76 | =head1 NAME |
77 | ||
78 | perlmodlib - constructing new Perl modules and finding existing ones | |
79 | ||
2e1d04bc JH |
80 | =head1 THE PERL MODULE LIBRARY |
81 | ||
7ef5744c | 82 | Many modules are included in the Perl distribution. These are described |
2e1d04bc | 83 | below, and all end in F<.pm>. You may discover compiled library |
7ef5744c | 84 | files (usually ending in F<.so>) or small pieces of modules to be |
2e1d04bc JH |
85 | autoloaded (ending in F<.al>); these were automatically generated |
86 | by the installation process. You may also discover files in the | |
87 | library directory that end in either F<.pl> or F<.ph>. These are | |
88 | old libraries supplied so that old programs that use them still | |
89 | run. The F<.pl> files will all eventually be converted into standard | |
90 | modules, and the F<.ph> files made by B<h2ph> will probably end up | |
91 | as extension modules made by B<h2xs>. (Some F<.ph> values may | |
92 | already be available through the POSIX, Errno, or Fcntl modules.) | |
93 | The B<pl2pm> file in the distribution may help in your conversion, | |
94 | but it's just a mechanical process and therefore far from bulletproof. | |
95 | ||
96 | =head2 Pragmatic Modules | |
97 | ||
98 | They work somewhat like compiler directives (pragmata) in that they | |
99 | tend to affect the compilation of your program, and thus will usually | |
100 | work well only when used within a C<use>, or C<no>. Most of these | |
101 | are lexically scoped, so an inner BLOCK may countermand them | |
102 | by saying: | |
103 | ||
104 | no integer; | |
105 | no strict 'refs'; | |
106 | no warnings; | |
107 | ||
108 | which lasts until the end of that BLOCK. | |
109 | ||
110 | Some pragmas are lexically scoped--typically those that affect the | |
111 | C<$^H> hints variable. Others affect the current package instead, | |
112 | like C<use vars> and C<use subs>, which allow you to predeclare a | |
113 | variables or subroutines within a particular I<file> rather than | |
114 | just a block. Such declarations are effective for the entire file | |
115 | for which they were declared. You cannot rescind them with C<no | |
116 | vars> or C<no subs>. | |
117 | ||
118 | The following pragmas are defined (and have their own documentation). | |
119 | ||
120 | =over 12 | |
121 | ||
122 | EOF | |
123 | ||
124 | print OUT $_ for (sort @pragma); | |
125 | ||
126 | print OUT <<EOF; | |
127 | =back | |
128 | ||
129 | =head2 Standard Modules | |
130 | ||
131 | Standard, bundled modules are all expected to behave in a well-defined | |
132 | manner with respect to namespace pollution because they use the | |
133 | Exporter module. See their own documentation for details. | |
134 | ||
7ef5744c RGS |
135 | It's possible that not all modules listed below are installed on your |
136 | system. For example, the GDBM_File module will not be installed if you | |
137 | don't have the gdbm library. | |
138 | ||
2e1d04bc JH |
139 | =over 12 |
140 | ||
141 | EOF | |
142 | ||
143 | print OUT $_ for (sort @mod); | |
144 | ||
145 | print OUT <<'EOF'; | |
146 | =back | |
147 | ||
148 | To find out I<all> modules installed on your system, including | |
149 | those without documentation or outside the standard release, | |
a4373870 CW |
150 | just use the following command (under the default win32 shell, |
151 | double quotes should be used instead of single quotes). | |
2e1d04bc | 152 | |
a4373870 CW |
153 | % perl -MFile::Find=find -MFile::Spec::Functions -Tlwe \ |
154 | 'find { wanted => sub { print canonpath $_ if /\.pm\z/ }, | |
155 | no_chdir => 1 }, @INC' | |
2e1d04bc | 156 | |
8518420c | 157 | (The -T is here to prevent '.' from being listed in @INC.) |
2e1d04bc JH |
158 | They should all have their own documentation installed and accessible |
159 | via your system man(1) command. If you do not have a B<find> | |
160 | program, you can use the Perl B<find2perl> program instead, which | |
161 | generates Perl code as output you can run through perl. If you | |
162 | have a B<man> program but it doesn't find your modules, you'll have | |
163 | to fix your manpath. See L<perl> for details. If you have no | |
164 | system B<man> command, you might try the B<perldoc> program. | |
165 | ||
8518420c RGS |
166 | Note also that the command C<perldoc perllocal> gives you a (possibly |
167 | incomplete) list of the modules that have been further installed on | |
168 | your system. (The perllocal.pod file is updated by the standard MakeMaker | |
169 | install process.) | |
170 | ||
2e1d04bc JH |
171 | =head2 Extension Modules |
172 | ||
173 | Extension modules are written in C (or a mix of Perl and C). They | |
174 | are usually dynamically loaded into Perl if and when you need them, | |
da75cd15 | 175 | but may also be linked in statically. Supported extension modules |
2e1d04bc JH |
176 | include Socket, Fcntl, and POSIX. |
177 | ||
178 | Many popular C extension modules do not come bundled (at least, not | |
179 | completely) due to their sizes, volatility, or simply lack of time | |
180 | for adequate testing and configuration across the multitude of | |
181 | platforms on which Perl was beta-tested. You are encouraged to | |
182 | look for them on CPAN (described below), or using web search engines | |
7ef5744c | 183 | like Alta Vista or Google. |
2e1d04bc JH |
184 | |
185 | =head1 CPAN | |
186 | ||
187 | CPAN stands for Comprehensive Perl Archive Network; it's a globally | |
188 | replicated trove of Perl materials, including documentation, style | |
189 | guides, tricks and traps, alternate ports to non-Unix systems and | |
190 | occasional binary distributions for these. Search engines for | |
1577cd80 | 191 | CPAN can be found at http://www.cpan.org/ |
2e1d04bc JH |
192 | |
193 | Most importantly, CPAN includes around a thousand unbundled modules, | |
194 | some of which require a C compiler to build. Major categories of | |
195 | modules are: | |

929 | =head1 Modules: Creation, Use, and Abuse | |
930 | ||
931 | (The following section is borrowed directly from Tim Bunce's modules | |
932 | file, available at your nearest CPAN site.) | |
933 | ||
934 | Perl implements a class using a package, but the presence of a | |
935 | package doesn't imply the presence of a class. A package is just a | |
936 | namespace. A class is a package that provides subroutines that can be | |
937 | used as methods. A method is just a subroutine that expects, as its | |
938 | first argument, either the name of a package (for "static" methods), | |
939 | or a reference to something (for "virtual" methods). | |
940 | ||
941 | A module is a file that (by convention) provides a class of the same | |
942 | name (sans the .pm), plus an import method in that class that can be | |
943 | called to fetch exported symbols. This module may implement some of | |
944 | its methods by loading dynamic C or C++ objects, but that should be | |
945 | totally transparent to the user of the module. Likewise, the module | |
946 | might set up an AUTOLOAD function to slurp in subroutine definitions on | |
947 | demand, but this is also transparent. Only the F<.pm> file is required to | |
948 | exist. See L<perlsub>, L<perltoot>, and L<AutoLoader> for details about | |
949 | the AUTOLOAD mechanism. | |

957 | Do similar modules already exist in some form? | |
2e1d04bc JH |
958 | |
959 | If so, please try to reuse the existing modules either in whole or | |
960 | by inheriting useful features into a new class. If this is not | |
961 | practical try to get together with the module authors to work on | |
962 | extending or enhancing the functionality of the existing modules. | |
963 | A perfect example is the plethora of packages in perl4 for dealing | |
964 | with command line options. | |
965 | ||
966 | If you are writing a module to expand an already existing set of | |
967 | modules, please coordinate with the author of the package. It | |
968 | helps if you follow the same naming scheme and module interaction | |
969 | scheme as the original author. | |
970 | ||
ac634a9a JH |
971 | =item * |
972 | ||
973 | Try to design the new module to be easy to extend and reuse. | |
2e1d04bc JH |
974 | |
975 | Try to C<use warnings;> (or C<use warnings qw(...);>). | |
976 | Remember that you can add C<no warnings qw(...);> to individual blocks | |
977 | of code that need less warnings. | |
978 | ||
979 | Use blessed references. Use the two argument form of bless to bless | |
980 | into the class name given as the first parameter of the constructor, | |
981 | e.g.,: | |
982 | ||
983 | sub new { | |
984 | my $class = shift; | |
985 | return bless {}, $class; | |
986 | } | |
987 | ||
988 | or even this if you'd like it to be used as either a static | |
989 | or a virtual method. | |
990 | ||
991 | sub new { | |
992 | my $self = shift; | |
993 | my $class = ref($self) || $self; | |
994 | return bless {}, $class; | |
995 | } | |
996 | ||
997 | Pass arrays as references so more parameters can be added later | |
998 | (it's also faster). Convert functions into methods where | |
999 | appropriate. Split large methods into smaller more flexible ones. | |
1000 | Inherit methods from other modules if appropriate. | |
1001 | ||
1002 | Avoid class name tests like: C<die "Invalid" unless ref $ref eq 'FOO'>. | |
1003 | Generally you can delete the C<eq 'FOO'> part with no harm at all. | |
1004 | Let the objects look after themselves! Generally, avoid hard-wired | |
1005 | class names as far as possible. | |
1006 | ||
1007 | Avoid C<< $r->Class::func() >> where using C<@ISA=qw(... Class ...)> and | |
1008 | C<< $r->func() >> would work (see L<perlbot> for more details). | |
1009 | ||
1010 | Use autosplit so little used or newly added functions won't be a | |
1011 | burden to programs that don't use them. Add test functions to | |
1012 | the module after __END__ either using AutoSplit or by saying: | |
1013 | ||
1014 | eval join('',<main::DATA>) || die $@ unless caller(); | |
1015 | ||
1016 | Does your module pass the 'empty subclass' test? If you say | |
1017 | C<@SUBCLASS::ISA = qw(YOURCLASS);> your applications should be able | |
1018 | to use SUBCLASS in exactly the same way as YOURCLASS. For example, | |
1019 | does your application still work if you change: C<$obj = new YOURCLASS;> | |
1020 | into: C<$obj = new SUBCLASS;> ? | |
1021 | ||
1022 | Avoid keeping any state information in your packages. It makes it | |
1023 | difficult for multiple other packages to use yours. Keep state | |
1024 | information in objects. | |
1025 | ||
1026 | Always use B<-w>. | |
1027 | ||
1028 | Try to C<use strict;> (or C<use strict qw(...);>). | |
1029 | Remember that you can add C<no strict qw(...);> to individual blocks | |
1030 | of code that need less strictness. | |
1031 | ||
1032 | Always use B<-w>. | |
1033 | ||
1034 | Follow the guidelines in the perlstyle(1) manual. | |
1035 | ||
1036 | Always use B<-w>. | |

1039 | ||
1040 | Some simple style guidelines | |
2e1d04bc JH |
1041 | |
1042 | The perlstyle manual supplied with Perl has many helpful points. | |
1043 | ||
1044 | Coding style is a matter of personal taste. Many people evolve their | |
1045 | style over several years as they learn what helps them write and | |
1046 | maintain good code. Here's one set of assorted suggestions that | |
1047 | seem to be widely used by experienced developers: | |
1048 | ||
1049 | Use underscores to separate words. It is generally easier to read | |
1050 | $var_names_like_this than $VarNamesLikeThis, especially for | |
1051 | non-native speakers of English. It's also a simple rule that works | |
1052 | consistently with VAR_NAMES_LIKE_THIS. | |
1053 | ||
1054 | Package/Module names are an exception to this rule. Perl informally | |
1055 | reserves lowercase module names for 'pragma' modules like integer | |
1056 | and strict. Other modules normally begin with a capital letter and | |
1057 | use mixed case with no underscores (need to be short and portable). | |
1058 | ||
1059 | You may find it helpful to use letter case to indicate the scope | |
1060 | or nature of a variable. For example: | |
1061 | ||
1062 | $ALL_CAPS_HERE constants only (beware clashes with Perl vars) | |
1063 | $Some_Caps_Here package-wide global/static | |
1064 | $no_caps_here function scope my() or local() variables | |
1065 | ||
1066 | Function and method names seem to work best as all lowercase. | |
1067 | e.g., C<< $obj->as_string() >>. | |
1068 | ||
1069 | You can use a leading underscore to indicate that a variable or | |
1070 | function should not be used outside the package that defined it. | |
1071 | ||
ac634a9a JH |
1072 | =item * |
1073 | ||
1074 | Select what to export. | |
2e1d04bc JH |
1075 | |
1076 | Do NOT export method names! | |
1077 | ||
1078 | Do NOT export anything else by default without a good reason! | |
1079 | ||
1080 | Exports pollute the namespace of the module user. If you must | |
1081 | export try to use @EXPORT_OK in preference to @EXPORT and avoid | |
1082 | short or common names to reduce the risk of name clashes. | |
1083 | ||
1084 | Generally anything not exported is still accessible from outside the | |
1085 | module using the ModuleName::item_name (or C<< $blessed_ref->method >>) | |
1086 | syntax. By convention you can use a leading underscore on names to | |
1087 | indicate informally that they are 'internal' and not for public use. | |
1088 | ||
1089 | (It is actually possible to get private functions by saying: | |
1090 | C<my $subref = sub { ... }; &$subref;>. But there's no way to call that | |
1091 | directly as a method, because a method must have a name in the symbol | |
1092 | table.) | |
1093 | ||
1094 | As a general rule, if the module is trying to be object oriented | |
1095 | then export nothing. If it's just a collection of functions then | |
1096 | @EXPORT_OK anything but use @EXPORT with caution. | |
1097 | ||
ac634a9a JH |
1098 | =item * |
1099 | ||
1100 | Select a name for the module. | |
2e1d04bc JH |
1101 | |
1102 | This name should be as descriptive, accurate, and complete as | |
1103 | possible. Avoid any risk of ambiguity. Always try to use two or | |
1104 | more whole words. Generally the name should reflect what is special | |
1105 | about what the module does rather than how it does it. Please use | |
1106 | nested module names to group informally or categorize a module. | |
1107 | There should be a very good reason for a module not to have a nested name. | |
1108 | Module names should begin with a capital letter. | |
1109 | ||
1110 | Having 57 modules all called Sort will not make life easy for anyone | |
1111 | (though having 23 called Sort::Quick is only marginally better :-). | |
1112 | Imagine someone trying to install your module alongside many others. | |
1113 | If in any doubt ask for suggestions in comp.lang.perl.misc. | |
1114 | ||
1115 | If you are developing a suite of related modules/classes it's good | |
1116 | practice to use nested classes with a common prefix as this will | |
1117 | avoid namespace clashes. For example: Xyz::Control, Xyz::View, | |
1118 | Xyz::Model etc. Use the modules in this list as a naming guide. | |
1119 | ||
1120 | If adding a new module to a set, follow the original author's | |
1121 | standards for naming modules and the interface to methods in | |
1122 | those modules. | |
1123 | ||
4844a3be SP |
1124 | If developing modules for private internal or project specific use, |
1125 | that will never be released to the public, then you should ensure | |
1126 | that their names will not clash with any future public module. You | |
1127 | can do this either by using the reserved Local::* category or by | |
1128 | using a category name that includes an underscore like Foo_Corp::*. | |
1129 | ||
2e1d04bc JH |
1130 | To be portable each component of a module name should be limited to |
1131 | 11 characters. If it might be used on MS-DOS then try to ensure each is | |
1132 | unique in the first 8 characters. Nested modules make this easier. | |
1133 | ||

1136 | Have you got it right? | |
2e1d04bc JH |
1137 | |
1138 | How do you know that you've made the right decisions? Have you | |
1139 | picked an interface design that will cause problems later? Have | |
1140 | you picked the most appropriate name? Do you have any questions? | |
1141 | ||
1142 | The best way to know for sure, and pick up many helpful suggestions, | |
1143 | is to ask someone who knows. Comp.lang.perl.misc is read by just about | |
1144 | all the people who develop modules and it's the best place to ask. | |
1145 | ||
1146 | All you need to do is post a short summary of the module, its | |
1147 | purpose and interfaces. A few lines on each of the main methods is | |
1148 | probably enough. (If you post the whole module it might be ignored | |
1149 | by busy people - generally the very people you want to read it!) | |
1150 | ||
1151 | Don't worry about posting if you can't say when the module will be | |
1152 | ready - just say so in the message. It might be worth inviting | |
1153 | others to help you, they may be able to complete it for you! | |

1210 | Perl, for example, is supplied with two types of licence: The GNU GPL |
1211 | and The Artistic Licence (see the files README, Copying, and Artistic, | |
1212 | or L<perlgpl> and L<perlartistic>). Larry has good reasons for NOT | |
1213 | just using the GNU GPL. | |
2e1d04bc JH |
1214 | |
1215 | My personal recommendation, out of respect for Larry, Perl, and the | |
1216 | Perl community at large is to state something simply like: | |
1217 | ||
1218 | Copyright (c) 1995 Your Name. All rights reserved. | |
1219 | This program is free software; you can redistribute it and/or | |
1220 | modify it under the same terms as Perl itself. | |
1221 | ||
1222 | This statement should at least appear in the README file. You may | |
1223 | also wish to include it in a Copying file and your source files. | |
1224 | Remember to include the other words in addition to the Copyright. | |

1228 | Give the module a version/issue/release number. | |
2e1d04bc JH |
1229 | |
1230 | To be fully compatible with the Exporter and MakeMaker modules you | |
1231 | should store your module's version number in a non-my package | |
1232 | variable called $VERSION. This should be a floating point | |
1233 | number with at least two digits after the decimal (i.e., hundredths, | |
1234 | e.g, C<$VERSION = "0.01">). Don't use a "1.3.2" style version. | |
1235 | See L<Exporter> for details. | |
1236 | ||
1237 | It may be handy to add a function or method to retrieve the number. | |
1238 | Use the number in announcements and archive file names when | |
1239 | releasing the module (ModuleName-1.02.tar.Z). | |
1240 | See perldoc ExtUtils::MakeMaker.pm for details. | |

1244 | How to release and distribute a module. | |
2e1d04bc JH |
1245 | |
1246 | It's good idea to post an announcement of the availability of your | |
1247 | module (or the module itself if small) to the comp.lang.perl.announce | |
1248 | Usenet newsgroup. This will at least ensure very wide once-off | |
1249 | distribution. | |
1250 | ||
1251 | If possible, register the module with CPAN. You should | |
1252 | include details of its location in your announcement. | |
1253 | ||
1254 | Some notes about ftp archives: Please use a long descriptive file | |
1255 | name that includes the version number. Most incoming directories | |
1256 | will not be readable/listable, i.e., you won't be able to see your | |
1257 | file after uploading it. Remember to send your email notification | |
1258 | message as soon as possible after uploading else your file may get | |
1259 | deleted automatically. Allow time for the file to be processed | |
1260 | and/or check the file has been processed before announcing its | |
1261 | location. | |
1262 | ||
1263 | FTP Archives for Perl Modules: | |
1264 | ||
1265 | Follow the instructions and links on: | |

1268 | http://www.cpan.org/modules/04pause.html | |

1272 | https://pause.kbx.de/pause/ | |
1273 | http://pause.perl.org/pause/ | |
1274 | ||
1275 | and notify <modules@perl.org>. | |
1276 | ||
1277 | By using the WWW interface you can ask the Upload Server to mirror | |
1278 | your modules from your ftp or WWW site into your own directory on | |
1279 | CPAN! | |
1280 | ||

2e1d04bc JH |
1286 | |
1287 | Always strive to remain compatible with previous released versions. | |
1288 | Otherwise try to add a mechanism to revert to the | |

1301 | There is no requirement to convert anything. | |
2e1d04bc JH |
1302 | |
1303 | If it ain't broke, don't fix it! Perl 4 library scripts should | |
1304 | continue to work with no problems. You may need to make some minor | |
1305 | changes (like escaping non-array @'s in double quoted strings) but | |
1306 | there is no need to convert a .pl file into a Module for just that. | |
1307 | ||
ac634a9a JH |
1308 | =item * |
1309 | ||
1310 | Consider the implications. | |
2e1d04bc JH |
1311 | |
1312 | All Perl applications that make use of the script will need to | |
1313 | be changed (slightly) if the script is converted into a module. Is | |
1314 | it worth it unless you plan to make other changes at the same time? | |
1315 | ||
ac634a9a JH |
1316 | =item * |
1317 | ||
1318 | Make the most of the opportunity. | |
2e1d04bc JH |
1319 | |
1320 | If you are going to convert the script to a module you can use the | |
1321 | opportunity to redesign the interface. The guidelines for module | |
1322 | creation above include many of the issues you should consider. | |

ac634a9a | 1382 | In some cases the 'application' can then be reduced to a small |
2e1d04bc JH |
1383 | |
1384 | fragment of code built on top of the reusable modules. In these cases | |
1385 | the application could invoked as: | |
1386 | ||
1387 | % perl -e 'use Module::Name; method(@ARGV)' ... | |
1388 | or | |

1393 | =head1 NOTE | |
1394 | ||
1395 | Perl does not enforce private and public parts of its modules as you may | |
1396 | have been used to in other languages like C++, Ada, or Modula-17. Perl | |
1397 | doesn't have an infatuation with enforced privacy. It would prefer | |
1398 | that you stayed out of its living room because you weren't invited, not | |
1399 | because it has a shotgun. | |
1400 | ||
1401 | The module and its user have a contract, part of which is common law, | |
1402 | and part of which is "written". Part of the common law contract is | |
1403 | that a module doesn't pollute any namespace it wasn't asked to. The | |
1404 | written contract for the module (A.K.A. documentation) may make other | |
1405 | provisions. But then you know when you C<use RedefineTheWorld> that | |
1406 | you're redefining the world and willing to take the consequences. | |
