S-Lang
The S-Lang programming library is a software library for Unix, Windows, VMS, OS/2, and Mac OS X. It provides routines for embedding an interpreter for the S-Lang scripting language, and components to facilitate the creation of text-based applications. The latter class of functions include routines for constructing and manipulating keymaps, an interactive line-editing facility, and both low- and high-level screen/terminal management functions. It is distributed under the terms of the GNU General Public License. Brief history The S-Lang programming library was started in 1992 by John E. Davis, considering that functions he wrote for a text editor might be useful in other programs. The earliest version of the library contained input/output routines for interacting with computer terminals and an implementation of a simple stack-based interpreter with a PostScript-like syntax that he developed for use in a scientific plotting program. The JED text editor was the first program to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JED (text Editor)
JED is a text editor that makes extensive use of the S-Lang programming library and language. It is highly cross-platform compatible; JED runs on Windows and all flavors of Linux and Unix. Older versions are available for DOS. It is also very lightweight (meaning very parsimonious in its use of system resources), which makes it an ideal editor for older systems, embedded systems, etc. JED's Emacs mode is one of the most faithful emulations available. Features From the JED homepage: *Color syntax highlighting on color terminals *Code folding support *Drop-down menus on all terminals and platforms *Emulates editors Emacs, EDT, WordStar, Borland, Brief *Extensible in the C-like language S-Lang, making the editor highly customizable *Can read Texinfo (GNU info) files from within JED's info browser *A variety of programming modes (with syntax highlighting) are available including C, C++, Fortran, TeX, HTML, Bourne shell (sh), Perl, Python, IDL, DIGITAL Command Language (DCL), ...

Slrn
slrn is a Console application, console-based news client for multiple operating systems, developed by John E. Davis and others. It was originally developed in 1994 for Unix-like operating systems and OpenVMS, VMS, and now also supports Microsoft Windows. It supports scoring rules to highlight, sort or kill articles based on information from their Header (computing), header. It is customizable, allows free Keyboard shortcut, key-bindings and can be extended using the S-Lang macro language. Offline reading is possible by using either slrnpull (included with slrn) or a local newsserver (like leafnode or InterNetNews, INN). slrn is free software. slrn was maintained by Thomas Schultz from 2000 to 2007, with the help of others who made contributions, but development is now again followed by the original author, John E. Davis. Current development focuses on better support for different character encoding, character sets and tighter integration of the S-Lang language processor. Version ...

Text-based (computing)
In computing, text-based user interfaces (TUI) (alternately terminal user interfaces, to reflect a dependence upon the properties of computer terminals and not just text), is a retronym describing a type of user interface (UI) common as an early form of human–computer interaction, before the advent of bitmapped displays and modern conventional graphical user interfaces (GUIs). Like modern GUIs, they can use the entire screen area and may accept mouse and other inputs. They may also use color and often structure the display using box-drawing characters such as ┌ and ╣. The modern context of use is usually a terminal emulator. Types of text terminals From text application's point of view, a text screen (and communications with it) can belong to one of three types (here ordered in order of decreasing accessibility): # A genuine text mode display, controlled by a video adapter or the central processor itself. This is a normal condition for a locally running application ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curses (programming Library)
curses is a terminal control library for Unix-like systems, enabling the construction of text user interface (TUI) applications. The name is a pun on the term " cursor optimization". It is a library of functions that manage an application's display on character-cell terminals (e.g., VT100). ncurses is the approved replacement for 4.4BSD classic curses. Overview Using curses, programmers are able to write text-based applications without writing directly for any specific terminal type. The curses library on the executing system sends the correct control characters based on the terminal type. It provides an abstraction of one or more windows that maps onto the terminal screen. Each window is represented by a character matrix. The programmer sets up the desired appearance of each window, then tells the curses package to update the screen. The library determines a minimal set of changes that are needed to update the display and then executes these using the terminal's specifi ...

Mutt (e-mail Client)
Mutt is a text-based email client for Unix-like systems. It was originally written by Michael Elkins in 1995 and released under the GNU General Public License version 2 or any later version. The Mutt slogan is "''All mail clients suck. This one just sucks less.''" Operation Mutt supports most mail storing formats (notably both mbox and Maildir) and protocols (POP3, IMAP, etc.). It also includes MIME support, notably full PGP/ GPG and S/MIME integration. Mutt was originally designed as a Mail User Agent (MUA) and relied on locally accessible mailbox and sendmail infrastructure. According to the Mutt homepage "though written from scratch, Mutt's initial interface was based largely on the ELM mail client". New to Mutt were message scoring and threading capabilities. Support for fetching and sending email via various protocols such as POP3, IMAP and SMTP was added later. However, Mutt still relies on external tools for composing and filtering messages. Mutt has hundreds of confi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Library
In computing, a library is a collection of resources that can be leveraged during software development to implement a computer program. Commonly, a library consists of executable code such as compiled functions and classes, or a library can be a collection of source code. A resource library may contain data such as images and text. A library can be used by multiple, independent consumers (programs and other libraries). This differs from resources defined in a program which can usually only be used by that program. When a consumer uses a library resource, it gains the value of the library without having to implement it itself. Libraries encourage software reuse in a modular fashion. Libraries can use other libraries resulting in a hierarchy of libraries in a program. When writing code that uses a library, a programmer only needs to know how to use it not its internal details. For example, a program could use a library that abstracts a complicated system call so that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MATLAB
MATLAB (an abbreviation of "MATrix LABoratory") is a proprietary multi-paradigm programming language and numeric computing environment developed by MathWorks. MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages. Although MATLAB is intended primarily for numeric computing, an optional toolbox uses the MuPAD symbolic engine allowing access to symbolic computing abilities. An additional package, Simulink, adds graphical multi-domain simulation and model-based design for dynamic and embedded systems. , MATLAB has more than four million users worldwide. They come from various backgrounds of engineering, science, and economics. , more than 5000 global colleges and universities use MATLAB to support instruction and research. History Origins MATLAB was invented by mathematician and computer programmer Cleve Moler. The idea for MATLAB was base ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Widget Toolkit
A widget toolkit, widget library, GUI toolkit, or UX library is a library (computing), library or a collection of libraries containing a set of graphical control elements (called ''widgets'') used to construct the graphical user interface (GUI) of programs. Most widget toolkits additionally include their own Rendering (computer graphics), rendering engine. This engine can be specific to a certain operating system or windowing system or contain back-ends to interface with multiple ones and also with rendering APIs such as OpenGL, OpenVG, or EGL (API), EGL. The look and feel of the graphical control elements can be hard-coded or decoupled, allowing the graphical control elements to be Theme (computing), themed/Skin (computing), skinned. Overview Some toolkits may be used from other languages by employing language bindings. Graphical user interface builders such as e.g. Glade Interface Designer facilitate the authoring of GUIs in a WYSIWYG manner employing a user interface markup la ...

UTF-8
UTF-8 is a character encoding standard used for electronic communication. Defined by the Unicode Standard, the name is derived from ''Unicode Transformation Format 8-bit''. Almost every webpage is transmitted as UTF-8. UTF-8 supports all 1,112,064 valid Unicode code points using a variable-width encoding of one to four one- byte (8-bit) code units. Code points with lower numerical values, which tend to occur more frequently, are encoded using fewer bytes. It was designed for backward compatibility with ASCII: the first 128 characters of Unicode, which correspond one-to-one with ASCII, are encoded using a single byte with the same binary value as ASCII, so that a UTF-8-encoded file using only those characters is identical to an ASCII file. Most software designed for any extended ASCII can read and write UTF-8, and this results in fewer internationalization issues than any alternative text encoding. UTF-8 is dominant for all countries/languages on the internet, with 99% global ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU General Public License
The GNU General Public Licenses (GNU GPL or simply GPL) are a series of widely used free software licenses, or ''copyleft'' licenses, that guarantee end users the freedom to run, study, share, or modify the software. The GPL was the first copyleft license available for general use. It was originally written by Richard Stallman, the founder of the Free Software Foundation (FSF), for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. The licenses in the GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. The GPL is more restrictive than the GNU Lesser General Public License, and even more distinct from the more widely used permissive software licenses such as BSD, MIT, and Apache. Historically, the GPL license family has been one of the most popular software licenses in the free and open-source software (FOSS) domai ...
