Code Completion

Advanced Code Completion

Any programmer knows the importance of good code completion. That's why CodeRunner supports full-blown IDE-level code completion for most languages, including fuzzy-search, tab-selectable placeholders, and documentation snippets.

Languages

Run Code in Any Language

CodeRunner was built on the principle that you should be able to run your code instantly in any language. CodeRunner can run code in 23 languages out-of-the-box, and can be easily extended to support any other language. Adding a language is as easy as entering its terminal command.

CodeRunner can also run multi-file projects without any manual setup required.

Debugging

Debugging with Breakpoints

It's easy to get frustrated when your code is not working right. New in CodeRunner 2.2, you can set breakpoints and step through code line by line.

Just click the text margin to set a breakpoint and start debugging. Explore the call stack, view and edit local variables, and leverage the full power of the debugger by issuing debugger commands.

Debugging your code has never been this convenient.

Templates

Code Templates

Quickly get down to coding without the need to write main functions, class definitions or other boilerplate code.

CodeRunner includes a number of fully-customizable templates for each language, to easily create classes, scripts, main methods, and the like. This also makes it easy to create multi-file projects.
