RE: [Boost-users] Fw: Parser error from semantic actions

Hermann Oliveira Rodrigues wrote:

How can I inform an error from a semantic action? Consider the following code:

rule = IDENTIFIER[ callback_a( m_varBinder, &VarBinder::bind ) ];

callback_a is an actor allowing member calls in semantic actions. VarBinder::bind receives an identifier and try to locate it in an external symbol table. If bind fails, I like to inform a parser error back to Spirit. How can I do that? Pointers to the relevant parts in the documentation are welcome.

Have you had a look at the error handling parsers (see here: http://tinyurl.com/5z2y6)? Regards Hartmut
