A scryfall image downloader I made to practice working with LuaSec, web apis, and Lua's coroutines. Not really meant for actual use, but could be convenient for something.
Needs LuaSec and the cjson libraries, which are on luarocks
$ luarocks install luasec
$ luarocks install lua-cjson
Should be compatible with Lua 5.1-5.3 and LuaJIT. To use just run it from a command line with search terms as arguments
$ lua scryfallImageDownload.lua "once upon a time" "sliver queen"
Or make the file executable
$ chmod +x scryfallImageDownload.lua
$ ./scryfallImageDownload.lua "gilded goose" "gideon blackblade" "food chain"
