Editing Live coding (section)

=== Representation and manipulation of time ===
The specific affordances of time-based media and live interaction with code has led to a number of novel developments and uses in programming language design. Through mutual embedding of imperative and declarative subsystems, the programming language [[SuperCollider]]<ref>James McCartney (1996), SuperCollider: a new real time synthesis language, ICMC Proceedings, 1996.
</ref> permitted to build a library that allows incomplete and provisional specifications which can be rewritten at runtime.<ref>Julian Rohrhuber, Alberto de Campo, and Renate Wieser (2005), Algorithms today - Notes on Language Design for Just In Time Programming, Proceedings of International Computer Music Conference (Barcelona), ICMC, 2005, pp. 455–458.</ref>

The [[ChucK]] language introduced an approach to "strongly timed" programming in 2002, embedding precision timing into control flow through a concise syntax.

"Temporal recursion" was a term initially coined in relation to the [[Impromptu (programming environment)|Impromptu]] programming environment. Technical elements within a programming environment continue to locate compressors and recursion solutions, but timing had been a major issue. While the general form of a temporal recursion, being any asynchronous function recursion through time, is available to any event driven system, Impromptu has placed a special emphasis on this particular design pattern,<ref>Sorensen, A & Gardner, H (2010) "[http://eprints.qut.edu.au/55712/1/sorensen_ow_2010.pdf Programming With Time: Cyberphysical Programming In Impromptu, In proceedings of the ACM Splash Conference 2010]"</ref> making it the centre piece of the concurrency architecture on that platform. Temporal recursion had repeatedly been used in [[SuperCollider]] and has since been implemented in the [[Fluxus (programming environment)|Fluxus]] environment.

Another functional approach to the representation of time is shown in the [[Tidal (livecoding)|Tidal]] pattern [[Domain-specific language|DSL]],<ref>{{cite book|last=McLean|first=Alex|chapter=Making programming languages to dance to: Live Coding with Tidal|url=https://github.com/yaxu/Tidal/blob/master/doc/farm/farm.pdf?raw=true|title=In proceedings of the 2nd ACM SIGPLAN International Workshop on Functional Art, Music, Modelling and Design|year=2014|location=Gothenburg}}</ref> which represents patterns as combinators operating over functions of time, similar to techniques in [[functional reactive programming]].<ref>{{cite web|last=McLean|first=Alex|title=Tidal homepage|work=Alex McLean |url=https://yaxu.org/tidal/|date=2013-08-02}}</ref>
