kevinveenbirkenbachandClaude Opus 5.5 024259e89d feat(design): recolour single-colour logos per slot and preview every app's assets
A logo whose solid pixels share one colour (alpha >= 128, every channel within 24) is detected once per file and tinted to the text colour of each slot: frame_fill on frame slots, fill elsewhere, plus a prefers-color-scheme: dark variant in the SVG of page slots and the page text colour for the favicon. Edge pixels below half opacity are ignored so antialiasing does not count as a second colour. Multi-colour logos render byte-identical to before.

make design-logos (alias i8delo) renders every role with a design entry from one logo and base colour into an HTML page with day and night tiles, without a deploy. Slots render in four threads and roles in one process per CPU: the full preview went from 287.6s to 33.2s with identical output (diff -rq over 1229 PNGs). A GPU does not pay off for these PIL resizes.

Shared Utilities (utils/)

This directory contains shared Python helpers used by custom modules and plugins.

Purpose

Use utils/ for reusable code that should not be duplicated across:

  • library/ modules,
  • plugins/action/,
  • plugins/filter/,
  • plugins/lookup/.

Typical shared utilities:

  • API clients,
  • validation/conversion helpers,
  • path and configuration helpers,
  • cross-plugin/module domain logic.
  • Shared HTTP(S) connection handler for multiple modules.
  • Common validation or transformation functions for user input.
  • Utility functions for interacting with Docker, LDAP, etc.
  • Grouped helper packages such as utils/domains/ for related domain logic.

Design Guidelines

  • Keep helpers focused and composable.
  • Avoid side effects during import.
  • Prefer explicit function/class APIs over implicit globals.
  • Keep dependencies minimal so modules/plugins stay lightweight.

Example Import

from utils.domains.primary_domain import get_primary_domain

What Does Not Belong Here

  • Standalone executable modules (put in library/).
  • Ansible plugin entrypoints (put in plugins/*).
