Joule (programming language)
Summary
Joule is a capability-secure massively-concurrent dataflow programming language, designed for building distributed applications. It is so concurrent that the order of statements within a block is irrelevant to the operation of the block. Statements are executed whenever possible, based on their inputs. Everything in Joule happens by sending messages. There is no control flow. Instead, the programmer describes the flow of data, making it a dataflow programming language.
Joule development started in 1994 at Agorics in Palo Alto, California. It is considered the precursor to the E programming language.
Numerals consist of ASCII digits 0–9; identifiers are Unicode sequences of digits, letters, and operator characters that begin with a letter. It is also possible to form identifiers by using Unicode sequences (including whitespace) enclosed by either straight (' ') or standard (‘ ’) single quotes, where the backslash is the escape character. Keywords have to start with a letter, except the • keyword to send information. Operators consist of Unicode sequences of digits, letters, and operator characters, beginning with an operator character. Labels are identifiers followed by a colon (':').
At the root, Joule is an imperative language and because of that a statement-based language. It has a rich expression syntax, which transforms easily to its relational syntax underneath. Complex expressions become separate statements, where the site of the original expression is replaced by a reference to the acceptor of the results channel. Therefore, nested expressions still compute completely concurrently with their embedding statement.
