Sensibility

Finds and fixes syntax errors. This is experimental software.

NOTE: Please use the saner2018 tag if you're looking to replicate the results from our SANER 2018 paper. Find the replication data on archive.org See Citation for how to cite this paper. Use the following to clone Sensibility with the correct branch:

git clone --branch=saner2018 https://github.com/naturalness/sensibility.git

Requirements

Sensibility requires:

• Python 3.6.

For fixing Java files:

• Java 8 SE

For fixing JavaScript files:

• Node.JS >= 6.0 and ZeroMQ (macOS: brew install zeromq; Ubuntu: apt install libzmq-dev)

Researchers that wish to mine more repositories or languages will require:

• A running Redis server.

Researchers wishing to evaluate the current methods will require:

• UnnaturalCode

Install

Activate a virtualenv, if that's your thing. Then,

pip install -e .

Usage

Once installed, there's one entry point to all the scripts and utilities included:

sensibility <SUBCOMMAND>

Most subcommands require the specification of a language, with the -l <LANGUAGE> option before the subcommand.

For example, to train Java models:

sensibility -l java train-list --help

Development

The following diagram visualizes the data flow. Subcommands to sensibility are in black rectangles; white ovals are products. Please contact the author to obtain the mistake database, which is only applicable when evaluating the Java models.

Tests

To run the tests, install tox using Pip, then run tox.

Mining repositories

1. You must create a GitHub OAuth token and save it as .token in the repository root.

2. Run redis-server on localhost on the default port.

3. Use sensibility mine find-repos to get a list of the top ~10k repos:

   sensibility mine find-repos javascript | sort -u > javascript-repos.txt
   

4. Use bin/enqueue-repo to enqueue repos to download:

   sensibility mine enqueue-repo < javascript-repos.txt
   

5. Start one or more downloaders. These will dequeue a repo from the running Redis server and download sources:

   sensibility mine download
   

Evaluation

Type make experiments to train all of the models and evaluate each one. See libexec/experiments for more details.
