In the Ruby/Rails community, using a terminal is the most popular way to perform various commands and tasks. These tasks include running scripts, tests, Rails generators, Git and Docker commands, and many other things. We also noticed this ourselves when we did some RubyMine usability testing among developers at RailsConf 2019. We found that most participants ran Bundler commands and tests from the IDE terminal. In this blog post, we'll discuss the RubyMine features that can be used instead of running specific terminal commands and the benefits that working with the IDE provides. We’ve divide

To get the most recent information about Searching for usages in RubyMine, refer to the Search for usages topic. Find usages can be used to find all the pieces of code referencing a specific element, such as a class, method, symbol, or many of the others. RubyMine can also find dynamic usages, including Rails associations, factories, or delegates. You have the ability to specify the scope and search through an open file, project, referenced libraries, and so on. Find usages is very helpful for investigating a project and refactoring your code. For example, the Rename refactoring requires hi

To learn more about debugging capabilities available in RubyMine, refer to the help topics and tutorials from the Debug section. One of the main advantages of IDEs over text editors is the debugging experience. In this blog post, we’ll review the rich debugging capabilities available in RubyMine and then we’ll have a quick rundown of the new debugging features added in v2019.2. These include performance optimizations, Smart Step Into, block breakpoints, and others. The RubyMine debugger provides various ways to examine the state of a running application: you can step through your code and

YARD is a popular Ruby documentation generation tool that is used in multiple libraries for documenting code. RubyMine helps you to work with YARD tags and documentation in various ways, for example, you can view the documentation using Quick Documentation Lookup, create missing YARD tags, and check the validity of a YARD tag. RubyMine can also utilize the YARD annotations for better code insight, it uses them to help suggest more relevant results in code completion and parameter hints for methods. In this blog post, we’ll remind ourselves about the existing capabilities available in RubyMine

RubyMine provides you with loads of different useful features for working with source code: from basic code editing, smart navigation, and completion, all the way through to debugging remote applications. We always try to make features easy to use and discoverable, but sometimes it happens that our users still don’t know about some pretty handy capabilities. For example, when communicating with our users at conferences, we note that even the most grizzled veterans of RubyMine, that have been using it for years, sometimes don’t always know about some of the most basic navigation abilities that

To get the most recent information about Docker support in RubyMine, refer to our documentation: Tutorial: Docker Compose as a remote interpreter Tutorial: Docker as a remote interpreter RubyMine 2019.1 has a bunch of capabilities which allow you to work with Docker and Docker Compose. You can inspect existing images and containers, quickly edit Docker files using autocompletion, create new images and start services directly from the IDE, and run or debug your application using Docker SDK. Let’s take a look at how to do all this. Enable Docker support Work with images and containers

RubyMine 2019.1 adds support for rbspy – a great sampling profiler for Ruby (many thanks to @jvns!). This post will help you start profiling your Ruby/Rails apps with RubyMine in 5 minutes. Here are the exact steps: Identify the scenario to be analyzed Create a profiler configuration Run the program with the profiler attached Analyze the profiled data Export/Import the profiled data Other options First things first: make sure you have rbspy installed.

RubyMine has a number of Smart Keys – configurable options that help you avoid extra typing, and navigate through the code faster. Most of the smart keys, like auto-inserting closing brackets and quotes are on by default. However, there are other options you may want to enable. For instance, you may want to stop at parts of `CamelCase` and `snake_case` words when you navigate through the words in your code with ⌥+Arrows / Ctrl+Arrows. To quickly enable this option, invoke Find Action (⌘⇧A / Ctrl+Shift+A) and start typing “use camelhump words”. The IDE will match your query to the related

RubyMine comes with a testing suite for running RSpec, Minitest, Cucumber, and other tests based on your current context, and working with them in a friendly graphical user interface. Let’s see how it works in the following example. Run Tests Rerun Failed Tests Test Gutters Navigate to tests and back Run Tests Once your database and test environment are all set up, you can run all tests in your application, directory, or file, or even run any specific test. Simply navigate to the desired scope, and choose Run test(s)… from the context menu. Alternatively, use the keyboard shortcut Ct

RubyMine provides you with a set of intention actions that can help you to quickly fix code smells, convert statements for better code style, add strings to locale dictionaries, use language injections, and do other handy things simply by pressing Alt+Enter. Let's review all the basic and new intention actions added in RubyMine 2018.3. Quick Overview New intentions in RubyMine Quick Overview Let's start with some basic examples: Below is a two-line statement that uses a ternary operator.
