Internal functions can only be called from within the library.
Functions listed in `mruby/internal.h` can be called from:
* core (src/*.c)
* gems (mrbgems/**/*.c)
But not from the application linked with `libmruby`.
[Breaking changes]
Developers must use following APIs for accessing attributes of RRange
because RRange structure depends on boxing setting.
- mrb_range_beg
- mrb_range_end
- mrb_range_excl_p
The new API is:
int mrb_range_beg_len(mrb, range, &beg, &len, len, trunc)
The new argument `trunc` is a boolean value that specifies
whether the function truncates the range. The new return value
is an integer instead of a boolean, that is:
0: not a range
1: range with proper edges
2: out of range
To get the old behavior, you have to rewrite:
mrb_range_beg_len(mrb, range, &beg, &len, len)
to:
mrn_range_beg_len(mrb, range, &beg, &len, len, TRUE) == 1
[Breaking Change]
It doesn't matter to me if one is using FALSE/TRUE instead of 1/0
but I prefer a type (alias) which emphasizes boolean vars to int.
I changed 1/0 to FALSE/TRUE anyway.
The following is legal code in both C and C++:
struct foo {
struct bar { int a } x;
int y;
};
...however in C++ it defines a type called "foo::bar" instead of "bar".
Just avoid this construct altogether
