PHPCS Standards - The XpBar edition

These are my personal phpcs standards, a collection of sniffs and rulesets from others, and some I've written myself (because, why not?).

PREFACE

This repo contains both my own work, and the works of Squiz Labs and Slevomat, and uses phpcs Sniffs written by multiple other parties.

Repositories for sniffs not included in the default set provided by Squiz Labs:

Before running the install or update scripts, make sure:

you can clone git objects via the command line with git clone
which phpcs should return a path if you have previously installed phpcs (if you have not installed phpcs already, the install script will install it globally for you.)
you have a global installation of composer

All you should need to get started is the install script; simply

Clone the Repo
cd into the directory
(optional) cat install.sh -- check the source code, make sure it's safe!
chmod +x ./install.sh
run ./install
(optional) run ./update to update! (re-clones the repos and re-installs sniffs)

If the above doesn't work for you, or if you have phpcs installed but which phpcs returns a blank string, try the below.

find your desired installation of phpcs. If you already have it installed, find where the bin file symlinks to - this is the install directory.
in the installation directory, find the Standards folder under src - for my global composer install, it's under ~/.composer/vendor/squizlabs/php_codesniffer/src/Standards.
Clone each of repos listed in the preface above (slevomat/coding-standard, hostnet/phpcs-tool, sirbrillig/variable-analysis) and find the folder that contains a folder called Sniffs. Unless the repos have changed since I've wrote this, this folder should be the top namespace for the project (ie. SlevomatCodingStandard, Hostnet and VariableAnalysis) and should either be in the root of the project or under a src folder.
copy the folders containing Sniffs for each repo into the squizlabs/php_codesniffer/src/Standards folder (ie. copy SlevomatCodingStandard, Hostnet and VariableAnalysis).
finally, copy this repo's ruleset and sniffs (the entire XpBar folder) to squizlabs/php_codesniffer/src/Standards.

update your editor config to point to your global phpcs installation - which phpcs and to use the XpBar standard as the default
(optional) run phpcs --config-set warning_severity 3 to include warnings about return types, which I've marked with a lower priority until I move them into their own sniffs
