### Register Transforms ### This is interesting because we don't expect all transforms to be ### available on all platforms. To do this we allow things to fail at ### two levels ### 1) Imports ### If the import fails the module is removed from the list and ### will not be processed/registered ### 2) Registration ### A second phase happens when the loaded modules register method ### is called and this produces an instance that will used to ### implement the transform, if register needs to fail for now it ### should raise an ImportError as well (dumb, I know) from logging import DEBUG, ERROR from Products.PortalTransforms.utils import log from Products.PortalTransforms.libtransforms.utils import MissingBinary modules = [ 'st', # zopish 'rest', # docutils 'word_to_html', # uno, com, wvware 'safe_html', # extract and remove potentially harmful tags 'html_body', # extract only the contents of the tag 'html_to_text', # re based transform 'text_to_html', # wrap text in a verbatim env 'text_pre_to_html', # wrap text into a pre 'pdf_to_html', # sf.net/projects/pdftohtml 'pdf_to_text', # www.foolabs.com/xpdf 'rtf_to_html', # sf.net/projects/rtf-converter 'rtf_to_xml', # sf.net/projects/rtf2xml 'image_to_png', # transforms any image to a PNG image 'image_to_gif', # transforms any image to a GIF image 'image_to_jpeg', # transforms any image to a JPEG image 'image_to_pcx', # transforms any image to a PCX image 'image_to_ppm', # transforms any image to a PPM image 'image_to_tiff', # transforms any image to a TIFF image 'image_to_bmp', # transforms any image to a BMP image 'lynx_dump', # lynx -dump 'python', # python source files, no dependancies 'identity', # identity transform, no dependancies 'markdown_to_html', # markdown, depends on http://surfnet.dl.sourceforge.net/sourceforge/python-markdown/markdown-1-5.py 'textile_to_html',# textile, depends on PyTextile http://dom.eav.free.fr/python/textile-mirror-2.0.10.tar.gz ] g = globals() transforms = [] for m in modules: try: ns = __import__(m, g, g, None) transforms.append(ns.register()) except ImportError, e: msg = "Problem importing module %s : %s" % (m, e) log(msg, severity=ERROR) except MissingBinary, e: log(str(e), severity=DEBUG) except Exception, e: import traceback traceback.print_exc() log("Raised error %s for %s" % (e, m), severity=ERROR) def initialize(engine): for transform in transforms: engine.registerTransform(transform)
