shuujii/use-mrb_int-instead-of-to_int-in-mruby-numeric-ext
Use `mrb_int()` instead of `to_int()` in `mruby-numeric-ext`
|
|
Add constants for floating point number
|
|
|
|
|
|
- `size_t` is more commonly used.
- `len` argument of `mrb_str_new()` is `size_t`.
NOTE:
The test for `%l` is temporarily disabled because adding a new type to
`mrbgems/mruby-test/vformat.c` causes an error (memory error?) on Visual
Studio 2017 in AppVeyor.
|
|
Fix `mrb_vformat("%f")` with `MRB_USE_FLOAT`
|
|
It potentially not work when `mrb_float` is `float` because `float` variable
in variable length arguments is promoted to `double`.
Also I fixed build with `MRB_WITHOUT_FLOAT`.
|
|
Warnings:
- If `MRB_TIME_T_UINT` is defined, the compiler issues a warning with an
integer comparison of different signs.
- It is mentioned that the `usec` variable passed to the
`mrb_to_time_t()` function may not be initialized
|
|
It potentially breaks, for example, in the case of `mrb_int` is 64-bit
and more smaller type is passed by `%d`. In fact, the problem could
become apparent when I used `%d` to `backtrace_location::lineno` in
`src/backtrace.c:mrb_unpack_backtrace()` on AppVeyor.
Therefore, change `%d` for `int` (not `mrb_int`) so that it can be
used mostly without casting.

Format sequence syntax:
%[modifier]specifier
Modifiers:
----------+------------------------------------------------------------
Modifier | Meaning
----------+------------------------------------------------------------
! | Convert to string by corresponding `inspect` instead of
| corresponding `to_s`.
----------+------------------------------------------------------------
Specifiers:
----------+----------------+--------------------------------------------
Specifier | Argument Type | Note
----------+----------------+--------------------------------------------
c | char |
d,i | mrb_int |
f | mrb_float |
l | char*, mrb_int | Arguments are string and length.
n | mrb_sym |
s | char* | Argument is NUL terminated string.
t | mrb_value | Convert to type (class) of object.
v,S | mrb_value |
C | struct RClass* |
T | mrb_value | Convert to real type (class) of object.
Y | mrb_value | Same as `!v` if argument is `true`, `false`
| | or `nil`, otherwise same as `T`.
% | - | Convert to percent sign itself (no argument
| | taken).
----------+----------------+--------------------------------------------
This change will increase the binary size, but replacing all format strings
with new specifiers/modifiers will decrease the size because it reduces
inline expansion of `mrb_obj_value()`, etc. at the caller.

Use own implementation to calculate UTC offset on Visual Studio 2015 or
earlier or MinGW because `strftime("%z")` on these environments does not
conform C99.

Refine message to `skip` in nested `assert`
|
|
- I think "Info" is used only to `skip`, so change to "Skip".
- Changed the default value of `assert` and specify the argument explicitly
at the caller of `assert` because it is unnatural "Assertion failed" is
output even though the assertion doesn't fail.
== Example:
def assert_foo(exp, act)
assert do
assert_equal exp[0], act[0]
assert_equal exp[1], act[1]
end
end
def assert_bar(exp, act)
assert do
skip
end
end
def assert_baz(exp, act)
assert do
assert_equal exp, act
assert_bar exp, act
end
end
assert 'test#skip_in_nested_assert' do
assert_baz 1, 1
end
=== Before this patch:
?..
Info: test#skip_in_nested_assert (core)

Info: Assertion failed (core)
- Assertion[1-2]
Skip: Assertion failed (core)

strftime() on Windows returns locale encoding time zone for "%z" even
if MSDN says "%z" is "The offset from UTC in ISO 8601 format; no
characters if time zone is unknown" in MSDN:
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/strftime-wcsftime-strftime-l-wcsftime-l?view=vs-2019
So we need to convert encoding of string from strftime().

Remove `Enumerator::Chain#initialize_copy`
|
|
|
|
I think `Enumerator::Chain#initialize_copy` is unnecessary because CRuby
doesn't clone elements.

Fix the lack of precision for `Time`; ref d74355061
|
|
- `Time.local` and `Time.utc` are able to use with `MRB_INT16 + MRB_WITHOUT_FLOAT`.
- `time_t` is converted directly from the Ruby object.
- `time + sec` and` time - sec` are not affected by the precision of `mrb_float`.
Similarly, calculations are possible with `MRB_INT16 + MRB_WITHOUT_FLOAT`.
|
|
|
|
Fix mruby-time with `MRB_WITHOUT_FLOAT`; ref d74355061
|
|
Also fix the misfeature introduced in 23783a4, that ignores newlines
between method chains.

Drop dependency from `mruby-array-ext` to `mruby-enum-ext`

shuujii/move-NilClass-to_h-to-mruby-object-ext-from-mruby-enum-ext
Move `NilClass#to_h` to `mruby-object-ext` from `mruby-enum-ext`
|
|
|
|
- No guarantees about the order in which the permutations/combinations
are yielded.
- Drop dependency on `Enumerator`.

When the size of Xorshift128 seed (`sizeof(uint32)*4`) is bigger than
ISTRUCT_DATA_SIZE, `Random` uses Xorshift96 instead.

Currently, `Integral#chr` in mruby changes behavior by `MRB_UTF8_STRING`
setting.
before this patch:
$ bin/mruby -e 'p 171.chr' #=> "\xab" (`MRB_UTF8_STRING` is disabled)
$ bin/mruby -e 'p 171.chr' #=> "«" (`MRB_UTF8_STRING` is enabled)
This behavior is incompatible with Ruby, and a little inconvenient because
it can't be interpreted as ASCII-8BIT with `MRB_UTF8_STRING`, I think.
So add encoding argument according to Ruby.
after this patch:
$ bin/mruby -e 'p 171.chr' #=> "\xab"
$ bin/mruby -e 'p 171.chr("ASCII-8BIT")' #=> "\xab"
$ bin/mruby -e 'p 171.chr("UTF-8")' #=> "«"
Allow only `String` for encoding because mruby doesn't have `Encoding`
class, and `"ASCII-8BIT"` (`"BINARY"`) and `"UTF-8"` (only with
`MRB_UTF8_STRING`) are valid value (default is `"ASCII-8BIT"`).

shuujii/integrate-Integral-chr-Fixnum-chr-to-mruby-string-ext
Integrate `Integral#chr` (`Fixnum#chr`) to `mruby-string-ext`
|
|
As a side effect, `mrb_time_at()` now takes `mrb_int` instead of
`double` as time arguments.
|
|
|
|
The Complex class needs `mrb_float` so that it does not work with
`MRB_WITHOUT_FLOAT` anyway.
|
|
Now `rand` can be used with `MRB_WITHOUT_FLOAT`; ref #4576
|
|
Because they're defined in both `mruby-string-ext` and `mruby-numeric-ext`
(they seem more natural to define in N, but `mruby-string-ext` depends on
`Integral#chr`).

Revert #4300
|
|
Originally, it was not necessary to change. I made mistake.
|
|
Before this patch:
$ bin/mruby -e 'p (2...4.0).min' #=> TypeError
After this patch (same as CRuby and without `mruby-range-ext`):
$ bin/mruby -e 'p (2...4.0).min' #=> 2
