"""Probe the kitty keyboard protocol by printing the raw bytes each key sends.
|
|
|
|
Run it inside a terminal to see what that terminal emits under a chosen set of
|
|
progressive-enhancement flags:
|
|
|
|
python3 scripts/kitty-probe.py [flags]
|
|
|
|
`flags` is the decimal flag set to enable (default 1):
|
|
|
|
1 disambiguate escape codes
|
|
2 report event types (press/repeat/release)
|
|
4 report alternate keys
|
|
8 report all keys as escape codes
|
|
16 report associated text
|
|
|
|
Combine by adding, e.g. 15 for everything but text, 31 for everything. Press
|
|
Esc to quit; the previous keyboard mode is restored on exit.
