/**
|
||
|
|
* # `monaco-editor`
|
||
|
|
* `monaco-editor` is a Polymer 2.0 element for [Monaco Editor](https://microsoft.github.io/monaco-editor/), a browser-based code editor which also powers Visual Studio Code.
|
||
|
|
* ## Installation
|
||
|
|
* ```
|
||
|
|
* bower install --save PolymerVis/monaco-editor
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* ## Documentation and demos
|
||
|
|
* More examples and documentation can be found at `monaco-editor` [webcomponents page](https://www.webcomponents.org/element/PolymerVis/monaco-editor).
|
||
|
|
*
|
||
|
|
* The demos can be found at the [`monaco-editor` Github page](https://PolymerVis.github.io/monaco-editor/build/demo).
|
||
|
|
*
|
||
|
|
* ## Special notes on styling and demo
|
||
|
|
* The layout of the hints are out for the demo because of the way the original monaco editor is styled and the way webcomponents.org renders the demo. It is very difficult for me to isolate the conflicts.
|
||
|
|
*
|
||
|
|
* ## Disclaimers
|
||
|
|
* PolymerVis is a personal project and is NOT in any way affliated with Microsoft, Polymer or Google.
|
||
|
|
*
|
||
|
|
* ## Quick start
|
||
|
|
* ```html
|
||
|
|
* <!-- enable code folding, minimap, and dark theme -->
|
||
|
|
* <monaco-editor
|
||
|
|
* folding
|
||
|
|
* minimap
|
||
|
|
* theme="vs-dark"
|
||
|
|
* language="javascript"></monaco-editor>
|
||
|
|
* ```
|
||
|
|
* Please look at the documentation for all the available options.
|
||
|
|
*
|
||
|
|
* ## Pre-populated with codes
|
||
|
|
* 1. Populate with the `value` property.
|
||
|
|
* ```js
|
||
|
|
* var codes = `// this is a comment line
|
||
|
|
* var helloworld = "hello world";
|
||
|
|
* `;
|
||
|
|
* ```
|
||
|
|
* ```html
|
||
|
|
* <!-- 2-way binding is available for `value` -->
|
||
|
|
* <monaco-editor
|
||
|
|
* language="javascript"
|
||
|
|
* value="{{codes}}"></monaco-editor>
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* 2. Populate with a `monaco-value` `slot` element.
|
||
|
|
* *Note that the `text` in the `slot` element is only loaded once during initialization. Subsequent changes to the slot will not change the `value`.*
|
||
|
|
* ```html
|
||
|
|
* <!-- text is only loaded once, and not updated upon subsequent changes -->
|
||
|
|
* <monaco-editor
|
||
|
|
* language="javascript"
|
||
|
|
* value="{{codes}}">
|
||
|
|
* <div slot="monaco-value">// comment line
|
||
|
|
* var helloworld = "hello world";</div>
|
||
|
|
* </monaco-editor>
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* ## Schemas for `monaco-editor`
|
||
|
|
* You can either define your `schemas` for `monaco-editor` to do hints and validation, or you can use the `monaco-schemas`.
|
||
|
|
*
|
||
|
|
* ```html
|
||
|
|
* <!-- extract `schemas` by definiting a space-separated string, `keys`. -->
|
||
|
|
* <monaco-schemas keys="vega-lite" schemas="{{schemas}}"></monaco-schemas>
|
||
|
|
*
|
||
|
|
* <!-- pass the `schemas` array to `json-schemas` and set `json-validate` flag
|
||
|
|
* to enable hints, suggestions, and validation of the inputs. -->
|
||
|
|
* <monaco-editor json-validate language="json"
|
||
|
|
* json-schemas="[[schemas]]"></monaco-editor>
|
||
|
|
*```
