What’s New

Doxygen-styled docs viewer

If a project includes Doxygen-styled documentation, you can easily preview it in the Quick Documentation pop-up Ctrl+Q. It includes Doxygen-styled information (parsed and formatted) along with the type information.

Safe Rename

Rename Shift+F6 a function or its parameters and be sure CLion will update the corresponding information in the Doxygen comments for you.

Completion

When writing Doxygen comments, benefit from auto-completion for Doxygen commands and function parameter names.

Doxygen comments generation

Stubs for Doxygen comments can be generated automatically with CLion. If your function has parameters, returns a value or throws an exception, type “/**”, “/*!”, “///” or “//!” and then press Enter to generate a Doxygen stub for the function.

Generate operators

CLion is ready to help you with boilerplate code. With version 2016.2 generate equality, relational and stream output operators in one click. Select std::tie, 'generate as class members' and other options as necessary.

Generate definitions

A new setting called Generate in-place makes the Generate Definitions dialog more flexible. The defaults for this setting depend on your code, and heuristics are implemented to support the most common cases (like header-only or cpp-only classes).

With the updated Complete Statement Shift+Ctrl+Enter in CLion, parentheses, braces, semicolons, quotes, etc. are inserted as necessary and the caret is moved automatically so you can start typing the next statement.

Performance improvements

Along with plenty of correctness and ‘command timeout’ fixes in the debugger drivers (both GDB and LLDB), this version brings changes that affect debugging startup/shutdown, stepping with various data views, and expanding big data structures. For many of them performance has been improved greatly.

Read more about the changes

LLDB on Linux

LLDB is now available not only on macOS, but on Linux as well. Select between the bundled GDB or LLDB, or a custom GDB version.

Attach to local process is now possible on Linux with either LLDB or GDB.

Remote GDB debug

CLion 2016.2 supports remote debugging with GDB/gdbserver. Start the program under gdbserver on target machine, and then connect to it from CLion running on another one (macOS or Linux). Inspect the code using breakpoints, expression evaluation, watches and other benefits of the IDE’s built-in debugger UI.

Watches and Variables

The Watches view has been merged with the Variables view so you no longer need to switch between them. But if you feel more comfortable with the previous layout, feel free to switch this mode off and keep things as they are.

Coding assistance

Writing CMake files gets easier with code completion and navigation actions such as Go to declaration/definition for user symbols in CMake (like functions or macros). Also, you can now view Quick Definitions Shift+Ctrl+I for such symbols.

Rename for users symbols

In addition to coding assistance, CLion 2016.2 supports Rename refactoring Shift+F6 for user symbols in CMake. This results in safer renaming for such symbols as CLion updates all the usages automatically.

Safe delete

Get CMake commands updated automatically when you delete files from your project. CLion will either remove the file reference from the command arguments, or warn you about a possibly incorrect command after deletion.

Live templates for Boost

CLion 2016.2 adds an updated boost template, as well as a new boost_with_libs that helps link your target with Boost libraries.

CLion environment variable

In order to detect if CMake on your project was run from CLion, and if so, set special variables/paths or execute some additional scripts of your choice, CLion 2016.2 sets an environment variable (CLION_IDE) that you can check in your CMake files.

Auto-completion for environment variables helps you type them easier.

New code style settings

With plenty of formatting settings available in CLion, you’ve always been able to flexibly configure your preferred code style. CLion 2016.2 adds a few new settings to fine-tune wrapping for lines after function return type, lambda capture list, and in << and >> operators.

LLVM/LLDB code styles

Predefined code styles provide you with ready-to-use code styles, or can be used as a basis for your custom style. In the 2016.2 release, you get LLVM and LLDB styles.

Ligatures

To use fonts with ligatures (e.g. FiraCode, Hasklig, Monoid or PragmataPro) now go to Editor | Colors & Fonts | Font settings, choose a corresponding font, and select the ‘Enable font ligatures’ option.

Editor background

Customize the look of your editor in CLion 2016.2 by calling Set Background Image action from Find Action Shift+Ctrl+A. Select an image, configure its settings in the dialog, and enjoy your custom background as you code.

Alphabetical sorting in Structure View

Structure view Alt+7 lets you navigate across the structure of the current file. By default, its entities are grouped by type (namespaces, structures, classes, etc.) in the same order as the original file. CLion 2016.2 adds the option to sort them alphabetically, which makes more sense for long files.

Inspections tool window

The updated Inspection window gives you an immediate code preview and allows you to apply a quick-fix or suppress the inspection in-place.

Unversioned files

Now it's easier than ever to remember about important files not yet under version control when committing. CLion shows them clearly in the commit dialog.
