This directory contains input, a simple tool to inject input events into Scenic.
input [<options>] text|keyevent|tap|swipe <args> input text <text> input keyevent <hid_usage (int)> input tap <x> <y> input swipe <x0> <y0> <x1> <y1>
the duration of the event, in milliseconds (default: 0)
Text is injected by translating a string into keystrokes using a QWERTY keymap. This facility is intended for end-to-end and input testing purposes only.
Only printable ASCII characters are mapped. Tab, newline, and other control characters are not supported, and
keyevent should be used instead.
The events simulated consist of a series of keyboard reports, ending in a report with no keys. The number of reports is near the lower bound of reports needed to produce the requested string, minimizing pauses and shift-state transitions.
--duration is divided between the reports. Care should be taken not to provide so long a duration that key repeat kicks in.
Note: when using through
fx shell with quotes, you may need to surround the invocation in strong quotes, e.g.:
fx shell 'input text "Hello, world!"'
This facility will eventually use IME for general text input, removing the above limitations. Keystroke mapping will remain as a specialized utility. At that point, the Dvorak keymap will also be suppported.
This command simulates a single key down + up sequence. The argument is a decimal HID usage code, prior to any remapping the IME may do.
Common usage codes:
These commands simulate touch events.
By default, the x and y coordinates are in the range 0 to 1000 and will be proportionally transformed to the current display, but you can specify a virtual range for the input with the
