before commit, check if puppet files have valid syntax
#!/bin/sh
# this hook aborts commits which contain invalid puppet syntax
errors=0
# get all files in commit, use awk to get file name only, use grep to get puppet files only
files=$(git diff --cached --name-status | awk '$1 != "D" { print $2 }' | grep "\.pp")
# if you are committing .pp files
if [[ "$files" ]]; then

My personal preference for ruby style
# add indent after access modifier e.g. private
Layout/IndentationConsistency:
EnforcedStyle: indented_internal_methods # previously rails style
# Use double quotes by default, common in large projects including rails
# https://anti-pattern.com/always-use-double-quoted-strings-in-ruby
Style/StringLiterals:
Enabled: true
EnforcedStyle: double_quotes

Last active November 12, 2020 14:27
javascript abuse, self describing code because it is itself naff. A coworker shared the fail example with me so I expanded a bit.
// example: https://jsfiddle.net/conorsheehan1/vqdfsh31/
// runnable in any browser console
// fail (coworker showed me this one)
(![] + [])[+[]] + (![] + [])[+!+[]] + ([![]] + [][[]])[+!+[] + [+[]]] + (![] + [])[!+[] + !+[]];
// Naff
((![] + [][[]]) + [])[+[]] + ((![] + [][[]]) + [])[+!+[]] + (![] + [])[+[]] + (![] + [])[+[]];
// Nooo
