The user should think of yypcontext fields as accessible only via yypcontext_* functions. So let's rename yyexpected_tokens to reflect that. Let's _not_ rename yyreport_syntax_error, as the user may define this function, and is not allowed to access directly the fields of yypcontext_t: she *must* use the "accessors". This is comparable to the case of C++/Java where the user defines parser::report_syntax_error, not parser::context::report_syntax_error. * data/skeletons/glr.c, data/skeletons/yacc.c (yyexpected_tokens): Rename as... (yypcontext_expected_tokens): this. Adjust dependencies.
bistromathic - all the bells and whistles
This example demonstrates best practices when using Bison.
- Its hand-written scanner tracks locations.
- Its interface is pure.
- Its interface is "incremental", well suited for interaction: it uses the push-parser API to feed the parser with the incoming tokens.
- It features an interactive command line with completion based on the
parser state, based on
yyexpected_tokens. - It uses a custom syntax error with location, lookahead correction and token internationalization.
- It supports debug traces with semantic values.
- It uses named references instead of the traditional $1, $2, etc.
