Is there any chance of getting
hooked up to the PacletManager?
I'd like to auto-include my own formats via Paclet. I'm picturing it working via a "Formats" argument in the "Extensions"
I think it'd be useful for the developers I know
What exactly do you want to achieve?
It is possible to register a new format in a paclet code. Here is an example: https://github.com/WolframResearch/BioFormatsLink
I want auto-linking, like the internal formats work. If I drop my format into $InstallationDirectory/SystemFiles/Formats it will be found automatically by the system.
It didn't seem there was a way to get that to work with the PacletManager for custom paclets from looking through the source code.
