Win10 Build Issue

[ValeTheVioletMote]

Apologies if this is entirely ignorant, new to Haskell as of this project. Big fan of Date and wanted to try this out.

Actively working through my problems, but I did come across this:

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for project-m36-0.7:
    parser-combinators needed, but the stack configuration has no specified version  (latest
                       matching version is 1.2.1)
needed since project-m36 is a build target.

Some different approaches to resolving this:

  * Consider trying 'stack solver', which uses the cabal-install solver to attempt to find some
    working build configuration. This can be convenient when dealing with many complicated
    constraint errors, but results may be unpredictable.

  * Recommended action: try adding the following to your extra-deps
    in C:\gerk\project-m36\stack.ghc8.0.yaml:

parser-combinators-1.2.1@sha256:16c3490e007ec10b1255a2b36fb483d000156d555269107131241d9e0fa96412

Plan construction failed.

This is a fresh clone as of an hour ago.

I'll try the suggestions. Just unsure of what I'm doing and if I missed something obvious.

I installed the full Haskell Platform, which is why I believe I can skip mysys. If that's my problem, please let me know.

[ValeTheVioletMote]

Oh, the docs said to use stack.ghc8.0.yaml, but now I see stack.ghc8.6.yaml ... Giving that a go.

[ValeTheVioletMote]

I cannot skip msys. Running with stack --stack-yaml stack.ghc8.6.yaml build worked.

Possible that the docs need updated. Otherwise, feel free to close.

[agentm]

Sorry about the build issues, but thanks for putting in the extra effort to get Project:M36 working. I will certainly fix the documentation.

I have not been particularly good about making binary releases because I can't gauge if there would be interest. Given the option to download some console-based binaries, would you have chosen to download the binary in lieu of building from source?

I ask because I suspect that the majority of the current user base is likely comfortable with Haskell and using Project:M36 as a library rather than a TutorialD platform, but I would like to expand the base further. What do you think?

[ValeTheVioletMote]

@agentm

No problem at all.. Gave me a little experience with Haskell's tooling.

I only bothered with the Windows build because I thought there was a GUI. (And if there is one, forgive me, I didn't see it...)

I would've downloaded the binary first, correct. I noticed there was one out there, but it was 800+ commits behind master. Fair assumption that it probably wasn't up to date, I'd say...

As for your last question, I don't know how much of a userbase I represent. I've just been walking down the list of https://en.wikipedia.org/wiki/D_(data_language_specification)#Implementations looking to see if anyone has come up with an option where I can connect to their impl via something analogous to a *dbc driver.

I was drawn in by "Project:M36 can be used as an in-process or remote DBMS." Looks like that's Haskell -> Haskell though, as you mentioned? Which is perfectly fine. I may be a niche or looking for a miracle. My best bet may be to see what I can do with Reldb, as the Tutorial D there seems more robust (I could absolutely be wrong.. this just seems very limited: https://github.com/agentm/project-m36/blob/master/docs/tutd_tutorial.markdown#extend)

This project seems fantastic and I wish you (and anyone else supporting D) the best.

Edit: I now see you have a major advantage over Rel with how you handle the NULL question. https://github.com/agentm/project-m36/blob/master/docs/on_null.markdown What a brilliant idea. This encourages me more to see what I can do with PM36.

[ValeTheVioletMote]

On that note, sounds like I need to check out https://github.com/agentm/project-m36/blob/master/docs/websocket_server.markdown though both of the example links result in 404. Looks like the docs need the paths updated.

[agentm]

Thanks for the reports, @ValeTheVioletMote. Indeed, the simple websocket web interface is a quick way to be able to use a GUI with Project:M36 and the JSON-based websocket API is great for getting data in-and-out of Haskell-land.

I patched the documentation so that the websocket links are no longer broken and that the intro material suggests using a later version of GHC.

If you wish to discuss Project:M36's design decisions, I invite you to join us on IRC: irc.freenode.net#project-m36. Optionally, you can join using freenode's web-based client.
