Default language of Nipp is Ruby because Ruby makes us comfortable to write program!
Nipp is highly powered by Opal, which is a transpiler to JavaScript. Thank you very much, Opal project!

Also JavaScript Not Only Ruby

Nipp is not only for Ruby. JavaScript is also available. Here is Tetris on Nipp!

Try on https://nipp.nwtgck.org/#Tetris/es2017/bU/bSuNQF... The Tetris program is from an Japanese article - Commentary of Only 565 Bytes Tetris Programming.

URL Structure

Here is a structure of Nipp URL.
nwtgck.github.io/nipp/#<Page Title>/<Options>/<Compressed Code>

• <Page Title> is title of your app
• <Options> can be es2017, lzma, es2017,lzma, lzma,es2017 or etc.
• <Compressed Code> is code compressed by deflate (no header, no checksum) or LZAM for now and encode it by Base64

Note that <Page Title>, <Options> and <Compressed Code> are under URL fragment #. This means your code is not send to Nipp web server!

Options

• es2017: Use ES2017 (default: Ruby(Opal))
• func_es2017: Use ES2017 but evaluated by (new Function(...))() not eval(), so output is always empty but faster
• lzma: Compress code by using LZMA (default: deflate)
• click_run: Click to run not real-time evaluation
• promise_wait: Wait for Promise evaluation in output

PWA - Progressive Web Apps

Nipp runs even offline! Note that Nipp is available in flight mode ✈️.
