Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. ruby-1.3/ChangeLog100644 1750 1750 265523 6640404300 12412 0ustar matzmatzThu Dec 24 18:26:04 1998 Yukihiro Matsumoto * developpers' version 1.3 released.

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.netlab.co.jp/pub/lang/ruby/ * How to compile and install This is what you need to do to compile and install Ruby: 1. Run ./configure, which will generate config.h and Makefile. 2. Edit defines.h if you need. Probably this step will not need. 3. 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. 4. Run make. 5. 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). 6. 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. * Copying Ruby is copyrighted free software by Yukihiro Matsumoto .

In contrast, Ruby variables do not have static type and data themselves have types. So, data need to be converted across the languages. Data in Ruby represented C type `VALUE'. Each VALUE data have its data-type. To retrieve an C data from the VALUE, you need to: (1) Identify VALUE's data type (2) Convert VALUE into C data Converting to wrong data type may cause serious promblems. 1.1 Data-types Ruby interpreter has data-types as below: T_NIL nil T_OBJECT ordinaly object T_CLASS class T_MODULE module T_FLOAT floating point number T_STRING string T_REGEXP regular expression T_ARRAY array T_FIXNUM Fixnum(31bit integer) T_HASH assosiative array T_STRUCT (Ruby) structure T_BIGNUM multi precision integer T_TRUE true T_FALSE false T_DATA data Otherwise, there are several other types used internally: T_ICLASS T_MATCH T_VARMAP T_SCOPE T_NODE Most of the types are represented by C structures. 1.2 Check Data Type of the VALUE The macro TYPE() defined in ruby.h shows data-type of the VALUE. TYPE() returns the constant number T_XXXX described above. To handle data-types, the code will be like: switch (TYPE(obj)) { case T_FIXNUM: /* process Fixnum */ break; case T_STRING: /* process String */ break; case T_ARRAY: /* process Array */ break; default: /* raise exception */ Fail("not valid value"); break; } There is the data-type check function. void Check_Type(VALUE value, int type) It raises an exception, if the VALUE does not have the type specified. There are faster check-macros for fixnums and nil. FIXNUM_P(obj) NIL_P(obj) 1.3 Convert VALUE into C data The data for type T_NIL, T_FALSE, T_TRUE are nil, true, false respectively. They are singletons for the data type. The T_FIXNUM data is the 31bit length fixed integer (63bit length on some machines), which can be conver to the C integer by using FIX2INT() macro. There also be NUM2INT() which converts any Ruby numbers into C integer. The NUM2INT() macro includes type check, so the exception will be raised if conversion failed. Other data types have corresponding C structures, e.g. struct RArray for T_ARRAY etc. VALUE of the type which has corresponding structure can be cast to retrieve the pointer to the struct. The casting macro RXXXX for each data type like RARRAY(obj). see "ruby.h". For example, `RSTRING(size)->len' is the way to get the size of the Ruby String object. The allocated region can be accessed by `RSTRING(str)->ptr'. For arrays, `RARRAY(ary)->len' and `RARRAY(ary)->ptr' respectively. Notice: Do not change the value of the structure directly, unless you are responsible about the result. It will be the cause of interesting bugs. 1.4 Convert C data into VALUE VALUEの実際の構造は * FIXNUMの場合 1bit右シフトして，LSBを立てる． * その他のポインタの場合 そのままVALUEにキャストする． となっています．よって，LSBをチェックすればVALUEがFIXNUMかど うかわかるわけです(ポインタのLSBが立っていないことを仮定して いる)． ですから，FIXNUM以外のRubyのオブジェクトの構造体は単にVALUE にキャストするだけでVALUEに変換出来ます．ただし，任意の構造 体がVALUEにキャスト出来るわけではありません．キャストするの はRubyの知っている構造体(ruby.hで定義されているstruct RXxxx のもの)だけにしておいてください． FIXNUMに関しては変換マクロを経由する必要があります．Cの整数 からVALUEに変換するマクロは以下のものがあります．必要に応じ て使い分けてください． INT2FIX() もとの整数が31bit以内に収まる時 INT2NUM() 任意の整数からVALUEへ INT2NUM()は整数がFIXNUMの範囲に収まらない場合，Bignumに変換 してくれます(が，少し遅い)． 1.5 Manipulate Ruby data As I already told, it is not recommended to modify object's internal structure. To manipulate objects, use functions supplied by Ruby interpreter. Useful functions are listed below (not all): String funtions rb_str_new(char *ptr, int len) Creates a new Ruby string. rb_str_new2(char *ptr) Creates a new Ruby string from C string. This is equivalent to rb_str_new(ptr, strlen(ptr)). rb_str_cat(VALUE str, char *ptr, int len) Appends len bytes data from ptr to the Ruby string. Array functions rb_ary_new() Creates an array with no element. rb_ary_new2(int len) Creates an array with no element, with allocating internal buffer for len elements. rb_ary_new3(int n, ...) Creates an n-elements array from arguments. rb_ary_new4(int n, VALUE *elts) Creates an n-elements array from C array. rb_ary_push(VALUE ary, VALUE val) rb_ary_pop(VALUE ary) rb_ary_shift(VALUE ary) rb_ary_unshift(VALUE ary, VALUE val) rb_ary_entry(VALUE ary, int idx) Array operations. The first argument to each functions must be an array. They may dump core if other types given. 2. Extend Ruby with C 原理的にRubyで書けることはCでも書けます．RubyそのものがCで記 述されているんですから，当然といえば当然なんですけど．ここで はRubyの拡張に使うことが多いだろうと予測される機能を中心に紹 介します． 2.1 Add new features to Ruby Rubyで提供されている関数を使えばRubyインタプリタに新しい機能 を追加することができます．Rubyでは以下の機能を追加する関数が 提供されています． * Classes, Modules * Methods, Singleton Methods * Constants では順に紹介します． 2.1.1 Class/module definition To define class or module, use functions below: VALUE rb_define_class(char *name, VALUE super) VALUE rb_define_module(char *name) These functions return the newly created class ot module. You may want to save this reference into the variable to use later. 2.1.2 Method/singleton method definition To define methods or singleton methods, use functions below: void rb_define_method(VALUE class, char *name, VALUE (*func)(), int argc) void rb_define_singleton_method(VALUE object, char *name, VALUE (*func)(), int argc) The `argc' represents the number of the arguments to the C function, which must be less than 17. But I believe you don't need that much. :-) If `argc' is negative, it specifies calling sequence, not number of the arguments. If argc is -1, the function will be called like: VALUE func(int argc, VALUE *argv, VALUE obj) where argc is the actual number of arguments, argv is the C array of the arguments, and obj is the receiver. if argc is -2, the arguments are passed in Ruby array. The function will be called like: VALUE func(VALUE obj, VALUE args) where obj is the receiver, and args is the Ruby array containing actual arguments. There're two more functions to define method. One is to define private method: void rb_define_private_method(VALUE class, char *name, VALUE (*func)(), int argc) The other is to define module function, which is private AND singleton method of the module. For example, sqrt is the module function defined in Math module. It can be call in the form like: Math.sqrt(4) or include Math sqrt(4) To define module function void rb_define_module_function(VALUE module, char *name, VALUE (*func)(), int argc) Oh, in addition, function-like method, which is private method defined in Kernel module, can be defined using: void rb_define_global_function(char *name, VALUE (*func)(), int argc) 2.1.3 Constant definition We have 2 functions to define constants: void rb_define_const(VALUE class, char *name, VALUE val) void rb_define_global_const(char *name, VALUE val) The former is to define constant under specified class/module. The latter is to define global constant. 2.2 Use Ruby features from C There are several ways to invoke Ruby's features from C code. 2.2.1 Evaluate Ruby Program in String Easiest way to call Ruby's function from C program is to evaluate the string as Ruby program. This function will do the job. VALUE rb_eval_string(char *str) Evaluation is done under current context, thus current local variables of the innermost method (which is defined by Ruby) can be accessed. 2.2.2 ID or Symbol You can invoke methods directly, without parsing the string. First I need to explain about symbols (which data type is ID). ID is the integer number to represent Ruby's identifiers such as variable names. It can be accessed from Ruby in the form like: :Identifier You can get the symbol value from string within C code, by using rb_intern(char *name) In addition, the symbols for one character operators (e.g +) is the code for that character. 2.2.3 Invoke Ruby method from C To invoke methods directly, you can use the function below VALUE rb_funcall(VALUE recv, ID mid, int argc, ...) This function invokes the method of the recv, which name is specified by the symbol mid. 2.2.4 Accessing the variables and constants Cから関数を使って参照・更新できるのは，クラス定数，インスタ ンス変数です．大域変数は一部のものはCの大域変数としてアクセ スできます．ローカル変数を参照する方法は公開していません． The functions to access/modify instance variables are below: VALUE rb_ivar_get(VALUE obj, ID id) VALUE rb_ivar_set(VALUE obj, ID id, VALUE val) id must be the symbol, which can be retrieved by rb_intern(). To access the constants of the class/module: VALUE rb_const_get(VALUE obj, ID id) See 2.1.3 for defining new constant. 3. Informatin sharing between Ruby and C C言語とRubyの間で情報を共有する方法について解説します． 3.1 Ruby constant that Cから参照できるRubyの定数 Following Ruby constants can be referred from C. Qtrue Qfalse Boolean values. Qfalse is false in the C also (i.e. 0). Qnil Ruby nil in C scope. 3.2 Global variables shared between C and Ruby CとRubyで大域変数を使って情報を共有できます．共有できる大域 変数にはいくつかの種類があります．そのなかでもっとも良く使わ れると思われるのはrb_define_variable()です． void rb_define_variable(char *name, VALUE *var) この関数はRubyとCとで共有する大域変数を定義します．変数名が `$'で始まらない時には自動的に追加されます．この変数の値を変 更すると自動的にRubyの対応する変数の値も変わります． またRuby側からは更新できない変数もあります．このread onlyの 変数は以下の関数で定義します． void rb_define_readonly_variable(char *name, VALUE *var) これら変数の他にhookをつけた大域変数を定義できます．hook付き の大域変数は以下の関数を用いて定義します．hook付き大域変数の 値の参照や設定はhookで行う必要があります． void rb_define_hooked_variable(char *name, VALUE *var, VALUE (*getter)(), VALUE (*setter)()) この関数はCの関数によってhookのつけられた大域変数を定義しま す．変数が参照された時には関数getterが，変数に値がセットされ た時には関数setterが呼ばれる．hookを指定しない場合はgetterや setterに0を指定します． # getterもsetterも0ならばrb_define_variable()と同じになる． それから，Cの関数によって実現されるRubyの大域変数を定義する 関数があります． void rb_define_virtual_variable(char *name, VALUE (*getter)(), VALUE (*setter)()) この関数によって定義されたRubyの大域変数が参照された時には getterが，変数に値がセットされた時にはsetterが呼ばれます． The prototypes of the getter and setter functions are as following: (*getter)(ID id, void *data, struct global_entry* entry); (*setter)(VALUE val, ID id, void *data, struct global_entry* entry); 3.3 Encapsulate C data into Ruby object Cの世界で定義されたデータ(構造体)をRubyのオブジェクトとして 取り扱いたい場合がありえます．このような場合には，Dataという RubyオブジェクトにCの構造体(へのポインタ)をくるむことでRuby オブジェクトとして取り扱えるようになります． Dataオブジェクトを生成して構造体をRubyオブジェクトにカプセル 化するためには，以下のマクロを使います． Data_Wrap_Struct(class,mark,free,ptr) このマクロの戻り値は生成されたDataオブジェクトです． classはこのDataオブジェクトのクラスです．ptrはカプセル化する Cの構造体へのポインタです．markはこの構造体がRubyのオブジェ クトへの参照がある時に使う関数です．そのような参照を含まない 時には0を指定します． # そのような参照は勧められません． freeはこの構造体がもう不要になった時に呼ばれる関数です．この 関数がガーベージコレクタから呼ばれます． Cの構造体の割当とDataオブジェクトの生成を同時に行うマクロと して以下のものが提供されています． Data_Make_Struct(class, type, mark, free, sval) このマクロの戻り値は生成されたDataオブジェクトです． class, mark, freeはData_Wrap_Structと同じ働きをします．type は割り当てるC構造体の型です．割り当てられた構造体は変数sval に代入されます．この変数の型は (type*) である必要があります． Dataオブジェクトからポインタを取り出すのは以下のマクロを用い ます． Data_Get_Struct(obj, type, sval) Cの構造体へのポインタは変数svalに代入されます． これらのDataの使い方はちょっと分かりにくいので，後で説明する 例題を参照してください． 4．Example - Create dbm module ここまでの説明でとりあえず拡張ライブラリは作れるはずです． Rubyのextディレクトリにすでに含まれているdbmモジュールを例に して段階的に説明します． (1) make the directory % mkdir ext/dbm Make a directory for the extension library under ext directory. (2) create MANIFEST file % cd ext/dbm % touch MANIFEST There should be MANIFEST file in the directory for the extension library. Make empty file now. (3) design the library You need to design the library features, before making it. (4) write C code. 拡張ライブラリ本体となるC言語のソースを書きます．C言語のソー スがひとつの時には「モジュール名.c」を選ぶと良いでしょう．C 言語のソースが複数の場合には逆に「モジュール名.c」というファ イル名は避ける必要があります．オブジェクトファイルとモジュー ル生成時に中間的に生成される「モジュール名.o」というファイル とが衝突するからです． Rubyは拡張ライブラリをロードする時に「Init_モジュール名」と いう関数を自動的に実行します．dbmモジュールの場合「Init_dbm」 です．この関数の中でクラス，モジュール，メソッド，定数などの 定義を行います．dbm.cから一部引用します． -- Init_dbm() { /* define DBM class */ cDBM = rb_define_class("DBM", rb_cObject); /* DBM includes Enumerate module */ rb_include_module(cDBM, rb_mEnumerable); /* DBM has class method open(): arguments are received as C array */ rb_define_singleton_method(cDBM, "open", fdbm_s_open, -1); /* DBM instance method close(): no args */ rb_define_method(cDBM, "close", fdbm_close, 0); /* DBM instance method []: 1 argument */ rb_define_method(cDBM, "[]", fdbm_fetch, 1); : } -- DBMモジュールはdbmのデータと対応するオブジェクトになるはずで すから，Cの世界のdbmをRubyの世界に取り込む必要があります． dbm.cではData_Make_Structを以下のように使っています． -- struct dbmdata { int di_size; DBM *di_dbm; }; obj = Data_Make_Struct(class,struct dbmdata,0,free_dbm,dbmp); -- ここではdbmstruct構造体へのポインタをDataにカプセル化してい ます．DBM*を直接カプセル化しないのはclose()した時の処理を考 えてのことです． Dataオブジェクトからdbmstruct構造体のポインタを取り出すため に以下のマクロを使っています． -- #define GetDBM(obj, dbmp) {\ Data_Get_Struct(obj, struct dbmdata, dbmp);\ if (dbmp->di_dbm == 0) closed_dbm();\ } -- ちょっと複雑なマクロですが，要するにdbmdata構造体のポインタ の取り出しと，closeされているかどうかのチェックをまとめてい るだけです． DBMクラスにはたくさんメソッドがありますが，分類すると3種類の 引数の受け方があります．ひとつは引数の数が固定のもので，例と してはdeleteメソッドがあります．deleteメソッドを実装している fdbm_delete()はこのようになっています． -- static VALUE fdbm_delete(obj, keystr) VALUE obj, keystr; { : } -- 引数の数が固定のタイプは第1引数がself，第2引数以降がメソッド の引数となります． 引数の数が不定のものはCの配列で受けるものとRubyの配列で受け るものとがあります．dbmモジュールの中で，Cの配列で受けるもの はDBMのクラスメソッドであるopen()です．これを実装している関 数fdbm_s_open()はこうなっています． -- static VALUE fdbm_s_open(argc, argv, class) int argc; VALUE *argv; VALUE class; { : if (rb_scan_args(argc, argv, "11", &file, &vmode) == 1) { mode = 0666; /* default value */ } : } -- このタイプの関数は第1引数が与えられた引数の数，第2引数が与え られた引数の入っている配列になります．selfは第3引数として与 えられます． この配列で与えられた引数を解析するための関数がopen()でも使わ れているrb_scan_args()です．第3引数に指定したフォーマットに 従い，第4変数以降に指定した変数に値を代入してくれます．この フォーマットは，第1文字目が省略できない引数の数，第2文字目が 省略できる引数の数，第3文字目が対応する相手が無いあまりの引 数があるかどうかを示す"*"です．2文字目と3文字目は省略できま す．dbm.cの例では，フォーマットは"11"ですから，引数は最低1つ で，2つまで許されるという意味になります．省略されている時の 変数の値はnil(C言語のレベルではQnil)になります． Rubyの配列で引数を受け取るものはindexesがあります．実装はこ うです． -- static VALUE fdbm_indexes(obj, args) VALUE obj; struct RArray *args; { : } -- 第1引数はself，第2引数はRubyの配列です．ここではキャストを減 らすため struct RArray* で受けていますが，VALUEでも同じこと です． ** Notice GC should know about global variables which refers Ruby's objects, but not exported to the Ruby world. You need to protect them by void rb_global_variable(VALUE *var) (5) prepare extconf.rb もしディレクトリに「extconf.rb」というファイルが存在すれば， make時に実行されます．なければ適当にMakefileが生成されます． extconf.rbはモジュールのコンパイルに必要な条件のチェックなど を行うことが目的です．extconf.rbの中では以下のRuby関数を使う ことが出来ます． have_library(lib, func): ライブラリの存在チェック have_func(func): 関数の存在チェック have_header(header): ヘッダファイルの存在チェック create_makefile(target): Makefileの生成 以下の変数を使うことができます． $CFLAGS: コンパイル時に追加的に指定するフラグ(-Iなど) $LDFLAGS: リンク時に追加的に指定するフラグ(-Lなど) モジュールをコンパイルする条件が揃わなず，そのモジュールはコ ンパイルしない時にはcreate_makefileを呼ばなければMakefileは 生成されず，コンパイルも行われません． (6) prepare depend (optional) もし，ディレクトリにdependというファイルが存在すれば， Makefileが依存関係をチェックしてくれます． % gcc -MM *.c > depend などで作ることが出来ます．あって損は無いでしょう． (7) MANIFESTファイルにファイル名を入れる % ls > MANIFEST % vi MANIFEST *.o, *~など不必要なファイル以外はMANIFESTに追加しておきます． make時にはMANIFESTの内容は参照しませんので，空のままでも問題 は起きませんが，パッケージングの時に参照することがあるのと， 必要なファイルを区別できるので，用意しておいた方が良いでしょ う． (8) make Rubyのディレクトリでmakeを実行するとMakefileを生成からmake， 必要によってはそのモジュールのRubyへのリンクまで自動的に実行 してくれます．extconf.rbを書き換えるなどしてMakefileの再生成 が必要な時はまたRubyディレクトリでmakeしてください． (9) debug You may need to rb_debug the module. The modules can be linked statically by adding directory name in the ext/Setup file, so that you can inspect the module by the debugger. (10) done, now you have the extension library 後はこっそり使うなり，広く公開するなり，売るなり，ご自由にお 使いください．Rubyの作者は拡張ライブラリに関して一切の権利を 主張しません． Appendix A. Rubyのソースコードの分類 Rubyのソースはいくつかに分類することが出来ます．このうちクラ スライブラリの部分は基本的に拡張ライブラリと同じ作り方になっ ています．これらのソースは今までの説明でほとんど理解できると 思います． ruby language core class.c error.c eval.c gc.c object.c parse.y variable.c utility functions dln.c fnmatch.c glob.c regex.c st.c util.c ruby interpreter implementation dmyext.c inits.c main.c ruby.c version.c class library array.c bignum.c compar.c dir.c enum.c file.c hash.c io.c math.c numeric.c pack.c process.c random.c range.c re.c signal.c sprintf.c string.c struct.c time.c Appendix B. 拡張用関数リファレンス C言語からRubyの機能を利用するAPIは以下の通りである． ** 型 VALUE Rubyオブジェクトを表現する型．必要に応じてキャストして用いる． 組み込み型を表現するCの型はruby.hに記述してあるRで始まる構造 体である．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． ** Variables and constants Qnil const: nil object Qtrue const: Qtrue object(default true value) Qfalse const: Qfalse object ** Cデータのカプセル化 Data_Wrap_Struct(VALUE class, void (*mark)(), void (*free)(), void *sval) Cの任意のポインタをカプセル化したRubyオブジェクトを返す．こ のポインタがRubyからアクセスされなくなった時，freeで指定した 関数が呼ばれる．また，このポインタの指すデータが他のRubyオブ ジェクトを指している場合，markに指定する関数でマークする必要 がある． Data_Make_Struct(class, type, mark, free, sval) type型のメモリをmallocし，変数svalに代入した後，それをカプセ ル化したデータを返すマクロ． Data_Get_Struct(data, type, sval) dataからtype型のポインタを取り出し変数svalに代入するマクロ． ** 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_class_under(VALUE module, char *name, VALUE super) superのサブクラスとして新しいRubyクラスを定義し，moduleの定 数として定義する． VALUE rb_define_module(char *name) 新しいRubyモジュールを定義する． VALUE rb_define_module_under(VALUE module, char *name, VALUE super) 新しいRubyモジュールを定義し，moduleの定数として定義する． 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)． void rb_extend_object(VALUE object, VALUE module) オブジェクトをモジュール(で定義されているメソッド)で拡張する． ** Defining Global Variables void rb_define_variable(char *name, VALUE *var) Defines a global variable which is shared between C and Ruby. If name contains the character which is not allowed to be part of the symbol, it can't be seen from Ruby programs. void rb_define_readonly_variable(char *name, VALUE *var) Defines a read-only global variable. Works just like rb_define_variable(), except defined variable is read-only. void rb_define_virtual_variable(char *name, VALUE (*getter)(), VALUE (*setter)()) Defines a virtual variable, whose behavior is defined by pair of C functions. The getter function is called when the variable is referred. The setter function is called when the value is set to the variable. The prototype for getter/setter functions are: VALUE getter(ID id) void setter(VALUE val, ID id) The getter function must return the value for the access. void rb_define_hooked_variable(char *name, VALUE *var, VALUE (*getter)(), VALUE (*setter)()) Defines hooked variable. It's virtual variable with C variable. The getter is called as VALUE getter(ID id, VALUE *var) returning new value. The setter is called as void setter(VALUE val, ID id, VALUE *var) GC requires to mark the C global variables which hold Ruby values. void rb_global_variable(VALUE *var) Tells GC to protect these variables. ** Constant Definition void rb_define_const(VALUE klass, char *name, VALUE val) Defines a new constant under the class/module. void rb_define_global_const(char *name, VALUE val) Defines global contant. This is just work as rb_define_const(cKernal, name, val) ** Method Definition 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(第3引数はself)．argcが-2の時, 第1引 数がself, 第2引数が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_private_method(VALUE class, char *name, VALUE (*func)(), int argc) privateメソッドを定義する．引数はrb_define_method()と同じ． rb_define_singleton_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(int atgc, VALUE *argv, char *fmt, ...) argc,argv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．必須引数が一つもない場合は0を指定する．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． VALUE rb_funcall2(VALUE recv, ID mid, int argc, VALUE *argv) メソッド呼び出し．引数をargc,argv形式で渡す． VALUE rb_eval_string(char *str) 文字列をRubyとスクリプトしてコンパイル・実行する． 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, 祖先を遡って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「隠れた」インスタ ンス変数になる． 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)(), void *arg1, VALUE (*func2)(), void *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_rescue(VALUE (*func1)(), void *arg1, VALUE (*func2)(), void *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)(), void *arg1, void (*func2)(), void *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 rb_warning(char *fmt, ...) rb_verbose時に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 rb_raise(rb_eRuntimeError, char *fmt, ...) 例外を発生させる．引数はprintf()と同じ． void rb_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 rb_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． ** Initialize and Starts the Interpreter The embedding API are below (not needed for extension libraries): void ruby_init(int argc, char **argv, char **envp) Initializes the interpreter. void ruby_run() Starts execution of the interpreter. void ruby_script(char *name) Specifies the name of the script ($0). Appendix B. Functions Available in extconf.rb extconf.rbの中では利用可能なコンパイル条件チェックの関数は以 下の通りである． have_library(lib, func) Checks whether library which contains specified function exists. Returns true if the library exists. have_func(func) Checks whether func exists. Returns true if the function exists. To check functions in the additional library, you need to check that library first using have_library(). have_header(header) Checks for the header files. Returns true if the header file exists. create_makefile(target) Generates the Makefile for the extension library. If you don't invoke this method, the compilation will not be done. /* * Local variables: * fill-column: 60 * end: */ ruby-1.3/README.EXT.jp100644 1750 1750 74556 6635660624 12574 0ustar matzmatz.\" README.EXT - -*- Text -*- created at: Mon Aug 7 16:45:54 JST 1995 Rubyの拡張ライブラリの作り方を説明します． 1．基礎知識 Cの変数には型があり，データには型がありません．ですから，た とえばポインタをintの変数に代入すると，その値は整数として取 り扱われます．逆にRubyの変数には型がなく，データに型がありま す．この違いのため，CとRubyは相互に変換しなければ，お互いの データをアクセスできません． RubyのデータはVALUEというCの型で表現されます．VALUE型のデー タはそのデータタイプを自分で知っています．このデータタイプと いうのはデータ(オブジェクト)の実際の構造を意味していて，Ruby のクラスとはまた違ったものです． VALUEからCにとって意味のあるデータを取り出すためには (1) VALUEのデータタイプを知る (2) VALUEをCのデータに変換する の両方が必要です．(1)を忘れると間違ったデータの変換が行われ て，最悪プログラムがcore dumpします． 1.1 データタイプ Rubyにはユーザが使う可能性のある以下のタイプがあります． T_NIL nil T_OBJECT 通常のオブジェクト T_CLASS クラス T_MODULE モジュール T_FLOAT 浮動小数点数 T_STRING 文字列 T_REGEXP 正規表現 T_ARRAY 配列 T_FIXNUM Fixnum(31bit長整数) T_HASH 連想配列 T_STRUCT (Rubyの)構造体 T_BIGNUM 多倍長整数 T_FILE 入出力 T_TRUE 真 T_FALSE 偽 T_DATA データ その他に内部で利用されている以下のタイプがあります． T_ICLASS T_MATCH T_VARMAP T_SCOPE T_NODE ほとんどのタイプはCの構造体で実装されています． 1.2 VALUEのデータタイプをチェックする ruby.hではTYPE()というマクロが定義されていて，VALUEのデータ タイプを知ることが出来ます．TYPE()マクロは上で紹介したT_XXXX の形式の定数を返します．VALUEのデータタイプに応じて処理する 場合には，TYPE()の値で分岐することになります． switch (TYPE(obj)) { case T_FIXNUM: /* FIXNUMの処理 */ break; case T_STRING: /* 文字列の処理 */ break; case T_ARRAY: /* 配列の処理 */ break; default: /* 例外を発生させる */ TypeError("not valid value"); break; } それとデータタイプをチェックして，正しくなければ例外を発生す る関数が用意されています． void Check_Type(VALUE value, int type) この関数はvalueがtypeで無ければ，例外を発生させます．引数と して与えられたVALUEのデータタイプが正しいかどうかチェックす るためには，この関数を使います． FIXNUMとNILに関してはより高速な判別マクロが用意されています． FIXNUM_P(obj) NIL_P(obj) 1.3 VALUEをCのデータに変換する データタイプがT_NIL, T_FALSE, T_TRUEである時，データはそれぞ れnil, false, trueです．このデータタイプのオブジェクトはひと つずつしか存在しません． データタイプがT_FIXNUMの時，これは31bitのサイズを持つ整数で す．FIXNUMをCの整数に変換するためにはマクロ「FIX2INT()」を使 います．それから，FIXNUMに限らずRubyのデータを整数に変換する 「NUM2INT()」というマクロがあります．このマクロはデータタイ プのチェック無しで使えます(整数に変換できない場合には例外が 発生する)． 同様にチェック無しで使える変換マクロはdoubleを取り出す 「NUM2DBL()」とchar*を取り出す「STR2CSTR()」があります． それ以外のデータタイプは対応するCの構造体があります．対応す る構造体のあるVALUEはそのままキャスト(型変換)すれば構造体の ポインタに変換できます． 構造体は「struct RXxxxx」という名前でruby.hで定義されていま す．例えば文字列は「struct RString」です．実際に使う可能性が あるのは文字列と配列くらいだと思います． ruby.hでは構造体へキャストするマクロも「RXXXXX()」(全部大文 字にしたもの)という名前で提供されています(例: RSTRING())． 例えば，文字列strの長さを得るためには「RSTRING(str)->len」と し，文字列strをchar*として得るためには「RSTRING(str)->ptr」 とします．配列の場合には，それぞれ「RARRAY(ary)->len」， 「RARRAY(ary)->ptr」となります． Rubyの構造体を直接アクセスする時に気をつけなければならないこ とは，配列や文字列の構造体の中身は参照するだけで，直接変更し ないことです．直接変更した場合，オブジェクトの内容の整合性が とれなくなって，思わぬバグの原因になります． 1.4 CのデータをVALUEに変換する VALUEの実際の構造は * FIXNUMの場合 1bit右シフトして，LSBを立てる． * その他のポインタの場合 そのままVALUEにキャストする． となっています．よって，LSBをチェックすればVALUEがFIXNUMかど うかわかるわけです(ポインタのLSBが立っていないことを仮定して いる)． ですから，FIXNUM以外のRubyのオブジェクトの構造体は単にVALUE にキャストするだけでVALUEに変換出来ます．ただし，任意の構造 体がVALUEにキャスト出来るわけではありません．キャストするの はRubyの知っている構造体(ruby.hで定義されているstruct RXxxx のもの)だけです． FIXNUMに関しては変換マクロを経由する必要があります．Cの整数 からVALUEに変換するマクロは以下のものがあります．必要に応じ て使い分けてください． INT2FIX() もとの整数が31bit以内に収まる自信がある時 INT2NUM() 任意の整数からVALUEへ INT2NUM()は整数がFIXNUMの範囲に収まらない場合，Bignumに変換 してくれます(が，少し遅い)． 1.5 Rubyのデータを操作する 先程も述べた通り，Rubyの構造体をアクセスする時に内容の更新を 行うことは勧められません．で，Rubyのデータを操作する時には Rubyが用意している関数を用いてください． ここではもっとも使われるであろう文字列と配列の生成/操作を行 い関数をあげます(全部ではないです)． 文字列に対する関数 rb_str_new(char *ptr, int len) 新しいRubyの文字列を生成する． rb_str_new2(char *ptr) Cの文字列からRubyの文字列を生成する．この関数の機能は rb_str_new(ptr, strlen(ptr))と同等である． rb_str_cat(VALUE str, char *ptr, int len) Rubyの文字列strにlenバイトの文字列ptrを追加する． 配列に対する関数 rb_ary_new() 要素が0の配列を生成する． rb_ary_new2(int len) 要素が0の配列を生成する．len要素分の領域をあらかじめ割り 当てておく． rb_ary_new3(int n, ...) 引数で指定したn要素を含む配列を生成する． rb_ary_new4(int n, VALUE *elts) 配列で与えたn要素の配列を生成する． rb_ary_push(VALUE ary, VALUE val) rb_ary_pop(VALUE ary) rb_ary_shift(VALUE ary) rb_ary_unshift(VALUE ary, VALUE val) rb_ary_entry(VALUE ary, int idx) Arrayの同名のメソッドと同じ働きをする関数．第1引数は必ず 配列でなければならない． 2．Rubyの機能を使う 原理的にRubyで書けることはCでも書けます．RubyそのものがCで記 述されているんですから，当然といえば当然なんですけど．ここで はRubyの拡張に使うことが多いだろうと予測される機能を中心に紹 介します． 2.1 Rubyに機能を追加する Rubyで提供されている関数を使えばRubyインタプリタに新しい機能 を追加することができます．Rubyでは以下の機能を追加する関数が 提供されています． * クラス，モジュール * メソッド，特異メソッドなど * 定数 では順に紹介します． 2.1.1 クラス/モジュール定義 クラスやモジュールを定義するためには，以下の関数を使います． VALUE rb_define_class(char *name, VALUE super) VALUE rb_define_module(char *name) これらの関数は新しく定義されたクラスやモジュールを返します． メソッドや定数の定義にこれらの値が必要なので，ほとんどの場合 は戻り値を変数に格納しておく必要があるでしょう． クラスやモジュールを他のクラスの内部にネストして定義する時に は以下の関数を使います． VALUE rb_define_class(VALUE outer, char *name, VALUE super) VALUE rb_define_module(VALUE outer, char *name) 2.1.2 メソッド/特異メソッド定義 メソッドや特異メソッドを定義するには以下の関数を使います． void rb_define_method(VALUE class, char *name, VALUE (*func)(), int argc) void rb_define_singleton_method(VALUE object, char *name, VALUE (*func)(), int argc) 念のため説明すると「特異メソッド」とは，その特定のオブジェク トに対してだけ有効なメソッドです．RubyではよくSmalltalkにお けるクラスメソッドとして，クラスに対する特異メソッドが使われ ます． これらの関数の argcという引数はCの関数へ渡される引数の数(と 形式)を決めます．argcが正の時は関数に引き渡す引数の数を意味 します．16個以上の引数は使えません(が，要りませんよね，そん なに)．実際の関数には先頭の引数としてselfが与えられますので， 指定した数より1多い引数を持つことになります． argcが負の時は引数の数ではなく，形式を指定したことになります． argcが-1の時は引数を配列に入れて渡されます．argcが-2の時は引 数はRubyの配列として渡されます． メソッドを定義する関数はもう二つあります．ひとつはprivateメ ソッドを定義する関数で，引数はrb_define_method()と同じです． void rb_define_private_method(VALUE class, char *name, VALUE (*func)(), int argc) privateメソッドとは関数形式でしか呼び出すことの出来ないメソッ ドです． もうひとつはモジュール関数を定義するものです．モジュール関数 とはモジュールの特異メソッドであり，同時にprivateメソッドで もあるものです．例をあげるとMathモジュールのsqrt()などがあげ られます．このメソッドは Math.sqrt(4) という形式でも include Math sqrt(4) という形式でも使えます．モジュール関数を定義する関数は以下の 通りです． void rb_define_module_function(VALUE module, char *name, VALUE (*func)(), int argc) 関数的メソッド(Kernelモジュールのprivate method)を定義するた めの関数は以下の通りです． void rb_define_global_function(char *name, VALUE (*func)(), int argc) 2.1.3 定数定義 拡張ライブラリが必要な定数はあらかじめ定義しておいた方が良い でしょう．定数を定義する関数は二つあります． void rb_define_const(VALUE class, char *name, VALUE val) void rb_define_global_const(char *name, VALUE val) 前者は特定のクラス/モジュールに属する定数を定義するもの，後 者はグローバルな定数を定義するものです． 2.2 Rubyの機能をCから呼び出す 既に『1.5 Rubyのデータを操作する』で一部紹介したような関数を 使えば，Rubyの機能を実現している関数を直接呼び出すことが出来 ます． # このような関数の一覧表はいまのところありません．ソースを見 # るしかないですね． それ以外にもRubyの機能を呼び出す方法はいくつかあります． 2.2.1 Rubyのプログラムをevalする CからRubyの機能を呼び出すもっとも簡単な方法として，文字列で 与えられたRubyのプログラムを評価する関数があります． VALUE rb_eval_string(char *str) この評価は現在の環境で行われます．つまり，現在のローカル変数 などを受け継ぎます． 2.2.2 IDまたはシンボル Cから文字列を経由せずにRubyのメソッドを呼び出すこともできま す．その前に，Rubyインタプリタ内でメソッドや変数名を指定する 時に使われているIDについて説明しておきましょう． IDとは変数名，メソッド名を表す整数です．Rubyの中では :識別子 でアクセスできます．Cからこの整数を得るためには関数 rb_intern(char *name) を使います．また一文字の演算子はその文字コードがそのままシン ボルになっています．Rubyから引数として与えられたシンボル(ま たは文字列)をIDに変換するには以下の関数を使います． rb_to_id(VALUE symbol) 2.2.3 CからRubyのメソッドを呼び出す Cから文字列を経由せずにRubyのメソッドを呼び出すためには以下 の関数を使います． VALUE rb_funcall(VALUE recv, ID mid, int argc, ...) この関数はオブジェクトrecvのmidで指定されるメソッドを呼び出 します．その他に引数の指定の仕方が違う以下の関数もあります． VALUE rb_funcall2(VALUE recv, ID mid, int argc, VALUE *argv) VALUE rb_apply(VALUE recv, ID mid, VALUE args) applyには引数としてRubyの配列を与えます． 2.2.4 変数/定数を参照/更新する Cから関数を使って参照・更新できるのは，定数，インスタンス変 数です．大域変数は一部のものはCの大域変数としてアクセスでき ます．ローカル変数を参照する方法は公開していません． オブジェクトのインスタンス変数を参照・更新する関数は以下の通 りです． VALUE rb_ivar_get(VALUE obj, ID id) VALUE rb_ivar_set(VALUE obj, ID id, VALUE val) idはrb_intern()で得られるものを使ってください． 定数を参照するには以下の関数を使ってください． VALUE rb_const_get(VALUE obj, ID id) 定数を新しく定義するためには『2.1.3 定数定義』で紹介さ れている関数を使ってください． 3．RubyとCとの情報共有 C言語とRubyの間で情報を共有する方法について解説します． 3.1 Cから参照できるRubyの定数 以下のRubyの定数はCのレベルから参照できる． Qtrue Qfalse 真偽値．QfalseはC言語でも偽とみなされる(つまり0)． Qnil C言語から見た「nil」． 3.2 CとRubyで共有される大域変数 CとRubyで大域変数を使って情報を共有できます．共有できる大域 変数にはいくつかの種類があります．そのなかでもっとも良く使わ れると思われるのはrb_define_variable()です． void rb_define_variable(char *name, VALUE *var) この関数はRubyとCとで共有する大域変数を定義します．変数名が `$'で始まらない時には自動的に追加されます．この変数の値を変 更すると自動的にRubyの対応する変数の値も変わります． またRuby側からは更新できない変数もあります．このread onlyの 変数は以下の関数で定義します． void rb_define_readonly_variable(char *name, VALUE *var) これら変数の他にhookをつけた大域変数を定義できます．hook付き の大域変数は以下の関数を用いて定義します．hook付き大域変数の 値の参照や設定はhookで行う必要があります． void rb_define_hooked_variable(char *name, VALUE *var, VALUE (*getter)(), VALUE (*setter)()) この関数はCの関数によってhookのつけられた大域変数を定義しま す．変数が参照された時には関数getterが，変数に値がセットされ た時には関数setterが呼ばれる．hookを指定しない場合はgetterや setterに0を指定します． # getterもsetterも0ならばrb_define_variable()と同じになる． それから，Cの関数によって実現されるRubyの大域変数を定義する 関数があります． void rb_define_virtual_variable(char *name, VALUE (*getter)(), VALUE (*setter)()) この関数によって定義されたRubyの大域変数が参照された時には getterが，変数に値がセットされた時にはsetterが呼ばれます． getterとsetterの仕様は以下の通りです． (*getter)(ID id, void *data, struct global_entry* entry); (*setter)(VALUE val, ID id, void *data, struct global_entry* entry); 3.3 CのデータをRubyオブジェクトにする Cの世界で定義されたデータ(構造体)をRubyのオブジェクトとして 取り扱いたい場合がありえます．このような場合には，Dataという RubyオブジェクトにCの構造体(へのポインタ)をくるむことでRuby オブジェクトとして取り扱えるようになります． Dataオブジェクトを生成して構造体をRubyオブジェクトにカプセル 化するためには，以下のマクロを使います． Data_Wrap_Struct(class,mark,free,ptr) このマクロの戻り値は生成されたDataオブジェクトです． classはこのDataオブジェクトのクラスです．ptrはカプセル化する Cの構造体へのポインタです．markはこの構造体がRubyのオブジェ クトへの参照がある時に使う関数です．そのような参照を含まない 時には0を指定します． # そのような参照は勧められません． freeはこの構造体がもう不要になった時に呼ばれる関数です．この 関数がガーベージコレクタから呼ばれます． Cの構造体の割当とDataオブジェクトの生成を同時に行うマクロと して以下のものが提供されています． Data_Make_Struct(class, type, mark, free, sval) このマクロの戻り値は生成されたDataオブジェクトです． class, mark, freeはData_Wrap_Structと同じ働きをします．type は割り当てるC構造体の型です．割り当てられた構造体は変数sval に代入されます．この変数の型は (type*) である必要があります． Dataオブジェクトからポインタを取り出すのは以下のマクロを用い ます． Data_Get_Struct(obj, type, sval) Cの構造体へのポインタは変数svalに代入されます． これらのDataの使い方はちょっと分かりにくいので，後で説明する 例題を参照してください． 4．例題 - dbmパッケージを作る ここまでの説明でとりあえず拡張ライブラリは作れるはずです． Rubyのextディレクトリにすでに含まれているdbmモジュールを例に して段階的に説明します． (1) ディレクトリを作る % mkdir ext/dbm Ruby 1.1からは任意のディレクトリでダイナミックライブラリを作 ることができるようになりました．Rubyに静的にリンクする場合に はRubyを展開したディレクトリの下，extディレクトリの中に拡張 モジュール用のディレクトリを作る必要があります．名前は適当に 選んで構いません． (2) MANIFESTファイルを作る % cd ext/dbm % touch MANIFEST 拡張ライブラリのディレクトリの下にはMANIFESTというファイルが 必要なので，とりあえず空のファイルを作っておきます．後でこの ファイルには必要なファイル一覧が入ることになります． MANIFESTというファイルは，静的リンクのmakeの時にディレクトリ が拡張ライブラリを含んでいるかどうか判定するために使われれて います．ダイナミックライブラリを作る場合には必ずしも必要では ありません． (3) 設計する まあ，当然なんですけど，どういう機能を実現するかどうかまず設 計する必要があります．どんなクラスをつくるか，そのクラスには どんなメソッドがあるか，クラスが提供する定数などについて設計 します．dbmクラスについてはext/dbm.docを参照してください． (4) Cコードを書く 拡張ライブラリ本体となるC言語のソースを書きます．C言語のソー スがひとつの時には「モジュール名.c」を選ぶと良いでしょう．C 言語のソースが複数の場合には逆に「モジュール名.c」というファ イル名は避ける必要があります．オブジェクトファイルとモジュー ル生成時に中間的に生成される「モジュール名.o」というファイル とが衝突するからです． Rubyは拡張ライブラリをロードする時に「Init_モジュール名」と いう関数を自動的に実行します．dbmモジュールの場合「Init_dbm」 です．この関数の中でクラス，モジュール，メソッド，定数などの 定義を行います．dbm.cから一部引用します． -- Init_dbm() { /* DBMクラスを定義する */ cDBM = rb_define_class("DBM", rb_cObject); /* DBMはEnumerateモジュールをインクルードする */ rb_include_module(cDBM, rb_mEnumerable); /* DBMクラスのクラスメソッドopen(): 引数はCの配列で受ける */ rb_define_singleton_method(cDBM, "open", fdbm_s_open, -1); /* DBMクラスのメソッドclose(): 引数はなし */ rb_define_method(cDBM, "close", fdbm_close, 0); /* DBMクラスのメソッド[]: 引数は1個 */ rb_define_method(cDBM, "[]", fdbm_fetch, 1); : /* DBMデータを格納するインスタンス変数名のためのID */ id_dbm = rb_intern("dbm"); } -- DBMモジュールはdbmのデータと対応するオブジェクトになるはずで すから，Cの世界のdbmをRubyの世界に取り込む必要があります． dbm.cではData_Make_Structを以下のように使っています． -- struct dbmdata { int di_size; DBM *di_dbm; }; obj = Data_Make_Struct(class,struct dbmdata,0,free_dbm,dbmp); -- ここではdbmstruct構造体へのポインタをDataにカプセル化してい ます．DBM*を直接カプセル化しないのはclose()した時の処理を考 えてのことです． Dataオブジェクトからdbmstruct構造体のポインタを取り出すため に以下のマクロを使っています． -- #define GetDBM(obj, dbmp) {\ Data_Get_Struct(obj, struct dbmdata, dbmp);\ if (dbmp->di_dbm == 0) closed_dbm();\ } -- ちょっと複雑なマクロですが，要するにdbmdata構造体のポインタ の取り出しと，closeされているかどうかのチェックをまとめてい るだけです． DBMクラスにはたくさんメソッドがありますが，分類すると3種類の 引数の受け方があります．ひとつは引数の数が固定のもので，例と してはdeleteメソッドがあります．deleteメソッドを実装している fdbm_delete()はこのようになっています． -- static VALUE fdbm_delete(obj, keystr) VALUE obj, keystr; { : } -- 引数の数が固定のタイプは第1引数がself，第2引数以降がメソッド の引数となります． 引数の数が不定のものはCの配列で受けるものとRubyの配列で受け るものとがあります．dbmモジュールの中で，Cの配列で受けるもの はDBMのクラスメソッドであるopen()です．これを実装している関 数fdbm_s_open()はこうなっています． -- static VALUE fdbm_s_open(argc, argv, class) int argc; VALUE *argv; VALUE class; { : if (rb_scan_args(argc, argv, "11", &file, &vmode) == 1) { mode = 0666; /* default value */ } : } -- このタイプの関数は第1引数が与えられた引数の数，第2引数が与え られた引数の入っている配列になります．selfは第3引数として与 えられます． この配列で与えられた引数を解析するための関数がopen()でも使わ れているrb_scan_args()です．第3引数に指定したフォーマットに 従い，第4変数以降に指定した変数に値を代入してくれます．この フォーマットは，第1文字目が省略できない引数の数，第2文字目が 省略できる引数の数，第3文字目が対応する相手が無いあまりの引 数があるかどうかを示す"*"です．2文字目と3文字目は省略できま す．dbm.cの例では，フォーマットは"11"ですから，引数は最低1つ で，2つまで許されるという意味になります．省略されている時の 変数の値はnil(C言語のレベルではQnil)になります． Rubyの配列で引数を受け取るものはindexesがあります．実装はこ うです． -- static VALUE fdbm_indexes(obj, args) VALUE obj; struct RArray *args; { : } -- 第1引数はself，第2引数はRubyの配列です．ここではキャストを減 らすため struct RArray* で受けていますが，VALUEでも同じこと です． ** 注意事項 Rubyと共有はしないがRubyのオブジェクトを格納する可能性のある Cの大域変数は以下の関数を使ってRubyインタプリタに変数の存在 を教えてあげてください．でないとGCでトラブルを起こします． void rb_global_variable(VALUE *var) (5) extconf.rbを用意する Makefileを作る場合の雛型になるextconf.rbというファイルを作り ます．extconf.rbはモジュールのコンパイルに必要な条件のチェッ クなどを行うことが目的です．extconf.rbの中では以下のRuby関数 を使うことが出来ます． have_library(lib, func): ライブラリの存在チェック have_func(func): 関数の存在チェック have_header(header): ヘッダファイルの存在チェック create_makefile(target): Makefileの生成 以下の変数を使うことができます． $CFLAGS: コンパイル時に追加的に指定するフラグ(-Iなど) $LDFLAGS: リンク時に追加的に指定するフラグ(-Lなど) モジュールをコンパイルする条件が揃わなず，そのモジュールはコ ンパイルしない時にはcreate_makefileを呼ばなければMakefileは 生成されず，コンパイルも行われません． モジュールがRuby 1.1専用である場合には require 'mkmf' をextconf.rbの先頭に置くと便利でしょう． (6) dependを用意する もし，ディレクトリにdependというファイルが存在すれば， Makefileが依存関係をチェックしてくれます． % gcc -MM *.c > depend などで作ることが出来ます．あって損は無いでしょう． (7) MANIFESTファイルにファイル名を入れる % ls > MANIFEST % vi MANIFEST *.o, *~など不必要なファイル以外はMANIFESTに追加しておきます． make時にはMANIFESTの内容は参照しませんので，空のままでも問題 は起きませんが，パッケージングの時に参照することがあるのと， 必要なファイルを区別できるので，用意しておいた方が良いでしょ う． (8) Makefileを生成する Makefileを実際に生成するためには ruby extconf.rb とします．extconf.rbに require 'mkmf' の行がない場合にはエラー になりますので，引数を追加して ruby -r mkmf extconf.rb としてください． ディレクトリをext以下に用意した場合にはRuby全体のmakeの時に 自動的にMakefileが生成されますので，このステップは不要です． (9) makeする 動的リンクライブラリを生成する場合にはその場でmakeしてくださ い．必要であれば make install でインストールされます． ext以下にディレクトリを用意した場合は，Rubyのディレクトリで makeを実行するとMakefileを生成からmake，必要によってはそのモ ジュールのRubyへのリンクまで自動的に実行してくれます． extconf.rbを書き換えるなどしてMakefileの再生成が必要な時はま たRubyディレクトリでmakeしてください． 動的リンクライブラリはmake installでRubyライブラリのディレク トリの下にコピーされます．もしモジュールと協調して使うRubyで 記述されたプログラムがあり，Rubyライブラリに置きたい場合には， 拡張ライブラリ用のディレクトリの下に lib というディレクトリ を作り，そこに 拡張子 .rb のファイルを置いておけば同時にイン ストールされます． (10) デバッグ まあ，デバッグしないと動かないでしょうね．ext/Setupにディレ クトリ名を書くと静的にリンクするのでデバッガが使えるようにな ります．その分コンパイルが遅くなりますけど． (11) できあがり 後はこっそり使うなり，広く公開するなり，売るなり，ご自由にお 使いください．Rubyの作者は拡張ライブラリに関して一切の権利を 主張しません． Appendix A.

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(第3引数はself)．argcが-2の時, 第1引 数がself,

This is used to emulate \fB#!\fR on machines that don't support it, in the following manner: .nf .ne 2 \& #! /usr/local/bin/ruby \& # This line makes the next one a comment in ruby \\ \& exec /usr/local/bin/ruby -S $0 $* .fi On some systems $0 does not always contain the full pathname, so you need \fB-S\fR switch to tell ruby to search for the script if necessary. To handle embedded spaces or such, A better construct than \fB$*\fR would be \fB${1+"$@"}\fR, but it does not work if the script is being interpreted by csh. .TP .B -v --verbose enables verbose mode. Ruby will prints its version at the beginning, and set the variable \fB$VERBOSE\fR to TRUE. Some methods prints extra messages if this variable is TRUE. If this switch is given, and no other arguments present, ruby quits after printing its version. .TP .B --version prints the version of ruby executable. .TP .B -w enables verbose mode without printing version message at the beginning. It set the variable \fB$VERBOSE\fR to TRUE. .TP .B -x\fR[\fIdirectory\fR] tells ruby that the script is embedded in a message. Leading garbage will be discarded until the first that starts with "\fB#!\fR" and contains string "ruby". Any meaningful switches on that line will applied. The end of script must be specified with either EOF, ^D (control-D), ^Z (control-Z), or reserved word __END__.If the directory name is specified, ruby will switch to that directory before executing script. .TP .B -X \fIdirectory causes ruby to switch to the directory. .TP .B -y --yydebug turns on compiler debug mode. ruby will print bunch of internal state messages during compiling scripts. You don't have to specify this switch, unless you are going to debug the ruby interpreter itself. .PP .SH AUTHOR Ruby is designed and implemented by Yukihiro Matsumoto . ruby-1.3/ruby.c100644 1750 1750 36530 6640353076 11754 0ustar matzmatz/************************************************ ruby.c - $Author: matz $ $Date: 1998/12/22 09:01:53 $ created at: Tue Aug 10 12:47:31 JST 1993 Copyright (C) 1993-1998 Yukihiro Matsumoto ************************************************/ #ifdef _WIN32 #include #endif #include "ruby.h" #include "dln.h" #include #include #include #include #ifdef __hpux #include #endif #ifdef HAVE_UNISTD_H #include #endif #ifdef __MWERKS__ #include "node.h" #endif #ifdef USE_CWGUSI #include "macruby_missing.h" #endif #ifndef HAVE_STRING_H char *strchr _((char*,char));

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. [ファイルについて] README.euc : このファイル(注意, 特徴, インストールの方法). MANUAL.euc : マニュアル. lib/, ext/ : ライブラリの実体. sample/ : マニュアル代わりのサンプルプログラム. sample/sample0.rb : tcltklib ライブラリのテスト. sample/sample1.rb : tcltk ライブラリのテスト. tcl/tk (wish) でできそうなことを一通り書いてみました. sample/sample2.rb : tcltk ライブラリのサンプル. maeda shugo (shugo@po.aianet.ne.jp) 氏による (`rb.tk' で書かれていた) ruby のサンプルプログラム http://www.aianet.or.jp/~shugo/ruby/othello.rb.gz を tcltk ライブラリを使うように, 機械的に変更してみました. demo/ : 100 本の線を 100 回描くデモプログラム. 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/ (eof) ruby-1.3/ext/tcltklib/MANUAL.euc100644 1750 1750 10236 6457650104 14703 0ustar matzmatz(tof) 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.

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.

If that matches the * original name, then change the extension to ".~~~". * * If filename is more than 1000 characters long, we die a horrible * death.

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.
