FKEY Programming Tools

By Mark A. Gruenberg, Miami, FL

Programming Tools: What are they?

[Mark A. Gruenberg is currently working on his Master's degree and intends to continue working until he gets his Ph.D. in Electrical Computer Engineering.-ed]

Programming tools aid developers in the development and maintenance of software. There are many examples of programming tools available for the Macintosh such as: TMON, a debugger; ResEdit, a resource builder; Prototyper, user interface builder; MACYACC, a language builder.

THINK C Integrated Environment

Accessing programming tools in THINK C’s integrated development environment is very clumbersome. Unlike Apple’s MPW environment, THINK doesn’t provide developers with facilities to readily develop and access custom programming tools.

FKEYs as Tools in LS Environment

An alternative for implementing programming tools in the THINK C environment is an FKEY resource. An FKEY or function key is a self contained code resource. No parameters are passed to an FKEY from the stack. It operates totally independent from the application which it was called from.

An FKEY is activated from the key board by typing command-shift-# (any number 0-9) keys all at the same time. Since no parameters are passed to the FKEY, a method of communication between the FKEY and the calling program must be devised. One method is, parameters can be passed to an FKEY by storing them in a memory location known by both the calling program and the FKEY. This brings to mind the low memory globals, specifically the Scrap Handle.

In the THINK C environment, the programmer can cut a section of data from a source code listing and pass it to the FKEY via the Scrap Handle for further processing. The FKEY then stores the new processed data back into the Scrap. Back in the THINK C environment the processed data can be accessed by pasting it into the source code. This is the method I will use to communicate between the FKEY and the THINK C environment.

Tools: Automating C Programming Guidelines

The process of writing source code in accordance with acceptable source code guidelines can be vary mechanical and time consuming. This is an excellent candidate for automation. For an excellent book on C Programming Guidelines see a book by the same title written by Thomas Plum.

The Guidelines

The guideline called Lexical Rules for Variables, taken from Plum’s book (See the book titled, “C Programming Guidelines,” pg. 2, by Thomas Plum.) is an excellent candidate for automation. The following is a description of the parts of the guideline which can easily be automated.

STANDARD 1.1exdata

All variable names, external and other names, be alphabetized by name within type.

JUSTIFICATION

This guideline improves the readability of the source code, thus lowering maintenance cost (the cost of maintaining and updating software).

Scrap and FKEYs

The scrap is used in Macintosh’s Operating System to store data that is cut and pasted within or between applications. There are two types of scrap, desk scrap and private scrap. Desk scrap can be used to transfer data between two applications, between an application and a desk accessory, or between two desk accessories. In other words, the desk scrap is available globally in the Macintosh’s operating system. Private scrap is used to store data which is cut and pasted within an application. Private scrap is only accessible within the application that created it. TextEdit scrap is an example of a private scrap used by the TextEdit manager.

The THINK C editor uses TextEdit to manage text formatting and editing. Because of this, the scrap we are interested in is a private scrap, the TEScrap. The FKEY can access the calling program’s private scrap (the TEScrap) using the TextEdit manager functions TEScrapHandle and TEGetScrapLength (For more information on TextEdit scrap see, “Inside Macintosh,” pg. I-373, 378). These functions return data stored in the low memory globals. Because an FKEY is called from GetNextEvent trap, the system is in a stable state. No context switching has taken place and the applications low memory globals are still intact. Thus, the FKEY is able to access the calling applications TEScrap.

Limitations of FKEYs

An FKEY can not use global variables including the QuickDraw globals. Upon entry into the FKEY, register A5 is set up to address the globals of the calling program. If we inadvertently defined and used a global variable named, glob_long= 5L; the long word value 5 would be placed at location -4(A5). This would destroy the data at this location, which most likely would be the calling application’s global variables.

An FKEY can not be segmented and must be less then 32K. The 32K size includes the size of the code and data for the FKEY.

The resource manager is not configured to allow FKEYs can own their own resources. Therefore, resource copying programs and installer programs will not know about the FKEYs associated resources.

Caveats

We can reference QuickDraw globals by using the low-memory global variable, CurrentA5. CurrentA5 points to the QuickDraw variable thePort, the rest of the QuickDraw globals can be addressed as negative offsets from CurrentA5.

THINK C’s assembler allows for the use of program global variables in code resources. To accomplish this you must assemble your project as a code resource, and call the following two functions immediately after main(): RememberA0() and SetUpA4(). These two functions set A4 to point to the beginning of the code resource, where the code resource expects to find the globals. The globals are then addressed off register A4. When exiting a code resource, the values of registers must be returned to their original state. The function RestoreA4(), does this and must be called before the code resource exits.

Resources can be used with an FKEY but it is the responsibility of the user to load the FKEY’s associated resources into the target destination. Therefore, the programmer should take steps to verify that the FKEY’s resources are available before allowing the FKEY to execute and crash.

Figure 1. compares the rate of growth of standard functions.

Sorting

I wanted to use an uncommon sorting algorithm. The algorithm I came up with is called the shell sort after its inventor Donald L. Shell. This algorithm is the fastest of the simple sorting algorithms. The only algorithm faster than the shell sort is the quick sort. The shell sort has a complexity of n1.2, the quick sort is nlogn (see figure 1). Do to the overhead involved in the shell sort it proved to be very inefficient for small number of elements. Since the sorting tool will generally be used to sort small lists the bubble sort proved to be more efficient.

I have included an implementation of the shell sort in the source code listing. Below is an explanation of how the shell sort works. I think you will find the shell sort very interesting and worth your time.

Figure 2. illustrates the shell sort sorting process.

The shell sort is an adaptation of the insertion sort, and is based on diminishing increments. It works by dividing the records to be sorted, r, into groups. The groups are determined by an internal sequence, h, which controls the distance between the records to be compared. Each of the records, r, and r[hs] are compared and swapped, if r > r[hs]. This process is repeated until all the sequences in h have been used. The sorting tends to converge quickly because the records are well ordered. The sorting process has been diagramed in figure 2 for the sequence, h={1,2,3,5,9} and the records r={6,4,1,3,2,5}.

The proper choice of the sequence, h, can significantly reduce the sorting time. Choosing this sequence has been a challenged for computer scientists and to this day we only have empirical data to base a choice of h on. This empirical data shows that it is reasonable to chose h in the following way:

h[1]=1, h[s+1]=3h[s]+1, and stop when h[t+2]   N

Where t, is the current value of the sequence counter, and N, is the number of records to be sorted.

Using the FKEY

Copy the lines of text you wish to be sorted. Then execute the FKEY by typing command-shift-# (FKEY number). If no error occurs, then the sorted lines of text can be pasted back into the selection.

If an error did occur and the FKEY’s resource file is available, an alert will be displayed describing the type of error. If the resource file is not available or there is not enough memory for the alert then a beep will be used to indicate an error.

Installing the FKEY

The FKEY can be installed using ResEdit. You must also remember to install the FKEY’s resources (‘ALERT’ and ‘DILT’). The FKEY can be installed into the system file or an application file. If the FKEY is installed into the system file, it will be available to be used system wide. If it is installed into an application it can only be accessed from the application it was installed into. The later method of installation is probably the most desirable.
