Safari.Oreilly.com
I love safari.oreilly.com, but hate having to hunt for the next/prev section button with my mouse (especially because i have a trackpad). Here's a small kludge to go to the next or previous page via the keyboard. on my powerbook, i prefer shift+right/left arrow for one-handed navigation, but you can use whatever combination you'd like.
// ==UserScript==
// @name Next and Previous Keyboard Shortcuts

function navi(e){
function gogo(str){
m = find(str+" section link")
if(m.hasMatch)
go(m.element.href)
}
kc = e.keyCode
if(e.shiftKey && kc == 39) //rt arrow
gogo("next")
if(e.shiftKey && kc == 37) //lt arrow
gogo("previous")
}
window.addEventListener("keypress", navi, true)

MediaWiki
[edit]
Save & continue
MediaWiki is a great piece of software, but when you're editing a wiki page (like this one), you can't click Save without losing your place in the edit box. That's a problem if you like to save reflexively.
This script fixes the problem by adding a "Save & continue" button to any MediaWiki edit page, which saves the page and then returns to the edit page again, restoring your scroll position and selection exactly where they were.
It also grabs Ctrl-S as a keyboard shortcut for the Save & continue functionality (but only while you're at the edit page).
// ==UserScript==
// @name Save and Continue
// @when Pages Match
// @description inserts a save and continue button to any mediawiki edit page
// @include http://groups.csail.mit.edu/uid/chickenfoot/scripts/index.php/*
// ==/UserScript==
// WikiSave trigger
// Assign this trigger to *action=edit* to make it
// fire on all MediaWiki edit pages (but possibly
// other pages too), or limit it to your favorite
// MediaWikis, e.g. http://groups.csail.mit.edu/uid/chickenfoot/scripts/*action=edit*
// Save this Wiki edit page, then come back to it
function wikiSave() {
var editPage = document.location.toString()
var textbox = find("textbox").element;
var editState = saveTextboxState(textbox)
click("save page button")
whenLoaded(function() {
go(editPage)
var textbox = find("textbox").element;
textbox.focus();
restoreTextboxState(textbox, editState);
})
}
// Saves a textbox's scroll and selection positions
function saveTextboxState(/*Node*/ tbox) {
return {
scrollTop : tbox.scrollTop,
scrollLeft : tbox.scrollLeft,
selectionStart : tbox.selectionStart,
selectionEnd : tbox.selectionEnd
};
}
// Restores a textbox's scroll and selection positions
function restoreTextboxState(/*Node*/ tbox, /*State*/ state) {
tbox.scrollTop = state.scrollTop;
tbox.scrollLeft = state.scrollLeft;
tbox.selectionStart = state.selectionStart;
tbox.selectionEnd = state.selectionEnd;
}
// inject Save & continue button
var b = new Button("Save & continue", wikiSave)
insert(after("save page button"), b)
// attach keyboard shortcut (Ctrl-S)
window.addEventListener("keypress", function(event) {
if (event.ctrlKey && event.charCode == 's'.charCodeAt(0)) {
wikiSave();
event.preventDefault();
}
}, true)
// use this with trigger */index.php/* to get a history
// of the last wiki pages of a MediaWiki site
[edit]
MediaWiki navigation history
When moving around or creating new pages in MediaWiki, there is the problem that you cannot easily use the back button after having edited and saved a page, because this will bring you back to the editor and not to the page where you were before.
So, the following trigger script will take the last 6 visited wiki pages from your browser history and add them below the main navigation in a new box on the left site of the screen. It's best to set the trigger to something like */index.php/* or */wiki/*.
// ==UserScript==
// @name MediaWiki navigation history
// @when Pages Match
// @description adds new box on screen of last 6 visited wiki pages from browser history
// @include */index.php/*
// @include */wiki/*
// ==/UserScript==
function hist() {
var MAX_ENTRIES = 6; //maximum number of history entries
var TITLE_TEXT = 'wiki history';
var WIKI_PATTERN = /\/index.php|\/wiki\//; //URL pattern part for MediaWiki pages
var item, prevTitle, itemCount=0, links='';
for( var i=history.length-2;i>=0; i-- ) {
item = history[i];
if (itemCount==MAX_ENTRIES)
break;
if (!item.match(WIKI_PATTERN))
break;
if (item.indexOf("action") > 0 || item.indexOf("Special:Userlogin") > 0 )
continue;
var title = item.replace( /.*\//,"" ).replace( /#.*/,"" ).replace( /_/g, " " );
if (title == prevTitle)
continue;
itemCount++;
links+='<li><a href="'+item+'">'+title+'</a><br></li>';
prevTitle = title;
}
if( itemCount>0 )
insert(before(document.getElementById("p-search")),
'<div class="portlet"><h5>'+TITLE_TEXT+'</h5><div class="pBody"><ul>'+links+'</ul></div></div>');
}
hist();

mit412.com
This was used as an example script in a presentation on Chickenfoot. The presentation was given to the MIT class 15.564 on May 10, 2006 by Jason Carver, Mark Grimm and Jason Witzberger. The script is a proof-of-concept price comparison, using the mit412.com and Barnes and Noble prices.
Nice additions might include:
- Looking at other sites and returning the lowest price overall
- Speed improvement by manually forming B&N search URL instead of go,enter,click
- dealing with comma-separated authors in mit412 (B&N tends to get pretty confused by them)
Current limitations include:
- does not work with the mit412.com frames! (Must open the lower frame's page directly)
- does not return precise price (only floored dollar amount, to which we add 1)
- blindly returns first B&N hit on search "(Book) by (Author)"
- Fails catastrophically on non-standard search results, or 0 results returned

6.001 Tutor
6.001 is the introductory programming course at MIT, which has a web-based tutor system. I used Chickenfoot to make several changes to the site's user interface.
// ==UserScript==
// @name 6.001 Tutor
// @when Pages Match
// @description modifies 6.001 online tutor's user interface
// @include http://sicp.csail.mit.edu/*
// ==/UserScript==
//First, I moved the login form to the top of the page:
// Move 6.001 login form to top of the page.
// Trigger assigned to http://sicp.csail.mit.edu/Spring-2007/
form = find("log in form").html;
insert(after("welcome to 6.001"), form)
//Chickenfoot really needs a move() command, or else remove() should return the chunk of page that it removed so that the chunk can be inserted //somewhere else.
//Second, I added a button that goes to a staff version of the tutor:
// Add button that jumps to staff tutor.
// Trigger assigned to http://sicp.csail.mit.edu/Spring-2007/
b = new Button("Staff Tutor", function() {
go("http://sicp.csail.mit.edu/Spring-2007/staff/");
pick("Staff");
setTimeout(function() { click("Log in"); }, 1);
});
insert(after("welcome to 6.001"), b);
//The setTimeout() call is a tricky hack, which gives Firefox a chance to autofill the username and password field of the staff login form before the //script clicks the Log In button. Without setTimeout, I'd have to put in enter() commands containing my username and password, too. (Note that //sleep() doesn't work properly here, unfortunately.)
//Third, the staff tutor has a complex form for generating reports. I added hyperlinks for the reports I use most frequently (the PS and Lecture //reports):
// Turn radio buttons into links on 6.001 report page.
// Assign trigger to https://sicp-s1.mit.edu/spring07/tutor.cgi
for (var m = find(/(PS|Lec) \d+/); m.hasMatch; m = m.next) {
addLink(m);
}
function addLink(m) {
var name = m.text; // e.g. "PS 1"
var link = new Link(name, function() {
find("form").element.reset()
pick(name);
click("submit");
});
replace(m, link);
}
//Basically this script finds "PS 1", "PS 2", etc., each of which is a label for a radiobutton. It then replaces each of those labels with a //hyperlink that selects the radio button and submits the form. A tricky bit here is that we have to reset the form, too, in order to get the result //we want. Chickenfoot probably needs a simple reset() command for this purpose.

CSAIL Member Resources page
This page (http://www.csail.mit.edu/resources/resources.html) that I use from time to time is very hard to scan for the link I want, because the links are displayed as URLs rather than as readable text. An example of the link format it uses is "Google - http://www.google.com". The script below finds all such links (using the simple keywords "http https") and puts the hyperlink around the text node preceding it instead (so the Google example would become simply "Google - (http://www.google.com)").
// ==UserScript==
// @name CSAIL Member Resources page
// @when Pages Match
// @description finds all links and puts the hyperlink around the text node preceding it instead
// @include http://www.csail.mit.edu/resources/resources.html
// ==/UserScript==
For good measure, the script also enlarges the link I use the most, to make it easier to find visually and easier to click on with the mouse.
// Fix weird hyperlinks and enlarge most useful link.
// Assign to trigger http://www.csail.mit.edu/resources/resources.html
for (m = find("http https link"); m.hasMatch; m = m.next) {
var link = m.element;
var text = link.previousSibling;
replace(text, "<a href='" + link + "'>" + text.nodeValue + "</a>");
remove(link);
}
mrbs = find("Book a CSAIL room link")
replace(mrbs, "<font size='+2'>" + mrbs.html + "</font>");

Spiegel Online
This script observes what you are looking at on Spiegel Online (http://www.spiegel.de), creates a simple interest profile, and adds a section with links to related articles near the top of each Spiegel page. It should be triggered on URLs matching http://www.spiegel.de/*.
I created the script to familiarize myself with Chickenfoot. It's not that useful on its own, but perhaps it will be helpful to Chickenfoot users who are going to create scripts providing related functionality.
