xrecord-echo echo XRecord events by nanomsg library. Any can subsribe to it.

Event message contains info about window and process where it triggered. Message looks like that:

{
  "event_type": "KeyEvent",
  "xserver_time": 12255472,
  "timestamp": 1441459157,
  "wm_name": "alxkolm/rust-xrecord-echo - Google Chrome",
  "wm_class": "Google-chrome-stable",
  "pid": 5077,
  "proc_name": "chrome",
  "proc_cmd": "/opt/google/chrome/chrome",
  "code": 11
}

Install

Prerequisites

• Rust compiler
• nanomsg (tested on >=0.5)

To install all of prerequisites and build xrecord-echo run:

make

# Install for systemd based linux distributions (ex. Ubuntu)
make install

To just build xrecord-echo use cargo:

cargo build --release

Run

To run xrecord-echo use start script. It automaticaly respawn process when it crush.

But I recommend use supervisor like runit to manage process (run on system startup and restart on crash).

xrecord-echo emit messages as publisher on port 1234.

To check that this work use nanomsg tools to subscribe and output to terminal:

nanocat --sub -l1234 -A

Setup systemd

cp xrecord-echo.service ~/.config/systemd/user
systemctl --user enable xrecord-echo.service
systemctl --user start xrecord-echo.service

Todo

• Customize nanomsg port by command line parameters
• Implement XRecord error callback
