otherfunc-forth

Forth interpreter with compilation mode, 64 built-in primitives, and HTTP/KV outbound support.

Implementation

• i64 cells, 65,536-cell memory, 1,024-depth stack limit
• Compilation mode (: word ... ;) compiles to token sequences, interpreted mode for immediate execution
• 64 built-in primitives: stack ops, arithmetic, comparison, logic, I/O, control flow, loops, memory, variables/constants, strings, HTTP, KV
• Loop constructs: do...loop, +loop, begin...until, begin...while...repeat, begin...again
• HTTP outbound via coroutine/yield: s" url" http-get, s" url" s" body" http-post, s" KEY" env
• KV storage via coroutine/yield: s" key" kv-get, s" key" s" value" kv-set, s" key" kv-del
• Default instruction limit: 10,000,000 (configurable via with_instruction_limit())

Install

cargo install --path .

Usage

# Inline code
forth "3 4 + ."

# From file
forth -f program.fth

# Piped input
echo "hello" | forth "begin key dup while emit repeat"

As a Library

use otherfunc_forth::ForthInterpreter;
use otherfunc_core::Interpreter;

let mut forth = ForthInterpreter::new();
let output = forth.execute("3 4 + .", "").unwrap();
assert_eq!(output, "7 ");
