Blockers

• basic documentation
• detect erroneous rebinding of names

Laters

• complete support for void types: void start rule?
• fix nested seq in guards and/or make nested seq work
• fix check_redef() to not be O(n²)
• investigate allocating evlis statically (we can calculate its maximum size, but this may be much larger than is typically used, so static allocation won't necessarily save space, but i suspect in practice it's a win almost all the time)
• see if there's anything we can do about making * return a vector
• report errors in terms of sugared syntax
• implement s_free(). (We could use a flag in struct s_node to say if the text member came from malloc() or not.)
• autoconfiscation (later because I really want to make at least one more public release with my beautiful pristine makefile)
• packages for (at least) Fedora and Debian
• parser optimization
• value inheritance, so a rule like S ← t:That { t } / ... can instead be written S ← That / ...
• XXX cleanups
• review
• more research
• permissions (since I won't actually distribute the Java parser yet)
• worry a lot about memory management
• don't run the evaluation code till pacc_result() is called

Ongoing

• pore over the output of the compiler for improvements

Completed

Will be in the next release:

• support all C99 character escapes
• UTF-8 support in coordinates
• memoize _pacc_coords()
• bring pacc0.c up to date (character classes, right anchoring)
• UTF-8 support in character classes
• refactor Unicode reading code in any and cclass matchers
• make → 5 work
• warn about bad character classes
• pacc_error() now returns an error string, instead of outputting it
• there is a new pacc_pos() function
• check that all rules are reached
• YY_input() no longer takes a name parameter (but YY_wrap() does)
• YY_error() returns a string that doesn't include the name
• detect rules being redefined
• expose ability to alter prefix
• macro and variable to enable tracing
• move all names into the pacc_ / _pacc_ namespaces

Were in the pacc-0.0 (ronin) release:

• minimal documentation
• UTF-8 support in any matchers
• anchor all grammars left and right
• complete command line interface
• implement --feed / partialization (this is my unique selling point)
• scoping -- names in pacc grammars are supposed to scope statically over sequences, but that clearly isn't the case at the moment, otherwise test/pacc/scope1.pacc would compile!
• add #line directives
• detect left recursion
• one instance of each type per union
• dynamically allocate everything

Never forget

todo is Spanish for everything
