- Semantic code completion using autocomplete-plus
- Diagnostics using linter
- Native C++ v8 Node module using LibClang, no 3rd party dependencies.
- Fast low-latency completions
- Easy to setup with your project, no external configuration needed
- Per project configuration supported with Project Manager
Since this is a package uses C++, it will require the package to be compiled. This is automatically done for you by Atom, but it does have some requirements.
- C++11 compiler, either GCC or Clang
- LibClang 3.8 or greater
LibClang is detected via
llvm-config command. It needs to build and link against the LibClang headers and library. It attempts to find the newest version of
llvm-config it can on your system. One can override the search by having the
LLVM_CONFIG environment variable set, e.g.
LLVM_CONFIG=/opt/clang+llvm-3.9.0-x86_64-linux-gnu-ubuntu-16.04/bin/llvm-config. Currently, I do not know of way "at package install time" through Atom to let the user specify which one to use. See llvm-config.sh.
On Linux, any distro provided libclang versions 3.8 or 3.8 should work, LLVM's Apt, or directly from LLVM. On Mac, the easiest way to upgrade to an atom-clang compatible LLVM version is with MacPorts, Homebrew, or directly from LLVM.
Currently, this only works on Linux and Mac. I do not have a Windows computer. I would welcome any patches / pull requests to add Windows support.
This package should be installed through the Atom package manager. Search for package named atom-clang. For the bleeding edge, you can clone this repository and link it into Atom with
apm if desired.
This package can work out-of-the-box, but usually requires some minor configuration. This is because parsing with LibClang, literally runs
clang over your source files and usually needs the
CXXFLAGS one would use to compile.
You can set global
CXXFLAGS. This will work for any random projects without any major flags.
Per Project Configuration
Per project configuration with Atom is an ongoing open feature request. Thankfully, Project Manager gives us at least 99% of what we want. It does require you to manually edit the project settings file.

Please report all issues in the issue tracker.
The more information you can include, the better. CFlags/CXXFlags especially. Having a reproducible test case would also greatly increase the debug time, though I realize that is not always possible.
I would love the roadmap to be largely driven by users, but her is a list I came up to get started.
- Add status bar indications for background processing of parsing, completions... Some large C++ can take time to parse/complete..
- Add support for compile_commands.json
- Add support for precompiled headers
- Replace linter (I find the interface unsuited for C++ linting, and to be frank, very buggy)
- Add support for FixIt
- Add support for ctrl-click code navigation
