BASIC-to-Euphoria - some inquiries
I'm currently working on converting some old BASIC code - mixed GW-BASIC
and Q-BASIC - to Euphoria. While investigating available tools, the
following questions have arisen:
(1) For David Cuny: The ebasic translator indicates that you've effectively
abandoned it, and you note in one of the readmes that were you starting the
project today, you'd take a different tack in the design. Unless you plan
to resurrect the project, I'm going to have to write a translator of my
own, as ebasic, even when presented with what I've been calling a
'Euphoria-clean' file, has some deficiencies in the generated code, and
lacks some support for some BASIC features. Given that, I'd be interested
in hearing what you have to say about the revised approach - or hearing
that you _haven't_ abandoned ebasic, and are on the verge of releasing an
update.
(2) Graphics: At last report, there were no Euphoria includes that would
provide a simple interface to graphics across all extant supported
platforms. If someone knows of one that does - and by 'simple', I mean at
the DOS graphics.e level, or perhaps implementing something similar to the
GW-BASIC/Q-BASIC graphics interface. If anyone can point me in an
appropriate direction, I'd be appreciative.
(3) An alternative to writing my own translator would be to use a tool that
could take structured definitions of the two languages, and be able to
convert one to the other. I _know_ that such tools exist, primarily for
UNIX platforms (including Linux), but enough are available in source form
that I could easily compile one for DOS. What I need for those tools,
though, is good definitions of the languages in question - meaning,
usually, either EBNF notation definitions, or 'railroad track' diagrams of
the language syntax. I'm pretty sure I can find definitions for
GW-BASIC/Q-BASIC; has anyone done one for Euphoria?
