# SWE-PolyBench

[SWE-PolyBench](https://github.com/amazon-science/SWE-PolyBench) is a multi language repo level software engineering benchmark. Currently it includes 4 languages: Python, Java, Javascript, and Typescript. The number of instances in each language is:

Javascript: 1017

Typescript: 729

Python: 199

Java: 165

## Datasets

There are total *two* datasets available under SWE-PolyBench. `AmazonScience/SWE-PolyBench` is the full dataset and `AmazonScience/SWE-PolyBench_500` is the stratified sampled dataset with 500 instances.

## Leaderboard

We evaluated several open source coding agents/models on this dataset and report them in our [leaderboard]().

## Submit

To submit your predictions on this dataset, please follow this [README](https://github.com/amazon-science/SWE-PolyBench/blob/submission/README.md)

## Languages

The text of the dataset is primarily English.

## Dataset Structure

An example row from the dataset includes the following columns:
```
instance_id: (str) - A formatted instance identifier, usually as repo_owner__repo_name-PR-number.
patch: (str) - The gold patch, the patch generated by the PR (minus test-related code), that resolved the issue.
repo: (str) - The repository owner/name identifier from GitHub.
base_commit: (str) - The commit hash of the repository representing the HEAD of the repository before the solution PR is applied.
hints_text: (str) - Comments made on the issue prior to the creation of the solution PR’s first commit creation date.
created_at: (str) - The creation date of the pull request.
test_patch: (str) - A test-file patch that was contributed by the solution PR.
problem_statement: (str) - The issue title and body.
F2P: (str) - A json list of strings that represent the set of tests resolved by the PR and tied to the issue resolution.
P2P: (str) - A json list of strings that represent tests that should pass before and after the PR application.
language: (str) - The programming language
Dockerfile: (str) - The instance level dockerfile
test_command: (str) - The test command used to get F2P and P2P
task_category: (str) - The problem classification (Bug Fix, Refactoring, Feature)
is_no_nodes: (bool) - Helpful info for evaluating retrieval metrics
is_func_only: (bool) - Helpful info for evaluating retrieval metrics
is_class_only: (bool) - Helpful info for evaluating retrieval metrics
is_mixed: (bool) - Helpful info for evaluating retrieval metrics
num_func_changes: (int) - Helpful info for evaluating retrieval metrics
num_class_changes: (int) - Helpful info for evaluating retrieval metrics
num_nodes: (int) - Helpful info for evaluating retrieval metrics
is_single_func: (bool) - Helpful info for evaluating retrieval metrics
is_single_class: (bool) - Helpful info for evaluating retrieval metrics
modified_nodes: (bool) - Helpful info for evaluating retrieval metrics
```
