# Welcome #
We're so glad you're thinking about contributing to this open source
project! If you're unsure or afraid of anything, just ask or submit
the issue or pull request anyway. The worst that can happen is that
you'll be politely asked to change something. We appreciate any sort
of contribution, and don't want a wall of rules to get in the way of
that.
Before contributing, we encourage you to read our CONTRIBUTING policy
(you are here), our [LICENSE](LICENSE.md), and our
[README](README.md), all of which should be in this repository.
## Issues ##
If you want to report a bug or request a new feature, the most direct
method is to [create an
issue](https://github.com/cisagov/skeleton-generic/issues) in this
repository. We recommend that you first search through existing
issues (both open and closed) to check if your particular issue has
already been reported. If it has then you might want to add a comment
to the existing issue. If it hasn't then feel free to create a new
one.
## Pull requests ##
If you choose to [submit a pull
request](https://github.com/cisagov/skeleton-generic/pulls), you will
notice that our continuous integration (CI) system runs a fairly
extensive set of linters and syntax checkers. Your pull request may
fail these checks, and that's OK. If you want you can stop there and
wait for us to make the necessary corrections to ensure your code
passes the CI checks.
If you want to make the changes yourself, or if you want to become a
regular contributor, then you will want to set up
[pre-commit](https://pre-commit.com/) on your local machine. Once you
do that, the CI checks will run locally before you even write your
commit message. This speeds up your development cycle considerably.
### Setting up pre-commit ###
There are a few ways to do this, but we prefer to use
[`pyenv`](https://github.com/pyenv/pyenv) and
[`pyenv-virtualenv`](https://github.com/pyenv/pyenv-virtualenv) to
create and manage a Python virtual environment specific to this
project.
#### Installing and using `pyenv` and `pyenv-virtualenv` ####
On the Mac, installation is as simple as `brew install pyenv
pyenv-virtualenv` and adding this to your profile:
```bash
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
```
For Linux you will need to find a package for your particular distro,
or follow the manual instructions
[here](https://github.com/pyenv/pyenv#installation) and
[here](https://github.com/pyenv/pyenv-virtualenv#installation). Then
you will need to add the same bit above to your profile.
For a list of Python versions that are already installed and ready to
use with `pyenv`, use the command `pyenv versions`. To see a list of
the Python versions available to be installed and used with `pyenv`
use the command `pyenv install --list`. You can read more
[here](https://github.com/pyenv/pyenv/blob/master/COMMANDS.md) about
the many things that `pyenv` can do. See
[here](https://github.com/pyenv/pyenv-virtualenv#usage) for the
additional capabilities that pyenv-virtualenv adds to the `pyenv`
command.
#### Creating the Python virtual environment ####
Once `pyenv` and `pyenv-virtualenv` are installed on your system, you
can create and configure the Python virtual environment with these
commands:
```bash
cd skeleton-generic
pyenv virtualenv <python_version_to_use> skeleton-generic
pyenv local skeleton-generic
pip install -r requirements-dev.txt
```
#### Installing the pre-commit hook ####
Now setting up pre-commit is as simple as:
```bash
pre-commit install
```
At this point the pre-commit checks will run against any files that
you attempt to commit. If you want to run the checks against the
entire repo, just execute `pre-commit run --all-files`.
