Summary:
In deviantART.com site, a deviant is just a member of the site,
and to watch somebody is to get notifications of their activity (a bit like RSS).
My script adds an icon in the deviant's pages if they watch you.
Description:
If the deviant you visit (in his/her profile page, gallery or deviation) is watching you,
this script adds on the right of the deviant name in the title bar a watch icon,
so you can check this at a glance.
Also adds in the profile (main) page a line above the <i>Watch this deviant/Watching this deviant</i> one.
Both can be deactivated, by changing in the script the lines below those starting with <code>//$$</code>
Read these comments for instructions.
The message can be changed too. Also the icon, but it is slighly harder...
If you have no watchers, well this script will do nothing...
If you have some watchers, when you go to your main page, you will see in the <i>Recent Watchers</i>
box, on the right of the title, a new <i>Update watcher list</i> button.
If you have 20 watchers or less, just click this button, and you are done: go visit some of
your watchers, and see the magic works!
If you have more than 20 watchers, you have a <i>Complete List</i> link: click on it, a window listing
the first 200 watchers (or less if, like me, you are an ordinary deviant...) appears, as usual.
Hit the End key and you go at the bottom of the page. Here, you have a checkbox and a button
added by the script, below the navigation box.
For the first time, just hit the <i>Update watcher list</i> button. If you have 200 watchers or less,
you are already done, close the window. Above this number, the script will load the next page in the window.
Just let it work through all the pages of watchers you have. At the end, like in other cases,
a message box will display the total number of watchers found, confirming the end of the process.
Note: if you have a large number of watchers, like 20,000 to 50,000, the capture of the deviants
can take a long time... You can even minimize this window and see the page numbers going in the title...
But sometime deviantART doesn't like these repeated requests and returns an error page.
Or you closed the window, tired of waiting. Etc.
For these cases, there is a recovery/resume mechanism: go to the Complete List (first page),
and click the <i>Update watcher list</i> button: the watcher capture will resume were it was.
I was able to capture the 32,138 watchers of a deviant after many restarts...
What about new deviants?
If you have less than 20 new watchers, just click on the <i>Update watcher list</i> button in your
profile page. The script will get the new names in this page and update your list.
If you are very popular or away for a long time, with more than 20 new watchers,
click the <i>Complete List</i> link and in the Friends page, click the <i>Update watcher list</i>
button. The page will be scanned. If the last deviant wasn't in the list, it is likely there are
more, so the script will continue on the next page, until it finds a page full of known deviants.
If, for some reason, you prefer to regenerate fully the list (eg. to handle deviants no
longer watching you), check the <i>Rescan all</i> check box and the script will clear the list and
fill it again from scratch.
Note: the script doesn't handle automatically deviants no longer watching you: you have to rescan the
list to get rid of them.
Where does this list of watchers go?
I store it using the function GM_setValue. Greasemonkey puts these values in the user settings.
You can view these settings by typing <code>about:config</code> (and Enter) in the address bar of Firefox.
You can locate the settings of my scripts by typing <code>phi.lho</code> in the filter area:
you will see GM creates the keys <code>greasemonkey.scriptvals.http://Phi.Lho.free.fr//deviantART - Watching you?.xxx</code>
You can even edit them or copy them... Or erase their content.
These settings are stored in <code>C:\Documents and Settings\<Windows user name>\Application Data\Mozilla\Firefox\Profiles\<some profile code>.default\prefs.js</code>.
Path to user data (<code>C:\Documents and Settings</code>) might have been changed.
Note that this file seems to be written only when Firefox is stopped.
Technical notes:
I chose this way over cookies for convenience of examination and ease of use, plus you can't delete
it by accident if cleaning up your cookies...
As for the capacity, I have read that more than 32MB can be written without problem, which should be
more than enough, even for the most popular deviants!
Performance depends on your computer, of course.
Also why I do redirections instead of using GM_xmltttpRequest? Because the later is asynchonous,
which is fine for getting one piece of data only, but annoying for sequential processing
of several pages.
And I found no good way to convert the HTML text to a document able to run an XPath request,
and I didn't wanted to give up this nice capability...
Loading pages has the interesting side effect of letting the Dom processing the request.
And it also provides a nice visual feedback of the long operation...

// File/Project history:
1.03.005 -- 2008/06/26 (PL) -- Fixed for dA v.5! (watcher list)
1.03.004 -- 2008/06/02 (PL) -- Fixed for dA v.6, should work in both versions.
1.03.003 -- 2008/05/29 (PL) -- Fixed a bug in the previous change: problem with case...
1.03.002 -- 2008/05/10 (PL) -- Don't display scan button if not your watcher list.
1.03.001 -- 2008/03/13 (PL) -- Remove parameters from URL because MC has ?loggedin=1 n times...
1.03.000 -- 2008/02/14 (PL) -- Added button in Message Center to add new watchers.
Also renamed the file & script.
1.02.000 -- 2007/11/12 (PL) -- Change icon, manage multiple accounts.
1.01.000 -- 2007/11/09 (PL) -- Automatic build of the list of watchers, on user request.
