Notcurses
blingful character graphics/TUI library. definitely not curses
A library facilitating complex TUIs on modern terminal emulators, supporting vivid colors, multimedia, threads, and Unicode to the maximum degree possible. Things can be done with Notcurses that simply can't be done with NCURSES. It is furthermore fast as shit. What it is not: a source-compatible X/Open Curses implementation, nor a replacement for NCURSES on existing systems. Notcurses abandons the X/Open Curses API bundled as part of the Single UNIX Specification. For some necessary background, consult Thomas E. Dickey's superb and authoritative NCURSES FAQ. As such, Notcurses is not a drop-in Curses replacement. Wherever possible, Notcurses makes use of the Terminfo library shipped with NCURSES, benefiting greatly from its portability and thoroughness. Notcurses opens up advanced functionality for the interactive user on workstations, phones, laptops, and tablets, possibly at the expense of e.g. some industrial and retail terminals. -

PathPicker
Accepts a wide range of input, output from git commands & grep results
PathPicker accepts a wide range of input, output from git commands, grep results, searches, pretty much anything. After parsing the input, PathPicker presents you with a nice UI to select which files you're interested in. After that you can open them in your favorite editor or execute arbitrary commands. Facebook PathPicker is a simple command line tool that solves the perpetual problem of selecting files out of bash output. Bash is fully supported and works the best. ZSH is supported as well, but won't have a few features like alias expansion in command line mode. csh/fish/rc are supported in the latest version, but might have quirks or issues in older versions of PathPicker. Note: if your default shell and current shell is not in the same family (bash/zsh... v.s. fish/rc), you need to manually export environment variable $SHELL to your current shell. -

Percollate
A command-line tool to turn web pages into beautiful, readable PDF
Percollate is a command-line tool that turns web pages into beautifully formatted PDF, EPUB, or HTML files. By default, percollate processes URLs in parallel. Use the --wait option to process them sequentially instead, with a pause between items. The delay is specified in seconds, and can be zero. By default, percollate bundles all web pages in a single file. Use the --individual flag to export each source to a separate file. Additional CSS styles you can pass from the command line to override styles specified by the default/custom stylesheet. Generate a hyperlinked table of contents. The option is implicitly enabled when bundling more than one web page to a single file. Disable this implicit behavior by passing the --no-to flag. The idea with percollate is to make PDFs that can be printed without losing where the hyperlinks point to. However, for some link-heavy pages, the appended hrefs can become bothersome. -

Roslynator
A collection of 500+ analyzers, refactorings and fixes for C#
A collection of 500+ analyzers, refactorings, and fixes for C#, powered by Roslyn. Roslynator client libraries are meant to be used for the development of your own analyzers/refactorings. It does not contain any analyzers/refactorings themselves. All analyzers in package Roslynator.Formatting.Analyzers are disabled by default. Roslynator Testing Framework can be used for unit testing of analyzers, refactorings and code fix. The framework is distributed as a NuGet package. Some analyzers require options to be set. For this purpose, there is special analyzer ROS0003 that report a diagnostic if an analyzer is enabled but the required option is not set. ROS0003 is disabled by default. If you want to configure Roslynator on a user-wide basis you have to use the Roslynator config file. The default configuration file can be used with an extension for Visual Studio or VS Code. -

aws-encryption-sdk-cli
CLI wrapper around aws-encryption-sdk-python
This command line tool can be used to encrypt and decrypt files and directories using the AWS Encryption SDK. If you have not already installed cryptography, you might need to install additional prerequisites as detailed in the cryptography installation guide for your operating system. Installation using a python virtual environment is recommended to avoid conflicts between system packages and user-installed packages. For the most part, the behavior of aws-encryption-cli in handling files is based on that of GNU CLIs such as cp. A qualifier to this is that when encrypting a file, if a directory is provided as the destination, rather than creating the source filename in the destination directory, a suffix is appended to the destination filename. By default the suffix is .encrypted when encrypting and .decrypted when decrypting, but a custom suffix can be provided by the caller if desired. -

go-wkhtmltopdf
Golang commandline wrapper for wkhtmltopdf
We needed a way to generate PDF documents from Go. These vary from invoices with highly customizable layouts to reports with tables, graphs and images. In our opinion, the best way to do this was by using HTML/CSS templates as a source for our PDFs. Using CSS print media types and millimeters instead of pixel units we can generate very accurate PDF documents using wkhtmltopdf. It takes care of setting the correct order of options as these can become very long with multiple pages where you have page and TOC options for each page. It makes usage in server-type applications easier, every instance (PDF process) has its own output buffer which contains the PDF output and you can feed one input document from an io.Reader (using stdin in wkhtmltopdf). You can combine any number of external HTML documents (HTTP(S) links) with at most one HTML document from stdin and set options for each input document. -

q - Text as Data
Run SQL directly on CSV or TSV files
q is a command line tool that allows direct execution of SQL-like queries on CSVs/TSVs (and any other tabular text files). q treats ordinary files as database tables, and supports all SQL constructs, such as WHERE, GROUP BY, JOINs etc. It supports automatic column name and column type detection, and provides full support for multiple encodings. q fully supports all types of encoding. Use -e data-encoding to set the input data encoding, -Q query-encoding to set the query encoding, and use -E output-encoding to set the output encoding. Sensible defaults are in place for all three parameters. Files with BOM: Files which contain a BOM (Byte Order Mark) are not properly supported inside python's csv module. q contains a workaround that allows reading UTF8 files which contain a BOM - Use -e utf-8-sig for this. The plan is to separate the BOM handling from the encoding itself, which would allow to support BOMs for all encodings. -

skills
The open agent skills tool - npx skills
skills is a CLI that turns “agent skills” into a portable, installable ecosystem, letting developers add reusable instruction sets to many different coding agents from a single command. Instead of hardcoding prompts per tool, it standardizes skills as SKILL.md files with structured metadata so they can be discovered, listed, installed, updated, and version-tracked consistently. The CLI supports pulling skills from common git sources, including GitHub shorthand, full URLs, direct paths inside repos, GitLab URLs, generic git remotes, and even local folders. It is designed to work across a wide range of agents and editors, so one skill package can be installed into multiple agent-specific directories without rewriting anything for each environment. It also supports both interactive and automation-friendly flows, including non-interactive installs for CI and bulk installs for all skills, which makes it usable for teams that want consistent agent capability across machines. -

Ansible Molecule
Molecule aids in the development and testing of Ansible roles
Molecule project is designed to aid in the development and testing of Ansible roles. Molecule provides support for testing with multiple instances, operating systems and distributions, virtualization providers, test frameworks and testing scenarios. Molecule encourages an approach that results in consistently developed roles that are well-written, easily understood and maintained. Molecule supports only the latest two major versions of Ansible (N/N-1), meaning that if the latest version is 2.9.x, we will also test our code with 2.8.x. Depending on the driver chosen, you may need to install additional OS packages. See INSTALL.rst, which is created when initializing a new scenario. Ansible is not listed as a direct dependency of molecule package because we only call it as a command-line tool. You may want to install it using your distribution package installer. It is your responsibility to assure that soft dependencies of Ansible are available on your controller or host machines. -

Big Sleep
A simple command line tool for text to image generation
A simple command line tool for text to image generation, using OpenAI's CLIP and a BigGAN. Ryan Murdock has done it again, combining OpenAI's CLIP and the generator from a BigGAN! This repository wraps up his work so it is easily accessible to anyone who owns a GPU. You will be able to have the GAN dream-up images using natural language with a one-line command in the terminal. User-made notebook with bug fixes and added features, like google drive integration. Images will be saved to wherever the command is invoked. If you have enough memory, you can also try using a bigger vision model released by OpenAI for improved generations. You can set the number of classes that you wish to restrict Big Sleep to use for the Big GAN with the --max-classes flag as follows (ex. 15 classes). This may lead to extra stability during training, at the cost of lost expressivity. -

Capslock
Tool to remap Caps Lock key behavior on Windows systems
Capslock is a command-line tool for analyzing the capabilities of Go packages to reveal what privileged operations their code and dependencies can perform. Rather than detecting vulnerabilities, Capslock focuses on identifying capabilities — permissions implied by calls to sensitive or privileged standard library functions, such as file system access, networking, or process control. By following transitive call graphs, it classifies which security-sensitive operations each package can reach, giving developers visibility into what their dependencies are capable of doing. This helps apply the Principle of Least Privilege to Go software, guiding audits, supply chain reviews, and trust assessments. Capslock aims to make security posture analysis more proactive by surfacing capability-based risk signals before malicious or overly powerful code is introduced into production. -

ClawHub
Skill Directory for OpenClaw
ClawHub is a public skill registry and ecosystem component for the OpenClaw AI assistant platform, designed to host, publish, version, and search text-based agent skill packages (each typically containing a SKILL.md plus metadata) that extend the capabilities of agents. As a centralized browsing and storage platform, ClawHub lets developers and contributors explore a catalog of reusable skills with supporting tags, changelogs, moderation controls, and vector search powered by embeddings instead of brittle keyword matching. Users can publish new skill versions, search for relevant abilities to add to their own OpenClaw agents, and view rendered skill documentation directly within the web interface or via a CLI-friendly API. It also supports a parallel “SOUL.md” registry for publishing narrative or lore content associated with skill collections, enabling richer context for skill authorship. -
