shot_input.sh launches the app under Xvfb and drives it with xdotool, then screenshots for pixel-diff verification. Adds click/drag/rdrag pseudo-actions that insert the frame gap raylib's button edge-detection needs (a bare xdotool "click 1" is too fast and no-ops). Documents the settled-capture timing (12s) and the 1280x800 viewport/sidebar bounds. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

# Usage: shot_input.sh <output.png> [action ...]
|
|
# Launches rspektrum under Xvfb, runs input actions, captures the screen, cleans up.
|
|
#
|
|
# Actions (each runs in order):
|
|
# "sleep N" sleep N seconds locally (let the app settle / animate).
|
|
# Capture at "sleep 12" for a SETTLED render: the background
|
|
# high-res STFT fill runs over the first several seconds, so
|
|
# earlier grabs are nondeterministic run-to-run.
|
|
# "click X Y" left-click at (X,Y): move, press, hold ~0.2s, release.
|
|
# "drag X1 Y1 X2 Y2" left-drag from (X1,Y1) to (X2,Y2).
|
|
# "rdrag X1 Y1 X2 Y2" same but with Alt held (the app's pan gesture).
|
|
# "key NAME" xdotool keysym, e.g. "key F1", "key p", "key Home".
|
|
# anything else passed verbatim to xdotool (mousemove, mousedown, ...).
|
|
#
|
|
# IMPORTANT timing note: a left button's press and release MUST land in different
|
|
# 60 Hz frames or raylib's IsMouseButtonPressed edge-detect (current && !previous)
|
|
# never fires. The click/drag helpers below insert that gap; a bare "click 1" via
|
|
# xdotool is too fast and silently no-ops. Keys reach GLFW fine under Xvfb; so do
|
|
# synthetic mouse buttons (the pointer just has to be over a live target).
|
|
#
|
|
# Layout cheat-sheet at the default 1280x800 window (UI scale = 1.0):
|
|
# spectrogram viewport ~ x:[385,1242] y:[50,468] (drags/selections go here)
|
|
# sidebar ~ x:[0,320] (buttons; click centers)
|
|
# a selection box needs a >5 px drag or it reverts to "no selection".
