- This directory contains WKSH OPEN LOOK example scripts. Here is a short
- explanation of the programs. None of the programs is really robust
- enough to be a final product at this time, and some features of some
- programs are not implemented. These are provided simply to show some
- typical WKSH programming techniques. Also, some of these programs
- have hard-coded colors and fonts, which is not recommended for robust
- product quality programs (resource files should be used instead).
-
- ammort
- Calculates fixed-interest loan ammortization schedules.
- wcalc
- A 4-function calculator with memory, square, square-root and
- reciprocal. Does the math by spawning calls to awk.
- wcalen
- A simple calendar application. Has "week at a glance", shows
- current day's events by default, can view months. Has the
- ability to schedule recurring events ("Meeting every Tuesday").
- Spawns calls to "cal" to figure out dates. Stores
- events in $HOME/calendar directory, one file per day. Needs
- some method to delete old entries after a certain amount of
- time, and needs a search feature to be really usable.
- helloworld
- The traditional UNIX System example program.
- lander
- Play the game of "Luner Lander". Land your luner module, and
- if your velocity is less than 10 m/s you don't explode and die
- a firey death.
- wkcmd, *.opts
- The wkcmd script takes as one of its arguments one of the
- *.opts files and provides a simple interface to a UNIX
- command with options. Other options files can be written
- to provide other simple interfaces. Basically, it parses
- the options file to produce a property sheet, and when
- requested will execute a UNIX command with the appropriate
- options and show the results. Because some UNIX System
- commands are not well behaived in their use of options, this
- does not always work out. For example, on some systems
- "wc -lc" works but "wc -l -c" does not. Also, the options
- files are for System V, ps(1) takes different options on
- other systems, etc.
- procs
- An example of creating an interface to a UNIX System command
- (ps).
- sampler
- Most widgets in haphazard fashion.
- timer
- A simple stopwatch style program.
-
- progguide*
- The examples from the WKSH for OPEN LOOK Programmer's Guide,
- in the order that they are presented. The number following
- the string progguide indicates the Chapter 3 figure number.
- So, progguide6 is Chapter 3 - Figure 6.
-
- attach.c
- This is a trivial example of a user-attachable command.
- This will only work on systems with Dynamic Shared Objects,
- like SunOs 4.1 or SVR4, but not SVR3 or earlier versions.
-
- On a SVR4 system, you can compile this into a shared
- object by using the following command line:
-
- cc -G -K PIC -o libattach.so attach.c
-
- On SunOs 4.1 or later you make this a shared object
- by doing:
-
- cc -c -PIC attach.c
- ld -o libattach.so attach.o
-
- Then, from within WKSH, you can execute:
-
- libload ./libattach.so
- cmdload argprint
-
- And then you can just start using argprint as a ksh
- built-in command.
-
- Note that ./libattach.so is necessary because the dynamic
- library commands need a "full" path to find the library
- if it's not in /usr/lib or in your $LD_LIBRARY_PATH.
