Supported languages

Development of a modern application involves using multiple languages, that is why RubyMine is an IDE for polyglot programming.

RubyMine supports the following languages:

Coding assistance in RubyMine includes:

• Syntax and error highlighting to maintain green code

• File templates to create stub classes, scripts, and so on

• Live templates to expand abbreviations into complicated code constructs

• Code completion to complete names of classes, methods, fields, parameters, and other entities depending on the context

• Code generation to generate language-specific code constructs

• Intention actions and quick fixes to optimize your code

• Code refactorings to rename, move, copy, and delete entities across the whole codebase

• Language injections for working with supported languages inside string literals, tags, or attributes

• Code reference information for viewing API documentation, parameter names and hints in methods, and so on

• Code folding to hide blocks of code that are not relevant to your current task

• Code formatting to format and arrange code according to your coding style

Besides coding assistance, RubyMine also supports language-specific tools for building, running, testing, and deploying applications.
