David Majda	718bcf5f87	Rename the \|action\| property of action AST nodes to \|code\|	14 years ago
David Majda	95735f2c97	Allow trailing semicolon (";") for rules	14 years ago
David Majda	ee8c121676	Use labeled expressions and variables instead of $1, $2, etc. Labeled expressions lead to more maintainable code and also will allow certain optimizations (we can ignore results of expressions not passed to the actions). This does not speed up the benchmark suite execution statistically significantly on V8.

David Majda	52704593cd	Allow labeled expressions in the metagrammar (without any meaning yet)	14 years ago
David Majda	409ddf2ae8	Formatted all grammars more consistently and transparently This is purely cosmetical change, no functionality was affected (hopefully).	14 years ago
David Majda	698564a3c2	Replace ":" after a rule name with "=" I'll introduce labelled expressions shortly and I want to use ":" as a label-expression separator. This change avoids conflict between the two meanings of ":". (What would e.g. "foo: 'bar'" mean? Rule "foo" matching string "bar", or string "bar" labelled "foo"?)	14 years ago
David Majda	7fdf0492c7	Fixed error message for invalid character range + added test	14 years ago
David Majda	570658756a	Remove useless action from the metagrammar	14 years ago
David Majda	33a1a7c1e9	Clean up class handling in the metagrammar and compiler The class AST node now contains structured data and a raw text which is used for error messages.	14 years ago
David Majda	137a4b4f53	Renamed \|characters\| -> \|chars\| (shorter, no loss of expressivity)	14 years ago
David Majda	b4bf49443a	AST refactoring 5/6: Make AST classless	14 years ago
David Majda	4e99a2bda7	AST refactoring 1/6: Make properties of AST nodes public Removed undescore prefix of the properties and deleted getters.	14 years ago
David Majda	b2f230fad2	Added Optional AST node. This does not speed up the benchmark suite execution statistically significantly on V8.

David Majda	7fc491412d	Work around the fact that IE does not recognize "\v" in strings.	14 years ago
David Majda	e63f64a3d5	Make the generated parsers standalone (no runtime is required). This and also speeds up the benchmark suite execution by 7.83 % on V8.

David Majda	3291c70d97	Added \uFEFF (BOM) to the definition of whitespace in the metagrammar. The Rhino bug that prevented inclusion of \uFEFF among the whitespace characters is no longer relevant here because we compile character classes into regexps now, which avoids the infinite recursion.	14 years ago
David Majda	383c5acaa6	Replaced \xA0 by \u00A0 in the whitespace definition in the metagrammar. This is purely stylistic change.	14 years ago
David Majda	4f4bb34ded	Implemented negative character classes (e.g. [^a-z]).	14 years ago
David Majda	22d2ac8ac2	Rewrote implementation of classes to be regexp-based.	14 years ago
David Majda	6bbd88088b	Implemented and used PEG.ArrayUtils.each.	14 years ago
David Majda	a43d1b33e3	Bootstrapped the grammar parser, yay! I should have done this long ago.	14 years ago
