swipe-sim

Overview ¶

swipe-sim drives the /api/debug/swipe endpoint in a loop so you can watch transition smoothness in real time and tune parameters quickly.

Usage:

go run ./cmd/swipe-sim [flags]

Flags:

-addr        Backend base URL (default http://localhost:1985)
-dir         Swipe direction: left|right|alternate (default alternate)
-duration    Drag phase duration in ms (default 200)
-finalize    Snap animation duration in ms (default 120)
-steps       Drag steps — higher = smoother simulation (default 20)
-velocity    Release velocity in px/s; real swipes ~120–500 (default 150)
-count       Number of swipes to run, 0 = loop forever (default 0)
-gap         Pause between swipes in ms (default 800)
-analyse     Connect to WS, capture frames, and print per-frame displacement
             and smoothness analysis after each swipe

Examples:

# Rapid alternating swipes — watch in Flutter UI
go run ./cmd/swipe-sim

# Analyse one swipe: see frame-by-frame displacement and smoothness report
go run ./cmd/swipe-sim -dir left -count 1 -analyse

# Simulate a fast flick (400 px/s) with analysis
go run ./cmd/swipe-sim -dir left -count 1 -velocity 400 -analyse

# Tune: slow drag (400ms), many steps, with analysis
go run ./cmd/swipe-sim -duration 400 -steps 40 -count 2 -analyse
