This directory contains helper scripts written in bash and python for code clone analysis.

• The python script generate_clone_pairs.py aggregates the clone pair data in the FortranAS.sqlite3 database.
• The bash script explore_clones.py automates diffing of the clone pairs with any diff tool such as meld..

Before running these tools a FortranAS.sqlite3 database is required. Run FortranAS -c or --calculate-code-clones flag before running these tools.

There is a python script provided in this directory called generate_clone_pairs.py that reads the FortranAS.sqlite3 database and generates clone pair files in the output directory (output/clones). This script also generates a clone database called clones.sqlite3 in the same output directory (output/clones/clones.sqlite3).

To run clone pair generation first run FortranAS on your FORTRAN source code to generate a FortranAS.sqlite3 database. Once you have a database you can run this script with:

python3 generate_clone_pairs.py

The output clone pair directory containing a reference and candidate can be diffed using and diff tool such as meld.

Open the directories output/clones/references and output/clones/candidates using a directory comparison using a diff tool.

Alternately, you can use the provided shell script to do an automated iterated diff over all clone pairs in output/clones using the provided shell script (explore_clones.sh). In the following example meld is used

1. Set the DIFFTOOL environmental variable:

export DIFFTOOL=meld

2. Run the explore_clones.sh shell script:

bash explore_clones.sh
