Yukihiro "Matz" Matsumoto 5134031e18 Use mrb_int_value() instead of mrb_fixnum_value(). 
Where fixnum overflow can happen.
 2020-10-12 18:20:05 +09:00
Yukihiro "Matz" Matsumoto 2b188ed8a1 Reorganize Integer system. 
- Integrate `Fixnum` and `Integer`
- Remove `Integral`
- `int / int -> int`
- Replace `mrb_fixnum()` to `mrb_int()`
- Replace `mrb_fixnum_value()` to `mrb_int_value()`.
- Use `mrb_integer_p()` instead of `mrb_fixnum_p()`

Yukihiro "Matz" Matsumoto 12d31c33af "backport" CRuby r46656; #2500 
Based on cremno/mruby@d446192
 2020-10-12 16:21:49 +09:00
Yukihiro "Matz" Matsumoto 55163a8a0a Rename MRB_TT_FIXNUM to MRB_TT_INTEGER. 
We still have `#define MRB_TT_FIXNUM MRB_TT_INTEGER` for compatibility.

Also remove some unnecessary code.

cremno b44326b561 Add tests for CRuby bug #9982 
https://bugs.ruby-lang.org/issues/9982
 2020-10-12 16:21:45 +09:00
Yukihiro "Matz" Matsumoto 8a87549315 Rename float configuration option names. 
- `MRB_WITHOUT_FLOAT` => `MRB_NO_FLOAT`
- `MRB_USE_FLOAT` => `MRB_USE_FLOAT32`

The former is to use `USE_XXX` naming convention. The latter is to make
sure `float` is 32bit float and not floating point number in general.
 2020-10-12 16:21:40 +09:00
Yukihiro "Matz" Matsumoto 00f5ddc9ae Use mrb_funcall_id() extensively. 
Except for support files e.g. `mruby-test/driver.c`, which are not
target of symbol collection via `rake gensym`.

Yukihiro "Matz" Matsumoto d40b922c98 Fix potential buffer overflow in sprintf.c. 2020-06-20 18:56:33 +09:00
Yukihiro "Matz" Matsumoto a476c83caf Move fmt_setup until absolutely necessary. 2020-05-27 14:09:36 +09:00
Yukihiro "Matz" Matsumoto 15c63688e3 Integer format can be bigger than 32 on 64bit platforms. 
We made it `64` which should be big enough:
- Format modifier: 4 characters max
- Maximum width: 19 digits max
- Period between width and precision: 1 character
- Maximum precision: 19 digits max
- Format specifier: 1 character
- NUL terminator: 1 byte
- Total: 45 < 64

dearblue 2ceab2d270 Supports some specifier flags with mrb_float_to_str() 
Changed to understand `#`, `0`, `-`, ` ` and `+`.

dearblue 67606170e3 Add configuration guard for MRB_DISABLE_STDIO 
ref #4576 and ref #4947

* Need MRBAPI functions without `MRB_DISABLE_STDIO`:
  * mrbgems/mruby-bin-debugger
  * mrbgems/mruby-bin-mirb
  * mrbgems/mruby-bin-mrbc
  * mrbgems/mruby-bin-mruby
  * mrbgems/mruby-bin-strip

  * mrbgems/mruby-print
* Need `snprintf()` in `stdio.h`:
  * mrbgems/mruby-pack
  * mrbgems/mruby-sprintf
 2020-03-08 21:57:17 +09:00
dearblue cc1db2d117 Remove unnecessary 'stdio.h'; ref #4947 
'stdio.h' is included in 'mruby.h' ('mrbconf.h').

However, keep 'stdio.h' used by mruby-test.

 2019-09-26 09:48:01 +09:00
Yukihiro "Matz" Matsumoto 0d661bcca6 Merge pull request #4731 from dearblue/consistent-type

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.

BTW, I accidentally changed `tasks/toolchains/visualcpp.rake` at #4613,
so I put it back.

Yukihiro "Matz" Matsumoto 625976d793 Fix integer overflow issue; fix #4108 
I misunderstood the return value from `snprintf()`, which is NOT number
of characters written in buffer, but the number of character the buffer
has to have to write the complete output.

Tomasz Dąbrowski 17c249780f fix String#% %d test with MRB_INT16 set 2017-08-25 14:36:05 +02:00
Yukihiro "Matz" Matsumoto f1767fd079 Separate mrb_str_buf_new and mrb_str_new_capa. 
`mrb_str_buf_new` is an old function that ensures capacity size of
`MRB_STR_BUF_MIN_SIZE` minimum. Usually one need to use
`mrb_str_new_capa` instead.

Yukihiro "Matz" Matsumoto b68e7a605c Negation was not a good way to handle negative integers; fix #3729 
There's a number that negation does not work (-2147483648 in 32bit
environment).

Yukihiro "Matz" Matsumoto b643a1a8bc In Ruby, sprintf specifier %u should behave as %d; fix #3730 
Since there's no unsigned integer in Ruby. Binary, octal and
hexadecimal negative numbers can be represented by using 2's
compliment. But decimal (not being power of 2) cannot be use
that kind of format.
