LackeyBot packSlots code
This contains the code that LackeyBot runs for customized pack collation (packSlots) for its internal use and for generating Planesculptors pack files.
packgen.js generates packSlots code from user input strings, for example
9x Common
3x Uncommon
1x Rare
1x DFC
1x Foil
It also supports building fully custom slots by defining Scryfall-style filters to define what can roll and the chances to do so. For example, you could define an alternate rare-mythic slot that's mythic twice as often with this string:
1x filters: "r=m","r=r" chances: 0.27,0.73
collator.js generates arrays of card names (packs) from packSlots
library-example.js builds the magic library that is used.
fuzzy.js contains searching functions, allowing slots to be filtered by Scryfall filters
toolbox.js contains general scripts
This can be used for other programs, but will need either to be modified to support their system, or will need a translate function to LackeyBot's database. A translate function for mtgjson -> LackeyBot internal already exists.
