#Momoka

Create a minimal MoonBit module か?

Momoka is a single MoonBit module, kokic/momoka, with two packages:

Directory	Package	Target	Purpose
.	kokic/momoka	native, wasm	shared CLI
core	kokic/momoka/core	any	shared pure logic, no I/O

core holds the shared templates, settings resolution, and CLI definitions. The CLI shares argument parsing and project creation across both targets. Native builds read and save preferences in ~/.momoka/preferred.json; wasm builds use only command-line arguments and built-in defaults. Conditional compilation excludes preference file access and native-only commands from wasm builds.

moon run --target native . -- --help
moon run --target wasm . -- --help

#Example

# native: preferences are read from and saved to ~/.momoka/preferred.json
momoka new your-great-project

# or, cd <your-existing-project>
momoka init

# override project defaults for this invocation
momoka new your-great-project --username alice --license MIT --host gitlab.com --target js
momoka init --username alice

# configure or print the saved defaults
momoka cfg
momoka cfg --show

# upgrade all dependencies to their latest versions
momoka upgrade

# install the stable MoonBit toolchain
momoka stable

#WASM

The wasm build supports new and init only. It never reads or writes ~/.momoka; pass everything on the command line. --username falls back to guest when omitted.

moon run --target wasm . -- new your-great-project --username alice --license MIT

Run wasm builds with MoonBit's runtime (moon run / moonrun); the async library requires MoonBit host functions beyond standard WASI.

#Help

Usage: momoka <command>

Create a minimal MoonBit module.

Commands:
  new      Create a new MoonBit module in a new directory.
  init     Initialize a MoonBit module in an existing directory.
  upgrade  Upgrade all dependencies of the project to their latest versions.
  stable   Install the stable MoonBit toolchain.
  nightly  Install the nightly MoonBit toolchain.
  cfg      Configure default username / license / host / target, or print them.
  help     Print help for the subcommand(s).

Options:
  -h, --help     Show help information.
  -V, --version  Show version information.

The command list above is for native builds. Use momoka help <command> (or momoka <command> --help) for subcommand details. Both new and init support --username (-u), --license (-l), --host, and --target (-t). These options override the saved preferences for the current invocation without changing them. License, host, and target fall back to Apache-2.0, github.com, and native. Without --username or a saved username, Momoka prompts for one and saves it for future use. Use momoka cfg to configure default username, license, host, and target; press Enter to keep an existing value. Use momoka cfg --show to display all saved preferences.
