import-theme translates a HyDE hypr.theme into cosmic.conf, reusing the
Phase 1 parser — which is the payoff for choosing Hyprland-style syntax.
Nothing is dropped silently. Every source key either lands in the output or
carries a Note explaining why not, classified as NoEquivalent,
NeedsCompositorPatch, DifferentProgram or Lossy. Gradient borders contribute
their first stop as the accent and say so.
Handles real-world quirks found in actual theme files: HyDE's |> destination
header (no '=', would otherwise be a parse error), colon-keys like
shadow:enabled, and nested blur blocks.
Tests run against the verbatim Catppuccin-Mocha theme, and assert that the
generated conf both parses and resolves against the registry. Verified
end-to-end on Tokyo-Night, a theme absent from the tests: import -> apply
produced 8 correct cosmic-config files with 20 settings reported.
64 tests.
emit writes RON directly rather than linking libcosmic. Spike 2 showed
cosmic-config is a filesystem KV store whose notify watcher keys off file
paths (lib.rs:377), so an atomic write is observed identically to the typed
API — for the cost of ron instead of the whole libcosmic graph.
Two-stage: plan renders without touching disk, apply writes. Composites are
read-modify-write against verified upstream defaults — gaps (0,8) at
theme.rs:939, CornerRadii at corner.rs:20-31 — so setting one field never
drops its siblings. Unmodelled composites error rather than write blind.
52 tests. CLI verified end-to-end: apply, --diff (writes nothing), idempotent
rerun, partial update preserving siblings, and multi-diagnostic failure with
exit 1 and zero writes.
Spike results corrected the spec: ThemeBuilder.gaps is (outer, inner) at
cosmic-theme/src/model/theme.rs:895, lives under CosmicTheme.{Dark,Light}.Builder
rather than CosmicTk, and fans out to two components. Entry therefore carries
targets: &[Target].
34 tests, including the folding property that keeps gaps_out from clobbering
gaps_in. Bare #rrggbb colours rejected: # begins a comment, as in Hyprland.
HyDE-style desktop on cosmic-comp: single-file Hyprland-idiom config
compiler, wlr-foreign-toplevel + Hyprland-compatible IPC patches, waybar
