1.6 Statements

The `-br' or `-bl' option specifies how to format braces.

The `-br' option formats statement braces like this:

 
if (x > 0) {
  x--;
}

The `-bl' option formats them like this:

 
if (x > 0)
  {
    x--;
  }

If you use the `-bl' option, you may also want to specify the `-bli' option. This option specifies the number of spaces by which braces are indented. `-bli2', the default, gives the result shown above. `-bli0' results in the following:

 
if (x > 0)
{
  x--;
}

If you are using the `-br' option, you probably want to also use the `-ce' option. This causes the else in an if-then-else construct to cuddle up to the immediately preceding `}'. For example, with `-br -ce' you get the following:

 
if (x > 0) {
  x--;
} else {
  fprintf (stderr, "...something wrong?\n");
}

With `-br -nce' that code would appear as

 
if (x > 0) {
  x--;
}
else {
  fprintf (stderr, "...something wrong?\n");
}

This causes the while in a do-while loop to cuddle up to the immediately preceding `}'. For example, with `-cdw' you get the following:

 
do {
  x--;
} while (x);

With `-ncdw' that code would appear as

 
do {
  x--;
}
while (x);

The `-cli' option specifies the number of spaces that case labels should be indented to the right of the containing switch statement.

The default gives code like:

 
switch (i)
  {
  case 0:
    break;
  case 1:
    {
      ++i;
    }
  default:
    break;
  }

Using the `-cli2' that would become:

 
switch (i)
  {
    case 0:
      break;
    case 1:
      {
        ++i;
      }
    default:
      break;
  }

The indentation of the braces below a case statement can be controlled with the `-cbin' option. For example, using `-cli2 -cbi0' results in:

 
switch (i)
  {
    case 0:
      break;
    case 1:
    {
      ++i;
    }
    default:
      break;
  }

If a semicolon is on the same line as a for or while statement, the `-ss' option will cause a space to be placed before the semicolon. This emphasizes the semicolon, making it clear that the body of the for or while statement is an empty statement. `-nss' disables this feature.

The `-pcs' option causes a space to be placed between the name of the procedure being called and the `(' (for example, puts ("Hi");. The `-npcs' option would give puts("Hi");).

If the `-cs' option is specified, indent puts a space after a cast operator.

The `-bs' option ensures that there is a space between the keyword sizeof and its argument. In some versions, this is known as the `Bill_Shannon' option.

The `-saf' option forces a space between an for and the following parenthesis. This is the default.

The `-sai' option forces a space between an if and the following parenthesis. This is the default.

The `-saw' option forces a space between an while and the following parenthesis. This is the default.

The `-prs' option causes all parentheses to be seperated with a space from the what is between them. For example, using `-prs' results in code like:

 
  while ( ( e_code - s_code ) < ( dec_ind - 1 ) )
    {
      set_buf_break ( bb_dec_ind );
      *e_code++ = ' ';
    }
