  • Added a bunch of tests for regexp escape chars, #parse_string, #read_escape, ? numbers, ? whitespace.

  • Added a hack for rubinius’ r2l eval bug.

  • Added a new token type tSTRING that bypasses tSTRING_BEG/END entirely. Only does non-interpolated strings and then falls back to the old way. MUCH cleaner tho.

  • Added bin/ruby_parse

  • Added compare rule to Rakefile.

  • Added coverage files/dirs to clean rule.

  • Added file and line numbers to all sexp nodes. Column/ranges to come.

  • Added lex_state change for lvars at the end of yylex.

  • Added lexed comments to defn/defs/class/module nodes.

  • Added stats gathering for yylex. Reordered yylex for avg data

  • Added tSYMBOL token type and parser rule to speed up symbol lexing.

  • Added tally output for getch, unread, and unread_many.

  • Added tests for ambigous uminus/uplus, backtick in cmdarg, square and curly brackets, numeric gvars, eos edge cases, string quoting %<> and %%%.

  • All cases throughout yylex now return directly if they match, no passthroughs.

  • All lexer cases now slurp entire token in one swoop.

  • All zarrays are now just empty arrays.

  • Changed s(:block_arg, :blah) to :“&blah” in args sexp.

  • Cleaned up lexer error handling. Now just raises all over.

  • Cleaned up read_escape and regx_options

  • Cleaned up tokadd_string (for some definition of cleaned).

  • Converted single quoted strings to new tSTRING token type.

  • Coverage is currently 94.4% on lexer.

  • Done what I can to clean up heredoc lexing… still sucks.

  • Flattened resbodies in rescue node. Fixed .autotest file.

  • Folded lex_keywords back in now that it screams.

  • Found very last instanceof ILiteralNode in the code. haha!

  • Got the tests subclassing PTTC and cleaned up a lot. YAY

  • Handle yield(*ary) properly

  • MASSIVELY cleaned out =begin/=end comment processor.

  • Massive overhaul on Keyword class. All hail the mighty Hash!

  • Massively cleaned up ident= edge cases and fixed a stupid bug from jruby.

  • Merged @/@@ scanner together, going to try to do the same everywhere.

  • Refactored fix_arg_lex_state, common across the lexer.

  • Refactored new_fcall into new_call.

  • Refactored some code to get better profile numbers.

  • Refactored some more #fix_arg_lex_state.

  • Refactored tail of yylex into its own method.

  • Removed Module#kill

  • Removed Token, replaced with Sexp.

  • Removed all parse_number and parse_quote tests.

  • Removed argspush, argscat. YAY!

  • Removed as many token_buffer.split(//)‘s as possible. 1 to go.

  • Removed begins from compstmts

  • Removed buffer arg for tokadd_string.

  • Removed crufty (?) solo ‘@’ token… wtf was that anyhow?

  • Removed most jruby/stringio cruft from StringScanner.

  • Removed one unread_many… 2 to go. They’re harder.

  • Removed store_comment, now done directly.

  • Removed token_buffer. Now I just use token ivar.

  • Removed use of s() from lexer. Changed the way line numbers are gathered.

  • Renamed *qwords to *awords.

  • Renamed StringScanner to RPStringScanner (a subclass) to fix namespace trashing.

  • Renamed parse to process and aliased to parse.

  • Renamed token_buffer to string_buffer since that arcane shit still needs it.

  • Resolved the rest of the lexing issues I brought up w/ ruby-core.

  • Revamped tokadd_escape.

  • Rewrote Keyword and KWtable.

  • Rewrote RubyLexer using StringScanner.

  • Rewrote tokadd_escape. 79 lines down to 21.

  • Split out lib/ruby_parser_extras.rb so lexer is standalone.

  • Started to clean up the parser and make it as skinny as possible

  • Stripped out as much code as possible.

  • Stripped yylex of some dead code.

  • Switched from StringIO to StringScanner.

  • Updated rakefile for new hoe.

  • Uses pure ruby racc if ENV, otherwise use c.

  • Wrote a ton of lexer tests. Coverage is as close to 100% as possible.

  • Wrote args to clean up the big nasty args processing grammar section.

  • lex_strterm is now a plain array, removed RubyLexer#s(…).

  • yield and super now flatten args.

• 21 bug fixes:

  • I’m sure this list is missing a lot:

  • Fixed 2 bugs both involving attrasgn (and ilk) esp when lhs is an array.

  • Fixed a bug in the lexer for strings with single digit hex escapes.

  • Fixed a bug parsing: a (args) { expr }… the space caused a different route to be followed and all hell broke loose.

  • Fixed a bug with xn=beginvar not putting begin back.

  • Fixed attrasgn to have arglists, not arrays.

  • Fixed bug in defn/defs with block fixing.

  • Fixed class/module’s name slot if colon2/3.

  • Fixed dstr with empty interpolation body.

  • Fixed for 1.9 string/char changes.

  • Fixed lexer BS wrt determining token type of words.

  • Fixed lexer BS wrt pass through values and lexing words. SO STUPID.

  • Fixed lexing of floats.

  • Fixed lexing of identifiers followed by equals. I hope.

  • Fixed masgn with splat on lhs

  • Fixed new_super to deal with block_pass correctly.

  • Fixed parser’s treatment of :colon2 and :colon3.

  • Fixed regexp scanning of escaped numbers, ANY number is valid, not just octs.

  • Fixed string scanning of escaped octs, allowing 1-3 chars.

  • Fixed unescape for n

  • Fixed: omg this is stupid. ‘()’ was returning bare nil

  • Fixed: remove_begin now goes to the end, not sure why it didn’t before.
