JetBrains released last month, the 2020 road map IntelliJ platform , now in another part of the 2020 plan, has released JetBrains IntelliJ IDE features based on the road map in 2020. The former is mainly concentrated in the low-level functions of the platform, while the latter focuses on higher-level features that will interact directly with the user.
localization
Last year, JetBrains website localized, offers eight different languages, and now, the team is based on IntelliJ IDE localized. It is currently being localized for the Asian market, IDE, and plans to provide initial support for Simplified Chinese, followed by Korean and Japanese. And it can provide translation capability in the form of plug-ins, so that the community will be able to provide translation in other languages.
The generic editor as IDE
With the possibility to improve the performance of recently launched, based on the IntelliJ IDE as a lightweight text editor to become more reasonable, so the development team is now building a special mode to edit non-project files. In this mode, the IDE will be more like a simple text editor, which will open at a faster rate, it does not store any configuration item, and it uses a conventional text editor same workflow to create, open and save the file.
Naturally, the feature set is also available in this mode will be very limited, however, if you need such as remodeling or debugging feature, you can easily switch to full project mode.
Staging Git Support
For Git integration feature requests, voice Git staging area is the highest. Git IntelliJ platform integration is built on an integrated version control and other (e.g. the Perforce and Subversion) the same frame, and it uses the concept of a list of changes rather than temporary storage area. Change list more flexible than the staging area, because they can manage multiple independent changes are not ready to commit. By recently added support for the change to move files between the portion of the list, basically it covers the main use cases temporary area.
计划在将来的 IDE 版本中为 Git 集成实现 Git 暂存区和变更列表两种不同的模式，开发者将能够基于变更列表选择使用当前 UI，还是使用支持暂存区但不支持变更列表的新 UI。
此外还有关于基于机器学习的自动补全、对于新手简化其环境配置问题、项目重构自动检测，以及 Code Vision 直接在代码编辑器中显示丰富的上下文信息等功能计划。
