Overview

Package theme defines the editor's curated color palette. The editor intentionally ships one opinionated dark theme — there is no runtime configuration, no theme file, no JSON. To restyle the editor, edit this file and recompile. The palette is inspired by Tokyo Night and tuned so the syntax colors stay legible against the chrome.

	// FindMatch / FindCurrent paint search hits in the editor body.
	// FindMatch is a soft tint applied to every match in the viewport;
	// FindCurrent is the louder color drawn under the "active" match
	// (the one Enter/Esc-g will jump past) so the user can find their
	// place at a glance.
	FindMatch   tcell.Color
	FindCurrent tcell.Color

	// --- File tree ---
	FolderColor tcell.Color
	FileColor   tcell.Color

	// --- Syntax highlighting ---
	SynKeyword  tcell.Color
	SynString   tcell.Color
	SynNumber   tcell.Color
	SynComment  tcell.Color
	SynFunction tcell.Color

Theme bundles every color the editor renders. UI surfaces, accents, and syntax-highlight colors all live in one struct so that adjusting one element of the palette can be balanced against the others.

func Default

func Default() Theme

Default returns the editor's curated dark theme. It is the only theme the editor ships with — calling code can tweak fields on the returned value if it really needs to, but there is no theme-loading machinery on purpose.
