The Scheme Programming Language
Scheme
Welcome to
Scheme.org
, a new home page for Scheme. We host a
snapshot
of the old Schemers.org. Thanks to
Prof. Shriram Krishnamurthi
and all the other people who gave Scheme a home on Schemers.org for nearly twenty-five years.
Scheme is a classic programming language in the
Lisp
family
. It emphasizes
functional
programming
and
domain-specific
languages
but adapts to other styles. Known for its clean and
minimalist design, Scheme is one of the longest-lived and
best-studied
dynamic
languages
, and has many fast and portable
implementations.
From the Scheme standard reports:
Programming languages should be designed not by piling feature
on top of feature, but by removing the weaknesses and
restrictions that make additional features appear necessary.
Scheme demonstrates that a very small number of rules for
forming expressions, with no restrictions on how they are
composed, suffice to form a practical and efficient programming
language that is flexible enough to support most of the major
programming paradigms in use today.
