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. -

Angular ESLint
Monorepo for all the tooling related to using ESLint with Angular
Monorepo for all the tooling which enables ESLint to lint Angular projects. Follow the latest Getting Started guide on angular.io in order to install the Angular CLI. Create a new Angular CLI workspace in the normal way, optionally using any of the supported command line arguments and following the interactive prompts. As well as installing all relevant dependencies, the ng add command will automatically detect that you have a workspace with a single project in it, which does not have a linter configured yet. It can therefore go ahead and wire everything up for you! -

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. -

ShellCheck
A static analysis tool for shell scripts
ShellCheck is a GPLv3 tool that provides warnings and possible suggestions for bash/sh shell scripts. ShellCheck finds bugs in your shell scripts. You can cabal, apt, dnf, pkg or brew install it locally right now. ShellCheck highlights and clarifies typical beginner's syntax mistakes and issues that cause a shell to give a cryptic error message. It shows typical intermediate level semantic problems that cause a shell to behave in a abnormally and counter-intuitively. It can also discover ssubtle caveats, corner cases and pitfalls that may cause an user's working script to fail under probable future circumstances. ShellCheck.net is always synchronized to the latest git version, and is the simplest way to give ShellCheck a go. -

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. -

PHP dotenv
Loads environment variables automatically
You should never store sensitive credentials in your code. Storing configuration in the environment is one of the tenets of a twelve-factor app. Anything that is likely to change between deployment environments, such as database credentials or credentials for 3rd party services, should be extracted from the code into environment variables. Basically, a .env file is an easy way to load custom configuration variables that your application needs without having to modify .htaccess files or Apache/nginx virtual hosts. This means you won't have to edit any files outside the project, and all the environment variables are always set no matter how you run your project, Apache, Nginx, CLI, and even PHP's built-in webserver. It's WAY easier than all the other ways you know of to set environment variables, and you're going to love it! -

Semgrep
Lightweight static analysis for many languages
Static analysis at ludicrous speed. Find bugs and enforce code standards. Find and prevent security issues in Terraform, Docker, Kubernetes, nginx, and AWS configs before they go into production. Go beyond application code and protect the entire stack with a breadth of scanning capabilities. Don't leak secrets, scan every commit and ensure secrets don't make it to production. 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. -
23
Deptrac
Keep your architecture clean.
Deptrac is a static analysis tool for PHP that helps maintain architectural boundaries within codebases.

Pulumi
Developer-first infrastructure as code. Your cloud, your language
Pulumi's Infrastructure as Code SDK is the easiest way to create and deploy cloud software that use containers, serverless functions, hosted services, and infrastructure, on any cloud. Simply write code in your favorite language and Pulumi automatically provisions and manages your AWS, Azure, Google Cloud Platform, and/or Kubernetes resources, using an infrastructure-as-code approach. Skip the YAML, and use standard language features like loops, functions, classes, and package management that you already know and love. Pulumi is open source under the Apache 2.0 license, supports many languages and clouds, and is easy to extend. This repo contains the pulumi CLI, language SDKs, and core Pulumi engine, and individual libraries are in their own repos. Walk through end-to-end workflows for creating containers, serverless functions, and other cloud services and infrastructure. -

Pylint
It's not just a linter that annoys you!
Pylint is a static code analyzer for Python 2 or 3. The latest version supports Python 3.7.2 and above. Pylint analyses your code without actually running it. It checks for errors, enforces a coding standard, looks for code smells, and can make suggestions about how the code could be refactored. Projects that you might want to use alongside pylint include flake8 (faster and simpler checks with very few false positives), mypy, pyright or pyre (typing checks), bandit (security-oriented checks), black and isort (auto-formatting), autoflake (automated removal of unused import or variable), pyupgrade (automated upgrade to newer python syntax) and pydocstringformatter (automated pep257). Pylint isn't smarter than you: it may warn you about things that you have conscientiously done or checks for some things that you don't care about. During adoption, especially in a legacy project where pylint was never enforced.
