Let's start the discussion on Types of Formatter in C++

C++ Formatter

C++ formatter is a tool or software program to be had within the marketplace to layout/ enhance the c++ source code in the desired format. C++ formatter software gives many coding fashion schemes which assist in formatting with the proper indentation of the source code in various styles or keeping with the particular requirements of the programmer. Those code formatters are also called beautifier gear within the market. Formatting of supply code is just as it facilitates in the clean information and improves the computer virus looking which in turn saves a variety of time and money.

Need of C++ Formatters in Source Code

Let us understand the need for C++ formatters with the help of an example:

Code:

#include <iostream>
using namespace std;
intmain()
{
int num1, num2, add;
cout<< "Enter the first integer";
cin>> num1;
cout<< "Enter the second integer";
cin>> num2;
add = num1 + num2;
// Printing the addition result
cout<< "The result is " <<add ;
return 0;
}

The above code is the simple addition of 2 integer numbers. But the way it is written makes it very uneasy or difficult to understand. There is a need for proper indentation, required spaces in the code. Code after ‘{‘ should be written should be indented properly to show that the required block of code is a part of it. It should be formatted as given below:

#include <iostream>
using namespace std;
intmain() {
int num1, num2, add;
cout<< "Enter the first integer";
cin>> num1;
cout<< "Enter the second integer";
cin>> num2;
add = num1 + num2;
// Printing the addition result
cout<< "The result is " << add;
return 0;
}

Types of C++ Formatters

There are a lot of formatters / beautifiers available in the market. Let us understand some of the commonly used formatters in detail:

  • Clang-Format

Clang-Format is one of the most popular and typically used open-source formatters used to format c, c++, and goal c supply code. It robotically formats the c++ code and facilitates higher expertise of code. It's miles programmed in c++ and python language. In order to format the source code automatically according to Electron C++, we need to run the following command:

clang-format -i file_path.cc

Users can also perform the formatting of code according to the specific requirements (other than the one available by default) by inserting the style in the ‘.clang-format’ file or using the option -style = “{key: value, ….}”.

  • Artistic Styler

The artistic styler is a well-known formatter and beautifier used to indent the source code of c, c++, cli, and java language. To deal with the problem of many formatters for putting the areas in the location of tabs (inability to distinguish among tabs and areas in source code), creative fashion was evolved in April 2013. It is written in c++ language and can re-indent and re-layout the source of various languages nicely. It may be utilized by the programmers/ testers immediately as a command line or it can additionally be protected in the existing program’s library. This beautifier is to be had for windows, Linux, and Mac as well.

  • PrettyPrinter

Quite printers and beautifiers are important gear at the same time as coding in programming languages like c++. It accepts the source code report and generates the opposite equal code report with the right layout and the indentation in step with the respective syntax and control statements. The main reason for prettyprinter is the right indentation of code which helps in revealing the nesting of capabilities, loops with their right beginning and closing braces. Long strains may be folded into smaller ones using the respective capabilities which allows within the true clarity of code. It enables in revealing many syntactical mistakes to the programmer.

  • Jindent

Jindent is one of the maximum powerful and usually used equipment used to enhance the source code of java, c, and c++ languages. It routinely indents the code in line with the syntax and correct coding conventions which facilitates locating the insects within the code and saves time. One of the cool capabilities of the incident is that it gives the plugin for almost all famous ide’s like a visible studio, eclipse, Netbeans, and so forth so that it could be used easily through the programmers/ testers operating on them. It permits its invocation from the shell scripts. Jindent affords help for all of the operating systems is it windows, mac, or Linux. It's miles evolved in natural java language and one wishes to have a java runtime surroundings to paintings nicely on it. Jindent could be very user-pleasant because it provides the GUI so that the user can perform moves like formatting settings, converting the environment variables, and so forth very without difficulty.

  • Highlighter

It is also one of the most normally used formatters used to format the source code of c++, Perl, HTML, and a few other languages as well. It is very consumer-friendly and for this reason quite simple to apply. Customers just need to copy the source code inside the preferred text subject, pick the c++ language, and style dropdown to have the required formatting. It gives different interesting functions as well like one also can pick out to look the line numbers on the left side of code, can at once insert the source code within the HTML web page without including any outside CSS and javascript report to it.
