Yukihiro "Matz" Matsumoto 8627157298 Fix IO#readchar to return broken UTF-8 rather than EOF error. 
The behavior is different from CRuby, but we believe this is a right
behavior for mruby, which only supports either ASCII or UTF-8
exclusively; fix #4983, ref #4982

```
$ printf '\xe3\x81' | ruby -e 'p STDIN.readchar'
"\xE3\x81"
```

```
$ printf '\xe3\x81' | mruby -e 'p STDIN.readchar'
"\xE3"
```

Include time.h for ios
 2020-02-05 23:11:45 +09:00
dearblue 4c6d524c47 Implement IO#pread and IO#pwrite 
It is available by default in environments where `__unix__` is defined.
Other environments are enabled by defining `MRB_WITH_IO_PREAD_PWRITE`
(requires an implementation of `pread()` and `pwrite()` functions).

In any case, you can disable it by defining
`MRB_WITHOUT_IO_PREAD_PWRITE`.

KOBAYASHI Shuji feaf80d899 Use type predicate macros instead of mrb_type if possible 
For efficiency with `MRB_WORD_BOXING` (implement type predicate macros for
all `enum mrb_vtype`).
 2019-09-26 22:23:27 +09:00
Yukihiro "Matz" Matsumoto 6f1c08f7d8 Replace String#byteslice by custom IO._bufread. 
`byteslice` creates 2 string objects. `_bufread` creates one, and
modifies the original buffer string, that is more efficient.

Yukihiro "Matz" Matsumoto 231a1d68b0 Remove $/ from mruby implementation. 
1. `$/` and other Perl-ish global variables are not defined in ISO.
2. The current Ruby policy do not encourage those variables.
3. Those variables has global effect and can cause troubles.

KOBAYASHI Shuji 334afb167c Use new specifiers/modifiers of mrb_vfromat() 
The binary sizes (gems are only `mruby-bin-mruby`) are reduced slightly in
my environment than before the introduction of new specifiers/modifiers
(5116789a) with this change.
