Testing equality of booleans to true or false

When using booleans, it is unnecessary to test whether they’re equal to true (rule 185) or false (rule 186). Simply testing the boolean results in cleaner code.

signal valid: boolean;
-- some code omitted
if valid then
   -- ...
end if;

if valid = true then
   -- ...
end if;

if not valid then
   -- ...
end if;

if valid = false then
   -- ...
end if;

if valid /= true then
   -- ...
end if;

Note that the equals-false rule (186) is disabled (set to IGNORE) by default.

Project specific setting of these rules

These rules can be disabled for your project, or its severity can be modified in the project linting settings.

Manual configuration in ${project location}/.settings/com.sigasi.hdt.vhdl.linting.prefs:

185/severity/<project>=IGNORE

186/severity/<project>=IGNORE
