Themes

Press t for an fzf-style picker to switch themes live, or set one in config. Built-in presets: default, monokai, solarized, catppuccin, synthwave84.

Configure under a [theme] table in your mantis.toml. name selects a preset as the base; each role then overrides it. A role takes a color name (cyan, lightyellow, reset) or a hex value (#aabbcc); syntax is a syntect theme name for file contents. Anything left unset keeps the preset’s value.

Presets ship their own background color; the default theme leaves it transparent (the terminal’s background). Set transparent_background = true to keep a preset’s colors but use your terminal’s background instead.

The background role controls panel backgrounds. When set to reset (the default), the terminal’s own background shows through. Each preset ships a preferred background color that you can override or disable with transparent_background. On top of presets, live theme switching instantly re-applies the current file with the new syntax highlighting theme.
