Tidy html output?

[Robin Manoli]

Hey!

I'm wondering if there is a way to make the html output beautifully indented and more easily readable?

I just wrote that function check it out.

def pretty_html(obj):
    import xml.dom.minidom as xml
    declaration = len(xml.Document().toxml())+1
    doc = xml.parseString(obj.xml())
    return XML(doc.toprettyxml()[declaration:])

Where obj is a web2py helper. You can easily change it to accept plain text.

Sorry for a late reply!

How would I implement this? What I would like to do is to render pretty html in development mode (I have a global variable development_mode = True). Would I have to render the views myself? It would really be nice if I somewhere could just tell web2py in one place to render all views like that, or perhaps it would be better if I could decorate a controller with it (how?)?

I did write a decorator (my first) myself. It works, except adding a starting and ending comment for the pretty html code (the PRETTY function got this error: <type 'exceptions.AttributeError'> 'str' object has no attribute 'xml').

def COMMENT( text ):
    """ Create an HTML comment """
    if type(text) == type('str'):
        return XML( "<!-- %s -->" % text )
    return text

def PRETTY( html_helper ):
    """ Make HTML pretty, originally made by aleon: https://groups.google.com/d/msg/web2py/pyOosnV9AuQ/BDXzTfHYV4YJ """

    import xml.dom.minidom as xml
    declaration = len(xml.Document().toxml())+1

    doc = xml.parseString(html_helper.xml())
    return XML(doc.toprettyxml()[declaration:])

def PrettyDevHTML(func):
    """ Make html output pretty in Site.dev mode"""
    # for developing/-bugging this: http://thecodeship.com/patterns/guide-to-python-function-decorators/
    def func_wrapper(*args, **kwargs):
        result = func(*args, **kwargs)
        if development_mode:
            #result = COMMENT( 'PrettyDevHTML Start' ) + result # line doesn't work for some reason
            result += COMMENT( '/'+func.__name__ )
            #result += COMMENT( 'PrettyDevHTML End' ) # line works but redundant because starting line doesn't
            result = PRETTY( result )
        return result
    return func_wrapper

Using this function looks nice, but it does create some extra line breaks between each tag, that would be nice to get rid of if possible :)
