Scheme (programming Language) - Usage

Usage

Scheme is widely used by a number of schools; in particular, a number of introductory Computer Science courses use Scheme in conjunction with the textbook Structure and Interpretation of Computer Programs (SICP). For the past 12 years, PLT has run the ProgramByDesign (formerly TeachScheme!) project, which has exposed close to 600 high school teachers and thousands of high school students to rudimentary Scheme programming. MIT's old introductory programming class 6.001 was taught in Scheme, Although 6.001 has been replaced by more modern courses, SICP continues to be taught at MIT. The textbook How to Design Programs by Matthias Felleisen, currently at Northeastern University, is used by some institutes of higher education for their introductory computer science courses. Both Northeastern University and Worcester Polytechnic Institute use Scheme exclusively for their introductory courses Fundamentals of Computer Science (CS2500) and Introduction to Program Design (CS1101), respectively. Indiana University's introductory class, C211, is taught entirely in Scheme. The introductory class at UC Berkeley, CS 61A, was until recently taught entirely in Scheme, save minor diversions into Logo to demonstrate dynamic scope; all course materials, including lecture webcasts, are available online free of charge. The introductory computer science courses at Yale and Grinnell College are also taught in Scheme. Several introductory Computer Science courses at Rice University are also taught in Scheme. Programming Design Paradigms, a mandatory course for the Computer science Graduate Students at Northeastern University, also extensively uses Scheme. The introduction Computer Science course at the University of Minnesota - Twin Cities, CSci 1901, also uses Scheme as its primary language, followed by a course that introduces students to the Java programming language. LambdaBeans is an open source Scheme editor, helping with syntax coloring, code completion, and other features typical to code editors. In the software industry, Tata Consultancy Services, Asia's largest software consultancy firm, uses Scheme in their month-long training program for fresh college graduates. Although there are relatively few examples of Scheme in apparent usage for non-pedagogical purposes, it is/was used for the following:

  • Monk, an implementation developed by SeeBeyond to support extending application functionality in their enterprise application integration tools.
  • The Document Style Semantics and Specification Language (DSSSL), which provides a method of specifying SGML stylesheets, uses a Scheme subset.
  • The well-known open source raster graphics editor GIMP uses Scheme as a scripting language.
  • Guile has been adopted by GNU project as its official scripting language, and that implementation of Scheme is embedded in such applications as GNU LilyPond and GnuCash as a scripting language for extensions. Likewise, Guile used to be the scripting language for the desktop environment GNOME, and GNOME still has a project that provides Guile bindings to its library stack.
  • Elk Scheme is used by Synopsys as a scripting language for its technology CAD (TCAD) tools.
  • Shiro Kawai, senior programmer on the movie Final Fantasy: The Spirits Within, used Scheme as a scripting language for managing the real-time rendering engine.
  • Google App Inventor for Android uses Scheme, where Kawa is used to compile the Scheme code down to byte-codes for the Java Virtual Machine running on Android devices.

Famous quotes containing the word usage:

    “...Often the accurate answer to a usage question begins, “It depends.” And what it depends on most often is where you are, who you are, who your listeners or readers are, and what your purpose in speaking or writing is.”
    —Kenneth G. Wilson (b. 1923)

    “Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
    —Fran Lebowitz (b. 1951)

    “I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
    —A.J. (Alfred Jules)
