Indeed. That is an option (though it appears you have an extra "}" in the function there). I like the previous approach, however, as it keeps the line in script as brief as possible... but it really does not matter. Either way, I think it is about as good as it will get for AviSynth 2.5.8 compatibility.

How about others here: do you have a preference as to whether the attempt at 2.6's native ScriptName() is tried in the .avs or the function?

I don't think it matters much either way, but FWIW I think jmartinr's solution is slightly 'cleaner', as
- it uses one try/catch instead of two;
- it does not depend on '_' being previously undefined (and so can be used more than once in a script);
- it makes the function more self-contained - its job is then simply to extract the file name from a specified error message, so it could in principle be used in other contexts.

Alright then. Those are reasons enough for me! Here it is again, almost like in jmartinr's post but cleaned up a little more (and using '_' in the function for brevity and consistency)

Code:

# in .avs script
Try {_ = ScriptName()} Catch(_) {_=_ScriptName(_)}
AVSfilename = _

# in .avsi file
function _ScriptName(string _) {
        _ = MidStr(_, FindStr(_, "(") + 1)
        LeftStr(_, StrLen(_) - FindStr(RevStr(_), ","))
}

As good as it gets?

if you put theses function in the top of your avs file you will get the same effect of ScriptName(), and ScriptDir() in version 2.58

Code:

Function ScriptName(){try{_}catch(err_msg){return Chr(34)+RevStr(MidStr(RevStr(MidStr(err_msg,Findstr(err_msg,"(")+1)),FindStr(RevStr(MidStr(err_msg,Findstr(err_msg,"("))),",")+1))+Chr(34)}}
Function ScriptFile(){try{_}catch(err_msg){return Chr(34)+MidStr(RevStr(MidStr(RevStr(MidStr(err_msg,Findstr(err_msg,"(")+1)),FindStr(RevStr(MidStr(err_msg,Findstr(err_msg,"("))),",")+1)),StrLen(RevStr(MidStr(RevStr(MidStr(err_msg,Findstr(err_msg,"(")+1)),FindStr(RevStr(MidStr(err_msg,Findstr(err_msg,"("))),",")+1)))-FindStr(MidStr(RevStr(MidStr(err_msg,Findstr(err_msg,"(")+1)),FindStr(RevStr(MidStr(err_msg,Findstr(err_msg,"("))),",")+1),"\")+2)+Chr(34)}}
Function ScriptDir(){try{_}catch(err_msg){return Chr(34)+RevStr(MidStr(MidStr(RevStr(MidStr(err_msg,Findstr(err_msg,"(")+1)),FindStr(RevStr(MidStr(err_msg,Findstr(err_msg,"("))),",")+1),FindStr(MidStr(RevStr(MidStr(err_msg,Findstr(err_msg,"(")+1)),FindStr(RevStr(MidStr(err_msg,Findstr(err_msg,"("))),",")+1),"\")))+Chr(34)}}

StainlessS · 6th September 2012, 22:04

You need to remove the CHR(34)'s
EDIT: They are already strings, it's good to enclose in quotes before you give a filename to eg a DOS
command, but not before eg concatenating file name node to a directory, you would need to remove the
quotes, concatenate and then put them back again, not good.
EDIT: Name changes might be good too, eg ScriptDir25 or whatever.

EDIT: this might be handy,

Code:

ver = VersionNumber() # Float, Implemented v2.07

StainlessS · 6th September 2012, 23:37

Thought it might be an idea to point out somewhere in these simulated ScriptName etc threads that
SMPlayer (built on MPlayer)) returns returns paths with a '/' separator instead of DOS '\' causing
the simulated functions to fail, 2.6 functions cope just fine. EDIT: Perhaps it dont, see next post.

StainlessS · 7th September 2012, 00:13

Correction on previous post, v2.6 may not cope just fine when called via eg smplayer with Unix style '/' path separators.

Code:

# 2.6, Windows Media Player 2
Scriptname= C:\z\26.avs	
ScriptDir= C:\z\	
Scriptfile= 26.avs	

simulated scriptdir= C:\z\	


# 2.6 smplayer	
Scriptname= C:/z/26.avs	
ScriptDir= C:\z\	
Scriptfile= 26.avs	

simulated scriptdir= C:/z/26.avs, line 10)

2.6 ScriptDir DOS style '\' whereas, ScriptName uses Unix '/', presume this one or other is an error.

@all,
after mf/stickboy's help, I made myself an .avs file template in 2009. I can create this template by using shortcuts in various file commanders, or dragging a video file onto a vbs icon, or using windows' "new" context menu command ...

In my case, the template contains the try ... function, but I gave that function the name Me().

Thus:

Code:

function Me() {
    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), ",") - 4)
        return filename
}}

Below, the template says

Code:

Show(Me+"")  #object oriented people say: Me.Show

and that's all.

Show() is another function that I put together over the years. It checks for existence various extensions to Me, so it can work the same, whether Me is the basename of an .avi, a .mp4, a .mpg, a .flv ... and it uses totally different source filters, depending on the found extension, of course. It automatically Audiodub()s two sources for demuxed media etc.
Show() also automatically splices up to about 20 media files together. I.e. the script 01+02.avs will find the sources 01.avi and 02.avi, and present them as one.

And I made Show() also parse the string Me not only for the file name, but in fact that string can contain AviSynth commands. I decided to separate the part of the Me string that comes in front of the first pair of semicolons, and to use the rest of the script name as space that is executed by Eval():

Code:

    pos = findstr(name, ";;")
    args = pos > 0 ? MidStr(name, pos+2) : ""
    name = pos > 0 ? LeftStr(name, pos-1) : name
...
    GEval( Replace( Replace( args, ";;", chr(13) ), "''", chr(34) ) )

That means I can write an AVS script into the file name of the script itself, where I type a pair of ;; for a newline and a pair of single quotes '' for a quote ".

The reason for adding an empty string +"" to Me for Show() is, of course, that I can also add script commands to a file that is open in the editor, instead of changing the file name in this case.

Why am I writing all this in the forum?

First, because it is one possible answer on how to modify the script behaviour easily, without opening an editor - by a different variable definition in the name of two scripts (e.g: two template files myfile;;preview=true.avs and myfile;;preview=false.avs provide the variable preview inside your script, so it can react on it. Show() reacts on a set of variables I need often.

Second, to point out the importance of having the base name, in contrast to the complete file name, of the .avs script. Of course, that can easily be derived from ScriptName. But that again needs one user function to be written (many of us will have to do so, or one does it and many copy it), so it would be less effort in total - and reasonable - if AviSynth provided ScriptBaseName right away.

Both above funcs have standard Avisynth versions (commented out) and RT_StrAddStr() version which fixes a bug in 2.58 & 2.6a3.

EDIT:
Have edited to implement as a new separate function, StrReplaceDeep (alternative name suggestions ?).

And also, from whence did you obtain Aug 2012 executable.

(ScriptName is builtin to 2.6) EDIT: Although it will (I think) be using script version instead, if supplied.

martin53 · 3rd December 2012, 18:54

Yep, sorry. I really forgot to be more specific.

Version.Subtitle(foo) says I don't know what "foo" means as expected.
Version.Subtitle(ScriptName) says Script error: Invalid Arguments to function "Subtitle"
Version.Subtitle(ScriptName()) says the same, also Version.Subtitle(ScriptDir), Version.Subtitle(Scriptfile) with and without additional function brackets.

Version.Subtitle("<"+string(Scriptname)+">") produces the version clip with <> subtitle.

assert(false,IsString(Scriptname)?"true":"false") returns false, likewise IsBool, IsClip, IsFloat, IsInt and Defined. While assert(false,IsString(foo)?"true":"false") returns I don't know...

ScriptName seems to be existent but of no type somehow.

I cannot remember where I downloaded the package from. Its file name is avisynth_2.60MTalpha_SEt_120828. The dll properties reveal version 2.6.0.3, 1.65MB from 08/28/2012 16:45

jmartinr · 4th December 2012, 10:59

Here it works.

Code:

Version.Subtitle(ScriptName)

Using Avisynth 2.60, build may 16 2012. If it's important to you, you might want to change versions.

Don't remember where I got this from, but it is an MT-version. It's still in my dowload-archive as a 7z-file. If you want you can download it at: http://roelofs-coaching.nl/downloads/avisynth.7z

Judging from the date, that is the previous version of SEt's 2.60 MT build, while martin53 appears to be using the latest one.

Looks like a bug has been introduced in the latest version - I don't know if SEt reads all the threads here, so I suggest you report it on the 2.60 MT thread.

vdcrim · 4th December 2012, 16:25

So the ScriptName function you're using is the included in AviSynth 2.6 or one of the script functions posted in this thread? If it's the former your problem must be that the program you're using to load the script doesn't support the v2.6 interface.

There's two ways to load an AviSynth script, using the VFW interface and loading AviSynth directly as a library and then calling env->Invoke + Eval. The ScriptName, ScriptDir and ScriptFile functions just return the string saved in a global variable of the same name that is set by AviSynth when using the VFW approach. On the second case the variables are still declared by AviSynth when creating the environment but as the script file is not opened by AviSynth itself they are left uninitialized. This is called in the AviSynth language a variable of type void. Void variables can't be created by scripting, I figure that that's why there isn't a IsVoid function.

So the caller application is responsible for setting those variables before creating the clip. I don't know how many programs currently do this. AvsPmod only started doing it in the recent 2.4.0 version.

Edit:there seems to be a mismatch between the AviSynth source code files and the wiki, as the later refers to not declared variables also as void.

martin53 · 4th December 2012, 18:06

vdcrim,
thanks for the helpful info.

I was using the included, not a script function, and I was using AvsPmod 2.3.0

The reason I appreciate the builtin function is that you cannot use script functions from included .avsi files - they return the name of that script instead of the calling one. So when you provide a filter script to others that needs to write files and you want to prevent collisions if the user opens more than one clip at a time... you need something unique, and the calling script name is good for that.

I verified that indeed opening the same script in VDub shows the string correctly.
However, between VDub (1.10.1 portable) and AvsPmod (2.4.0), there is an annoying difference:

in VDub, ScriptName shows the filename with path, while in AvsPmod, it shows only the filename without path.
In VDub, ScriptFile shows only the filename without path, while in AvsPmod, it shows the complete filename with path.

Now which one is intended and which is wrong? The terms 'name' and 'file' are not very unmistakable.
Edit: according to the prior usage of the function names in this thread, AvsPmod is wrong. Solution is in pyavs.py lines 126/127, but I cannot build AvsPmod.

I kindly ask the AviSynth developer team to please clarify the intention of the variable names and initiate the solution. Should I help to forward the issue somehow?
Edit: posted the issue in the AvsPmod thread

If the script is in a file, the usual way to load it using Avisynth as a library is to call env->Invoke("Import") (not Eval).
It's the Import() function (not the VfW interface per se) that sets the global variables, so ScriptName() should still work with this approach. AvsP[Mod] is different as it already has the text in a buffer, so uses Eval instead of Import.

The Defined() function is the equivalent of IsVoid. A void variable can be created by passing a default parameter, or (in v2.60) using the Undefined() function.

As implemented by Avisynth, ScriptName is the actual string passed in to Import(), and may or may not be the full path, depending on the caller.

ScriptDir and ScriptFile are the full path of the containing folder, and the basic filename part, respectively.

First, because it is one possible answer on how to modify the script behaviour easily, without opening an editor - by a different variable definition in the name of two scripts (e.g: two template files myfile;;preview=true.avs and myfile;;preview=false.avs provide the variable preview inside your script, so it can react on it. Show() reacts on a set of variables I need often. Second, to point out the importance of having the base name, in contrast to the complete file name, of the .avs script. Of course, that can easily be derived from ScriptName. But that again needs one user function to be written (many of us will have to do so, or one does it and many copy it), so it would be less effort in total - and reasonable - if AviSynth provided ScriptBaseName right away.

If it's important to you, you might want to change versions. Don't remember where I got this from, but it is an MT-version. It's still in my dowload-archive as a 7z-file. If you want you can download it at: http://roelofs-coaching.nl/downloads/avisynth.7z __________________ Roelofs Coaching

Version.Subtitle(ScriptName) says Script error: Invalid Arguments to function "Subtitle" Version.Subtitle(ScriptName()) says the same, also Version.Subtitle(ScriptDir), Version.Subtitle(Scriptfile) with and without additional function brackets. Version.Subtitle("<"+string(Scriptname)+">") produces the version clip with <> subtitle. assert(false,IsString(Scriptname)?"true":"false") returns false, likewise IsBool, IsClip, IsFloat, IsInt and Defined. While assert(false,IsString(foo)?"true":"false") returns I don't know... ScriptName seems to be existent but of no type somehow. I cannot remember where I downloaded the package from. Its file name is avisynth_2.60MTalpha_SEt_120828. The dll properties reveal version 2.6.0.3, 1.65MB from 08/28/2012 16:45

If it's the former your problem must be that the program you're using to load the script doesn't support the v2.6 interface. There's two ways to load an AviSynth script, using the VFW interface and loading AviSynth directly as a library and then calling env->Invoke + Eval. The ScriptName, ScriptDir and ScriptFile functions just return the string saved in a global variable of the same name that is set by AviSynth when using the VFW approach. On the second case the variables are still declared by AviSynth when creating the environment but as the script file is not opened by AviSynth itself they are left uninitialized. This is called in the AviSynth language a variable of type void. Void variables can't be created by scripting, I figure that that's why there isn't a IsVoid function. So the caller application is responsible for setting those variables before creating the clip. I don't know how many programs currently do this. AvsPmod only started doing it in the recent 2.4.0 version. Edit:there seems to be a mismatch between the AviSynth source code files and the wiki, as the later refers to not declared variables also as void. Last edited by vdcrim; 4th December 2012 at 16:53.

martin53 Registered User Join Date: Mar 2007 Posts: 407	vdcrim, thanks for the helpful info. I was using the included, not a script function, and I was using AvsPmod 2.3.0 The reason I appreciate the builtin function is that you cannot use script functions from included .avsi files - they return the name of that script instead of the calling one. So when you provide a filter script to others that needs to write files and you want to prevent collisions if the user opens more than one clip at a time... you need something unique, and the calling script name is good for that. I verified that indeed opening the same script in VDub shows the string correctly. However, between VDub (1.10.1 portable) and AvsPmod (2.4.0), there is an annoying difference: in VDub, ScriptName shows the filename with path, while in AvsPmod, it shows only the filename without path. In VDub, ScriptFile shows only the filename without path, while in AvsPmod, it shows the complete filename with path. Now which one is intended and which is wrong? The terms 'name' and 'file' are not very unmistakable. Edit: according to the prior usage of the function names in this thread, AvsPmod is wrong. Solution is in pyavs.py lines 126/127, but I cannot build AvsPmod. I kindly ask the AviSynth developer team to please clarify the intention of the variable names and initiate the solution. Should I help to forward the issue somehow? Edit: posted the issue in the AvsPmod thread Last edited by martin53; 4th December 2012 at 18:34.
