Merging collapsible if statements increases the code’s readability.
Noncompliant Code Example
if !filename.nil?
if File.file?(filename) || File.directory?(filename)
# ...
end
end
if a then
unless b then
# ...
end
end
Compliant Solution
def isFileOrDirectory(filename)
File.file?(filename) || File.directory?(filename)
end
# ...
if !filename.nil? && isFileOrDirectory(filename)
# ...
end
if a && !b then
# ...
end
