[August 2012] mruby news

I tried the other day to setup a mailing-list for mruby. Due to the reason that there isn’t any platform yet for discussions. While doing this I messed up a little bit my platform. So now everything is up and running again and hopefully we soon have some kind of mailing-list which we can use for further discussions.

Nevertheless back to normal…

What happened last month on the mruby front?

BEGIN/END

BEGIN/END was removed from the mruby syntax.

mirb

Handling of exit and quit was optimized inside of the mirb tool. Also the internal state was fixed in case of a syntax error.

Xcode Integration

Paolo Bosetti was working on improving the Xcode integration (i.e. for Mac OS X 10.8 Mountain Lion).

NaN Boxing

MRB_NAN_BOXING and MRB_ENDIAN_BIG was introduced for customising the mruby interpreter even more. The NaN Boxing is at the moment conflicting with the FLOAT implementation. Due to that MRB_USE_FLOAT and MRB_NAN_BOXING can’t be used at the same time.

mruby tool with stdin

mruby can now read from the stdin if no argument is given. This gives more possibilities to connect mruby with other unix command line tools.

puts optimization

`puts` should print “n” only when the argument does not end with “n”.

Exception Handling

Masamitsu MURASE was working on the exception handling and added additional tests.

Add GC.disable and GC.enable to control the Garbage Collector.

Math::TOLERANCE

Implement Math::TOLERANCE in C and modify precision.

Improvement of Float

Float was fixed so that there is now enough precision to round and represent a Fixnum.
