## Introduction

Grayskull is an automatic conda recipe generator.

The main goal of this project is to generate concise recipes
for [conda-forge](https://conda-forge.org/).
The Grayskull project was created with the intention to eventually replace `conda skeleton`.

Presently Grayskull can generate recipes for Python packages available on PyPI and also those not published on PyPI but available as GitHub repositories.
Grayskull can also generate recipes for R packages published on CRAN.
Future versions of Grayskull will support recipe generation for packages of other repositories such as Conan and CPAN etc..

## Installation

It is possible to install this project using `pip`:
```bash
pip install grayskull
```

or `conda`, using the ``conda-forge`` channel:
```bash
conda install -c conda-forge grayskull
```

It is also possible to clone this repo and install it using `pip`:
```bash
git clone https://github.com/conda/grayskull.git
cd grayskull
pip install -e .
```

## Usage

It is pretty simple to use `grayskull`. Just call it, pass the repository
(`pypi` or `cran`) and the package name.

* Example:
```bash
grayskull pypi pytest
```

After that `grayskull` will create a folder with the same name as the package
and inside this folder the generated recipe will be present (`meta.yaml`).

* Example with `pytest` (`grayskull pypi pytest`):

![Grayskull CLI](https://github.com/conda/grayskull/raw/main/images/cli_example_grayskull.gif)

If your package is a GitHub repository just replace the package name with the GitHub repository URL.

For example:

```bash
grayskull pypi https://github.com/confluentinc/confluent-kafka-python
```

You can also generate a recipe from a local sdist archive:

```bash
grayskull pypi ./pytest-5.3.5.tar.gz
```

Note that such a recipe isn't really portable as it will depend on the local path of the
sdist file. It can be useful if you want to automatically generate a conda package.

### Online Grayskull

It is also possible to use Grayskull without any installation. You can go to this website [marcelotrevisani.com/grayskull](https://www.marcelotrevisani.com/grayskull) and inform the name and the version (optional) of the package and it will create the recipe for you.
