CodeRunner 4

Simplify the creation of your applications with the help of a lightning-fast code editor on your Mac. Write, run, and quickly debug code in a single application with outstanding support for more than 25 programming languages. Enhance your workflow by utilizing 230 syntax highlighters, essential IDE features, a documentation sidebar, fully personalizable settings, and dark/light appearance themes. The coderunner 4 app is a full-fledged alternative to any text editor, and on top of that, it is highly regarded by developers for its clean, minimalist interface and an entire suite of appealing and powerful features.

Write Smarter

Get your code up and running faster than ever before. CodeRunner 4 takes code completion, automatic indentation, and bracket matching to an entirely new level on your Mac. Its intelligent auto-complete function does not merely finish a line — it also suggests templates for writing an entire function from scratch. Quickly switch between tabs, drag and rearrange them in your preferred order, or hide them entirely when they are not needed for your current task.

Beautify Your Code

Leave your errors behind with the help of more than 230 syntax highlighters — all of them updated according to the latest language specifications and featuring fully customizable colors. Select a word or symbol, and with just a single keyboard shortcut you can instantly view and edit the local color scope. Watch as the active line becomes highlighted, and even the whitespace within it gets neatly organized. Toggle between dark and light themes, or choose a custom appearance to create exactly the look and feel you desire for your coding environment.

Fine-Tune Every Setting

Configure the way mac coderunner 4 works to match your exact preferences and habits. Don't like auto-closing brackets, indentation on new lines, or syntax highlighting? Simply switch them off in the preferences editor. Is auto-complete getting in the way of your custom-defined functions? Disable it temporarily while you are working on a particular section. You can even turn off auto-save during your experiments and exploratory sessions. Let CodeRunner work for you in every possible way.

Debug Like a Breeze

Produce consistently high-quality code by leveraging helpful and powerful debugging tools. For rapid debugging, use the built-in web inspector or add your own JavaScript and CSS with straightforward run modes. Toggle PHP output between the terminal and web mode for effortless side-by-side comparison. Set breakpoints, explore the call stack, inspect and edit variables on the fly, and step through your code in the blink of an eye — all within a single workspace.

Instant Document Search

Open online documentation for any programming language without ever leaving the application. The new informational sidebar in CodeRunner lets you look up functions, methods, classes, and other symbols right on the spot. You can even add your own custom documents as a search source, which allows you to spend far less time switching between different applications, while devoting more of your attention and energy to writing beautiful, well-structured code.

Use Any Language

CodeRunner speaks your language, so you can dive straight into your work without any obstacles or interruptions. Choose from more than 25 supported languages, including AppleScript, C, C++, C#, Go, Haskell, HTML/CSS, Java, JavaScript, Kotlin, LaTeX, Lua, Markdown, Node.js, Objective-C/C++, Perl, PHP, Python, Ruby, Rust, Shell Script, Swift, and TypeScript.
