# Silver

Silver is an extensible attribute grammar system that support many

modern extensions to Knuth's original design.  These include

higher-order attributes, reference attributes, forwarding, aspects,

and collections attributes.  Its type system support parametric

polymorphism.  Silver is distributed with Copper, a parser and

context-aware scanner generator.

It is designed for the modular development of composable language

extensions, with language features and analyses to support this.

## Using silver

Silver requires Java 11, Ant 1.10.0, Bash, and wget. It can run on Linux, MacOS, and Windows Subsystem for Linux (WSL) in Windows 10.

See [The Silver Install Guide](http://melt.cs.umn.edu/silver/install-guide)

for detailed information on how to get Silver set up.

Silver is written in Silver, which means after cloning the GitHub

repository you still need the executable Java jar files. You can download

these by running the ``update`` script in this repository. This will do a

`git pull` to update, then download jars, and clear any files generated

by older versions of Silver. A one-stop-shop for updating after the

initial clone.
