About

UnnaturalCode is a system with the purpose of augmenting the compiler's own syntax error location strategies. It is designed to assist the developer in locating syntax errors in their software. For more information, please consult the UnnaturalCode paper (preprint).

UnnaturalCode should be considered proof-of-concept quality software. The primary author of UnnaturalCode, Joshua Charles Campbell can be reached at joshua2@ualberta.ca.

Install

Clone this repository with the recursive option:

git clone --recursive https://github.com/orezpraw/unnaturalcode.git

Alternatively, clone this repository, then initialize git-submodules.

git submodule update --init

This will also clone MITLM.

macOS: MITLM requires gfortran, which must be installed before running pip install.

brew install gcc

Then, prior to the pip install, set the LIBRARY_PATH as appropriate:

export LIBRARY_PATH="$(dirname $(brew list gcc | grep libgfortran.a | tail -1)):$LIBRARY_PATH"

Create a virtualenv (optional), then:

pip install -e .

Must set the PATH for the following compilers:

JavaScript:

  • Babel
  • V8
  • EsLint
  • JavaScriptCore

Execute the following for each compiler:

export PATH=/YOUR_LOCATION_OF_FILE/:$PATH

An example for Babel:

export PATH=/home/dhvani/node_modules/.bin:$PATH

Requirement for Java:

Path to ecj-4.7.jar (Eclipse compiler standalone jar) must be set in check_eclipse_syntax.py

Use

To start the HTTP server:

python -m unnaturalcode.http
