Bistro is a programming language designed and developed by Nikolas Boyd. It is intended to integrate features of Smalltalk and Java, running as a variant of Smalltalk that runs atop any Java virtual machine conforming to Sun Microsystems' Java specification.


Bistro is object oriented, dynamically typed, and reflective. It duplicates the vast majority of the syntax and API for Smalltalk, and introduces the package and import concepts from Java. Overloaded operators are available for certain operators; ++ and -- are not available overloaded operators.

The syntax for declaring a class's package and import clauses are:

package: my.package.subpackage;
import: my.package.MyClass;
import: my.package.*;

One notable exclusion is the ability to import static methods from other classes.


Nikolas S. Boyd created and released the first version of Bistro in 1999. There were no new developments with Bistro since 2010.[1]
