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 ...
Lisp originally had very few control structures, but many more were added during the language's evolution. (Lisp's original conditional operator, cond, is the precursor to later if-then-else structures.) Programmers in the Scheme dialect often express loops using tail recursion. Scheme's commonality in academic computer science has led some ...
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.
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 ...
Practical Common Lisp is an introductory book on the programming language Common Lisp by Peter Seibel. [1] It features a fairly complete introduction to the language interspersed with practical example chapters, which show developing various pieces of software [2] [3] such as a unit testing framework, a library for parsing ID3 tags, a spam filter, and a SHOUTcast server.
The whitespace-separated notation used in Lisp (and this article) is typical. Line breaks (newline characters) usually qualify as separators. This is a simple context-free grammar for a tiny subset of English written as an S-expression (Gazdar/Melish, Natural Language Processing in Lisp), where S=sentence, NP=Noun Phrase, VP=Verb Phrase, V=Verb:
Richard P. Gabriel (born 1949) is an American computer scientist known for his work in computing related to the programming language Lisp, and especially Common Lisp.His best known work was a 1990 essay "Lisp: Good News, Bad News, How to Win Big", which introduced the phrase Worse is Better, [1] and his set of benchmarks for Lisp, termed Gabriel Benchmarks, published in 1985 as Performance and ...
For example, an object that is checked by a contract can be ensured to make contract checks when its methods are eventually invoked. Racket includes both bytecode and JIT (JIT) compilers. The bytecode compiler produces an internal bytecode format run by the Racket virtual machine , and the JIT compiler translates bytecode to machine code at ...
