Hack 76. Take a Walk on the Lighter Side

Gmail with grace from any web browser, whether
JavaScript-disabled, not yet supported, text-only, or on a PDA or
mobile phone .

Being a child of Google, Gmail hides all of its complexity behind a
rich, deep, feature-packed yet user-friendly web mail interface,
assuming you have the right browserone of recent
vintagefor the job. But what to do if your IT department
hasn't upgraded your version of the Internet
Explorer browser since Windows 95, you're quite
happy with the text-only Lynx browser, you're
running the latest nightly build of browser XYZ, which Gmail simply
doesn't like, or you're trying to
reach your mail from a PDA or smartphone?

Gmail-lite (home page: http://sourceforge.net/projects/gmail-lite,
SourceForge project page: http://sourceforge.net/projects/gmail-lite;
GNU Public License), as the name suggests, puts a
plain HTML face on Gmail. It is a PHP application that proxies your
interactions with Gmail, allowing you to surf using whatever browser
you have at hand or just plain prefer just plain prefer, while
keeping Gmail happy with its end of the conversation.

The authors of gmail-lite have done a fantastic job, affording you a
plain HTML interface to just about every bit of functionality Gmail
provides through its more interactive JavaScript-based frontend.

6.9.1. Installing the Hack

You have to marvel at the wonders of PHP-based applications and their
simple installation. Assuming you have the prerequisites taken care
of, it's just a matter of downloading, unpacking,
and enjoying. I installed gmail-lite both on my local Mac OS X laptop
and under my hosted ISP account in seconds each.

Gmail-lite assumes you have PHP installed on a web server. It relies upon the libgmailer library (http://gmail-lite.sourceforge.net), included for your convenience in the gmail-lite distribution. You also need the curl library (http://www.php.net/curl) with SSL support (http://www.openssl.org) since gmail-lite always talks to Gmail over a secure channel.

Download gmail-lite (http://sourceforge.net/projects/gmail-lite)
and unpack the distribution (0.56 at the time of this writing, but
yours is sure to be a later version) somewhere under your web
server's document root, where the rest of your web
site lives (ask your system administrator or service provider if
you're not sure where this is):

$ tar -xvzf gmail-lite-
0.56  
.tar.gz 
gmail-lite-0.56/
gmail-lite-0.56/compose.php
gmail-lite-0.56/config.php
gmail-lite-0.56/debug.php
gmail-lite-0.56/diagnose.php
gmail-lite-0.56/dl.php
gmail-lite-0.56/docsl
gmail-lite-0.56/index.php
gmail-lite-0.56/INSTALL
gmail-lite-0.56/libgmailer.php
gmail-lite-0.56/logout.php
gmail-lite-0.56/main.php
gmail-lite-0.56/star.gif
$ mv gmail-lite-0.56 
gmail-lite  

That last command simply renames the directory to something that will be a little friendlier and easier to remember when it comes to visiting in my browser.

To verify that everything went to plan, point your web browser at

diagnose.php using the URL corresponding to the
gmail-lite directory on your web
sitee.g.,

http://www.example.com/~rael/gmail-lite/diagnose.php
The resulting page should look like Figure 6-18.

If diagnose.php does indicate that
something's gone wrong, consult the installation and
troubleshooting documentation in the INSTALL
text file in your gmail-lite folder.

6.9.2. Running the Hack

Point your computer's web browser at the URL
corresponding to the gmail-mobile directory on
your web sitee.g.,

http://www.example.com/~rael/gmail-lite (or just
click the "Press here..." link on
the diagnose.php page).

Depending on your setup, you may actually need to tack /index.php on to that URL, but most PHP-enabled servers know to look for and serve up index.php as a default when no filename is specified and there's no static indexl in sight. The gmail-lite package includes just such an index.php file.

Figure 6-19 shows the plain HTML login screen as it
will appear in a typical browser window. Enter your Gmail login
(e.g.,
username@gmail.com) and
password, alter the time zone if you feel so inclined, and click the
"sign-in" button.

You're greeted with a summary page with links to
your Gmail Inbox, Sent, Trash, and Spam folders, Starred messages,
and personal labelsshown in Figure 6-20 as it

Click the Inbox link and you'll be presented with a
simple list of your incoming messages, as shown

on a Pocket PC in Figure 6-21. At the top is a quick-link toolbar and
pull-down menus for switching views, exploring labeled mail, and
searching your Gmail messages ["Gmail Search
Syntax" earlier in this chapter]. (Click the Get
button after making your selections or entering a search query.) At
the bottom are actions you can apply to any number of checked
messages (check the associated checkbox to the right of a message
subject to act upon it), including archive/unarchive, label,
star/unstar, mark as read/unread, mark/unmark as spam, and
trash/untrash. (Click the Do button to apply any action.)

Select any email message to open it. Figure 6-22
shows a typical email message viewed

in the text-only Lynx
browser. The layout of individual message pages is much like that of
the Inbox (or any folder) view. As you can see in the figure,
I'm about to take a look at all my
"foo"-labeled messages.

So, there you have it: a plain old HTML interface to about anything
you can do through Gmail proper. (In all likelihood, by the time you
read this, Gmail will have built its own plain HTML version without
all the browser and JavaScript requirements. Still, this is a great
hack and worth fiddling about with.)

The gmail-lite author does caution that "GMail is a still in beta, and GMailer (along with gmail-lite) is, I would say, an `alpha hack' of a beta software. So don't expect it to work all the time, and do not build critical mission applications upon it" (http://gmail-lite.sourceforge.net/).
