This script is meant to help with managing releases. Usage:
|
|
|
|
$0 snapshot SHA PREFIX
|
|
Prints the snapshot line for commit SHA as a release candidate for
|
|
version PREFIX. For example:
|
|
|
|
$ $0 snapshot cc880e2 0.1.2
|
|
cc880e290b2311d0bf05d58c7d75c50784c0131c 0.1.2-snapshot.20200513.4174.0.cc880e29 SPLIT_RELEASE
|
|
|
|
Any non-ambiguous git commit reference can be given as SHA.
|
|
|
|
$0 check
|
|
Checks that each line of the LATEST file is well-formed.
|
|
|
|
Any other invocation will display this help message.
|
|
|
|
For further details, see the documentation in /release/RELEASE.md
