My Notes

What are some of the low-friction ways of using Haskell?

• Pandoc – add custom elements, extract metadata from documents.
• Hakyll – build custom site renderers.
• Shake – build system where Make isn’t sufficient.

If you get can't load .so/.DLL for when installing cabal package: put shared: True in ~/.cabal/config

Cabal

• cabal - the simple guide
• (2) Introduction to Cabal - YouTube

Sandbox:

    cabal sandbox init
    cabal init #to init a new proj.

remember to export HASKELL_PACKAGE_SANDBOX=.cabal-sandbox/x86_64-osx-ghc-7.6.3-packages.conf.d inside the cabal sandbox.

cd myproj
stack init
brew install zmq
