2021-08-21Organize the include of header filesdearblue
- `#include <math.h>` is done in `mruby.h`. Eliminate the need to worry about the `MRB_NO_FLOAT` macro. - Include mruby header files before standard header files. If the standard header file is already placed before `mruby.h`, the standard header file added in the future tends to be placed before `mruby.h`. This change should some reduce the chances of macros that must be defined becoming undefined in C++ or including problematic header files in a particular mruby build configuration.

2021-01-26Revert "Minimize the changes in #5277"Yukihiro "Matz" Matsumoto
This reverts commit dc51d89ac22acc60b9bfeed87115863565b74085.
2021-01-22Minimize the changes in #5277Yukihiro "Matz" Matsumoto
Instead of including `mruby/presym.h` everywhere, we provided the fallback `mruby/presym.inc` under `include/mruby` directory, and specify `-I<build-dir>/include` before `-I<top-dir>/include` in `presym.rake`. So even when someone drops `-I<build-dir>/include` in compiler options, it just compiles without failure.
2021-01-11Avoid including `presym.inc` in existing header filesKOBAYASHI Shuji
Addressed an issue where existing programs linking `libmruby.a` could only be built by adding `<build-dir>/include` to compiler's include path.
2020-11-21Rename `MRB_{ENABLE,DISABLE}_` to `MRB_{USE,NO}_`; close #5163KOBAYASHI Shuji

2020-10-12Use `mrb_integer()` instead of `mrb_int()`.Yukihiro "Matz" Matsumoto
`mrb_int()` includes implicit integer conversion, where `mrb_integer()` does not. In this case, we know `obj` is an integer before hand.
2020-10-12Use `mrb_int_value()` instead of `mrb_fixnum_value()`.Yukihiro "Matz" Matsumoto
Where fixnum overflow can happen.
2020-10-12Reorganize `Integer` system.Yukihiro "Matz" Matsumoto
- 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()`
2020-10-12Rename `MRB_TT_FIXNUM` to `MRB_TT_INTEGER`.Yukihiro "Matz" Matsumoto
We still have `#define MRB_TT_FIXNUM MRB_TT_INTEGER` for compatibility.
2020-10-12Rename float configuration option names.Yukihiro "Matz" Matsumoto
- `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.
2020-10-12Change out-of-range condition of `time_t` conversion.Yukihiro "Matz" Matsumoto
2020-10-12Avoid out-of-range error for negative time on `MRB_TIME_T_UINT`.Yukihiro "Matz" Matsumoto
On platforms where `time_t` is unsigned, negative time can be a result of integer casting. Out-of-range error is too strict for those cases. This fix does not address wrong time value in `MRB_WORD_BOXING`. It will be addressed later (by introducing "big" integers).
2020-10-12Use functions that take symbols to reduce string litrals in C.Yukihiro "Matz" Matsumoto
2020-06-20Add `mrb_get_arg1()` that retrieves single (and only) argument.Yukihiro "Matz" Matsumoto
`mrb_get_arg1()` raises `ArgumentError` if the method does not receive one argument. And replaces all `mrb_get_args(mrb, "o", &arg)` by the new function.
