# AdGuard Home Version Generation Script
|
|
#
|
|
# This script generates versions based on the current git tree state.
|
|
# The valid output formats are:
|
|
#
|
|
# * For release versions, "v0.123.4". This version should be the one
|
|
# in the current tag, and the script merely checks, that the current
|
|
# commit is properly tagged.
|
|
#
|
|
# * For prerelease beta versions, "v0.123.4-b.5". This version should
|
|
# be the one in the current tag, and the script merely checks, that
|
|
# the current commit is properly tagged.
|
|
#
|
|
# * For prerelease alpha versions (aka snapshots),
|
|
# "v0.123.4-a.6+a1b2c3d4".
|
|
#
|
|
# BUG(a.garipov): The script currently can't differentiate between beta
|
|
# tags and release tags if they are on the same commit, so the beta tag
|
|
# **must** be pushed and built **before** the release tag is pushed.
|
|
#
|
|
# TODO(a.garipov): The script currently doesn't handle release branches,
|
|
# so it must be modified once we have those.
