github_repo.revision = "v$SOME_ENV_VAR"

good morning, nice community!

Looks like there is no string extrapolation in the revision field of the github_repo:

.plzconfig

[BuildEnv]
FLATBUFFERS-VERSION = 24.3.25

BUILD

github_repo(
  name = "flatbuffers_src",
  repo = "google/flatbuffers",
  revision = "v$FLATBUFFERS_VERSION",
)

For the uninitiated like me, this solution will work:

.plzconfig

[Buildconfig]
FLATBUFFERS-VERSION = 24.3.25

BUILD

github_repo(
  name = "flatbuffers_src",
  repo = "google/flatbuffers",
  revision = f"v{CONFIG.FLATBUFFERS_VERSION}",
)
