_hex_ is a concatenative programming language heavily inspired by [min](/min) and [mn](/mn), but even more minimalist. 

It is implemented in a single C file, and provides:

- support for 32bit integers, but written only in hexadecimal format (hence the name), strings, quotations (lists) and symbols.
- the possibility to define your own symbols, but they will always be global (no lexical scoping).
- an interactive REPL.
- an integrated manual/cheat sheet.
- basic error handling and a stack trace
- 64 native symbols to manage control flow, arithmetical operations, comparison, Boolean logic, operations on strings and quotations, bitwise operations, I/O, File I/O, and shell command execution.

Despite its quirks, _hex_ aims to bring more people into the world of concatenative programming. The language web site includes a short tutorial, a simple specification of the language, and even a WASM-powered playground with an actual hex REPL to play with.
