sandwich

sandwich is a funny programming language written in Rust.

Running

Use cargo to run an input file.

git clone https://tildegit.org/karx/sandwich
cd sandwich
cargo run <filename>

Reference

sandwich is comprised of opcodes. The syntax looks like this:

opcodeArguments

The currently available opcodes are as follows:

• p - print out the arguments: pHello World! prints "Hello World!"
• a, s, m, d - add, subtract, multiply, and divide, respectively: a2-2 adds 2 + 2.
• l - declare a variable: lv9 declares variable v with value 9; doing p$v prints out 9.
• # - comment: the interpreter will skip this line.

Here's an example "Hello world" program:

lhHello
lwWorld!
p$h $w
