An addition for UNIX books to read
I wanted to add this to the FAQ section on which UNIX books should be read, but the thread is closed. One of my all time favorites is now available for free download, "UNIX Text Processing":
http://www.oreilly.com/openbook/utp/
It discusses many fundemental questions that I often see posted here.
Cheers,
Keith

tm::resourceable
TM::ResourceAble(3pm) User Contributed Perl Documentation TM::ResourceAble(3pm)
NAME
TM::ResourceAble - Topic Maps, abstract trait for resource-backed Topic Maps
SYNOPSIS
package MyNiftyMap;
use TM;
use base qw(TM);
use Class::Trait ('TM::ResourceAble');
1;
my $tm = new MyNiftyMap;
$tm->url ('http://nirvana/');
warn $tm->mtime;
# or at runtime even:
use TM;
Class::Trait->apply ('TM', qw(TM::ResourceAble));
my $tm = new TM;
warn $tm->mtime;
DESCRIPTION
This traits adds methods to provide the role resource to a map. That allows a map to be associated with a resource which is addressed by a
URL (actually a URI for that matter).
Predefined URIs
The following resources, actually their URIs are predefined:
"io:stdin"
Symbolizes the UNIX STDIN file descriptor. The resource is all text content coming from this file.
"io:stdout"
Symbolizes the UNIX STDOUT file descriptor.
"null:"
Symbolizes a resource which never delivers any content and which can consume any content silently (like "/dev/null" under UNIX).
Predefined URI Methods
"inline"
An inlined resource is a resource which contains all content as part of the URI. Currently the TM content is to be written in AsTMa=.
Example:
inlined:donald (duck)
INTERFACE
Methods
url $url = $tm->url
$tm->url ($url)
Once an object of this class is instantiated it keeps the URL of the resource to which it is associated. With this method you can
retrieve and set that. No special further action is taken otherwise.
mtime
$time = $tm->mtime
This function returns the UNIX time when the resource has been modified last. 0 is returned if the result cannot be determined. All
methods from LWP are supported.
Special resources are treated as follows:
"null:"
always has mtime 0
"io:stdin"
always has an mtime 1 second in the future. The idea is that STDIN always has new content.
"io:stdout"
always has mtime 0. The idea is that STDOUT never changes by itself.
