Extend rule concurrent_009 for manually broken lines #1456
Description
Is your feature request related to a problem? Please describe.
When it comes to long lines, I sometimes want to break long concurrent assignments like this:
architecture a of b is
begin
-- Breaking the long assignment like this ensures the length limit of 120
-- characters is met.
my_very_long_concurrent_011_signal <=
my_very_long_concurrent_003_signal(my_long_port_name_vector'length -1 downto 0) when select_value = '0' else
my_very_long_concurrent_003_signal(3 downto 0);
end architecture a;For this to work concurrent_011, which enforces no new line after assignment operator, must be disabled.
However, concurrent_009 either has to be disabled as well, or align_left has to be set to yes. The problem is, that I would like to have the rule enabled and align_left set to no, so that the following format is nicely enforced:
architecture a of b is
begin
my_concurrent_009_signal <= '0' when select_value = "1001" and foo = '0' else
'1';
end architecture a;Which ultimately destroys the desired formatting of the first example. And the result again violates the line length limit of 120 characters.
architecture a of b is
begin
-- Line exceeds line length limit!
my_very_long_concurrent_011_signal <=
my_very_long_concurrent_003_signal(my_long_port_name_vector'length -1 downto 0) when select_value = '0' else
my_very_long_concurrent_003_signal(3 downto 0);
end architecture a;Describe the solution you'd like
architecture a of b is
begin
-- This works
my_very_long_concurrent_011_signal <=
my_very_long_concurrent_003_signal(my_long_port_name_vector'length -1 downto 0) when select_value = '0' else
my_very_long_concurrent_003_signal(3 downto 0);
-- And this also works at the same time
my_concurrent_009_signal <= '0' when select_value = "1001" and foo = '0' else
'1';
end architecture a;With an additional value for align_left, e.g. on_new_line_after_assign one could enable this behavior. In the code we can check if the assignment is on a new line and if so, enforce left alignment.
