## About



This repo is a holding area for recipes destined for a conda-forge feedstock repo. To find out more about conda-forge, see https://github.com/conda-forge/conda-smithy.

## Feedstock conversion status



[![create_feedstocks](https://github.com/conda-forge/admin-requests/actions/workflows/create_feedstocks.yml/badge.svg)](https://github.com/conda-forge/admin-requests/actions/workflows/create_feedstocks.yml)



Failures with the above job are often caused by API rate limits from the various services used by conda-forge.

This can result in empty feedstock repositories and will resolve itself automatically.

If the issue persists, support can be found [on Gitter](https://gitter.im/conda-forge/conda-forge.github.io).



## Getting started



1. Fork this repository.

2. Make a new folder in `recipes` for your package. Look at the example recipe, our [documentation](http://conda-forge.org/docs/maintainer/adding_pkgs.html#) and the [FAQ](https://github.com/conda-forge/staged-recipes#faq)  for help.

3. Open a pull request. Building of your package will be tested on Windows, Mac and Linux.

4. When your pull request is merged a new repository, called a feedstock, will be created in the github conda-forge organization, and build/upload of your package will automatically be triggered. Once complete, the package is available on conda-forge.



## Grayskull - recipe generator for Python packages on `pypi`



For Python packages available on `pypi` it is possible to use [grayskull](https://github.com/conda-incubator/grayskull) to generate the recipe. The user should review the recipe generated, specially the license and dependencies.



Installing `grayskull`: `conda install -c conda-forge grayskull`



Generating recipe: `grayskull pypi PACKAGE_NAME_HERE`



## FAQ



### 1. **How do I start editing the recipe?**



Look at one of [these examples](https://github.com/conda-forge/staged-recipes/tree/main/recipes)

in this repository and modify it as necessary.



Follow the order of the sections in the example recipe. If you make a copy of example recipe, please remove the example's explainer comments from your recipe. Add your own comments to the recipe and build scripts to explain unusual build behavior or recipe options.



*If there are details you are not sure about please open a pull request. The conda-forge team will be happy to answer your questions.*



### 2. **How do I populate the `hash` field?**



If your package is on [PyPI](https://pypi.org), you can get the sha256 hash from your package's page on PyPI; look for the `SHA256` link next to the download link for your package.



You can also generate a hash from the command line on Linux (and Mac if you install the necessary tools below). If you go this route, the `sha256` hash is preferable to the `md5` hash.



To generate the `md5` hash: `md5 your_sdist.tar.gz`



To generate the `sha256` hash: `openssl sha256 your_sdist.tar.gz`



You may need the openssl package, available on conda-forge:

`conda install openssl -c conda-forge`



### 3. **How do I exclude a platform?**



Use the `skip` key in the `build` section along with a selector:



```yaml

build:

    skip: true  # [win]

```



A full description of selectors is [in the conda docs](https://docs.conda.io/projects/conda-build/en/latest/resources/define-metadata.html#preprocessing-selectors).



If the package can otherwise be `noarch` you can also skip it by using [virtual packages](https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-virtual.html). 



_Note_: As the package will always be built on linux, it needs to be at least available on there.



### 4. **What does the `build: 0` entry mean?**



The build number is used when the source code for the package has not changed but you need to make a new

build. For example, if one of the dependencies of the package was not properly specified the first time

you build a package, then when you fix the dependency and rebuild the package you should increase the build

number.



When the package version changes you should reset the build number to `0`.



### 5. **Do I have to import all of my unit tests into the recipe's `test` field?**



No, you do not. The main purpose of the test section is to test whether this conda package was built and installed correctly (not whether the upstream package contains bugs).



### 6. **Do all of my package's dependencies have to be in conda(-forge) already?**



Short answer: yes. Long answer: In principle, as long as your dependencies are in at least one of

your user's conda channels they will be able to install your package. In practice, that is difficult

to manage, and we strive to get all dependencies built in conda-forge.



### 7. **When or why do I need to use `{{ PYTHON }} -m pip install . -vv`?**



This should be the default install line for most Python packages. This is preferable to `python setup.py` because it handles metadata in a `conda`-friendlier way.



### 8. **Do I need `bld.bat` and/or `build.sh`?**



In many cases, no. Python packages almost never need it. If the build can be done with one line you can put it in the `script` line of the `build` section.



### 9. What does being a conda-forge feedstock maintainer entail?



The maintainers "job" is to:



- keep the feedstock updated by merging maintenance PRs from conda-forge's bots;

- keep the package updated by bumping the version whenever there is a new release;

- answer questions about the package on the feedstock issue tracker.



### 10. Why are there recipes already in the `recipes` directory? Should I do something about it?



When a PR of recipe(s) is ready to go, it is merged into `main`. This will trigger a CI build specially designed to convert the recipe(s). However, for any number of reasons the recipe(s) may not be converted right away. In the interim, the recipe(s) will remain in `main` until they can be converted. There is no action required on the part of recipe contributors to resolve this. Also it should have no impact on any other PRs being proposed. If these recipe(s) pending conversion do cause issues for your submission, please ping `conda-forge/core` for help.



### 11. **Some checks failed, but it wasn't my recipe! How do I trigger a rebuild?**



Sometimes, some of the CI tools' builds fail due to no error within your recipe. If that happens, you can trigger a rebuild by re-creating the last commit and force pushing it to your branch:



```bash

# edit your last commit, giving it a new time stamp and hash

# (you can just leave the message as it is)

git commit --amend

# push to github, overwriting your branch

git push -f

```



If the problem was due to scripts in the `staged-recipes` repository, you may be asked to "rebase" once these are fixed. To do so, run:

```bash

# If you didn't add a remote for conda-forge/staged-recipes yet, also run

# these lines:

# git remote add upstream https://github.com/conda-forge/staged-recipes.git

# git fetch --all

git rebase upstream/main

git push -f

```



### 12. My pull request passes all checks, but hasn't received any attention. How do I call attention to my PR?  What is the customary amount of time to wait?



Thank you very much for putting in this recipe PR!



This repository is very active, so if you need help with a PR, please let the

right people know. There are language-specific teams for reviewing recipes.



| Language        | Name of review team           |

| --------------- | ----------------------------- |

| python          | `@conda-forge/help-python`    |

| python/c hybrid | `@conda-forge/help-python-c`  |

| r               | `@conda-forge/help-r`         |

| java            | `@conda-forge/help-java`      |

| nodejs          | `@conda-forge/help-nodejs`    |

| c/c++           | `@conda-forge/help-c-cpp`     |

| perl            | `@conda-forge/help-perl`      |

| Julia           | `@conda-forge/help-julia`     |

| ruby            | `@conda-forge/help-ruby`      |

| other           | `@conda-forge/staged-recipes` |



Once the PR is ready for review, please mention one of the teams above in a

new comment. i.e. `@conda-forge/help-some-language, ready for review!`

Then, a bot will label the PR as 'review-requested'.



Due to GitHub limitations, first time contributors to conda-forge are unable

to ping conda-forge teams directly, but you can [ask a bot to ping the team][1]

using a special command in a comment on the PR to get the attention of the

`staged-recipes` team. You can also consider asking on our [Gitter channel][2]

if your recipe isn't reviewed promptly.

All apologies in advance if your recipe PR does not receive prompt attention.

This is a high volume repository and the reviewers are volunteers. Review times vary depending on the number of reviewers on a given language team and may be days or weeks. We are always

looking for more staged-recipe reviewers. If you are interested in volunteering,

please contact a member of @conda-forge/core. We'd love to have your help!
