This repository gathers all the code used to build the BigCode datasets such as The Stack as well as the preprocessing necessary used for model training.

• language_selection: notebooks and file with language to file extensions mapping used to build the Stack v1.1.
• pii: code for running PII detection and anonymization on code datasets.
• preprocessing: code for filtering code datasets based on:
  • line length and percentage of alphanumeric characters.
  • number of stars.
  • comments to code ratio.
  • tokenizer fertility
• decontamination: script to remove files that match test-samples from code generation benchmarks.
