# We suport two sqlite implementations: modernc and mattn. Each implementation
# has a corresponding sqlite_<impl>.go "driver" in private/storage/db. Which
# driver gets compiled and linked is controled by a go build tag: sqlite_mattn
# or sqlite_modernc. Those are specified on the command line
# with "--define gotags=sqlite_mattn" or "--define gotags=sqlite_modernc"
# (see the build options in .bazelrc).
#
# Unfortunately Gazelle needs to be given these tags explicitly via the builtags
# attribute. So, to ensure consistency we have to translate our two gotags into
# build_tags. To that end, we create two config_setting flags that are
# set in response to matching the gotags value and use them to select the relevant
# tag for gazelle. (The "define_value" attribute of config_setting doesn't define
# anything. It matches a key-value pair from "--define").
#
# This is simplistic but the complete, by-the-everchanging-bazel-book, solution
# is ludicrously complicated. Go there if and when needed.
