Re: Free Ada parser

[Craig Carey <research@ijs.co.nz>]

PS. Has anyone got an Ada Windows GUI program that can have embedded into
it, a user program ?. I.e. it would be like CMD.EXE, except:
 (1) it is a GUI program, and
 (2) all mouse drag selecting selects to the end of lines (and it does
     not select rectangles).
Gwindows code would be acceptable.

I uploaded a package that has merged Ada Yacc parser lines. It has a demo
program that makes of the Adagoop program. The demo program reads input
from the console and converts input to a tree and it parses it:

A new demo program showing use of Adagoop (it parses algebra expressions
read from the console (in Windows NT+)):

Adagoop:   http://www.usafa.af.mil/dfcs/bios/mcc_html/ada_stuff.html

Adagoop is extensively used. 
Two other documents uses are:
  * the Ada to Lego Mindstorms programming environment,
  * the A# program that ports Ada to the Microsoft .NET Platform:

Would the European Space Agency be using Ada 95 for the parser?.

There is another Yacc grammar file for Ada 95, amongst the SCATC files:

I did not test and use Opentoken because of its modified GPL licence.
Since not having looked at it, I don't know how it compares with the
USAFA Adagoop software.
