SYNOPSIS

Plenty of people have learned WWW::Mechanize, and now, you can too!
Following are user-supplied samples of WWW::Mechanize in action.

You can also look at the t/*.t files in the distribution.

Please note that these examples are not intended to do any specific task. For all I know, theyre no longer functional because the sites they hit have changed. Theyre here to give examples of how people have used WWW::Mechanize.

Note that the examples are in reverse order of my having received them, so the freshest examples are always at the top.

Starbucks Density Calculator, by Nat Torkington

Heres a pair of scripts from Nat Torkington, editor for OReilly Media and co-author of the Perl Cookbook.

Rael [Dornfest] discovered that you can easily find out how many Starbucks there are in an area by searching for "Starbucks". So I wrote a silly scraper for some old census data and came up with some Starbucks density figures. Theres no meaning to these numbers thanks to errors from using old census data coupled with false positives in Yahoo search (e.g., "Dodie Starbuck-Your Style Desgn" in Portland OR). But it was fun to waste a night on.

Here are the top twenty cities in descending order of population, with the amount of territory each Starbucks has. E.g., A New York NY Starbucks covers 1.7 square miles of ground.

New York, NY 1.7
Los Angeles, CA 1.2
Chicago, IL 1.0
Houston, TX 4.6
Philadelphia, PA 6.8
San Diego, CA 2.7
Detroit, MI 19.9
Dallas, TX 2.7
Phoenix, AZ 4.1
San Antonio, TX 12.3
San Jose, CA 1.1
Baltimore, MD 3.9
Indianapolis, IN 12.1
San Francisco, CA 0.5
Jacksonville, FL 39.9
Columbus, OH 7.3
Milwaukee, WI 5.1
Memphis, TN 15.1
Washington, DC 1.4
Boston, MA 0.5

Hardware::iButton is a Perl module that allows to talk to DalSemi iButtons via a DS2480 serial widget.

SYNOPSIS

use Hardware::iButton::Connection;
$c = new Hardware::iButton::Connection "/dev/ttyS0";
@b = $c->scan();
foreach $b (@b) {
print "family: ",$b->family(), "serial number: ", $b->serial(),"n";
print "id: ",$b->id(),"n"; # id = family . serial . crc
print "reg0: ",$b->readreg(0),"n";
}

This module talks to iButtons via the "active" serial interface (anything using the DS2480, including the DS1411k and the DS 9097U). It builds up a list of devices available, lets you read and write their registers, etc.

The connection object is an Hardware::iButton::Connection. The main user-visible purpose of it is to provide a list of Hardware::iButton::Device objects. These can be subclassed once their family codes are known to provide specialized methods unique to the capabilities of that device. Those devices will then be Hardware::iButton::Device::DS1920, etc.

iButtons and solder-mount Touch Memory devices are each identified with a unique 64-bit number. This is broken up into 8 bits of a "family code", which specifies the part number (and consequently the capabilities), then 48 bits of device ID (which Dallas insures is globally unique), then 8 bits of CRC. When you pass these IDs to and from this package, use hex strings like "0123456789ab".

DigiTemp uses a simple serial port adapter to read temperatures from the Dallas Semiconductor 1-Wire DS1820 digital temperature sensors.
DigiTemp supports the DS9097-U adapter, supports DS2409 based 1-Wire hubs, and features a 1-Wire walk that will display all devices on the LAN, not just temperature sensors.
Enhancements:
- This release combines all the binary releases into a single tar.gz, including Windows binaries compiled with Cygwin.
- It adds DS1923 Hygrochron support, and fixes some small bugs in the userial driver.
- A lockdev bug was fixed (wasnt unlocking when done).
- A crash in free_couplers() was fixed.
- There is better error reporting when trying to access serial ports that dont exist.
- This release is compiled for Windows with Cygwin.
- DS2490/9490 support still doesnt work well for the author, although others have had success with it.

jHomenet is a home automation application. jHomenet uses both X-10 and Dallas Semiconductor 1-Wire network sensors and devices to collect sensor data and control devices.
jHomenet project can be programmed to respond to events, including particular sensor data values or time-of-day events.
Enhancements:
- This is a binary only release that includes several changes.
- Most noticable is the change in the versioning format.
- This change, however, also includes a drastic change in the library versioning and dependency framework.
- Other changes include a revised EventLogger, some UI tweaks, and several new jhomenet-commons JUnit unit tests.
- Some significant changes were also made to the Ant build setup.
