Ups (debugger)
Ups is an open source source-level debugger developed in the late 1980s for Unix and Unix-like systems, originally developed at the University of Kent by Mark Russell. It supports C and C++, and Fortran on some platforms. The last beta release was in 2003. Unlike more popular debugger stacks for modern Unix platforms, ''ups'' is completely self-contained — not merely a graphical front-end to lower-level debuggers like gdb (although some work has been done to make ''ups'' usable in that way). The ''ups'' user interface is built directly upon the X Window System and SunView, i.e. it does not use an intermediate widget toolkit such as Motif or GTK+.

Open-source License
Open-source licenses are software licenses that allow content to be used, modified, and shared. They facilitate free and open-source software (FOSS) development. Intellectual property (IP) laws restrict the modification and sharing of creative works. Free and open-source licenses use these existing legal structures for an inverse purpose. They Grant (law), grant the recipient the rights to use the software, examine the source code, modify it, and distribute the modifications. These criteria are outlined in the Open Source Definition. After 1980, the United States began to treat software as a literary work covered by copyright law. Richard Stallman founded the free software movement in response to the rise of proprietary software. The term "open source" was used by the Open Source Initiative (OSI), founded by free software developers Bruce Perens and Eric S. Raymond. "Open source" emphasizes the strengths of the Open-source software development, open development model rather tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 networked computer terminal, terminal has the ability to interact with the display with any type of user input device. In its standard distribution it is a complete, albeit simple, display and interface solution which delivers a standard widget toolkit, toolkit and protocol stack for building graphical user interfaces on most Unix-like operating syst ...

Data Display Debugger
Data Display Debugger (GNU DDD) is a graphical user interface (using the Motif toolkit) for command-line debuggers such as GDB, DBX, JDB, HP Wildebeest Debugger, XDB, the Perl debugger, the Bash debugger, the Python debugger, and the GNU Make debugger. DDD is part of the GNU Project and distributed as free software under the GNU General Public License. Technical details DDD has GUI front-end features such as viewing source texts and its interactive graphical data display, where data structures are displayed as graphs. DDD is used primarily on Unix systems, and its usefulness is complemented by many open source plug-ins available for it.

GTK+
GTK (formerly GIMP ToolKit and GTK+) is a free software cross-platform widget toolkit for creating graphical user interfaces (GUIs). It is licensed under the terms of the GNU Lesser General Public License, allowing both free and proprietary software to use it. It is one of the most popular toolkits for the Wayland and X11 windowing systems. The GTK team releases new versions on a regular basis. GTK 4 and GTK 3 are maintained, while GTK 2 is end-of-life. GTK1 is independently maintained by the CinePaint project. Software architecture The GTK library contains a set of graphical control elements ( widgets); version 3.22.16 contains 186 active and 36 deprecated widgets. GTK is an object-oriented widget toolkit written in the programming language C; it uses GObject (that is, the GLib object system) for object orientation. While GTK is mainly used with windowing systems based on X11 and Wayland, it works on other platforms, including Microsoft Windows ( ...

Motif (software)
In computing, Motif refers to both a graphical user interface (GUI) specification and the widget toolkit for building applications that follow that specification under the X Window System on Unix and Unix-like operating systems. The Motif look and feel is distinguished by its use of rudimentary square and chiseled three-dimensional effects for its various user interface elements. Motif is the toolkit for the Common Desktop Environment and IRIX Interactive Desktop, thus it was the standard widget toolkit for Unix. Closely related to Motif is the Motif Window Manager (MWM). After many years as proprietary software, Motif was released in 2012, as free software under the GNU Lesser General Public License (LGPL-2.1-or-later). History Motif was created by the Open Software Foundation (OSF) to be a standard graphical user interface for Unix platforms. Rather than create a new interface from scratch, OSF opened a Request For Technology (RFT) in 1988 to solicit existing technologies ...

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 ...

SunView
SunView (Sun Visual/Integrated Environment for Workstations) is a discontinued user interface toolkit and windowing system from Sun Microsystems, launched in 1985, and included as part of its Unix implementation, starting with SunOS Release 3.0. Sun had introduced support in 1983 for a window-based environment known as the Sun Window System, providing the Sunwindows (or SunWindows) window manager and Suntools (or SunTools) user interface toolkit. SunWindows was one of the first widely used Unix window systems and, unlike later Unix windowing systems, relied on dedicated support in the system kernel, albeit limited to window hierarchy management and therefore being less invasive than other early window system implementations. In SunWindows, graphics device operations were performed by applications and not in the kernel. SunView was introduced as an object-oriented toolkit layer on top of the SunWindows platform to address the increasing complexity of the underlying system and t ...

GNU Debugger
The GNU Debugger (GDB) is a portable debugger that runs on many Unix-like systems and works for many programming languages, including Ada, Assembly, C, C++, D, Fortran, Haskell, Go, Objective-C, OpenCL C, Modula-2, Pascal, Rust, and partially others. It detects problems in a program while letting it run and allows users to examine different registers. History GDB was first written by Richard Stallman in 1986 as part of his GNU system, after his GNU Emacs was "reasonably stable". GDB is free software released under the GNU General Public License (GPL). It was modeled after the DBX debugger, which came with Berkeley Unix distributions. From 1990 to 1993 it was maintained by John Gilmore. Now it is maintained by the GDB Steering Committee which is appointed by the Free Software Foundation. Technical details Features GDB offers extensive facilities for tracing and altering the execution of computer programs. The user can monitor and modify the values of programs' intern ...

Source Code
In computing, source code, or simply code or source, is a plain text computer program written in a programming language. A programmer writes the human readable source code to control the behavior of a computer. Since a computer, at base, only understands machine code, source code must be Translator (computing), translated before a computer can Execution (computing), execute it. The translation process can be implemented three ways. Source code can be converted into machine code by a compiler or an assembler (computing), assembler. The resulting executable is machine code ready for the computer. Alternatively, source code can be executed without conversion via an interpreter (computing), interpreter. An interpreter loads the source code into memory. It simultaneously translates and executes each statement (computer science), statement. A method that combines compilation and interpretation is to first produce bytecode. Bytecode is an intermediate representation of source code tha ...

Debugger Front-end
A debugger is a computer program used to software testing, test and debugging, debug other programs (the "target" programs). Common features of debuggers include the ability to run or halt the target program using breakpoints, stepping (debugging), step through code line by line, and display or modify the contents of memory, CPU registers, and stack frames. The code to be examined might alternatively be running on an ''instruction set simulator'' (ISS), a technique that allows great power in its ability to halt when specific conditions are encountered, but which will typically be somewhat slower than executing the code directly on the appropriate (or the same) processor. Some debuggers offer two modes of operation, full or partial simulation, to limit this impact. An exception occurs when the program cannot normally continue because of a software bug, programming bug or invalid data. For example, the program might have tried to use an instruction not available on the current ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
