Re: Lisp file/application associations

Thanks Raffael, Fredrik, james, and Laughing.

I guess what I might be meaning is rather than assigning application 
associations to files explicitly (by hand), is there any way to patch 
MCL so it creates the appropriate association automatically.

I would expect an application to write files (at least initially) 
such that they would open in their own app by default. Some time back 
I used the Change All option in the Get Info dialog to link lisp 
files to CLZ. Now MCL files are saved as CLZ files.

Where in the file itself is the application association bound, and 
would it be viable to modify MCL to do this automatically.

I don't see a lisp entry in 
~/Library/Preferences/com.apple.LaunchServices.plist
but do see attribute: <key>LSHandlerIgnoreCreator</key> and wonder if 
that is relevant.
The converse of which might help in dissociating MCL (creator code 
CCL2) and CLZ (no creator code)?
Or their Type codes (CLZ null null null, MCL TEXT).
But if Creator and Type codes are redundant now, just how is 
association per file stored?
It can't be via the .DS_Store file per folder as we can have both MCL 
and CLZ files in the same folder.
When a file association is changed, its Modified date is changed, so 
presumably some data is changed in the file.  Isn't this what I want 
to automatically assign at file birth?
As it is, to hand modify files changes mod dates which messes up my 
code change tracking system.
No doubt I'm missing something really obvious.
