Is there no way to export the presets to a blueprint string ?

There are 2 blue buttons in the gui to export and import your configuration, to/from either a string or a blueprint (by holding shift)

I saw the blueprint option, but I was hoping for a method that I could import all my PRESET's in one go.

So I could share the configuration with others and import it into a new game.

Yeah, that was what i thought you wanted after hitting reply :D
Should be fairly simple to add, i just have to add the blueprints into a book i guess.

I am guessing that each players presets are stored in a table. You could convert the table to JSON then ENCODE it and give that to the player as a string to exchange.
local encoded_string = game.encode_string(game.table_to_json(preset_data_table))

To read the data back you would do this
local decoded_table = game.decode_string(game.json_to_table(imported_string_from_gui))

That would be probably the easiest way, but i'd like to have it as a book, so i can just drop it in the library instead of having to save it as a file somewhere.
I'll see what i can do in the next couple of days.

When the new blueprint update comes out this week, they have options to add text/comments which might help to implement this book design.

Hi ya .. are you still thinking / working on your blueprint book idea ?

I kinda forgot about it, sorry. I've added the functionality in the latest version.

I've got some presets saved as a blueprint, but I can't seem to import them into the mod in any way. I've clicked both import buttons and it gives a box to input a string. I try holding the blueprint and clicking the button but I get the same result. I try holding shift and clicking the buttons and again get the prompt to enter a string.... I can't really use this if it won't load my presets...

If you pick up the blueprint directly from the library it won't be recognized. That's a Factorio bug that will be fixed in 1.1
To workaround you have to put the blueprint in your inventory first and then import it.

Ah, good to know, thanks, I'll try that.
