`prc`, a compiler for the Prose programming language

IMPORTANT NOTE: Prose is still under heavy development. It is therefore not ready for production yet.

Prose is a new and small programming language that aims for readability and native interoperability with C. Its syntax, while a bit distant from ALGOL-like languages like C, should still be readable to most programmers.

Most remarkably, Prose avoids sigils such as {}, $ or any other kind of symbol, in favour of simple and readable English-like statements. The only exception is *, which is used for comments:

A hello world example:

* this is a comment
public function main
linkage
    status word
procedure returning status
    display "hello world"
    set status to 0

As opposed to other programming languages such as Python, Prose follows free-form syntax, and therefore the same program can be written in any format:

public function main linkage status word procedure returning status display "hello world" set status to 0

Prose follows the C ABI and also inherits its type system:

public function main
imports "cstd"
linkage
    status cint
    argc cint
    argv pointer to array of etc byte
storage
    fd cint
procedure using argc argv returning status
    display "argc=" argc ", argv=" argv
    call socket using AF_INET SOCK_STREAM 0 returning fd
    display "fd=" fd
    call close using fd
    set status to 0
