* eval.c (error_print): should no call "to_str" anymore use "message" method instead. * io.c (rb_f_open): Kernel#open() calls "to_open" if the first argument responds to it. [Ruby2] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@6102 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

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.
|
|
* 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.
|
|
* Thread#max_stack_size attribute (possible??)
|

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.
|
|
- Integer#to_s(base)
|
|
- Hash::new{default}
|
|
- hash etc. should handle self referenceing array/hash
|
|
- Array#select(n1,n2...) works like Array#indexes(n1,n2...)
|
|
- use Mersenne Twister RNG for random.
|
|
- deprecate Array#indexes, and Array#indices.
|
|
- remove dependency on MAXPATHLEN.
|
|
- String#scanf(?)
|
|
* Object#fmt(?)
|
|
* Time::strptime
|
|
* Integer[num], Float[num]; Fixnum[num]?
|
|
* method to retrieve non-number trailer for to_i/to_f.
|
|
* Stream or Port, abstract superclass of IO ?
|
|
* String#{pred,prev}, String#downto
|
|
* optional stepsize argument for succ()
|
|
* Ruby module -- Ruby::Version, Ruby::Interpreter
|
|
* introduce Boolean class; super of TrueClass, FalseClass
|
|
* synchronized method - synchronized{...}, synchronized :foo, :bar

|
|
* marshal should not depend on sprintf (works bad with locale).
|
|
* ternary arg pow: a.pow(b,c) == a**b%c
|
|
* new caller(), e.g. call_stack; needs better name.
|
|
* pointer share mechanism similar to one in String for Array.
|
|
* require "1.6" etc. by /usr/lib/ruby/1.6/1.6.rb ;-)
|
