Library development
« on: May 03, 2007, 12:56:39 AM »

Just a quick update: this weekend I'll start backporting some of the libraries from Toka. Expect to see the following in the near future:

- floating point stack + basic operations (hybrid, C and Forth)
- sockets library (hybrid, C and Forth)
- time (basic functions to get time and date, time functions, etc)
- strings (probably not complete, but a good chunk of what Toka provides)

Some links to documentation on the library modules I'm porting:

- Strings: http://charleschilders.com:9812/book/stringslibrary.html
- Floats: http://charleschilders.com:9812/book/floatslibrary.html
- Time: http://charleschilders.com:9812/book/timelibrary.html
- Sockets: http://charleschilders.com:9812/book/socketlibrary.html

Edit: updated the links

Here is the code for creating and working with Toka-style arrays in RetroForth:

Code:

: is-array create allot ;
: get-element swap 4 * + @ ;
: put-element swap 4 * + ! ;
: get-char-element swap 1 * + c@ ;
: put-char-element swap 1 * + c! ;

A dummy definition for chars may be helpful in improving readability:

Code:

self: chars ;

The array words are documented at http://charleschilders.com:9812/book/arrays.html

The floating point support from Toka has been ported to RetroForth now. You can find it at http://charleschilders.com/retroforth/library

You will need floats.c and floats. Instructions for compiling floats.c are in the file itself. This library is documented at http://charleschilders.com:9812/book/floatslibrary.html

Next up: sockets
