Usage

The compiler is still a work-in-progress, and is not yet functional. Once it is functional, however, it can be invoked using:

rygg vmu compile example.rg -output example.vms

To assemble a file, use the rygg vmu assemble command:

rygg vmu assemble example.s -output example.vms

For help, run rygg help:

% rygg help
Compiler and build tool for Dreamcast VMU

  rygg SUBCOMMAND

=== subcommands ===

  vmu      Operations for Dreamcast VMU
  version  print version information
  help     explain a given subcommand (perhaps recursively)

The help command can be used on subcommands as well:

% rygg help vmu
Operations for Dreamcast VMU

  rygg vmu SUBCOMMAND

=== subcommands ===

  assemble  Assembler for Dreamcast VMU
  compile   Compiler for the Rygg programming language
  help      explain a given subcommand (perhaps recursively)

---

% rygg vmu help assemble
Assembler for Dreamcast VMU

  rygg vmu assemble INPUT-FILE

=== flags ===

  -output  output-file
           (alias: -o)
  [-help]  print this help text and exit
           (alias: -?)

Build

Requires opam 2.0.

When trying to build for the first time, you may want to create a local switch. To do so, cd into the source directory, and run:

opam switch create . --empty

Install dependencies:

opam install . --deps-only --unlock-base --locked -y

To build using dune directly, run

dune build @all

To build with all warnings as errors:

dune build @all --profile check

To build a statically-linked executable (doesn't work on macOS):

dune build @all --profile static

Lockfile

To re-generate the lockfile, run opam lock ..

Unit Tests

To run the unit tests, use

dune runtest

utop

Ensure utop is installed:

opam install utop

Start utop with the sources from the current project:

dune utop src
