gem "svelte-ruby", "~>0.1"
```

## Development

### Svelte Source

https://svelte.technology

The svelte-ruby gem ships with a working svelte source: `lib/svelte.js`. No need to regenerate it except for development or configuration.

The rollup task transpiles the svelte source to a format that's compatible with Execjs. The result is written to `lib/svelte.js` with these commands: `cd svelte && rollup -c rollup/rollup.config.ruby.js`

Copy config to svelte repo

```
rake svelte:copy_config
```

Transpile to Execjs compatible

```
rake svelte:rollup
```

### Dev Requirements

* [hoe](https://github.com/seattlerb/hoe) gem manager
* [hoe-bundler] may need `gem install hoe-bundler` installation before using `rake bundler:gemfile`
* [YARD](http://yardoc.org) docs
* [redcarpet](https://github.com/vmg/redcarpet) for yardoc
* [npm rollup] is needed locally to regenerate the svelte source for Execjs
