pymsch

a package for generating mindustry schematic files with python code

here's a basic example:

from pymsch import Schematic, Block, Content

schem = Schematic()
schem.set_tag('name', 'Example Schematic')
schem.set_tag('description', 'A description for the schematic')

schem.add_block(Block(Content.COPPER_WALL, 0, 0, None, 0))

schem.write_clipboard()

This makes a schematic with a single copper wall, and outputs it to your clipboard to import into the game
