# 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 (or on the Mac, if you don't want to use `brew`) you can use
|
|
[pyenv/pyenv-installer](https://github.com/pyenv/pyenv-installer) to
|
|
install the necessary tools. When you are finished you will need to
|
|
add the same two lines 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`.
