CamelCase <--> snake_case conversion with jq

tl;dr

I provide you with 3 jq lib functions that will help you in converting between snake_case and CamelCase.

I want to change keys in my json from camelcase to snake_case.

Build Only When Necessary

In testing environments, it is not always useful repeating tasks which can cost developers valuable time. Within a project its safe to assume that not all files are changed, so why rebuild?

This tutorial outlines a method to reduce unnecessarly build steps. Use your best judgement of course. It might be useful to add in a build on occassion to ensure third party dependencies are available and will not disrupt a production deployment.

Jenkins Setup

The git plugin in Jenkins provides several useful environment variables which can be used to avoid build tasks. Make sure you setup the git plugin before going any further.

jq will sort (-S) the whole file (.) and compare STDOUT (<()) with diff

diff <(jq -S . A.json) <(jq -S . B.json)

Slow sudo on macOS 10.12.4

On my iMac 5k (iMac15,1) since the update on macOS 10.12.4 sudo is very slow. It takes about 5 minutes to the password prompt.

The problem is not on my MacBook Pro (MacBookPro13,1) with the same operating system 10.12.4.

With 10.12.3. I had no problems on the iMac.
