work-on fails for basic cabal package #67

Closed lally closed 8 years ago

lally commented 8 years ago

Hi, I'm trying to get a basic cabal package together as a starting point for reflex. I get this, but don't know what JSON string it's looking for.

Ok, I sorted this out partially.

The problem is that I ran update, and it overwrote the various .json files with non-json.

nix-prefetch-git doesn't put out json, it puts out:

if test -n "$hash"; then
    echo "{"
    echo "  url = \"$url\";"
    echo "  rev = \"$fullRev\";"
    echo "  $hashType = \"$hash\";"
    echo "}"
fi

(quoting from /nix/store/hlm20i19xij48v7yqxh1by731xvgxf3i-nix-prefetch-git/bin/.nix-prefetch-git-wrapped).

Which breaks.

Closing, looks like a bunch of weird heisenissues that cleared up after talking on #reflex-frp
