* tkafter.rb: Add self to 1st argument of interval- and loop-proc
TkAfter#current_interval returns an interval (sleep) time value
TkAfter#current_args returns an array of arguments
TkAfter#return_value returns a return value of last loop-proc
e.g.
TkAfter.new(
proc{|obj| 500 - obj.current_interval}, 10,
[proc{|obj| p obj.current_args}, 'proc', 1],
proc{|obj| p obj.current_args; ['return', 2]},
[proc{|obj|
p obj.return_value
p ['proc', obj.current_args[0].call(obj.return_value[1],
obj.current_args[1])]},
proc{|*args| args[0] + args[1]}, 1],
proc{p ['proc', 4]} ).start(100)
* tk*.rb: Allow to use Symbols for parameters.
Allow new notation of constructor (also allow old notation).
e.g.
TkFrame.new('classname'=>'User'){|base|
pack
f = TkFrame.new(base, :classname=>'ButtonFrame').pack
TkButton.new(
:parent => f,
:text => 'Quit',
:command => proc{exit}
).pack(
:fill => :x,
:pady => 2
)
}
* tkcanvas.rb: (TkcItem) Add 'coords' parameter to the canvas item
constructor (for new notation of constructor).
e.g.
c = TkCanvas.new.pack
l = TkcLine.new(c, :coords=>[[0,0], [100,100]])
* tcltklib.c: New 'mainloop' and 'mainloop_watchdog'.
The priority of their event-loop can be controlled.
They accept an optional argument.
If it false, they don't exit although the root widget is destroyed.
This function is sometimes useful, if it is used with 'restart'.
'mainloop' can't treat Thread#join/value in a callback routine.
(e.g. TkButton.new(:command=>proc{p Thread.new{button.invoke}.value}) )
'mainloop_watchdog' can treat them, but watchdog thread is always running
(so, a little heavier than 'mainloop').
If the purpose of using Thread#join/value is to do something under some
safe-level, please use Proc object.
(e.g. :command=>proc{$SAFE=1;proc{$SAFE=2;button.invoke}.call;p $SAFE})
* tk.rb: Support functions of new 'mainloop' and 'mainloop_watchdog'.
* tk.rb: (Tk.restart) Add 'app-name' paramater and 'use' parameter.
'app-name' specifies the name and the resource class of the
application. If 'app-name' is specified to 'xxx', the application
class on the resource database is set to 'Xxx' and the application
name is changed by the same rule of Tk.appname method. 'use'
specifies the main window for embedding the root widget instead of
generating a new window.
* tk.rb: Add new parameter 'widgetname' to the widget constructor to
support effective use of Resource Database. For example, the
resource 'Xxx*quit.text: QUIT' can set the text of the button
generated by the following code.
e.g.
Tk.restart('Xxx')
TkButton.new(nil, 'widgetname'=>'quit', 'command'=>proc{exit}).pack
Tk.mainloop
* tk.rb: TkOption::get always returns a tainted string.
Add TkOption::new_proc_class.
It generates a class to import procedures defined on the resource
database. For example, there is a following resource file.
----< resource-test >------------
*CMD.foo: {|*args| p [$SAFE, :foo, args]}
*CMD.XXX.bar: {|*args| p [$SAFE, :bar, args]}
*Button.command: ruby {p self; p $SAFE; TkOption::CMD::XXX.bar(1,2,3)}
---------------------------------
The following code is a sample of use of the resource file.
e.g.
require 'tk'
TkOption.readfile 'resource-test'
p TkOption.new_proc_class(:CMD, [:foo], 1)
p TkOption.new_proc_class(:XXX, [:bar], 2, false, TkOption::CMD)
TkButton.new(:text=>'test').pack
Tk.mainloop

* What's Ruby
Ruby is the interpreted scripting language for quick and
easy object-oriented programming. It has many features to
process text files and to do system management tasks (as in
Perl). It is simple, straight-forward, and extensible.
* Features of Ruby
+ Simple Syntax
+ *Normal* Object-Oriented features(ex. class, method calls)
+ *Advanced* Object-Oriented features(ex. Mix-in, Singleton-method)
+ Operator Overloading
+ Exception Handling
+ Iterators and Closures
+ Garbage Collection
+ Dynamic Loading of Object files(on some architecture)
+ Highly Portable(works on many UNIX machines, and on DOS,
Windows, Mac, BeOS etc.)
* How to get Ruby
The Ruby distribution can be found on:
ftp://ftp.ruby-lang.org/pub/ruby/
You can get it by anonymous CVS. How to check out is:
$ cvs -d :pserver:anonymous@cvs.ruby-lang.org:/src login
(Logging in to anonymous@cvs.ruby-lang.org)
CVS password: anonymous
$ cvs -z4 -d :pserver:anonymous@cvs.ruby-lang.org:/src checkout ruby
* Ruby home-page
The URL of the Ruby home-page is:
http://www.ruby-lang.org/
* Mailing list
There is a mailing list to talk about Ruby.
To subscribe this list, please send the following phrase
subscribe YourFirstName YourFamilyName
e.g.

in the mail body (not subject) to the address <ruby-talk-ctl@ruby-lang.org>.
* How to compile and install
This is what you need to do to compile and install Ruby:
1. If ./configure does not exist or is older than configure.in,
run autoconf to (re)generate configure.
2. Run ./configure, which will generate config.h and Makefile.
3. Edit defines.h if you need. Probably this step will not need.
4. Remove comment mark(#) before the module names from ext/Setup (or
add module names if not present), if you want to link modules
statically.
If you don't want to compile non static extension modules
(probably on architectures which does not allow dynamic loading),
remove comment mark from the line "#option nodynamic" in
ext/Setup.
5. Run make.
6. Optionally, run 'make test' to check whether the compiled Ruby
interpreter works well. If you see the message "test succeeded",
your ruby works as it should (hopefully).
7. Run 'make install'
You may have to be a super user to install ruby.
If you fail to compile ruby, please send the detailed error report with
the error log and machine/OS type, to help others.
