Changing the bounds on dependencies on Hackage

[fixingcredit]

Hi @alpmestan,

I wanted to use servant-ede-0.51 with servant-0.7 and aeson-0.11.2 but I could not find a build plan due to the bounds set on Hackage. I was able to download the source and include it in my project and everything works fine.

The .cabal file does not seem specify any upper bounds so not sure how the Hackage dependencies are determined. It will be great if you could update Hackage when you get a chance (unless there are specific reasons for the restriction). It will be nice to include it as a separate library than inside my source code.

Thanks!

Hi @fixingcredit Thanks for the report. I've modified the bounds on hackage, can you try again now?

[fixingcredit]

Thanks, @alpmestan. I still get an error even though Hackage website seems to be updated. I am using stack and it could a caching issue? I will try again tomorrow.

Sorry I missed http-types and semigroups in my previous note. I see aeson, servant and vector bounds are updated on Hackage.

--  Failure when adding dependencies:
      aeson: needed (>=0.8 && <0.10), 0.11.2.0 found (latest applicable is 0.9.0.1)
      http-types: needed (>=0.8 && <0.9), 0.9 found (latest applicable is 0.8.6)
      semigroups: needed (>=0.16 && <0.17), 0.18.1 found (latest applicable is 0.16.2.2)
      servant: needed (>=0.4 && <0.6), 0.7.1 found (latest applicable is 0.5)
      vector: needed (>=0.9 && <0.11), 0.11.0.0 found (latest applicable is 0.10.12.3)
    needed for package: servant-ede-0.5.1

Are you trying to install it via cabal? If yes, have you issued a cabal update before re-trying to install servant-ede?

I am using stack and I did stack update before building. After giving it a night's rest, the cache has propagated. The new error is expected as the dependencies on Hackage has stricter bounds on these two

--  Failure when adding dependencies:
      http-types: needed (>=0.8 && <0.9), 0.9 found (latest applicable is 0.8.6)
      semigroups: needed (>=0.16 && <0.17), 0.18.1 found (latest applicable is 0.16.2.2)
    needed for package: servant-ede-0.5.1

Is it possible to update those two bounds as well -- it works for me with those versions listed but I don't really know if there are other issues to consider.

Thanks very much!

[alpmestan]

Oops, forgot these two. I've updated the bounds for them. As far as I can tell, servant-ede should build fine with all these updated bounds but let me know if you encounter any problem (i.e if servant-ede's code needs fixing)!

Cheers =)

Thank you, it works now! I have an issue with my template not picking up my field but that's probably an EDE issue and I will investigate further or report a reproducible example. I will close this issue.

[alpmestan]

Feel free to open an issue for your problem, even if it's not related to servant-ede itself, I might be able to help.

Thanks for offering to help!

I was able to find out the root cause of the issue -- I did not realize ToObject uses ToJSON's field names and since I was using fieldLabelModifier inside ToJSON instance, I had to use the names post modification.
