Long Command Runner

pipeline status Gem Version coverage report

This lib aims to follow a terminal command that is long to execute and monitor the CPU usage and the progression of the program.

Current state and goal

Currently (what we have)

  • monitoring of the progression of the application through the output of the app (I don't think that we can do better)
  • get the real/user/sys time usage of the application by using the lib Benchmark of ruby.

v1 goal

  • Make it pure ruby solution not depending on bash
  • Realtime mesure of cputime usage

gem install long-command-runner

  STDOUT.write "\rProgram is at: #{runner.progress} %   \r"
  STDOUT.flush
