(`mrb_rescue_exceptions` is mruby implementation of `rb_rescue2`.)
Closes #2844, closes #2837.
|
|
Note: arguments of mrb_no_method_error() has changed. You need to replace
3rd and 4th argument (say n, argv) to mrb_ary_new_from_values(mrb, n, argv).

Dr Markus Kuhn published in 1999 an article [1] explaining in details
why we shouldn't use the ASCII grave accent (0x60) as a left quotation.
Backticks have been used most notably to produce nice-looking LaTeX
documents but it doesn't seem to be an issue on modern platforms and
for the oldest ones, there are workarounds as mentioned by Dr Kuhn.

Reduces the file size (by up to 2 KB with VS2015 RC, /O2, /MD) and
removes the requirement of including <ctype.h> before their usage.
Multiple macro argument evaluation and lack of type-checking is still an
issue.

Related to #2760.

mrb_str_new() takes size_t, so should mrb_exc_new().
|
|
It isn't used anymore since the #2791 merge. It's also unlikely to be
needed again as it wasn't before (its usage was unnecessary).
|
|
remove mrb_define_method_vm() function
|
|
It isn't needed as it's very similar to mrb_define_method_raw() and also
there's only one place where mrb_proc_ptr() actually has to be called.
Inspired by @furunkel's method cache patch (#2764).

remove unnecessary <inttypes.h> inclusion
|
|
The format specifier macros were needed to portably print a mrb_int,
because mrb_raisef() originally called vsnprintf(). It doesn't anymore
since 18b2683b97ae54d4f2f15c19076f33aa29eaf2b7 and the mrb_int format
specifier macros are already gone.
|
|
Apparently the C compiler of Visual Studio 2015 CTP6 finally implements
inline as inline and not only as _inline and __inline.
|
|
|
|
The new implementation is backwards incompatible, but I couldn't find
any usage outside mruby and I also couldn't think of a different and
good name.
All ISO C99 printf conversion specifiers for floating point numbers and
an optional precision are supported.
It is largely based on code from the MIT licensed musl libc
(http://www.musl-libc.org/) and its floating point printing is exact
(unlike the current code behind Float#to_s).

`mruby -b` now accepts both big/little endian mrb (compiled binary) files.
`mrbc` generates mrb files in big endian for .mrb files and in native endian
for C files (with -B option specified) by default. If you are cross compiling,
you need to specify target endian by -e/-E options if it is different from
host endian.

resize; fix #2682
|

Visual Studio versions older than 2013 lack C99's isblank().
Since only ASCII characters are passed to it, implement it
directly without calling the locale-specific isblank().

Add padding bytes before iseq block that may be used as mrb_code[].
Note that dumped mrb format has changed.

b72e94f used _etext and _edata to distinguish C string literals from heap allocated strings,
but using _edata, global char arrays may be considered as string literals. to avoid the issue,
we have to use __init_array_start, which might be less portable. you can still use _edata, by
using MRB_NO_INIT_ARRAY_START.
|
|
on platforms with _etext and _edata, mruby can distinguish string literals so that it avoids memory allocation to copy them.
for example, on my Linux box (x86 32bit), memory consumed by mrbtest decreased from 8,168,203 to 8,078,848 (reduced 88KB).
|
|
instead of adding sym->name hash table, linear symbol table is added, and reduced name->sym hash table size.
|
|
It is declared in mruby.h.

`mrb_value` to make it consistent with mrb_const_defined; ref #2593

if you see compiler errors due to this commit, you'd better to use array-modifying
functions, e.g. mrb_ary_set() or mrb_ary_push(), otherwise you might see nasty
GC bugs in the future. if you are sure what you are doing, replace `RARRAY_PTR(ary)`
by `mrb_ary_ptr(ary)->ptr`. but be warned.
