Library Manager Cures HFS Brain Damage

By Dave Rausch, Fullerton, CA

“File Not Found!”

How many times have you run a compiler or linker program only to have it come up and say “file not found” after which the program returns you to the Finder or worse, crashes the system. Then you have to find the mystery file the program wants, then figure out which folder the program expects to find it, and try to coerce the program into locating it. Programs that make you do this are HFS brain damaged. They can’t find their way out of a paper bag. Microsoft is notorious for products which either can’t find files (MS Basic) or require files to be in certain folders (MS Word), or die when a file cannot be found (MS Fortran). While Apple provided an elegant way for applications to allow the user to find a document, via the standard file dialog, no thought was given to those types of programs which must locate a library or reference file that is either not known to the user, or not directly related to a user created document, but which is vital for the program to function. Think Technologies with their Lightspeed C and Pascal was one of the first companies to market a truly HFS smart compiler. If LS Pascal can’t find a file it needs, it asks the user to find it! What could be simpler or more straight forward? Who needs path managers? Who needs Finder DA’s? Who needs path name scripts? In this article I show how you can use this technique to make your applications HFS smart, by putting up a standard file dialog if a library file cannot be found. Once the user finds the file, it’s location is remembered in a resource so the dialog does not have to be repeated unless the file is moved or renamed. Why should a program (like 4th Dimension) prevent you from moving or renaming your files? Even though HFS has been with us for over a year and a half, many developers are still working around it, not with it. It’s time to make our programs HFS friendly and this article will show you how to do it.

Library Manager Tracks Your Files

As Macintosh programs become smarter and heftier, the need increases to maintain libraries of information that are external to the application itself. Because I am currently developing an application that requires three separate kinds of open file lists, I spent some time putting together what I call a “Library Manager” to help keep things straight. The classic example of a file you would use the library manager to track and open is the “dictionary”, a library type that may include a whole list of generic, technical, and user-defined files that should be opened automatically without unnecessary user intervention and without the user having to place them in either (a) the same folder with the application or (b) the System Folder which is beginning to get cluttered...; (Acius, are you paying attention?)

Fig. 1 Let the user find it!

Our application is a demonstration of how an application can be designed to keep track of and locate files without crashing, quiting or forcing the user to place or name files in a certain way. The demo application makes calls to what I have named the Library Manager, a unit of LS Pascal routines which provide the support for creating HFS friendly programs. By adding this Library Manager unit to your own projects, your applications can be made as HFS friendly as the products from Think Technologies.

Installing Library Manager

The Library Manager keeps track of application files using an application defined resource of type LMIR, Library Manager Information Resource. A separate LMIR resource is created for each file for which the application needs to know the whereabouts. The LMIR is shown defined below:

LMIR = RECORD  {Library Manager Info Record}
 rsrcID : integer;
 volname :  str31;
 vRef : integer;
 hfsvolume :   boolean;
 DirID :  Longint;
 filename : str63;
 fRefNum :  integer;
 next, prev :  LmirHdl;
 FTyp : integer;
 RecsOnFile, CurRec : integer;
 changed :  boolean;
 Status : (Open, Closed, NotFound);

Once the Library Manager code is added to an existing project and the routine OpenLib is called, the Manager is self-initializing. When a call is made to OpenLib for a LMIR resource that does not exist, OpenLib creates the resource and adds it to the current resource file. A typical setup routine is shown below that makes this call to OpenLib:

 OpenLib(TopFile, ‘Application Default Library’); 
 {When program boots}
 OpenLinkedLib(TopFile, ‘User Default Library’); 
 {When program boots}

When OpenLib is called, if the appropriate LMIR resource does not exist or if the file the resource points to has been moved (or renamed, is unmounted, etc.) the user is prompted and allowed (not forced) to find or create a new library file. The message displayed to the user tells him the exact nature of the problem: The volume isn’t mounted, the file can’t be found, the file is already open for read/write, etc. All of the possible HFS file problems are clearly trapped and displayed here. No more “call Aldus, error number 1234” stuff.

For the developer, this means that once the library manager is added to his code and calls are made to OpenLib, he can

(1) Ignore prompts to find or create the library (until ready)

(2) Create a new library file someplace (and not be bothered again)

(3) Tell the program where he has moved the library file to

(4) Mount the volume that the library file is on, if that is the problem.

Note that moving the application won’t disturb the Library Manager’s ability to find a file, only tampering with the location or name of the library file itself.

Lotsa Lovely Linked Lists of Libraries

When calls are made to OpenLinkedLib additional library files are linked using a circular forward and backward chain. As many separate lists of files as desired can be created with OpenLib, and as many files can be added to any particular list with OpenLinkedLib as the application demands. Thus you can support a whole bunch of related files that must be opened at run time.

The linked lists allow you to search through all files of a given library type by using a loop along the lines of:

 next := top;
 IFoundIt := YourSearchRoutine(next);
 next : next^^.next;
 until IFoundIt or (next = top);

Another agreeable aspect of linked lists is that the library manager requires you to define only one (global?) variable per list: the handle to the top item of the list.

Removing Files from a List

Call RemoveLib to close an open library file and remove it from the list. Note that RemoveLib always returns a valid handle if there are still any open libraries in the list. This allows you to remove even the “top” item from a library list, because RemoveLib automatically replaces it with a “new” top. If you are removing the top item from the list, you should reference it specifically when you pass it to RemoveLib.

 { that is, whatever variable name you passed 
 to Open Lib originally }





if there’s a chance that next or next^^.next = Top.

A file that has been removed with RemoveLib can be reopened with OpenLinkedLib or OpenLib.

RemoveLib checks whether the changed field of the Library Manager Record is true. If so, it calls HandleChanges. HandleChanges does nothing! It is just included to give you the general idea.

Closing All Open Files in a List

At exit time, call CloseLibList for each library list that is open. It will close all open files in a list, by successive calls to RemoveLib, until the list is empty.

Access is by Resource Name, not Resource ID

As you will see when you examine OpenLib and GetLibResource, the library manager accesses files by a descriptive resource name rather than by resource ID.

The Library Manager was developed to work in conjunction with routines that will extend menus by allowing the user to create new menu items and associate those items with individual files. If you are allowing the user to extend libraries in this (or some similar) way, you should call GetLibResource before you call OpenLinkedLib or OpenLib to make sure that a “new” library descriptive name does not already exist. It is your responsibility to make sure that the names used to access resources are unique, the Library Manager does not check.

Library File Type

When the Library Manager creates a new file it assigns it type LMIR. Likewise, when you look for a file using the standard file dialog, it will only show you files of type LMIR. This can be modified according to your application’s requirements.

The Nitty Gritty of Tracking Things

The routines work with new roms or old roms, HFS or MFS volumes (or any mixture);

In order to actually install a LMIR resource, the user (or developer) is guided by the application through the Standard File Package.

In order to maintain compatibility between HFS and MFS, Apple fixed things so that the Standard File returns a working directory number instead of a volume reference number. The important thing about working directory numbers is that they are created on the fly and they are strictly temporary and relative to a particular session.

What is needed is to turn the working directory number into a Volume Name and a Directory ID. The procedure that does this is GetPathInfo. When a file needs to be opened, the procedure OpenWD creates a new working directory for the file from this information. This new working directory number is then passed to FSOpen as the volume reference. If the volume is MFS and not HFS, OpenWD simply returns the volume number instead of a working directory and FSOpen is still happy.

File IO on Open Files

The File reference number for an opened file is stored in the LMIR record. There are also fields to maintain information on file type, total records, current record number. You can, of course, add other fields to your LMIR definition (or remove some of mine).

The Program Lib Mgr Demo..

...does a minimum three things

1) It looks for mythical “application default” and “user default” library files.

2) It tells you the status of the files: Opened, Closed, NotFound.

3) It waits for you to press the mouse button and then closes the files (if any are open).

The first time you run the program it will prompt you to find or create the two files mentioned above. If you satisfy these requests, the next time it will simply open the files without your intervention. To see how the program handles various problems, try moving, deleting, renaming, dismounting one or both files and rerunning the program.

The program was developed in LightSpeed Pascal. If you are using something other than LightSpeed, remove the DisplayMsg procedure and use the DisplayMsg2 procedure.

The only resource that the file needs is an alert dialog, ID = 301 and its associated item list. If you run the program in Lightspeed project mode, make sure you use a project resource file, or the “current resource file” the LMIR resources will be added to will be your system file!

One last thing: this code will need to be modified to fit your particular needs. The Library Manager I’ve presented is meant to be suggestive, not definitive. I’m sure that you will have to make changes for your own application environment(s). But it will give you a good base to work from. Toward this end, direct access to procedures not specifically mentioned in this article is provided in the interface portion of the LibMgr unit.


The HFSRunning and NewRoms came from a utilities package developed by David O’Rourke that is in the public domain. Thanks, Dave!
