cpan/libmarpa/dev/api.texi<https://github.com/jeffreykegler/Marpa--R2/blob/master/cpan/libmarpa/dev/api.texi> [1] says it "typically indicates an application error", so internals are less likely.
[1] @deftypevr Macro int MARPA_ERR_INACCESSIBLE_TOKEN This error code indicates that indicates that the token symbol is an inaccessible symbol --- one which cannot be reached from the start symbol. Since the inaccessibility of a symbol is a property of the grammar, this error code typically indicates an application error. Nevertheless, a retry at this location, using another token ID, may succeed. At this writing, the author knows of no uses of this technique. Numeric value: 18. Suggested message: "Token symbol is inaccessible". @end deftypevr On Sat, Jan 18, 2014 at 3:45 PM, Durand Jean-Damien < [email protected]> wrote: > Jeffrey, > > Another question: > > Is the message "Problem in u_read(), alternative() failed: Token symbol > is inaccessible at /usr/local/lib/perl/5.18.2/Marpa/R2/SLR.pm line 881" > expected to be a problem in the user's grammar or in the SLIF internals ? > > This is with 2.07901. > > Thanks / JD. > > -- > You received this message because you are subscribed to the Google Groups > "marpa parser" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > For more options, visit https://groups.google.com/groups/opt_out. > -- You received this message because you are subscribed to the Google Groups "marpa parser" group.
