[hoc-devel] TH debugging

[Daniel R. <da...@ph...>]

Greetings,

I thought I could write a cleaner version of expandSynonyms.  Then I  
discovered writing and verifying TH is hard!  So I wrote some code for  
debugging and testing TH functions.

There is a module now called HOC.THDebug that contains some useful  
printing methods.  In Tests there is also now a target thtests that  
compiles two files for testing expandSynonyms.  Because it is TH, the  
test actually runs from within the compiler.  To run the test, you  
compile the program.  thtests actually ensures that the compile is run  
every time.  If the compile succeeds, the test passed!  It needs work  
to be a real test harness, but I think it's something to build on.

Beyond that, runIO and the code in THDebug are tremendously useful for  
outputting intermediate results (during compile) of your TH code.
