getting AST from yacc

Show all headers | View raw

I am a bit old and do not learn as well as in the past. I have a very
large yacc file that works fine.

What I want is to produce an AST tree from the yacc .y file. I have read
many things on the net

about this but they all start at too high a level for me to grasp.

Any help for an old slow old man (related to this problem)?

[The short answer is that yacc doesn't do that, but it's not hard to write action
code that builds a AST as it does the rule reductions.  If you can find a copy of
my "flex & bison" it has some examples that build AST. -John]
