nitcc add groups and small improvments #2839

Closed privat closed 2 months ago

privat commented 2 months ago

Add groups in the parser, that are anonymous productions enclosed by parenthesis.

foo = x (bar baz) y | z ;

is equivalent with

foo = x anon0 y | z ;
anon0 = bar baz ;

This becomes handy when combined with the modifies +, ? and *.

foo = x (bar baz)+ y | z ;

is equivalent with

foo = x anon0+ y | z ;
anon0 = bar baz ;

that is equivalent with

foo = x anon1 y | z ;
anon1 = anon1 anon0 | anon0 ;
anon0 = bar baz ;

Note: This PR is a fork of #2836
