TL;DR:
cabal install containers # import Data.Map.Lazy
I have been enjoying the series from Jekor over on youtube.
After checking out his example code from github I have been able to compile along with the music... until ep07
./redo redo
redo.do: 1: redo.do: redo-ifchange: not found
redo.hs:5:8:
Could not find module `Data.Map.Lazy'
Use -v to see a list of the files searched for.
Redo script exited with non-zero exit code: 1
"Ah ha!" I thought to myself
cabal install Data.Map.Lazy
Nope. Off to Hoogle I go and after a while I worked out that what I needed was:
cabal install containers
but it was not Hoogle, but Google that clued me in.
cabal list|grep -i Map|grep -i Lazy
didn't help. Now that I know the answer it is quite easy to find:
hoogle --info Data.Map.Lazy|grep 'From package'|awk '{print $NF}'
and even create a general Haskell module installer:
#!/bin/sh
#cabalModuleInstall
cabal install $(hoogle --info $1 | grep 'From package'|awk '{print $NF}')
cabal install containers # import Data.Map.Lazy
