+
+ Change the handling of the symbols in the skeletons.
+ Before we were using tables which lines were the symbols and which
+ columns were things like number, tag, type-name etc. It is was
+ difficult to extend: each time a column was added, all the numbers had
+ to be updated (you asked for colon $2, not for "tag"). Also, it was
+ hard to filter these tables when only a subset of the symbols (say the
+ tokens, or the nterms, or the tokens that have and external number
+ *and* a type-name) was of interest.
+
+ Now instead of monolithic tables, we define one macro per cell. For
+ instance "b4_symbol(0, tag)" is a macro name which contents is
+ self-decriptive. The macro "b4_symbol" provides easier access to
+ these cells.
+
+ * src/output.c (type_names_output): Remove.
+ (symbol_numbers_output, symbol_definitions_output): New.
+ (muscles_output): Call them.

+
+ Add %precedence support.
+ Unfortunately it is not possible to reuse the %prec directive. This

+
+ is ambiguous: either a rule which precedence is that of baz, or a rule,
+ and then a declaration of the precedence of the token baz.
