Module Miaou_style.ThemeSource

Theme definition with semantic styles and CSS-like widget styling rules.

A theme consists of:

  • Semantic styles (primary, error, text, etc.) for consistent appearance
  • Widget rules using CSS-like selectors for targeted styling

Example theme JSON:

{
  "name": "dark",
  "primary": { "fg": 75, "bold": true },
  "error": { "fg": 196 },
  "text": { "fg": 252 },
  "border": { "fg": 240 },
  "rules": {
    "table:focus": { "style": { "border_fg": 75 } },
    "flex_layout > :nth-child(even)": { "style": { "bg": 236 } },
    "modal .button": { "style": { "fg": 255, "bold": true } }
  }
}

  1. style : Style.t;
    (*
