After reading some more in Threaded Interpreted Languages (TIL_ from now on),
|
|
|
|
|
I've decided to start over.
|
|
|
|
|
|
|

.. _TIL: http://wiki.c2.com/?ThreadedInterpretiveLanguage

|
Some design choices that didn't really work out:
|
|
|
|
|
|
|
|
|
|
+ the system structure
|
|
|
|
|
+ not making it easier to test building for different platforms
|
|
|
|
|
+ my linked list approach to the dictionary
|
|
|
|
|
+ my class-based approach to words
|

I get the distinct feeling that I could (maybe should) be doing this in C99, so
|
|
|
|
|
I think I'll switch to that.
|
|

|
The new design
|
|
|
|
|
^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
I'll need to provide a few initial pieces:
|
|
|
|
|
|
|
|
|
|
1. eval.c
|
|
|
|
|
2. stack.c
|
|
|
|
|
3. the platform parts
|
|
|
|
|
|
|
|
|
|
I'll skip the parser at first and hand hack some things, then try to
|
|
|
|
|
port over my I/O layer from before.
