You have misunderstood me. I know cabal - with and without sandbox. I said am amazed that sandboxes or nix tools are necessary in Haskell _at all_ while every other language which uses a package manager has one that works out of the box without any hassle and without any sandbox tricks. > Nix and NixOS are two completely unrelated projects, that not even be recommendable in a development environment. Other Haskell de…

I have programmed professionally with C, C++, Go, Haskell, Java, Javascript, Python, and Ruby. While this is not "every other language", I feel it's a sufficient cross-section to be useful for the purposes of this thread. Trying to do any sort of open-source development without…

> Modularity is something which Haskell people simply do not take seriously Plus, the build/module/packaging/dependency resolution story, even when doing all the recommended best practices involving sandboxing Cabal and leveraging Nix are just plain embarrassing. There are so many smart Haskell people. I don't understand how any of them could consider this clusterf*ck to be remotely acceptable.

When using python I use virtualenv. When using Haskell I use cabal sandbox. I rarely have any problems, why is it a clusterf*ck?

In Haskell, sandboxes usually force you to rebuild stuff which you have already built over and over. Anyway, sandboxes are pointless hacks which wouldn't be necessary if things had been done properly from the beginning. They are like Node.JS ... yes, it enables you to develop with JavaScript on the server, but how the hell did you end up with using JavaScript in the first place?!

Sandboxes aren't pointless hacks which shouldn't be necessary. It's a lot more difficult for static languages to get right, and solutions like Maven have had tons of work put into them. You say "if things had been done properly from the beginning" implying you know some mistakes that were made. What mistakes were made in the beginning? Do you have any ideas how the problems cabal has could have been avoided? There ar…
