version.inf", "", "version", "NULL")

I guess it didn't work because it doesn't have sections like an .INI .

I'm also trying FileSetPos but no luck with it.

Any help?

Thanks in advance!

I believe you need a section in your .ini file. For example:

[Description]
Version=1.0

Edit: I see you mentioned that already. You'll have to parse it somehow.

The thing is, the .INF file may be updated and I'd rather not have to edit it everytime to add a Section.

And IniRead would be perfect, because it has this thing that when the value isn't found is assumes the defined default value, in my case "NULL".

The closer I can get is with FileReadLine, which as the name says, gives me the line I want, but I still need just the value after Version=

Unfortunately your INF file isn't in the correct format to be used with the INI* functions. In fact, it doesn't appear to be in the correct format for an INF file either, seeing as how the INF and INI formats are the same. You're going to have to do some parsing of the file, perhaps with FileRead and StringRegExp to determine if the version line is in there or not.

LuisMartins,

Here is a technique that you can build on (this is one of many ways to do this):

#include <array.au3>

; create a test file to simulate your .INF file

local $str = '// Some text' & @crlf & '// Another text' & @crlf & 'Version=1.0' & @crlf & 'more data of any kind'
local $hfl = fileopen(@scriptdir & 'tmp010.inf',2)
filewrite($hfl,$str)
fileclose($hfl)
$hfl = 0

; read inf file to string

local $str = fileread(@scriptdir & 'tmp010.inf')

; search for your string

local $srch = stringregexp($str,'(?i)version.*',3)
if @error = 1 then
    ConsoleWrite('String not found' & @LF)
    Exit
endif

; display results

_arraydisplay($srch)

Thank you, both answers were useful.

But still, my bad, forgot to mention, there's still one problem.

I have another string before "Version=1.0", which is "firstversion=0.1", example:

// Some text
// Another text
firstversion=0.1
Version=1.0

So, assuming that its value may also get updated, I don't think I can really rely on StringRegExp, I guess.

Maybe you should post a sanitized version of the complete file, this way we know what we're dealing with, and not having you move the goal posts whenever something is posted.

[LuisMartins]

// NetworkVersion is the version in the wire protcol between client<->server,
// its not used for matchmaking, PatchVersion is used for that to ensure
// we don't get cross connecting to different releases.  Only bump this if
// you know an incompatible change has happened to the network protocol in
// game and old demos will not work.
NetworkVersion=2.0.4.2
PatchVersion=2.1.1.8
ProductName=left4dead2
appID=550

My goal is to get the number 2.1.1.8 and only that number. Considering the versions may change with updates I want my application to always stay up to date whenever they change without having to do it manually myself.

This is why you should have posted what you're actually looking at instead of being so obtuse in the first posts. This is only slightly like what you were asking for in the first place. The word version appears in that file several times. If we had known that before we could have come up with a much better answer for you earlier.

local $str = fileread(@scriptdir & 'test.ini'); change this to your file name 

; search for your string

local $srch = stringregexp($str,'(?i)PatchVersion=(.*)',3)
if @error = 1 then
    ConsoleWrite('String not found' & @LF)
    Exit
endif
_ArrayDisplay($srch)

[LuisMartins]

Ok thanks, that actually shows only the value.

But I'm not able to compare the returned value of $srch with another value, like:

If $srch = "2.1.1.7" Then
     MsgBox("", "Error", "Your version is not up-to-date.")
EndIf

Any advice?

It returns an array, you'd need to write it like this.

If $srch[0] = "2.1.1.7" Then
     MsgBox("", "Error", "Your version is not up-to-date.")
EndIf

[LuisMartins]

Ok thank you again, it's working great now.

Just out of curiosity is the version number always a single digit e.g. d.d.d.d?

[jdelaney]

may want to also add a boundry:

#include <Array.au3>
$str = "NetworkVersion=2.0.4.2" & @CRLF & _
"PatchVersion=2.1.1.8" & @CRLF & _
"LastPatchVersion=2.1.1.7" & @CRLF & _
"ProductName=left4dead2" & @CRLF & _
"appID=550"

local $srch = stringregexp($str,'(?i)bPatchVersion=(.*)',3)
_ArrayDisplay($srch) ; returns one result
local $srch = stringregexp($str,'(?i)PatchVersion=(.*)',3)
_ArrayDisplay($srch) ; returns two results

[BrewManNH]

may want to also add a boundry:

Can't hurt, although not necessary if they don't use "PatchVersion=" anywhere else in the file. But better to play it safe.

Yes, it is.

may want to also add a boundry:

#include $str = "NetworkVersion=2.0.4.2" & @CRLF & _ "PatchVersion=2.1.1.8" & @CRLF & _ "LastPatchVersion=2.1.1.7" & @CRLF & _ "ProductName=left4dead2" & @CRLF & _ "appID=550" local $srch = stringregexp($str,'(?i)\bPatchVersion=(.*)',3) _ArrayDisplay($srch) ; returns one result local $srch = stringregexp($str,'(?i)PatchVersion=(.*)',3) _ArrayDisplay($srch) ; returns two results

Well like I said, those versions will much probably get updated and therefere I can't rely setting them manually...

[jdelaney]

My example was just to demonstrate finding the actual data you need, when tokens exist with similar names.

[LuisMartins]

Thanks for the heads up.
