Amoeba Interpreter

An interpreter for the Amoeba programming language. Written from scratch in Go with no dependencies 🎉

Features

• C-like syntax
• variables (integers, booleans, strings, arrays, objects)
• arithmetic expressions
• first-class and higher-order functions
• closures
• builtin functions:
  • amoeba(): prints out awesome ascii art
  • len(ARRAY or STRING): returns length of string or array
  • push(ARRAY, ANY): adds new item to array (does not mutate)
  • first(ARRAY): returns first item in array
  • rest(ARRAY): returns all but first item in array
  • last(ARRAY): returns last item in array
  • print(ANY, ANY, ...): prints out to the console

Give it a try!

Clone

1. git clone https://github.com/ASteinheiser/amoeba-interpreter.git
2. cd amoeba-interpreter

Then pass a file path as an argument

./amoeba-interpreter -file=amoeba-test-program.txt

OR use the REPL

./amoeba-interpreter

Local Dev

1. Install Go
2. git clone https://github.com/ASteinheiser/amoeba-interpreter.git
3. cd amoeba-interpreter
4. go run main.go

Run the test suite

You can run the tests for a sub-module individually as long as it has a *_test.go file:

go test ./ast/
go test ./lexer/
go test ./parser/
go test ./evaluator/

OR you can run all the tests at once:

./run-tests.sh

Roadmap

• add <= and >= operators
• add postfix operators (such as ++)
• prettier printing of function, array, and hash values
• enhance error messages with line number and file name
