33 | WHOA THERE! It looks like you've got some fancy dashes in your commandline! |
34 | These are *not* the traditional -- dashes that software recognizes. You |
35 | probably got these by copy-pasting from the perldoc for this module as |
36 | rendered by a UTF8-capable formatter. This most typically happens on an OS X |
37 | terminal, but can happen elsewhere too. Please try again after replacing the |
38 | dashes with normal minus signs. |

325 | =head1 NAME |
326 | |
327 | local::lib - create and use a local lib/ for perl modules with PERL5LIB |
328 | |
329 | =head1 SYNOPSIS |
330 | |
331 | In code - |
332 | |
333 | use local::lib; # sets up a local lib at ~/perl5 |
334 | |
335 | use local::lib '~/foo'; # same, but ~/foo |
336 | |
1bc71e56 |
337 | # Or... |
338 | use FindBin; |
339 | use local::lib "$FindBin::Bin/../support"; # app-local support library |
340 | |
b5cc15f7 |
341 | From the shell - |
342 | |
0fb70b9a |
343 | # Install LWP and it's missing dependencies to the 'my_lwp' directory |
344 | perl -MCPAN -Mlocal::lib=my_lwp -e 'CPAN::install(LWP)' |
345 | |
346 | # Install LWP and *all non-core* dependencies to the 'my_lwp' directory |
347 | perl -MCPAN -Mlocal::lib=--self-contained,my_lwp -e 'CPAN::install(LWP)' |
348 | |
349 | # Just print out useful shell commands |
b5cc15f7 |
350 | $ perl -Mlocal::lib |
351 | export MODULEBUILDRC=/home/username/perl/.modulebuildrc |
352 | export PERL_MM_OPT='INSTALL_BASE=/home/username/perl' |
353 | export PERL5LIB='/home/username/perl/lib/perl5:/home/username/perl/lib/perl5/i386-linux' |
354 | export PATH="/home/username/perl/bin:$PATH" |
355 | |
bc30e1d5 |
356 | To bootstrap if you don't have local::lib itself installed - |
357 | |
e423efce |
358 | <download local::lib tarball from CPAN, unpack and cd into dir> |
715c31a0 |
359 | |
bc30e1d5 |
360 | $ perl Makefile.PL --bootstrap |
361 | $ make test && make install |
715c31a0 |
362 | |
dc8ddd06 |
363 | $ echo 'eval $(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib)' >>~/.bashrc |
715c31a0 |
364 | |
618272fe |
365 | # Or for C shells... |
715c31a0 |
366 | |
618272fe |
367 | $ /bin/csh |
368 | % echo $SHELL |
369 | /bin/csh |
370 | % perl -I$HOME/perl5/lib/perl5 -Mlocal::lib >> ~/.cshrc |
dc8ddd06 |
371 | |
8b1e8e69 |
372 | You can also pass --boostrap=~/foo to get a different location - |
373 | |
374 | $ perl Makefile.PL --bootstrap=~/foo |
375 | $ make test && make install |
376 | |
377 | $ echo 'eval $(perl -I$HOME/foo/lib/perl5 -Mlocal::lib=$HOME/foo)' >>~/.bashrc |
618272fe |
378 | |
977a9ca3 |
379 | If you want to install multiple Perl module environments, say for application evelopment, |
380 | install local::lib globally and then: |
381 | |
382 | $ cd ~/mydir1 |
383 | $ perl -Mlocal::lib=./ |
384 | $ eval $(perl -Mlocal::lib=./) ### To set the environment for this shell alone |
385 | $ printenv ### You will see that ~/mydir1 is in the PERL5LIB |
386 | $ perl -MCPAN -e install ... ### whatever modules you want |
387 | $ cd ../mydir2 |
388 | ... REPEAT ... |
389 | |
390 | For multiple environments for multiple apps you may need to include a modified version of |
391 | the C<< use FindBin >> instructions in the "In code" sample above. If you did something like |
392 | the above, you have a set of Perl modules at C<< ~/mydir1/lib >>. If you have a script at |
393 | C<< ~/mydir1/scripts/myscript.pl >>, you need to tell it where to find the modules you installed |
c4dbb66c |
394 | for it at C<< ~/mydir1/lib >>. |
977a9ca3 |
395 | |
396 | In C<< ~/mydir1/scripts/myscript.pl >>: |
397 | |
398 | use strict; |
399 | use warnings; |
400 | use local::lib "$FindBin::Bin/.."; ### points to ~/mydir1 and local::lib finds lib |
401 | use lib "$FindBin::Bin/../lib"; ### points to ~/mydir1/lib |
402 | |
403 | Put this before any BEGIN { ... } blocks that require the modules you installed. |

405 | =head1 DESCRIPTION |
406 | |
407 | This module provides a quick, convenient way of bootstrapping a user-local Perl |
408 | module library located within the user's home directory. It also constructs and |
409 | prints out for the user the list of environment variables using the syntax |
410 | appropriate for the user's current shell (as specified by the C<SHELL> |
411 | environment variable), suitable for directly adding to one's shell configuration |
412 | file. |
dc8ddd06 |
413 | |
1bc71e56 |
414 | More generally, local::lib allows for the bootstrapping and usage of a directory |
415 | containing Perl modules outside of Perl's C<@INC>. This makes it easier to ship |
416 | an application with an app-specific copy of a Perl module, or collection of |
417 | modules. Useful in cases like when an upstream maintainer hasn't applied a patch |
418 | to a module of theirs that you need for your application. |
419 | |
420 | On import, local::lib sets the following environment variables to appropriate |
421 | values: |
422 | |
423 | =over 4 |
424 | |
425 | =item MODULEBUILDRC |
426 | |
427 | =item PERL_MM_OPT |
428 | |
429 | =item PERL5LIB |
430 | |
431 | =item PATH |
432 | |
433 | PATH is appended to, rather than clobbered. |
434 | |
435 | =back |
436 | |
437 | These values are then available for reference by any code after import. |

562 | Calls the following in a pipeline, passing the result from the previous to the |
563 | next, in an attempt to find where to configure the environment for a local |
564 | library installation: L</resolve_empty_path>, L</resolve_home_path>, |
565 | L</resolve_relative_path>. Passes the given path argument to |
566 | L</resolve_empty_path> which then returns a result that is passed to |
567 | L</resolve_home_path>, which then has its result passed to |
568 | L</resolve_relative_path>. The result of this final call is returned from |
569 | L</resolve_path>. |

571 | =head1 A WARNING ABOUT UNINST=1 |
572 | |
573 | Be careful about using local::lib in combination with "make install UNINST=1". |
574 | The idea of this feature is that will uninstall an old version of a module |
575 | before installing a new one. However it lacks a safety check that the old |
576 | version and the new version will go in the same directory. Used in combination |
577 | with local::lib, you can potentially delete a globally accessible version of a |
381738d7 |
578 | module while installing the new version in a local place. Only combine "make |
0fb70b9a |
579 | install UNINST=1" and local::lib if you understand these possible consequences. |

583 | Rather basic shell detection. Right now anything with csh in its name is |
584 | assumed to be a C shell or something compatible, and everything else is assumed |
1bc71e56 |
585 | to be Bourne. If the C<SHELL> environment variable is not set, a |
586 | Bourne-compatible shell is assumed. |

587 | |
588 | Bootstrap is a hack and will use CPAN.pm for ExtUtils::MakeMaker even if you |
589 | have CPANPLUS installed. |
590 | |
591 | Kills any existing PERL5LIB, PERL_MM_OPT or MODULEBUILDRC. |

593 | Should probably auto-fixup CPAN config if not already done. |

597 | =head1 TROUBLESHOOTING |
598 | |
599 | If you've configured local::lib to install CPAN modules somewhere in to your |
600 | home directory, and at some point later you try to install a module with C<cpan |
601 | -i Foo::Bar>, but it fails with an error like: C<Warning: You do not have |
602 | permissions to install into /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux at |
603 | /usr/lib64/perl5/5.8.8/Foo/Bar.pm> and buried within the install log is an |
604 | error saying C<'INSTALL_BASE' is not a known MakeMaker parameter name>, then |
605 | you've somehow lost your updated ExtUtils::MakeMaker module. |
606 | |
607 | To remedy this situation, rerun the bootstrapping procedure documented above. |
608 | |
609 | Then, run C<rm -r ~/.cpan/build/Foo-Bar*> |
610 | |
611 | Finally, re-run C<cpan -i Foo::Bar> and it should install without problems. |
