egui_font_loader

A simple library to simplify egui font loading

How to load fonts

Important! It's advised to load the font only once and avoid doing it in the update function.

Fonts need to be found locally.

Single font

To load a single font known at compile time, it's suggested to use the load_font macro

load_font!(ctx, "DesiredFontName", "path/to/font.ttf");

The DesiredFontName can be anything, just keep it in mind to load it later on.

Multiple fonts at once

use egui_font_loader::LoaderFontData;
use egui_font_loader::load_fonts;
let fonts = vec![
    LoaderFontData {
        name: "DesiredFontName".into(),
        path: "path/to/custom/font/first.ttf".into(),
    },
    LoaderFontData {
        name: "SecondCustomFont".into(),
        path: "path/to/custom/font/second.ttf".into(),
    },
];
load_fonts(&egui_ctx, fonts).unwrap();

How to use the loaded font

// Some code
ui.heading(
    RichText::new("Code By RakuJa")
        .color(Color32::from_rgb(102, 0, 51))
        .font(FontId {
            size: 15.0,
            family: FontFamily::Name("DesiredFontName".into()),
        }),
);
// Some other code

How to load only once the desired fonts

In the main.rs

eframe::run_native(
    "My window title",
    options,
    Box::new(|cc| {
        Ok(Box::new(MyApp::new(cc)))
    }),
)

In myapp.rs

impl MyApp {
    pub fn new(
        cc: &eframe::CreationContext<'_>,
    ) -> Self {
        // This is also where you can customize the look and feel of egui using
        // `cc.egui_ctx.set_visuals` and `cc.egui_ctx.set_fonts`.
        load_fonts(&cc.egui_ctx, vec![/*add LoaderFontData here*/]).unwrap();
        Self {//initialize it}
    }
}
