A Go interpreter and compiler for the Monkey esolang.
Monkey has a C-like syntax, supports variable bindings, prefix and infix operators, has first-class and higher-order functions, can handle closures with ease and has integers, booleans, arrays and hashes built-in. The language was created for Thorsten Ball's Writing An Interpreter In Go and Writing A Compiler In Go texts.
Support is provided for executing source files as well as launching the REPL:
go run main.gowill open the REPLgo run main.go ./hello_world.mnkwill execute the specified source file
By default, execution is done using the VM created from the compiler book. The --no-vm flag can be used to instead execute using the interpreter created from the interpreter book.
- Macro support from The Lost Chapter: A Macro System For Monkey is implemented
