if [[ -a "$APPNAME.app" ]]; then
  echo "App already exists :'(" >&2
  echo "$PWD/$APPNAME.app"
  exit 1
fi

mkdir -p "$APPNAME.app/Contents/MacOS"
touch    "$APPNAME.app/Contents/MacOS/$APPNAME"
chmod +x "$APPNAME.app/Contents/MacOS/$APPNAME"

DONE=false
until $DONE ;do
  read || DONE=true
  echo "$REPLY" >> "$APPNAME.app/Contents/MacOS/$APPNAME"
done

echo "$PWD/$APPNAME.app"

appify v2.0.1 assumes my-script.sh has a newline at the end of the file. If not, it will chop off the last line, effectively breaking the generated app. I’ve fixed this in my fork of this gist, by replacing the while read loop with this:

DONE=false
until $DONE ;do
  read || DONE=true
  echo "$REPLY" >> "$APPNAME.app/Contents/MacOS/$APPNAME"
done

Updated to your 2.0.2!
Thanks Mathias!

You could also add [[ ! $REPLY ]] && continue after line 25, which will cause all redundant newlines to be skipped. (See my fork.)

Maybe it should just cp the file in there instead and avoid all these silly issues.

Hey @subtleGradient, I just rewrote appify so it uses cp which avoids a lot of problems. Check it out: https://gist.github.com/674099

It wouldn't work on OS X 10.10 until I added $APPNAME.app/Contents/Info.plist containing at least <plist><dict></dict></plist>

I created an app, but it won't execute when I double-click on the bundle. It is just a #!/bin/sh script that has a echo "hello world" statement in it for testing purposes. Can someone give me some guidance on how to get my app to run from clicking on the bundle? Appify did not create a Info.plist file for me, maybe this is the issue? What needs to be in that file? Thanks!

I forked this and added option-parsing, overridable icons file, and some other bits: https://gist.github.com/oubiwann/453744744da1141ccc542ff75b47e0cf
