### 编辑器指定行高亮

```javascript
 this.editor.deltaDecorations(
        this.editor.getModel().getAllDecorations(),
        [{
            range: new monaco.Range(
              conflictBlock.right_start,
              0,
              conflictBlock.right_end,
              0
            ),
            options: {
              isWholeLine: true,
              className: 'rightLineDecoration',
              marginClassName: 'rightLineDecoration'
            }
          }]
      )
```

```css
.rightLineDecoration {
  background-color: red;
}
```

### 清除编辑器行高亮样式

```
let ids = [];
let decorations = this.editor.getModel().getAllDecorations();
for (let decoration of decorations) {
	if (
		decoration &&
		decoration.options &&
		decoration.options.className === "code-light-line"
	) {
		ids.push(decoration.id);
	}
}
if (ids && ids.length) {
	this.editor.deltaDecorations(ids, []);
}
```

	display: none !important;
}
```

### 设置焦点

```javascript
this.editor.focus()
```

- 参考：https://github.com/atularen/ngx-monaco-editor/issues/110

### 设置焦点到末尾

```javascript
let lineNumber = this.editor.getModel().getLineCount();
let column = this.editor.getModel().getLineMaxColumn(lineNumber);
this.editor.setPosition({
	column: column,
	lineNumber: lineNumber,
});
```
