# 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), 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.
If you already have `pyenv` and `pyenv-virtualenv` configured you can
take advantage of the `setup-env` tool in this repo to automate the
entire environment configuration process.
```console
./setup-env
```
Otherwise, follow the steps below to manually configure your
environment.
#### Installing and using `pyenv` and `pyenv-virtualenv` ####
On the Mac, we recommend installing [brew](https://brew.sh/). Then
installation is as simple as `brew install pyenv pyenv-virtualenv` and
adding this to your profile:
```bash
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init --path)"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
```
For Linux, Windows Subsystem for Linux (WSL), 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. Before running this ensure that you have
installed the prerequisites for your platform according to the
[`pyenv` wiki
page](https://github.com/pyenv/pyenv/wiki/common-build-problems).
On WSL you should treat your platform as whatever Linux distribution
you've chosen to install.
Once you have installed `pyenv` you will need to add the following
lines to your `.bash_profile` (or `.profile`):
```bash
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init --path)"
```
and then add the following lines to your `.bashrc`:
```bash
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
```
If you want more information about setting up `pyenv` once installed, please run
```console
pyenv init
```
and
```console
pyenv virtualenv-init
```
for the current configuration instructions.
If you are using a shell other than `bash` you should follow the
instructions that the `pyenv-installer` script outputs.
You will need to reload your shell for these changes to take effect so
you can begin to use `pyenv`.
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:
```console
cd skeleton-generic
pyenv virtualenv <python_version_to_use> skeleton-generic
pyenv local skeleton-generic
pip install --requirement requirements-dev.txt
```
#### Installing the pre-commit hook ####
Now setting up pre-commit is as simple as:
```console
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`.

CC0 1.0 Universal
Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator and
subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for the
purpose of contributing to a commons of creative, cultural and scientific
works ("Commons") that the public can reliably and without fear of later
claims of infringement build upon, modify, incorporate in other works, reuse
and redistribute as freely as possible in any form whatsoever and for any
purposes, including without limitation commercial purposes. These owners may
contribute to the Commons to promote the ideal of a free culture and the
further production of creative, cultural and scientific works, or to gain
reputation or greater distribution for their Work in part through the use and
efforts of others.
For these and/or other purposes and motivations, and without any expectation
of additional consideration or compensation, the person associating CC0 with a
Work (the "Affirmer"), to the extent that he or she is an owner of Copyright
and Related Rights in the Work, voluntarily elects to apply CC0 to the Work
and publicly distribute the Work under its terms, with knowledge of his or her
Copyright and Related Rights in the Work and the meaning and intended legal
effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not limited
to, the following:
i. the right to reproduce, adapt, distribute, perform, display, communicate,
and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or likeness
depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data in
a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation thereof,
including any amended or successor version of such directive); and
vii. other similar, equivalent or corresponding rights throughout the world
based on applicable law or treaty, and any national implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention of,
applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and
unconditionally waives, abandons, and surrenders all of Affirmer's Copyright
and Related Rights and associated claims and causes of action, whether now
known or unknown (including existing as well as future claims and causes of
action), in the Work (i) in all territories worldwide, (ii) for the maximum
duration provided by applicable law or treaty (including future time
extensions), (iii) in any current or future medium and for any number of
copies, and (iv) for any purpose whatsoever, including without limitation
commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes
the Waiver for the benefit of each member of the public at large and to the
detriment of Affirmer's heirs and successors, fully intending that such Waiver
shall not be subject to revocation, rescission, cancellation, termination, or
any other legal or equitable action to disrupt the quiet enjoyment of the Work
by the public as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason be
judged legally invalid or ineffective under applicable law, then the Waiver
shall be preserved to the maximum extent permitted taking into account
Affirmer's express Statement of Purpose. In addition, to the extent the Waiver
is so judged Affirmer hereby grants to each affected person a royalty-free,
non transferable, non sublicensable, non exclusive, irrevocable and
unconditional license to exercise Affirmer's Copyright and Related Rights in
the Work (i) in all territories worldwide, (ii) for the maximum duration
provided by applicable law or treaty (including future time extensions), (iii)
in any current or future medium and for any number of copies, and (iv) for any
purpose whatsoever, including without limitation commercial, advertising or
promotional purposes (the "License"). The License shall be deemed effective as
of the date CC0 was applied by Affirmer to the Work. Should any part of the
License for any reason be judged legally invalid or ineffective under
applicable law, such partial invalidity or ineffectiveness shall not
invalidate the remainder of the License, and in such case Affirmer hereby
affirms that he or she will not (i) exercise any of his or her remaining
Copyright and Related Rights in the Work or (ii) assert any associated claims
and causes of action with respect to the Work, in either case contrary to
Affirmer's express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or warranties
of any kind concerning the Work, express, implied, statutory or otherwise,
including without limitation warranties of title, merchantability, fitness
for a particular purpose, non infringement, or the absence of latent or
other defects, accuracy, or the present or absence of errors, whether or not
discoverable, all to the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without limitation
any person's Copyright and Related Rights in the Work. Further, Affirmer
disclaims responsibility for obtaining any necessary consents, permissions
or other rights required for any use of the Work.
d. Affirmer understands and acknowledges that Creative Commons is not a
party to this document and has no duty or obligation with respect to this
CC0 or use of the Work.

On the Mac, we recommend installing brew, https://brew.sh/. Then installation
is as simple as `brew install pyenv pyenv-virtualenv` and adding this to your
profile:
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

For Linux, Windows Subsystem for Linux (WSL), or on the Mac (if you don't want
to use "brew") you can use https://github.com/pyenv/pyenv-installer to install
the necessary tools. Before running this ensure that you have installed the
prerequisites for your platform according to the pyenv wiki page,
https://github.com/pyenv/pyenv/wiki/common-build-problems.
On WSL you should treat your platform as whatever Linux distribution you've
chosen to install.
Once you have installed "pyenv" you will need to add the following lines to
your ".bashrc":
export PATH="$PATH:$HOME/.pyenv/bin"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
