Dune switch [do not merge]

[UnixJunkie]

If we do this, then it compiles with dune, but all the tests and examples fail like

File "/home/berenger/src/ocamlscript/tests/./unpack", line 9, characters 0-26:
Error: Unbound module Ocamlscript

Hence the [do not merge].

[UnixJunkie]

related to #7

[jrfondren]

the errors are due to META getting installed as an empty file. dune installs the file, but only the Makefile populates it

[jrfondren]

fix: rename META.in to META.ocamlscript.template

since a version's not set anywhere, dune will generate one like v2.0.3-46-gbc58ce8-dirty, but it works.

[UnixJunkie]

you should ask to become the maintainer of this project to @mjambon

My commitment to OCaml isn't firm right now, so that's probably a bad idea. What I'd prefer is also a break from the current design:

1. dune for script configuration instead of Ocaml.packs et al., with camlp4 or ppx and such offloaded to dune in an ephemeral project
2. configuration in a comment so that ocamlscript tolerates it

#! /usr/bin/env ocamlscript

(* (executable (libraries unix)) *)

let () =
  let file = Sys.argv.(1) in
  try
    Unix.access file [Unix.R_OK];
    print_endline ("file exists: " ^ file)
  with Unix.Unix_error (Unix.ENOENT, _, _) ->
    print_endline ("file doesn't exist: " ^ file)

@UnixJunkie got any feedback on https://github.com/jrfondren/thin-ocamlscript ?

This loses calc.ml, and the result is

#! /usr/bin/env -S thin-ocamlscript -package unix -linkpkg --

let () =
  if Array.length Sys.argv <> 2 then (
    Printf.printf "usage: %s <file>\n" Sys.argv.(0);
    exit 1);
  let file = Sys.argv.(1) in
  try
    Unix.access file [Unix.R_OK];
    print_endline ("file exists: " ^ file)
  with Unix.Unix_error (Unix.ENOENT, _, _) ->
    print_endline ("file doesn't exist: " ^ file)
