Hi all,
getSwiftFullVersion output must take account stdlib revsion?
How about get the revision hash from the Swift repository
*excluding* stdlib/, test/ and validation-test/ directories.
git log -1 --pretty=format:%H -- \
. \
:(exclude)stdlib \
:(exclude)test \
:(exclude)validation-test
Instead of,
git log -1 --pretty=format:%H
Or more specifically, just include only "compiler" related directories:
git log -1 --pretty=format:%H -- include/ lib/ tools/
I've wrote PoC code
