Get the current script filename

[jcsston]

Is it possible to get the filename of the current AVS script file inside a filter?
I want to make a Audio Normalizing filter that caches the the peak levels to an external file so that it only has to scan it once.

Is seems that this is not exposed in the API.

[mf]

function GetScriptName() {
Try { NonExistantfiltername() }
Catch(err_msg) {
err_msg2 = MidStr(err_msg, 67)
filename = LeftStr(err_msg2, (FindStr(err_msg2, ", line")-1))
return filename
} }

Whaouh, mf saves the day !

I went ahead and made the filter but it takes the peak value file as an argument.
Normalize2

Now with mf's function I can get similar results to what I wanted.

function GetScriptName() {
Try { NonExistantfiltername() }
Catch(err_msg) {
err_msg2 = MidStr(err_msg, 67)
filename = LeftStr(err_msg2, (FindStr(err_msg2, ", line")-1))
return filename
} }
...
Normalize2(GetScriptName()+".norm")

Glad I could be of help .

} }

That's sick.

But it won't work for the contrived case where the filename has ", line" in it. Here's a modified version (and that also isn't dependent on NonExistentFilterName):

function GetScriptName()
{
    Try
    {
        assert(false)
    }
    Catch(err_msg)
    {
        err_msg = MidStr(err_msg, FindStr(err_msg, "(") + 1)
        filename = LeftStr(err_msg, StrLen(err_msg) - FindStr(RevStr(err_msg), ","))
        return filename
    }
}

Well, you know I like to write dirty code .

you are VERY creative !

Yo, did somebody call?

Whoops! I meant jcsston. Both matroska monkeys .

I'm a bit confused as usual

I understand the GetScriptName function (hats off to mf) but I don't understand what Normalise2 is doing with it and what is meant by caching so it only has to scan the file once

I'm sure its simple but the usage has got me stumped

I guess it uses the script filename to create another one and save into it the audio peak value.
So if that second file exists, no need to scan anymore.

Here's my slighlty more efficient version, only one string, and safer as script name must not contain ", line " instead of ", line" (extra char), and it doesn't depend on a fixed length of error code.

function GetScriptName() {
  try { willGiveNonExistantError() }
  catch(err_msg) {
    pos1= findStr(err_msg, "(")
  }
  return midStr( err_msg, pos1+1, findStr(err_msg, ", line ")-pos1-1 )
}

@isidroco, that function maybe was useful in 2003 but after AviSynth 2.6 (2015) there are already a internal function ScriptName()
