Launch the real Waybar binary inside a headless, software-rendered sway compositor and verify it actually runs and renders — something the unit tests and build jobs never do. - test/smoke/run.sh: boots sway (WLR_BACKENDS=headless, pixman), starts waybar, asserts it stays alive with no fatal log, optionally grabs a screenshot with grim - level 1: real modules (clock/cpu/memory/disk) load without crashing - level 2: deterministic config is screenshotted and checked to be non-blank - level 3: screenshot compared to test/smoke/reference.png (fuzz 8%, 800px tolerance); screenshot + diff uploaded as artifacts - .github/workflows/smoke.yml runs it on push/PR The reference image must be blessed from a CI artifact (see test/smoke/README.md).

# Launch Waybar inside a headless sway compositor and verify it starts and
|
|
# renders. Used by the `smoke` CI workflow.
|
|
#
|
|
# Usage: run.sh <config> [style] [screenshot.png]
|
|
# - always: assert waybar launches, stays alive, logs no fatal error
|
|
# - if <screenshot.png> given: capture the bar with grim
|
|
#
|
|
# Requires: sway, grim, waybar (on PATH). Software-rendered, no GPU needed.
