#This extension is now actively developed under rubyide

This extension provides rich Ruby language and debugging support for Visual Studio Code. Fully tested against *nix/Windows and Ruby 1.9.3 to 2.2.0. It's still in progress ( GitHub ), please expect frequent updates with breaking changes before 1.0. If you are interested in this project, feel free to

• Subscribe to our mailing list, get notified when we release new features or fix bugs.
• File GitHub issues anytime you ran into unexpected situations/bugs.
• Fork our project, hack it around and send us PRs!

Press F1, type ext install ruby.

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)
  • gem install ruby-debug-ide, the latest version is 0.6.0. Make sure ruby-debug-base is installed together with ruby-debug-ide`.
• If you are using Ruby v1.9.x (ruby_19, mingw_19)
  • gem install ruby-debug-ide, the latest version is 0.6.0. Make sure ruby-debug-base19x is installed together with ruby-debug-ide.
• If you are using Ruby v2.0.x
  • gem install ruby-debug-ide -v 0.4.32 or higher versions
  • gem install debase -v 0.2.1 or higher versions

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

{
	"version": "0.2.0",
	"configurations": [
		{
			"name": "Debug Local File",

}

Read following instructions about how to debug ruby/rails/etc locally or remotely

• Debug Ruby Scripts
• Debug Rails App
• Attach to process

You will need to install the ruby gem for eacy 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
}

//advanced: set command line options for some linters:
"ruby.lint": {
	"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. */],
	"require": [/* array: Require Ruby files. */],
	"rails": true //Run extra rails cops
