j-mie6 / rangeset Goto Github PK

Hi @j-mie6

Sorry to be a pain but I've just tried setting up a fresh project to use Parsley and I'm running into a build error on this rangset dependency. Bashed my head against it for a while and I just can't fathom what is going wrong! Any help / ideas would be much appreciated.

Error log from cabal:

Preprocessing library for rangeset-0.0.1.0..
Building library for rangeset-0.0.1.0..

src\ghc\Data\RangeSet\Internal\Types.hs:1:7: error:

  |       ^

I'm guessing those error locations are garbage because they aren't accounting for whatever the preprocessor might be doing?

Platform: Windows, 64-bit, AMD

I installed GHC/etc. using GHCUp:
ghc: 9.2.7
base: 4.16.4.0
cabal: 3.6.2.0

Packages from Hackage:
parsley: 2.0.0.0
rangeset: 0.0.1.0

Please let me know what additional info would be useful.

Hi, this seems like a nice library and I would like to use it, but I have no idea what runtime behavior to expect because the documentation makes no mention of time complexities and neither is the internal data structure described anywhere.
Please consider documenting performance characteristics of operations in the Haddocks.
