Step-by-Step Guide: Installing Betty Linter for Clean C Code

What is Betty?

Betty is a set of rules or guidelines that help programmers write code in a clean and consistent way. Betty in C programming is a guide that helps you write code that is neat, organized, and easy to comprehend, making the coding experience smoother for everyone involved.

The importance of Betty

1. Betty enables you to write code that is easy to read and understand.

2. Well-organized code is easier to maintain, and bugs can easily be detected and fixed.

3. Betty enables beginners to learn the best coding style.

4. adhering to the Bitty Code shows professionalism

5. Code written with Betty is easy to debug.

When coding with Betty, we have to follow her style and documentation.

How to install betty

1. Make a directory called betty and cd into the directory

    mkdir betty
    cd betty
   

   You can copy those commands into your terminal.

2. Go to the betty repository and clone it. This is a link to the repository [https://github.com/alx-tools/Betty.git].

   

3. Then cd into the Betty repo.

    cd Betty
   

   1. Now we have to install the linter. A linter is a program that analyzes your source code to find and highlight potential issues, style violations, or other discrepancies.

       sudo ./install.sh
      

      

      1. Create a file called Betty; you can simply do that by following this code.

          vi betty
         

         1. Inside this file, copy this code and paste it there.

             #!/bin/bash
             # Simply a wrapper script to keep you from having to use betty-style
             # and betty-doc separately on every item.
             # Originally by Tim Britton (@wintermanc3r), multiargument added by
             # Larry Madeo (@hillmonkey)
            
             BIN_PATH="/usr/local/bin"
             BETTY_STYLE="betty-style"
             BETTY_DOC="betty-doc"
            
             if [ "$#" = "0" ]; then
                 echo "No arguments passed."
                 exit 1
             fi
            
             for argument in "$@" ; do
                 echo -e "\n========== $argument =========="
                 ${BIN_PATH}/${BETTY_STYLE} "$argument"
                 ${BIN_PATH}/${BETTY_DOC} "$argument"
             done
            

1. The next thing to do is to change the permissions so all users can have access to them.

    chmod a+x betty
   

   1. Next, we have to move it to the bin directory

       sudo mv betty /bin/
      

      

      Now we have successfully installed Betty. Let's now test it. Create a simple C code file to test with these codes.

       #include <stdio.h>
      
       /**
        * main - Entry point of the program
        *
        * Return: 0 on success, non-zero on failure
        */
       int main(void)
       {
           /* Declare variables */
           int num1 = 5;
           int num2 = 10;
           int sum;
      
           /* Calculate the sum of num1 and num2 */
           sum = num1 + num2;
      
           /* Display the result */
           printf("The sum of %d and %d is: %d\n", num1, num2, sum);
      
           /* Return 0 to indicate successful execution */
           return (0);
       }
      

      Save the file with file1, then run the command betty file1. Tell me what you saw and observed in the comment section.
