Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional, and may contain IDs of the task / user story we are changing the code for (e.g. SELL-123)

Example

xpepper

(
relativeDir=""
while [[ ! -d ".vagrant" ]]; do
  if [[ "$(pwd)" == "/" ]]; then
    echo "Not a valid path"
    exit
  fi

  relativeDir="${PWD##*/}/$relativeDir"
  cd ..
