CodeEditor

Since 2.2.1

The editor applies language-specific highlighting and keeps independent scrollable documents.

CodeEditor extends TextArea and adds syntax highlighting, code folding, and editor-quality keyboard shortcuts. It uses the built-in JetBrains Mono Bold font by default.

Additional shortcuts over TextArea:

Shortcut	Action
Tab	Inserts two spaces at the cursor.
Ctrl+/	Toggles // line comments on the current line or selection.
Enter	Inserts a new line and preserves the leading indentation of the previous line.

Everything from TextArea (styles, value binding, validators, scrollers, etc.) applies here too.

INFO

Everything documented on UIElement (layout, styles, events, data bindings, etc.) applies here too.

Usage

var editor = new CodeEditor();
editor.setLanguage(Languages.JSON);
editor.setValue(new String[] { "{", "  \"key\": \"value\"", "}" }, false);
editor.setLinesResponder(lines -> System.out.println(String.join("\n", lines)));
parent.addChild(editor);

codeEditor({
    language(Languages.JSON)
    layout = { width(300.px); height(200.px) }
}) { }

let editor = new CodeEditor();
editor.setLanguage(Languages.JSON);
editor.setValue(["{", "  \"key\": \"value\"", "}"], false);
parent.addChild(editor);
