    tkPacman

    tkPacman

    A GUI for the 'pacman' package manager of Arch Linux

    tkPacman is a lightweight graphical user interface for 'pacman', the package manager of Arch Linux. It is built with Tcl/Tk. As such it is compatible with all window managers and desktop environments. It only interacts with the package database via the CLI of 'pacman'. So, installing and removing packages with tkPacman or with pacman leads to exactly the same result. tkPacman is started using your normal (unprivileged) user account. You can browse through available and installed packages as a normal user. Anytime, you perform an action that requires 'root' privileges, you are asked to authenticate. tkPacman can use 'su', 'sudo', 'gksu' or 'kdesu'.

    next-scripting

    next-scripting

    Next Scripting Framework (NSF)

    The Next Scripting Framework (NSF) was developed based on the notion of language-oriented programming. The framework allows a language developer to work with multiple object systems on top of Tcl in a single workspace. The developer can benefit from a rich and extensible set of predefined functions (typically implemented in C) which can be registered for use on objects and classes in a given object system. NSF provides a tool box for defining dynamic, object-oriented, and domain-specific languages. NSF ships with 3 fully scripted language definitions, containing XOTcl 2 and the Next Scripting language NX. NX is a highly flexible and object-oriented scripting language. It is a descendant of XOTcl and was designed based on 10 years of experience with XOTcl in projects containing several hundred thousand lines of code. While XOTcl was the first language designed to provide language support for design patterns, NX adds language-oriented programming and higher safety.
