Configuring Port Mode Alignment

The number of spaces before and after each port mode (‘in’, ‘out’, ‘inout’, ‘buffer’, ‘linkage’) can be individually set. This is accomplished using the spaces_before and spaces_after options for those rules.

Option	Values	Default Value	Description
`spaces_before`	integer > 0	1	Sets the number of spaces required before the mode
`spaces_after`	integer > 0	Rule dependent	Sets the number of spaces required after the mode

This is an example of how to configure these options.

rule :
  port_007:
     spaces_before: 1
     spaces_after : 4

Example: Align modes to the left (default)

rule :
  port_007:
     spaces_before: 1
     spaces_after : 4
  port_008:
     spaces_before: 1
     spaces_after : 3
  port_009:
     spaces_before: 1
     spaces_after : 1

which results in the following format being enforced:

I_INPUT  : in    std_logic;
O_OUTPUT : out   std_logic;
IO_INOUT : inout std_logic;

Example: Align modes based on type

rule :
  port_007:
     spaces_before: 1
     spaces_after : 4
  port_008:
     spaces_before: 3
     spaces_after : 1
  port_009:
     spaces_before: 1
     spaces_after : 1

would result in the following format being enforced:

I_INPUT  : in    std_logic;
O_OUTPUT :   out std_logic;
IO_INOUT : inout std_logic;
