Let's use c++/glr to demonstrate custom error messages in C++ (not just in glr2.cc). * examples/c++/glr/c++-types.yy (report_syntax_error): New. * examples/c++/glr/c++-types.test: Adjust. * examples/c/bistromathic/parse.y: Comment changes. * tests/local.at (AT_YYERROR_DEFINE(c++)): Use a nicer way to print the lookakead's name.

# glr

|
|
|
This example demonstrates the use of GLR parsers to handle (local)
|
|
ambiguities in the C++ language. See the node "Merging GLR Parses" in
|
|
Bison's documentation.
|
|
|
|
It uses (Bison) variants to store objects as semantic values. It also
|
|
demonstrates custom error messages in C++.
