fix for after glr

[spebern]

Hi,

I found your module last week and it is awesome! It's a pitty that it seemed to have stopped working after glr. I tried to fix it, but I stumbled from on error to the next and finally started from scratch. However I kept your great layout and ideas (which saved me lots of lots of time).

If you have time you might want to take a look at my fork and tell me if this is something that you would pull, or tell me if there is anything that you would like to be changed first.

I didn't keep the syntax format because my editor made it quite difficult for me to keep it and I admit that I was too lazy to make changes in that area. If this is something that concerns you I could also change it.

Thanks for starting this project!

All the best, Bernhard
