CodeRunner 4 - Perpetual License

CodeRunner is a lightweight code editor and IDE for macOS developed by Nikolai Krill: a native app that opens a file in almost any programming language, runs it with one click and shows the output in a built-in console. It suits developers, students and anyone who writes scripts on a Mac and wants a tool that starts instantly and stays simple, without setting up a full development environment. This listing is a license key for the full version of CodeRunner 4: the key removes the trial limit of the copy downloaded from the developer's website, and the developer includes future updates with every license.

This product is a perpetual license key for CodeRunner 4: it does not expire and can be used on 1 Mac running macOS. The key is delivered by email together with the activation instructions.

A typical session starts with a new document, the language picked in the toolbar and Run: output, process statistics and errors appear right below the code, while the documentation sidebar explains a function without leaving the window.

Key Features:

• Run code in 25 languages: Python, JavaScript, Node.js, Swift, C, C++, Objective-C, Java, Go, Rust, PHP, Ruby, Perl, Lua, shell scripts, HTML/CSS and more run from the toolbar with arguments and input sets; other languages are added with their terminal command.
• Code completion: Fuzzy matching finds the right symbol among thousands of candidates, completes whole expressions rather than single words and shows documentation snippets and placeholders you fill in with the Tab key.
• Debugger with breakpoints: A click in the margin sets a breakpoint; when it is hit you step through the code, inspect the call stack, edit variables and type into the debug console. Works in more than a dozen languages via lldb, pdb, jdb, Xdebug and node.
• Live errors and linting: Syntax errors and common mistakes are underlined as you type, compile and runtime messages from the console are linked to the line that caused them, and a third-party linter is added with its terminal command.
• Editor and navigation: Multiple selections, smart auto-indent, tokenizers that recognise local symbols (with renaming), regex find and replace across folders, Vim mode, custom key bindings, file and symbol navigators, 200+ TextMate syntax modes and a web inspector.
