# footnotes

## Description

Featured on [wpmudev](http://premium.wpmudev.org/blog/12-surprisingly-useful-wordpress-plugins-you-dont-know-about/) --- cheers for the review, folks!

**footnotes** aims to be the all-in-one solution for displaying an automatically generated list of references on your Page or Post. The Plugin ships with a set of defaults while also empowering you to control how your footnotes are being displayed.

**footnotes** gives you the ability to display well-formatted footnotes on your WordPress Pages and Posts — those footnotes we know from offline publishing.

## Getting Started

1. Read the contributing guidelines
1. Clone this repository (`git clone git@github.com:markcheret/footnotes.git`)
  - We recommend that you use [VVV](https://varyingvagrantvagrants.org/) for your development environment
1. Install [Composer](https://getcomposer.org/download/), if you don't have it already
1. Install dependencies (`composer install`)
1. Create a new branch from `main` (`git checkout -b <your-descriptive-branch-name>`)
1. When you're finished, commit your changes to the remote version of your branch
   and submit a [pull request](https://github.com/markcheret/footnotes/pulls).

## Checking WP Coding Standard Compliance

1. Run PHP_CodeSniffer on the file(s) you want to check (`./vendor/bin/phpcs --standard="WordPress" --colors --encoding=utf-8 -n -p <file(s)>`)
1. (If applicable) run the PHP Code Beautifier and Formatter to attempt to automatically fix any errors (`./vendor/bin/phpcbf --standard="WordPress" --encoding=utf-8 -p <file(s)>`)
  - Add the `-n` flag to ignore warnings (i.e., show only errors)
  - Add the `-s` flag to show sniff codes (used for disabling errors in the code with `phpcs disable:<sniff code>` — MAKE SURE THAT YOU HAVE `phpcs enable` AT THE EARLIEST POINT POSSIBLE, and provide a justification for disabling the sniff code)
  - You can run either across the entire project by adding the argument `--ignore=*/vendor/*` and targetting the file `./**/*.php`
    - You may have to enable double-wildcards in your console first (`shopt -s globstar`)

## Updating Documentation

1. Install [phpDocumentor](https://phpdoc.org/)
1. Run it (`phpDocumentor -d . -t docs`)
