A Resource Mover in Modula-2

Moving Resources in Modula-2

The Macintosh's built-in ability to deal with resources can both complicate and simplify life for the Mac programmer. Resources allow many items that would normally be hardcoded into a program to be separated from the code and made independent of program compilation. Typical resources include windows, dialogs, controls, and icons. Many utility-type programs need to move resources from one file to another. This article will present the steps necessary to move resources and provide the sources to a library module and a demonstration program.

Clearing a resource file

The first routine I needed while designing a module to copy resources was a procedure to clear a resource file of all resources. In dealing with the Mac, it seems like there's always a ToolBox routine at hand to do exactly what you want. In this case, I could find no routine to clear a resource file. My first cut at writing a resource clearing routine worked by finding all the resources that belonged to the desired resource file and then individually removing the resources by calling RmveResource. For some unexplainable reason, this method did not work. Sometimes it would take more than one pass over the file to delete all the resources. Out of frustration, I resorted to a more brute-force, direct technique. This method involved opening the resource file using the File Manager and directly manipulating its contents to mimick that of an empty, newly created resource file. Figure one shows the contents of a resource file after it has been "cleared" by my ClearRsrcFile routine (see the commented routine in the MoveResources.MOD file).

PROCEDURE ClearRsrcFile
                  (file : ARRAY OF CHAR) : INTEGER;

There are two ways to open a resource file. Normally, the Resource Manager's OpenResFile routine is called. This routine looks only on the default volume for the specified file (unless one passes the volume name as part of the filename; a no-no according to Apple and might not work with the HFS). Therefore, always do a SetVol to the volume containing the resource file before calling OpenResFile. It is interesting to note that the Resource Manager in the new ROMs includes a call called OpenRFPerm that allows you to specify the volume reference number along with the resource file (and permission too!). The other way to open a resource file is with the File Manager's FSOpenRF call. FSOpenRF treats the resource file as a traditional data file and OpenResFile treats the file as a collection of resources. Since the ClearRsrcFile routine needs to go in and fool with the resource file directly, I used the FSOpenRF call to open the file.

Figure 1. A cleared resource file.

Copying a resource file

The next step in designing a resource copying module was to design a resource copying routine. I wanted the routine to be very simple from a user's point of view. The routine takes two resource file reference numbers, one the source and the other the destination, and simply copies all resources from one file to the other. Other parameters of the routine specify whether information about each resource should be printed as the resource is copied and whether duplicate resources should be replaced or flagged as an error. Finally, a fairly involved error record is passed to the resource copying routine so that if an error occurs, the caller has a chance at doing some sort of sophisticated error recovery.

PROCEDURE MoveRsrcs 
 (src, dest : INTEGER;
 noisy : BOOLEAN;
 allowDuplicate: BOOLEAN;
 VAR error : RsrcErr);

The resource copying routine (called MoveRsrcs in the the MoveResources.MOD file), basically follows these steps:

1- Turn off resource loading by calling SetResLoad(FALSE). This tells the Resource Manager not to load the resource data associated with each resource into memory (of course, those resources marked as "preloadable" will have already been loaded by the OpenResFile call). After every Resource Manager call, the procedure CheckError is called to check for a Resource Manager error. If an error did indeed occur, resource loading is turned back on by calling SetResLoad(TRUE). Leaving a program without setting resource loading back on causes serious problems!

2- Find all the resources associated with the source resource file. We loop through all the resource types and the various resources of each type (by calling CountTypes and CountResources) and get a handle to each resource. Unfortunately, we must look at every resource from every open resource file just to find the resources that belong to a specific file. When you ask the Resource Manager for a resource, it checks all of the open resource files and there is no way to limit its search to one file (although the order of the search can be changed). The new ROMs, however, now implement a number of new Resource Manager calls that only search a single resource file (routines such as: Count1Resources, Get1IndType, etc). Of course, by using any of the new ROM calls, the program wouldn't work on a Mac with the old ROMs. The HomeResFile routine tells us which resource file a resource belongs to. If the resource belongs to the source file we are interested in, then the handle to the resource is saved by our module in a linked list.

3- Loop through the selected resources. Each selected resource handle is removed from the linked list.

a- Load the resource into memory by specifically calling LoadResource. LoadResource will load the resource even though SetResLoad is FALSE.

b- Call GetResInfo to find out the resource's name, type, and id.

c- "Detach" the resource with DetachResource. In other words, tell the Resource manager to "forget" about it.

d- Check to see if the destination resource file already contains the same resource and handle a possible collision.

e- Add the resource to the destination resource file.

4- Turn resource loading back on (SetResLoad(TRUE)) and return.

Step 2 mentioned that the resource manager searches all the open resource files when performing various operations. In the case of MacModula-2, these files could include: the System file, the Modula-2 interpreter, the .LOD file that uses the resource copier module, the source resource file (the one we're copying), and the destination resource file (the one we're copying to). Actually, the Resource Manager keeps a linked list of all the open files and it sequentially searches the files in the list. By calling UseResFile, one can change the order of this linked list. In fact, UseResFile is called in a number of places where it is desireable that either the source or destination file be searched first.

Figure 2. MoveResource program.

An applications program

The sample application program provides a front-end to the MoveResource module (see figure 2). The program (called MoveResources.MOD) displays the SFGetFile dialog box and prompts the user to select a source resource file. If the file has a resource fork, the user is asked to select a destination resource file and decide whether the destination resources should be cleared. Finally, the resources are copied from the source to the destination file.

Since the Mac is so tied to resources, it's important that we understand how to manipulate these resources. I hope that you will be able to make use of the code or concepts discussed in this article in your own projects.
