What happened on the mruby front in February 2013?
The big topic in February 2013 was the gemification of many mruby core features. In detail the Regular Expression Engine, the Math module, the Time class and Struct were extracted from the mruby core and transformed into independent GEMs. Math, Time and Struct will be maintained inside of the mruby repository. Due to the reason that there are several Regexp implementations (see Pluggable RegExp) these GEMs are maintained in their own repository.
Serg Podtynnyi built a cross compilation toolchain configuration for Android. It is using the Android NDK to build a mruby executable which can be executed under Android.
Based on kyab‘s work on cross compiling to our first Arduino compatible device (ChipKitMax32) I created an example build configuration file inside of the mruby source.
Akira Yumiyama added several new assert methods like:
assert_trueassert_nilassert_equalassert_includesassert_instance_ofassert_kind_ofassert_raisesIt is now also possible the pass the verbose flag to minirake which will then output a very detailed test result of every test case with ISO code (if existing). Skip a test is possible too now.
String got a couple of new methods like #sub, #sub!, #gsub and #gsub!. At the same time Module got a new method called #remove_const.
Here a list with all commits during this month.

Regexp: %r notation bug fix. close #85.
Put mruby-time mgem into the repository.
Remove needless files
Pluggable Time class
Remove needless file

Add androideabi toolchain rake task (Build mruby with Android NDK)
Rake respects verbose flag also for test and clean target
rename assert_raises to assert_raise
remove assert_instance_of and assert_kind_of which might hinder duck typing
rename assert_includes to assert_include
Add skip method for test
add assert_{includes,instance_of,kind_of,raises} methods.
declare local variable at the start of a block in generated gem_test.c
update String#gsub test
add assert_{true,nil,equal} methods.
add mrbtest verbose mode (‘-v’ option)
Add more tests for `begin` and `rescue`.
Generate mrbtest.a file for sparete from driver.o
adopt String#gsub to fixed split behavior
String#split should honor limit arg

fix error output for Module#remove_const
add Module#remove_const
Added String#sub/sub! and String#gsub/gsub!
Adjust space
Fix arena size check.
Do not generate test_args_hash variable if it is not used
Remove freeze leftovers
Ignore *.d, *.o, and /lib
Add document for array_copy
Modify stack position of NODE_DEF and NODE_SDEF.
Increase TEST_INFINITE_RECURSION_MAX value from 100000 to 1000000 because modification of handling of `NODE_RETURN` reduces stack size.
Return nil if argument of NODE_RETURN and NODE_NEXT is not specified.
Clean code up.
mrb_funcall_with_block: adj. ci & sp after error
Simplify mrb_range_beg_len(). Don’t use OTHER macro.

Reduce sprintf() calls. Remove mrb_int_to_str() and MRB_INT_FORMAT.
Support to build on pwd != mruby source root
Fix errors caused by stdio.h dependent code.
Cleanup shift operations.
Fix an underlying bug. flodivmod() will be crashed in case ((y == 0) && ((divp == NULL) || (modp == NULL))).
Add a comment.
Remove a comment at an unsuitable place.
Cosmetic changes. Just added empty lines.
Fix mrb_fix2str() to enable handling some negative values correctly. This fix is based on @cremno’s hack. It will fix #869.

“for i in (1..12/5); p i ; end” should not print “3″
Don’t overwrite ciidx if it is already set.
Ignore empty gem
Change task rule based on build_dir so main rules don’t clobber gem rules.
