Agora is a dynamically typed, garbage collected, embeddable programming language. It is built with the Go programming language, and is meant to provide a syntactically similar, loose and dynamic companion to the statically typed, machine compiled Go language - somewhat like Lua is to C.

go get -t github.com/PuerkitoBio/agora/...

This will install the agora packages as well as the agora command-line tool. See agora -h for help, provided the $GOPATH/bin path is in your exported path. The -t flag installs the test dependencies, it works only on Go tip (latest development version), ignore it otherwise.

More examples are available in the wiki and the source code under /testdata/src, but to give a taste of the syntax, here is the usual hello world:

// Output: Hello, Agora !
fmt := import("fmt")
func greet(name) {
	fmt.Println("Hello,", name, "!")
}
greet("Agora")

A few things to note:

• It looks very similar to Go, minus the types.
• import is a built-in function, not a keyword. This is important with dynamically-loaded modules, it gives you control of where this overhead of loading and compiling the code is done. It returns the value exported by the module - in this case, an object that exposes methods like Println.
• Obviously, since this is a dynamically-typed language, arguments have no types.
• := introduces a new variable. Using an undefined variable is an error, so this statement could not have been =.
• Statements are valid in the top-level (module) scope. That's because a module (the name for an agora file) is an implicit (top-level) function.
• Semicolons are managed just like in Go, so although they are inserted in the scanning stage, they are optional (and usually omitted) in the source code.
