Configuring Multiline Indent Rules

There are rules which will check indent of multiline expressions and conditions.

There are several options to these rules:

Option	Values	Default	Description
`align_left`	`yes`, `no`	`yes`	`yes` = Lines will be aligned left `no` = Lines will be aligned to assignment operator
`align_paren`	`yes`, `no`	`no`	`yes` = Align to unbalanced open parenthesis `no` = Each unbalanced open parenthesis will add an indent.

This is an example of how to configure the option.

rule :
  concurrent_003:
     align_left : "no"
     align_paren : "yes"

All examples use the following code snippet:

wr_en <= resize(unsigned(I_FOO) +
            unsigned(I_BAR), q_foo'length);

wr_en <=
    resize(unsigned(I_FOO) +
                    unsigned(I_BAR), q_foo'length);

Example: `align_left` set to `yes` and `align_paren` set to `no`

wr_en <= resize(unsigned(I_FOO) +
    unsigned(I_BAR), q_foo'length);

wr_en <=
  resize(unsigned(I_FOO) +
    unsigned(I_BAR), q_foo'length);

Example: `align_left` set to `no` and `align_paren` set to `no`

wr_en <= resize(unsigned(I_FOO) +
           unsigned(I_BAR), q_foo'length);

wr_en <=
         resize(unsigned(I_FOO) +
           unsigned(I_BAR), q_foo'length);

Example: `align_left` set to `yes` and `align_paren` set to `yes`

wr_en <= resize(unsigned(I_FOO) +
                unsigned(I_BAR), q_foo'length);

wr_en <=
  resize(unsigned(I_FOO) +
         unsigned(I_BAR), q_foo'length);

Example: `align_left` set to `no` and `align_paren` set to `yes`

wr_en <= resize(unsigned(I_FOO) +
                unsigned(I_BAR), q_foo'length);

wr_en <=
         resize(unsigned(I_FOO) +
                unsigned(I_BAR), q_foo'length);
