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");
}
An exception to the behavior occurs when there is a comment
between the right brace and the subsequent else statement. While
the '-br' option will cause a left brace to jump over the
comment, the else does not jump over the comment to cuddle
because it has a strong likelihood of changing the meaning of the
comment.
The '-cdw' option 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 '-slc' option allows for an unbraced conditional and its
inner statement to appear on the same line. For example:
if (x) x--;
else x++;
Without '-slc' that code would appear as
if (x)
x--;
else
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 between a
cast operator and the object to be cast. The '-ncs' ensures that
there is no space between the cast operator and the object.
Remember that indent
only knows about the standard C data types
and so cannot recognise user-defined types in casts. Thus
(mytype)thing
is not treated as a cast.
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 a for
and the following
parenthesis. This is the default.
The '-sai' option forces a space between a if
and the following
parenthesis. This is the default.
The '-saw' option forces a space between a while
and the
following parenthesis. This is the default.
The '-prs' option causes all parentheses to be separated with a
space from whatever 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++ = ' ';
}
