Language Spec.
- Class#allocate - basicNew
- class Foo::Bar<Baz .. end, module Boo::Bar .. end
- raise exception by `` error
- a +1 to be a+1, not a(+1).
- clarify evaluation order of operator argument (=~, .., ...)
- :symbol => value hash in the form of {symbol: value, ...} ??
* operator !! for rescue. ???
* objectify characters
* ../... outside condition invokes operator method too.
* ... inside condition turns off just before right condition.???
* package or access control for global variables??
* named arguments like foo(nation:="german") or foo(nation: "german").
* method to retrieve argument information (needs new C API)
* multiple return values, yield values. maybe incompatible ???
* cascading method invocation ???
* def Class#method .. end ??
* def Foo::Bar::baz() .. end ??
* I18N (or M17N) script/string/regexp
* discourage use of symbol variables (e.g. $/, etc.) in manual
* discourage use of Perlish features by giving warnings.
* non confusing in-block local variable (is it possible?)
+ remove scope by block
+ variables appears within block may have independent values.
* Regexp: make /o thread safe.
* decide whether begin with rescue or ensure make do..while loop.
* unify == and eql? again
* to_i returns nil if str contains no digit.
* jar like combined library package. -> RubyGems?
* method combination, e.g. before, after, around, etc.
* .. or something like defadvice in Emacs.
* property - for methods, or for objects in general.
* "in" modifier, to annotate, or to encourage assertion.
* selector namespace - something like generic-flet in CLOS, to help RubyBehavior
* private instance variable (as in Python?) @_foo in class Foo => @_Foo_foo
* warn/error "bare word" method, like "foo", you should type "foo()"
Hacking Interpreter
- generational GC
* non-blocking open (e.g. for named pipe) for thread
* avoid blocking with gethostbyname/gethostbyaddr (use fork ???)
* objectify interpreters ???
* remove rb_eval() recursions
* syntax tree -> bytecode ???
* scrambled script, or script filter
* setuid ruby
* performance tune for in-block (dynamic) local variables.
* give warnings to assign magic variables.
* export rb_io_{addstr,printf,puts,print}
* autoload should work with threads [ruby-talk:4589]
* remove stdio dependency from IOs.
* warn for inconsistent local variable usage (lv m and method m at the same time).
* MicroRuby
* Built-in Interactive Ruby.
* Parser API
* trap every method invocation, which can be enabled by e.g. trap_call :method.
* eval.c (block_pass): should not downgrade safe level. * ext/dbm/extconf.rb: allow specifying dbm-type explicitly. * ext/dbm/extconf.rb: avoid gdbm if possible, because it leaks memory, whereas gdbm.so doesn't. potential incompatibility. * string.c (rb_str_insert): new method. * parse.y (yylex): lex_state after RESCUE_MOD should be EXPR_BEG. * array.c (rb_ary_insert): new method. * array.c (rb_ary_update): new utility function. * io.c (set_outfile): should check if closed before assignment. * eval.c (rb_eval): should preserve value of ruby_errinfo. * eval.c (rb_thread_schedule): infinite sleep should not cause dead lock. * array.c (rb_ary_flatten_bang): proper recursive detection. * eval.c (yield_under): need not to prohibit at safe level 4. * pack.c (pack_pack): p/P packs nil into NULL. * pack.c (pack_unpack): p/P unpacks NULL into nil. * pack.c (pack_pack): size check for P template. * ruby.c (set_arg0): wrong predicate when new $0 value is bigger than original space. * gc.c (id2ref): should use NUM2ULONG() * object.c (rb_mod_const_get): check whether name is a class variable name. * object.c (rb_mod_const_set): ditto. * object.c (rb_mod_const_defined): ditto. * marshal.c (w_float): precision changed to "%.16g" * eval.c (rb_call0): wrong retry behavior. * numeric.c (fix_aref): a bug on long>int architecture. * eval.c (rb_eval_string_wrap): should restore ruby_wrapper. * regex.c (re_compile_pattern): char class at either edge of range should be invalid. * eval.c (handle_rescue): use === to compare exception match. * error.c (syserr_eqq): comparison between SytemCallErrors should based on their error numbers. * eval.c (safe_getter): should use INT2NUM(). * bignum.c (rb_big2long): 2**31 cannot fit in 31 bit long. * regex.c (calculate_must_string): wrong length calculation. * eval.c (rb_thread_start_0): fixed memory leak. * parse.y (none): should clear cmdarg_stack too. * io.c (rb_fopen): use setvbuf() to avoid recursive malloc() on some platforms. * file.c (rb_stat_dev): device functions should honor stat field types (except long long such as dev_t). * eval.c (rb_mod_nesting): should not push nil for nesting array. * eval.c (rb_mod_s_constants): should not search array by rb_mod_const_at() for nil (happens for singleton class). * class.c (rb_singleton_class_attached): should modify iv_tbl by itself, no longer use rb_iv_set() to avoid freeze check error. * variable.c (rb_const_get): error message "uninitialized constant Foo at Bar::Baz" instead of "uninitialized constantBar::Baz::Foo". * eval.c (rb_mod_included): new hook called from rb_mod_include(). * io.c (opt_i_set): should strdup() inplace_edit string. * eval.c (exec_under): need to push cref too. * eval.c (rb_f_missing): raise NameError for "undefined local variable or method". * error.c (Init_Exception): new exception NoMethodError.

It cause variable/method ambiguity. Thanks to L.

* unify Errno exceptions of same errno, or new exception comparison scheme.
* 2.times{|i| if i==0 then a = 15 else puts eval("a") end} should print nil.

Standard Libraries
- Module#define_method which takes a name and a body (block, proc or method).
- Enume#inject
- Array#fetch
- IO::for_fd
- Process::waitall [ruby-talk:4557]
- Process::Status
- File::lchown, File::lchmod; xxx - still need work for non existing platforms
- move Time::times to Process.
- Enumerable#sort_by for Schwartzian transformation
- fork_and_kill_other_threads.
- signal list (Signal::trap, Signal::list).
- move NameError under StandardError.
* array.c (rb_ary_modify): should copy the internal buffer if the modifying buffer is shared. * array.c (ary_make_shared): make an internal buffer of an array to be shared. * array.c (rb_ary_shift): avoid sliding an internal buffer by using shared buffer. * array.c (rb_ary_subseq): avoid copying the buffer. * parse.y (gettable): should freeze __LINE__ string. * io.c (rb_io_puts): old behavoir restored. rationale: a) if you want to call to_s for arrays, you can just call print a, "\n". b) to_s wastes memory if array (and sum of its contents) is huge. c) now any object that has to_ary is treated as an array, using rb_check_convert_type(). * hash.c (rb_hash_initialize): now accepts a block to calculate the default value. [new] * hash.c (rb_hash_aref): call "default" method to get the value corrensponding to the non existing key. * hash.c (rb_hash_default): get the default value based on the block given to 'new'. Now it takes an optinal "key" argument. "default" became the method to get the value for non existing key. Users may override "default" method to change the hash behavior. * hash.c (rb_hash_set_default): clear the flag if a block is given to 'new' * object.c (Init_Object): undef Data.allocate, left Data.new. * ext/curses/curses.c (window_scrollok): use RTEST(). * ext/curses/curses.c (window_idlok): ditto. * ext/curses/curses.c (window_keypad): ditto. * ext/curses/curses.c (window_idlok): idlok() may return void on some platforms; so don't use return value. * ext/curses/curses.c (window_scrollok): ditto for consistency. * ext/curses/curses.c: replace FIX2INT() by typechecking NUM2INT(). * parse.y (str_extend): should not process immature #$x and #@x interpolation, e.g #@#@ etc. * enum.c (enum_sort_by): sort_by does not have to be stable always. * enum.c (enum_sort_by): call qsort directly to gain performance. * util.c (ruby_qsort): ruby_qsort(qs6) is now native thread safe. * error.c (rb_sys_fail): it must be a bug if it's called when errno == 0. * regex.c (WC2MBC1ST): should not pass through > 0x80 number in UTF-8. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@1896 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
