The purpose of [[Greasemonkey]] is to manage user scripts.
var MESSAGES = [
[[User script]]s allow the ''user'' to control the way they use the web, by customizing it with scripting.
    'びゃああああああああああああああああああああ',
The [https://addons.mozilla.org/en-US/firefox/addon/greasemonkey/ Greasemonkey extension] won't do any good without any scripts installed.

// フッター
The first thing an eager user should do is find and install ''(or write!)'' a useful script.

var TIMER_INTERVAL = 1;


//====================================================================
Installation of a script is most often done by clicking a link on a web page.
// 以下も設定ですが、変更するとプログラムが壊れることがありますので
<!-- Not in 4.0
// あまり自信の無い方は変更しないようにしてください
One may also drag-and-drop a local file into the browser window, or optionally use the menu bar [http://support.mozilla.com/en-US/kb/Menu+Reference#Open_File_ File &rarr; Open File...] dialog to open it.
//====================================================================

When navigating to a URL which ends with <code>.user.js</code>, [[Greasemonkey]] will trigger the installation dialog.

//  timeline  タイムラインからリプライ
// ※(MESSAGE_COND == hello && POST_MODE != post) はエラーになります
var POST_MODE = 'reply';


// (MESSAGE_COND == hello) のとき挨拶か判定する関数
When navigating to a [[user script]], Greasemonkey will open its installation dialog instead of loading the script like a normal page.
// 適当なのでお好きに直してください
A thumbnail of this dialog is shown to the left.
function is_hello(text) {
It displays the name and description of the script as well as the [[include and exclude rules]] and special [[API]]s that apply.
    if (text.search(/^おは(?:や[ーう]|[よゆ]ー?)/) >= 0) {
<!-- Not in 4.0!
        return true;
''Note:'' Greasemonkey must be  [[Troubleshooting (Users)#Greasemonkey Enabled Status|enabled]] to install scripts.
    }
-->
    if (text.search(/^こんに?ち[はわ]/) >= 0) {
        return true;
    }
    if (text.search(/^(?:こん?ばん?[わみ]|こん?ば[やゆよ])/) >= 0) {

var MAX_REPLY_ID_SYNC_REBOOT = true;
Like the Firefox extension installation dialog, this button is disabled for a few seconds to avoid the same potential [http://www.squarefree.com/2004/07/01/race-conditions-in-security-dialogs security vulnerability].


// プレフィクス
;* The Cancel button
var PREFIX = ['twitter-bot-modoki', MESSAGE_COND, MESSAGE_MODE, POST_MODE, '']
This button will cancel the installation of a script.
            .join('-');


// 最後に投稿した時刻を保存するキー
<!-- Not in 4.0
var LAST_POSTED_KEY = PREFIX + 'last-posted';
;* The View Script Source button
This button will allow viewing of the source code contained in the script.
At this point, [[Greasemonkey]] has already downloaded the [[user script]] in question to display the name and other details.


// 排他制御用のシリアルを保存するキー
When a user shows the script source, it displays the temporary file that Greasemonkey has already downloaded depicted in this [[:media:View-source.png|screenshot]].
var POST_SERIAL_KEY = PREFIX + 'post-serial';
In this window there is an information bar at the top similar to the Firefox extension installation security warning.
Clicking the install button here will also install the script.


// 次に投稿する MESSAGES のインデクスを保存するキー
-->
var LAST_INDEX_KEY = PREFIX + 'last-index';
Now with some scripts installed, we can open the [[Greasemonkey Manual:Monkey Menu|Monkey Menu]] to list and manage them.

About User Scripts

The purpose of Greasemonkey is to manage user scripts. User scripts allow the user to control the way they use the web, by customizing it with scripting. The Greasemonkey extension won't do any good without any scripts installed.

The first thing an eager user should do is find and install (or write!) a useful script.

Installation of a script is most often done by clicking a link on a web page.

  • Any file that ends in .user.js is a user script.

When navigating to a URL which ends with .user.js, Greasemonkey will trigger the installation dialog. Note that Greasemonkey must be enabled to do so.

The Installation Dialog

GM Installation Dialog

When navigating to a user script, Greasemonkey will open its installation dialog instead of loading the script like a normal page. A thumbnail of this dialog is shown to the left. It displays the name and description of the script as well as the include and exclude rules and special APIs that apply.

  • The Install button

This button will, of course, install the script in question. Like the Firefox extension installation dialog, this button is disabled for a few seconds to avoid the same potential security vulnerability.

  • The Cancel button

This button will cancel the installation of a script.

Now with some scripts installed, we can open the Monkey Menu to list and manage them.
