1What's here? 2 3Each C file in this directory are heavily commented examples that illustrate 4only one or two S-Lang features. Some C files are accompanied by a .sl file 5that contains S-Lang code relevant to the example. 6 7If you find these demos confusing, please let me know so I can work on 8improving them. 9 10Please note that these demos WILL NOT WORK under msdos unless the S-lang 11library is compiled with the -DFLOAT_TYPE option. 12 13--------------------------------------------------------------------------- 14pager.c: A simple file pager demo. Use pageup/down keys to scroll 15 through the file. It illustrates the SLsmg, SLsig, SLkp, 16 and SLscroll routines of the S-Lang library. This example 17 should be contrasted with the curses demo ../src/curses/view.c. 18 19keypad.c: Illustrates the slkeypad facility. 20 21simple.c: This file contains slightly more than the miniumum required to 22 embed S-Lang. It loads a file specified on the command line. 23 24simple.sl: An S-Lang script that prompts for a filename and returns 25 information about the file. Use this with the `simple' 26 executable. 27 28array.c: This example shows how to embed a C array into S-Lang allowing 29 access to the array from a S-Lang script. 30array.sl: This script reads and writes the array specified in array.c. 31 32useropen.c This example shows how to specify an object that S-Lang will 33 interpret. S-lang already knows how to interpret code contained 34 in strings and files. Interpreting code from a `readline' 35 structure is illustrated here. The demo in ../src/calc.c uses 36 this technique to interpret data from S-Lang's readline routines. 37 38complex.c Adding an application defined data type is the focus of this 39 example. Specifically, a complex number type is added and the 40 binary and unary operators are overloaded to work with the new 41 type. 42complex.sl A script that manipulates the complex number type defined in 43 complex.c. 44
