This utilities with CLI (Command Line Interface) for normalize indentation in your source code.

Add this line to your application's Gemfile:

gem 'indent_code'

And then execute:

$ bundle

Or install it yourself as:

$ gem install indent_code

You can use this utilities for alignment code for any language, where block syntax is defined as: '{' ... '}', C,C++,Java ... etc. For details, use option -h or --help.

File for normalize 'test.c':

 #include <stdlib.h>

///Test function - 1. }
 void test1 ( void )
{
  switch(c) {
    case 4:
      c = "** \" { \" ";
      break;
    }
    
    if (c) 
      {
	return 1;
      }
}

/**
 * Test function - 2. {
 */
void test2 ( void )
{
  int a = '{';
  /*
* Simple comment block.
        * Check align into comments.
	*/
{
  a = '\'';
}
return a;
}

Run indent gem:

$ indent test.c

and get follow result after normalize:

#include <stdlib.h>

///Test function - 1. }
void test1 ( void )
{
    switch(c) {
        case 4:
        c = "** \" { \" ";
        break;
    }
    
    if (c)
    {
        return 1;
    }
}

/**
 * Test function - 2. {
 */
void test2 ( void )
{
    int a = '{';
    /*
     * Simple comment block.
     * Check align into comments.
     */
    {
        a = '\'';
    }
    return a;
}

Also you can set indent size -i 4 (set TAB size = 4 chars) and clean source code, by used -c option. Clean option deleted code blocks framed is a: #if 0 ... #endif.

$ indent test.c -c

#include <stdlib.h>

#if EDEF
//Some text - 1.
# if 0
Deleted text.
# endif
//Some text - 2.
#endif

We get follow result after clean:

#include <stdlib.h>

#if EDEF
//Some text - 1.
//Some text - 2.
#endif
