I've been given the task of porting fairly large quantities of
Modula-2 code to C. If I am unsuccessful in finding a PD
translator for this purpose I am probably going to have to
work one up myself.
My question is: Is there a YACC/Bison grammar available anywhere
for Modula-2, that could be used as the basis for this project?
Thanks in advance,
George.
[If someone has such a grammar, I'd be happy to add it to the collection.

Though it is not PD, it is very cheap. A short description follows. Josef Grosch MTC(1) GMD-Forschungsstelle-Karlsruhe MTC(1) NAME mtc - Modula-2 to C translator DESCRIPTION Mtc translates Modula-2 programs in readable and therefore maintainable K&R C code without major restrictions (even nested procedures and modules). The translator is largely generated using the GMD compiler construction toolbox. It contains semantic analysis as far as needed for the task. Semantic analysis is rather complete and comprises scope handling, name analysis, and type determination. Context conditions are not checked, as it is assumed that only correct programs are processed. Mtc translates Modula-2 as defined in "N. Wirth: Programming in Modula-2, Third Corrected Edition, Springer-Verlag, 1985". RESTRICTIONS Coroutines are not implemented yet. Comments are lost. IMPLEMENTATION-LANGUAGES Modula-2 or C TARGET-PLATFORMS SUN 3 oder SUN 4 / SunOS DEC Station / ULTRIX VAX / ULTRIX oder BSD UNIX 4.2 PCS Cadmus / MUNIX others DISTRIBUTION Medium: DC 300 A data cartridge or TK 50 in tar format source program in Modula-2 as well as in C binary executable for SUN 3 CONTACT J.

Thanks to all who replied following my request for Modula-2 to C translators, or Modula-2 grammars. > I've been given the task of porting fairly large quantities of > Modula-2 code to C. If I am unsuccessful in finding a PD > translator for this purpose I am probably going to have to > work one up myself. The following reply (from Carl Witty <cwitty@cs.Stanford.EDU>) is typical: Dave Gillespie's p2c Pascal to C translator has a Modula-2 mode. It doesn't quite handle all of Modula-2's features, but it may be enough for you. It's available by anonymous ftp to csvax.cs.caltech.edu; the author is daveg@csvax.cs.caltech.edu. Several people also suggested looking at the Modula-3 compiler available on the net. There were no Modula-2 grammars forthcoming. Others who replied were: wilker@gauss.math.purdue.edu (Clarence Wilkerson) m2xenix!sequent.com!pasqnt!jfk (Jim Kerrigan) raymond@math.berkeley.edu (Raymond Chen) Pat.Terry@f4.n494.z5.fidonet.org Chris Siebenmann <cks@hawkwind.utcs.toronto.edu> Piet van Oostrum <piet@cs.ruu.nl> Troy Zerr <zerr@math.wisc.edu> wrote: Writing a reliable translator from Modula-2 to C is not particularly easy. Doing the translation by hand would almost certainly be quicker than writing a robust translator, and would probably be quicker than writing an unreliable translator and then manually fixing up the translated code. However, if you are interested, someone wrote a master's thesis on a Modula-2 to C translator. Hang on a sec ... The thesis was written by Matthias Martin at Karlsruhe, Germany. The thesis is titled "Entwurf und Implementierung eines Ubersetzers von Modula-2 nach C" and as the title would suggest, the thesis is in German.

There is a pascal to C translator knows as p2c which can be had from csvax.caltech.edu. It "knows" about Modula2 code but to what extent I don't know. You can mail the author, Dave Gillespie at daveg@csvax.caltech.edu for more info. What's more, it's PD. albert -- Send compilers articles to compilers@iecc.cambridge.ma.us or {ima | spdcc | world}!iecc!compilers. Meta-mail to compilers-request.
