Dialog (software)
Dialog is an application used in shell scripts which displays text user interface widgets. It uses the curses or ncurses library. The latter provides users with the ability to use a mouse, e.g., in an xterm. Dialog was created by Savio Lam (first reported version 0.3 was in 1994). It was further modified by several people. Since 1999 it has been maintained (and rewritten) by Thomas Dickey. At least one fork exists, a FreeBSD FreeBSD is a free and open-source Unix-like operating system descended from the Berkeley Software Distribution (BSD), which was based on Research Unix. The first version of FreeBSD was released in 1993. In 2005, FreeBSD was the most popular ...-only split into application and library in late 1994. One might also consider lxdialog (part of menuconfig), except that it has been reduced to fragments that can no longer run dialog scripts. There are several programs inspired by dialog; not all read the same scripts. The most well-known are Xdialog and w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Dickey
Lynx is a customizable text-based web browser for use on cursor-addressable character cell terminals. , it is the oldest web browser still being maintained, having started in 1992. History Lynx was a product of the Distributed Computing Group within Academic Computing Services of the University of Kansas, and was initially developed in 1992 by a team of students and staff at the university (Lou Montulli, Michael Grobe and Charles Rezac) as a hypertext browser used solely to distribute campus information as part of a ''Campus-Wide Information Server'' and for browsing the Gopher space. Beta availability was announced to Usenet on 22 July 1992. In 1993, Montulli added an Internet interface and released a new version (2.0) of the browser. the support of communication protocols in Lynx is implemented using a version of libwww, forked from the library's code base in 1996. The supported protocols include Gopher, HTTP, HTTPS, FTP, NNTP and WAIS. Support for NNTP was added to l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xterm
In computing, xterm is the standard terminal emulator for the X Window System. It allows users to run programs which require a command-line interface. If no particular program is specified, xterm runs the user's shell. An X display can show one or more user's xterm windows output at the same time. Each xterm window is a separate process, but all share the same keyboard, taking turns as each xterm process acquires ''focus''. Normally focus switches between X applications as the user moves the pointer (e.g., a mouse cursor) about the screen, but xterm provides options to ''grab focus'' (the ''Secure Keyboard'' feature) as well as accept input events sent without using the keyboard (the ''Allow SendEvents'' feature). Those options have limitations, as discussed in the xterm manual. xterm originated prior to the X Window System. It was originally written as a stand-alone terminal emulator for the VAXStation 100 (VS100) by Mark Vandevoorde, a student of Jim Gettys, in the ...

Software That Uses Ncurses
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zenity
Zenity is free software and a cross-platform program that allows the execution of GTK dialog boxes in command-line and shell scripts. Description Like tools such as whiptail and dialog, Zenity allows easy creation of GUIs, though it has fewer features than more complex GUI-creation tools. Cross-platform compatibility , Zenity is available for Linux, BSD and Windows. A Zenity port to Mac OS X is available in MacPorts and Homebrew. As of 2018, Zenity ports for Windows are availablezenity-windows(based on version 3.20.0) anwinzenity(based on 3.8.0 / statically linked) Zenity does not possess any built-in scripting capabilities and it must, therefore, rely on an interpreter for processing. To create a script that runs on more than one platform without extensive modifications, it would be best to use an interpreter that is available on the widest range of operating systems. One option is Python in combination with the PyZenity library. Examples Python example fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CDK (programming Library)
CDK is a library written in C that provides a collection of widgets for text user interfaces (TUI) development. The widgets wrap ncurses functionality to make writing full screen curses programs faster. Perl and Python bindings are also available. There are two versions of the library. It was originally written by Mike Glover, introduced as version 4.6 in comp.sources.unix. The other version was extended beginning in May 1999 by Thomas Dickey.

Newt (programming Library)
Newt is a programming library for color text mode, widget-based user interfaces. Newt can be used to add stacked windows, entry widgets, checkboxes, radio buttons, labels, plain text fields, scrollbars, etc., to text user interfaces. This package also contains the shared library needed by programs built with newt, as well as an application whiptail, which provides the most commonly used features of dialog. Newt is based on the slang library. It abbreviates from ''Not Erik's Windowing Toolkit''. Features Newt was originally designed for use in the install code of Red Hat Linux and is written mostly focusing on clear interface, simplicity and small footprint. Because of that, unlike most recent GUI engines, it does not use an event-driven architecture. Windows must be created and destroyed as a stack (the order of discarding is the exact opposite to that of creation). The top level window is always modal. Many behaviours, such as widget traversal order, are difficult or im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menuconfig
make menuconfig is one of five similar tools that can configure Linux source, a necessary early step needed to compile the source code. make menuconfig, with a menu-driven user interface, allows the user to choose the features of Linux (and other options) that will be compiled. It is normally invoked using the command make menuconfig; menuconfig is a target in Linux Makefile. History make menuconfig was not in the first version of Linux. The predecessor tool is a question-and-answer-based utility (make config, make oldconfig). A third tool for Linux configuration is make xconfig, which requires Qt. There is also make gconfig, which uses GTK+, and make nconfig, which is similar to make menuconfig. All these tools use the Kconfig language internally. Kconfig is also used in other projects, such as Das U-Boot, a bootloader for embedded devices, Buildroot, a tool for generating embedded Linux systems, and BusyBox, a single-executable shell utility toolbox for embedded systems. ...

FreeBSD
FreeBSD is a free and open-source Unix-like operating system descended from the Berkeley Software Distribution (BSD), which was based on Research Unix. The first version of FreeBSD was released in 1993. In 2005, FreeBSD was the most popular open-source BSD operating system, accounting for more than three-quarters of all installed and permissively licensed BSD systems. FreeBSD has similarities with Linux, with two major differences in scope and licensing: FreeBSD maintains a complete system, i.e. the project delivers a kernel, device drivers, userland utilities, and documentation, as opposed to Linux only delivering a kernel and drivers, and relying on third-parties for system software; FreeBSD source code is generally released under a permissive BSD license, as opposed to the copyleft GPL used by Linux. The FreeBSD project includes a security team overseeing all software shipped in the base distribution. A wide range of additional third-party applications may be i ...

Fork (software Development)
In software engineering, a project fork happens when developers take a copy of source code from one software package and start independent development on it, creating a distinct and separate piece of software. The term often implies not merely a development branch, but also a split in the developer community; as such, it is a form of schism. Grounds for forking are varying user preferences and stagnated or discontinued development of the original software. Free and open-source software is that which, by definition, may be forked from the original development team without prior permission, and without violating copyright law. However, licensed forks of proprietary software (''e.g.'' Unix) also happen. Etymology The word "fork" has been used to mean "to divide in branches, go separate ways" as early as the 14th century. In the software environment, the word evokes the fork system call, which causes a running process to split itself into two (almost) identical copies that ...

Ncurses
ncurses (new curses) is a programming library providing an application programming interface (API) that allows the programmer to write text-based user interfaces (TUI) in a terminal-independent manner. It is a toolkit for developing "GUI-like" application software that runs under a terminal emulator. It also optimizes screen changes, in order to reduce the latency experienced when using remote shells. ncurses is a free-software emulation of the System V Release 4.0 (SVr4) curses. There are bindings for ncurses in a variety of programming languages, including Ada, Python, Gambas, Ruby, PHP, JavaScript, and Perl. History As the new version, ncurses is a free-software emulation of the System V Release 4.0 (SVr4) curses, which was itself an enhancement over the discontinued 4.4 BSD curses. The XSI Curses standard issued by X/Open is explicitly and closely modeled on System V. curses The first curses library was developed at the University of California at Berkeley, for ...

Unix
Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft ( Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). In the early 1990s, AT&T sold its rights in Unix to Novell, which then sold the UNIX trademark to The Open Group, an industry consortium founded in 1996. The Open Group allows the use of the mark for certified operating systems that comply with the Single UNIX Specification (SUS). Unix systems are characterized by a modular design that is sometimes called the " Unix philosophy". According to thi ... [...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). 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 specific capabilities and control sequences. In short, this means that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
