Hemlock (text Editor)
Hemlock is a free Emacs text editor for most POSIX-compliant Unix systems. It follows the tradition of the Lisp Machine editor ZWEI and the ITS/TOPS-20 implementation of Emacs, but differs from XEmacs or GNU Emacs, the most popular Emacs variants, in that it is written in Common Lisp rather than Emacs Lisp and C—although it borrows features from the later editors. Hemlock was originally written by the CMU Spice project in Spice Lisp (later renamed to CMU Common Lisp) for the PERQ computer. Hemlock is integrated with the Common Lisp compiler, interpreter, and development suite CMU Common Lisp, though it is possible to use it as a standalone editor, or to use GNU Emacs with CMUCL instead—Hemlock integrates better, but has fewer features and addon programs. One distinctive feature is that Hemlock distinguishes Lisp function names from interactive command names, which are given in a more natural-language-like style derived from the original MIT Lisp Machine editor Zmacs and TEC ...

Free Software
Free software or libre software is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of liberty, not price; all users are legally free to do what they want with their copies of a free software (including profiting from them) regardless of how much is paid to obtain the program.Selling Free Software (gnu.org) Computer programs are deemed "free" if they give end-users (not just the developer) ultimate control over the software and, subsequently, over their devices. The right to study and modify a computer program entails that |
CMU Common Lisp
CMUCL is a free Common Lisp implementation, originally developed at Carnegie Mellon University. CMUCL runs on most Unix-like platforms, including Linux and BSD; there is an experimental Windows port as well. Steel Bank Common Lisp is derived from CMUCL. The Scieneer Common Lisp is a commercial derivative from CMUCL. History The earliest implementation predates Common Lisp and was part of Spice Lisp, around 1980. In 1985 Rob MacLachlan started re-writing the compiler to what would become the Python compiler and CMUCL was ported to Unix workstations such as the IBM PC RT, MIPS and SPARC. Early CMUCL releases did not support Intel's x86 architecture due to a lack of registers. CMUCL strictly separated type-tagged and immediate data types and the garbage collector would rely on knowing that one half of the CPU registers could only hold tagged types and the other half only untagged types. This did not leave enough registers for a Python backend. After CMU canceled the project ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CLiki
CLiki is an open source wiki application Wiki software (also known as a wiki engine or a wiki application), is collaborative software that runs a wiki, which allows the users to create and collaboratively edit pages or entries via a web browser. A wiki system is usually a web application ... written in Common Lisp, that was under development from 2002 to 2005. CLiki was first presented at the International Lisp Conference 2002. CLiki was the first wiki variant to introduce so called "free links", using the _(free link format) as an alternative to the much-criticized CamelCase. The CLiki program is free software licensed under the MIT license. It runs under SBCL and uses the Araneida Common Lisp web server. CLiki also operates a homepage using the software that is dedicated to the subject of Common Lisp. Cliki2 Since 2011, a new version of Cliki (named ''Cliki2'') was developed by Vladimir Sedach and Andrey Moskvitin, with major features around spam prevention. Other major fe ...

PostScript
PostScript (PS) is a page description language in the electronic publishing and desktop publishing realm. It is a dynamically typed, concatenative programming language. It was created at Adobe Systems by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton from 1982 to 1984. History The concepts of the PostScript language were seeded in 1976 by John Gaffney at Evans & Sutherland, a computer graphics company. At that time Gaffney and John Warnock were developing an interpreter for a large three-dimensional graphics database of New York Harbor. Concurrently, researchers at Xerox PARC had developed the first laser printer and had recognized the need for a standard means of defining page images. In 1975-76 Bob Sproull and William Newman developed the Press format, which was eventually used in the Xerox Star system to drive laser printers. But Press, a data format rather than a language, lacked flexibility, and PARC mounted the Interpress effort to create a succ ...

Clozure CL
Clozure CL (CCL) is a Common Lisp implementation. It implements the full ANSI Common Lisp standard with several extensions ( CLOS MOP, threads, CLOS conditions, CLOS streams, ...). It contains a command line development environment, an experimental integrated development environment (IDE) for Mac OS X using the Hemlock editor, and can also be used with SLIME (a Common Lisp development environment for GNU Emacs). Clozure CL is open source and the project is hosted by Clozure Associates. Supported platforms Clozure CL supports the Mac OS X, Linux, FreeBSD, Solaris and Microsoft Windows platforms. There are 32 and 64 bit x86 variants for each. Additionally, there are PowerPC ports for Mac OS X and Linux, and a 32-bit ARM port for Linux. Applications Clozure CL was used by ITA Software for the business logic of a new Airline Reservation System. Clozure CL is also commonly used as an underlying Common Lisp implementation for the ACL2 theorem prover. History Formerly kn ...

X Window System
The X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems. X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard. X does not mandate the user interfacethis is handled by individual programs. As such, the visual styling of X-based environments varies greatly; different programs may present radically different interfaces. X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. The X protocol has been at version 11 (hence "X11") since September 1987. The X.Org Foundation leads the X project, with the current reference implementation, X.Org Server, available as free and open-source software under the MIT License and similar permissive licenses. Purpose and abilities X is an architecture-independent system for remote graphical user interfaces and input device capabilities. Each person using a ...

Computer Terminal
A computer terminal is an electronic or electromechanical hardware device that can be used for entering data into, and transcribing data from, a computer or a computing system. The teletype was an example of an early-day hard-copy terminal and predated the use of a computer screen by decades. Early terminals were inexpensive devices but very slow compared to punched cards or paper tape for input, yet as the technology improved and video displays were introduced, terminals pushed these older forms of interaction from the industry. A related development was time-sharing systems, which evolved in parallel and made up for any inefficiencies in the user's typing ability with the ability to support multiple users on the same machine, each at their own terminal or terminals. The function of a terminal is typically confined to transcription and input of data; a device with significant local, programmable data-processing capability may be called a "smart terminal" or fat client.

Text Editor And Corrector
TECO (), short for ''Text Editor & Corrector'',"A powerful and sophisticated text editor, TECO (Text Editor and Corrector) ... is both a character-oriented text editor and a programming language, that was developed in 1962 for use on Digital Equipment Corporation computers, and has since become available on PCs and Unix. Dan Murphy developed TECO while a student at the Massachusetts Institute of Technology (MIT). According to Murphy, the initial acronym was ''Tape Editor and Corrector'' because "punched paper tape was the only medium for the storage of program source on our PDP-1. There was no hard disk, floppy disk, magnetic tape (magtape), or network." By the time TECO was made available for general use, the name had become "Text Editor and Corrector", since even the PDP-1 version by then supported other media. It was subsequently modified by many other people and is a direct ancestor of Emacs, which was originally implemented in TECO macros. Description TECO is not only an ed ...

Zmacs
Zmacs is one of the many variants of the Emacs text editor. Zmacs was written for the MIT Lisp machine and runs on its descendants (Symbolics Genera, LMI Lambda, TI Explorer). Zmacs is written in Lisp Machine Lisp (called ZetaLisp on Symbolics Lisp Machines). It is based on the ZWEI programming substrate, which stands for "Zwei Was EINE Initially"; Zwei was a collection of routines which could be used to easily implement other programs, like the Symbolics mail program, ''Zmail''. A distinctive feature of Zmacs, which can also be found in Hemlock and LispWorks, is that commands look like instead of as modern Emacsen, like GNU Emacs, generally format commands. Zmacs also supports buffers and modes. Zmacs also uses the window system of the Lisp Machine with support for mouse and windows. Zmacs supports unlimited backup of files, since the file system of the Lisp Machine supports file versions. It is not compatible with GNU Emacs and its Emacs Lisp. External links Zmacs Ma ...
