AML - A Mathematical Language

AML is a small DSL written on top of GraalVM and its Truffle framework. Read the Specification for information about its features.

Modules

The language is structured in four modules:

• language: contains the language implementation and tests.
• polyglot: exemplifies how to use the DSL with Java.
• repl: a small REPL to try out the DSL.
• runner: provides an executable to run a AML file.

Development

The only required dependency is GraalVM version 21.0.0 which can be downloaded from the official GraalVM website. After downloading it and pointing the JAVA_HOME environment variable to it you are ready to go.

To build the project, a maven wrapper is available for both windows and unix systems. The following command compiles all code, executes the tests and builds all necessary JAR files:

# On windows use mwnw.cmd instead of mwnw
$ ./mwnw package

To actually use AML there are different possibilities:

• Using a REPL: the repl script provides the ability for both windows and unix to start a REPL and try out AML.
• Evaluating a source file: the runner script expects a file path as input and executes the file. Look at the samples of the repository for some example files.
• Embedding the DSL: to use the DSL as an embedded language through GraalVM a component has to be created first and installed using the Graal Updater tool. The make_component.sh, install_component.sh and remove_component.sh script show how this can be achieved. Furthermore the polyglot module, polyglot.rb and polyglot.clj show how AML can be embedded using different languages.
