Culture and Value Formatting

XenoAtom.Terminal.UI formats values using a configurable CultureInfo.

This affects common UI scenarios such as:

data templating (DataPresenter<T>, list item templates, etc.)
default formatting of numeric values in controls (for example Slider<T>)

By default, the culture is CultureInfo.InvariantCulture (stable formatting across machines and locales).

Setting the application culture

Fullscreen (`Terminal.Run`)

using System.Globalization;
using XenoAtom.Terminal.UI;

Terminal.Run(
    visual,
    onUpdate,
    new TerminalRunOptions
    {
        Culture = CultureInfo.GetCultureInfo("fr-FR"),
    });

Inline (`Terminal.Live`)

using System.Globalization;
using XenoAtom.Terminal.UI;

Terminal.Live(
    visual,
    onUpdate,
    new TerminalLiveOptions
    {
        Culture = CultureInfo.GetCultureInfo("fr-FR"),
    });

Overriding culture for a subtree

You can override formatting for a specific subtree by setting CultureStyle in the environment:

using System.Globalization;
using XenoAtom.Terminal.UI.Styling;

root.Style(CultureStyle.Default with
{
    Culture = CultureInfo.GetCultureInfo("fr-FR"),
});

This is useful when you want most of the UI to use one culture, but a specific panel to use another.

Formatting helpers

Controls and templates should prefer using Visual helpers rather than calling ToString() directly:

Visual.ToStringValue<T>(T value, string? format = null)
Visual.ToStringObject(object? value, string? format = null)

These helpers automatically pick up the resolved culture.
