## Install (tested on Ubuntu 16.04 and OSX 10.12.6)

pip install phriky_units

Requires Cppcheck greater than 1.75:

apt-get install cppcheck (Ubuntu 16.04)

brew install cppcheck (OSX)

git clone git:// (Ubuntu 14.04)


You can run examples by checking out:

git clone

Then from that directory run:

phriky_units ./examples/addition/src/action.cpp

phriky_units ./examples/assignment/src/trajectory_planner_ros.cpp

phriky_units ./examples/comparison/src/twist_marker.cpp


  • Detects physical unit inconsistencies, like adding quantities with different units, i.e. meters + seconds.
  • Lightweight static analysis
  • Path insensitive
  • No annotation burden
  • Low false positive rate (&lt; 15% for `high-confidence’ inconsistencies)
  • Works with [ROS]
