A cross-platform IDE for C and C++
A power tool
for a power language
Who wouldn’t like to code at the speed of thought while the IDE does all the mundane development tasks for them? But is that really possible for a tricky language like C++, what with its modern standards and heavily templated libraries? Why, yes, yes it is! See it to believe it.
Smart C and C++ editor
Read and write code effectively with an editor that deeply understands C and C++. Have completion results filtered by type in Smart Completion. Use Breadcrumbs to track your location inside the hierarchy of scopes. Gain insight into function calls thanks to parameter name hints. Find the context usages of a symbol or simply jump to it by typing its name. CLion will even make sure your code conforms to coding guidelines, including formatting, naming, and more.
Generate tons of boilerplate code instantly. Override and implement functions with simple shortcuts. Generate constructors and destructors, getters and setters, and equality, relational, and stream output operators. Wrap a block of code with a statement, or generate a declaration from a usage. Create custom live templates to reuse typical code blocks across your code base to save time and maintain a consistent style.
Rename symbols; inline a function, variable, or macro; move members through the hierarchy; change function signatures; and extract functions, variables, parameters, or a typedef. Whichever automated refactoring you use, rest assured CLion will safely propagate the appropriate changes throughout your code.
Inspect the code under the caret to learn just about anything: function signature details, review comments, preview Doxygen-style documentation, check out the inferred type for symbols lacking explicit types, and even see properly formatted final macro replacements.
Code analysis on the fly
Create code that’s beautiful and correct. With CLion, potential code issues are detected instantly, as you type…
…and can be fixed at the touch of a button, while the IDE correctly handles the changes.
CLion runs its code analysis, Data Flow Analysis, other Clangd-based checks, and Clang-Tidy to detect unused and unreachable code, dangling pointers, missing type casts, no matching function overload, and many other issues.
Investigate and solve problems with ease in CLion’s friendly debugger, with GDB or LLDB available as the backend.
Attach to local processes or debug remotely. For embedded development, rely on OpenOCD and Embedded GDB Server configurations to do on-chip debugging with CLion.
Dive deeper with disassembly and memory views, and peripheral view for embedded devices.
Use line, symbol, exception, and conditional breakpoints to inspect your code’s execution. Log the events, remove breakpoints once hit, or disable them until another one is hit. All of this can be configured in a dedicated dialog.
Make use of the Watches and the Variables views, or evaluate the result of a function call or some complicated expression when stopping at some execution point.
View values inline
Get a full view of your project with variables’ values shown right in the editor as you debug – with no need to switch to the Variables tab in the Debug tool window!
Fully Integrated C/C++ Development Environment
CLion works with CMake, Gradle C++ and compilation database project models, using all the information from there during code editing and refactorings.
Everything you need in one place
Everything you need for your everyday development is included: all popular VCS (Subversion, Git, GitHub, Mercurial, CVS, and Perforce), Google Test, Boost.Test and Catch frameworks for unit testing, Doxygen and Database tools.
To help you focus on code and raise your productivity, CLion has keyboard shortcuts for nearly all its features, actions and commands.
Vim fans are welcome to install the Vim-emulation plugin.
Local and remote work
With embedded terminal, run any command without leaving the IDE: locally or remotely using the SSH protocol.
After editing your code locally, build, run or debug your application or unit tests locally or remotely.
