Hi all.

Is there any reference on the fields inside info.json ?

In particular, I want to know the exact restrictions on "name" (permitted characters, length etc.) and "version" (max values, are the 3 "a.b.c" sections mandatory?)

Cheers

I don't know any (official) documentation, but from experience:

"Version" must have three numbers, seperated by dots. I haven't ever seen a mod use something higher than 20-ish for any of them, so if you want to use three digits you'll have to try yourself.

"Name" is a string made from numbers and digits. Spaces are now disallowed (edit: on the mod-portal only) though some legacy mods are still allowed to use their original name. As a convention most mods use a dash '-' instead of space where applicable, because underscore '_' is already used to seperate name from version. Special characters... are probably disallowed. I'm not aware of any length restriction.

But instead of asking here it's far faster to just test yourself :p.

Spaces work just fine in the game (as does any other character that your filesystem allows). The only place they aren't accepted is the mod portal and only because the guys who wrote it don't like spaces (they work perfectly fine with the legacy mods that do use spaces on the mod portal).

Thanks, i edited the original post to be more clear (i assumed that the OP would want to naturally put their mod on the portal eventually). How does the mod portal handle the "any other character that your filesystem allows" part?

Thanks all.

The requirement is actually for an external data-mining app... I want to extract icons from mods and need to convert (for example) __BeastFinder__/graphics/xyz.png"
to
"BeastFinder_0.16.1/graphics/xyz.png" or "BeastFinder_0.16.1.zip/graphics/xyz.png" as appropriate.
