Arc (programming language)
Arc is a programming language, a dialect of the language Lisp, developed by Paul Graham and Robert Morris. It is free and open-source software released under the Artistic License 2.0.
In 2001, Paul Graham announced that he was working on a new dialect of Lisp named Arc. Over the years since, he has written several essays describing features or goals of the language, and some internal projects at Graham's startup business incubator named Y Combinator have been written in Arc, most notably the Hacker News web forum and news aggregator program. Arc was written in Racket. It has been rewritten using the Common Lisp implementation SBCL and called it is called Clarc.
In the essay Being Popular Graham describes a few of his goals for the language. While many of the goals are very general ("Arc should be hackable", "there should be good libraries"), he did give some specifics. For example, he believes it is important for a language to be terse:
It would not be far from the truth to say that a hacker about to write a program decides what language to use, at least subconsciously, based on the total number of characters he'll have to type. If this isn't precisely how hackers think, a language designer would do well to act as if it were.
He also stated that it is better for a language to only implement a small number of axioms, even when that means the language may not have features that large organizations want, such as object-orientation (OO). Further, Graham thinks that OO is not useful as its methods and patterns are just "good design", and he views the language features used to implement OO as partly mistaken. At Arc's introduction in 2008, Graham stated one of its benefits was its brevity.
A controversy among Lisp programmers is whether, and how much, the s-expressions of the language should be complemented by other forms of syntax. Graham thinks that added syntax should be used in situations where pure s-expressions would be overly verbose, saying, "I don't think we should be religiously opposed to introducing syntax into Lisp." Graham also thinks that efficiency problems should be solved by giving the programmer a good profiler.
When released in 2008, Arc generated mixed reactions, with some calling it simply an extension to Lisp or Scheme and not a programming language in its own right. Others applauded Arc for stripping Lisp down to bare essentials. Shortly after its release, Arc was ported to JavaScript, and was being supported by Schemescript, an integrated development environment (IDE) based on Eclipse.
