Is there any way to beatify the html that is emitted?  Some of the
html that I generate dynamically is poorly formatted, and it would be
somewhat difficult to make it pretty (particularly in the context of
the static html that surrounds it).  It there a mechanism by which I
can (for debugging purposes at least) beatify the final html?

For example, is there a hook that allows one to intercept the
generated html and apply final processing before emitting it?

Or perhaps there is an option in the Webrick server to beatify the

Or perhaps something else?

Get Tidy, and run this assertion from your functional tests:

  def assert_tidy(messy = @response.body, verbosity = :noisy)
    scratch_html = RAILS_ROOT + '/../scratch.html'  #  TODO  tune me!, 'w'){|f|  f.write(messy)  }
    gripes = `tidy -eq #{scratch_html} 2>&1`
    exclude, inclued = gripes.partition do |g|
      g =~ / - Info\: / or
      g =~ /Warning\: missing \<\!DOCTYPE\> declaration/ or
      g =~ /proprietary attribute/ or
      g =~ /lacks "(summary|alt)" attribute/
    puts inclued if verbosity == :noisy
    #{|i| puts Regexp.escape(i) }
    assert_xml `tidy -wrap 1001 -asxhtml #{scratch_html} 2>/dev/null`
      #  CONSIDER  that should report serious HTML deformities

You can take out the assert_xml if you don't have yar_wiki (whence that

The system will push a scratch.html file into your parent folder, and if
errors Tidy reports are not utterly trivial, it will barf them out when
tests run.

When upgrading old websites to Rails I always run things through
Tidy -i -asxhtml, before inserting the <%%> tags. The difference in
development speed is astounding, when I don't need to count the freakin'
tags just to nest everything correctly.

My Short Cut with O'Reilly has lots more tips on keeping the HTML clean.

You could switch to markaby which makes you write everything in Ruby
(akin to XmlBuilder) and emits pretty HTML (I'm pretty sure).

Thanks to everybody for the helpful responses.

It is useful to me when I examine my output.
