IntelliJ IDEA 2020.3 – Java IDE for Linux Ubuntu
IntelliJ IDEA 2020.3 adds interactive hints and inline watches in the debugger, improves support for Java 15, and introduces support for Git staging, along with a variety of other features. Below are some of the most exciting features released with this update:
- New Welcome screen: The IntelliJ IDEA welcome screen has been redesigned. The Initial wizard has been replaced with a quick-access screen containing four tabs: Projects for managing your projects, Customize for setting up the IDE interface, Plugins for plugin installation, and Learn IntelliJ IDEA for access to help and learning resources.
- IDE theme synced with OS settings: IntelliJ IDEA can now synchronize its theme with your OS theme. To enable this feature, go to Settings / Preferences | Appearance & Behavior | Appearance and tick the Sync with OS checkbox. Click the gear icon next to Sync with OS to select your preferred theme.
- Reader mode: Read-only files and files from external libraries are now opened by default in Reader mode. In this mode, comments look like formatted text and font ligatures are enabled to help make the code more readable to users. You can customize Reader mode settings in Settings / Preferences | Editor | Reader Mode.
- LightEdit improvements: In IntelliJ IDEA 2020.3 we’ve improved the UX for LightEdit mode. To open files in LightEdit mode from the command line, you now type -e (–edit) followed by the name of the file you want to open, or omit the filename to reopen your previous session. A new status bar in the LightEdit window provides access to the full set of IDE features. If you want to learn more about LightEdit mode updates, read this blog post.
- Preview tab: You can now open a file in a preview tab with a single click. When you open a file in a preview tab, its name is displayed in italic. If you start editing this file, it will cease to be a preview and will become an ordinary file. If you single-click another file to open it in preview mode, it will appear in the same tab, replacing the previously opened one. To enable this feature, click the gear icon in the Project view and select Enable Preview Tab.
- Linux emoji picker: In v2020.3, we’ve added an emoji picker for Linux. To open the emoji picker, press Ctrl+Alt+; . You can filter emojis by category, change their skin tone, and search for emoji by name. The emoji picker fully supports keyboard navigation.
- Update JDK from inside the IDE: Starting from v2020.3, it is possible to migrate to the latest JDK from a popup that appears whenever an update is available. You can choose whether you want to install it or skip it.
- Improved Markdown editing and preview: The Markdown tool now has a better preview UI and improved UX. You can customize Markdown format in Settings / Preferences | Editor | Code Style | Markdown. Press ⌘+Alt+L on Mac or Ctrl+Alt+L on Windows or Linux to apply formatting. The Auto-Scroll Preview button in the top-right corner of the editor allows you to sync scrolling of the preview pane and the editor. They’ve also added support for Mermaid.js.
- Git stage support: You can now stage changes directly from your IDE. To enable this feature, go to Settings / Preferences | Version Control | Git and tick the Enable staging area checkbox. Click the + icon to add your files to the new Staged node in the Commit view. You can also stage changes right from the gutter or in the Diff view.
- Store and share run/debug configuration templates: In IntelliJ IDEA 2020.3, you can store run configuration templates as XML files and then share them with teammates via Git or another VCS. To enable the features, go to Edit Configurations …, expand the Templates node, select a configuration template, select the Store as project file checkbox, and define a path for storing this configuration template.
