Hi Adam,
I was able to get what I need using your information. Thanks so much for
your help!
#!/usr/bin/env bash
cabal update
mkdir -p deps
_project="$(echo *.cabal | cut -d '.' -f 1)"
pushd deps > /dev/null
cp ../$_project.cabal ./
projects() {
cabal install $_project --dry-run | grep hw- | grep -v
"^${_project}-[0-9]\\+\\.[0-9]\\+\\.[0-9]\\+\\.[0-9]\\+$"
}
for x in $(projects); do
stack unpack $x
done
rm ./$_project.cabal
popd > /dev/null
Cheers,
-John
