* Enumerator.new: raise unless block given卜部昌平2020-12-221-10/+4
| | | | | Has been deprecated since c73b6bd7ebd01133538c645566944132dbde4d13. [Feature #17116] [ruby-dev:50945]
* test/ruby/test_enumerator.rb: check the deprecation warningYusuke Endoh2020-09-251-1/+9
| | | | | | | | | by explicitly setting `Warning[:deprecated] = true`. I removed "capture_io" at 79063d8cbfb7ce4740774289252a2a20dc9a5dc1, but it printed the warning when `RUBYOPT=-w`. This change makes the warnings enabled explicitly, capture and check the warning.
* test/ruby/test_enumerator.rb: remove capture_io that is no longer neededYusuke Endoh2020-09-251-3/+1
| | | | | | The deprecation warning was disabled, and the code to check the warning was removed at 996af2ce086249e904b2ce95ab2fcd1de7d757be, thus capture_io is no longer needed.
* Disable deprecation warning by the default [Feature #16345]Nobuyoshi Nakada2020-09-251-1/+0
| | | | And `-w` option turns it on.
* Make Enumerator::Chain#each treat lambdas as lambdaJeremy Evans2019-12-031-0/+16
| | | | | | | | Previously, lambdas were converted to procs because of how rb_block_call works. Switch to rb_funcall_with_block, which handles procs as procs and lambdas as lambdas. Fixes [Bug #15613]
* Add rb_enumeratorize_with_size_kw and related macrosJeremy Evans2019-09-301-0/+8
| | | | | | | | | | Currently, there is not a way to create a sized enumerator in C with a different set of arguments than provided by Ruby, and correctly handle keyword arguments. This function allows that. The need for this is fairly uncommon, but it occurs at least in Enumerator.produce, which takes arugments from Ruby but calls rb_enumeratorize_with_size with a different set of arguments.

| | | | | | | | | | | | | | | | They return an Enumerator::Chain object which is a subclass of Enumerator, which represents a chain of enumerables that works as a single enumerator. ```ruby e = (1..3).chain([4, 5]) e.to_a #=> [1, 2, 3, 4, 5] e = (1..3).each + [4, 5] e.to_a #=> [1, 2, 3, 4, 5] ``` git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65949 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* Set the size of a new enumerator created by Enumerator#each with arguments ↵knu2018-10-221-2/+5
| | | | | | | | | | | to nil When each() takes arguments, it is never safe to assume that the iteration would repeat the same number of times as with each() without any argument. Actually, there is no way to get the exact number, so the size should be set to nil to denote that. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65302 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* enumerator.c: Introduce Enumerator::ArithmeticSequencemrkn2018-08-061-1/+1
| | | | | | | | | | | | | | | | | | | This commit introduces new core class Enumerator::ArithmeticSequence. Enumerator::ArithmeticSequence is a subclass of Enumerator, and represents a number generator of an arithmetic sequence. After this commit, Numeric#step and Range#step without blocks returned an ArithmeticSequence object instead of an Enumerator. This class introduces the following incompatibilities: - You can create a zero-step ArithmeticSequence, and its size is not ArgumentError, but Infinity. - You can create a negative-step ArithmeticSequence from a range.

* Add FrozenError as a subclass of RuntimeErrorshyouhei2017-12-121-2/+2
| | | | | | | | | | | | | | FrozenError will be used instead of RuntimeError for exceptions raised when there is an attempt to modify a frozen object. The reason for this change is to differentiate exceptions related to frozen objects from generic exceptions such as those generated by Kernel#raise without an exception class.
