For example, it will auto-continue comment lines and auto-close end tokens, pipes, or string interpolation curly braces. The Ruby LSP extension also provides some convenient completions using format on type. To do that, you must enable format on save. You can also run the formatter on each save ( Editor: Format On Save) to keep your Ruby code properly formatted automatically while you are working. If your project does not use RuboCop, the Ruby LSP will format files using SyntaxTree. You can format your Ruby file using ⇧⌥F (Windows Shift+Alt+F, Linux Ctrl+Shift+I) or by running the Format Document command from the Command Palette ( ⇧⌘P (Windows, Linux Ctrl+Shift+P)) or the context menu in the editor. '' : true, Linting and formattingīy default, Ruby LSP provides linting and formatting through an integration with RuboCop. To use this feature, the editor must have semantic highlighting enabled. Themes must use the information surfaced by the Ruby LSP in order to provide rich highlighting for Ruby files.

Note: This screenshot is using the Spinel theme included in the Ruby extension pack.

Local arguments (such as method, block or lambda arguments) consistently inside the scope in which they exist.Method invocations consistently, without confusing it with local variables.Ruby LSP is able to use semantic syntax highlighting and styling due to its rich understanding of a project source code. To see the full list, check out the snippets file in the Ruby LSP GitHub repository. While inlay hints can be helpful for understanding your code, you can also disable the feature via the Editor > Inlay Hints: Enabled setting ( ) or use the following to disable this feature only for Ruby LSP: 'rubyLsp.enabledFeatures' : Code snippetsĪs you type in a Ruby file, Ruby LSP might suggest expanding snippets used for common Ruby operations such as creating a new method, class, block, or test boilerplate. In the example below, you can see StandardError being shown as the implicit exception class being rescued in an empty rescue call. Ruby LSP is able to display useful information about inferred or implicit values in your code. To learn more about moving quickly through your source code with VS Code, check out Code Navigation. Ruby LSP parses source code and provides symbol detection and navigation for the Outline pane, file breadcrumbs, and symbol searches (accessible with ⇧⌘O (Windows, Linux Ctrl+Shift+O) by default). If you have any problems, see troubleshooting for next steps. The extension will automatically try to update the ruby-lsp language server gem once per day if you want to force that to happen, use the Command Palette ( ⇧⌘P (Windows, Linux Ctrl+Shift+P)) to execute Ruby LSP: Update language server gem. If you want to customize that behavior, set the following configuration in your user settings: 'byVersionManager' : 'rbenv' No configuration should be required.īy default, the extension tries to automatically detect the Ruby version manager you're using and use the right versions and paths accordingly. ruby-lsp folder automatically with a custom bundle that includes the language server gem ruby-lsp. The server status should display starting or running, but not error. If the version manager has been configured, it should display the right Ruby version for your project. Check your installationĪfter installing, check the language status item to see the status of the Ruby LSP server. We'll discuss many of Ruby LSP features in this topic but you can also refer to the extension's documentation at. ( ⇧⌘X (Windows, Linux Ctrl+Shift+X)) and searching for 'Ruby LSP'. You can find and install the Ruby LSP extension from within VS Code via the Extensions view Install the Ruby LSP extension in VS Code Note: As with installing any new toolset on your machine, you'll want to make sure to restart your terminal/Command Prompt and VS Code instances to use the updated toolset location in your platform's PATH variable. Follow the installation guidance for your platform. While Ruby is installed by default on some operating systems (such as macOS and some distributions of Linux), we recommend using a version manager such as rbenv to be able to access newer versions of Ruby on Windows, macOS, and Linux. Installation Install Ruby through a version manager This topic goes into detail about setting up and using Ruby within Visual Studio Code, with the It is often used for web development with a range of different frameworks, and for scripting, allowing for fast iterations when building prototypes. With an expressive and elegant syntax, part of the Ruby philosophy is to make developers happy. Ruby is a dynamic, open-source programming language known for its simplicity and productivity.
