Function: bazel--target-location

bazel--target-location is a natively compiled function defined in bazel.el.

Signature

(bazel--target-location REPOSITORY PACKAGE TARGET)

Documentation

Return an ‘xref-location’ for a Bazel target.

The target is in the repository with root directory REPOSITORY and the package PACKAGE. Its local name is TARGET. If no target was found, return nil. This function uses heuristics to find the target; in particular, it assumes that a target that looks like a valid file target is indeed a file target.
