# This is equivalent to our old logic of "use a value in package.json" for the
|
||
|
|
# following reasons:
|
||
|
|
#
|
||
|
|
# 1. Whenever we updated the package.json we ALSO pushed a tag with the same
|
||
|
|
# version.
|
||
|
|
# 2. Whenever we _reverted_ a bump all we actually did was push a commit that
|
||
|
|
# deleted the tag and changed the version number back.
|
||
|
|
#
|
||
|
|
# The only difference in the "git describe" technique is that technically a
|
||
|
|
# commit can "change" its version number if a tag is created / removed
|
||
|
|
# retroactively. i.e. the first time a commit is pushed it will be 1.2.3
|
||
|
|
# and after the tag is made rebuilding the same commit will result in it being
|
||
|
|
# 1.2.4.
