keyconfig 20110522

[dorando]

A couple of hours ago (at most a few days ago) I noticed a change on GOOGLE: the following (for opening individual GOOGLE search results in a new (and/or the current) tab) doesn't seem to work anymore, the "nodes" must have changed slightly:

Code: Select all

if(window.content.location.href.match(/^http(s)?://www.google.(com|fr)/search/))
{
var nodes = content.document.evaluate('//h3/a[@class]', content.document, null, 7, null);
gBrowser.addTab(nodes.snapshotItem(0));
} 

The (10 standard) links (in GOOGLE) seem to have this

Code: Select all

<h3 class="r" style="display: inline;"> 

around them, but simply (naively) replacing "a" with "r" (in the keyconfig code above) didn't do the trick...

Any pointers how to fix the code?

Try

Code: Select all

var nodes = content.document.querySelectorAll("h3.r a, h3 a.l");
gBrowser.addTab(nodes[0]); 

Arrow Up:

Code: Select all

if(commandDispatcher.focusedWindow.document.designMode == "on")
 goDoCommand("cmd_lineNext");

var target = commandDispatcher.focusedElement;
if(!(target instanceof HTMLInputElement && (target.type == "text" || target.type == "password")))
 commandDispatcher.focusedWindow.scrollByLines(-4); 

The problem is that certain webmail interfaces are having problems with this - whereby the up arrow key acts like the down arrow key.

Try

Code: Select all

if(commandDispatcher.focusedWindow.document.designMode == "on")
 goDoCommand("cmd_linePrevious");

var target = commandDispatcher.focusedElement;
if(!(target instanceof HTMLInputElement && (target.type == "text" || target.type == "password")))
 commandDispatcher.focusedWindow.scrollByLines(-4);

Thanks, Dorando! That fixed it perfectly!

dorando, trying to install keyconfig for Linux Thunderbird 17.x using the build in mechanism fails:



Any idea why that might be?

[Brummelchen]

its not listed = not present on AMO - such simple
only here http://mozilla.dorando.at/

@Rava, here's how to install keyconfig on Thunderbird.

In the Browser: Context Menu > Save Link As…
In Thunderbird: Tools > Add-ons > Button next to the Search box > Install Add-on From File…

You can also drag keyconfig.xpi link from Firefox window onto Add-ons Manager in Thunderbird window.

can you tell me please the code for 'open link in background tab' ?
I need to click on a link with CTRL+SHIFT held down and open that link in the background

I just wanted to thank you for this fabulous add-on, which still works impressively well with Firefox 20!

It's hard to believe FF includes no native way to enable-disable its built-in keyboard shortcuts (which are often presumptuously inconvenient, such as using the traditional text-editing keys Ctrl+I and Ctrl+B for Bookmark-related tasks).

It's also hard to believe that FF's add-on site doesn't seem to host any third-party code that lets you do it, including Keyconfig. (Have you submitted it there? Did they turn you down for some reason? Go figure.)

Anyway, a grateful sigh of relief here. Cheers, Ander

For focused links try

Code: Select all

if(commandDispatcher.focusedElement && commandDispatcher.focusedElement.href)
 openLinkIn(commandDispatcher.focusedElement.href, "tab", { inBackground: true }); 

, for hovered links try

Code: Select all

if(XULBrowserWindow.overLink)
 openLinkIn(XULBrowserWindow.overLink, "tab", { inBackground: true }); 

Have you submitted it there?

No.

Is it possible to get the size of the image (in kb, not dimensions) by it's ID?

Is it possible to get the size of the image (in kb, not dimensions) by it's ID?

Try this:

Code: Select all

function formatNumber(number) {
  return (+number).toLocaleString();
}
var cacheService = Components.classes["@mozilla.org/network/cache-service;1"].
  getService(Components.interfaces.nsICacheService);
var httpCacheSession = cacheService.createSession("HTTP", 0, true);
httpCacheSession.doomEntriesIfExpired = false;
var image = content.document.getElementsByTagName("img")[0];
// var image = content.document.getElementById("thingamajig");
var url = image.src;
var cacheKey = url.replace(/#.*$/, "");
try {
  var cacheEntryDescriptor = httpCacheSession.openCacheEntry(cacheKey,
    Components.interfaces.nsICache.ACCESS_READ, false);
  var imageSize = cacheEntryDescriptor.dataSize;
  var kbSize = Math.round(imageSize / 1024 * 100) / 100;
  alert(formatNumber(kbSize) + " KB (" + formatNumber(imageSize) + " bytes)");
} catch (e) {
  alert("Unknown (not cached)");
}

morat,
It doesn't work for me... I persistently get an alert "Unknown (not cached)"

The openCacheEntry method now fails if it is called on the main thread.

Code: Select all

function openCacheEntry(key, cb) {
  var tries = 0;
  var listener = {
    onCacheEntryAvailable: function (entry, access, status) {
      if (entry || tries == 1) {
        cb(entry);
      } else {
        tries++;
        ftpCacheSession.asyncOpenCacheEntry(key, ACCESS_READ, this, true);
      }
    }
  }
  httpCacheSession.asyncOpenCacheEntry(key, ACCESS_READ, listener, true);
}
function formatNumber(number) {
  return (+number).toLocaleString();
}
var ACCESS_READ = Components.interfaces.nsICache.ACCESS_READ;
var cacheService = Components.classes["@mozilla.org/network/cache-service;1"].
  getService(Components.interfaces.nsICacheService);
var httpCacheSession = cacheService.createSession("HTTP", 0, true);
httpCacheSession.doomEntriesIfExpired = false;
var ftpCacheSession = cacheService.createSession("FTP", 0, true);
ftpCacheSession.doomEntriesIfExpired = false;
var image = content.document.getElementsByTagName("img")[0];
// var image = content.document.getElementById("thingamajig");
var url = image.src;
var cacheKey = url.replace(/#.*$/, "");
openCacheEntry(cacheKey, function (cacheEntry) {
  if (cacheEntry) {
    var imageSize = cacheEntry.dataSize;
    var kbSize = Math.round(imageSize / 1024 * 100) / 100;
    alert(formatNumber(kbSize) + " KB (" + formatNumber(imageSize) + " bytes)");
  } else {
    alert("Unknown (not cached)");
  }
});

Almost ALL add-ons on addons.mozilla.org ARE third party.
