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 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++ = ' '; } |
