  Bootstrapping a Forth interpreter from hand-written tiny ELF binary. Just for fun.

interpreter is designed to be very simple. Every built-in word is single-letter and the interpreter just repeats that reads a character, looks it up from the dictionary and executes it. Also there is no error checking.

This is the actual code for the first interpreter, which is a 136-byte implementation of the interpreter followed by a built-in dictionary of 888 bytes.

The first interpreter and language is so esoteric that, for example, the Hello World looks like this.

    $ ./planck
