factorio-blueprint-decoder VS factorio-draftsman

Factorio Blueprint Decoder Some pieces of this may need to be modified depending on your environment. For example: The Windows 10 & Git Bash example, in the image, required modifications: Two additional executables needed to be added to the environment, and modifications to factorio-blueprint-decoder/decode-export-string and encode-export-string were required [i].

This might be a solid jumping off point for you if you really want to go for it. https://github.com/asheiduk/factorio-blueprint-decoder

I made a library in Python called factorio-draftsman that works with blueprint strings which is pretty much entirely up to date and has all the data encoded in it, though quite not in a user-friendly JSON dump. I did end up manually making type-hinted dumps for all the Blueprintable types (Blueprint, BlueprintBook, UpgradePlanner, DeconstructionPlanner) though; so if that's sufficient you should be able to reliably use those. If you're looking for entity-specific schemas though, I haven't got around to doing all of them yet. Most of them are pretty straightforward however; position, orientation, filters, etc. The only complications you get into are stuff like control_behavior which has many different unique keys for many different entity types (you can take a look at the signatures.py file in draftsman's source for an impression). I can go more into that if you want, but I agree that this should really be documented/updated.

Finally, once the layout is generated, a blueprint string is created using u/redruin0001's Factorio Draftsman program. If you missed the Alt-F4 about this back in May 2022, I highly recommend checking it out. Factorio Draftsman is an extremely powerful tool for programmatically generating blueprint strings. In this instance, it is used to stitch together tens to hundreds of factory block blueprints together into a single one. This final blueprint can then be imported and placed in Factorio.

This was something I made on a whim. It uses the Pillow image library to load an image, and converts it to a blueprint intended to be visible from the map view, all in less than 150 lines of code:
