Brian's Blueprints for Factorio
Don't just look at the latest release shown on the left. Each book is released separately so to see them you have to go to the all-releases page.
The "fbp.py" script can be used to split books into a directory structure and later build them back into a single entity as well as to unpack/pack single blueprints from their encoded form into json. The latter allows working with single blueprints within a book.
rm -rf book-directory
tools/fbp.py split --outdir=book-directory --infile=my-exported-book.txt
It's important to completely remove the old directory before splitting otherwise removed/renamed blueprints will remain in the previous form and be re-introduced when the book is next built.
tools/fbp.py build --outfile=my-book.txt --indir=book-directory
tools/fbp.py unpack --outfile=book-directory/blueprint.json --infile=my-exported-blueprint.txt
tools/fbp.py pack --outfile=my-blueprint.txt --infile=book-directory/blueprint.json
