As the people from University of Luebeck (now moved to the University
of Goettingen) don't have the time to maintain the TTCN3Parser, I
decided to rewrite it to fix some critical problems. I did not use
C++ and ANTLR, but Python and the PyParsing module for this. The new
version is in it's very early stages and has some major issues:
- speed: the performance is unbelievably bad
- error handling: in most cases, the error message points to a higher
level construct instead of the real problem
- no output: I did not yet implement a tree output function, '-t'
gives a pseudo-XML output of the parse tree
On the other hand, the new version follows the latest TTCN-3 standard.

Dear TTCN-3 developer,
great care has been taken to create a parser that reflects the TTCN-3
standard correctly and that produces abstract syntax trees (ASTs) which
can be evaluated easily.
But no software program is error-free! Hence,
WE NEED YOUR ASSISTANCE
to make this parser as good as possible. If you run the TTCN-3 parser,
we would like you to check the following issues:
- Does the TTCN-3 parser reject a correct TTCN-3 module?
- Does the tree parser (i.e. the AST analyzer) reject some AST?
- Does the TTCN-3 parser produce incorrect ASTs,
e.g. does it take a 'GetReplyStatement' for a 'ReceiveStatement'?
- Are line and column information erroneous?
- Do the ASTs contain superfluous nodes, i.e. nodes that blow up
the tree unnecessarily?
- Do the ASTs lack some nodes that you would like to see?
- Or would you like to have some nodes arranged in a different way?
If you feel like the parser behaves inadequately, please send a short email
to 'neukirchen@itm.uni-luebeck.de'. If possible, please also send us a TTCN-3
example that illustrates the deficiency.
Well, that's all we are asking for...
IT'S NOT TOO MUCH FOR A FREE TTCN-3 PARSER, IS IT?
Thanks in advance!
Michael Schmitt, Roman Koch, Jens Grabowski, Helmut Neukirchen
