((s1 What is it about?

Traditionally, Macintosh files have always been constituted of two forks:
the data fork and the resource fork. This latter contains all kinds of
resources, which are data in a predefined format used by the application
while it is running (icons, menus, strings etc.) or by the system itself.
The main draw back of this model is that, when a Macintosh file is copied
to another system, it generally looses its resource fork and most of the
time it becomes unusable. Since system 9, for the sake of portability of
software to other operating systems, Apple has introduced the notion of
resources stored in the data fork of a file rather than in the resource
fork. Bundled applications, for instance, can thus store their resources in
separate files contained in the bundle.

((b ToggleFork b)) is a simple drag and drop tool which lets you transfer the
resources from a fork to the other. If you have an editor (like
ResEdit) which is ((i not i)) able to edit resources contained in the datafork of a
file, you can use ToggleFork to get a file having the same resources in its
resource fork and view or edit them. The converse is true: you can prepare
your resources with a traditional editor in the resource fork of a file and
get a datafork resource file using ToggleFork.

((s1 How does it work?

Just drag a file over the icon of ((b ToggleFork b)):
((lu
((li if it is a traditional file with both a data fork and a resource fork,
its resource fork will be rewritten in the data fork of a separate file
called by default ((i Out.datafork i)). The original file is unmodified.

((li if it is a file containing resources in its datafork, all its
resources will be copied to the resource fork of a separate file called by
default ((i Out.rsrcfork i)). The original file is unmodified.

((li if the file has no resource, nothing happens.
lu))
((b ToggleFork b)) is a background only application which immediately 
quits after it has done its job. You should normally not even see it in 
the Dock.

((s1 Download

((b ToggleFork b)) can be found on 
((lk http://perso.orange.fr/bdesgraupes/tools.html )) my web page lk)).

Click to 
((lk http://perso.orange.fr/bdesgraupes/Downloads/ToggleFork.hqx )) download ToggleFork lk))

You need Stuffit Expander to unpack it.

((s1 Scriptability

((b ToggleFork b)) is scriptable so you can drive it with ((b AppleScript b)). The
terminolgy contains a single term: ToggleFork with an optional parameter
((i to i)) which lets you specify the name of the output file instead of the
default names mentioned above.
((|
    tell application "ToggleFork"
    ToggleFork "HD:folder:subfolder:somefile" as alias
    end tell
|))
or 
((|
    tell application "ToggleFork"
    ToggleFork "HD:folder:subfolder:somefile"  as alias to "the_new_name"
    end tell
|))

Here is ToggleFork's dictionary as reported by AppleScript Editor:

((|
    ToggleFork: Exchange resource forks (data fork resources 
    		  become resource fork resources and vice versa)
    	ToggleFork  alias  -- the input file
    		[to  string]  -- name of the output file

    Quit: Quit the application
    	Quit
|))

((s1 AppleEvents

If you want to use AppleEvents directly, the ((i ToggleFork i)) term is
attached to the ((i aevt/odoc i)) event. The optional parameter has code
'name'. For instance, if you use the text editor 
((lk http://alphatcl.sourceforge.net/wiki )) ((i Alpha i)) lk)) (which has a
((lk http://wiki.tcl.tk/ )) Tcl lk)) interpreter), you would write, in a
Tcl script or in Alpha's Tcl shell, something like:

((|
    set filename "HD:folder:subfolder:somefile"
    AEBuild -r 'TgFk' aevt odoc ---- [tclAE::build::alis $filename]
|))
or
((|
    AEBuild -r 'TgFk' aevt odoc ---- [tclAE::build::alis $filename] \
    	name [tclAE::build::TEXT "some_new_name"]
|))

((s1 Why ToggleFork?

OK, I know, one can open a Terminal window in OSX and type commands like 
this:
((|
    touch SomeApp-rsrcfork.rsrc
    cp SomeApp.rsrc SomeApp-rsrcfork.rsrc/rsrc
    rm SomeApp.rsrc
    mv SomeApp-rsrcfork.rsrc SomeApp.rsrc
|))

So why should you use ToggleFork? Well, matter of taste: instead of typing
command line instructions, all you have to do is drag and drop your file on
the icon of ToggleFork. And ToggleFork is scriptable, which is great for
script lovers.
