Hy is a dialect of the Lisp programming language designed to interact with Python by translating s-expressions into Python's abstract syntax tree (AST). [2] [3] Hy was introduced at Python Conference (PyCon) 2013 by Paul Tagliamonte. [4] Lisp allows operating on code as data (metaprogramming), thus Hy can be used to write domain-specific ...
CLPython is an implementation of the Python programming language written in Common Lisp. This project allow to call Lisp functions from Python and Python functions from Lisp. Licensed under LGPL. CLPython was started in 2006, but as of 2013, it was not actively developed and the mailing list was closed. [1]
Take for example, correction of an "S" sound (lisp). Most likely, a speech language pathologist (SLP) would employ exercises to work on "Sssssss." [clarify] Starting practice words would most likely consist of "S-initial" words such as "say, sun, soap, sip, sick, said, sail." According to this protocol, the SLP slowly increases the complexity ...
A Lisp list is written with its elements separated by whitespace, and surrounded by parentheses. For example, (1 2 foo) is a list whose elements are the three atoms 1, 2, and foo. These values are implicitly typed: they are respectively two integers and a Lisp-specific data type called a "symbol", and do not have to be declared as such.
The programming language Lisp is the second-oldest high-level programming language with direct descendants and closely related dialects still in widespread use today. The language Fortran is older by one year. [1] [2] Lisp, like Fortran, has changed a lot since its early days, and many dialects have existed over its history.
Self-organizing list, a strategy for re-ordering the keys in an association list to speed up searches for frequently-accessed keys. Property list, or plist, another associative array data structure used in Lisp [11] (not to be confused with property lists, a file format also called plist files).
Examples include: 1) joining LISP sites connected to "disjointed locator spaces"—for example a LISP site with IPv4-only RLOC connectivity and a LISP site with IPv6-only RLOC connectivity; and 2) creating a data plane 'anchor point' by a LISP-speaking device behind a NAT box to send and receive traffic through the NAT device. [9]
In the usual parenthesized syntax of Lisp, an S-expression is classically defined [1] as an atom of the form x, or; an expression of the form (x. y) where x and y are S-expressions. This definition reflects LISP's representation of a list as a series of "cells", each one an ordered pair. In plain lists, y points to the next cell (if any), thus ...
