MultiLang-Code-Parser-Dataset
MultiLang Code Parser Dataset (MLCPD)
MultiLang-Code-Parser-Dataset (MLCPD) provides a large-scale, unified dataset of parsed source code across 10 major programming languages, represented under a universal schema that captures syntax, semantics, and structure in a consistent format.
Each entry corresponds to one parsed source file and includes:
Language metadata
Code-level statistics (lines, errors, AST nodes)
Universal Schema JSON (normalized structural representation)

💻 StackOverflow-778K: Multi-Year Developer Q&A Dataset
Dataset Summary
A large-scale Stack Overflow question dataset containing 778,929 unique
questions sampled across 7 years (2015–2022). Each question includes the
raw HTML body, plain-text version, tags, score, view count, answer count, and
a rich set of derived features for immediate ML use.
Collected across 8 sampling runs on Feb 27 2026, deduplicated to
778,929 unique questions with only 2 duplicates removed.… See the full description on the dataset page: https://huggingface.co/datasets/Omarrran/StackPulse_778K_QnA_Code_dataset.crowd-code-dataset-0.1The crowd-code-dataset-0.1 is a raw, unfiltered dataset of fine-grained IDE interactions collected during the development of Jasmine using crowd-code, a VS Code/Cursor extension capturing large parts of the software engineering workflow.
The dataset captures real research engineering workflows (character-level edits, navigation, terminal use, iterative debugging). The crowd-code-dataset-0.1 only includes data from the Jasmine authors. We are actively working on cleaning and curating the full… See the full description on the dataset page: https://huggingface.co/datasets/p-doom/crowd-code-dataset-0.1.team1_dataset_play_diatonic_codeThis dataset was created using LeRobot.

pde-llm-eval-code-perturbation-dataset
Code Perturbation Dataset (final). 256 PDE solver implementations: 64 base programs (32 physically valid, 32 with an injected bug that still runs to completion) expanded by 4 lexical perturbation conditions each -- original comments, comments removed, comments swapped in from a different implementation, and descriptive identifiers replaced by meaningless placeholders. The perturbations change the lexical surface only; executable behaviour… See the full description on the dataset page: https://huggingface.co/datasets/bermaneh/pde-llm-eval-code-perturbation-dataset.Dr-Zeon-Github-Python-Code-Dataset
Luck Spark 1B - High Quality Code Dataset
The first quality-scored, star-agnostic code dataset for training 1B MoE code models.
Unlike The Stack / CodeParrot that filter by stars, this dataset scores every file by its content (0-10). A 2-star well-documented library scores higher than a 10k-star minified file. Continuously updated by an autonomous bot.

🔐 Code Vulnerability Dataset (CWE-Enriched)
📌 Overview
This dataset is built from the bstee615/diversevul dataset and enhanced with structured vulnerability intelligence from the MITRE Common Weakness Enumeration (CWE) database.
It provides a rich, machine-readable representation of software vulnerabilities, mapping raw vulnerable code samples to standardized CWE classifications.
The dataset is designed for research and development in:
