This package provides higher order functions like map,filter, foldl, sort_by and take_while as simple command-line tools. Following the UNIX philosophy, these commands are designed to be composed via pipes. A large collection of functions such as basename, replace, contains or is_dir are provided as arguments to these commands.

This package provides The minimal, blazing-fast, and infinitely customizable prompt for any shell!

• Fast: it's fast - *really really* fast :rocket:

• Customizable: configure every aspect of your prompt

• Universal: works on any shell, on any operating system

• Intelligent: shows relevant information at a glance

• Feature rich: support for all your favorite tools

• Easy: quick to install - start using it in minutes

Note: users must have a nerd font installed and enabled in their terminal

pay-respects provides a shell helper to suggest correction for mistyped commands, with guix locate integration and an alias (default to f) to correct the previous command.

Fish-like fast/unobtrusive autosuggestions for zsh. It suggests commands as you type.

RIG (Random Identity Generator) generates random, yet real-looking, personal data. It is useful if you need to feed a name to a Web site, BBS, or real person, and are too lazy to think of one yourself. Also, if the Web site/BBS/person you are giving the information to tries to cross-check the city, state, zip, or area code, it will check out.

This is a clean-room implementation of the Fish shell's history search feature, where you can type in any part of any command from history and then press chosen keys, such as the UP and DOWN arrows, to cycle through matches.

direnv can hook into the bash, zsh, tcsh, and fish shells to load or unload environment variables depending on the current directory. This allows project-specific environment variables without using ~/.profile.

Before each prompt, direnv checks for the existence of a .envrc file in the current and parent directories. This file is then used to alter the environment variables of the current shell.

Liquidprompt is an adaptive prompt for Bash and Zsh that gives you a nicely displayed prompt with useful information when you need it. It does this with a powerful theming engine and a large array of data sources.

In order to use liquidprompt with Zsh, you should use the following snippet with Guix Home:

(service home-zsh-service-type
         (home-zsh-configuration
           (zshrc (list ;;...
                    ;; This loads liquidprompt
                    (mixed-text-file "liquidprompt"
                                     "[[ $- = *i* ]] && source " liquidprompt "/share/liquidprompt/liquidprompt")
                    ;; This loads the powerline theme available in liquidprompt
                    (mixed-text-file "powerline-theme"
                                     "source " liquidprompt "/share/liquidprompt/themes/powerline/powerline.theme"))))))

The ascii utility provides easy conversion between various byte representations and the American Standard Code for Information Interchange (ASCII) character table. It knows about a wide variety of hex, binary, octal, Teletype mnemonic, ISO/ECMA code point, slang names, XML entity names, and other representations. Given any one on the command line, it will try to display all others. Called with no arguments it displays a handy small ASCII chart.

This Zsh plugin auto-closes, deletes, and skips over matching delimiters in Zsh intelligently.

This projects aims at gathering/developing new completion scripts that are not available in Zsh yet. The scripts may be contributed to the Zsh project when stable enough.

trash-cli is a command line utility for interacting with the FreeDesktop.org trash can used by GNOME, KDE, XFCE, and other common desktop environments. It can move files to the trash, and remove or list files that are already there.

conflict examines the user-specifiable list of programs, looking for instances in the user's path which conflict (i.e., the name appears in more than one point in the path).

This package provides an interactive setup for zsh preconfigured by the Grml project.

Tracks your most used directories, based on ``frecency''. After a short learning phase, z will take you to the most ``frecent'' directory that matches all of the regexes given on the command line in order.

grc can be used to colourise logfiles, output of shell commands, arbitrary text, etc. Many shell commands are supported out of the box.

You might want to add these lines you your ~/.bashrc:

GRC_ALIASES=true
source $GUIX_ENVIRONMENT:-$HOME/.guix-profile/etc/profile.d/grc.sh

Most other fuzzy matchers sort based on the length of a match. fzy tries to find the result the user intended. It does this by favouring matches on consecutive letters and starts of words. This allows matching using acronyms or different parts of the path.

fzy is designed to be used both as an editor plugin and on the command line. Rather than clearing the screen, fzy displays its interface directly below the current cursor position, scrolling the screen if necessary.

This package provides a shell formatter. Supports POSIX Shell, Bash, and mksh.

The file renaming utilities (renameutils for short) are a set of programs designed to make renaming of files faster and less cumbersome. The file renaming utilities consists of five programs: qmv, qcp, imv, icp, and deurlname.

The FEniCS Form Compiler (FFC) is a compiler for finite element variational forms. From a high-level description of the form, it generates efficient low-level C++ code that can be used to assemble the corresponding discrete operator (tensor). In particular, a bilinear form may be assembled into a matrix and a linear form may be assembled into a vector. FFC may be used either from the command line (by invoking the ffc command) or as a Python module (import ffc).

FFC is part of the FEniCS Project.

The Open Simulation Interface is a generic interface based on Google's protocol buffers for the environmental perception of automated driving functions in virtual scenarios.

python-dolfin-adjoint is a solver of differential equations associated with a governing system and a functional of interest. Working from the forward model the solver automatically derives the discrete adjoint and tangent linear models. These additional models are key ingredients in many algorithms such as data assimilation, optimal control, sensitivity analysis, design optimisation and error estimation. The dolfin-adjoint project provides the necessary tools and data structures for cases where the forward model is implemented in fenics or firedrake.

OpenFOAM provides a set of solvers and methods for tackling problems in the field of Computational Fluid Dynamics (CFD). It is written in C++. Governing equations such as the Navier-Stokes equations can be solved in integral form. Physical processes such as phase change, droplet transport and chemical reaction can be modelled. Numerical methods are included to deal with sharp gradients, such as those encountered in flows with shock waves and flows with gas/liquid interfaces. Large problems may be split into smaller, connected problems for efficient solution on parallel systems.
