errors in generated go files

[K Richard Pixley]

I'm currently working with pigeon, a peg based parser generator.

When I...

• make a go error in the source file, grammar.peg...
• that is processed correctly by pigeon into an invalid grammar.go...
• and the go compiler correctly complains about the error...
• it complains about an error in grammar.go.

I wish it complained about the error in grammar.peg, with line number, and possibly column number.

I know how lex/yacc/byacc/bison/et all do this in C, (preprocessor statements).

How does one do this in go?

Maybe this helps?
