CppStyle for Windows Eclipse C/C++

Published:
1 minute read

If you want to format your code using clang-format in Eclipse IDE in windows do the following:

  • Install LLVM from here
  • Add LLVM binary directory to the path.
  • Add this link https://releases.llvm.org/download.html to the eclipse (help -> install new software)
  • Install CppStyle and restart Eclipse. If it occurred any problem, see here

Configure CppStyle

To configure CppStyle globally, go to Preferences -> C/C++ -> CppStyle dialog.

To enable CppStyle(clang-format) as default C/C++ code formatter, go to Preferences -> C/C++ -> Code Style -> Formatter page and switch “Code Formatter” from [built-in] to “CppStyle (clang-format)”

To configure clang-format

CppStyle does not support appending command line parameters to clang-format and cpplint.py. So, use their respective configuration files to do this.

CppStyle will pass the full absolute path of the source file to clang-format in command line. And clang-format will try to find the configuration file named .clang-format in the source file’s path, and its parent’s path if not found previously, and parent’s path of the parent and so on.

So put the configuration file .clang-format into the project’s root direcotry can make it work for all source files in the project.

Further more, you can also add the configuration file .clang-format into Eclipse workspace root directory to make it work for all projects in the workspace.

To generate the clang-format configuration file .clang-format:

clang-format -dump-config -style=Google > .clang-format

If no configure file named .clang-format is found, “-style=Google” will be passed to clang-format and Google style will be used by default.

Utilize PTX Just-In-Time (JIT) Compilation in CUDA

In this post I’ve written about how to utilize PTX Just-In-Time (JIT) compilation in CUDA. PTX is a low-level assembly-like language that is used to represent the GPU code. The PTX code is then compiled to the machine code by the NVIDIA driver at runtime. This process is called Just-In-Time (JIT) compilation. But before I write about how to use PTX JIT compilation, I’ll provide some background on why you might want to use it.

This is a collection of my dotfiles that I use on my Linux system. I have written about them in various posts, but I thought I can put them all in one place. You can checkout the github repository here, too.

Setup LAMMPS

Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) is a classical molecular dynamics code that can be used to model atoms or, more generally, as a parallel particle simulator at various scales. The complete documentation of LAMMPS can be found here. In this post, I will provide a guide on how to setup LAMMPS on a Linux machine. My setup is on a cluster with NVIDIA GPUs, UCX, and OpenMPI. Also, we have a built-in module system to load the necessary modules.
