Jenkinsfile idiosynchrasies with escaping and quotes
node {
echo 'Results included as an inline comment exactly how they are returned as of Jenkins 2.121, with $BUILD_NUMBER = 1'
echo 'No quotes, pipeline command in single quotes'
sh 'echo $BUILD_NUMBER' // 1
echo 'Double quotes are silently dropped'
sh 'echo "$BUILD_NUMBER"' // 1
echo 'Even escaped with a single backslash they are dropped'
sh 'echo \"$BUILD_NUMBER\"' // 1
echo 'Using two backslashes, the quotes are preserved'
sh 'echo \\"$BUILD_NUMBER\\"' // "1"

A simple installation guide for i3-gaps

Installing i3-gaps

Dependencies

i3-gaps has some packages that are required for it to work so install these things:

sudo apt install libxcb1-dev libxcb-keysyms1-dev libpango1.0-dev libxcb-util0-dev libxcb-icccm4-dev libyajl-dev libstartup-notification0-dev libxcb-randr0-dev libev-dev libxcb-cursor-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev autoconf xutils-dev libtool automake

You also need to install libxcb-xrm-dev, but I got Unable to locate package libxcb-xrm-dev when trying to install from the apt repositories on Ubuntu 16.04. If this happens to you, just install it from source using these commands:

mkdir tmp
[[constraint]]
name = "k8s.io/api"
version = "kubernetes-1.11.0"
[[constraint]]
name = "k8s.io/apimachinery"
version = "kubernetes-1.11.0"
[[constraint]]
name = "k8s.io/client-go"
