Clamato is a Smalltalk dialect that is designed to operate within the JavaScript runtime.

Clamato is a Smalltalk dialect that is designed to operate within the JavaScript runtime. Clamato is self-hosting, in that it can compile itself to efficient JavaScript, entirely within the web browser. It uses a parser library based on Lukas Renggli’s PetitParser. Smalltalk constructs (eg: temps, instance variables, message sends, blocks) generally map one-to-one to their JavaScript equivalents (respectively: local variables, object properties, method calls, functions). There are several departures from Smalltalk’s syntax and semantics. The most notable of these are: no explicit returns, 0-based indexing, no metaclass hierarchy, special syntax for instance variables. Clamato includes an (incomplete) interface to the JQuery JavaScript library, along with a Seaside-like HTML builder. Cæsar is a system browser built on all of the above. Like Clamato, it departs in a few notable ways from traditional Smalltalk browsers, but retains their spirit.
