    copied!<p>Is this actually doable? I have some very long regex pattern rules that are hard to understand because they don't fit into the screen at once. Example:</p> <pre><code>test = re.compile('(?P&lt;full_path&gt;.+):\d+:\s+warning:\s+Member\s+(?P&lt;member_name&gt;.+)\s+\((?P&lt;member_type&gt;%s)\) of (class|group|namespace)\s+(?P&lt;class_name&gt;.+)\s+is not documented' % (self.__MEMBER_TYPES), re.IGNORECASE) </code></pre> <p>Backslash or triple quotes won't work.</p> <p>EDIT. I ended using the VERBOSE more. Here's how the regexp pattern looks now:</p> <pre><code>test = re.compile(''' (?P&lt;full_path&gt; # Capture a group called full_path .+ # It consists of one more characters of any type ) # Group ends : # A literal colon \d+ # One or more numbers (line number) : # A literal colon \s+warning:\s+parameters\sof\smember\s+ # An almost static string (?P&lt;member_name&gt; # Capture a group called member_name [ # ^: # Match anything but a colon (so finding a colon ends group) ]+ # Match one or more characters ) # Group ends ( # Start an unnamed group :: # Two literal colons (?P&lt;function_name&gt; # Start another group called function_name \w+ # It consists on one or more alphanumeric characters ) # End group )* # This group is entirely optional and does not apply to C \s+are\snot\s\(all\)\sdocumented''', # And line ends with an almost static string re.IGNORECASE|re.VERBOSE) # Let's not worry about case, because it seems to differ between Doxygen versions </code></pre>
