Walrus r80, 6 items changed
Return ArrayResult instances rather than Arrays to avoid polluting the Array namespace
Posted 4:36 PM
Walrus r79, 29 items changed
Massive changes under the hood to the location-tracking system requiring wide-reaching changes and re-writes of almost all the core classes: get rid of OmissionData class (omitted data really is omitted now and not recorded anywhere, only the starting and ending line and column coordinates of the omission are taken into consideration and the data is then discarded); SkippedSubstringExceptions now include starting and endling line and column coordinates; ParseErrors now include coordinates; MemoizingCache now uses line and column coordinates instead of a single location index (position in input stream); no longer include "rightmost" subexception when raising a ParseError, instead just include coordinates; ParseError now encapsulates line and column start and end points instead of just "line_offset" and "column_offset"; ParseError now has a richer, human-friendly "inspect" method; the lowest level parslets (StringParslet and RegexpParslet) now do full coordinate tracking (line and column start and end points) rather than just offset tracking; generated Node subclasses no longer have an "omitted" accessor (in fact, the "omitted" accessor has been removed everywhere that it formerly appeared because omitted data is no longer retained); the skipping and location tracking code in many ParsletCombination subclasses has been made much "DRYer" by moving location tracking responsibility into the ParserState class; updated LocationTracking module to provide nil-friendly accessors and use absolute coordinates rather than offsets; new StringResult class (String subclass) enables coordinate accessors to be added to a class that behaves just like String, these objects can be returned as parse results and there is no need to clutter the String namespace with Walrus-specific methods; likewise for for Array, a new subclass called ArrayResult has been added (although it has not been "hooked up" yet); updated and added specs to match all this new/modified behaviour

Walrus r78, 3 items changed
Faster source string conversion method; new accessors for working with line_offset and column_offset concentrate all nil-handling into a single place
Posted 4:42 PM
Walrus r77, 4 items changed
Correct problems with 'rightmost' detection and storage
Posted 4:04 AM
Walrus r76, 12 items changed
Reworking location tracking storage: it now resides in parse results (or exceptions thrown during parse attempts) rather than being kept in instance variables on the parslets themselves; this allows the parslets to be kept re-entrant and suitable for use in threaded or recursive environments
Posted 3:40 AM
Walrus r75, 6 items changed
Specs for low-level parslet location tracking

Minor tweaks and cleanups to grammar rules for multi-line comments, and multi-line comments with nesting; more specs for the same
Posted 5:52 PM
Walrus r59, 2 items changed
Remove 'each_char' method (now provided by jcode library); shorter, faster implementation of 'chars' method; override '[]' method to transparently provide Unicode-awareness when passed a range instance (other cases may be useful in the future but were not added because they were not required to pass all the specs); simplify code in ParserState (possible due to overridden '[]' method)

Walrus r48, 89 items changed
Large-scale reorganization (nearly 4,000 lines of diffs): removing old hand-coded lexer and parser files obsoleted by the parser generator; centralize all 'require' and 'autoload' statements into a single overarching header file (saves a couple of lines or more in most files); move initialized into shared header and remove local overrides (cleaner code); use jcore library and jlength method for greater speed when determining the length of Unicode strings; initial implementation of ProcParslet class

'import' and 'include' directives; many specs for testing string literal parsing
Posted 1:52 PM
Walrus r20, 2 items changed
ParsletMerge should deal with omissions at the level of the collection, not the elements inside the collection (to match the behaviour of other parslet combinations); as a side effect this enables some grammar rules to be written less verbosely (for example, a factored out predicate rule preceded by whitespace that should be omitted, like the 'directive' rules in Walrus)

Dead comment removal
Posted 9:04 PM
Walrus r3, 20 items changed
All parse methods now expect an optional hash parameter containing options; when parse methods call other parse methods the hash is passed on, baton-style; this allows the continuation trick to be removed from the parse method and makes program flow a little more self-evident
