uncompressed blueprint string

[ichVII]

In addition to the import_stack and export_stack features, I would like to have an option to use similiar features with the uncompressed blueprint string. While set/get_blueprint_entities/tiles/entity_tags are great, it would be nice to have one combined access to all information.

I tried to inflate a string in lua, but I only found ways, that require specific libraries, which I propably cant or shouldnt include in a mod.

Alternatively adding game.inflate and game.deflate to inflate/deflate strings would solve my problem as well.

I am trying to change the colour of a coloured blueprint and if i could get access to the uncompressed blueprint string, it would be as easy as replacing the name of the blueprint in the uncompressed string. (at the end in item: …).

+1 for zip/deflate support

Would be handy to generate custom "exchange strings" too (for modded stuff other than blueprints).

As a workaround, you can include the zip library yourself. https://github.com/DaveMcW/blueprint-st ... rintstring

+1. Having inflate / deflate and base64 encode/decode available to be used anywhere, not just for blueprints, would be amazing.

Isn't base64 en- and decode already available in the core lualib util file?

[raiguard]

Well yes, but not zlib inflate and deflate.

Had to search a bit until i found what you mean so i'll post it here for future readers:

Code: Select all

LuaGameScript.encode_string(string) → string	Deflates and base64 encodes the given string.
LuaGameScript.decode_string(string) → string	Base64 decodes and inflates the given string.

As far as i know "blueprint exchange string" has some factorio specific decorations (version byte?). So i'm wondering if that needs to be manually handled?

[raiguard]

Yes, the Factorio blueprint strings have a single digit at the beginning denoting a version. Remove the first character of a compressed blueprint string and it'll work with the new functions.
