Pre-training data

See tracer/README.md.

⚠️ WIP: We are making the tracer tool available to foster further research. Please be aware that the currently-released version of the tracer tool may not reproduce our work, as we have not fully verified it end-to-end. Thank you!

Important Note For Data Pre-processing: TRACED needs to align the execution states, such as dynamic values of identifiers, with syntactically valid code tokens, which requires the data pre-processing. To avoid the distribution shift, the task-specific fine-tuning data needs to do the same pre-processing with AST parser:

• Parse the source code with Tree-sitter and tokenize the sequence following the grammar of corresponding programming languages.

Check out our data samples for the expected format of the pre-processed code.
