0.10.0 - 2026-07-27

Release Notes

Added

• Named themes. theme = "high-contrast" in place of the [theme] table.
  Four ship inside the binary — default, default-light, high-contrast and
  ansi — and anything in themes/<name>.toml beside your config is found
  first, so a bundled theme can be replaced without renaming it.

  A theme file may inherits another, so a variant is the lines that differ
  rather than a copy of all eighteen keys, and may define a [palette] of named
  colours. Redefining a palette entry in a child recolours the keys its parent
  set with it.

  The same key does both jobs and TOML decides which: a quoted string is a name,
  a table is colours written out. Your existing [theme] table keeps working
  and keeps its error messages — the misspelled-key report and the
  --migrate-config hint for the pre-0.1.0 rx/tx keys both survive, which
  an untagged enum would have flattened into "data did not match any variant".

  Not built, deliberately: dotted-scope fallback (sized for Helix's hundreds of
  syntax scopes, where mirador has thirteen flat semantic keys) and per-key
  style objects with fg/bg/modifiers (every theme read takes a flat colour, and
  emphasis belongs to the widget that knows what it is emphasising).

• A theme file with its colour keys after [palette] is refused by name.
  TOML puts every key following a table header inside that table, so those
  keys set nothing — without failing, without a typo, and with the theme quietly
  coming out as the defaults. mirador's own default.toml was written that way
  during development and the test comparing it against the built-in default
  passed, because a file that sets nothing resolves to exactly the default.
