= NEWS
This document is a list of user visible feature changes made between
releases except for bug fixes.
Note that each entry is kept so brief that no reason behind or
reference information is supplied with. For a full list of changes
with all sufficient information, see the ChangeLog file.
== Changes since the 1.8.7 release
=== Lexical changes
* empty symbol literal
Empty symbol (:"") is allowed.
* new hash immediates
Ruby 1.9 style hash syntax e.g. { key: value } is now supported.
Just like the normal hash syntax, you can put key-value pairs
without enclosing parentheses at the end of a method argument list.
e.g. some_method foo: 1, bar: 2
* new method invocation syntax
Ruby 1.9 style special method invocation syntax f.(x), which is
equivalent to f.call(x), is supported. This is mainly for use
in invoking a Proc.
* trailing comma in argument list
A trailing comma can be put at the end of an argument list.
e.g.
MyStruct = Struct.new(
:id,
:name,
:created_at,
:description,
)
=== Configuration changes
* version specific directories
A new configure option --with-ruby-version is added, which allows
user to specify the version string (defaulted to "1.8") for version
specific directories such as library directories, ri directories and
gem directories.
=== Library updates (outstanding ones only)
* global functions
* loop
Return an enumerator if no block is given.
* builtin classes
* Array#try_convert
* Hash#try_convert
* IO#try_convert
* Regexp#try_convert
* String#try_convert
New methods.
* Array#sample
New method which replaces #choice.
* Array#sort_by!
New method.
* Enumerable#each_entry
New method.
* Enumerable#each_with_object
* Enumerator#with_object
New methods.
* Enumerator.new { |y| ... }
Now can generate an enumerator from a block that defines
enumeration instead of an enumerable object.
* Enumerator#rewind
Now calls the "rewind" method of the enclosed object if defined.
* Enumerator#inspect
Implemented.
* Hash#default_proc=
New method.
* Hash#key
Renamed from Hash#index.
* Kernel#singleton_class
New method.
* ENV.key
Renamed from ENV.index.
* IO#ungetbyte
Added as an alias to #ungetc.
* Proc#===
New method primarily for use in the case-when construct.
* Process.daemon
New method.
* Range#cover?
New alias to #include? for the forward compatibility with 1.9, in
which the behavior of Range#include? has changed.
* Regexp
The regular expression /\s/ now properly matches a vertical tab
character (VT: "\v") and /\S/ does not. It was a bug that /\s/
did not match VT when /[\s]/ does. It is clear that VT should
always be regarded as white space, not to mention String#strip.
* String#getbyte
* String#setbyte
* String#ord
New methods for the forward compatibility with 1.9, in which the
behavior of String#[] and String#[]= have changed. String#ord is
$KCODE aware.
* Symbol#succ
* Symbol#next
* Symbol#<=>
* Symbol#casecmp
* Symbol#=~
* Symbol#[]
* Symbol#slice
* Symbol#length
* Symbol#size
* Symbol#empty?
* Symbol#match
* Symbol#upcase
* Symbol#downcase
* Symbol#capitalize
* Symbol#swapcase
New methods.
* base64
* Base64#strict_encode64
* Base64#strict_decode64
* Base64#urlsafe_encode64
* Base64#urlsafe_decode64
New methods.
* dbm
* gdbm
* sdbm
* {DBM,GDBM,SDBM}#key
Renamed from #index.
* digest
* Digest::Class.base64digest
* Digest::Instance#base64digest
* Digest::Instance#base64digest!
New methods.
* fileutils
* New option for FileUtils.rmdir(): :parents
* logger
* imported upstream version (logger/1.2.7)
* do not raise an exception even if log writing failed.
* do not raise ShiftingError if an aged file already exists.
(no ShiftingError will be raised from 1.2.7, just warn() instead)
* matrix
* API change to adhere strictly to mathematical definitions:
* Matrices must now be rectangular.
* trace, regular?, singular? are defined only for square matrices
* support for empty matrices
* all integer matrices now have the right determinant (also an integer)
* Matrix and Vector include Enumerable.
* new methods:
* Matrix.build
* Matrix.empty
* Matrix#each
* Matrix#each_with_index
* Matrix#empty?
* open-uri
* Added a lot of new options:
* :ftp_active_mode => bool
Specify false to enable FTP passive mode. It is adviced that
this option should be explicitly set for forward compatibility
because the default mode is changed in Ruby >= 1.9.
* :read_timeout => seconds
* :proxy_http_basic_authentication => [uri, user, password]
* :redirect => bool
* :ssl_verify_mode => OpenSSL::SSL::VERIFY_*
* :ssl_ca_cert => filename
* rational
* Performace improved by making overall code optimization and
introducing Fixnum#gcd implemented in C.
* rexml
* REXML::Document.entity_expansion_limit=
New method to set the entity expansion limit. By default the limit is
set to 10000. See the following URL for details.
http://www.ruby-lang.org/en/news/2008/08/23/dos-vulnerability-in-rexml/
* rss
* 0.2.4 -> 0.2.7.
* RSS::Maker.make
* raise an exception instead of returning nil for invalid feed making.
* requires block.
* RSS::Maker.[]
* new method to return maker class.
* RSS::Maker.supported?(version)
* new method to check if given version is supported.
* RSS::Maker: item.guid.permanent_link?
* new alias of item.guid.isPermaLink
* RSS::Maker: item.guid.permanent_link=
* new alias of item.guid.isPermaLink=
* securerandom
SecureRandom.uuid
New method to generate a v4 random UUID.
* set
Set#classify
Set#collect!
Set#delete_if
Set#divide
Set#reject!
SortedSet#delete_if
Return an enumerator if no block is given.
* stringio
* StringIO#ungetbyte
Added as an alias to #ungetc.
=== Compatibility issues (excluding feature bug fixes)
* builtin classes
* Enumerator#rewind
See above.
* open-uri
* URI::InvalidURIError is converted to OpenURI::HTTPError if an
invalid HTTP URI is given.
