3.0.0-1 (x64) Feb 25th, 2021. This is Ruby, a natural, flexible, object-oriented programming language created by the Japanese Yukihiro 'Matz' Matsumoto in 1993. Its author took parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) and used them to create something new.
- Ruby IDE’s I was initially thinking to create this categorized, both for Linux, Mac and Windows, but it so happens that most either support all of the operating systems, or just one. I was not able to find anymore to add to the list, and I checked out a dozen of ‘simple’ editors which don’t really account for being a full-scale IDE.
- Get the Toolbox App to download RubyMine and its future updates with ease. RubyMine is also available as a snap package. If you’re on Ubuntu 16.04 or later, you can install RubyMine from the command line. Sudo snap install rubymine -classic.

This extension provides enhanced Ruby language and debugging support for Visual Studio Code.
- Automatic Ruby environment detection with support for rvm, rbenv, chruby, and asdf
- Lint support via RuboCop, Standard, and Reek
- Format support via RuboCop, Standard, Rufo, Prettier and RubyFMT
- Semantic code folding support
- Semantic highlighting support
- Basic Intellisense support

By default, the extension provides sensible defaults for developers to get a better experience using Ruby in Visual Studio Code. However, these defaults do not include settings to enable features like formatting or linting. Given how dynamic Ruby projects can be (are you using rvm, rbenv, chruby, or asdf? Are your gems globally installed or via bundler? etc), the extension requires additional configuration for additional features to be available.
Using the Language Server
It is highly recommended that you enable the Ruby language server (via the Use Language Server setting or
ruby.useLanguageServer config option). The server does not default to enabled while it is under development but it provides a significantly better experience than the legacy extension functionality. See docs/language-server.md for more information on the language server.
Legacy functionality will most likely not receive additional improvements and will be fully removed when the extension hits v1.0
Example Initial Configuration:
Reviewing the linting, formatting, and environment detection docs is recommended
For full details on configuration options, please take a look at the
Ruby section in the VS Code settings UI. Each option is associated with a name and description.
docs/legacy.md contains the documentation around the legacy functionality

Choose the version of Ruby you want to install:
The first step is to install some dependencies for Ruby.
Next we're going to be installing Ruby using one of three methods. Each have their own benefits, most people prefer using rbenv these days, but if you're familiar with rvm you can follow those steps as well. I've included instructions for installing from source as well, but in general, you'll want to choose either rbenv or rvm.
Choose one method. Some of these conflict with each other, so choose the one that sounds the most interesting to you, or go with my suggestion, rbenv.
rbenv is a simple two step process. First you install
rbenv, and then
Arguably the least useful Ruby setup for development is installing from source, but I thought I'd give you the steps anyways:
The last step is to install Bundler
rbenv users need to run
rbenv rehash after installing bundler.

We'll be using Git for our version control system so we're going to set it up to match our Github account. If you don't already have a Github account, make sure to register. It will come in handy for the future.
Replace my name and email address in the following steps with the ones you used for your Github account.
The next step is to take the newly generated SSH key and add it to your Github account. You want to copy and paste the output of the following command and paste it here.
Once you've done this, you can check and see if it worked:
You should get a message like this:

And now, without further adieu:
If you're using rbenv, you'll need to run the following command to make the rails executable available:
Now that you've installed Rails, you can run the
rails -v command to make sure you have everything installed correctly:
If you get a different result for some reason, it means your environment may not be setup properly.
Setting Up MySQL
Rails ships with sqlite3 as the default database. Chances are you won't want to use it because it's stored as a simple file on disk. You'll probably want something more robust like MySQL or PostgreSQL.
There is a lot of documentation on both, so you can just pick one that seems like you'll be more comfortable with.
If you're new to Ruby on Rails or databases in general, I strongly recommend setting up PostgreSQL.
If you're coming from PHP, you may already be familiar with MySQL.
You can install MySQL server and client from the packages in the Ubuntu repository. As part of the installation process, you'll set the password for the root user. This information will go into your Rails app's
database.yml file in the future.
libmysqlclient-dev gives you the necessary files to compile the
mysql2 How to install free vpn in laptop. gem which is what Rails will use to connect to MySQL when you setup your Rails app.
When you're finished, you can skip to the Final Steps. Who has free installation on ovens.
Setting Up PostgreSQL
The easiest way to setup PostgreSQL is to install it on Windows using one of the Windows installers. You'll be able to run it in Windows and connect to it through Linux.
Download PostgreSQL for Windows and install it.
Pay attention to the username and password you setup during installation of Postgres as you will use this to configure your Rails applications later to login to Postgres when your Rails app runs.
You'll also need to install the development headers on Ubuntu so you can install the pg gem.
The best place to develop Rails apps on the Windows Subsystem for Linux is to navigate to `/mnt/c`. This is actually the C: drive on Windows and it lets you use Sublime, Atom, VS Code, etc on Windows to edit your Rails application.
And now for the moment of truth. Let's create your first Rails application:
You can now visit http://localhost:3000 to view your new website!
Now that you've got your machine setup, it's time to start building some Rails applications!
If you received an error that said
Access denied for user 'root'@'localhost' (using password: NO) then you need to update your config/database.yml file to match the database username and password.
To edit your code in Windows: open up Sublime, Atom, VS Code, or whatever editor your prefer and point them to your folders in
C:code and you'll be able to safely edit your Rails apps in Windows and run them in Linux!
When you create a new Rails app, you might run into the following error: parent directory is world writable but not sticky.
If you run into this issue, you can run
chmod +t -R ~/.bundle and that should fix the permissions errors and let you finish the bundle install for your Rails app.
