mix mob.install (mob_dev v0.3.37)

Copy Markdown View Source

Runs first-time setup for a Mob project generated by mix mob.new.

Must be run from inside the project directory (the one containing mix.exs).

mix mob.install [--icon PATH]

What it does

  1. Prompts for machine-specific paths (mob_dir, elixir_lib) and writes them to mob.exs (gitignored) and android/local.properties
  2. Downloads and caches the pre-built OTP runtime tarballs for Android and iOS
  3. Writes the Mob logo as a placeholder app icon (if no icon exists yet)

Options

  • --icon PATH — use a custom image instead of the Mob logo placeholder

Icon output

  • android/app/src/main/res/mipmap-*/ic_launcher.png
  • ios/Assets.xcassets/AppIcon.appiconset/icon_*.png + Contents.json

The Mob logo is written as a placeholder. Replace it any time:

mix mob.icon                     # generate a custom icon
mix mob.icon --source my_logo.png

Under the hood

mix mob.install does three things that would otherwise require manual steps:

1. Path configuration — reads mob.exs, detects sensible defaults, prompts for missing values, and writes them back. Equivalent to:

# mob.exs (gitignored, machine-specific)
config :mob_dev,
  mob_dir: "/Users/me/code/mob"

2. OTP download — fetches pre-built ERTS tarballs from GitHub Releases:

# Roughly equivalent to:
curl -L https://github.com/genericjam/mob/releases/download/<tag>/otp-android-arm64.tar.gz          -o ~/.mob_dev/otp-android-arm64.tar.gz

3. Placeholder icon — writes the Mob logo to all platform icon sizes (pre-built PNGs, no system tools required). Run mix mob.icon afterwards to replace it with a custom icon.
