This release simplifies font handling, adds named colors and adds support for efficiently changing text dynamically.

Changes

Simplified Font Handling

In the past, you needed to pass around multiple Handle<Font>s for each variant of a font (e.g. bold, italic, bold and italic, etc.).

Instead, we now use a FontRegistry which automatically tracks which Fonts are loaded and allows to query them by font weight, style and other factors.
You can now simply specify an asset path where your fonts are stored and they will all be loaded and used inside of BBCode!

// Load the fonts inside of assets/fonts
BbcodePlugin::new().with_fonts("fonts")

Then inside of BbcodeSettings, you just specify the font family, size and color of the text to use by default:

BbcodeSettings::new("Fira Sans", 40., Color::WHITE)

Additionally, the new font tag allows you to change the font family for parts of the text:

[font="JetBrains Mono"]new font family[/font]

Named Colors

The color/c tag now also supports named colors, e.g. [c=primary]text[/c].
The color values are specified in the new ColorMap resource.

Changing a value in the color map resource will dynamically update all occurrences of this color in your app!

Dynamic Text Editing

Until this point, you could dynamically change the text in your app by changing Bbcode.content.
However, this adds a performance overhead as the entire markup needs to be parsed again and the UI hierarchy reconstructed.

Instead, you can now register marker components:

#[derive(Component, Clone)]
struct TimeMarker;

BbcodeSettings::new("Fira Sans", 40., Color::WHITE)
    // Register the marker component
    .with_marker("time", TimeMarker)

And then use it with the new m tag:

Time passed: [m=time]0.0[/m]

Finally, you can use queries to efficiently update the text:

fn update_text(time: Res<Time>, mut query: Query<&mut Text, With<TimeMarker>>) {
    for mut text in query.iter_mut() {
        text.sections[0].value = format!("{:.0}", time.elapsed_seconds());
}

Migration Guide

The BbcodePlugin now has a constructor and allows you to load an entire folder of fonts:

// Load the fonts inside of assets/fonts
BbcodePlugin::new().with_fonts("fonts")

In the BbcodeSettings you now specify the font family, size and color of the default text:

BbcodeSettings::new("Fira Sans", 40., Color::WHITE)

The initial release!
