Iosevka
Versatile typeface for code, from code
Iosevka is an open-source, sans-serif + slab-serif, monospace + quasi‑proportional typeface family, designed for writing code, using in terminals, and preparing technical documents. The Iosevka’s monospace family is provided in a slender outfit by default: glyphs are exactly 1/2em wide. Compared to the competitors, you could fit more columns within the same screen width. Iosevka provides two widths, Normal and Extended. If you prefer more breeze between the character, choose Extended and enjoy. Terminal emulators have a stricter compatibility requirements for fonts. Therefore, Iosevka and Iosevka Slab all contain two specialized families, Term and Fixed, targeting terminal users. In these families, the symbols will be narrower to follow terminals’ ideology of column count. In the Fixed families, the ligation will be disabled to ensure better compatibility in certain environments. -

Blockly
The web-based visual programming editor
The Blockly library adds an editor to your app that represents coding concepts as interlocking blocks. It outputs syntactically correct code in the programming language of your choice. Custom blocks may be created to connect to your own application. Blockly in a browser allows web pages to include a visual code editor for any of Blockly's five supported programming languages, or your own. Blockly plugins are self-contained pieces of code that add functionality to Blockly. Blockly codelabs provide step-by-step instructions on how to use and customize Blockly. From a user's perspective, Blockly is an intuitive, visual way to build code. From a developer's perspective, Blockly is a ready-made UI for creating a visual language that emits syntactically correct user-generated code. Blockly can export blocks to many programming languages. -

Protect the privileged CI/CD environment from malicious activity that could result in access to source code, secrets, and more. Run with registry rules or your own. Code is analyzed locally (not uploaded). Get results at ludicrous speed with diff-aware scans, review findings in MR and PR comments, and deploy Semgrep across your organization’s projects. Go beyond the registry with rules specific to your organization. Write rules to enforce your own code guardrails. -

Static Analysis Tools for PHP
Docker image that provides static analysis tools for PHP
Docker image providing static analysis tools for PHP. The list of available tools and the installer is actually managed in the jakzal/toolbox repository. Docker image with quality analysis tools for PHP. To run the selected tool inside the container, you'll need to mount the project directory on the container with -v "$(pwd):/project". Some tools like to write to the /tmp directory (like PHPStan, or Behat in some cases), therefore it's often useful to share it between docker runs, i.e. with -v "$(pwd)/tmp-phpqa:/tmp". If you want to be able to interrupt the selected tool if it takes too much time to complete, you can use the --init option. Some tools are not included in the docker image, to use them refer to their documentation. Provides utilities to report legacy tests and usage of deprecated code. -

eslint-plugin-testing-library
ESLint plugin to follow best practices and anticipate common mistakes
ESLint plugin to follow best practices and anticipate common mistakes when writing tests with Testing Library. You can find detailed guides for migrating eslint-plugin-testing-library in the migration guide docs. Add testing-library to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix. With the default setup mentioned before, eslint-plugin-testing-library will be run against your whole codebase. You can run this plugin only against your tests files. One way of restricting ESLint config by file patterns is by using ESLint overrides. Another approach for customizing ESLint config by paths is through ESLint Cascading and Hierarchy. This is useful if all your tests are placed under the same folder, so you can place there another .eslintrc where you enable eslint-plugin-testing-library for applying it only to the files under such folder, rather than enabling it on your global .eslintrc which would apply to your whole project. -

Flow
A static type checker for JavaScript
Flow is a static type checker for JavaScript. It was designed to help improve code quality and developer productivity. It does this through several smart capabilities. First, it identifies problems as you code, so you no longer have to waste time guessing and checking again and again. Second, it understands your code and makes its knowledge available, allowing you to build other smart tools on top of it. Third, it helps you refactor safely so you can focus on the changes you want to make and not on what you might break. Lastly, it can help prevent bad rebases and protect your carefully designed library, which is especially relevant when working with a large group of developers. Flow integrates with many tools, so you can easily and seamlessly insert it into your existing workflow and toolchain. -

GrumPHP
A PHP code-quality tool
Sick and tired of defending code quality over and over again? GrumPHP will do it for you! This composer plugin will register some git hooks in your package repository. When somebody commits changes, GrumPHP will run some tests on the committed code. If the tests fail, you won't be able to commit your changes. This handy tool will not only improve your codebase, it will also teach your co-workers to write better code following the best practices you've determined as a team. GrumPHP has a set of common tasks built in. You will be able to use GrumPHP with a minimum of configuration. We don't want to bore you with all the details, so quick: install it yourself and unleash the power of GrumPHP! -

MoarVM
A runtime built for the 6model object system
Short for "Metamodel On A Runtime", MoarVM is a modern virtual machine built for the Rakudo Perl 6 compiler and the NQP Compiler Toolchain. MoarVM is used by the majority of Perl 6 programmers. Highlights include: Great Unicode support, with strings represented at grapheme level, dynamic analysis of running code to identify hot functions and loops, and perform a range of optimizations, including type specialization and inlining, support for threads, a range of concurrency control constructs, and asynchronous sockets, timers, processes, and more, generational, parallel, garbage collection, support for numerous language features, including first class functions, exceptions, continuations, runtime loading of code, big integers and interfacing with native libraries. MoarVM provides very little directly - and that's a good thing. It is not tied to a particular way of doing inheritance, roles, mixins, method resolution, type-checking, and so forth. -
23
eslint-plugin-jsx-a11y
Static AST checker for a11y rules on JSX elements
Static AST checker for accessibility rules on JSX elements. This plugin does a static evaluation of the JSX to spot accessibility issues in React apps. Because it only catches errors in static code, use it in combination with axe-core/react to test the accessibility of the rendered DOM. Consider these tools just as one step of a larger a11y testing process and always test your apps with assistive technology. If you installed ESLint globally (using the -g flag in npm, or the global prefix in yarn) then you must also install eslint-plugin-jsx-a11y globally. To enable your custom components to be checked as DOM elements, you can set global settings in your configuration file by mapping each custom component name to a DOM element type. Enforce all elements that require alternative text have meaningful information to relay back to the end user. -

BAT
A cat(1) clone with syntax highlighting and Git integration
A cat(1) clone with syntax highlighting and Git integration. By default, bat pipes its own output to a pager (e.g. less) if the output is too large for one screen. If you would rather bat work like cat all the time (never page output), you can set --paging=never as an option, either on the command line or in your configuration file. If you intend to alias cat to bat in your shell configuration, you can use alias cat='bat --paging=never' to preserve the default behavior. Even with a pager set, you can still use bat to concatenate files. Whenever bat detects a non-interactive terminal (i.e. when you pipe into another process or into a file), bat will act as a drop-in replacement for cat and fall back to printing the plain file contents, regardless of the --pager option's value. Use bat --list-themes to get a list of all available themes for syntax highlighting.
