Data Preprocess

Processing data into forms that each NPR system needs Preprocess_RawData.py

Before data preprocessing, you need to prepare your data into a filedir including:

|---data_dir
   |---data.ids: each line has a id to identify data samples
   |---buggy_lines: each file contains the buggy line of a sample
   |---buggy_methods: each file contains the buggy method of a sample
   |---buggy_classes: each file contains the buggy class of a sample
   |---fix_lines: each file contains the developer patch line of a sample
   |---fix_methods: each file contains the developer patch method of a sample
   |---fix_classes: each file contains the developer patch class of a sample
   |---metas: meta information of data samples

Training

To train a NPR system, you can use a simple command like this:

python train.py -model NPR_SYSTEM_NAME -config CONFIG_FILE_PATH

Generating Patches

To use a trained NPR system to generate patches, you can use a simple command like this:

python translate.py -model NPR_SYSTEM_NAME -config CONFIG_FILE_PATH
