Kemalyst command line tool for console, init, generate (scaffolding), and watch.

kemalyst-generator

Rails like command line for kemalyst

Installation

You can build the kgen tool from source:

$ git clone git@github.com:kemalyst/kemalyst-generator.git
$ cd kemalyst-generator/
$ shards install
$ make

You should now have a bin/kgen file to run.

You can symlink this to a more global location like /usr/local/bin to make it easier to use:

$ ln -sf $(pwd)/bin/kgen /usr/local/bin/kgen

Optionally, you can use homebrew to install.

$ brew tap kemalyst/kgen
$ brew install kgen

Usage

kgen init app [your_app] -d [pg | mysql | sqlite] -t [slang | ecr] --deps 
cd [your_app]

options: -d defaults to pg. -t defaults to slang. --deps will run crystal deps for you.

This will generate a traditional web application:

• /config - Application and HTTP::Handler config's goes here. The database.yml and routes.cr are here.
• /lib - shards are installed here.
• /public - Default location for html/css/js files. The static handler points to this directory.
• /spec - all the crystal specs go here.
• /src - all the source code goes here.

Generate scaffolding for a resource:

kgen generate scaffold Post name:string body:text draft:bool

This will generate scaffolding for a Post:

• src/controllers/post_controller.cr
• src/models/post.cr
• src/views/post/*
• db/migrations/[datetimestamp]_create_post.sql
• spec/controllers/post_controller_spec.cr
• spec/models/post_spec.cr
• appends route to config/routes.cr
• appends navigation to src/layouts/_nav.slang

Run Locally

To test the demo app locally:

1. Create a new Postgres or Mysql database called [your_app]_development
2. Configure your database with one of the following ways.
   • Add it in config/database.yml
   • Run export DATABASE_URL=postgres://[username]:[password]@localhost:5432/[your_app]_development which overrides the config/database.yml.
3. Migrate the database: kgen migrate up. You should see output like Migrating db, current version: 0, target: [datetimestamp] OK [datetimestamp]_create_shop.sql
4. Run the specs: crystal spec
5. Start your app: kgen watch
6. Then visit http://0.0.0.0:3000/

Note: The kgen watch command uses Sentry to watch for any changes in your source files, recompiling automatically.

If you don't want to use Sentry, you can compile and run manually:

1. Build the app crystal build --release src/[your_app].cr
2. Run with ./[your_app]
3. Visit http://0.0.0.0:3000/
