Well finally I created my own package to convert my screenplays in a industry standard format is called afterwriting and I first installed it the nodejs via, but it was a pain in the ass to update and that things. So a few days ago a read the ArchWiki and started to make my own package, is working fine on my system.
Now I’m reading the part to upload it to the AUR, but I don’t know if someone will think is useful.
Also is someone wants to check the package to see it works in other computers just let me know (and I send the PKGBUILD, I think with that is all you need to check)
EDIT: Sorry I just make the package the program is the well known Afterwriting that processes .fountain files to screenplay pdf format.
