Intro

Dollar is a light-weight scripting language for the JVM. More specifically it is an integration centric, reactive dynamic programming language.

It is currently being built for the needs of server-side developers and Java developers in general who need to produce quick prototypes or write simple scripts. Furthermore it is an internet centric language where JSON and URIs are first class citizens.

The language is currently in early but active development.

I'm also working full-time on this, if you wish to support my efforts then please back me on Patreon:

And/or star the project on GitHub.

Thanks!

Example to find out your local air quality:

//First we get the Geo Location of our IP address
var geo= read http://freegeoip.net/json/
var lat= geo.latitude
var lon= geo.longitude

var quality= read ("https://api.openaq.org/v1/measurements?radius=10000&limit=5&coordinates="+ lat + "," + lon) as URI;

//Now output the quality from each result
quality.results each {
    @@ $1.location
    @@ $1.parameter +" was "+ $1.value +  " " + $1["unit"] +" on " + $1.date.utc
}

Docker

There is a docker image, but it is in it's infancy so better to work with the distribution for now.

docker run -v $HOME/.github:/root/.github -v $HOME/.dollar:/root/.dollar -v $(pwd):/build -it sillelien/dollarscript-headless:0.4  <filename>.ds
