Creating a C/C++ Code Formatting tool with help of Clang tools

Last Updated : 16 Jul, 2020

Today we are going to discuss formatting files in the user's workspace by their extension. For this we are going to make use of Clang's format tools. Prerequisites:

Linux Machine
Python
Clang Tool

Setup:

Install Python using the following command:
```
sudo apt-get install python
```
Install Clang Format Tools
```
sudo apt-get install clang-format-3.5
```

Create a python file named format-code.py at any location where you have read and write permissions. In this example we are going to create it in /home/user/. It shall contain the following code:
Create format specification file and copy it to project's top level directory , e.g., /home/user/myproject/
1. Create formatting file (in example, we are creating google coding style tool)
```
clang-format-3.5 -style=google -dump-config > .clang-format 
```
2. Copy it to project's directory i.e., it's location becomes: /home/user/myproject/.clang-format

How to use it?

Navigate to the directory whose files you want to format, e.g.,
```
cd /home/user/myproject/c-source/
```
Run the format-code file that you created earlier
```
python /home/user/format-code.py
```
