 # tidy_pt_wrapper lint wrapper for Chameleon and ZPT templates.  Written to
 # run under SublimeLinter, but will probably work elsewhere.
 #
 # When run from the command line it invokes tidy-html5 and scrapes and
 # modifies its stderr output when acting as a filter, e.g.
 #
 #   tidy_pt_wrapper < some.pt
 #
 # When run like this, it omits errors and warnings from tidy-html5 output
 # related to:
 #
 # - "<(metal|tal):.*?> is not recognized!" errors
 #
 # - warnings about proprietary "tal:" and "metal:" namespace attributes
 #
 # - warnings about discarding unexpected <tal:foo>, </tal:foo> / <metal:foo>,
 #   </metal:foo>
 #
 # - warning about missing DOCTYPE declaration
 #
 # - warning "inserting implicit <body>"
 #
 # - warning "inserting missing 'title' element"
 #
 # It preserves all other errors and warnings.
 #
 # Configuration for Sublime Text 2:
 #
 # Add this command as ``tidy_pt_wrapper`` to your $PATH
 #
 # Edit Preferences -> Package Settings -> SublimeLinter -> Settings: User
 #
 # Add this key to the dictionary there:
 #
 #    "sublimelinter_executable_map": {"html":"tidy_pt_wrapper"}
