Ability to define two parsers from the same lexer #65

Open fish-face opened 3 years ago

fish-face commented 3 years ago

If you define a lexer niml lexer[MyToken] and then two parsers nimy parserOne[MyToken] and nimy parserTwo[MyToken] you get an error due to a redefinition of the function parse (parsegen.nim:1001)

@fish-face Thank you for the reporting! I won't fix this, but maybe I can help you.

nimy is designed as a macro to make the parsing table and define the function parse for the table. So, if you define two parse in one module (with the same token type), these names are conflicted.

But, you can use two (or more) different nimy parser in one module if you define two (or more) parsers in two (or more) other modules. https://github.com/loloicci/nimly/blob/master/tests/test_lr_lalr.nim is a good example to use two parsers in one module. (using https://github.com/loloicci/nimly/blob/master/tests/parser_415.nim and https://github.com/loloicci/nimly/blob/master/tests/parser_415_lr.nim) Does it solve your problem?
