Denny +2011-01-29 Joel E. Denny + + Do not allow identifiers that start with a dash. + This cleans up our previous fixes for a bug whereby Bison + discarded `.field' in `$-1.field'. The previous fixes were less + restrictive about where a dash could appear in an identifier, but + the restrictions were hard to explain. That bug was reported and + this final fix was originally suggested by Paul Hilfinger. This + also fixes a remaining bug reported by Paul Eggert whereby Bison + parses `%token ID -123' as `%token ID - 123' and handles `-' as an + identifier. Now, `-' cannot be an identifier. Discussed in + threads beginning at + , + . + * NEWS (2.5): Update entry describing the dash extension to + grammar symbol names. Also, move that entry before the named + references entry because the latter mentions the former. + * doc/bison.texinfo (Symbol): Update documentation for symbol + names. As suggested by Paul Eggert, mention the effect of periods + and dashes on named references. + (Decl Summary): Update documentation for unquoted %define values, + which, as a side effect, can no longer start with dashes either. + * src/scan-code.l (id): Implement. + * src/scan-gram.l (id): Implement. + * tests/actions.at (Exotic Dollars): Extend test group to exercise + bug reported by Paul Hilfinger. + * tests/input.at (Symbols): Update test group, and extend to + exercise bug reported by Paul Eggert. + * tests/named-refs.at (Stray symbols in brackets): Update test + group. + ($ or @ followed by . or -): Likewise. + * tests/regression.at (Invalid inputs): Likewise. + +2011-01-24 Joel E.

Denny + + Improve error messages for `$' or `@' followed by `.' or `-'. + Previously, for this special case of an invalid reference, the + usual "symbol not found in production:" was printed. However, + because the symbol name was parsed as the empty string, that + message was followed immediately by a newline instead of a symbol + name. In reality, this is a syntax error, so the reference is + invalid regardless of the symbols actually appearing in the + production. Discussed at + . + * src/scan-code.l (parse_ref): Report the above case as a syntax + error. Other than that, continue to handle this case like any + other invalid reference that Bison manages to parse because + "possibly meant" messages can still be helpful to the user. + * tests/named-refs.at ($ or @ followed by . or -): New test group. + +2011-01-08 Joel E.
