28 | =head1 DESCRIPTION |
29 | ||
30 | This function will split up your program into files that the AutoLoader | |
21c92a1d | 31 | module can handle. It is used by both the standard perl libraries and by |
32 | the MakeMaker utility, to automatically configure libraries for autoloading. | |
33 | ||
34 | The C<autosplit> interface splits the specified file into a hierarchy | |
35 | rooted at the directory C<$dir>. It creates directories as needed to reflect | |
36 | class hierarchy, and creates the file F<autosplit.ix>. This file acts as | |
37 | both forward declaration of all package routines, and as timestamp for the | |
38 | last update of the hierarchy. | |
39 | ||
4e6ea2c3 GS |
40 | The remaining three arguments to C<autosplit> govern other options to |
41 | the autosplitter. | |
42 | ||
43 | =over 2 | |
44 | ||
45 | =item $keep | |
46 | ||
47 | If the third argument, I<$keep>, is false, then any | |
48 | pre-existing C<*.al> files in the autoload directory are removed if | |
49 | they are no longer part of the module (obsoleted functions). | |
50 | $keep defaults to 0. | |
51 | ||
52 | =item $check | |
53 | ||
54 | The | |
55 | fourth argument, I<$check>, instructs C<autosplit> to check the module | |
e8fac187 | 56 | currently being split to ensure that it includes a C<use> |
4e6ea2c3 GS |
57 | specification for the AutoLoader module, and skips the module if |
58 | AutoLoader is not detected. | |
59 | $check defaults to 1. | |
60 | ||
61 | =item $modtime | |
62 | ||
63 | Lastly, the I<$modtime> argument specifies | |
64 | that C<autosplit> is to check the modification time of the module | |
65 | against that of the C<autosplit.ix> file, and only split the module if | |
66 | it is newer. | |
67 | $modtime defaults to 1. | |
68 | ||
69 | =back | |
21c92a1d | 70 | |
71 | Typical use of AutoSplit in the perl MakeMaker utility is via the command-line | |
72 | with: | |
73 | ||
74 | perl -e 'use AutoSplit; autosplit($ARGV[0], $ARGV[1], 0, 1, 1)' | |
75 | ||
76 | Defined as a Make macro, it is invoked with file and directory arguments; | |
77 | C<autosplit> will split the specified file into the specified directory and | |
78 | delete obsolete C<.al> files, after checking first that the module does use | |
79 | the AutoLoader, and ensuring that the module is not already currently split | |
80 | in its current form (the modtime test). | |
81 | ||
82 | The C<autosplit_lib_modules> form is used in the building of perl. It takes | |
83 | as input a list of files (modules) that are assumed to reside in a directory | |
84 | B<lib> relative to the current directory. Each file is sent to the | |
85 | autosplitter one at a time, to be split into the directory B<lib/auto>. | |
86 | ||
87 | In both usages of the autosplitter, only subroutines defined following the | |
4e6ea2c3 | 88 | perl I<__END__> token are split out into separate files. Some |
21c92a1d | 89 | routines may be placed prior to this marker to force their immediate loading |
90 | and parsing. | |
91 | ||
4e6ea2c3 GS |
92 | =head2 Multiple packages |
93 | ||
94 | As of version 1.01 of the AutoSplit module it is possible to have | |
95 | multiple packages within a single file. Both of the following cases | |
96 | are supported: | |
97 | ||
98 | package NAME; | |
99 | __END__ | |
100 | sub AAA { ... } | |
101 | package NAME::option1; | |
102 | sub BBB { ... } | |
103 | package NAME::option2; | |
104 | sub BBB { ... } | |
21c92a1d | 105 | |
4e6ea2c3 GS |
106 | package NAME; |
107 | __END__ | |
108 | sub AAA { ... } | |
109 | sub NAME::option1::BBB { ... } | |
110 | sub NAME::option2::BBB { ... } | |
21c92a1d | 111 | |
112 | =head1 DIAGNOSTICS | |
113 | ||
4e6ea2c3 GS |
114 | C<AutoSplit> will inform the user if it is necessary to create the |
115 | top-level directory specified in the invocation. It is preferred that | |
116 | the script or installation process that invokes C<AutoSplit> have | |
117 | created the full directory path ahead of time. This warning may | |
118 | indicate that the module is being split into an incorrect path. | |
21c92a1d | 119 | |
4e6ea2c3 GS |
120 | C<AutoSplit> will warn the user of all subroutines whose name causes |
121 | potential file naming conflicts on machines with drastically limited | |
122 | (8 characters or less) file name length. Since the subroutine name is | |
123 | used as the file name, these warnings can aid in portability to such | |
124 | systems. | |
21c92a1d | 125 | |
4e6ea2c3 GS |
126 | Warnings are issued and the file skipped if C<AutoSplit> cannot locate |
127 | either the I<__END__> marker or a "package Name;"-style specification. | |
21c92a1d | 128 | |
4e6ea2c3 GS |
129 | C<AutoSplit> will also emit general diagnostics for inability to |
130 | create directories or files. | |
