What Code::Blocks is

Code::Blocks is an IDE for C, C++ and Fortran, available for Linux, macOS and Windows. It is free, with no paid tiers stated. Its editor offers syntax highlighting, code folding, tabs, code completion, a class browser and smart indentation. A custom build system supports parallel builds, multi-target projects, workspaces and inter-project dependencies. Listed compiler options include GCC, MSVC++, clang, Digital Mars, Borland C++ 5.5 and Open Watcom. For debugging, it connects to GNU GDB and also supports MS CDB, which the site says is not fully featured. The IDE can import MSVC projects and workspaces, but assembly code is not supported in those imports; it also imports Dev-C++ projects. A plugin framework lets users install or write extensions. Some plugins ship with official releases, while others are managed externally. Code::Blocks is distributed under GNU GPL version 3; its SDK uses GNU LGPL version 3, allowing closed-source plugins to link against it. The site offers a manual, wiki and forums for help and discussion.
