# Config file for Powerlevel10k with the style of Pure (https://github.com/sindresorhus/pure).
#
# Differences from Pure:
#
#   - Git:
#     - `@c4d3ec2c` instead of something like `v1.4.0~11` when in detached HEAD state.
#     - No automatic `git fetch` (the same as in Pure with `PURE_GIT_PULL=0`).
#
# Apart from the differences listed above, the replication of Pure prompt is exact. This includes
# even the questionable parts. For example, just like in Pure, there is no indication of Git status
# being stale; prompt symbol is the same in command, visual and overwrite vi modes; when prompt
# doesn't fit on one line, it wraps around with no attempt to shorten it.
#
# If you like the general style of Pure but not particularly attached to all its quirks, type
# `p10k configure` and pick "Lean" style. This will give you slick minimalist prompt while taking
# advantage of Powerlevel10k features that aren't present in Pure.
