Defined in:
lib/shadwire/commands/init.rb

Overview

Bootstraps a consuming Rails app: writes shadwire.json, installs the base files, and applies the base gems + the Tailwind @import (confirm-then-apply, auto on yes:). Idempotent on re-run; --force resets shadwire.json.

Constant Summary collapse

CLI_GEM =

The CLI gem is a development-time tool for the app, deliberately kept out of registry.json: the registry's gems are what the components need at runtime, and installed files carry no Shadwire dependency.

Binstub::GEM
CLI_GEM_GROUP = 
"development"
