Source Command - Relative Path To Where?

[mnhan32]

Hey guys,
I had a global proc as my main entry. And, in that proc, it source other three proc in a subfolder reltive to itself.
So, say mainEntry.mel is located at D:\myScript and the other three proc, A.mel, B.mel, C.mel, are in D:\myScript\proc\

In mainEntry.mel, I have the following script.

CODE
global proc mainEntry(){
source "./proc/A.mel";
source "./proc/B.mel";
source "./proc/C.mel";
}

And, this all works fine if I source mainEntry.mel manually.
However, If I then copy the mainEntry.mel and the subfolder to any folder in my MAYA_SCRIPT_PATH, so Maya will source it automatically at startup, I get an error while calling mainEntry proc. Although it recognized mainEntry, Maya can not locate my other proc in the subfolder for the source statement. Does that mean that if Maya source my mainEntry at startup, "./" is not relative to my mainEntry.mel? Is there any way to solve this? I mean, how can have my script sourced successfully manually and automatically?

open maya.env

add

CODE
MAYA_SCRIPT_PATH=D:\myScript;D:\myScript\proc;

then
CODE
global proc mainEntry(){
source "A.mel";
source "B.mel";
source "C.mel";
}

Yeah, I know that works.
However, if the users don't put the scripts in any folder in MAYA_SCRIPT_PATH, this won't work, caz, in this situatiuon, mainEntry.mel will need "./proc/A.mel".
Just wonder if there is a way to do make it works for both situations, so that the users can choose to source the scripts by themselves, or to put the scripts under any path of MAYA_SCRIPT_PATH, and let Maya sources it at startup.

This just hits me.
Maybe I should write a proc that checks if myScript folder existed in maya.env, if true, then use "proc/A.mel", if false, use "./proc/A.mel"; That should work.

use what whatIs on the main entry proc, extract its path and append the relation to that.

The realtion in maya is in relation to current working directory wichis the workspace.

Tks Joojaa,
It's a great idea. I made a proc that will return absolute path of an input proc name.

CODE
proc string validPath(string $inputProcName)
{
string $whereIsMainEntry = whatIs($inputProcName);
string $absolutePath  = substitute "Mel procedure found in: " $whereIsMainEntry "";
string  $validPath = dirname($absolutePath);

return $validPath;
}

So in my mainEntery proc, I can call this and get where the mel file is.

CODE
proc mainEntry()
{
string $myPath = validPath mainEntry;
string $subFolder = "proc";
string $melFile = "test.mel";
string $wholePath = $myPath+"/"+$subFolder+"/"+$melFile;

string $evalMe = ("source \""+ $wholePath  +"\"");
eval $evalMe;
}
