key-recorder is a very simple keyboard-input-recorder. It will silently record user kb input events. It could record for 81 keys that are used often.
When recieving a SIGINT (or CTRLC) signal, it will store the recorded events from starting till ending in a txt file under ./records/.
The format for the txt files is "record-{starttime}-{endtime}"。
The 1st line of the txt file is starttime, 2nd is endtime, 3rd is 81 integers, representing the number of keyboard down for every key, 4th is a serial of kb events during this time.
About in actual which key does a integer in 3rd line represent for, you could find in the 347 line in main.rs.
This project depends on device_query-1.0.0, chrono-0.4.19, ctrlc-3.2.1. Since divice_query is a cross-platform crate, this project will also be cross-platform.
This is not a globally keyboard detector.
When some other Apps (especially full-screen App) running, key-recorder will not work. I have tested several games and Apps on Win10 including Genshin Impact, NARAKA.
I presently thought the reason is that under windows these Apps monopolize kb, of they hung-up key-recorder forcely.
This problem may be solved by Hook in Winapi. I plan to implement this by Rust, but C++ of .NET will be probably easier.
I haven't investigate how to solve this problem under Linux, but it will be likely easier.
If you are in interest, you could do whatever you want to the txt file.
You could also make other programs, running this program backgroundly.
Because I have intended to make a globally keyboard detector, I haven't do these jobs on this project.
