CLion 2018.1 EAP: Valgrind on WSL, partial commits in Git and C++ support improvements


The new CLion 2018.1 EAP (build 181.3870.21) is now available for download. Get it now from our site or wait for a patch update right in the IDE (if you are using previous EAP build).

Valgrind on WSL

Valgrind Memcheck was integrated into CLion in v2017.3 and gave Linux and macOS user ability to catch memory errors and leaks right from the IDE. Unfortunately, Windows users are lacking Valgrind. But since WSL is here and supported in CLion, we’ve enabled Valgrind on WSL!

When you have WSL toolchains configured in CLion, you can now see the Valgrind settings in Settings | Build, Execution, Deployment. Install Valgrind on your WSL instance (sudo apt-get install valgrind) and provide a path to the Valgrind executable in Valgrind settings in CLion. Now you can select a Run/Debug configuration and run it under Valgrind memcheck via the Run | Run Valgrind Memcheck… or special icon in the Navigation bar located next to the Run and Debug options:

In the Valgrind tab in the Run toolwindow you’ll get all the possible errors found by Valgrind, along with the source code location and a stack trace:

C++ support improvements

This build also brings a set of improvements to C++ language engine, which reduces the number of incorrect warnings and errors in code analysis:

  • False error for variadic function declaration when comma before ellipsis is absent (CPP-5811)
  • False syntax error for override function with try/catch block (CPP-9143)
  • Incorrect parsing in case of unnamed-only function parameters (CPP-2755)
  • Macro call breaks parsing of types (CPP-4314)
  • Braces init list is not parsed inside parent initializer (CPP-7608)
  • Parentheses in array-of-pointers argument declaration confuse CLion (CPP-8331)
  • And more

Partial commits in Git

Partial Git commits (git add -p) are now supported in CLion. That means only the selected changes from the file are committed, while other changes can be moved to another changelists. Moreover, you can now associate the code chunks, not the whole file, with a changelist, and track them separately.

You can include code chunks into a commit using the checkboxes in the Diff pane of the Commit Changes dialog:

or right from the editor, in the popup which appears when you click on a change marker in the gutter:

That’s it! Full release notes are available by the link.

    Anastasia, when do we expect to receive the 2018.1 stable? (non-EAP)

  2. Roman says:

    This version set a new record for “Resolve operation requires more time…”. I have waited 3 minutes!! to switch from myclass.h to myclass.cpp :(

  3. Tano says:

    Question, perhaps offtopic: with latest EAP I get code analysis before commiting, which I disabled in the past, but it seems that it happens again. How can I disable it now?

  4. Adam Getchell says:

    CLion 2018.1 EAP is incompatible with using Ninja in the same directory.

    In CLion 2017.3 and 2017.3 EAP, I could run a script to build out of source into build using Ninja, and then just use CLion’s Reload CMake Project.

    Now Reload CMake Project warns that it’s incompatible with Ninja, and wants to specify another directory. Unfortunately, I actually need both to build at the same place (especially until CLion Ninja compatibility is done.)
