symlinkghc - Symbolically link the ghc tools provided by the global stack resolver into PATH

symlinkghc

#!/bin/sh
# Usage: symlinkghc
# Symbolically link the ghc tools provided by the global stack resolver
# (ghc ghci runghc runhaskell ghc-pkg haddock hp2ps hpc hsc2hs,
# ~/.stack/global-project/stack.yaml)
# into ~/.local/bin, so that they are always available at the command
# line for quick experiments. ~/.local/bin should be in your PATH.
# Similarly named executables/links in that directory will be overwritten.
# GHC will be downloaded if needed, eg if you just updated the global stack resolver.
# Caveat: these will see only the ghc package db by default, not new packages you have installed.
