=head1 NAME |

|
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). |
