# version-from-branch.sh — derive a semver-compliant version string from a branch name.
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# version-from-branch.sh [BRANCH]
|
||
|
|
#
|
||
|
|
# If BRANCH is omitted the current git branch is used. Outputs a version, or blank if the version isn't supplied.
|
||
|
|
#
|
||
|
|
# This *will not* take tags into account, and will never deliver a "clean" (major.minor.patch) version.
