What's here?
Each C file in this directory are heavily commented examples that illustrate
only one or two S-Lang features. Some C files are accompanied by a .sl file
that contains S-Lang code relevant to the example.
If you find these demos confusing, please let me know so I can work on
improving them.
Please note that these demos WILL NOT WORK under msdos unless the S-lang
library is compiled with the -DFLOAT_TYPE option.
---------------------------------------------------------------------------
pager.c: A simple file pager demo. Use pageup/down keys to scroll
through the file. It illustrates the SLsmg, SLsig, SLkp,
and SLscroll routines of the S-Lang library. This example
should be contrasted with the curses demo ../src/curses/view.c.
keypad.c: Illustrates the slkeypad facility.
simple.c: This file contains slightly more than the miniumum required to
embed S-Lang. It loads a file specified on the command line.
simple.sl: An S-Lang script that prompts for a filename and returns
information about the file. Use this with the `simple'
executable.
array.c: This example shows how to embed a C array into S-Lang allowing
access to the array from a S-Lang script.
array.sl: This script reads and writes the array specified in array.c.
useropen.c This example shows how to specify an object that S-Lang will
interpret. S-lang already knows how to interpret code contained
in strings and files. Interpreting code from a `readline'
structure is illustrated here. The demo in ../src/calc.c uses
this technique to interpret data from S-Lang's readline routines.
complex.c Adding an application defined data type is the focus of this
example. Specifically, a complex number type is added and the
binary and unary operators are overloaded to work with the new
type.
complex.sl A script that manipulates the complex number type defined in
complex.c.
