-This document discribes about the 'tcltklib' library. Although there
-is the 'tcltk' library (tcltk.rb) under this directory, no description
-in this document (because it is not maintained recently).
-
-==============================================================
-module TclTklib
- : Defines methods to do operations which are independed on
- : Tcl/Tk interpreters
-
- module TclTkLib::EventFlag
- : Defines flags to define taget events on 'do_one_event' methos.
- : When to give, please use bit-operator (e.g. WINDOW | DONT_WAIT).
-
- [constants]
- NONE
- : Is 0. It means "there is no target". But on the real
- : operation, it is same to ALL.
-
- WINDOW
- : 'window' event is processed.
-
- FILE
- : 'file' event is processed.
-
- TIMER
- : 'timer' event is processed.
-
- IDLE
- : 'idle' operation (e.g. 're-draw'; the operations when the
- : other kinds of events doesn't occur) is processed.
-
- ALL
- : All kinds of events are processed.
- : Same to 'WINDOW | FILE | TIMER | IDLE'.
-
- DONT_WAIT
- : Without this flag, 'do_one_event' waits the occurence of
- : a target event. With this flag, doesn't wait and returns
- : false if there is no target event for processing.
-
- module TclTkLib::VarAccessFlag
- : Defines flags to give '_get_variable' and so on. When to give,
- : please use bit-operator (e.g. GLOBAL_ONLY | LEAVE_ERR_MSG ).
-
- [constants]
- NONE
- : Is 0. It means "set no flag".
-
- GLOBAL_ONLY
- : (site Tcl/Tk's man page)
- : Under normal circumstances the procedures look up
- : variables as follows: If a procedure call is active
- : in interp, a variable is looked up at the current
- : level of procedure call. Otherwise, a variable is
- : looked up first in the current namespace, then in
- : the global namespace. However, if this bit is set
- : in flags then the variable is looked up only in the
- : global namespace even if there is a procedure call
- : active. If both GLOBAL_ONLY and NAMESPACE_ONLY are
- : given, GLOBAL_ONLY is ignored.
- :
- : *** ATTENTION ***
- : Tcl7.6 doesn't have namespaces. So NAMESPACE_ONLY
- : is defined as 0, and then GLOBAL_ONLY is available
- : even if flag is (GLOBAL_ONLY | NAMESPACE_ONLY).
-
- NAMESPACE_ONLY
- : (site Tcl/Tk's man page)
- : Under normal circumstances the procedures look up
- : variables as follows: If a procedure call is active
- : in interp, a variable is looked up at the current
- : level of procedure call. Otherwise, a variable is
- : looked up first in the current namespace, then in
- : the global namespace. However, if this bit is set
- : in flags then the variable is looked up only in the
- : current namespace even if there is a procedure call
- : active.
- :
- : *** ATTENTION ***
- : Tcl7.6 doesn't have namespaces. So NAMESPACE_ONLY
- : is defined as 0.
-
- LEAVE_ERR_MSG
- : (site Tcl/Tk's man page)
- : If an error is returned and this bit is set in flags,
- : then an error message will be left in the interpreter's
- : result, where it can be retrieved with Tcl_GetObjResult
- : or Tcl_GetStringResult. If this flag bit isn't set then
- : no error message is left and the interpreter's result
- : will not be modified.
-
- APPEND_VALUE
- : (site Tcl/Tk's man page)
- : If this bit is set then newValue is appended to the
- : current value, instead of replacing it. If the variable
- : is currently undefined, then this bit is ignored.
-
- LIST_ELEMENT
- : (site Tcl/Tk's man page)
- : If this bit is set, then newValue is converted to a
- : valid Tcl list element before setting (or appending
- : to) the variable. A separator space is appended before
- : the new list element unless the list element is going
- : to be the first element in a list or sublist (i.e. the
- : variable's current value is empty, or contains the
- : single character ``{'', or ends in `` }'').
-
- PARSE_VARNAME
- : (site Tcl/Tk's man page)
- : If this bit is set when calling _set_variable and so
- : on, var_name argument may contain both an array and an
- : element name: if the name contains an open parenthesis
- : and ends with a close parenthesis, then the value
- : between the parentheses is treated as an element name
- : (which can have any string value) and the characters
- : before the first open parenthesis are treated as the
- : name of an array variable. If the flag PARSE_VARNAME
- : is given, index_name argument should be 'nil' since the
- : array and element names are taken from var_name.
- :
- : *** ATTENTION ***
- : Tcl7.6 doesn't have this flag. So PARSE_VARNAME is
- : defined as 0.
-
- [module methods]
- mainloop(check_root = true)
- : Starts the eventloop. If 'check_root' is true, this method
- : doesn't return when a root widget exists.
- : If 'check_root' is false, doen't return by the other
- : reasons than exceptions.
-
- mainloop_watchdog(check_root = true)
- : On the normal eventloop, some kinds of callback operations
- : cause deadlock. To avoid some of such deadlocks, this
- : method starts an eventloop and a watchdog-thread.
-
- do_one_event(flag = TclTkLib::EventFlag::ALL |
- TclTkLib::EventFlag::DONT_WAIT)
- : Do one event for processing. When processed an event,
- : returns true.
- : If NOT set DONT_WAIT flag, this method waits occurrence of
- : a target event.
- : If set DONT_WAIT flag and no event for processing, returns
- : false immediately.
- : If $SAFE >= 4, or $SAFE >= 1 and the flag is tainted,
- : force to set DONT_WAIT flag.
-
- set_eventloop_tick(timer_tick)
- : Define the interval of thread-switching with an integer
- : value of mili-seconds.
- : Default timer_tick is 0. It means that thread-switching
- : is based on the count of processed events.
- : ( see 'set_eventloop_weight' method )
- : However, if the eventloop thread is the only thread,
- : timer_tick cannt be set to 0. If 0, then is set to 100 ms
- : automatically (see NO_THREAD_INTERRUPT_TIME on tcltklib.c).
- : On $SAFE >= 4, cannot call this method.
-
- get_eventloop_tick
- : Get current value of 'timer_tick'
-
- set_no_event_wait(no_event_wait)
- : Define sleeping time of the eventloop when two or more
- : thread are running and there is no event for processing.
- : Default value is 20 (ms).
- : If the eventloop thread is the only thread, this value is
- : invalid.
- : On $SAFE >= 4, cannot call this method.
-
- get_no_event_wait
- : Get current value of 'no_event_wait'.
-
- set_eventloop_weight(loop_max, no_event_tick)
- : Define the weight parameters for the eventloop thread.
- : That is invalid when the eventloop is the only thread.
- : 'loop_max' is the max events for thread-switching.
- : 'no_event_tick' is the increment value of the event count
- : when no event for processing (And then, the eventloop thead
- : sleeps 'no_event_wait' mili-seconds).
- : 'loop_max == 800' and 'no_event_tick == 10' are defalut.
- : On $SAFE >= 4, cannot call this method.
-
- get_eventloop_weight
- : Get current values of 'loop_max' and 'no_event_tick'.
-
- mainloop_abort_on_exception=(bool)
- : Define whether the eventloop stops on exception or not.
- : If true (default value), stops on exception.
- : If false, show a warinig message but ignore the exception.
- : If nil, no warning message and ignore the excepsion.
- : This parameter is sometimes useful when multiple Tk
- : interpreters are working. Because the only one eventloop
- : admins all Tk interpreters, sometimes exception on a
- : interpreter kills the eventloop thread. Even if such
- : situation, when abort_on_exception == false or nil,
- : the eventloop ignores the exception and continue to working.
- : On $SAFE >= 4, cannot call this method.
-
- mainloop_abort_on_exception
- : Get current status of that.
-
- num_of_mainwindows
- : Returns the number of main-windows (root-widget).
- : Because there is only one main-window for one Tk interpreter,
- : the value is same to the number of interpreters which has
- : available Tk functions.
-
- _merge_tklist(str, str, ... )
- : Get a Tcl's list string from arguments with a Tcl/Tk's
- : library function. Each arguemnt is converted to a valid
- : Tcl list element.
-
- _conv_listelement(str)
- : Convert the argument to a valid Tcl list element with
- : Tcl/Tk's library function.
-
- _toUTF8(str, encoding)
- _fromUTF8(str, encoding)
- : Call the function (which is internal function of Tcl/Tk) to
- : convert to/from a UTF8 string.
-
- _subst_UTF_backslash(str)
- _subst_Tcl_backslash(str)
- : Substitute backslash sequence with Tcl's rule (include \uhhhh;
- : give a sixteen-bit hexadecimal value for Unicode character).
- : _subst_Tcl_backslash method parses all backslash sequence.
- : _subst_UTF_backslash method parses \uhhhh only.
-
-class TclTkIp
- [class methods]
- new(ip_name=nil, options='')
- : Generate an instance of TclTkIp class.
- : If 'ip_name' argument is given as a string, it is the name
- : of the Tk interpreter which is shown by 'winfo interps'
- : command.
- : 'options' argument accepts a string which is the command
- : line options of wish; such as '-geometry' or '-use'.
- : The information is used to generate the root widget of the
- : interpreter.
- : ( e.g. TclTkIp.new('FOO', '-geometry 500x200 -use 0x2200009') )
- : If is given nil or falsr for the 'option' argument, generates
- : the Tcl interpreter without Tk library. Then the interpreter
- : doesn't need GUI environment. Therefore, even if a window
- : system doesn't exist or cannot be used, Ruby can control the
- : Tcl interpreter and the extention libraries loaded on the
- : interpreter.
-
- [instance methods]
- create_slave(name, safe=false)
- : Create a slave interpreter.
- : The parent of the interpreter is the receiver of this method.
- : The name of the slave interpreter is given by 'name' argument.
- : The 'safe' argument decides whether the slave interpreter is
- : created as a safe interpreter or not. If true, create a safe
- : interpreter. Default is false. However, if the parent
- : interpreter is a safe interpreter, the created interpreter is
- : a safe interpreter (ignore 'safe' argument value).
- : If $SAFE >= 4, can create a safe interpreter only.
-
- make_safe
- : Make the interpreter to the safe interpreter, and returns
- : self. If fail, raise RuntimeError.
-
- safe?
- : Check whether the interpreter is the safe interpreter.
- : If is the safe interpreter, returns true.
-
- allow_ruby_exit?
- : Return the mode whether 'exit' function of ruby or 'exit'
- : command of Tcl/Tk can quit the ruby process or not on the
- : interpreter. If false, such a command quit the interpreter
- : only.
- : The default value for a master interpreter is true, and
- : for a slave interpreter is false.
-
- allow_ruby_exit=(mode)
- : Change the mode of 'allow_ruby_exit?'.
- : If $SAFE >= 4 or the interpreter is a "safe" interpreter,
- : this is not permitted (raise an exception).
-
- delete
- : Delete the interpreter.
- : The deleted interpreter doesn't accept command and then
- : raise an exception.
-
- deleted?
- : Check whether the interpreter is already deleted.
- : If deleted, returns true.
-
- restart
- : Restart Tk part of the interpreter.
- : Use this when you need Tk functions after destroying the
- : root widget.
- : On $SAFE >= 4, cannot call this method.
-
- _eval(str)
- _invoke(*args)
- : Estimates the arguments as a command on the Tk interpreter.
- : The argument of _eval is a script of Tcl/Tk.
- : Each argument of _invoke is a token of one command line of
- : Tcl/Tk.
- : Because the operation of _invoke doesn't through the
- : command line parser of Tk interpreter, the cost of
- : estimation is smaller than _eval. However, auto_load
- : mechanism of the Tk interpreter doesn't work on _invoke.
- : So _invoke can call only the command which already
- : registered on the interpreter by 'load' command and so on.
- : On _eval command, auto_load mechanism words. So if succeed
- : to _eval and regist the command once, after that, the
- : command can be called by _invoke.
-
- _toUTF8(str, encoding)
- _fromUTF8(str, encoding)
- : Call the function (which is internal function of Tcl/Tk) to
- : convert to/from a UTF8 string.
-
- _thread_vwait(var_name)
- _thread_tkwait(mode, target)
- : 'vwait' or 'tkwait' with thread support.
- : The difference from normal 'vwait' or 'tkwait' command is
- : doing independent wait from the vwait stack when they are
- : called on the other thread than the eventloop thread.
- : In the case of Tcl/Tk's vwait / tkwait, if 2nd vwait /
- : tkwait is called on waiting for 1st vwait / tkwait,
- : returns the order of [2nd]->[1st] regardless of the order
- : of when the wait condition was fulfilled.
- : If _thread_vwait / _thread_tkwait is called on the
- : eventloop thread, there is no difference from vwait /
- : tkwait. But if called on the other thread than the
- : eventloop, stops the thread. And when the wait condition
- : is fulfilled, the thread restarts. The meaning of
- : "independent from the vwait stack" is that the timing of
- : restarting is independent from the waiting status of the
- : other threads. That is, even if the eventloop thread is
- : waiting by vwait and is not fulfilled the condition,
- : _thread_vwait completes the waiting when its waiting
- : condition is fulfilled and the thread which stopped by
- : _thread_vwait can continue the operation.
-
- _return_value
- : Get the last result value on the interpreter.
-
- _get_variable(var_name, flag)
- _get_variable2(var_name, index_name, flag)
- : Get the current value of a variable. If specified a
- : index_name (see also the PARSE_VARNAME flag), get the
- : value of the index_name element.
-
- _set_variable(var_name, value, flag)
- _set_variable2(var_name, index_name, value, flag)
- : Create or modify a variable. If specified a index_name
- : (see also the PARSE_VARNAME flag), create or modify the
- : index_name element.
-
- _unset_variable(var_name)
- _unset_variable2(var_name, index_name)
- : Remove a variable. If specified a index_name (see also
- : the PARSE_VARNAME flag), remove the index_name element.
-
- _get_global_var(var_name)
- _get_global_var2(var_name, index_name)
- _set_global_var(var_name, value)
- _set_global_var2(var_name, index_name, value)
- _unset_global_var(var_name)
- _unset_global_var2(var_name, index_name)
- : Call the associated method with the flag argument
- : (GLOBAL_ONLY | LEAVE_ERR_MSG).
-
- _split_tklist(str)
- : Split the argument with Tcl/Tk's library function and
- : get an array as a list of Tcl list elements.
-
- _merge_tklist(str, str, ... )
- : Get a Tcl's list string from arguments with a Tcl/Tk's

-class TkCallbackContinue < StandardError
- : They are exception classes to break or continue the Tk callback

-本ドキュメントには古い tcltk ライブラリ,tcltklib ライブラリの説明
-が含まれていますが,その記述内容は古いものとなっています.
-
-tcltk ライブラリ(tcltk.rb)は現在ではメンテナンスが事実上行われて
-いないため,古いドキュメントの説明がそのまま有効です.それに対し,
-tcltklib ライブラリについては,現在の Ruby/Tk(tk.rb 以下のライブラ
-リ群)を稼働させるための中心としてメンテナンスされているため,少々
-違いが生じています.
-
-そこで,まず古い説明文書を示した後,現在の tcltklib ライブラリにつ
-いての説明を加えます.
-
-以下がライブラリの古い説明文書です.
-==============================================================
- MANUAL.euc
- Sep. 19, 1997 Y. Shigehiro
-
-以下, 「tcl/tk」という表記は, tclsh や wish を実現している, 一般でいう
-ところの tcl/tk を指します. 「tcltk ライブラリ」, 「tcltklib ライブラ
-リ」という表記は, 本パッケージに含まれる ruby 用のライブラリを指します.
-
-<< tcltk ライブラリ >>
-
-tcl/tk の C ライブラリを利用するための高(中?)水準インターフェースを提
-供します.
-
-このライブラリは ruby から tcl/tk ライブラリを利用するためのもので, 内
-部で tcltklib ライブラリを利用しています.
-
-[説明]
-
-tcl/tk インタプリタでは, ウィジェットに何か指示を送るには, ウィジェッ
-ト名に続いてパラメータを書きます. したがって, ウィジェットがオブジェク
-トであり, それに対してメソッドを送っている, とみなすことができます. さ
-て, tcl/tk インタプリタでは, 組み込みコマンドも, 前述のウィジェットと
-同じような書式の命令で実行されます. すなわち, コマンドもオブジェクトで
-あると考えることができます.
-
-このような考えに基づき, tcltk ライブラリでは, tcl/tk のコマンドやウィ
-ジェットに対応するオブジェクトを生成します. オブジェクトに対するメソッ
-ド呼び出しは, e() メソッドにより実行されます. 例えば, tcl/tk の info
-コマンドに対応する ruby のオブジェクトが info という名前であるとすると,
-tcl/tk の
- info commands
-という命令は tcltk ライブラリでは
- info.e("commands")
-と記述されます. また, 「.」というウィジェット (wish 実行時に自動的に生
-成されるルートウィジェット) に対応する ruby のオブジェクトが root とい
-う名前であるとすると,
- . configure -height 300 -width 300
-という tcl/tk の命令は
- root.e("configure -height 300 -width 300")
-と記述されます. このような記述は, 見ためには美しくありませんが, そして,
-スクリプトを読む人には見づらいかも知れませんが, 実際にスクリプトを書い
-てみると予想外に手軽です.
-
-[使用法]
-
-1. ライブラリを読み込む.
- require "tcltk"
-
-2. tcl/tk インタプリタを生成する.
- ip = TclTkInterpreter.new()
-
-3. tcl/tk のコマンドに対応するオブジェクトを変数に代入しておく.
- # コマンドに対応するオブジェクトが入った Hash を取り出す.
- c = ip.commands()
- # 使いたいコマンドに対応するオブジェクトを個別の変数に代入する.
- bind, button, info, wm = c.indexes("bind", "button", "info", "wm")
-
-4. 必要な処理を行う.
- 詳しくは, サンプルを参照のこと.
-
-5. 準備ができたら, イベントループに入る.
- TclTk.mainloop()
-
-(( 以下, モジュール, クラス等の説明を書く予定.))
-
-
-
-<< tcltklib ライブラリ >>
-
-tcl/tk の C ライブラリを利用するための低水準インターフェースを提供しま
-す.
-
-コンパイル/実行には, tcl/tk の C ライブラリが必要です.
-
-[説明]
-
-このライブラリを用いると, ruby から tcl/tk の C ライブラリを利用できま
-す. 具体的には, ruby インタプリタから tcl/tk インタプリタを呼び出すこ
-とができます. さらに, その(ruby インタプリタから呼び出した) tcl/tk イ
-ンタプリタから, 逆に ruby インタプリタを呼び出すこともできます.
-
-[使用法]
-
-require "tcltklib" すると, 以下のモジュール, クラスが利用可能です.
-
-モジュール TclTkLib
- tcl/tk ライブラリを呼び出すメソッドを集めたモジュールです. ただし,
- tcl/tk インタプリタ関係のメソッドはクラス TclTkIp にあります.
-
- モジュールメソッド mainloop()
- Tk_MainLoop を実行します. 全ての tk のウインドウが無くなると終了
- します(例えば, tcl/tk で書くところの "destroy ." をした場合等).
- 引数: 無し
- 戻り値: nil
-
-クラス TclTkIp
- インスタンスが tcl/tk のインタプリタに対応します. tcl/tk のライブ
- ラリの仕様通り, インスタンスを複数個生成しても正しく動作します(そ
- んなことをする必要はあまり無いはずですが). インタプリタは wish の
- tcl/tk コマンドを実行できます. さらに, 以下のコマンドを実行できま
- す.
- コマンド ruby
- 引数を ruby で実行します(ruby_eval_string を実行します). 引数
- は 1 つでなければなりません. 戻り値は ruby の実行結果です.
- ruby の実行結果は nil か String でなければなりません.
-
- クラスメソッド new()
- TclTkIp クラスのインスタンスを生成します
- 引数: 無し
- 戻り値 (TclTkIp): 生成されたインスタンス
-
- メソッド _eval(script)
- インタプリタで script を評価します(Tcl_Eval を実行します). 前述
- のように, ruby コマンドにより script 内から ruby スクリプトを実
- 行できます.
- 引数: script (String) - インタプリタで評価するスクリプト文字列
- 戻り値 (String): 評価結果 ((Tcl_Interp *)->result)
-
- メソッド _return_value()
- 直前の Tcl_Eval の戻り値を返します. 0(TCL_OK) で正常終了です.
- 引数: 無し
- 戻り値 (Fixnum): 直前の Tcl_Eval() が返した値.

-ActiveTcl is ActiveState's quality-assured distribution of Tcl.
-
-# see <http://www.activestate.com/Products/ActiveTcl/>

-
-If you want to use ActiveTcl binary package as the Tcl/Tk libraries,
-please use the following configure options.
-
- --with-tcl-dir=<ActiveTcl_root>
- --with-tk-dir=<ActiveTcl_root>
-
-And use the followings if you need.

- --with-tk-dir=/usr/local/ActiveTcl/ \
- --with-tcllib=tclstub8.4 \
- --with-tklib=tkstub8.4 \
- --enable-tcltk-stubs
-
-It depends on your environment that you have to add the directory of
-ActiveTcl's libraries to your library path when execute Ruby/Tk.
-One of the way is to add entries to TCLLIBPATH environment variable,
-and one of the others add to LD_LIBRARY_PATH environment variable
-
-Probably, using TCLLIBPATH is better. The value is appended at the
-head of Tcl's 'auto_path' variable. You can see the value of the
-variable by using 'Tk::AUTO_PATH.value' or 'Tk::AUTO_PATH.list'.
-
-For example, on Linux, one of the ways is to use LD_LIBRARY_PATH
-environment variable.
--------------------------------------------------------------------------
- [bash]$ LD_LIBRARY_PATH=/usr/local/ActiveTcl/lib:$LD_LIBRARY_PATH \
- ruby your-Ruby/Tk-script
-
- [bash]$ LD_LIBRARY_PATH=/usr/local/ActiveTcl/lib:$LD_LIBRARY_PATH irb
--------------------------------------------------------------------------
-Based on it, the Tcl interpreter changes auto_path variable's value.
-
-Then, you'll be able to use Tcl/Tk extension libraries included in the
-ActiveTcl package (e.g. call TkPackage.require('BWidget'), and then,
-use functions/widgets of BWidget extention).

- 最初に空ループの時間を測定し, 続いて実際に線を引く時間を測定します.
- tcl/tk は(再)描画のときに backing store を使わずに律義に 10000 本(?)
- 線を引くので, (再)描画を始めると, マシンがかなり重くなります.
-demo/lines0.tcl : wish 用のスクリプト.
-demo/lines1.rb : `tk.rb' 用のスクリプト.
-demo/lines2.rb : tcltk ライブラリ用のスクリプト.
-
-[注意]
-
-コンパイル/実行には, tcl/tk の C ライブラリが必要です.
-
-このライブラリは,
-
- ruby-1.0-970701, ruby-1.0-970911, ruby-1.0-970919
- FreeBSD 2.2.2-RELEASE
- およびそのパッケージ jp-tcl-7.6.tgz, jp-tk-4.2.tgz
-
-で作成/動作確認しました. 他の環境では動作するかどうかわかりません.
-
-TclTkLib.mainloop を実行中に Control-C が効かないのは不便なので, ruby
-のソースを参考に, #include "sig.h" して trap_immediate を操作していま
-すが, ruby の README.EXT にも書いてないのに, こんなことをして良いのか
-どうかわかりません.
-
--d オプションでデバッグ情報を表示させるために, ruby のソースを参考に,
-debug という大域変数を参照していますが, ruby の README.EXT にも書いて
-ないのに, こんなことをして良いのかどうかわかりません.
-
-extconf.rb は書きましたが, (いろいろな意味で)これで良いのか良く分かり
-ません.
-
-[特徴]
-
-ruby から tcl/tk ライブラリを利用できます.
-
-tcl/tk インタプリタのスクリプトは, 機械的に tcltk ライブラリ用の ruby
-スクリプトに変換できます.
-
-(`tk.rb' との違い)
-
-1. tcl/tk インタプリタのスクリプトが, どのように, tcltk ライブラリ用の
- ruby スクリプトに変換されるかが理解できれば, マニュアル類が無いに等
- しい `tk.rb' とは異なり
-
- tcl/tk のマニュアルやオンラインドキュメントを用いて
-
- 効率良くプログラミングを行うことができます.
- 記述方法がわからない, コマンドに与えるパラメータがわからない...
- - Canvas.new { ... } と, なぜイテレータブロックを書けるの??
- - Canvas の bbox は数値のリストを返すのに, xview は文字列を返すの??
- と, いちいち, ライブラリのソースを追いかける必要はありません.
-
-2. 個々の機能(オプション)を個別処理によりサポートしており, そのためサ
- ポートしていない機能は使うことができない(本当は使えないこともないの
- ですが) `tk.rb' とは異なり, tcl/tk インタプリタで可能なことは
-
- ほとんど
-
- ruby からも実行できます. 現在, ruby から実行できないことが確認され
- ているのは,
-
- bind コマンドでスクリプトを追加する構文
- 「bind tag sequence +script」
- ^
-
- のみです.
- - `. configure -width' をしようとして, `Tk.root.height()' と書い
- たのに, `undefined method `height'' と怒られてしまった. tk.rb を
- 読んでみて, ガーン. できないのか...
- ということはありません.
-
-3. wish プロセスを起動しプロセス間通信で wish を利用する `tk.rb' とは
- 異なり, tcl/tk の C ライブラリをリンクし
-
- より高速に (といっても, 思った程は速くないですが)
-
- 処理を行います.
-
-4. `tk.rb' ほど, 高水準なインターフェースを備えていないため, tcl/tk イ
- ンタプリタの生成等
-
- 何から何まで自分で記述
-
- しなければなりません(その代わり, tcl/tk ライブラリの仕様通り,
- tcl/tk インタプリタを複数生成することもできますが).
- インターフェースは(おそらく) ruby の思想に沿ったものではありません.
- また, スクリプトの記述は
-
- ダサダサ
-
- です. スクリプトは, 一見, 読みづらいものとなります. が, 書く人にとっ
- ては, それほど煩わしいものではないと思います.
-
-[インストールの方法]
-
-0. ruby のソースファイル(ruby-1.0-なんたら.tgz)を展開しておきます.
-
-1. ruby-1.0-なんたら/ext に ext/tcltklib をコピーします.
- cp -r ext/tcltklib ???/ruby-1.0-なんたら/ext/
-
-2. ruby のインストール法に従い make 等をします.
-
-3. ruby のライブラリ置場に lib/* をコピーします.
- cp lib/* /usr/local/lib/ruby/
