They return the checking argument without modification, so the values
are already there. Maybe we should change the return type to `void` but
keep them unchanged for compatibility.
- Removed the `ARGV` macro.
The current path doesn't go into the mruby VM and there's also no need to separate variables.
- Use common functions to check object types.
- Use `mrb_ensure_string_type()` to check the string instead of `mrb_to_str()`.
This is for consistency with array and hash.
- Use `mrb_ensure_array_type()` to check the array instead of `to_ary()`.
- Use `mrb_ensure_hash_type()` to check the hash instead of `to_hash()`.
- Add and use `ensure_class_type()` to check class and module.
- Changed the argument index type from `mrb_int` to `int`.
Even if it is `int16_t`, it is enough.
`mrb_int` is overkill, especially if `MRB_32BIT` and `MRB_INT64` are defined.
* use predefined `mrb_ro_data_p()` for user-mode Linux and macOS
* define `MRB_LINK_TIME_RO_DATA_P` if predefined one is used
* configure macro `MRB_USE_LINK_TIME_RO_DATA_P` is no longer used
* contributions for new platforms are welcome
This now works with the `+` modifier that can be added after each specifier.
- `nil` is bypassed.
- The `s` and `z` specifiers are received in C as a `const char *`, so adding a `+` modifier will raise an exception.
- The `a` specifier is received in C as `const mrb_value *`, so adding a `+` modifier will raise an exception.
- The `|`, `*`, `&`, `?` and `:` specifiers with `+` modifier raises an exception.
If `!`/`+` exceeds one for each specifier, an exception will occur in the subsequent processing.
This is the same behavior as before.
The previously used `given` variable will be merged into the `pickarg` pointer variable, which points to the argument currently being processed for each loop.
- `#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.
Embedding reduce memory consumption, sacrificing precision. It clips least
significant 2 bits from `mrb_float`, so if you need to keep float precision,
define `MRB_USE_FLOAT_FULL_PRECISION`.
`MRB_WORD_BOXING` and `MRB_INT64`:
`mrb_float` (`double`) is embedded in `mrb_value` clipped last 2 bits.
`MRB_WORD_BOXING` and `MRB_INT64` and `MRB_USE_FLOAT_FULL_PRECISION`:
`mrb_float` is allocated in the heaps wrapped by `struct RFloat`.
`MRB_WORD_BOXING` and `MRB_INT32` and `MRB_USE_FLOAT32`:
`mrb_float` (`float`) is embedded in `mrb_value` clipped last 2 bits.
In addition, to reserve bit space in the `mrb_value`, maximum inline
symbol length become 4 (instead of 5) in the configuration.
`MRB_WORD_BOXING` and `MRB_INT32`:
Assume `MRB_USE_FLOAT_FULL_PRECISION` and allocate Float values in heap.
