About
            Crystal’s syntax is heavily inspired by Ruby’s, so it feels natural to read and easy to write, and has the added benefit of a lower learning curve for experienced Ruby devs. Crystal is statically type-checked, so any type errors will be caught early by the compiler rather than fail on runtime. Moreover, and to keep the language clean, Crystal has built-in type inference, so most type annotations are unneeded. All types are non-nilable in Crystal, and available variables are represented as a union between the type and nil. As a consequence, the compiler will automatically check for null references in compile time. Crystal’s answer to metaprogramming is a powerful macro system, which ranges from basic templating and AST inspection to types inspection and running arbitrary external programs.

            The core of extensible programming is defining functions. Python allows mandatory and optional arguments, keyword arguments, and even arbitrary argument lists. Whether you're new to programming or an experienced developer, it's easy to learn and use Python. Python can be easy to pick up whether you're a first-time programmer or you're experienced with other languages. The following pages are a useful first step to get on your way to writing programs with Python! The community hosts conferences and meetups to collaborate on code, and much more. Python's documentation will help you along the way, and the mailing lists will keep you in touch. The Python Package Index (PyPI) hosts thousands of third-party modules for Python. Both Python's standard library and the community-contributed modules allow for endless possibilities.

            Test Mace is a modern powerful crossplatform tool for working with an API and creating automated API tests. Create requests and scenarios using variables, authentication, autocomplete feature and syntax highlighting. Build complex scenarios using our convenient and simple UI interface. Perform full regression testing with just one click. Assign a request result to a variable and get access from other nodes. Save authorization tokens, response headers or parts of a response body. Run your scenarios in different environment contexts. Use this to organize development, stage and production environments. Embedded authentication methods will help you to do authentication if you use one of the most popular types. You can use quick share feature to share your request with colleagues. Just press a button to copy a specific node's url. All that you need now is to send this url to your teammate.

            Zig is a general-purpose programming language and toolchain for maintaining robust, optimal and reusable software.
Focus on debugging your application rather than debugging your programming language knowledge.
A fresh approach to metaprogramming based on compile-time code execution and lazy evaluation.
No hidden control flow.
No hidden memory allocations.
No preprocessor, no macros.
Call any function at compile-time.
Manipulate types as values without runtime overhead.
Comptime emulates the target architecture.
Use Zig as a zero-dependency, drop-in C/C++ compiler that supports cross-compilation out-of-the-box.
Leverage zig build to create a consistent development environment across all platforms.
Add a Zig compilation unit to C/C++ projects; cross-language LTO is enabled by default.
