mix mob.new (mob_new v0.3.0)

Creates a new Mob project with Android and iOS boilerplate.

mix mob.new APP_NAME [--liveview] [--python] [--ios | --android] [--no-install] [--dest DIR] [--local]

Platform selection

By default the generator emits boilerplate for both Android and iOS. Pass one of the platform flags to scope it to a single platform:

mix mob.new my_app --ios        # iOS only — no android/ directory generated
mix mob.new my_app --android    # Android only — no ios/ directory generated
mix mob.new my_app              # both (default)

--no-ios and --no-android are equivalent inverse forms (kept for back-compat). mix mob.install, mix mob.deploy, and mix mob.doctor detect the project's platform set from on-disk layout, so a single-platform project skips the absent platform's setup automatically.

Options

• --liveview — generate a Phoenix LiveView app wrapped in a Mob WebView.

                 Calls `mix phx.new` to scaffold a Phoenix project, then
                 adds the Mob native boilerplate and LiveView bridge patches
                 (MobHook in app.js, mob-bridge element in root.html.heex,
                 MobScreen, mob.exs with liveview_port). Requires
                 `phx_new` archive to be installed (`mix archive.install hex phx_new`).

• --ios — generate iOS boilerplate only (skip android/)

• --android — generate Android boilerplate only (skip ios/)

• --no-ios — alias for --android (skip iOS boilerplate)

• --no-android — alias for --ios (skip Android boilerplate)

• --python — pre-configure embedded CPython via Pythonx (iOS only).

                 Adds `:pythonx` to deps, generates a
                 `<App>.PythonPaths` detection module, and gates
                 `:pythonx, :uv_init` in `config.exs` on
                 `MOB_TARGET=ios`. Mirrors `mix mob.enable python`
                 post-scaffold. Bundle size ~70 MB; iOS only —
                 Android Python is intentionally out of scope. See
                 the `Embedded CPython` guide in mob_dev's docs.

• --no-install — skip running mix deps.get after generation

• --dest DIR — create project in DIR (default: current directory)

• --local — use path: deps pointing to local mob/mob_dev repos

                 instead of hex version constraints, AND render from
                 the local mob_new checkout's templates (not the
                 installed archive's, which can be stale relative to
                 master). **For Mob framework contributors only** —
                 not intended for app developers.
  
                 Mob paths resolved from `MOB_DIR` / `MOB_DEV_DIR`
                 env vars, falling back to `./mob` / `./mob_dev`,
                 then `../mob` / `../mob_dev`. mob_new template path
                 resolved from `MOB_NEW_DIR`, falling back to
                 `$HOME/code/mob_new`. Pre-fills `mob.exs` so
                 `mix mob.install` skips path configuration prompts.
  
                 If the local mob_new checkout can't be found, falls
                 back to the installed archive's templates and notes
                 it in the build output.

What gets generated (--liveview mode)

Everything mix phx.new APP_NAME --no-install generates, plus:

APP_NAME/
  lib/APP_NAME/mob_screen.ex      # Mob.Screen wrapping the Phoenix WebView
  mob.exs                          # Mob config with liveview_port: 4000
  android/                         # same Android boilerplate as native mode
  ios/                             # same iOS boilerplate as native mode

Patches applied to the Phoenix project:

• assets/js/app.js — MobHook definition + registration
• lib/APP_NAME_web/.../root.html.heex — mob-bridge hidden div
• lib/APP_NAME/application.ex — Mob.App child in supervision tree
• mix.exs — mob / mob_dev deps added

After generation, run:

cd APP_NAME
mix mob.install    # icon generation + any first-run setup
