Denny + + doc: clean up naming of various Bison files. + The Bison manual's names for various files associated with a Bison + parser has devolved into inconsistency. This patch makes the + naming consistent for the most important files. First, it chooses + "grammar file" over "input file". The former appears to be more + traditional in the Bison manual, and Bison has other input + files (skeletons). Second, it chooses "parser implementation + file" over names like "parser file", "parser source file", "parser + source code file", and "parser output file". The new name makes + it clearer where Bison generates the main parser implementation, + and it is easily distinguishable from "parser header file". + * doc/bison.texinfo: Implement throughout. + +2011-02-06 Joel E. Denny + + doc: give credit to more of Bison's developers. + * doc/bison.texinfo (Introduction): Don't imply that only Robert + Corbett, Richard Stallman, and Wilfred Hansen have contributed to + Bison.

Denny + + doc: document experimental features better. + * doc/bison.texinfo (Introduction): Say that IELR(1) and canonical + LR(1) are experimental. Mention Java. Normally experimental + features probably shouldn't be mentioned in the introduction. + However, if Bison's limitations to LALR(1), C, and C++ are so + important that they should be mentioned here, then it's important + to point out that Bison is beginning to escape those limitations. + Moreover, these particular experimental features have very little + chance of being removed. + * src/getargs.c (usage): Say that IELR(1) and canonical LR(1) are + experimental. + +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.

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.
