About

In 2015, juCi++ was one of the first IDEs to utilize libclang for improved C/C++ tooling. The integrated C/C++ support has since then improved steadily, and support for other languages has been made possible through the language server protocol. The main goals of juCi++ is effective resource usage, stability, and ease of use. Instead of relying on 3rd party addons, features expected in an IDE is instead integrated directly into juCi++.

For effective development, juCi++ is primarily written for Unix/Linux systems. However, Windows users can use juCi++ through POSIX compatibility layers such as MSYS2.

Features

• Platform independent
• Fast, responsive and stable (written extensively using C++11/14 features)
• Syntax highlighting for more than 100 different file types
• Warnings and errors on the fly
• Fix-its, as well as C/C++ standard header include suggestions
• Integrated Clang-Tidy checks can be enabled in preferences
• Debug integration, both local and remote, through lldb
• Supports the following C/C++ build systems directly (other build systems need manually generated compilation databases):
  • CMake
  • Meson
• Fast autocompletion
• Tooltips showing type information and documentation
• Rename refactoring across files
• Highlighting of similar types
• Automated documentation search for C/C++ identifiers
• Go to declaration, implementation, methods and usages
• OpenCL and CUDA files are supported and parsed as C++
• Non-C/C++ files are supported through the Language Server Protocol, which is enabled if an [language identifier]-language-server executable is found. This executable can be a symbolic link to one of your installed language server binaries.
  • For additional instructions, see: setup of tested language servers
• Non-C/C++ projects are also supported, such as Python, JavaScript, and Rust projects
• Git support through libgit2
• Find symbol through Ctags (Universal Ctags is recommended)
• Spell checking depending on file context
• Run shell commands within juCi++
• ANSI colors are supported. Enable for instance by setting the environment variables CLICOLOR=1 CLICOLOR_FORCE=1 before starting juCi++. Colored diagnostics from clang is enabled through the flag -fcolor-diagnostics, and gcc uses the flag -fdiagnostics-color.
• Regex search and replace
• Smart paste, keys and indentation
• Extend/shrink selection
• Multiple cursors
• Snippets can be added in ~/.juci/snippets.json using the TextMate snippet syntax. The language ids used in the regexes can be found here: https://gitlab.gnome.org/GNOME/gtksourceview/tree/master/data/language-specs.
• Auto-indentation through clang-format or Prettier if installed
• Source minimap
• Split view
• Zen mode
• Full UTF-8 support
• Wayland supported with GTK+ 3.20 or newer
