winidle

winidle prints the idle time on Windows(R) and Linux systems in milliseconds.

Build

Requires cmake and a C compiler.

Linux (CMake)

Uses the Xscreensaver library to get the idle time.

mkdir build
cd build
cmake ..
make

Will create the executable src/winidle.

Linux (manually)

gcc -o winidle src/winidle.c -lX11 -lXss

Windows (cross-compilation)

mkdir build-w32
cd build-w32
cmake .. -DCMAKE_TOOLCHAIN_FILE=../Toolchain-mingw32.cmake
make

Will create the executable src/winidle.exe.

Windows (native)

Use CMake to generate a Visual Studio project, open and build it. This part is currently untested.

How to use it in org-mode

(defun org-user-idle-seconds ()
  "Return the current Win idle time in seconds."
  (/ (string-to-number (shell-command-to-string "winidle.exe")) 1000))
