Text Styles App in egui — RichText, Color32 & Formatting, Ep16

Learn how to style text in egui using RichText and Color32. We build a Text Styles app with toggleable sections showing headings, body text, color highlights, and warning styles — all with adjustable font size. Student code: https://github.com/GoCelesteAI/egui_text_styles What You'll Learn: • RichText::new() for creating styled text objects • .strong(), .italics(), .strikethrough(), .underline(), .monospace() formatting • .size() for dynamic font size control • Color32::from_rgb() for custom text colors (success green, error red, info blue) • ctx.set_pixels_per_point() to scale the entire UI • TopBottomPanel with a font size Slider • SidePanel with Checkboxes to toggle section visibility • CentralPanel with ScrollArea for scrollable content • Neo-tree keys to navigate between sources, buffers, and git views This is Episode 16 of the "Learn egui in Neovim" series where we build desktop apps with Rust's egui framework, all coded in Neovim.
