/* Why? */

I wanted to detect the platform which visitors use 32-bit or 64-bit using JavaScript on various browsers, for dynamically changing download URL of the new TortoiseHg 1.0 installers. Unfortunately, I couldn’t achieve that goal, but I’d like to put my result for future reference.

/* How does it work ? */

Using this greasemonkey script, you can manage your favorites with “FavSet” (likes “Set” or “Category”) on Flickr.

In Flickr, the user can put star mark “Favorite” on a photo taken by other peoples. However, it’s difficult to look for favorite one since we have a lot of favorite photos. So I created this.

/* $hという関数を作ってみた */

のがことの発端なのです。
$hはオプジェクトが指定した複数のプロパティを全て持っているかテストするユーティリティ関数で、データのバリデーションに使っています。
これが$hのコード：

function $h(obj, props){
    return props.every(function(prop){
        return obj.hasOwnProperty(prop);
    });
}

見たまんま、とてもシンプルです。

/* How does it work ? */

This script applies patch that improves behavior of categories list on page scrolling in NicoVideo’s ranking page.

Recently, NicoVideo development team added new feature. Unfortunately, this feature is not good on Firefox. Well, I found description about this in development team blog: ‘works good in Safari’. So I have try and check on Safari for Windows, and it works very smoothly.
So I decide to create this patch.

/* RTM keyconfig */

I’ve updated RTM config for Firefox 3 + Greasemonkey 0.8.
There is no change of user confg and feature.

rtm_keyconfig.user.js [userscript.org]

/* Causes */

In previous version (0.1.2), It generates the code from user config, makes function (global scope) object and registers it into event handler of EventManager class. However, This code occurs some errors. So I can’t fix this issue.

EventManager.prototype.bodyKeyPressHandler = new Function("ev", "ignoreCombo", newcode);

Recently, I pinpointed the causes that “new Function(…)” occurs error. Therefore, I decide to insert script tag include generated code from user config into html. Like this:

var script = document.createElement('SCRIPT');
script.innerHTML = 'function gm_rtm_keyconfig(ev, ignoreCombo){n' + newcode + 'n}';
document.getElementById('content').appendChild(script);
eventMgr.bodyKeyPressHandler = function(ev, ignoreCombo){
    gm_rtm_keyconfig.call(eventMgr, ev, ignoreCombo);
};

/* Conclusion */

Thank you Ofer.
I can’t fix this issue without your comment.

enjoy RTM!
