Hi

I tested T-gen with the following result:


INSTALLATION OF T-GEN

I downloaded the T-gen scanner/parser generator from the link
mentioned on
http://minnow.cc.gatech.edu/squeak/1419


http://coweb.cc.gatech.edu:8888/cs2340/uploads/tgen.zip

and installed it in a Squeak image 2.8a 2052 according to the
instructions in the ReadMe file.

Installation caused no Walkbacks.


TESTING T-GEN
1) 
When evaluating
TranslatorGenerator runAllTests
all tests failed.

The tests generate a scanner and a parser class in the category
'TGen-Interface'.
You have to remove them manually after a test failed. I evaluated the tests
individually as well with the same results.


2) 
After evaluating
TGenUI open
in Morphic and loading each examples manually I got the follwing results

ex 1 LL(1)  OK
ex 2 LL(1) OK
ex 3  LL(1)  OK
ex 4 LALR(1)  OK  
ex 5 LR(1)  OK
ex 6 LR(1); generation failed; nondeterministic parser available
ex 10 LL(1)  OK
(Make sure to choose 'any parser' in upper left pane in the GUI)

'OK' means a parse tree was generated which looked more or less like it
should
be. However I didn't do a thourough check.


I could imagine that a relatively small error makes all tests fail. However
I wasn't able
to spot an error.



QUESTIONS

Is the version of the T-gen port  mentioned above the latest one?

Do you have some suggestions / hints / changesets on fixing the problem?




Thanks in advance for your efforts
