Freeing Hierarchy from any dependence on streaming libraries #8

Closed jwiegley closed 6 years ago

jwiegley commented 6 years ago

Hi @capitanbatata,

I think I'd like to take back maintenance of hierarchy, since I'm going to be using it a fair bit in the hnix project. I'm also going to generalize this library away from any dependence on a particular streaming library, instead choosing the simpler LogicT transformer as the foundation and implementation of ListT. See pull request #7 which implements this change. I have a supporting PR for pipes-files coming shortly. I will likely also create a new files like library that doesn't need pipes, which is really overkill for the problem we're solving.

Hi John, sure. The reason why I needed hierarchy was to be able to put another package (argon) which depended on pipes-files. After trying to update pipes-files I discover that this package could not be built on windows (a requirement of my current project). So I removed the pipes-files dependency from argon.

All in all feel free to remove me as maintainer, and I'm happy to see that some work is taking place around file streaming libraries for Haskell.

@capitanbatata Ah, fair enough. I wonder if the new formulation of this code on LogicT would indeed work on Windows, using unix-compat?

dnadales commented 6 years ago

That'd be awesome, since such library would be very useful for us. I'll keep an eye on these packages. Thanks!

@capitanbatata We don't even need a dependence on logict! All that was needed was MonadPlus. See: http://www.haskellforall.com/2014/11/how-to-build-library-agnostic-streaming.html

I'm going to apply this same logic to pipes-files to make hierarchy-files.
