add ability to specific abstract resolver in stack.yaml #6556

Closed evan0greenup closed 2 months ago

evan0greenup commented 2 months ago

Beside a concrete resolver specification like lts-22.7 or nightly-2024-04-19, it would be nice to make the resolver specified to lts or nightly which use latest lts-* or nightly-* at the moment when stack.yaml is accessed by the stack command.

@evan0greenup, thanks for reporting. That is, in fact, a long-standing and deliberate design decision, explained here: https://docs.haskellstack.org/en/stable/GUIDE/#snapshots-and-changing-your-compiler-version. This also duplicates #1878, so I am going to close it as a duplicate.
