Hi there,
this might be obvious but how can I find a list of all the perldoc modules?
Perldoc will only work for modules that are installed on your system.
The directories in which Perl will search for modules is given by the
array @INC. You can get a list of directories in @INC with 'perl -V'
(capital V). Perl modules will have a '.pm' file extension.
From 'perldoc -q modules' "How do I find which modules are installed
on my system?"
Since your perldoc isn't working, here it is:
How do I find which modules are installed on my system?
You can use the ExtUtils::Installed module to show all installed dis-
tributions, although it can take awhile to do its magic. The standard
library which comes with Perl just shows up as "Perl" (although you can
get those with Module::CoreList).
use ExtUtils::Installed;
my $inst = ExtUtils::Installed->new();
my @modules = $inst->modules();
If you want a list of all of the Perl module filenames, you can use
File::Find::Rule.
use File::Find::Rule;
my @files = File::Find::Rule->file()->name( '*.pm'
)->in( @INC );
If you do not have that module, you can do the same thing with
File::Find which is part of the standard library.
use File::Find;
: my @files;
find sub { push @files, $File::Find::name if -f _ && /\.pm$/ },
@INC;
print join "\n", @files;
