# cat-disruptor-6500 A Discord bot that reacts to certain messages with certain emojis. More importantly, it also lets you write code! ## Commands: !START - start the interpreter !STOP - stop the interpreter LIST - list all code in memory SAVE filename - save code into database LOAD filename - load filename into memory DIR - list programs you have saved PUB filename - Publish a program PUBDIR - List published programs PUBLOAD id - Load public program by ID (IDs are listed in PUBDIR) Code is specified by writing `line_num code`. For example, `10 print "hello world"`. This makes it easy to insert new code or overwrite lines. ### Example session ``` !START 10 for x in 0 to 10 20 print x RUN > expected NEXT after FOR statement. # oops - we forgot a line 30 next x LIST > 10 for x in 0 to 10 > 20 print x > 30 next x RUN > 0 > 1 > 2 > 3 > 4 > 5 > 6 > 7 > 8 > 9 > 10 # actually, let's print them all on the same line 5 a = "" 20 a += x LIST > 5 a = "" > 10 for x in 0 to 10 > 20 a += x > 30 next x RUN 012345678910 # oops - let's add spaces 20 a += " " + x RUN > 0 1 2 3 4 5 6 7 8 9 10 # awesome! let's save this program SAVE count_to_ten > Saved as count_to_ten ``` The interpreter can execute arbitrary code safely - it includes CPU and memory limits.
