Text Formatting

Termina supports common text formatting options for TextNode and StreamingTextNode.

Bold Text

new TextNode("Bold text").Bold()

Italic Text

new TextNode("Italic text").Italic()

Underlined Text

new TextNode("Underlined text").Underline()

Combining Styles

Styles can be chained together:

new TextNode("Bold and italic")
    .Bold()
    .Italic()

new TextNode("All styles")
    .Bold()
    .Italic()
    .Underline()
    .WithForeground(Color.Cyan)

Word Wrapping

Control how text handles long lines:

// Word wrap enabled (default)
new TextNode("Long text that will wrap at word boundaries")

// Word wrap disabled (truncate)
new TextNode("Text that won't wrap").NoWrap()

When to use NoWrap

Use .NoWrap() for:

• Status bar items
• Single-line displays
• Content that should truncate rather than overflow

Styled Labels Pattern

For consistent styled text throughout your app:

// In a helper class
public static class Styles
{
    public static TextNode Header(string text) =>
        new TextNode(text)
            .Bold()
            .WithForeground(Color.BrightCyan);

    public static TextNode Error(string text) =>
        new TextNode(text)
            .WithForeground(Color.Red);

    public static TextNode Success(string text) =>
        new TextNode(text)
            .WithForeground(Color.Green);

    public static TextNode Muted(string text) =>
        new TextNode(text)
            .WithForeground(Color.Gray);
}

// Usage
Layouts.Vertical()
    .WithChild(Styles.Header("Welcome"))
    .WithChild(Styles.Muted("Press any key..."))

Terminal Compatibility

WARNING

Not all terminals support all text styles:

Style	Compatibility
Bold	Wide support
Italic	Most modern terminals
Underline	Wide support

Some terminals render bold as bright colors instead of heavier font weight.

Properties Reference

Property	Type	Default	Description
IsBold	bool	false	Bold text
IsItalic	bool	false	Italic text
IsUnderline	bool	false	Underlined text
WordWrap	bool	true	Enable word wrapping

StreamingTextNode Inline Styling

For streaming content with inline styles, use the styled append methods:

var stream = StreamingTextNode.Create();

// Inline colors and decorations
stream.Append("Error: ", foreground: Color.Red, decoration: TextDecoration.Bold);
stream.AppendLine("Something went wrong");

// Combine multiple decorations
stream.Append("Important",
    foreground: Color.Yellow,
    decoration: TextDecoration.Bold | TextDecoration.Underline);

See StreamingTextNode for full documentation on inline styled text.
