    Babashka

    Babashka

    Native, fast starting Clojure interpreter for scripting

    Avoid switching between Clojure and bash scripts. Enjoy your parens on the command line. Leveraging GraalVM native-image and the Small Clojure Interpreter, babashka is a self-contained and instantly starting scripting environment. Babashka comes with scripting batteries included: tools.cli, cheshire, babashka.fs, babashka.process, java.time and many more libraries and classes. Babashka scripts work on linux, macOS and Windows. Besides the built-in libraries, babashka is able to load libraries from source, tapping into the world of already existing Clojure libraries. Babashka supports real JVM threads and like Clojure, supports futures and dynamic thread-locally bound vars. Babashka features a built-in task runner which covers the most popular use cases of make, just and npm scripts. Babashka can shell out to other CLI programs like you are used to in bash. It goes one step further and offers seamless integration with other binaries using the pod protocol.

    fish

    fish

    The user-friendly command line shell

    Finally, a command line shell for the 90s. fish is a smart and user-friendly command line shell for Linux, macOS, and the rest of the family. fish suggests commands as you type based on history and completions, just like a web browser. Watch out, Netscape Navigator 4.0! fish supports 24 bit true color, the state of the art in terminal technology. Behold the monospaced rainbow. fish is fully scriptable, and its syntax is simple, clean, and consistent. You'll never write esac again. For those lucky few with a graphical computer, you can set your colors and view functions, variables, and history all from a web page. Other shells support programmable completions, but only fish generates them automatically by parsing your installed man pages. fish will delight you with features like tab completions and syntax highlighting that just work, with nothing new to learn or configure.

    bash-completion

    bash-completion

    Programmable completion functions for bash

    bash-completion is a collection of command-line command completions for the Bash shell, a collection of helper functions to assist in creating new completions, and a set of facilities for loading completions automatically on-demand, as well as installing them. The easiest way to install this software is to use a package; refer to Repology for a comprehensive list of operating system distributions, package names, and available versions. Depending on the package, you may still need to source it from either /etc/bashrc or ~/.bashrc (or any other file sourcing those). If you don't have the package readily available for your distribution, or you simply don't want to use one, you can install bash-completion using the standard commands for GNU Autotools packages. If you find that a given function is producing errors or does not work as it should under certain circumstances when you attempt completion, try running set -x or set -v prior to attempting the completion again.

    Extreme ultimate .bashrc configuration file for Bash

    Do you want a more robust experience from your bash shell? As a Linux systems administrator, I've been working on this .bashrc file for well over a decade.

It will detect most settings on most systems and make sure your environment has every feature available automatically without any additional effort. Do you need a command line cheat sheet?

    kube-ps1

    kube-ps1

    Kubernetes prompt info for bash and zsh

    A script that lets you add the current Kubernetes context and namespace configured on kubectl to your Bash/Zsh prompt strings (i.e. the $PS1). The default prompt assumes you have the kubectl command-line utility installed. Official installation instructions and binaries are available. Blue was used for the default symbol to match the Kubernetes color as closely as possible. Red was chosen as the context name to stand out, and cyan for the namespace. 256 colors are available by specifying the numerical value as the variable argument. Due to the vast ways of customizing the shell, please try the prompt with a minimal configuration before submitting a bug report.

    Kobo XCSoar Launcher

    a customizable boot menu for your Kobo Mini

    Mainly this project aims at easing startup and use of XCSoar (see xcsoar.org) on Kobo Mini. But the scope of use should not be limited solely to XCSoar. The Launcher should be small in code size, reuse most of the original libraries, provide flexible configuration to any application that might be ported to the Kobo Mini. It supports customizable fonts, toolbox-pages, buttons (also graphical), labels, autostart and sleep timers.

    Extreme Ultimate Tmux

    Extreme Ultimate Tmux

    Portable tmux config with menus, app launcher, tray icon. No plugins.

    Do you want the power of a fully loaded tmux plugin framework without installing a single plugin? One file. No plugin managers. No dependencies. No setup. Drop it on any machine and it just works. What you get feels like a desktop app: a menu system with submenus, a 21-app launcher, searchable help, a built-in scratchpad, a system dashboard, and a fully clickable status bar. All in a beautiful adaptive interface that auto-detects your fonts and scales from Nerd Font icons to plain ASCII on a TTY. The status bar knows when you are in SSH and moves out of the way. The clipboard works everywhere including over SSH. Every feature degrades gracefully. Nothing breaks if a tool is missing. To install: wget -O ~/.tmux.conf https://sourceforge.net/projects/ultimate-tmux/files/_tmux.conf/download Also includes: system tray icon (tmux-tray), terminal launchers for 5 terminals, and a WezTerm config. Companion: Extreme Ultimate .bashrc (sourceforge.net/projects/ultimate-bashrc)
