Add paragraph mode to String#each_line in mrblib
2019-06-29Replace `String#[]=` method by C implementsdearblue
The purpose is to eliminate string objects that are temporarily created during processing.

2019-06-23Optimize String#each_lineRyan Lopopolo
2019-06-22Speed up base case by 2xRyan Lopopolo
Make non-paragraph mode twice as fast. Performance is within a factor of 2 of the original implementation.
2019-06-22Add paragraph mode to String#each_line in mrblibRyan Lopopolo
mruby/mruby#4511 demonstrated an infinite loop in `String#each_line` when given an empty string separator. In MRI, an empty separator places String#each_line in paragraph mode, where the String is separated on successive runs of newlines. In paragraph mode, the String `"abc\n\n\ndef\nxyz"` is split into `["abc\n\n\n", "def\nxyz"]`. This commit makes the String#each_line implementation as close to ruby/spec compliant as possible given the limitations of mruby core. With this patch, the following specs fail for `String#each_line`: - uses `$/` as the separator when none is given (can be fixed by aliasing and redefining the method to use $/ as the default value of separator in mruby-io) - when no block is given returned Enumerator size should return nil (`Enumerator#size` is not supported on mruby) - tries to convert the separator to a string using to_str (`String#to_str` is not implemented on mruby) This patch has similar memory consumption compared to the prior implementation and is takes 4x the time the prior implementation takes to execute: ```console /usr/bin/time -l ./bin/mruby -e '("aaa\n\nbbbbb\n\n\n\n\ncccc" * 100000).each_line("\n") { }'; ```
2019-05-15Add Enumerator support to `String#each_byte`.Yukihiro "Matz" Matsumoto
`String#each_byte` is not defined in ISO Ruby but it is implemented in the core mruby because it's useful.
2019-05-15Remove `String#=~` and `String#match` that requires `Regexp`.Yukihiro "Matz" Matsumoto
2019-04-27Remove duplicated `String#each_char`KOBAYASHI Shuji
2019-04-21Commented out `String#scan` because it is not implemented yetKOBAYASHI Shuji
2019-04-19Add type check (conversion) in `String#[]=`KOBAYASHI Shuji
Before this patch: 'a'[0] = 1 #=> 1 'a'[:a] = '1' #=> ArgumentError 'a'[:a, 0] = '1' #=> ArgumentError 'a'[0, :a] = '1' #=> ArgumentError 'a'[0, 1] = 1 #=> 1 After this patch / Ruby: 'a'[0] = 1 #=> TypeError 'a'[:a] = '1' #=> TypeError 'a'[:a, 0] = '1' #=> TypeError 'a'[0, :a] = '1' #=> TypeError 'a'[0, 1] = 1 #=> TypeError

2018-11-19Remove implicit conversion using `to_str` method; fix #3854Yukihiro "Matz" Matsumoto
We have added internal convenience method `__to_str` which does string type check. The issue #3854 was fixed but fundamental flaw of lack of stack depth check along with fibers still remains. Use `MRB_GC_FIXED_ARENA` for workaround.
2018-08-07Fixed the corner case bug in `String#{gsub!,sub!}`.Yukihiro "Matz" Matsumoto
`"a".sub!("a", "a")` should not return `nil`.

`FrozenError` is a subclass of `RuntimeError` which used to be raised. [Ruby2.5]
