lolbison

A LOLCODE interpreter written in C++ using Flex and Bison

Building & running lolbison

$ mkdir build
$ cd build
$ cmake ..
$ make
$ ./lolbison {{path/to/file.lol}}

Use flag -p to output the abstract syntax tree instead of interpreting.

Implemented functionality

• Types: NUMBR (int), YARN (string), TROOF (bool) and NOOB (nil)
• Binary math operators
• Boolean operators
• if-then-else statement (without MEBBE)
• Loops
• VISIBLE (print to stdout)
• SMOOSH (string concatenation)
• ENUF (as break in a loop, as exit outside loops)
• Arrays (reduced functionality)

The difference from lolcode specification v1.2

• There is only one variable scope
• A variable can be declared multiple times. Just like a function in C++
• Arrays work like dictionaries with integer keys
