# IVA Swift GitHub Code Dataset

## Dataset Description

This is the curated IVA Swift dataset extracted from GitHub. 
It contains curated Swift files gathered with the purpose to train a code generation model.

The dataset consists of 383380 swift code files from GitHub totaling ~542MB of data. 
The [uncurated](https://huggingface.co/datasets/mvasiliniuc/iva-swift-codeint) dataset was created from the public GitHub dataset on Google BiqQuery.

### How to use it

To download the full dataset:

```python
from datasets import load_dataset
dataset = load_dataset('mvasiliniuc/iva-swift-codeint-clean', split='train')
```

```python

from datasets import load_dataset
dataset = load_dataset('mvasiliniuc/iva-swift-codeint-clean', split='train')
print(dataset[723])

## Data Structure

### Data Fields

|Field|Type|Description|
|---|---|---|
|repo_name|string|name of the GitHub repository|
|path|string|path of the file in GitHub repository|
|copies|string|number of occurrences in dataset|
|content|string|content of source file|
|size|string|size of the source file in bytes|
|license|string|license of GitHub repository|
|hash|string|Hash of content field.|
|line_mean|number|Mean line length of the content.
|line_max|number|Max line length of the content.
|alpha_frac|number|Fraction between mean and max line length of content.
|ratio|number|Character/token ratio of the file with tokenizer.
|autogenerated|boolean|True if the content is autogenerated by looking for keywords in the first few lines of the file.
|config_or_test|boolean|True if the content is a configuration file or a unit test.
|has_no_keywords|boolean|True if a file has none of the keywords for Swift Programming Language.
|has_few_assignments|boolean|True if file uses symbol '=' less than `minimum` times.

## Dataset Statistics

```json
{
    "Total size": "~542 MB",

## Curation Process

* Removal of duplication files based on file hash.
* Removal of file templates. File containing the following: `___FILENAME___, ___PACKAGENAME___, ___FILEBASENAME___, ___FILEHEADER___, ___VARIABLE`
* Removal of the files containing the following words in the first 10 lines: `generated, auto-generated", "autogenerated", "automatically generated`
* Removal of the files containing the following words in the first 10 lines with a probability of 0.7: `test", "unit test", "config", "XCTest", "JUnit`
* Removal of file with the rate of alphanumeric characters below 0.3 of the file.
* Removal of near duplication based MinHash and Jaccard similarity.
* Removal of files with mean line length above 100.
* Removal of files without mention of keywords with a probability of 0.7: `struct ", "class ", "for ", "while ", "enum ", "func ", "typealias ", "var ", "let ", "protocol ", "public ", "private ", "internal ", "import "`
* Removal of files that use the assignment operator `=` less than 3 times.
* Removal of files with the ratio between the number of characters and number of tokens after tokenization lower than 1.5.

Curation process is a derivation of the one used in CodeParrot project: https://huggingface.co/codeparrot

## Data Splits
The dataset only contains a train split which is separated into train and valid which can be found here:
