News
What’s New in CLion?
CLion 2023.1 highlights:
- Debugger update:
- The ability to explore the underlying assembly code even when the source code is available (aka disassemble on demand).
- A reworked Attach to Process… dialog to make finding processes and attaching to them even easier and faster.
- Actions to suspend or resume individual threads, to help debug multi-threaded applications.
- Integration with vcpkg – CLion now assists with installing and updating vcpkg and its packages and browsing installed and available packages in the dedicated tool window. CLion helps with the missing dependencies by suggesting quick-fixes when you:
- Add #include for the header file from a package that is not yet installed.
- Use a package in a CMake script that is not yet installed.
- Clangd-based indexer (Experimental) – To speed up the Find Usages action and make it produce more accurate results in C++ code, a brand-new Clangd indexer has been introduced in CLion.
- New UI – The new UI has less visual clutter and shows the starting points for powerful features more concisely. In this release, the user experience of the new UI has been fine-tuned by redesigning the Run widget, adding an option to show hidden tabs and an option to split tool windows vertically, bringing a new Compact Mode for smaller screens and other changes.
