  • [ANN] Haskell Streamly 0.9.0 Release!

    https://github.com/composewell/streamly/issues/1307 seems related, but it was a long time ago. We weren't heavy users anyway, so our streaming philosophy is now "conduit if it's simple and plugging into a conduit-using library, streaming if you're doing complicated things".

    We are glad to announce streamly 0.9.0 release. streamly-0.9.0 and streamly-core-0.1.0 have been available on Hackage for some time now, you can find reference documentation and some guides on https://streamly.composewell.com as well. The website also has functionality to search across multiple streamly packages.

    I want to like streamly, but the API is so huge, yet I feel like I'm doing things on a too low level of abstraction. (And as long as it needs a ghc plugin I doubt it'll become the de facto standard.) Though maybe I just haven't used it enough. It does have great docs at https://streamly.composewell.com/ and they seem to be taking both performance, dependency weight and API design quite seriously.
