e-Knife: Erlang slicing with the Expression Dependence Graph

You can find more details and contact information at the project's homepage.

This project consists of three modules:

• e-Knife: the frontend for the EDG, which implements the necessary tools to slice Erlang programs.
• EDG: the generic library that implements the graph and slicing techniques.
• Miscellaneous: various shared utilities.

Build

Requirements: Java >= 8, Erlang/OTP 24 and Apache Ant.

Just run ant and a jar will be built at ./dist/.

Build with another version of Erlang

Before running ant, replace the package com.ericsson.otp.erlang from e-Knife/src with the one from your Erlang distribution, at lib/jinterface-VERSION/java_src.

Your Erlang distribution will most likely be installed at /usr/lib/erlang or /usr/local/lib/erlang.

As an example:

pkg="com/ericsson/otp/erlang"
rm -rf e-Knife/src/$pkg
mv /usr/lib/erlang/lib/jinterface-1.12/java_src/$pkg e-Knife/src/$pkg

Run

You'll probably want to generate slices, so you should run e-Knife. Run it without args to obtain a list and explanation of arguments.

java -jar path/to/eknife.jar [args]

Importing into an IDE

You can treat each folder (EDG, e-Knife and Miscellanea) as a separate module, with the following dependencies:

• e-Knife requires EDG and Miscellanea.
• EDG requires Miscellanea.
• Miscellanea has no dependencies.
