Description
The IRB shipped with Ruby 3.1 provides a dialog window feature on the terminal to achieve autocomplete. This is implemented as a new feature in Reline, which displays a dialog in an interactive user input interface at any time you want. In this article, I will show you how to utilize this dialog display feature of Reline, with IRB and the Ruby debugger which is a new feature in Ruby 3.1.

In this presentation titled "Graphical Terminal User Interface of Ruby 3.1," ITOYANAGI Sakura discusses the new features in the Interactive Ruby (IRB) that accompany Ruby version 3.1, particularly focusing on the dialog window feature implemented through Reline. The presentation is part of the RubyKaigi Takeout 2021 event, where Sakura shares insights regarding their experiences in developing the new features while balancing personal tasks such as climbing and hiking. Here are the key points covered in the video: - **Introduction to Reline and IRB**: The IRB (Interactive Ruby) has seen several improvements aimed at enhancing user experience through better functionality. The speaker emphasizes that Reline, a terminal control software they built from scratch, serves as the foundation for these advancements. - **Dialog Window Feature**: Sakura introduces the new dialog window feature in IRB, likening it to interfaces found in Integrated Development Environments (IDEs). This feature allows users to see context-related information and options displayed by the cursor in a user-friendly manner. - **User Interactivity**: The dialog window can be navigated with keystrokes, and it includes options for defining its dimensions and enabling scrollbars. Users can benefit from auto-completion capabilities without needing additional complex setups. - **Document Viewing Improvements**: A significant enhancement in the new IRB is the ability to display documentation along with autocomplete options. The speaker notes that accessibility has been improved, making it easier for users to access relevant documentation without needing additional instructions. - **Community Support and Contributions**: ITOYANAGI expresses a desire for collaboration in maintaining Reline and mentions that contributions would be valued through GitHub Sponsors. They highlight the need for individuals who have a strong commitment to the Ruby ecosystem. ### Conclusions These improvements reflect ongoing efforts to enhance the Ruby programming experience, combating historical issues regarding the accessibility of documentation and tools for developers. The speaker reinforces the message that the best user interfaces are intuitive and require minimal explanation, showcasing the advancements made with IRB 3.1 in line with this principle.
