|
|
* ## Textarea transformation extension
|
|
*
|
|
* Transforms HTML textarea elements into fully-featured Ace editor instances while maintaining form compatibility
|
|
* and providing an interactive settings panel. Handles automatic resizing, form submission integration, and
|
|
* preserves the original textarea's styling properties. Includes a visual settings interface for configuring
|
|
* editor options like themes, modes, keybindings, and display preferences through an overlay panel.
|
|
*
|
|
* **Usage:**
|
|
* ```javascript
|
|
* var ace = require("ace/ext/textarea");
|
|
* var editor = ace.transformTextarea(textareaElement, {
|
|
* mode: "javascript",
|
|
* theme: "monokai",
|
|
* wrap: true
|
|
* });
|
|
* ```

* @module
