empty_if_block

This lint rule checks for empty blocks in if, elseif, and else statements.

Why this is discouraged

Empty conditionals are indicative of incomplete or poorly written code and detract from readability.

Options

This rule accepts the following configuration options:

• comments_count (boolean, default: false): When set to true, blocks that contain only comments are not considered empty and will not trigger a warning.

Example violations

empty_if_block will warn on the following:

if condition then
end

if condition then
    -- Empty then block
elseif otherCondition then
    doSomething()
end

if condition then
    doSomething()
else
    -- Empty else block
end

Configuration

To treat blocks with only comments as non-empty, configure the rule with comments_count: true:

-- This will not trigger a warning when comments_count is true
if condition then
    -- TODO: implement this later
end

	lute = {
        lint = {

                    options = {
                        comments_count = true,
                    },
                },
            } 
        }
    },
