Install

Press F1, type ext install then search for ruby.

Gem Dependencies

Depending on your setup, you may need to manually install gem dependencies like rubocop, ruby-debug-ide or solargraph. This can be complicated because there are many different ways to use Ruby itself - system ruby, rbenv, chruby, rvm, bundler, etc. Your results may also vary depending on how you start VS Code and the environment variables present at that time.

The important thing is that if VS Code can't find rubocop, our extension can't either. One way to debug these problems is to investigate within VS Code's Integrated Terminal. (View > Integrated Terminal). Try ruby -v, gem env gemdir, gem list | grep rubocop, which rubocop and then rubocop -v. This might shed some light on why a gem dependency isn't working.

Language Server

As of version v0.20.0, a new language server has been introduced into the extension. This server provides the following features:

• Balanced pairs (eg def-end, if-end, etc) highlighting
• Syntax aware code folding

The server is designed to slowly replace existing extension functionality. Users can choose to replace that functionality with that of the language server's via the useLanguageServer configuration option (set it to true). You can verify the server is running via the "Output" tab in VSCode (next to the Terminal).

Feature Requests

The language server is under active development. You can check Issue 317 to see the currently proposed feature list. Please do not open GitHub issues for unimplemented features that are already on that list!

Debugger

Install Ruby Dependencies

In this extension, we implement ruby debug ide protocol to allow VS Code to communicate with ruby debug, it requires ruby-debug-ide to be installed on your machine. This is also how RubyMine/NetBeans does by default.

• If you are using JRuby or Ruby v1.8.x (jruby, ruby_18, mingw_18), run gem install ruby-debug-ide.
• If you are using Ruby v1.9.x (ruby_19, mingw_19), run gem install ruby-debug-ide. Make sure ruby-debug-base19x is installed together with ruby-debug-ide.
• If you are using Ruby v2.x
  • gem install ruby-debug-ide
  • gem install debase (or gem install byebug)

Add VS Code config to your project

Go to the debugger view of VS Code and hit the gear icon. Choose Ruby or Ruby Debugger from the prompt window, then you'll get the sample launch config in .vscode/launch.json. The sample launch configurations include debuggers for RSpec (complete, and active spec file) and Cucumber runs. These examples expect that bundle install --binstubs has been called.

Detailed instruction for debugging Ruby Scripts/Rails/etc

Debugger F.A.Q.

Conditional breakpoint doesn't work

You need use Ruby 2.0 or above and you need to update debase to latest beta version gem install debase -v 0.2.2.beta10.

Linters

Available Linter hooks

You will need to install the ruby gem for each of these for linting to work (except ruby -wc of course)

• ruby -wc
• rubocop
• ruby-lint
• reek
• fasterer
• debride

Enable each one in your workspace or user settings:

// Basic settings: turn linter(s) on
"ruby.lint": {
	"reek": true,
	"rubocop": true,
	"ruby": true, //Runs ruby -wc
	"fasterer": true,
	"debride": true,
	"ruby-lint": true
},

// Time (ms) to wait after keypress before running enabled linters. Ensures
// linters are only run when typing has finished and not for every keypress
"ruby.lintDebounceTime": 500,

//advanced: set command line options for some linters:
"ruby.lint": {
	"ruby": {
		"unicode": true //Runs ruby -wc -Ku
	},
	"rubocop": {
		"only": ["SpaceInsideBlockBraces", "LeadingCommentSpace"],
		"lint": true,
		"rails": true
	},
	"reek": true
}

By default no linters are turned on.

Each linter runs only on the newly opened or edited file. This excludes some of the linters functionality, and makes some overly chatty - such as ruby-lint reporting undefined methods. The usual configuration file for each linter will be use as they would be when running from the command line, however settings that include/exclude files will not likely be followed.

Relevant configuration files:

• debride: none
• ruby: none
• reek: *.reek
• fasterer: .fasterer.yml
• ruby-lint: ruby-lint.yml
• rubocop: .rubocop.yml

Settings available (in your VSCode workspace) for each of the linters:

"debride": {
	"rails": true //Add some rails call conversions.
}

"ruby"//no settings
"reek" //no settings
"fasterer" //no settings

"ruby-lint": {
	"levels": [/* a subset of these */ "error","warning","info"],
	"classes":[ /* a subset of these */ "argument_amount", "loop_keywords", "pedantics", "shadowing_variables", "undefined_methods", "undefined_variables", "unused_variables", "useless_equality_checks" ]
}

"rubocop": {
	"lint": true, //enable all lint cops.
	"only": [/* array: Run only the specified cop(s) and/or cops in the specified departments. */],
	"except": [/* array: Run all cops enabled by configuration except the specified cop(s) and/or departments. */],
	"forceExclusion": true, //Add --force-exclusion option
	"require": [/* array: Require Ruby files. */],
	"rails": true //Run extra rails cops
}

Formatting

The VS Code Ruby extension can automatically format your Ruby files whenever you save.

Rubocop

Set ruby.format to rubocop to enable rubocop formatting on save.

Formatting requires the rubocop gem to be installed. Note that you may have to turn on some of the AutoCorrect functions in your .rubocop.yml file. See the rubocop documentation.

Important note: VS Code has a timeout that limits file formatters to 750ms. This is often not enough time for rubocop to complete. In the near future VS Code will allow customizing this timeout via the editor.formatOnSaveTimeout setting. See #43702 for more details.

Rufo

Rufo is an alternative Ruby formatting tool. See the VS Code Rufo Extension if you want to try it.

Autocomplete

The ruby.codeCompletion setting lets you select a method for code completion and other intellisense features. Valid options are rcodetools and false.

rcodetools

To enable method completion in Ruby, run gem install rcodetools. You may need to restart Visual Studio Code the first time.

[1, 2, 3].e #<= Press CTRL-Space here

Solargraph

Solargraph is an alternative Ruby code completion tool. See the Solargraph extension if you want to try it.

For more information about using Solargraph, refer to the Solargraph extension.

Intellisense (Go to/Peek Definition/Symbols)

Use the ruby.intellisense setting to select a go to/peek definition/symbol method. Valid options are rubyLocate, and false.

rubyLocate

The rubyLocate option includes workspace parsing functionality. It allows VS Code to go to definition, peak definition and provides symbols for modules, classes, and methods defined within the same workspace. You can set glob patterns to match including and excluding particular files. The exclude match also runs against directories on initial load, to reduce latency. rubyLocate uses ruby-method-locate to parse symbols.

The default settings are:

"ruby.locate": {
	"include": "**/*.rb",
	"exclude": "{**/@(test|spec|tmp|.*),**/@(test|spec|tmp|.*)/**,**/*_spec.rb}"
}

The defaults will include all files with the rb extension, but avoids searching within the test, spec, tmp directories, as well as any directories begining with a ., AND any files ending with _spec.rb.

If you change these settings, currently you will need to reload your workspace.

We now provide go to definition within erb files, as well as syntax highlighting for erb.

Solargraph

Solargraph now includes go to/peek definition and other language features. See the Solargraph extension for more information.

When using Solargraph it is recommended to set ruby.intellisense to false.

Contributing

Feel free to open issues or PRs! We welcome all contributions, even from beginners. If you want to get started with a PR, please do the following:

1. Check out the VS Code Extension Docs, especially Running and Debugging Extensions.
2. Fork this repo.
3. Install dependencies with npm install. You'll also need to install dependencies in the client and server directories.
4. Run npm run watch in a shell to get the Typescript compiler running.
5. Run npm run watch:client to compile the client and npm run watch:server to compile the server. You'll need all three running to do development on the extension.
6. Open the repo directory in VS Code.
7. Make a code change and test it. You can use the Debug tab and the Launch Extension configuration to help.
8. Create a branch and submit a PR!
