In the programming language Lisp, the reader or read function is the parser which converts the textual form of Lisp objects to the corresponding internal object structure.. In the original Lisp, S-expressions consisted only of symbols, integers, and the list constructors ( x i...
The off-side rule describes syntax of a computer programming language that defines the bounds of a code block via indentation. [1] [2]The term was coined by Peter Landin, possibly as a pun on the offside law in association football.
Written in the C programming language, libxml2 provides bindings to C++, Ch, [3] XSH, C#, Python, Swift, Kylix/Delphi and other Pascals, Ruby, Perl, Common Lisp, [4] and PHP. [5] It was originally developed for the GNOME project , but can be used outside it. libxml2's code is highly portable [ 6 ] since it only depends on standard ANSI C ...
A Computational Logic for Applicative Common Lisp consists of a programming language, an extensible theory in a first-order logic, and a mechanical theorem prover [3] Arc: 2008: Paul Graham: Dialect of Lisp developed by Paul Graham and Robert Morris [4] AutoLISP: 1986: David Betz: Built to include and use with the full version of AutoCAD and ...
However, parser generators for context-free grammars often support the ability for user-written code to introduce limited amounts of context-sensitivity. (For example, upon encountering a variable declaration, user-written code could save the name and type of the variable into an external data structure, so that these could be checked against ...

Yacc (Yet Another Compiler-Compiler) is a computer program for the Unix operating system developed by Stephen C. Johnson.It is a lookahead left-to-right rightmost derivation (LALR) parser generator, generating a LALR parser (the part of a compiler that tries to make syntactic sense of the source code) based on a formal grammar, written in a notation similar to Backus–Naur form (BNF).

Semantically, CGOL is essentially just Common Lisp, with some additional reader and printer support. CGOL may be regarded as a more successful incarnation of some of the essential ideas behind the earlier LISP 2 project. Lisp 2 was a successor to LISP 1.5 that aimed to provide ALGOL syntax. LISP 2 was abandoned, whereas it is possible to use ...
