A "Hello world" example for the `affix-grammar` sentence generator.

-- # Welcome to Affix Grammar!
-- Affix Grammar is a tool which lets you write grammars, and randomly generates sentences based on those grammars.
-- You can use it to:
-- - generate stories (kinda like Mad Libs),
-- - test out context-free grammars,
-- - test your knowledge of the grammar of a human language you're learning!

-- Here's a simple grammar which generates "hello world" sentences from different languages.
-- 
-- Click the `Generate` button a few times to see the sentences that are produced!
-- 
-- You can edit this grammar by clicking on the `Edit` tab.

rule start = hello_world.Language "(" + @Language + ")"

rule hello_world.Language =
    .english -> "Hello, World!"
    .spanish -> "¡Hola Mundo!"
    .japanese -> "こんにちは世界！"
    .arabic -> "مرحبا بالعالم!"
    .indonesian -> "Salamu, Dunia!"
    .uyghur -> "ياخشىمۇسىز دۇنيا!"
    .greek -> "Γειά σου Κόσμε!"
    .ukrainian -> "Привіт Світ!"
    .thai -> "สวัสดีชาวโลก!"
    .french -> "Bonjour le monde!"

-- # About the Project
-- Affix Grammar (name subject to change) was heavily inspired by [Dr. Kate Compton](https://github.com/galaxykate)'s [Tracery Project](https://github.com/galaxykate/tracery), and incorporates additional ideas from the paper [Affix Grammars for Natural Languages](http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.53.5264&rep=rep1&type=pdf) about [Affix Grammars](https://en.m.wikipedia.org/wiki/Affix_grammar).

-- ## Technical Details
-- The Affix Grammar parsing and generation engine is written in the [Rust](https://rust-lang.org) language and compiled to [Webassembly](https://webassembly.org/). Markdown rendering is done by a Rust library called [pulldown-cmark](https://crates.io/crates/pulldown-cmark). This frontend is written in [Vue.js](https://vuejs.org/), and the text editor is [Ace](https://ace.c9.io/).
