= 3.0.1 / 2014-03-14
* Fixed bad 3.0.0 release.
= 3.0.0 / 2014-03-14
* Moved Object#grammar to citrus/core_ext.rb. Citrus no longer installs core
extensions by default. Use "require 'citrus/core_ext.rb'" instead of
"require 'citrus'" to keep the previous behavior.
* Removed Match#method_missing, added #capture(name) and #captures(name)
Match#method_missing is unsafe as illustrated in Github issue #41. In
particular, it makes composing a grammar with aribitrary gems unsafe (e.g.
when the latter make core extensions), leads to unexpected results with
labels match existing Kernel methods (e.g. `p`), and prevents Match from
getting new methods in a backward compatible way. This commit therefore
removes it.
In Citrus 2.x, method_missing allowed rule productions to denote captured
matches by label name:
rule pair
(foo ':' bar) {
[foo.value, bar.value]
Also, it allowed invoking String operators on the Match's text:
rule int
[0-9]+ { to_i }
Those two scenarios no longer work out of the box in Citrus 3.0. You must
use capture(label) for the former, and to_str for the latter:
rule pair
(foo ':' bar) {
[capture(:foo).value, capture(:bar).value]
rule int
[0-9]+ { to_str.to_i }
Match#captures now accepts an optional label name as first argument and
returns the corresponding array of matches for that label (useful in case
the label belongs to a repetition).
= 2.5.0 / 2014-03-13
* Inputs may be generated from many different sources, including Pathname and
IO objects (thanks blambeau).
* Matches keep track of their offset in the original source (thanks
* Citrus.load no longer raises Citrus::LoadError for files that can't be found
or are not readable. Users must rescue Errno::ENOENT instead, for example.
* Removed a few ruby warnings (thanks tbuehlmann)
= 2.4.1 / 2011-11-04
* Fixed a bug that prevented rule names from starting with "super".
* Several minor bug fixes.
= 2.4.0 / 2011-05-11
* Fixed a bug that prevented parsing nested blocks correctly (issue #21).
* Added URI example.
* Moved example grammars inside lib/citrus/grammars and added
lib/citrus/grammars.rb for easily requiring Citrus example grammars.
= 2.3.7 / 2011-02-20
* Fixed a bug that prevented forward slashes from being used inside character
class literals.
* Added email address example.
= 2.3.6 / 2011-02-19
* Fixed a bug that prevented memoization from advancing the input's pointer
properly (thanks joachimm).
* Several additions to the TextMate bundle (thanks joachimm).
= 2.3.5 / 2011-02-07
* Fixed a bug that prevented Match objects from being printed properly using
Kernel#puts (thanks joachimm).
* Fixed a bug that prevented using rules with names that begin with "end"
(thanks Mark Wilden).
* Citrus#require accepts relative file paths, in addition to absolute ones.
* Simplified/cleaned up some example files.
= 2.3.4 / 2011-01-17
* Added CHANGES file.
= 2.3.3 / 2011-01-17
* Added self to Match#captures hash. This means that a Match may retrieve a
reference to itself by using its own label, proxy name, or index 0 in the
* Match#captures returns an empty array for unknown Symbol keys, coerces
String keys to Symbols, and returns nil for unknown Numeric keys.
* Moved Citrus::VERSION to its own file.
* Citrus::LoadError is raised when Citrus is unable to load a file from the
file system because it cannot be found or it is not readable.
* Citrus::SyntaxError is raised when Citrus::File is unable to parse some
Citrus syntax.
* Added Citrus.require for requiring .citrus grammar files in a similar way
to Ruby's Kernel.require. Also, overloaded the require operator in Citrus
grammar files to failover to Citrus.require when Kernel.require raises a
* Improved UTF-8 support.
