Decanonicalize labels emitted by {a,c,}query if possible
Browse files Browse the repository at this point in the history
Uses the newly added `PackageIdentifier#getDisplayForm` to turn labels
in the output of query, aquery, and cquery into the most concise
representation that allows them to be resolved from the context of the
main repository.

Closes bazelbuild#16483.
