juCi++ Build Status Build status

a lightweight, platform independent C++-IDE with support for C++11, C++14, and experimental C++17 features depending on libclang version.


Current IDEs struggle with C++ support due to the complexity of the programming language. juCI++, however, is designed especially towards libclang with speed, stability, and ease of use in mind.


  • Platform independent
  • Fast, responsive and stable (written extensively using C++11/14 features)
  • Syntax highlighting for more than 100 different file types
  • C++ warnings and errors on the fly
  • C++ Fix-its
  • Debug integration, both local and remote, through lldb
  • Automated CMake processing, including support for external libraries
  • Git support through libgit2
  • Fast C++ autocompletion
  • Keyword and buffer autocompletion for other file types
  • Tooltips showing type information and doxygen documentation (C++)
  • Rename refactoring across files (C++)
  • Highlighting of similar types (C++)
  • Automated documentation search (C++)
  • Go to declaration, implementation, methods and usages (C++)
  • Find symbol through Ctags
  • Spell checking depending on file context
  • Run shell commands within JuCi++
  • Regex search and replace
  • Smart paste, keys and indentation
  • Auto-indentation of C++ file buffers through clang-format
  • Source minimap
  • Split view
  • Full UTF-8 support
  • Wayland supported with GTK+ 3.20 or newer

See enhancements for planned features.
