# A light theme showing only minimal information in colour:
|
|
|
# - Current directory, optionally prefixed with the user and host
|
|
|
# - Git repo and branch, with markers for staged and unstaged changes.
|
|
|
# - Battery change meter on the right, with colour based on charge,
|
|
|
# and only appearing when battery is below 90% charge.
