339 341
340F<staticperl mkbundle> has a number of options to control package 342F<staticperl mkbundle> works by first assembling a list of candidate
341selection. This section describes how they interact with each other. Also, 343files and modules to include, then filtering them by include/exclude
342since I am still a newbie w.r.t. these issues, maybe future versions of 344patterns. The remaining modules (together with their direct dependencies,
343F<staticperl> will change this, so watch out :) 345such as link libraries and L<AutoLoader> files) are then converted into
346bundle files suitable for embedding. F<staticperl mkbundle> can then
347optionally build a new perl interpreter or a standalone application.
344 348
345The idiom "in order" means "in order that they are specified on the
346commandline". If you use a bundle specification file, then the options
347will be processed as if they were given in place of the bundle file name.

355options are processed.
356 354
357=item 2. apply all C<--include> and C<--exclude> options, in order.
358
359All this step does is potentially reduce the number of files already
360selected or found in phase 1.
361
362=item 3. find all modules (== F<.pm> files), gather their static archives
363(F<.a>) and AutoLoader splitfiles (F<.ix> and F<.al> files), find any
364extra libraries they need for linking (F<extralibs.ld>) and optionally
365evaluate any F<.packlist> files.
366
367This step is required to link against XS extensions and also adds files
368required for L<AutoLoader> to do it's job.
369
370=back
371
372After this, all the files selected for bundling will be read and processed
373(stripped), the bundle files will be written, and optionally a new F<perl>
374or application binary will be linked.

387 364
365=item any other argument
366
367Any other argument is interpreted as a bundle specification file, which
368supports all options (without extra quoting), one option per line, in the
369format C<option> or C<option argument>. They will effectively be expanded
370and processed as if they were directly written on the command line, in
371place of the file name.
372
373=back
374
375=item Step 1: gather candidate files and modules
376
377In this step, modules, perl libraries (F<.pl> files) and other files are
378selected for inclusion in the bundle. The relevant options are executed
379in order (this makes a difference mostly for C<--eval>, which can rely on
380earlier C<--use> options to have been executed).
381
382=over 4
383
384=item C<--use> F<module> | C<-M>F<module>
385
386Include the named module and trace direct dependencies. This is done by
387C<use>'ing the module from a fresh package in a subprocess and tracing
388which other modules and files it actually loads.
389
390Example: include AnyEvent and AnyEvent::Impl::Perl.
391
392 staticperl mkbundle --use AnyEvent --use AnyEvent::Impl::Perl
393
394Sometimes you want to load old-style "perl libraries" (F<.pl> files),
395or maybe other weirdly named files. To do that, you need to quote
396the name in single or double quotes (this is because F<staticperl>
397I<literally> just adds the string after the C<require> - which acts
398different when confronted with quoted vs. unquoted strings). When given on
399the command line, you probably need to quote once more to avoid your shell
400interpreting it. Common cases that need this are F<Config_heavy.pl> and
401F<utf8_heavy.pl>.
402
403Example: include the required files for F<perl -V> to work in all its
404glory (F<Config.pm> is included automatically by this).
405
406 # bourne shell
407 staticperl mkbundle --use '"Config_heavy.pl"'
408
409 # bundle specification file
410 use "Config_heavy.pl"
411
412The C<-M>module syntax is included as a convenience that might be easier
413to remember than C<--use> - it's the same switch as perl itself uses
414to load modules. Or maybe it confuses people. Time will tell. Or maybe
415not. Sigh.
416
417=item C<--eval> "perl code" | C<-e> "perl code"
418
419Sometimes it is easier (or necessary) to specify dependencies using perl
420code, or maybe one of the modules you use need a special use statement. In
421that case, you can use C<--eval> to execute some perl snippet or set some
422variables or whatever you need. All files C<require>'d or C<use>'d while
423executing the snippet are included in the final bundle.
424
425Keep in mind that F<mkbundle> will not import any symbols from the modules
426named by the C<--use> option, so do not expect the symbols from modules
427you C<--use>'d earlier on the command line to be available.
428
429Example: force L<AnyEvent> to detect a backend and therefore include it
430in the final bundle.
431
432 staticperl mkbundle --eval 'use AnyEvent; AnyEvent::detect'
433
434 # or like this
435 staticperl mkbundle -MAnyEvent --eval 'AnyEvent::detect'
436
437Example: use a separate "bootstrap" script that C<use>'s lots of modules
438and also include this in the final bundle, to be executed automatically
439when the interpreter is initialised.
440
441 staticperl mkbundle --eval 'do "bootstrap"' --boot bootstrap
442
443=item C<--boot> F<filename>
444
445Include the given file in the bundle and arrange for it to be
446executed (using C<require>) before the main program when the new perl
447is initialised. This can be used to modify C<@INC> or do similar
448modifications before the perl interpreter executes scripts given on the
449command line (or via C<-e>). This works even in an embedded interpreter -
450the file will be executed during interpreter initialisation in that case.
451
452=item C<--incglob> pattern
453
454This goes through all standard library directories and tries to match any
455F<.pm> and F<.pl> files against the extended glob pattern (see below). If
456a file matches, it is added. The pattern is matched against the full path
457of the file (sans the library directory prefix), e.g. F<Sys/Syslog.pm>.
458
459This is very useful to include "everything":
460
461 --incglob '*'
462
463It is also useful for including perl libraries, or trees of those, such as
464the unicode database files needed by some perl built-ins, the regex engine
465and other modules.
466
467 --incglob '/unicore/**.pl'
468
469=item C<--add> F<file> | C<--add> "F<file> alias"
470
471Adds the given (perl) file into the bundle (and optionally call it
472"alias"). The F<file> is either an absolute path or a path relative to
473the current directory. If an alias is specified, then this is the name it
474will use for C<@INC> searches, otherwise the F<file> will be used as the
475internal name.
476
477This switch is used to include extra files into the bundle.
478
479Example: embed the file F<httpd> in the current directory as F<httpd.pm>
480when creating the bundle.
481
482 staticperl mkperl --add "httpd httpd.pm"
483
484Example: add local files as extra modules in the bundle.
485
486 # specification file
487 add file1 myfiles/file1.pm
488 add file2 myfiles/file2.pm
489 add file3 myfiles/file3.pl
490
491 # then later, in perl, use
492 use myfiles::file1;
493 require myfiles::file2;
494 my $res = do "myfiles/file3.pl";
495
496=item C<--binadd> F<file> | C<--add> "F<file> alias"
497
498Just like C<--add>, except that it treats the file as binary and adds it
499without any postprocessing (perl files might get stripped to reduce their
500size).
501
502You should probably add a C</> prefix to avoid clashing with embedded perl
503files (whose paths do not start with C</>), and/or use a special directory
504prefix, such as C</res/name>.
505
506You can later get a copy of these files by calling C<staticperl::find
507"alias">.
508
509An alternative way to embed binary files is to convert them to perl and
510use C<do> to get the contents - this method is a bit cumbersome, but works
511both inside and outside of a staticperl bundle:
512
513 # a "binary" file, call it "bindata.pl"
514 <<'SOME_MARKER'
515 binary data NOT containing SOME_MARKER
516 SOME_MARKER
517
518 # load the binary
519 chomp (my $data = do "bindata.pl");
520
521=back
522
523=item Step 2: filter all files using C<--include> and C<--exclude> options.
524
525After all candidate files and modules are added, they are I<filtered>
526by a combination of C<--include> and C<--exclude> patterns (there is an
527implicit C<--include *> at the end, so if no filters are specified, all
528files are included).
529
530All that this step does is potentially reduce the number of files that are
531to be included - no new files are added during this step.
532
533=over 4
534
535=item C<--include> pattern | C<-i> pattern | C<--exclude> pattern | C<-x> pattern
536
537These specify an include or exclude pattern to be applied to the candidate
538file list. An include makes sure that the given files will be part of the
539resulting file set, an exclude will exclude remaining files. The patterns
540are "extended glob patterns" (see below).
541
542The patterns are applied "in order" - files included via earlier
543C<--include> specifications cannot be removed by any following
544C<--exclude>, and likewise, and file excluded by an earlier C<--exclude>
545cannot be added by any following C<--include>.
546
547For example, to include everything except C<Devel> modules, but still
548include F<Devel::PPPort>, you could use this:
549
550 --incglob '*' -i '/Devel/PPPort.pm' -x '/Devel/**'
551
552=back
553
554=item Step 3: add any extra or "hidden" dependencies.
555
556F<staticperl> currently knows about three extra types of depdendencies
557that are added automatically. Only one (F<.packlist> files) is currently
558optional and can be influenced, the others are always included:
559
560=over 4
561
562=item C<--usepacklists>
563
564Read F<.packlist> files for each distribution that happens to match a
565module name you specified. Sounds weird, and it is, so expect semantics to
566change somehow in the future.
567
568The idea is that most CPAN distributions have a F<.pm> file that matches
569the name of the distribution (which is rather reasonable after all).
570
571If this switch is enabled, then if any of the F<.pm> files that have been
572selected match an install distribution, then all F<.pm>, F<.pl>, F<.al>
573and F<.ix> files installed by this distribution are also included.
574
575For example, using this switch, when the L<URI> module is specified, then
576all L<URI> submodules that have been installed via the CPAN distribution
577are included as well, so you don't have to manually specify them.
578
579=item L<AutoLoader> splitfiles
580
581Some modules use L<AutoLoader> - less commonly (hopefully) used functions
582are split into separate F<.al> files, and an index (F<.ix>) file contains
583the prototypes.
584
585Both F<.ix> and F<.al> files will be detected automatically and added to
586the bundle.
587
588=item link libraries (F<.a> files)
589
590Modules using XS (or any other non-perl language extension compiled at
591installation time) will have a static archive (typically F<.a>). These
592will automatically be added to the linker options in F<bundle.ldopts>.
593
594Should F<staticperl> find a dynamic link library (typically F<.so>) it
595will warn about it - obviously this shouldn't happen unless you use
596F<staticperl> on the wrong perl, or one (probably wrongly) configured to
597use dynamic loading.
598
599=item extra libraries (F<extralibs.ld>)
600
601Some modules need linking against external libraries - these are found in
602F<extralibs.ld> and added to F<bundle.ldopts>.
603
604=back
605
606=item Step 4: write bundle files and optionally link a program
607
608At this point, the select files will be read, processed (stripped) and
609finally the bundle files get written to disk, and F<staticperl mkbundle>
610is normally finished. Optionally, it can go a step further and either link
611a new F<perl> binary with all selected modules and files inside, or build
612a standalone application.
613
614Both the contents of the bundle files and any extra linking is controlled
615by these options:
616
617=over 4

388=item --strip none|pod|ppi 619=item C<--strip> C<none>|C<pod>|C<ppi>

443=item --use module | -Mmodule
444
445Include the named module and all direct dependencies. This is done by
446C<require>'ing the module in a subprocess and tracing which other modules
447and files it actually loads. If the module uses L<AutoLoader>, then all
448splitfiles will be included as well.
449
450Example: include AnyEvent and AnyEvent::Impl::Perl.
451
452 staticperl mkbundle --use AnyEvent --use AnyEvent::Impl::Perl
453
454Sometimes you want to load old-style "perl libraries" (F<.pl> files), or
455maybe other weirdly named files. To do that, you need to quote the name in
456single or double quotes. When given on the command line, you probably need
457to quote once more to avoid your shell interpreting it. Common cases that
458need this are F<Config_heavy.pl> and F<utf8_heavy.pl>.
459
460Example: include the required files for F<perl -V> to work in all its
461glory (F<Config.pm> is included automatically by this).
462
463 # bourne shell
464 staticperl mkbundle --use '"Config_heavy.pl"'
465
466 # bundle specification file
467 use "Config_heavy.pl"
468
469The C<-Mmodule> syntax is included as an alias that might be easier to
470remember than C<use>. Or maybe it confuses people. Time will tell. Or
471maybe not. Argh.
472
473=item --eval "perl code" | -e "perl code"
474
475Sometimes it is easier (or necessary) to specify dependencies using perl
476code, or maybe one of the modules you use need a special use statement. In
477that case, you can use C<eval> to execute some perl snippet or set some
478variables or whatever you need. All files C<require>'d or C<use>'d in the
479script are included in the final bundle.
480
481Keep in mind that F<mkbundle> will only C<require> the modules named
482by the C<--use> option, so do not expect the symbols from modules you
483C<--use>'d earlier on the command line to be available.
484
485Example: force L<AnyEvent> to detect a backend and therefore include it
486in the final bundle.

498=item --boot filename
499
500Include the given file in the bundle and arrange for it to be executed
501(using a C<require>) before anything else when the new perl is
502initialised. This can be used to modify C<@INC> or anything else before
503the perl interpreter executes scripts given on the command line (or via
504C<-e>). This works even in an embedded interpreter.
505
506=item --usepacklist
507
508Read F<.packlist> files for each distribution that happens to match a
509module name you specified. Sounds weird, and it is, so expect semantics to
510change somehow in the future.

512The idea is that most CPAN distributions have a F<.pm> file that matches

526and F<.pl> files against the extended glob pattern (see below). If a file
527matches, it is added. This switch will automatically detect L<AutoLoader>
528files and the required link libraries for XS modules, but it will I<not>
529scan the file for dependencies (at the moment).
530
531This is mainly useful to include "everything":
532
533 --incglob '*'
534
535Or to include perl libraries, or trees of those, such as the unicode
536database files needed by many other modules:
537
538 --incglob '/unicore/**.pl'
539
540=item --add file | --add "file alias"
541
542Adds the given (perl) file into the bundle (and optionally call it
543"alias"). This is useful to include any custom files into the bundle.
544
545Example: embed the file F<httpd> as F<httpd.pm> when creating the bundle.
546
547 staticperl mkperl --add "httpd httpd.pm"
548
549It is also a great way to add any custom modules:
550
551 # specification file
552 add file1 myfiles/file1
553 add file2 myfiles/file2
554 add file3 myfiles/file3
555
556=item --binadd file | --add "file alias"
557
558Just like C<--add>, except that it treats the file as binary and adds it
559without any processing.
560
561You should probably add a C</> prefix to avoid clashing with embedded
562perl files (whose paths do not start with C</>), and/or use a special
563directory, such as C</res/name>.
564
565You can later get a copy of these files by calling C<staticperl::find
566"alias">.
567
568=item --include pattern | -i pattern | --exclude pattern | -x pattern
569
570These two options define an include/exclude filter that is used after all
571files selected by the other options have been found. Each include/exclude
572is applied to all files found so far - an include makes sure that the
573given files will be part of the resulting file set, an exclude will
574exclude files. The patterns are "extended glob patterns" (see below).
575
576For example, to include everything, except C<Devel> modules, but still
577include F<Devel::PPPort>, you could use this:
578
579 --incglob '*' -i '/Devel/PPPort.pm' -x '/Devel/**'
580
581=item --static 678=item C<--static>
582 679
583When C<--perl> is also given, link statically instead of dynamically. The 680Add C<-static> to F<bundle.ldopts>, which means a fully static (if
681supported by the OS) executable will be created. This is not immensely
682useful when just creating the bundle files, but is most useful when
683linking a binary with the C<--perl> or C<--app> options.
684
