VALUE型をこれらにキャストするためにRで始まる構造体名を全て大文字に した名前のマクロが用意されている. 変数・定数 Qnil 定数: nilオブジェクト Qself 変数: 現在のselfオブジェクトの値. 一般にメソッドにはselfを指す引数 が与えられるので, この変数にアクセスする必要はない. この変数の値を 変更する時は以後のselfの値そのものが変わってしまうので, 特別な事情 がない限り代入してはならない. 注意: ヘッダファイル"env.h"をインクルードしていないファイルでは, Qselfは定数であり, 代入は文法エラーとなる. TRUE 定数: tオブジェクト(真のデフォルト値) FALSE 定数: nilオブジェクト クラス・モジュール定義 VALUE rb_define_class(char *name, VALUE super) superのサブクラスとして新しいRubyクラスを定義する. VALUE rb_define_module(char *name) Rubyモジュールを定義する. void rb_include_module(VALUE class, VALUE module) モジュールをインクルードする. classがすでにmoduleをインクルードして いる時には何もしない(多重インクルードの禁止). 大域変数 void rb_define_variable(char *name, VALUE *var, VALUE (*get_hook), VALUE (*set_hook)(), void *data) RubyとCとで共有するグローバル変数を定義する. get_hookがQnilでない時, 変数参照の際にget_hookにセットされた関数が呼ばれる. set_hookがQnil でない時には代入の時にset_hookが呼ばれる. hook関数には変数名を示す ID，(set hookの場合新しい値も)とともにdataで与えたデータが引数とし て渡される. 変数名が`$'で始まらない時には自動的に追加される. 変数名としてrubyの 識別子として許されない文字(例えば` ')を含む場合にはrubyプログラムか らアクセスできなくなる. void rb_global_variable(VALUE *var) GCのためRubyからはアクセスされないが, Rubyオブジェクトを含む大域変 数をマークする. void rb_read_only_hook() 読み出し専用の変数のためのset_hook関数. 値を設定しようとすると例外 を発生させる. クラス定数 void rb_define_const(VALUE class, char *name, VALUE val) クラス定数を定義する. メソッド定義 rb_define_method(VALUE class, char *name, VALUE (*func)(), int argc) メソッドを定義する. argcはselfを除く引数の数. argcが-1の時, 関数に は引数の数(selfを含まない)を第1引数, 引数の配列を第2引数とする形式 で与えられる. argcが-2の時, 引数はself, args(argsは引数を含むrubyの 配列)という形式で与えられる. rb_define_single_method(VALUE class, char *name, VALUE (*func)(), int argc) 特異メソッドを定義する. 引数はrb_define_method()と同じ. rb_scan_args(VALUE args, char *fmt, ...) args形式で与えられた引数を分解する. fmtは必須引数の数, 付加引数の数, 残りの引数があるかを指定する文字列で, "数字数字*"という形式である. 2 番目の数字と"*"はそれぞれ省略可能である. 第3引数以降は変数へのポ インタで, 該当する要素がその変数に格納される. 付加引数に対応する引 数が与えられていない場合は変数にQnilが代入される. Rubyメソッド呼び出し VALUE rb_funcall(VALUE recv, ID mid, int narg, ...) メソッド呼び出し. 文字列からmidを得るためにはrb_intern()を使う. rb_call_super(VALUE args) スーパークラスのメソッドを呼び出す. argsは引数リストとなる配列. args がQnilの時は現在のメソッドの引数をそのまま引き継ぐ. 文字列 <-> ID変換 ID rb_intern(char *name) 文字列に対応するIDを返す. char *rb_id2name(ID id) IDに対応する文字列を返す(デバッグ用). char *rb_class2name(VALUE class) classの名前を返す(デバッグ用). classが名前を持たない時には, 一番近 い名前を持つクラスの名前を返す. インスタンス変数 VALUE rb_iv_get(VALUE obj, char *name) objのインスタンス変数の値を得る. `@'で始まらないインスタンス変数は Rubyプログラムからアクセスできない. VALUE rb_iv_set(VALUE obj, char *name, VALUE val) objのインスタンス変数をvalにセットする. 制御構造 VALUE rb_iterate(VALUE (*func1)(), char *arg1, VALUE (*func2)(), char *arg2) func2をブロックとして設定し, func1をイテレータとして呼ぶ. func1に は arg1が引数として渡され, func2には第1引数にイテレータから与えられ た値, 第2引数にarg2が渡される. VALUE rb_yield(VALUE val) valを値としてイテレータブロックを呼び出す. VALUE rb_resque(VALUE (*func1)(), char *arg1, VALUE (*func2)(), char *arg2) 関数func1をarg1を引数に呼び出す. func1の実行中に例外が発生した時に は func2をarg2を引数として呼ぶ. 戻り値は例外が発生しなかった時は func1の戻り値, 例外が発生した時にはfunc2の戻り値である. VALUE rb_ensure(VALUE (*func1)(), char *arg1, VALUE (*func2)(), char *arg2) 関数func1をarg1を引数として実行し, 実行終了後(たとえ例外が発生して も) func2をarg2を引数として実行する. 戻り値はfunc1の戻り値である(例 外が発生した時は戻らない). 例外・エラー void Warning(char *fmt, ...) 標準エラー出力に警告情報を表示する. 引数はprintf()と同じ. void Fail(char *fmt, ...) 例外を発生させる. 引数はprintf()と同じ. void Fatal(char *fmt, ...) 致命的例外を発生させる. 通常の例外処理は行なわれず, インタープリタ が終了する(ただしensureで指定されたコードは終了前に実行される). void Bug(char *fmt, ...) インタープリタなどプログラムのバグでしか発生するはずのない状況の時 呼ぶ. インタープリタはコアダンプし直ちに終了する. 例外処理は一切行 なわれない. rubyの初期化・実行 void ruby_init(int argc, char **argv, char **envp) rubyインタプリタの初期化を行なう. void ruby_run() rubyインタプリタを実行する. void ruby_script(char *name) rubyのスクリプト名($0)を設定する. /* * Local variables: * fill-column: 70 * end: */ ./ruby-0.63/ChangeLog100644 150 1 3467 5675464071 12760 0ustar matzdaemonTue Dec 20 00:46:19 1994 Yukihiro Matsumoto (matz@dyna) * 0.63 released * eval.c(rb_call): superの呼び出しで落ちる．argc, argvの設定を忘れ ていた． * parse.y(read_escape): 展開エラー． * variable.c: 定義済みの変数のhookを変更しないように． Mon Dec 19 12:01:10 1994 Yukihiro Matsumoto (matz@ix-02) * parse.y(cond): 条件式に代入式が置かれた場合，`-v'オプションで警 告が出るように． * parse.y(**): 冪乗演算子`**'の優先順位を単項演算子より高くした． * parse.y(and,or): 優先順位の低い演算子`and', `or'. * 0.62 released. * eval.c: 不必要になったPUSH_ENV, POP_ENVを減らした． * env.h: ENVIONからselfをはずした．PUSH_ENVはsuperの準備のためだけ に用いることにした． * eval.c: 下記のオブジェクト化で遅くなった実行速度をもとに戻した． Mon Dec 17 23:01:10 1994 Yukihiro Matsumoto (matz@ix-02) * eval.c: env.{argv,argc}とscope.local_varsのオブジェクト化． * eval.c: 1スコープ内で複数Blockを生成したときのバグを修正． Fri Dec 16 15:52:06 1994 Yukihiro Matsumoto (matz@ix-02) * parse.y: `&&'と`||'の両辺はいつでも条件式とした． Thu Dec 15 00:16:04 1994 Yukihiro Matsumoto (matz@dyna) * eval.c(Block): Blockオブジェクトを実現． * node.h: NODE_QLISTはなくなった． * eval.c(rb_call): 引数への代入を名前で一つずつ代入するのをやめて， 一度にコピーするようにした． * eval.c(rb_call): rubyで記述されたメソッドへの引数渡しをinline化． * eval.c: イテレータ判定処理の全面書き換え．不適切なイテレータ呼び 出しをなくした．例えば「[foo(),bar()]{i|baz(i)}」でfooもbarもイ テレータとして呼び出され*ない*． * eval.c(rb_call): SCOPE処理をinline化．メソッド呼び出しの若干の高 速化． Wed Dec 14 18:09:33 1994 Yukihiro Matsumoto (matz@ix-02) * node.h: nodeもオブジェクトにする．よってGCで回収される． Thu Dec 8 14:17:29 1994 Yukihiro Matsumoto (matz@ix-02) * 0.60 released - alpha test baseline. ./ruby-0.63/FAQ100644 150 1 4754 5674170241 11530 0ustar matzdaemon.\" FAQ - -*- Indented-Text -*- created at: Tue Jan 4 12:48:12 JST 1994 これはRubyに関するFAQ(Frequently Asked Question)をまとめたものです. Emacsでこのファイルを見ている場合にはM-2 C-x $で質問の部分だけを読むこ とができます. C-x $で全てを読む状態に戻せます. ------------------------------ 1) Rubyの名称の由来は Rubyは何かの略称ではなく, 赤い宝石の名前をとって名付けられました. perl(pearlは6月の誕生石)の次を目指す(Rubyは7月の誕生石)という意味 があります. 更に美しく価値あるものであって欲しいという願いも含まれ ています. ------------------------------ 2) Rubyが影響を受けた言語は? Rubyの言語仕様はC, Perl, Eiffelの各言語にこの順に影響を受けていま す. その他に影響を受けた言語としてはtcl, AWK, bourne shell, CLU, Icon, Sather, Smalltalk, Emacs Lispなどがあります. ------------------------------ 3) Rubyの特徴は? 以下に箇条書にします. + インタプリタであり, 手軽にプログラムできる. + 変数宣言が要らない. + ファイルやストリームなどへのUNIX的な操作が簡単にできる. + バイナリファイルも扱える. + きちんとしたオブジェクト指向言語である. + 特異メソッドの機能が提供されている. + モジュールによる機能の共有ができる. + 例外処理機能がある. + GCがあるのでメモリ管理を気にしなくて済む. + 一貫性のある言語仕様. + 複雑なデータ構造も扱える. + ダイナミックロードをサポートする(システムによる). 逆に欠点は - 発展途上で機能が少ない. - デバッガが(まだ)ない. - 遅い. ことでしょうか. ------------------------------ 4) Rubyに変数宣言がないことのメリットは? ある変数がどのスコープに属するかが一目で分かるので, プログラムの読み 易さ, 理解し易さが増すことが最大のメリットです. またトータルのタイプ 量が減るので書き易さ, 手軽さにも貢献します. ------------------------------ 5) RubyとPerlの違いは? RubyとPerlはテキスト操作に優れたスクリプト言語であるという点で, カ バーする範囲が近く, 一見するとライバルに見えます. 確かにRubyの設計 において「Perlにできることはできるように」ということは, 一つの重要 な目標でした. しかし, Rubyの真の目的はあくまでも「手軽なオブジェク ト指向言語」であり, また, Ruby設計の3大目標である, 機能性・一貫性・ 拡張性の結果として, RubyはPerlとは異なる言語になりました. RubyはPerlほど「何でもあり」ではありませんし, ほとんどの場合Perlよ り処理速度が遅いです. しかし, Rubyのオブジェクト指向機能はPerlでは 満足できない人たちにアピールすると思います. ------------------------------ Local variables: fill-column: 70 end: ./ruby-0.63/Makefile.in100644 150 1 10107 5675464072 13261 0ustar matzdaemonSHELL = /bin/sh #### Start of system configuration section. #### srcdir = @srcdir@ VPATH = @srcdir@ CC = @CC@ DBMCC = cc YACC = @YACC@ INSTALL = @INSTALL@ INSTALL_PROGRAM = @INSTALL_PROGRAM@ INSTALL_DATA = @INSTALL_DATA@ CFLAGS = -g LDFLAGS = @STATIC@ $(CFLAGS) LIBS = @LIBS@ DEFS = @DEFS@ MISSING = @LIBOBJS@ @ALLOCA@ prefix = /usr/local binprefix = exec_prefix = $(prefix) bindir = $(exec_prefix)/bin #### End of system configuration section. #### HDRS = defines.h \ dln.h \ getopt.h \ ident.h \ io.h \ node.h \ re.h \ regex.h \ ruby.h \ st.h \ version.h OBJS = array.o \ bignum.o \ class.o \ compar.o \ dbm.o \ dict.o \ dir.o \ dln.o \ enum.o \ error.o \ etc.o \ eval.o \ file.o \ fnmatch.o \ gc.o \ getopt.o \ getopt1.o \ glob.o \ gnuglob.o \ inits.o \ io.o \ main.o \ math.o \ numeric.o \ object.o \ pack.o \ parse.o \ process.o \ random.o \ range.o \ re.o \ regex.o \ ruby.o \ signal.o \ socket.o \ sprintf.o \ st.o \ string.o \ struct.o \ time.o \ variable.o \ version.o \ $(MISSING) PROGRAM = ruby all: $(PROGRAM) $(PROGRAM): $(OBJS) @rm -f $(PROGRAM) $(CC) $(LDFLAGS) $(OBJS) $(LIBS) -o $(PROGRAM) $(bindir)/$(PROGRAM): $(PROGRAM) $(INSTALL_PROGRAM) $(PROGRAM) $(bindir)/$(PROGRAM) install: $(bindir)/$(PROGRAM) clean:; @rm -f $(OBJS) realclean:; @rm -f $(OBJS) @rm -f core ruby *~ config.status Makefile .c.o: $(CC) $(CFLAGS) $(CPPFLAGS) -c $< dbm.o:dbm.c $(DBMCC) $(CFLAGS) $(CPPFLAGS) -c dbm.c alloca.o: missing/alloca.c $(CC) -I. $(CFLAGS) $(CPPFLAGS) -c missing/alloca.c memmove.o: missing/memmove.c $(CC) $(CFLAGS) $(CPPFLAGS) -c missing/memmove.c mkdir.o: missing/mkdir.c $(CC) $(CFLAGS) $(CPPFLAGS) -c missing/mkdir.c strerror.o: missing/strerror.c $(CC) $(CFLAGS) $(CPPFLAGS) -c missing/strerror.c strdup.o: missing/strdup.c $(CC) $(CFLAGS) $(CPPFLAGS) -c missing/strdup.c strftime.o: missing/strftime.c $(CC) -I. $(CFLAGS) $(CPPFLAGS) -c missing/strftime.c strstr.o: missing/strstr.c $(CC) $(CFLAGS) $(CPPFLAGS) -c missing/strstr.c strtol.o: missing/strtol.c $(CC) $(CFLAGS) $(CPPFLAGS) -c missing/strtol.c strtoul.o: missing/strtoul.c $(CC) $(CFLAGS) $(CPPFLAGS) -c missing/strtoul.c # Prevent GNU make v3 from overflowing arg limit on SysV. .NOEXPORT: ### parse.o : parse.y ruby.h defines.h config.h env.h node.h st.h ident.h regex.h ### array.o: array.c ruby.h config.h defines.h bignum.o: bignum.c ruby.h config.h defines.h class.o: class.c ruby.h config.h defines.h env.h node.h st.h compar.o: compar.c ruby.h config.h defines.h dbm.o: dbm.c ruby.h config.h defines.h dict.o: dict.c ruby.h config.h defines.h st.h dir.o: dir.c ruby.h config.h defines.h dln.o: dln.c defines.h dln.h enum.o: enum.c ruby.h config.h defines.h error.o: error.c ruby.h config.h defines.h env.h etc.o: etc.c ruby.h config.h defines.h eval.o: eval.c ruby.h config.h defines.h ident.h env.h node.h st.h file.o: file.c ruby.h config.h defines.h io.h fnmatch.o: fnmatch.c fnmatch.h gc.o: gc.c ruby.h config.h defines.h env.h st.h glob.o: glob.c ruby.h config.h defines.h fnmatch.h gnuglob.o: gnuglob.c fnmatch.h inits.o: inits.c ruby.h config.h defines.h io.o: io.c ruby.h config.h defines.h io.h main.o: main.c math.o: math.c ruby.h config.h defines.h numeric.o: numeric.c ruby.h config.h defines.h env.h object.o: object.c ruby.h config.h defines.h env.h node.h st.h pack.o: pack.c ruby.h config.h defines.h process.o: process.c ruby.h config.h defines.h st.h random.o: random.c ruby.h config.h defines.h range.o: range.c ruby.h config.h defines.h re.o: re.c ruby.h config.h defines.h re.h regex.h regex.o: regex.c defines.h regex.h ruby.o: ruby.c ruby.h config.h defines.h re.h regex.h getopt.h socket.o: socket.c ruby.h config.h defines.h io.h sprintf.o: sprintf.c ruby.h config.h defines.h st.o: st.c st.h string.o: string.c ruby.h config.h defines.h re.h regex.h struct.o: struct.c ruby.h config.h defines.h env.h time.o: time.c ruby.h config.h defines.h variable.o: variable.c ruby.h config.h defines.h env.h node.h ident.h st.h version.o: version.c ruby.h config.h defines.h version.h ./ruby-0.63/README100644 150 1 4317 5674170241 12051 0ustar matzdaemon.\" README - -*- Text -*- created at: Wed Aug 3 11:57:36 JST 1994 コンパイル・インストール 1. configureを実行してMakefileを生成する. 2. (必要ならば)defines.hを編集する. 3. makeを実行してコンパイルする 4. make install もし, コンパイル時にエラーが発生した場合にはエラーのログとマ シン, OSの種類を含むできるだけ詳しいレポートを作者に送ってい ただきたい. 機能追加 Cコードを書くことによって, 簡単にrubyに機能を追加できる. そのおおまかな手順は以下の通りである. * 関数的メソッドを追加する場合 (1) Cで関数を書く (2) rb_define_method()でカーネルクラスのメソッドとして関 数をrubyに登録する関数を書く (3) init.cを編集して, 登録する関数を呼び出す * クラスを追加する場合 (1) クラスを設計する (2) メソッドをCで記述する (3) rb_define_class()でクラスを生成するコードを書く (4) rb_define_method()でメソッドを登録するコードを書く (5) init.cを編集して, 初期化する関数を呼び出す 詳しくはC-IFを参照. 移植 UNIXであればconfigureがほとんどの差異を吸収してくれるはず だが, 思わぬ見落としがあった場合(あるに違いない), 作者にレ ポートすれば, 解決できるかも知れない. アークテクチャにもっとも依存するのはGC部である. rubyのGCは 対象のアーキテクチャがsetjmp()によって, 全てのレジスタを jmp_bufに格納することと, jmp_bufとスタックが32bitアライン メントされていることを仮定している. 前者が真実でない場合の 移植は困難を極めるだろう. 後者は割と簡単に解決できる. gc.c のスタックをマークする部分にアラインメントのバイト数だけず らしてマークするコードを追加するだけで済む. sparc以外のレジスタウィンドウを持つCPUでは, レジスタウィン ドウをフラッシュするコードを追加する必要があるかも知れない. 配布条件 Rubyは最終的にはGNU Public Licenseにしたがった条件で配布さ れる予定だが, 現時点では以下の条件で配布する. * 更新 いかなる目的であれ自由である. ただし, バグ修正は作者への フィードバックを期待する(強制ではない) * 他のプログラムへの引用 いかなる目的であれ自由である. ただし, 配布したコードに含 まれる他の作者によるコードは, それぞれの作者の意向による 制限が加えられる. * 再配布 禁止する. 入手したい人は作者に直接連絡をとること. これは Rubyの言語仕様が不安定な状態のまま広く流布するのを制限す るためであり, 言語仕様が安定した時点で再配布自由とする. ./ruby-0.63/ToDo100644 150 1 421 5674170241 11731 0ustar matzdaemon* format機能 * here document * perlのようなsetuid check * trからBSDコードを取り除く(またはcopyrightをはっきりさせる) * 適切なsignal handling * dlnのCOFF対応 * rubyで定義する変数hookの実現 * write debugger for ruby * re-write regex code for speeding * byte code interpretor ./ruby-0.63/array.c100644 150 1 44324 5674170241 12475 0ustar matzdaemon/************************************************ array.c - $Author: matz $ $Date: 1994/12/06 09:29:47 $ created at: Fri Aug 6 09:46:12 JST 1993 Copyright (C) 1994 Yukihiro Matsumoto ************************************************/ #include "ruby.h" VALUE C_Array;

If the caller did not specify anything, the default is REQUIRE_ORDER if the environment variable POSIXLY_CORRECT is defined, PERMUTE otherwise. REQUIRE_ORDER means don't recognize them as options; stop option processing when the first non-option is seen. This is what Unix does. This mode of operation is selected by either setting the environment variable POSIXLY_CORRECT, or using `+' as the first character of the list of option characters. PERMUTE is the default. We permute the contents of ARGV as we scan, so that eventually all the non-options are at the end. This allows options to be given in any order, even with programs that were not written to expect this. RETURN_IN_ORDER is an option available to programs that were written to expect options and other ARGV-elements in any order and that care about the ordering of the two. We describe each non-option ARGV-element as if it were the argument of an option with character code 1. Using `-' as the first character of the list of option characters selects this mode of operation. The special argument `--' forces an end of option-scanning regardless of the value of `ordering'.

If an element of ARGV starts with '-', and is not exactly "-" or "--", then it is an option element. The characters of this element (aside from the initial '-') are option characters. If `getopt' is called repeatedly, it returns successively each of the option characters from each of the option elements. If `getopt' finds another option character, it returns that character, updating `optind' and `nextchar' so that the next call to `getopt' can resume the scan with the following option character or ARGV-element. If there are no more option characters, `getopt' returns `EOF'. Then `optind' is the index in ARGV of the first ARGV-element that is not an option. (The ARGV-elements have been permuted so that those that are not options now come last.) OPTSTRING is a string containing the legitimate option characters. If an option character is seen that is not listed in OPTSTRING, return '?' after printing an error message. If you set `opterr' to zero, the error message is suppressed but we still return '?'. If a char in OPTSTRING is followed by a colon, that means it wants an arg, so the following text in the same ARGV-element, or the text of the following ARGV-element, is returned in `optarg'. Two colons mean an option that wants an optional arg; if there is text in the current ARGV-element, it is returned in `optarg', otherwise `optarg' is set to zero. If OPTSTRING starts with `-' or `+', it requests different methods of handling the non-option ARGV-elements. See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. Long-named options begin with `--' instead of `-'. Their names may be abbreviated as long as the abbreviation is unique or is an exact match for some defined option. If they have an argument, it follows the option name in the same ARGV-element, separated from the option name by a `=', or else the in next ARGV-element. When `getopt' finds a long-named option, it returns 0 if that option's `flag' field is nonzero, the value of the option's `val' field if the `flag' field is zero. The elements of ARGV aren't really const, because we permute them. But we pretend they're const in the prototype to be compatible with other systems. LONGOPTS is a vector of `struct option' terminated by an element containing a name which is zero. LONGIND returns the index in LONGOPT of the long-named option found. It is only valid when a long-named option has been found by the most recent call.

Rubyは「UNIXで手軽にオブジェクト指向プログラミング」をしたいという望み を実現するために生まれた．そのために必要だと思われた性質は: * 文法や機能が単純である． * オブジェクト指向プログラミングをサポートする機能を 持つ言語として設計されている． * ターンアラウンドタイムが短い(インタプリタである)． * OS(UNIX)の機能が簡単に利用できる． * スクリプト言語として使える． * 処理系がfreeである． などである．オブジェクト指向言語として一般的であるSmalltalkやC++などは 上の条件の一部を満たしてはいるが，特に手軽なプログラミングという点に欠 けており，以上の条件の全てを満たすものではなかった．一方スクリプト言語 であるPerlや Tclにオブジェクト指向機能を追加したシステムも存在するが， これらは「手軽にプログラミング」という性質は満たしてはいても，逆にオブ ジェクト指向機能に不備や不満があった．よって，これらの条件を満たすため に設計されたRubyの特徴は: * インタプリタである． * 単純で例外の少ない文法． * 十分なオブジェクト指向機能を持つ． * できるだけ書きやすい(演算子形式など)． * ガーベージコレクタがある． * 例外処理機能がある． * 十分に強力なクラスが組み込まれている． * OSをアクセスする機能が提供される． * 拡張しやすい． などである．RubyはshやPerlを知っている人にとっての常識になるたけ従った ので，それらの言語からの自然な移行が可能であると思われる．プログラマが Rubyのオブジェクト指向機能について学べば，より強力なこともできるように なるだろう． 更にC言語でクラスやメソッドを記述し，追加することでRubyを更に強力にす ることができる．一部のプラットフォームではRubyは動的にオブジェクトファ イルをリンクできるし，そうでなくてもRubyを再コンパイルして組み込みクラ スを追加するのは容易である(Perlなどよりもはるかに容易である)． * Rubyの文法 ここではRuby言語の文法を解説する．Rubyの基本的な部分は小さく，文法に例 外が少ないので身につけるのはさほど難しくないだろう． ** コメント スクリプト言語の習慣にならい，文字列中以外の'#'から行末まではコメント と見なす． ** 区切り記号 空白文字(タブとスペース)および改行(\n)が区切り記号となる．更に 改行は a + b のように行が式(文)の途中で終り，次の行に続くことが明白な場合以外は文の 区切りとしても認識される． ** 予約語 予約語は以下の通りである break end module self while case ensure nil super yield class fail protect then __END__ continue for redo undef __FILE__ def if resque unless __LINE__ else in retry until elsif include return when 予約語はクラス名，メソッド名，変数名などに用いることはできない． ** 式 Rubyプログラムを構成する要素は式と文である．まず，式から解説する． *** リテラル プログラム中に直接記述できるオブジェクトをリテラルと呼ぶ．Rubyのリテラ ルには文字列，正規表現，数値というリテラルがある． **** 文字列リテラル "..." # バックスラッシュの解釈と変数展開あり '...' # バックスラッシュの解釈なし(\\と\'は解釈する) **** バックスラッシュ記法 \t タブ(0x09) \n 改行文字(0x0a) \r 復帰文字(0x0d) \f 改ページ文字(0x0c) \b バックスペース(0x08) \a ベル(0x07) \e エスケープ(0x1b) \# 文字`#'そのもの \nnn 8進数表記(nは0-7) \xnn 16進数表記(nは0-9,a-f) \^c コントロール文字(cはASCII文字) \C-c コントロール文字(同上) \M-c メタ文字(c|0x80) \それ以外 文字そのもの **** 変数展開 ダブルクォート(`"')で囲まれた文字列と正規表現の中では `#{変数名}'とい う形式で変数の内容を展開することができる．変数が変数記号(`$',`@',`%') で始まる場合には`#変数名'という形式でも展開できる．文字`#'に続く文字 が `{',`$',`@',`%'でなければ，そのまま`#'として解釈される． **** 正規表現リテラル /.../ ^ 行頭 $ 行末 . 任意の1文字 \w 英数字．[0-9A-Za-z_]と同じ \W 非英数字 \s 空白文字．[ \t\n\r\f]と同じ \S 非空白文字 \d 数字．[0-9] と同じ \D 非数字 \b 語境界文字(文字クラス外) \B 非語境界文字 \b 後退(0x08)(文字クラス内) [ ] 文字クラス指定 * 直前の表現の0回以上の繰り返し + 直前の表現の1回以上の繰り返し {m,n} m回からn回の繰り返し ? 0または1回 | 選択 ( ) 正規表現をまとめる その他に文字列と同じバックスラッシュ記法も有効である． **** ワイルドカードリテラル <...> * 任意の文字列(空文字列を含む)と一致 ? 任意の1文字と一致 [ ] []内のいずれか1文字と一致 {..} {}内のいずれかの文字列と一致 **** 数値リテラル 123 整数 -123 整数(符合つき数) 1_234 整数(10進数は`_'を含むことができる) 123.45 浮動小数点数 1.2e-3 浮動小数点数 0xffff 16進整数 0377 8進整数 ?a 文字`a'のコード(97) ?\C-a コントロールaのコード(1) ?\M-a メタaのコード(225) ?\M-\C-a メタ-コントロールaのコード(129) \シンボル 識別子/変数名と一対一対応する整数．applyなどでメソッ ドを指定するのに使う． ?表現では全てのバックスラッシュ記法が有効である． *** コマンドの出力 Rubyではshのようにコマンドの実行結果を文字列リテラルのように使うことが できる．``で囲まれた文字列は，ダブルクォートと同様にバックスラッシュ記 法の解釈と変数展開が行なわれた後，コマンドとして実行され，その実行結果 が文字列として与えられる．コマンドは評価されるたびに実行される． *** 変数参照 Rubyの変数はスコープ(有効範囲)と寿命(有効期限)によって4種類に分類され， その種類は変数名の最初の一文字で決定される．通常の変数の2文字目以降は 英数時または`_'であるが，システム変数の一部は「`$'+1文字の記号」という 変数がある．変数名の長さに関して特別な制限はない． 変数のスコープに関わらず，初期化されていない変数を参照した時の値はnil である． **** グローバル変数 `$'で始まる変数のスコープはグローバルであり，プログラムのどこからでも 参照できる．その寿命はプログラムの寿命と等しい． **** インスタンス変数 `@'で始まる変数はインスタンス変数であり，そのクラスまたはサブクラスの メソッドから参照できる．スコープはメソッド内であり，その寿命はオブジェ クトの寿命に等しい． **** クラス名/モジュール名/ローカル変数 アルファベットまたは`_'で始まる変数は識別子とも呼ばれ，ローカル変数， クラス名またはモジュール名である． 初期状態では識別子はクラス/モジュール名とみなされるが(該当するクラスが 存在しない場合の値はnil)，代入式の左辺に現れた識別子は，そのスコープ内 ではローカル変数として見なされ，同名のクラスやモジュールは隠される．こ の意味で識別子への代入は宣言としての働きも持つ． Array # 配列クラス Array Array = 15 # 代入．以後Arrayはローカル変数 print Array, "\n" # `15'が出力される この宣言としての代入の解釈はコンパイル時に行なわれるため，識別子への代 入式が実際に実行されてもされなくても，以降のスコープ内ではその識別子は ローカル変数とみなされる． Array # 配列クラス Array if %FALSE Array = 15 # このコードは実行されないが， # 以降Arrayはローカル変数とみなされる． end print Array, "\n" # `nil'が出力される このルールは一見複雑だが，クラス/モジュール名とローカル変数名が重複し ない限り，未初期化のローカル変数の値はnilであると考えても差し支えはな い．Rubyの組み込みクラスは大文字のアルファベットで始まる名前がついて おり，ユーザもクラス/モジュール名には大文字で始まる識別子を，ローカル 変数名には小文字または`_'で始まる識別子を使うことを強く推奨する． ローカル変数のスコープも寿命もそのブロックの終りまで(トップレベルのロー カル変数はプログラムの終了まで)である． **** クラス変数(定数) `%'で始まる変数はクラス変数であり，そのクラスと全てのサブクラスのイン スタンスから参照できる．この変数への代入はトップレベル，すなわちメソッ ドが定義できるレベルでのみ可能である．この変数はクラス間で値が共有され， 一度代入するとメソッドからは値を変更することができないので，定数として 用いられる． **** 疑似変数 通常の変数以外に疑似変数と呼ばれる特殊な変数が4つある． self | 現在のメソッドの実行主体 nil | Nilクラスの唯一のインスタンス(偽を表す) __FILE__ | スクリプトのファイル名(文字列) __LINE__ | 現在の行番号(整数) これらの疑似変数は代入によってその値を変更することはできない．これらの 変数への代入は例外を発生させる． *** メッセージ式 オブジェクトにメッセージを送る基本的な構文がメッセージ式であり，その基 本形式は以下の通りである． 式1 '.' メソッド名 '(' 引数1... [',' '*' 引数n ]')' 式1を評価して得られるオブジェクトの，識別子で指定されるメソッドを呼び 出す．一番最後の引数が'*'に続く(単一の)式である場合，その式を評価した 結果(配列である必要がある)を展開して，引数として追加する． 引数が一つもない時には括弧を省略できる． メソッド名としては任意の識別子を用いることができる．変数名とは識別子の 名前空間が違うので重複しても構わない． メッセージ式で，レシーバがselfの場合，レシーバを省略して通常のプログラ ミング言語における関数のような形式でメソッドを呼び出すことができる．こ の場合引数が1つもない時でも括弧の省略はできない． クラス定義文の外で指定されたメソッドとクラスModuleのnoexportメソッドで 指定されたメソッドは関数的メソッドと呼ばれ，関数形式でしか呼び出すこと ができない． *** スーパークラスのメソッド呼び出し メッセージ式の特殊なケースとしてスーパークラスのメソッドの呼び出しがあ る．この形式はメソッドを再定義した時にスーパークラスの定義を利用するた めに使う． super 現在のメソッドに与えられた引数のままスーパクラスの同名のメソッドを呼び 出す． super'(' 引数... ')' 引数とともにスーパークラスの同名のメソッドを呼び出す．一番最後の引数が `*'に続く場合は通常のメソッド呼び出しと同様に渡される． *** 配列式/連想配列式 配列のオブジェクトを生成する式の形式は以下の形式である． '[' 式, ... ']' それぞれの式を評価した結果を含む配列を返す．要素数が0の空配列を生成す るためには空の配列式 '[' ']' を用いる． ** 連想配列式 連想配列とは任意のオブジェクトをキー(添字)として持てる配列である．Ruby では連想配列はSmalltalkの用語を借りてDict(辞書)とも呼ばれる．詳細はク ラスDictの項を参照されたい．連想配列を生成する連想配列式は以下の形式で ある． '{' 式 '=>' 式... '}' それぞれの式を評価した結果をキーと値とする連想配列オブジェクトを返す． 要素数が0の連想配列を生成するためには空の連想配列式 '{' '}' を用いる． *** 配列参照，配列代入 配列(連想配列を含む)の要素の参照は以下の形式で行なう． 式1 '[' 式2... ']' この形式は内部的に，式1に"[]"というメッセージを送ると解釈される．この 動作を疑似的なコードで記述すれば以下のようになる． 式1"[]"(式2...) 一方，配列要素の代入は 式1 '[' 式2... ']' '=' 式n という形式で行なわれ， 式1."[]="(式2...) という形式として解釈される． *** 演算子形式 プログラミングの利便のために一部のメソッド呼び出しと制御構造は演算子形 式をとる．Rubyには以下にあげる演算子がある．上のものほど結合順位が強く， 同じ列の演算子の結合順位は同じである． 強 -(unary) +(unary) ! ~ ** * / % + - << >> & | ^ > >= < <= <=> == != =~ !~ && || .. ..． :: =(代入) 自己代入(+=, -=, ..) and 弱 or ほとんどの演算式にはメソッド呼び出しとして解釈される(クラス毎に再定義 できる)が，一部再定義できない特殊なものがある．再定義できない特殊演算 子は &&(論理積), ||(論理和), =(代入), ...(範囲指定), and, or の6つである． 上であげた特殊演算子以外の演算子形式はメソッド呼び出しと見なされる． 単項演算子(+, -, !, ~)は 式1."演算子"() という形式に，それ以外の2項演算子は 式1."演算子"(式2) に解釈される． ** 代入 代入には変数に対する代入(真の代入)と，プログラムを簡単にするためのシン タックスシュガーとしての代入がある．真の代入は以下の形式である． 変数 '=' 式 これは式を評価し，変数の値として代入する．クラスやモジュールや疑似変数 には代入できない．クラスやモジュールの定義を変更するためにはclass文， module文を用いる．代入式は演算子形式をとっているが，メソッドではないの で再定義することはできない． シンタックスシュガーとしての代入式は以下のものがある． 配列要素への代入 式1'[' 式2... ' ]' '=' 式n 式1を評価して得られるオブジェクトに，式2から式nまでを引数として，"[]=" というメソッドを呼び出す． 属性代入 式1 '.' 識別子 '=' 式2 式1を評価して得られるオブジェクトに対して"識別子="というメソッドを，式 2を引数として呼び出す． 自己代入 式1 op= 式2 # 式1は代入可能でなければならない． この形式は内部的に「式1 = 式1 op 式2」と展開され，実行される．そのため 式1は2回評価されるので，副作用がある場合は予想しない結果を呼ぶ可能性が ある．自己代入形式はプログラマのタイプ数を減らす目的のためだけに存在す る形式である．opとして使える演算子は +, -, *, /, %, **, &, |, ^, <<, >> の11種類である．演算子と`='の間にスペースを空けてはいけない． *** 条件分岐式 式の値によって分岐する式は以下に示すif式，unless式，case式の複合文型が 3種類と演算子型が3種類ある．Rubyではnilが偽，それ以外が真と評価される． CやPerlなどとは異なり，0や ""(空文字列)は偽とは評価されないので気をつ けること． if式 if 式1 [then] 文1 [elsif 式2 [then] 文2 ]... [else 文n ] end 条件判断式．式1が真の場合に文1を評価する．それ以外の場合は文2を評価す る．Rubyのif式はelse ifでもelifでもなくelsifでifの連続を行なうことに注 意すること． unless式 unless 式1 [then] 文1 [else 文2 ] end 式1が偽(nil)を返すか，式2の評価中に例外が発生した場合に文1を評価する． それ以外の場合は文2を評価する． case式 case 式0 [when 式1 [, 式2]... [then] 文1 ]..． [else 文n ] end 条件分岐，CのswitchよりもPascalのcaseに似ている．breakで脱出することも 後ろの文に継続することもないので注意． 条件の一致は「式n =~ 式0]で行なわれる．つまり， case expr0 when expr1, expr2 stmt1 when expr3, expr4 stmt2 else stmt3 end は以下のif文とほぼ等価である． _tmp = expr0 if expr1 =~ _tmp || expr2 =~ _tmp stmt1 elsif expr3 =~ _tmp || expr4 =~ _tmp stmt2 else stmt3 end 演算子型 式1 '&&' 式2 式1 'and' 式2 式1を評価し，その値が真(nil以外)であれば，式2を評価する．`and'は優先順 位が低い別名である． 式1 '||' 式2 式1 'or 式2 式1を評価し，その値が偽であれば，式2を評価する．`or'は優先順位が低い別 名である． 式1 '...' 式2 式1が真になるまでは偽を返し，その後は式2が真を返すまでは真を返す．式2 が真になれば状態は偽に戻る *** 繰り返し式(単純型) ループを構成する式．これらの式の値は常にnilである．オブジェクトに合わ せたループを行なうためには次に述べるイテレータを用いる． while式 while 式 文 end 条件が真の間，文を繰り返し実行する． until式 until 式 文 end 式1 until 式2 式が偽(nil)を返すか，式の評価中に例外が発生する間，文を繰り返し実行す る． *** 条件式について if，unless，while，untilの条件判断部の式，および特殊演算子`&&', `||', `...'の両辺の式は条件式と呼ばれる．条件式では文字列と正規表現リテラル は式「$_=~リテラル」の省略であるとみなされる．更に演算子`...'の両辺で は整数定数が「$.==定数」の省略と解釈される．条件式に現れる`!'演算子の オペランドも条件式とみなされる． 注意: 演算子`!'は特殊演算子ではないので，再定義を行なう場合に気をつけ ること．条件式の中で ! 文字列リテラル ! 正規表現リテラル の形で呼び出されるメソッドの引数は，リテラルの表すオブジェクトではなく， 上記の比較の結果が与えられる．このため，原則的に`!'メソッドは再定義し ない方が良い． *** イテレータ(繰り返し子) イテレータとは制御構造(特にループ)の抽象化のために用いられるメソッドの 一種である．コードの断片(ブロックと呼ばれる)を指定してイテレータを呼び 出すと，イテレータは適当な値をセットしてブロックを評価する(おそらくは 複数回)．イテレータからのブロックの呼び出しはyield式を用いる(後述)． イテレータの呼び出しは以下の構文で行なわれる． イテレータとは制御構造(特にループ)の抽象化のために用いられるメソッドの 一種である．イテレータの呼び出しは以下の構文で行なわれる． 式 '{' 変数... '|' 文 '}' 「文」をブロックとして設定し，「式」のメソッドをイテレータとして評価す る．「式」のトップレベルのメソッドだけがイテレータとして呼び出され， レシーバを表す式や，引数の式はイテレータとしては呼び出されない．「式」 が複数の式を含む時，各々がイテレータとして順に呼ばれる． イテレータ内でyield文が実行されると，そこで指定された値がdo文で指定さ れた変数に代入され，ブロックが実行される．ブロックの実行が終了するとそ の値は yield文の値として返される．あるメソッドがイテレータとして呼び出 されたかどうかはメソッドiterator_p()の戻り値で知ることができる．中には Enumerableモジュールのgrepメソッドのようにイテレータとして呼ばれた時と 普通のメソッドとして呼ばれた時とで動作が異なるメソッドもある． オブジェクトの各要素に対して操作を行なうための形式も提供されている．形 式は以下の通り． for 変数.. in 式 文 end 式の各要素に対し文を実行する．これは以下の式と等価である． 式 '{' 変数 '|' 文 '}' よって式の値のオブジェクトがメソッドeachを持たない場合，forを実行する と例外が発生する． *** イテレータの中でのブロック呼び出し yield '(' [式 [',' 式...]]) yield イテレータの中でブロックの呼び出しを行なう．yieldを実行したメソッドが イテレータとして呼び出されていない時には例外が発生する．yield の値はブ ロックの戻り値である． *** 例外処理 処理中に予期しない事態が発生した時には例外が発生する．Rubyでは例外を途 中で捕捉して，再試行したり，後処理を行なったりすることができる． protect 文1 [resque 文2 ] [ensure 文3] end 文1を実行し，その実行中に例外が発生すればresque節で指定された文2を実行 する．更にensure節が存在する時はprotect文を終了する前に必ず(正常終了時 だけでなく，例外, return, break, continue, redoなどによる脱出でも)文3 を実行する． unless文，until文は条件を評価する時に例外が発生した場合，評価結果が偽 であると見なすので，暗黙の例外処理を行なっていることになる． *** グルーピング 式は括弧によってグルーピングすることができる． '(' 式 ')' 更に括弧を用いて，文(または文の並び)を式にすることもできる． '(' 文 ';' 文... ')' 文の並びの値は最後に評価した式の値である．つまりの値は最後に評価した文 の値になる． ** 文 Rubyプログラムを構成するもう一つの要素は文である．文には単純文，制御文， 宣言文がある．一般に文の値を用いることはないが，式として用いられる場合 もあるので，値を持つ．通常は文の値はnilである． *** 式 式は単純文である． *** 多重代入 同時に複数の変数に代入を行なうことができる．その形式は以下の通りである． 変数 ',' [変数 ',' ...] ['*' 変数]= 式 [, 式...] 右辺の式が一つしかない場合は，その値を配列として(必要ならばto_aメソッ ドで配列に変換して)，要素をそれぞれ変数に代入する．それ以外の場合には， それぞれの式の値が変数に代入される．左辺の変数の数と右辺の要素の数が合 わない時には足りない変数には nilが代入され，余った要素は無視される．多 重代入の最後の要素の前に`*'がある場合，残りの全て引数が配列として代入 される． foo, bar = [1, 2] # foo = 1; bar = 2 foo, bar = 1, 2 # foo = 1; bar = 2 foo, bar = 1 # foo = 1; bar = nil foo, bar, baz = 1, 2 # foo = 1; bar = 2; baz = nil foo, bar = 1, 2, 3 # foo = 1; bar = 2 foo,*bar = 1, 2, 3 # foo = 1; bar = [2, 3] 多重代入は単純文である．その値は(配列に変換された)右辺である． *** 制御文 制御の流れを変更する以下の文がある．これらは単純文である． return文 return [式[',' 式...]] 式の値を戻り値としてメソッドの実行を終了する．式が2つ以上与えられた時 には，それらを要素とする配列をメソッドの戻り値とする．式が一つもない場 合には nil が戻り値となる． ループ制御文 continue redo break 上記3つはループ中で使う． continueはもっとも内側のループの次の繰り返しを始める．redoはループ条件 のチェックを行なわず，現在の繰り返しをやり直す．break はループを脱出す る．Cと違い，breakはもっとも内側のループを脱出する作用だけを持ち，case を抜ける作用は持たない． retry文 retry protect文のresque節で使い，protect文を始めから実行する．例外処理を行なっ てから再試行するのに使う．resque節以外でretryが用いられた場合例外が発 生する． fail文 fail '(' [メッセージ] ')' fail [メッセージ] 例外を発生させる．メッセージが与えられた場合には発生したソースファイル 名，行番号をシステム変数`$@'に，メッセージを`$!'にセットする． yield文 yield 式 [',' 式...] 文としてyieldを用いることもできる．この場合は式を括弧で括る必要はない． *** メソッド呼び出し文 1つ以上の引数を持つメソッド呼び出す場合には曖昧さがなければ，引数を括 弧で括る必要はない．その形式は以下の通りである． 式 '.' メソッド名 引数1 ',' [引数2...]['*' 引数n] メソッド名 引数1 ',' [引数2...]['*' 引数n] super 引数1 ',' [引数2... ]['*' 引数n] 構文解析時に，式のように解釈できる場合は式としての解釈が優先される． foo bar+baz # メソッド呼び出しfoo(bar+baz) foo (bar)+baz # メソッド呼び出しfoo(bar) + bar foo 1 # メソッド呼び出しfoo(1) foo -1 # ローカル変数foo - 1 括弧のないメソッド呼び出し文は単純文である． *** 制御修飾子 単純文に制御修飾子を付加したものは文である(単純文ではない)．修飾子は以 下の4種類である． 単純文 if 式 単純文 unless 式 単純文 while 式 単純文 until 式 条件修飾子(if/unless)の式は先行する文に先だって評価される．動作も対応 する条件分岐式と同様である． 繰り返し修飾子(while/until)はまず先行する文を評価してから条件式を評価 するので，最低一度は文を実行することになる． *** クラス宣言文 クラスを定義する構文は以下の通りである． class クラス名 [':' スーパークラス名 ] 定義実体 end クラス名は任意の識別子である(大文字で始めることを推奨する)．クラス定義 のネストはできないので他の定義文内ではクラスを定義できない． *** モジュール定義文 モジュールを定義する構文は以下の通りである． module クラス名 定義実体 end モジュール名は大文字で始まる識別子である．クラス同様，モジュール定義も ネストできない． *** インクルード文 モジュールをインクルードすることによって，クラスまたはモジュールに機能 を追加できる．モジュールをインクルードした場合，そのモジュール(および そのモジュールが更にインクルードしているモジュール)の全てのメソッドを 受け継ぐ．別のいい方をすればインクルードは限定された多重継承といえる． 他のモジュールをインクルードする構文は以下の通りである． include モジュール名 [',' モジュール名...] 現在の定義中のクラスまたはモジュール(トップレベルではObjectクラス)に指 定したモジュールをインクルードする． *** メソッド定義文 通常(特異メソッドでない)メソッド定義の形式は以下の通りである．通常メソッ ド定義はネストできないので，メソッド定義文中ではメソッド定義文を再び呼 び出せない． def メソッド名 ['(' 引数 [',' 引数...][',' '*'引数 ] ')'] 定義実体 end メソッド名は識別子または文字列である．演算子の再定義をする時には文字列 で指定する．仮引数並びの最後に`*'がある場合，仮引数より多く与えられた 実引数は，最後の引数に配列として与えられる(足りない時にはエラー)． メソッドには関数的メソッドと通常メソッドがある．関数的メソッドは関数形 式でしか呼び出すことができず，よって該当するクラスとそのサブクラスのメ ソッドからしか呼び出すことができない．クラス定義文の外にあるdef文は関 数的メソッドを定義し，クラス定義文の中にあるdef文は通常のメソッドを定 義する．メソッドの可視性はModuleクラスのexport/noexportメソッドを使っ て変更する． ** 特異メソッド定義文 メソッド定義にはもう一つ特異メソッドの定義がある．特異メソッドとはある 特定のオブジェクトに固有のメソッドである．形式は以下の通りである． def 式 '.' メソッド名 ['(' 引数 [',' 引数...][',' '*'引数 ] ')'] 定義実体 end この形式は式の値であるオブジェクトに特異メソッドを定義する．式の値は (ビルトインクラスでない)通常オブジェクトか，クラスまたはモジュールであ る必要がある．通常メソッド定義とは異なり，特異メソッドはメソッド本体内 でもネストして定義することができる． 特異メソッドは通常は継承しえないが，例外としてクラスの特異メソッドはそ のサブクラスにも継承される．言い替えればクラスの特異メソッドは他のオブ ジェクト指向システムにおけるクラスメソッドの働きをする． *** メソッドの別名定義文 以下の形式でメソッドに別名をつけることができる． def メソッド名1 メソッド名2 別名を付けられたメソッドは，その時点でのメソッド定義を引き継ぎ，元のメ ソッドが再定義されても，古いメソッドが呼び出されたのと全く同じ働きをす る． *** メソッド定義取り消し文 メソッドの定義を取り消すためにはundefを用いる． undef メソッド名 識別子または文字列で指定したメソッドの定義を取り消す． defによる別名定義とundefによる定義取り消しを使うとクラスのインタフェー スをスーパークラスと独立に変更することができる．ただし，メソッドがself にメッセージを送っている場合にはよく注意しないと既存のメソッドが動作し なくなる可能性がある． ------------------------------------------------------- * Rubyの組み込み機能 Rubyプログラミングの基本はクラス，モジュールとそのメソッドの習得である． Rubyには処理系そのものに以下の機能が組み込まれている．ライブラリをロー ドすることによって機能は増えるが，それらに関してはそれぞれのライブラリ

require(file) fileをロードする．loadとの動作の違いはrequireはロードしたファ イルのフルパスを変数`$"'に覚えていて，既にロードしたファイルは 再ロードしない点である．実際にロードした時には%TRUE，既にロー ドされている時には%FALSEを返す． select(reads[, writes[, execpts[, timeout]]]) select(2)を実行する．reads/writes/execptsにはIO(またはそのサブ クラス)のインスタンスの配列を与える．timeoutはFixnum / Float / Timeのいずれかで指定する．戻り値はtimeoutが成立した場合には nil，そうでないときは3要素の配列を返し，その各要素が入力/出力/ 例外待ちのオブジェクトを要素として持つ． setenv(name, value) nameで指定される環境変数をvalueにセットする．$ENV[name]=value と同じ働きをする． sleep([sec]) sec秒だけプログラムの実行を停止する．secが省略された場合，プロ セスにSIGALRMが送られない限り，永久にスリープする．実際にスリー プした秒数を返す． sprintf(format, ...) format文字列をC言語のsprintfと同じように解釈し，引数を展開した 文字列を返す．メソッドformat()の別名． format指定子はC言語のsprintf()が受け付けるもの(ただし，Rubyに は unsignedがないので，%uは除く)に加えて, %b, %B, %O, %Xを使う ことができる．%bは数値の2進表示，%B, %O, %Xはそれぞれ2進，8進， 16進数の表示を行なうが，負の数の処理の際に2の補数表現ではなく， その絶対値表記の先頭に`-'をつけたものを表示する． srand([初期値]) 乱数の初期値を設定し，古い初期値を返す．初期値が省略された時に はtime(3)の返す値をデフォルトとする． sub(pattern, replace) システム変数`$_'の指す文字列に対して置換を行なう．文字列内で最 初にpatternにマッチする部分をreplaceに置き換える．subメソッド は`$_'の値を更新する．その他の詳細に関してはStringクラスのsub メソッドの解説を参照のこと． syscall(num, arg...) numで指定された番号のシステムコールを実行する．第2引数以降をシ ステムコールの引数として渡す．引数は文字列または整数でなければ ならない． system(command) コマンドを実行し，その終了ステータスを返す． trap(command, signal...) signalの割り込みがかかった時にcommandを実行する．signalはシグ ナル名かシグナルの番号．commandとして"SIG_IGN"または"IGNORE"を 指定した時にはそのシグナルを無視する(可能ならば)．"SIG_DFL"ま

最後のパターンマッチでマッチした文字列の前の文字列 $' 最後のパターンマッチでマッチした文字列の後に続く文字列 $+ 最後の検索パターンでマッチした最後の括弧 $1..$9 最後に成功したパターンマッチでn番目の括弧にマッチした 値が格納される．該当する括弧がなければnilが入っている． $~ 最後のマッチに関する情報．これをセットすると$&や$1..$9 の値が変化する． $= この変数の値がnilでない時，パターンマッチや文字列の比 較でアルファベットの大文字小文字を区別しない．デフォル トはnil(区別する)． $/ 入力レコードセパレータ．ファイルや文字列に対してeachを 行なう時の分割文字を指定する．$/に空文字列("")を指定す ると段落単位で入力を行ない，nilを指定すると全体を一度 に読み込む．$/には正規表現は使えない．デフォルトは "\n"． $\

引数(なければ標準入力)で構成される仮想ファイル．つまり gets()は$<.gets()と同じ意味である．$<.fileで現在読み込 み中のファイルオブジェクトが，$<.filenameでそのファイ ル名が得られる．(覚え方: `<'はシェルの入力元指定) $> printやprintfのデフォルトの出力先．初期値は$stdout．-i オプションを指定した場合には読み込み元と同じ名前のファ イル．(覚え方: `>'はシェルの出力先指定) $_ 最後にgets()などで読み込んだ文字列． $0 rubyスクリプトの名前．この変数に代入するとps(1)の出力 が変化する． $* rubyスクリプトに与えられた引数．ruby自身に対する引数は 取り除かれている． $$ 現在実行中のrubyプロセスのpid． $? 最後に実行した子プロセスのstatus． $: ファイルをロードする時に検索するディレクトリへのパスを 含む配列．起動時にはデフォルト値(コンパイル時に指定す る)に加えて，環境変数RUBYLIBの値とruby起動時の-Iオプショ ンで指定された値が追加される．(覚え方: コロンは環境変 数PATHの区切り文字である) $" 既にロードされたファイル名を含む配列．require()で同じ ファイルを2回ロードしないために用いられる．(覚え方: prevent files to be doubly quoted(loaded)) $ARGF $<の別名． $ARGV $*の別名． $DEBUG `-d'フラグの状態(真偽値)． $ENV 環境変数にアクセスする連想配列．文字列をキーとして与え ると対応する環境変数の値が得られる．環境変数が存在しな い場合はnilが返る． $FILENAME

それぞれ真偽値を表す．条件判断はnilを偽，それ以外の全ての値を 真として判断するため，%TRUEの値は代表的な真の値という以上の意 味を持たない．よって，あるメソッドの返値が真であるということと， それが%TRUEを返すということは厳密には同じではない(述語的に用い られるメソッドは大抵真の値として%TRUEを返すようにはなっている が)．つまり if some.method() then .. else .. end と if some.method() == %TRUE then .. else .. end は完全には同義ではない．%FALSEに関しては，このような問題は生じ ない． ** クラス/モジュール *** Array(クラス) 数字を添字とした配列のクラスである．生成は一般的には配列式``[...]''で 行なわれる． SuperClass: Object Included Modules: Enumerable Methods: self[nth] self[start..end] self[start, length] 配列の要素にアクセスする．最初の形式では配列のnth番目の要素を 返し，2番目の形式ではstart番目の要素からend番目の要素を含む部 分配列を返す．3番目の形式ではstart番目からlength個の要素を含む 部分配列を返す．

2番目，3番目の形式ではvalは配列でなければならない． 例: ary = [1, 2, 3, 4, 5] ary[0..2] = [0, 0] # 配列の内容は [0, 0, 4, 5] ary[1, 0] = [7] # 配列の内容は [0, 7, 0, 6, 5] self + other 配列の連結．selfとotherの両方の配列の内容を繋げた新しい配列を 返す． self *

配列の先頭の要素を取り除いて，それを返す． sort 配列の内容をソートする．イテレータとして呼び出された場合はブロッ クを評価した値で要素の大小を決定する．大きい時に正，等しい時に 0，小さき時に負．通常のメソッドとして呼び出された場合は各要素 を`<=>'で比較する． to_a 自分自身を返す．対称性のために用意されているメソッドであまり面 白くない． unshift(obj) objを配列の先頭に追加する． *** Bignum(クラス) 無限多倍長整数のクラス．演算の結果がこのFixnumの範囲内である場合には自 動的にクラスはFixnumに変換される．一般的にRubyプログラムではFixnumと Bignumの変換は暗黙のうちに行われるので，意識する必要は無い．Floatとの 混合に関しては，Bignumより Floatの方がgenericityが高いのにも関わらず， Bignumの方が，大きな値を表現できるので，変換時に桁落ちが生じる可能性が ある． SuperClass: Integer Methods: self + other self - other self * other self / other self % other self ** other

は自動的にBignum(無限多倍長整数)に拡張される． イテレータupto()，downto()，step()は繰り返しのために用いられ，一般に Rangeクラスを用いるより高速である． SuperClass: Integer Methods: self + other self - other self * other self / other self % other self ** other 算術演算．それぞれ和，差，積，商，剰余，冪乗を返す． ~ self self | other self & other self ^ other ビット演算．それぞれビット反転，論理和，論理積，排他的論理和を 返す． self << bits self >> bits シフト演算．それぞれbitsビットだけ左右にビットシフトを行なう． self .. max 範囲指定．self から

算術演算．それぞれ和，差，積，商，剰余，冪乗を返す． self == other self > other 比較演算． coerce(num) numをfloatに変換する．ただし現時点でFloatが理解できる他の数は FixnumとBignumだけである． to_f selfをそのまま返す． to_i selfを整数に変換した結果を返す． Single Methods: new(float) floatと同じ値を持つ新しいFloatオブジェクトを返す． *** GC(モジュール) Ruby組み込みのgarbage collectorの制御を行なうためのモジュール．このモ ジュールのメソッドをを用いることによって，一時的にGCを止めたり，GCの起 きるタイミングを制御したりできる． Methods: garbage_collect GCを開始する．「GC.start」と同義． Single Methods: disable GCを禁止する． enable GCを許可する． start GCを開始する． *** Glob(クラス) ワイルドカードのクラス．ワイルドカードのリテラルは<...>という形式であ る．正規表現とほぼ同じように使えるが，こちらは機能が少ない．ただし，ワ イルドカードの展開機能がある． SuperClass: Object Included Modules: Enumerable Methods: self =~ string ワイルドカードが文字列にマッチした場合には真を，しない場合は nilを返す． each ワイルドカードにマッチするファイル名を返すイテレータ． Single Methods: new(string) 文字列をワイルドカードに変換したオブジェクトを返す． *** Integer(クラス) 整数クラス．実際はその大きさによってFixnumとBignumいう二つのサブクラス で実現されている．Integerはそれらのスーパークラスとなる抽象クラスであ る．Rubyではほとんどの場合，FixnumとBignumの区別は必要なく，相互の変換 は自動的に行なわれる．整数をビット列だとみなす場合には，無限の長さをも つビット列と考えて構わない． SuperClass: Numeric Methods: self[idx] 整数のidxビット目がセットされていれば1，セットされていなければ 0を返す． chr その数をコードとする文字だけを含む1文字の文字列を返す．一般に 長さ1以上の文字列について，次の関係が常に成立する． str[0].chr == str[0,1] 整数が文字の範囲内(0..255)になければ例外が発生する． is_integer いつも真を返す． *** IO(クラス) 入出力のための基本クラス． SuperClass: Object Included Modules: Enumerable Methods: self << object objectを出力する．objectが文字列でない時にはメソッドto_sを用い て文字列に変換する．selfを戻り値とするので，C++のような`<<'の 連鎖を使える． 例: $stdout << 1 << " is a " << Fixnum << "\n" close 入出力ポートをクローズする．以後のこのオブジェクトに対する入出 力操作はエラーになる． each 一行ずつ読み込んでくるためのイテレータ．行の区切りはシステム変 数`$/'によって変更できる．読み込んだ文字列はシステム変数`$_'に もセットされる． each_byte() 一文字ずつ読み込んでくるためのイテレータ．文字は文字コードを表 すFixnumである． fileno to_i IOオブジェクトが使っているファイルディスクリプタ(Fixnum)を返す． flush バッファをフラッシュする． getc 一行読み込んで，読み込みに成功した時にはその文字列を返す．ファ イルの終りに到達した時にはnilを返す．カーネルメソッドgetc()は $stdin.getcと同じ意味である． gets

readlines ファイルを全て読み込んで各行を要素としてもつ配列を返す． sync 現在の出力同期モードを真偽値で返す．同期モードが真の時は出力関 数の呼出毎にバッファがフラッシュされる． sync=(newstate) 出力同期モードを設定する． sysread(length) stdioを経由せずにread(2)を用いて入力を行なう．入力されたデータ を含む文字列を返す．ファイルの終りに到達した時にはnilを返す． read(2)の性質により必ずlengthバイトの文字列が読み込まれるわけ ではない．gets()やgetc()などstdioを経由するメソッドと混用する ことはバッファリングの不整合などで思わぬ動作をすることがある． syswrite(str) stdioを経由せずに，write(2)を用いて出力を行なう．このメソッド はバッファリングなどstdioがしてくれることは一切行なわない． syswriteは実際に書き込んだバイト数を返す．print()やprintf()と syswrite()を混用するのは推奨できない． write(str) strを出力する．出力したバイト数を返す． *** Kernel(クラス) 全てのクラスの基底クラス．Ruby組み込みの全ての関数メソッドはこのクラス で定義されている．関数メソッドについては「関数」の項目を参照のこと． SuperClass: なし Methods: ! self 否定．Non-nilのオブジェクトの場合常に偽(nil)を返す．このメソッ ドはNilクラスでは再定義され真を返す． self == other equal(other) オブジェクトの一致判定．レシーバと引数の引数が一致する時，真を 返す．Kernelクラスの定義では双方のオブジェクトが同一の時真を返 す．"=="メソッドは各オブジェクトの性質に応じて再定義する必要が ある．"=="メソッドを再定義した時には，hashメソッドもそれに合わ せて再定義する必要がある． equal()メソッドは"=="メソッドの別名で，"=="を再定義した後でも オブジェクトの同一性判定を行なうために用いられる．よって equal()メソッドはサブクラスで再定義するべきではない． self != other "=="の否定．内部で"=="メソッドを呼び出しているので，こちらは再 定義する必要はない． self =~ other マッチ．デフォルトの動作は"=="と同じである．"=~"はcaseの比較に も用いられる． !~ "=~"の否定．内部で"=~"メソッドを呼び出しているので，こちらは再 定義する必要はない． self :: other selfとotherを要素とする長さ2の配列を返す．配列を生成するという 意味で [self, other]と同じ働きをするが，こちらの方がわずかに効 率が良い．この演算子は右結合であるので，a::b::c は (a::(b::c)) と解釈される． is_nil オブジェクトがnilであるかどうか．Kernelクラスの定義では真を返 す．Nilクラスで再定義されている． id 各オブジェクトに対して一意のFixnumを返す．が，Fixnumは自分自身を返 すので，idが一致しても同じオブジェクトであることは保証されない． つまり， obj1.id == obj2.id が成立しても，どちらかがFixnumであれば，obj1とobj2が同じである とは限らない．ただし，両方がFixnumでないことが保証できれば，2 つのオブジェクトが同一であることは確実である． hash オブジェクトのハッシュ値(Fixnum)を返す．Dictクラスでキーとなる オブジェクトを格納するのに用いられている.「A == B」が成立する 時は必ず「A.hash == B.hash」が成立する必要があるので，"=="を再 定義した時には必ずこちらもそれに合わせて再定義すること． *** Math(モジュール) 浮動小数点演算をサポートするクラス．Mathモジュールは同じ定義のメソッド と特異メソッドとの両方が定義されているので，特異メソッドを呼び出して使 う使い方と，クラスにインクルードして使う使い方との両方ができる． 例: pi = Math.atan2(1, 1) * 4; include Math pi2 = atan2(1, 1) Methods: Single Methods: atan2(x, y) π〜-πの範囲でX/Yのアークタンジェントを返す． cos(x) sin(x) tan(x) ラジアンで表されたxの三角関数の値を返す． exp(x) xの指数関数の値を返す． log(x) xの自然対数を返す． log10(x) xの常用対数を返す． sqrt(x) xの平方根を返す．xの値が負である時には例外を発生させる． cbrt(x) xの立方根を返す． *** Module(クラス) モジュールのクラス． SuperClass: Object Private Methods: attr(name[, public]) そのモジュールをインクルードしたクラスのインスタンスに対して nameで指定される属性を付加し，属性に対するアクセスメソッドを定 義する．attr("attr")はクラス定義に以下に示すコードを追加するの とほぼ同義である． def attr; @attr; end 省略可能な第2引数publicが与えられて，かつその値がnilでない時に はその属性には属性設定メソッドも用意され，外部から代入可能にな る．attr("attr", %TRUE)はクラス定義に以下のコードを追加するの とほぼ同義である． def attr; @attr; end def attr=(val); @attr = val; end 属性を構成するメソッドを再定義することによって，アクセス時の動 作を変更できる．例えば attr("test", %TRUE) def test=(val) print("test was ", @test, "\n") print("and now is ", @test = val, "\n") end のように設定時に属性の値を表示するようなことが可能である．attr はアクセスメソッドがすでに定義されている場合は，デフォルトのア クセスメソッドを定義しない． Methods: export(name[, name..]) nameで指定されたメソッドを通常形式で呼び出し可能にする．すでに 通常メソッドである場合には何もしない． to_s モジュールの文字列表現を返す．モジュールの場合の文字列表現はモ ジュール名である． unexport(name[, name..]) nameで指定されたメソッドを関数形式でだけ呼び出し可能にする．す でに関数メソッドである場合には何もしない． *** Nil(クラス) 偽を表すオブジェクトnilのクラス．偽変数(の値)nilはNilクラスの唯一のイ ンスタンスである． SuperClass: Kernel Methods: self + other otherが整数，浮動小数点数，文字列，配列である時，otherを返す． ! self 常に真を返す． is_nil 常に真を返す． *** Numeric(クラス) 数一般の性質を表す抽象クラス． SuperClass: Object Included Modules: Comparable Methods: + self オブジェクトselfそのものを返す - self 「0 - self」の値を返す．サブクラスでより効率的に再定義されるこ とが期待される． abs 絶対値を返す． divmod(other) 商と剰余の2要素の配列を返す． next 次の数を返す．次の数とはその数を越える最小の整数である． *** Object(クラス) 全ての通常クラスのスーパクラス．通常クラスのインスタンスの一般的な振舞 いを定義している．このクラスのサブクラスでないクラスはKernelとNilと， 組み込み関数を定義しているBuiltinだけである． SuperClass: Builtin Methods: is_member_of(class) オブジェクトselfがクラスclassのインスタンスである時，真を返す． is_kind_of(class) オブジェクトselfがクラスclassかそのサブクラスのインスタンスで ある時，真を返す． clone オブジェクトの複製を作る．インスタンスが即値であるFixnumクラス 以外のクラスの場合，「obj.equal(obj.clone)」は偽であるが，多く の場合「obj == obj.clone」は真である． to_s オブジェクトの文字列表現を返す．このメソッドは内部的にprint() やformat()メソッドで用いられている． to_a オブジェクトを配列に変換する．カーネルクラスで定義されているデ フォルトは，そのオブジェクト自身を含む1要素の配列を返す． *** Process(モジュール) プロセスに関する操作を行なうためのモジュール．Mathモジュールと同様に全 てのメソッドは特異メソッドとしても通常のメソッドとしても使える． Processはプロセスオブジェクトのクラスではなくて，プロセス操作のメソッ ドをまとめたものであることに注意すること． Methods: Single Methods: egid プロセスの現在の実効GIDを返す． egid=(gid) プロセスの現在の実効GIDをgidにセットする． euid プロセスの現在の実効UIDを返す． euid=(uid) プロセスの現在の実効UIDをuidにセットする． getpgrp([pid]) pidで指定されたプロセスが現在所属しているプロセスグループのid を返す．pidを省略した時とpidに0を与えた時は現在実行しているプ ロセスを対象にする． getpriority(which, who) whichとwhoで指定されるプロセス，プロセスグループ，ユーザの現在 の優先順位を返す．詳細はgetpriority(2)を参照．Processモジュー ルではwhichとして指定できる定数%PRIO_PROCESS，%PRIO_PGRP， %PRIO_USERが定義されている． gid プロセスの現在の実GIDを返す． gid= プロセスの現在の実GIDをgidにセットする. pid プロセスのプロセスIDを返す．これはシステム変数`$$'の値と同じで ある． ppid 親プロセスのプロセスのプロセスIDを返す．UNIXでは直接の親プロセ スが終了した場合，親プロセスのpidは1(initのpid)になる． setpgrp(pid, pgrp) pidで指定されたプロセスのプロセスグループをpgrpにする．pidに0 を与えると現在実行中のプロセスを対象にする． setpriority(which, who, prio) whichとwhoで指定されるプロセス，プロセスグループ，ユーザの現在 の優先順位をprioに設定する．詳細はsetpriority(2)を参照のこと． uid プロセスの現在の実UIDを返す． uid= プロセスの現在の実UIDをuidにセットする. *** Range(クラス) 範囲オブジェクトのクラス．範囲オブジェクトは`..'演算子によって生成され， 一般的には以下のような使い方をする for i in 1..5 ... end しかし，この場合は以下の方が速い. do 1.upto(5) ... end 範囲オブジェクトを生成する`..'演算子の両辺はComparableを含むクラスのイ ンスタンスであれば何でも構わない．範囲は始点と終点を含むことに注意する こと. SuperClass: Object Included Modules: Enumerable Methods: self =~ other selfがotherと同じクラスに対する範囲オブジェクトで，その範囲内 にotherがある時(start <= other <= end)，真を返す．これはcase文 で範囲指定する時に便利である．例えば case i when 1, 3..5 ... end case のようなコードを書くことができる． each 範囲内に存在するオブジェクトを与えるイテレータ．主にfor文のた めに用いられる． end 範囲の終点を返す start 範囲の始点を返す． *** Socket(クラス) SuperClass: BasicSocket ソケットそのものに対するシステムコールレベルのアクセスを提供するクラス． Perlのソケットに対するアクセスと同レベルの機能を提供している．このクラ スではソケットアドレスはpackされた文字列で，指定する．UDPソケットはこ のクラスを使って利用する． Methods: accept 新しい接続を受け付けて，新しい接続に対するソケットとアドレスの ペアを返す．accept(2)を参照． bind(addr) bind(2)と同じ働きをする．addrはpackされたソケットアドレス構造 体である． connect(addr) connect(2)と同じ働きをする．addrはpackされたソケットアドレス構 造体である． listen(backlog) listen(2)と同じ働きをする． recv(len[, flags]) ソケットからデータを受け取り，文字列として返す．lenは受け取る 最大の長さを指定する．flagsについてはrecv(2)を参照．flagsのデ フォルト値は0である． recvfrom(len[, flags]) recvと同様にソケットからデータを受け取るが，戻り値は文字列と相 手ソケットのアドレスのペアである．引数についてはrecvと同様． send(mesg, flags[, to]) ソケットを介してデータを送る．flagsに関してはsend(2)を参照の事． connectしていないソケットに対しては送り先であるtoを指定する必 要がある．実際に送ったデータの長さを返す． Single Methods: open(domain, type, protocol) new(domain, type, protocol) 新しいソケットを生成する．domain，type，protocolはインクルード ファイルで定義されている定数値で指定する．domainとtypeに関して は，文字列で指定できるが，すべてをカバーしている保証はない． socketpair(domain, type, protocol) ソケットのペアを生成し，2要素の配列として返す．引数の指定は openと同じである． *** Regexp(クラス) 正規表現のクラス．正規表現のリテラルは/.../という形式で表すが，動的に 生成するためには Regexp.new(文字列) とする．ただし，Stringクラスの`=~'を始めとして多くのメソッドは正規表現 の替わりに文字列が与えられた時には内部的に正規表現を生成するので，生成 コストを節約したいと思う時や，正規表現の大文字小文字の区別を明示的に指 定したい時など以外は明示的に生成したいと思うことは少ないはずだ． SuperClass: Object Methods: self =~ string 正規表現が文字列にマッチした場合，マッチした位置を返す．マッチ しない場合はnilを返す． ~ self 「$_ =~ self」と同義． Single Methods: complie(string[, casefold]) new(string[, casefold]) 文字列を正規表現に変換したオブジェクトを返す．省略可能な第2引 数が与えられた時には，生成される正規表現オブジェクトはシステム 変数`$='の値に関わらず，真の時は大文字小文字を無視し，偽の時は 区別する．設定されない場合はマッチを行なった時点のシステム変数 `$='の値によって区別するかしないかが決定される． *** BasicSocket(クラス) ソケットを表す抽象クラス．具体的なソケット操作はサブクラスで定義される． 例えばインターネットドメインの場合はTCPsocketを用いる． SuperClass: IO Methods: getopt(level, optname) ソケットのオプションを取得する．getsockopt(2)を参照のこと．取 得したオプションの内容を含む文字列を返す． getpeername 接続の相手先のソケットの情報を得る．パックされたsockaddr構造体 をベタにダンプした文字列が返される．getpeername(2)を参照のこと． getsockname ソケットの情報を得る．パックされたsockaddr構造体をベタにダンプ した文字列が返される．getsockname(2)を参照のこと． setopt(level, optname, optval) ソケットのオプションを設定する．setsockopt(2)を参照のこと． shutdown(how) ソケットの以降の接続を終了させる．howが0である時，以降の受信が， howが1である時は，以降の送信が拒否される．howが2の時には，それ 以降の送信，受信ともに拒否される．shutdown(2)を参照． *** String(クラス) 文字列クラス．Rubyの文字列はヌルターミネートではないので，バイナリデー タも扱える．従ってどちらかというと単なる文字列というよりバイト列である． その思想に基づいて，正規表現に関するメソッド以外は2byte系の文字を意識 していない．これは作者の手抜きではなく意図的にそうしているのである(信 じてくれ)． SuperClass: Object Included Modules: Comparable, Enumerable Methods: self + other 文字列の連結．連結された文字列を返す． self * times 文字列の繰り返し．例えば "x" * 4 == "xxxx" である． self == other self > other 文字列の比較．システム変数$=がnilでない時には大文字小文字を区 別せずに比較を行なう． self =~ other 文字列のマッチ．otherは正規表現か文字列．otherが文字列の場合に は動的に正規表現に変換される．マッチした場合はマッチした位置， しなかった場合はnilが返る． ~ self 「$_ =~ self」と同義． self[nth] self[beg..end] self[beg,len] 内容の取り出し．1番目の形式ではnthバイト目のデータをFixnumとし て返す．2番目の形式ではbegバイト目からendバイト目までの部分文 字列を返す(両端を含む)．3番目の形式ではbegバイト目からlenバイ ト分の部分文字列を返す． self[nth] = val self[beg..end] = val self[beg,len] = val 内容の更新．1番目の形式ではnthバイト目のデータをval (整数)に変 更する．2番目の形式はbegバイト目からendバイト目までの部分文字 列をvalとして与えられた文字列で置き換える．3番目の形式はbegバ イト目からlenバイト分の部分文字列をvalとして与えられた文字列で 置き換える． capitalize 文字列中の最初の文字を(それがアルファベットであれば)，大文字に 変換し，残る文字列中のアルファベットを小文字に置き換える． chop 文字列の最後のバイトを切り落とす．元の文字列を変更することに注 意すること． crypt(salt) crypt(3)を用いて暗号化した文字列を返す．saltは2バイト以上の長 さの任意の文字列である． delete(str) 文字列のうち，strに含まれる文字を削除する．文字列の指定はtrと 同様であり，a-bでaからbまでの範囲を，先頭の^で文字列の否定(含 まれてないものを指定)を意味する．元の文字列を変更することに注 意すること． downcase 文字列中のアルファベットを全て小文字に置き換えた文字列を返す． each 文字列から1行ずつ読み込んでくるイテレータ． each_byte 文字列のそれぞれのバイトについて繰り返すイテレータ． gsub(pattern, replace)

を返す．文字列長がwidthより長い場合は元の文字列を返し，切り詰 めない． next selfからendまで「次の」文字列を返す．次の文字列とは数字は数字 として，英文字は英文字として増加し，桁上がりの処理が行なわれた ものである． "aa".next => "ab" "99".next => "100" "a9".next => "b0" oct 文字列を8進数を表す文字列と解釈して，整数に変換する．8進数の 定義は/[0-7]+/であり，文字列の先頭からこのパターンにマッチする 部分を整数に変換する．この定義に全く当てはまらない文字列に対し ては0を返す．perlとは違って文字列が0xから始まっているからといっ て 16進数だと見なしてくれたりはしない．それらは先頭の0が8進数 と認識され，0を返す． reverse 文字列の各バイトを逆順に並べた文字列を返す．文字列が2バイトで 構成される文字を含んでいてもお構いなしにバイト単位で反転する． splitは2バイト文字を理解するので，2バイト文字を含む文字列を文 字単位に反転するには "全角文字列".split(//).reverse.join("") とすればよい． rindex(substr[, pos]) 文字列substrが最後に出現する位置を返す．posを与えるとその位置 で検索を終了する．見つからない時にはnilを返す．indexとの相違点 は1)文字列の末尾から検索する．2)substrとして正規表現を受け付け ない．の2点である． split([sep[, limit]]) 文字列をsepで指定されたパターンによって，フィールドに分割する． sepが省略された時のデフォルトはシステム変数`$;'の値が用いられ る．limitが指定された時には最大limit個のフィールドに分割する． split()は分割された文字列を含む配列を返す．sepで指定されたパター ンが空文字列とマッチする場合は文字列が1文字ずつに分割される． squeeze([str]) 文字列のうち，strに含まれる文字が連続していた場合，一文字に圧 縮する．strが省略された場合，すべての文字を対象とする．文字列 の指定はtrと同様であり，`a-b'でaからbまでの範囲を，先頭の`^'で 文字列の否定(含まれてないものを指定)を意味する．元の文字列を変 更することに注意すること． strip 文字列の前後の空白を取り除く． sub(pattern, replace) 文字列中でpatternにマッチする部分をreplaceに置き換える．置換文 字列replace中の&と\0はマッチした文字列に，\1..\9は n番目の括弧 の内容に置き換えられる．sub()はgsub()と異なり，最初のマッチだ けを置換する． sum([bits]) 文字列のbitsビットのチェックサムを得る．省略値は16である．ruby では以下のコードでSystem Vの`sum'プログラムと同じ値を得られる． while gets() sum += $_.sum end sum %= 65536 swapcase 文字列中のアルファベットのうち大文字を小文字に，小文字を大文字 に置き換える． to_f 文字列をFloatに変換する． to_i 文字列を10進数を表す文字列と解釈して，整数に変換する． toupper 文字列中のアルファベットを全て大文字に置き換えた文字列を返す． tr("a-z", "A-Z")より少し速い． tolower

りも短い時はreplace文字列の最後の文字が繰り返されていると見な す．search文字列の方が短い時には対応する文字のないreplace部は 単に無視される(BSDのtrの動作)． search文字列，replace文字列中に`a-b'という形式が現れた場合，そ のaからbまでの範囲の文字をASCIIの昇順で指定したことになる．ま た，search文字列の最初の文字が`^'である場合，続く文字列に*含ま れない*文字列が置換の対象になる． tr(1)の機能のうち，文字を削除する機能，連続する文字を圧縮する 機能は別のメソッドに分割されている．それらの機能については delete，squeezeを参照のこと． 簡便のため，str.tr(src,repl).squeeze(repl)に相当するメソッド tr_s(src,repl) が提供されている． unpack(template) 文字列をtemplate文字列にしたがってアンパックし，それらの要素を 含む配列を返す．template文字列はArrayクラスのpackメソッドとほ ぼ同様である． a ASCII文字列(後続するnull文字やスペースを残す) A ASCII文字列(後続するnull文字やスペースを削除) b ビットストリング(下位ビットから上位ビット) B ビットストリング(上位ビットから下位ビット) h 16進文字列(下位ニブルが先) H 16進文字列(上位ニブルが先) c char C unsigned char s sort S unsigned sort i int I unsigned int l long L unsigned int n ネットワークバイトオーダーのshort N ネットワークバイトオーダーのlong f 単精度浮動小数点数(機種依存) d 倍精度浮動小数点数(機種依存) x 1バイト読み飛ばす X 1バイト後退 @ 絶対位置への移動 rubyのunpackはperlと違ってチェックサムの計算機能がないことに注 意すること． upcase 文字列中のアルファベットを全て大文字に置き換えた文字列を返す． upto(end) selfから始まって，endまで「次の」文字列を順に与えるイテレータ． 次の文字列とはstr.nextで与えられる文字列である． このメソッドはRange:eachで用いられているので，以下のような処理 が可能である． for i in "a" .. "ba" print(i, "\n"); end これはa, b, c, .. aa, .. az, baまでを各行に出力する． 気を付けなければいけないのは，この終了判定は大小関係ではなく `=='で判定されているため，`..'演算子の左辺の値に続く文字列に右 辺の文字列が含まれていない，以下の例のような場合は無限ループに 陥ってしまう． for i in "0" .. "1a" print(i, "\n"); end 作者はこう書くことによって責任を逃れてようとしていると考える人 もいるかもしれない．その推測は正しい． Single Methods: new(string) stringと同じ内容を持つ新しい文字列を返す． *** Struct(クラス) 構造体クラス．複数のデータをまとめる時に用いられる(例: Time::times)． データをまとめる時には配列クラスが用いられることもあるが(例: select)， 構造体を使うべき時は以下のような場合である． (1) 要素の数が固定 要素の数が変動するものは構造体を使うのには向かない． (2) 要素の数が多い 人間が一度に容易に扱える概念の数は7つまでであるという仮説がある． この仮説に従えば，要素が4つ以上あるデータの場合は配列を用いた場 合，要素数*2(つまりオフセットとその意味)が7を越える．よって，そ のような場合には構造体を使った方が理解しやすいと思われる． (3) 同時に大量に生成されない 構造体は配列よりも若干生成コストが高いので，速度が問題になる場合 (例えば同時に大量に生成される場合など)は構造体の使用が適切でない 可能性がある． 各構造体にはメンバ名と同名の引数のないメソッドが定義される． 本ドキュメント内で，構造体を表現するためには以下の形式を使う． struct 構造体名 メンバ ..． end しかし，プログラム中でこの形式で構造体を生成するわけではない． SuperClass: Object Included Modules: Enumerable Methods: self[idx] idxが数の時はidx番目の要素を返す．idxが文字列の時はidxと同じ名 前のメンバの要素を返す． values 構造体のメンバの値を要素に持つ配列を返す．例えば以下のコードで 自分のpasswdエントリを出力することができる． print(Etc.getpwuid().values.join(":"), "\n") この出力は`grep "$USER" /etc/passwd'の出力と余分なフィールドい くつか(システムによって異なる)がある以外は同じである． Single Methods: new(name, member::value...) nameという名前を持つ構造体を生成する．memberは構造体のメンバを 表す文字列であり，valueはその値である．生成された構造体はメン バで指定された名前の特異メソッドが定義されていて，そのメソッド によってメンバの内容を得ることができる． *** TCPserver(クラス) TCP/IPストリーム型接続のサーバ側のソケットのクラス．このクラスによって 簡単にソケットを利用したサーバのプログラミングができる．例えばechoサー バは以下のようになる． gs = TCPserver.open(4444) socks = [gs] while %TRUE nsock = select(socks); if nsock == nil; continue end for s in nsock[0] if s == gs socks.push(s.accept) else if s.eof s.close socks.delete(s) else str = s.gets s.write(str) end end end end SuperClass: TCPsocket Methods: accept クライアントからの接続要求を受け付け，接続したTCPsocketのイン スタンスを返す． Single Methods: new([host, ]service) open([host, ]service) serviceは/etc/services(またはNIS)に登録されているサービス名か ポート番号で指定する．hostを指定した時は指定したホストからの接 続だけを受け付ける．省略時は全てのホストからの接続要求を受け付 ける． *** TCPsocket インターネットドメインのストリーム型ソケットのクラス．通常のIOクラスの サブクラスと同様の入出力ができる．このクラスによってソケットを用いたク ライアントを簡単に記述できる．ユーザの入力をそのままサーバに転送するプ ログラムは以下のようになる． s = TCPsocket("localhost", 4444) while gets() s.write($_) print(s.read) end SuperClass: BasicSocket Methods: addr ソケットの接続情報を表す配列を返す．その配列の各要素は第1要素 が文字列 "AF_INET"，第2要素がport番号，第3要素がホストを表す文 字列である． peeraddr 接続相手先ソケットの情報を表す配列を返す．その配列の各要素は addrメソッドが返す配列と同じである． Single Methods: open(host, service) new(host, service) hostで指定したホストのserviceで指定したポートと接続したソケッ トを返す．hostはホスト名，またはインターネットアドレスを示す文 字列，serviceは/etc/services(またはNIS)に登録されているサービ ス名かポート番号である． *** Time(クラス) 時間を表すクラス．大小比較などができる．Time.nowで現在の時間を得ること ができる．またファイルのタイムスタンプを得るメソッドの戻り値もこのクラ スのインスタンスである． SuperClass: Object Included Modules: Comparable Methods: self <=> other otherはTimeのインスタンスか整数．整数が与えられた場 合には1970年 1月 1日 00:00:00 GMTからの秒数であると して時刻との比較を行なう． asctime ctime to_s 時刻をdate(1)形式の文字列に変換する． gmtime タイムゾーンの修正を行なわないGMTでの時刻を得る．このメソッド を受けとったTimeクラスのインスタンスは，以後の時刻変換をGMTで 行なう．gmtimeは自分自身を返す． ロンドンの時刻を表示するには print(Time.now.gmtime, "\n") とすればよい． localtime タイムゾーンの修正を行なった時刻を得る(デフォルト)．localtime は自分自身を返す． to_i tv_sec 1970年 1月 1日 00:00:00 GMTから時刻までの秒数を整数で返す．時 刻のsecondの部分でもある． sec min hour mday year wday yday zone isdst 内部的に保持しているtm構造体の内容を返す．zone以外は整数を返す． zoneはタイムゾーンを表す文字列を返す．(cf localtime(3)) strftime(format) 時刻をformat文字列に従って文字列に変換した結果を返す．format 文字列として指定できるものは 以下の通りである． %A 曜日の名称(Sunday, Monday,...) %a 曜日の省略名(Sun, Mon,...) %B 月の名称(January, February,...) %b 月の省略名(Jan, Feb,...) %c 時刻表現(cf ctime(3)) %d 十進数での日(01-31) %H 24時間制の時(00-23) %I 12時間制の時(01-12) %j 年中の通算日(001-366) %M 分(00-59) %m 月を表す数字(01-12) %p 午前または午後(AM,PM) %S 秒(00-61) %U 週を表す数字．最初の日曜日が第1週の 始まり(00-53) %W 週を表す数字．最初の月曜日が第1週の 始まり(00-53) %w 曜日を表す数字．日曜日が0(0-6) %X 時刻(例: 15:01:06) %x 日付(例: Fri Jan 14 1994) %Y 西暦を表す数字 %y 西暦の下2桁(00-99) %Z タイムゾーン %% %自身 usec tv_usec 時刻のmicro secondの部分を返す． Single Methods: now 現在の時刻を表すTimeクラスのインスタンスを生成する． at(time) timeと同じ時刻を表すTimeクラスのインスタンスを生成する．timeは Timeクラスのインスタンスかあるいは数(整数/浮動小数点数)であり， 数の場合は1970年 1月 1日 00:00:00 GMTからの秒数であるとして時 刻を計算する． times 現在のプロセスとその子プロセスが消費したユーザ/システムCPUタイ ムの積算を構造体として返す(Structを参照)． struct tms utime # プロセスのユーザ時間 stime # プロセスのシステム時間 cutime # 子プロセスのユーザ時間 cstime # 子プロセスのシステム時間 end 時間の単位は秒であり，浮動小数点数で与えられる．詳細は times(3)を参照のこと． *** UNIXserver UNIXストリーム型接続のサーバ側のソケットのクラス． SuperClass: UNIXsocket Methods: accept クライアントからの接続要求を受け付け，接続したUNIXsocketのイン スタンスを返す． *** UNIXsocket UNIXドメインのストリーム型ソケットのクラス．通常のIOクラスのサブクラス と同様の入出力ができる． SuperClass: BasicSocket Methods: addr ソケットの接続情報を表す配列を返す．その配列の各要素は第1要素 が文字列 "AF_UNIX"，第2要素がpathである． path UNIXソケットのパスを返す． peeraddr 接続相手先ソケットの情報を表す配列を返す．その配列の各要素は addrメソッドが返す配列と同じである． Single Methods: open(path) new(path) pathで指定したパス名を用いて接続したソケットを返す． ------------------------------------------------------- Local variables: fill-column: 70 end: ./ruby-0.63/sprintf.c100644 150 1 16726 5674170244 13054 0ustar matzdaemon/************************************************ sprintf.c - $Author: matz $ $Date: 1994/12/06 09:30:23 $ created at: Fri Oct 15 10:39:26 JST 1993 Copyright (C) 1994 Yukihiro Matsumoto ************************************************/ #include "ruby.h" #include static void fmt_setup();

Use xmalloc instead of malloc. This implementation of the PWB library alloca() function, which is used to allocate space off the run-time stack so that it is automatically reclaimed upon procedure exit, was inspired by discussions with J. Q. Johnson of Cornell. It should work under any C implementation that uses an actual procedure stack (as opposed to a linked list of frames). There are some preprocessor constants that can be defined when compiling for your specific system, for improved efficiency; however, the defaults should be okay. The general concept of this implementation is to keep track of all alloca()-allocated blocks, and reclaim any that are found to be deeper in the stack than the current invocation. This heuristic does not reclaim storage as soon as it becomes invalid, but it will do so eventually. As a special case, alloca(0) reclaims storage without allocating any. It is a good idea to use alloca(0) in your main control loop, etc. to force garbage collection. */ #ifndef lint static char SCCSid[] = "@(#)alloca.c 1.1"; /* for the "what" utility */ #endif #include "config.h" #ifdef emacs #ifdef static /* actually, only want this if static is defined as "" -- this is for usg, in which emacs must undefine static in order to make unexec workable */ #ifndef STACK_DIRECTION you lose -- must know STACK_DIRECTION at compile-time #endif /* STACK_DIRECTION undefined */ #endif /* static */ #endif /* emacs */ #ifdef X3J11 typedef void *pointer; /* generic pointer type */ #else typedef char *pointer; /* generic pointer type */ #endif /* X3J11 */ #define NULL 0 /* null pointer constant */ extern void free(); extern pointer xmalloc(); /* Define STACK_DIRECTION if you know the direction of stack growth for your system; otherwise it will be automatically deduced at run-time.

When doing that it came to mind that your weeknumber() function compiles a little bit nicer in the following form: /* * firstweekday is 0 if starting in Sunday, non-zero if in Monday */ { return (timeptr->tm_yday - timeptr->tm_wday + (firstweekday ? (timeptr->tm_wday ? 8 : 1) : 7)) / 7; } How nicer it depends on a compiler, of course, but always a tiny bit.
