XTM::Path is a Perl module with topic map management, XPath like retrieval and construction facility.

SYNOPSIS

use XTM::XML;
$tm = new XTM (tie => new XTM::XML (file => mymap.tm)); # binds variable to channel

use XTM::Path;
my $xtmp = new XTM::Path (default => $tm);

# find particular topics and print topic id
foreach my $t ($xtmp->find (/topic[.//baseNameString/text() = "test"])) {
print $t->id;
}

# same using find twice
foreach my $t ($xtmp->find (/topic[.//baseNameString/text() = "test"])) {
print $xtmp->find (@id, $t);
}

# create a topic
$t = $xtmp->create (topic[@id = "id0815"]);
# same but with baseName
$t = $xtmp->create (topic[@id = "id0815"]/baseNameString[text() = "test"]);
# associations are always cumbersome
$a = $xtmp->create (association[member
[roleSpec/topicRef/@href = "#role1"]
[topicRef/@href = "#player1"]]
[member
[roleSpec/topicRef/@href = "#role2"]
[topicRef/@href = "#player2"]]);

This class provides a simple way to drill down the XTM data structures by following an XPath like approach.

The XTM standard (http://www.topicmaps.org/xtm/) is used as the basis to formulate XTM-Path queries. To find a particular topic, for instance, you might use
/topic[.//baseNameString = "some name"]

It is important to note that this package will NOT work on the original XTM document (this might even not exist if the map is created via other means), but is instead using the XTM::base data structure. This implies that all querying is done after merging and consolidation has been done.

Obviously, XTM::Path cannot be a complete query language, but it is useful in many development situations where drilling down the data structure is a cumbersome exercise. Together with intelligent add methods in XTM::Memory and XTM::generic this should simplify drastically the access, creation and manipulation of XTM data structures.

File::Path is a Perl module to create or remove directory trees.

SYNOPSIS

use File::Path;

mkpath([/foo/bar/baz, blurfl/quux], 1, 0711);
rmtree([foo/bar/baz, blurfl/quux], 1, 1);

The mkpath function provides a convenient way to create directories, even if your mkdir kernel call wont create more than one level of directory at a time. mkpath takes three arguments:

the name of the path to create, or a reference to a list of paths to create,
a boolean value, which if TRUE will cause mkpath to print the name of each directory as it is created (defaults to FALSE), and
the numeric mode to use when creating the directories (defaults to 0777), to be modified by the current umask.
It returns a list of all directories (including intermediates, determined using the Unix / separator) created.
If a system error prevents a directory from being created, then the mkpath function throws a fatal error with Carp::croak. This error can be trapped with an eval block:

eval { mkpath($dir) };
if ($@) {
print "Couldnt create $dir: $@";
}

Similarly, the rmtree function provides a convenient way to delete a subtree from the directory structure, much like the Unix command rm -r. rmtree takes three arguments:

the root of the subtree to delete, or a reference to a list of roots. All of the files and directories below each root, as well as the roots themselves, will be deleted.
a boolean value, which if TRUE will cause rmtree to print a message each time it examines a file, giving the name of the file, and indicating whether its using rmdir or unlink to remove it, or that its skipping it. (defaults to FALSE)
a boolean value, which if TRUE will cause rmtree to skip any files to which you do not have delete access (if running under VMS) or write access (if running under another OS). This will change in the future when a criterion for delete permission under OSs other than VMS is settled. (defaults to FALSE)
It returns the number of files successfully deleted. Symlinks are simply deleted and not followed.

NOTE: There are race conditions internal to the implementation of rmtree making it unsafe to use on directory trees which may be altered or moved while rmtree is running, and in particular on any directory trees with any path components or subdirectories potentially writable by untrusted users.

Additionally, if the third parameter is not TRUE and rmtree is interrupted, it may leave files and directories with permissions altered to allow deletion (and older versions of this module would even set files and directories to world-read/writable!)

Note also that the occurrence of errors in rmtree can be determined only by trapping diagnostic messages using $SIG{__WARN__}; it is not apparent from the return value.

Path::Abstract is a fast and featurefull class for UNIX-style path manipulation.

Geo::Google::Path is a path, by automobile, between two loci.

SYNOPSIS

use Geo::Google::Path;
# you shouldnt need to construct these yourself,
# have a Geo::Google object do it for you.

Google Maps is able to serve up directions between two points. Directions consist of two types of components:

1. a series of points along a "polyline".
2. a series of annotations, each of which applies to a contiguous
range of points.

In the Geo::Google object model, directions are available by calling path() on a Geo::Google instance. The return value is a Geo::Google::Path object, which is a composite of Geo::Google::Segment objects, which are in turn composites of Geo::Google::Location objects.

Extended Path Index provides an extended index type based on the Zope index type that has additional query methods that are especially suited to generating navigation trees, site maps - and also supports querying a single folder, something the standard PathIndex cant do.
Note: You normally dont need to install this separately, as it ships as a standard part of Plone 2.1 and up. This download is for people wanting to use it outside of Plone or in earlier releases of Plone.
This index supports depth limiting, and the ability to build a structure usable for navtrees and sitemaps. The actual navtree implementations are not (and should not) be in this Product, this is the index implementation only.
Main features:
- Can construct a site map with a single catalog query
- Can construct a navigation tree with a single catalog query
- Doesnt wake up any objects
- Much lower RAM consumption
- Massively improved performance
- Catalog based instead of traversal based
Works with:
- Plone 2.5.1
- Plone 2.5
- Plone 2.1.4
- Plone 2.1.3
- Plone 2.1.2
- Plone 2.1.1
- Plone 2.1
Enhancements:
- A minor release for Plone 2.5.1

Copy file or directory path is a service menu that can copy the full path of file or directory to klipper.

Snow Path Formation Simulator is a program that models the process of people forming very distinct, and yet not always altogether logical looking, paths in the snow as they walk across open spaces.

The evolving condition of the snow is displayed graphically. This project may eventually mature into a screensaver.
