One Recipe, Multiple Feeds, Different Printer-Friendly Subs

[DTM]

Please help a newbie! I'm sure this must have been answered somewhere, but I can't find it.

I have a recipe that includes multiple feeds from a single source: it's a newspaper with a feed for "Headlines", another for "Editorials", and so forth. Getting the printer-friendly version for each feed is easy, you simply substitute "&template=printart" for a string in the url. But the string to replace is different for each feed. For one feed, all the articles have "/1478/rss", for another it's "/1016/rss05", etc.

I can get them to work for each feed individually, but how do I handle multiple substitutions within the same recipe?

In your print_version add an if elif else chain to find which url to modify, and change it.

Thanks!

I thought that was the way to go, but couldn't get it working. After another look at it, I got the syntax right, and that did it!

That's great.

And great it is!

After getting past that problem, the next issue turned out to be that the printer-friendly page was laid out with tables, which make my Nook gag. After a refresher course in regular expressions--have not used those since SunriseXP, years ago--I got around that. A couple more minor clean-up items, and I'll be golden!

I'll probably then submit that to wherever these things get submitted. (In case anyone is interested, it's the Detroit News.)

You can submit here - just note that you think it is ready for inclusion as a builtin. As to tables, you can regex them out of existence, but there are also some automatic table and style removal options for recipes.

That might be a better way to go. If they were to tweak their code, it might well break my regex. Where do I find that?

conversion_options¶
Recipe specific options to control the conversion of the downloaded content into an e-book. These will override any user or plugin specified values, so only use if absolutely necessary. For example:

    conversion_options = {
      'base_font_size'   : 16,
      'tags'             : 'mytag1,mytag2',
      'title'            : 'My Title',
      'linearize_tables' : True,
    }

no_stylesheets¶
Convenient flag to disable loading of stylesheets for websites that have overly complex stylesheets unsuitable for conversion to ebooks formats If True stylesheets are not downloaded and processed

no_stylesheets = True

remove_attributes¶
List of attributes to remove from all tags For example:

    remove_attributes = ['style', 'font']

OK, I'm using "no_stylesheets", and have looked at "remove_attributes", but had no idea what "linearize_tables" meant. I'll give it a try this evening.

It just removes the table, row and data tags so that the rows in the table are treated like lines (linearized) of text. You get all the data, and the advantages of automatic line breaks and reflow to fit a small screen, but you lose vertical alignment of different cells in the table.
