Best practices for writing a programming language parser

Question

Are there any best practices that I should follow while writing a parser?

Answer 1

Few pieces of advice:

• Know your grammar - write it down in a suitable form
• Choose the right tool. Do it from within C++ with Spirit2x, or choose external parser tools like antlr, yacc, or whatever suits you
• Do you need a parser? Maybe regexp will suffice? Or maybe hack a perl script to do the trick? Writing complex parsers take time.
