=head1 NAME |
| 4 |
|
| 5 |
perlstrip - make perl sources smaller by removing comments, pod, whitespace... |
| 6 |
|
| 7 |
=head1 SYNOPSIS |
| 8 |
|
| 9 |
perlstrip file... |
| 10 |
perlstrip --size --cache file... |
| 11 |
|
| 12 |
-v verbose |
| 13 |
--size optimise for size (also: -s) |
| 14 |
--cache use a cache (also: -c) |
| 15 |
--cache-dir path cache directory to use |
| 16 |
--output path output file for next input file (also: -o) |
| 17 |
|
| 18 |
WARNING: like its counterpart strip, by default files are overwritten! |
| 19 |
|
| 20 |
=head1 DESCRIPTION |
| 21 |
|
| 22 |
This program can be used to reduce the filesize of perl sources, for |
| 23 |
example, before bundling them using L<PAR>, L<App::Staticperl>, or when |
| 24 |
using them in a situation where disk space is premium (such as within |
| 25 |
firmwares, boot floppies etc.). |
| 26 |
|
| 27 |
It does this by removing unnecessary whitespace, commands, POD and a few |
| 28 |
other things. |
| 29 |
|
| 30 |
By default, it works through the list of files given on the commandline, |
| 31 |
strips them and writes them again. This can be influenced via switches. |
| 32 |
|
| 33 |
=head2 OPTIONS |
| 34 |
|
| 35 |
=over 4 |
| 36 |
|
| 37 |
=item C<--verbose> |
| 38 |
|
| 39 |
=item C<-v> |
| 40 |
|
| 41 |
Increases verbosity - highly recommended for interactive use. |
| 42 |
|
| 43 |
=item C<--output> path |
| 44 |
|
| 45 |
=item C<-o> path |
| 46 |
|
| 47 |
Write the stripped contents of the I<following> files on the commandline |
| 48 |
to this path, instead of overwriting the original file. This can be used |
| 49 |
to copy files instead of (destructively) overwriting them, by specifying |
| 50 |
C<-o> before each file, e.g.: |
| 51 |
|
| 52 |
perlstrip -o strippedfile origsource |
| 53 |
|
| 54 |
=item C<--size> |
| 55 |
|
| 56 |
=item C<-s> |
| 57 |
|
| 58 |
Optimise for size instead of for compressibility - the default is to |
| 59 |
optimise the file for later compression. Optimising for size makes the raw |
| 60 |
file size smaller, but might compress a bit worse. |
| 61 |
|
| 62 |
=item C<--cache> |
| 63 |
|
| 64 |
=item C<-c> |
| 65 |
|
| 66 |
Stripping files can take a very long time. When this option is enabled, |
| 67 |
then C<perlstrip> will cache larger files in a special directory |
| 68 |
(default: F<~/.cache/perlstrip>), to improve repeated calls to strip |
| 69 |
sources. |
| 70 |
|
| 71 |
This is mainly useful when you strip a whole perl installation repeatedly. |
| 72 |
|
| 73 |
=item C<--cache-dir> path |
| 74 |
|
| 75 |
Enables caching, but uses an alternative cache directory (which will be |
| 76 |
created if it doesn't exist yet). |
