Behave.js: A repository from bigspotteddog

There is only one issue to resolve to add support for IE 7 and 8, read about it here and see if you can help

What?

Behave.js is a lightweight library for adding IDE style behaviors to plain text areas, making it much more enjoyable to write code in.

No Dependencies
Hard and Soft Tabs
Auto Open/Close Paranthesis, Brackets, Braces, Double and Single Quotes
Auto delete a paired character
Overwrite a paired character
Multi-line Indentation/Unindentation
Automatic Indentation

Usage

var editor = new Behave({
    textarea: document.getElementById('myTextarea')
});

Defaults and Options

var editor = new Behave({
    textarea: null,
    replaceTab: true,
    softTabs: true,
    softTabSize: 4,
    autoOpen: true,
    overwrite: true,
    autoStrip: true,
    autoIndent: true
});

textarea : Textarea element to apply the behaviors to
replaceTab : If set to true, replaceTab does three different things:
- Pressing the tab key will insert a tab instead of cycle input focus.
- If you are holding shift, and there is a full tab before your cursor (whatever your tab may be), it will unindent.
- If you have a range selected, both of the above rules will apply to all lines selected (multi-line indent/unindent)
softTabs : If set to true, spaces will be used instead of a tab character
softTabSize : If softTabs is set to true, the number of spaces used is defined here
autoOpen : If any of the following characters are typed, their counterparts are automatically added:
- ( adds )
- { adds }
- [ adds ]
- " adds "
- ' adds '
overwrite : If you type a closing character directly before an identical character, it will overwrite it instead of adding it. Best used with autoOpen set to true
autoStrip : If set to true, and your cursor is between two paired characters, pressing backspace will delete both instead of just the first
autoIndent : If set to true, automatic indentation of your code will be attempted. Best used with autoOpen set to true

Methods

editor.destroy();

destroy : Removes all event listeners from your textarea

ToDo

Add support for IE
Add multi-line indentation
