Development of 9.3
« on: September 07, 2006, 03:14:06 AM »

I am now beginning to actively work on RetroForth 9.3. A short summary of some of the projected changes follows:

1. Vectors
All words for manipulating vectors can be used inside definitions now.
Some renamings have taken place:
is: --> replaced by is
default: --> replaced by is-default
now --> replaced by now?

2. Error handling when word is not found:
word? is now for displaying an error message. The old behaviour is replaced by (not-found)

3. Sections have been added.

Code:

section:
private data/definitions
export
public data/definitions.
;section

These are not nestable, but are cleaner than loc:/;loc in many situations.

4. Performance
I will be merging in some of the various optimized definitions sent to me.

5. ANS
I am working with Neal to make sure that a version of the ANS layer will function at least as well as it does under 9.2.10

6. Files
Will have better support than before. I am revamping most (if not all) of the file load/save/nested include code.

I will post more here as development progresses. Expect to see a repository opened up this weekend, once I am finished with the initial changes from 9.2.10.

At this point I have added sections (#3), the new vector code (#1), I dropped #2 (error handling changes) for now; it was proving highly problematic when moving existing code to 9.3.

With regard to compatibility: most 9.2.x programs will run without change. I have kept aliases/implementations of the old functions in modules/compat. These are marked with a class of .deprecated-<normal class name> and will be removed in a future release.

Things are mostly working. It currently fails to load some applications that use the ANS layer on Windows. (I have been unable to reproduce this on any of the other targets). With luck the problem will become apparent soon, and work on other areas can start again.

With regard to the Native port, I am almost done updating it to the 9.2.10 codebase. Public releases of both 9.3-development and Native 9.2.10 will be made soon.
