120
121lib - manipulate @INC at compile time
122
123=head1 SYNOPSIS
124
125 use lib LIST;
126
127 no lib LIST;
128
129=head1 DESCRIPTION
130
131This is a small simple module which simplifies the manipulation of @INC
132at compile time.
133
134It is typically used to add extra directories to perl's search path so
135that later C<use> or C<require> statements will find modules which are
136not located on perl's default search path.
137
138=head2 Adding directories to @INC
139
140The parameters to C<use lib> are added to the start of the perl search
141path. Saying
142
143 use lib LIST;
144
145is I<almost> the same as saying
146
147 BEGIN { unshift(@INC, LIST) }
148
149For each directory in LIST (called $dir here) the lib module also
150checks to see if a directory called $dir/$archname/auto exists.
151If so the $dir/$archname directory is assumed to be a corresponding
152architecture specific directory and is added to @INC in front of $dir.
153
154The current value of C<$archname> can be found with this command:
155
156 perl -V:archname
157
158To avoid memory leaks, all trailing duplicate entries in @INC are
159removed.
160
161=head2 Deleting directories from @INC
162
163You should normally only add directories to @INC. If you need to
164delete directories from @INC take care to only delete those which you
165added yourself or which you are certain are not needed by other modules
166in your script. Other modules may have added directories which they
167need for correct operation.
168
169The C<no lib> statement deletes all instances of each named directory
170from @INC.
171
172For each directory in LIST (called $dir here) the lib module also
173checks to see if a directory called $dir/$archname/auto exists.
174If so the $dir/$archname directory is assumed to be a corresponding
175architecture specific directory and is also deleted from @INC.
176
177=head2 Restoring original @INC
178
179When the lib module is first loaded it records the current value of @INC
180in an array C<@lib::ORIG_INC>. To restore @INC to that value you
181can say
182
183 @INC = @lib::ORIG_INC;
184
185=head1 CAVEATS
186
187In order to keep lib.pm small and simple, it only works with Unix
188filepaths. This doesn't mean it only works on Unix, but non-Unix
189users must first translate their file paths to Unix conventions.
190
191 # VMS users wanting to put [.stuff.moo] into
192 # their @INC would write
193 use lib 'stuff/moo';
194
195=head1 NOTES
196
197In the future, this module will likely use File::Spec for determining
198paths, as it does now for Mac OS (where Unix-style or Mac-style paths
199work, and Unix-style paths are converted properly to Mac-style paths
200before being added to @INC).
