# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of
experience, nationality, personal appearance, race, religion, or sexual identity
and orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
- Using welcoming and inclusive language
- Being respectful of differing viewpoints and experiences
- Gracefully accepting constructive criticism
- Focusing on what is best for the community
- Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
- The use of sexualized language or imagery and unwelcome sexual attention or
advances
- Trolling, insulting/derogatory comments, and personal or political attacks
- Public or private harassment
- Publishing others' private information, such as a physical or electronic
address, without explicit permission
- Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, or to ban temporarily or permanently any
contributor for other behaviors that they deem inappropriate, threatening,
offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at me@fnando.com. The project team will
review and investigate all complaints, and will respond in a way that it deems
appropriate to the circumstances. The project team is obligated to maintain
confidentiality with regard to the reporter of an incident. Further details of
specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage],
version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

# Contributing
Once you've made your great commits (include tests, please):
1. Fork this repository
2. Create a topic branch - `git checkout -b my_branch`
3. Push to your branch - `git push origin my_branch`
4. Create a pull request
That's it!
Please respect the indentation rules and code style. And use 2 spaces, not tabs.
And don't touch the version thing or distribution files; this will be made when
a new version is going to be released.

# CPF
[](https://travis-ci.org/fnando/cpf)
[](https://www.npmjs.com/package/@fnando/cpf)
This package does some
[CPF](http://en.wikipedia.org/wiki/Cadastro_de_Pessoas_F%C3%ADsicas) magic. It
allows you to create, validate and format CPF documents.
**HINT:** Check out the CNPJ counter part available at
<https://github.com/fnando/cnpj>.
## Installation
This lib is available as a NPM package. To install it, use the following
command:
```
npm install @fnando/cpf --save
```
If you're using Yarn (and you should):
```
yarn add @fnando/cpf
```
## Usage
```js
// Node.js-specific
const cpf = require("@fnando/cpf/commonjs");
// @import
import * as cpf from "@fnando/cpf"; // import the whole library
import { isValid as isValidCpf } from "@fnando/cpf"; // import just one function
// import via <script>; the lib will available as window.CPF
// <script src="cpf.js"></script>
cpf.isValid("532.820.857-96");
//=> true
cpf.isValid("53282085796");
//=> true
cpf.strip("532.820.857-96");
//=> 53282085796
cpf.format("53282085796");
//=> 532.820.857-96
cpf.generate(true); // generate formatted number
//=> 838.684.734-40
cpf.generate(); // generate unformatted number
//=> 72777632898
```
On the web, without transformation, just use `web/cpf.min.js`.
### Strict Validation
By default, validations will strip any characters you provide. This means that
the following is valid, because only numbers will be considered:
```js
cpf.isValid("101#688!!!!!!542......36");
//=> true
cpf.strip("101#688!!!!!!542......36");
//=> 10168854236
```
If you want to strict validate strings, use the following signature:
```js
cpf.isValid(number, strict);
```
The same example would now return `false`:
```js
cpf.isValid("101#688!!!!!!542......36", true);
//=> false
```
