Label creation for filters

[Antiokh]

It's a great idea to have filters and labels, but sometimes I need to create a label.

In example, I have an RSS-post like:

The coolest event ever!

City: London
Price: 300$

And I don't want to create all-the cities before they mentioned in a RSS, I want to create them as labels when they are in the entry, assign the existing label or create new (and then assign).

It is possible, will respond in detail tomorrow.

Can you provide sample link to feed you want to process this way so that I can create sample filter?

Atom
RSS

I wanna catch the city and skills sections

OK. Here it is. I found some related bug in RSS Guard, but the feature works.

function filterMessage() {
  // Deal with country.
  var country_rx = msg.contents.match(/<b>Country<\/b>: ?([\w ]+)/);

  if (country_rx != null && country_rx.length > 0) {
    var country = country_rx[1];
    var country_lbl = msg.createLabelId(`Country: ${country}`);

    msg.assignLabel(country_lbl);
  }

  // Deal with skills.
  var skills_rx = msg.contents.match(/<b>Skills<\/b>: ?([-\w, .]+)/);

  if (skills_rx != null && skills_rx.length > 0) {
    var skills_all = skills_rx[1];
    var skills = skills_all.split(/,? {2,5}/);

    skills.forEach((skl) => {
      if (skl != null && skl.length > 0) {
        var skill_lbl = msg.createLabelId(`Skill: ${skl}`);
        msg.assignLabel(skill_lbl);
      }
    });
  }

  return MessageObject.Accept;
}

Thank you! I've tried this filter (added it and set corresponding feeds), but it doesn't work (I tried on Atom feeds it it's important).When I click "Test" on a filter it gives me the output: 

EXISTING articles filtering error: 'TypeError: Property 'createLabelId' of object MessageObject(0x7ffe33a5acf0) is not a function'. Article will be ACCEPTED. Output (modified) article is: Title = 'Year of Linux Desktop' URL = 'https://mynews.com/news/5' Author = 'Napoleon Bonaparte' Is read/important = 'no/yes' Created on = '1692484482785' Contents = '<p>Browsers usually insert quotation marks around the q element.</p><p>WWF's goal is to: <q>Build a future where people live in harmony with nature.</q></p>' RAW contents = '<entry><title>Year of Linux Desktop</title><link href="https://mynews.com/news/5" rel="alternate" type="text/html" title="Year of Linux Desktop"/><published>2023-08-19T22:34:42</published><author><name>Napoleon Bonaparte</name></author><updated>2023-08-19T22:34:42</updated><id>https://mynews.com/news/5</id><summary type="html">&lt;p&gt;Browsers usually insert quotation marks around the q element.&lt;/p&gt;&lt;p&gt;WWF's goal is to: &lt;q&gt;Build a future where people live in harmony with nature.&lt;/q&gt;&lt;/p&gt;</summary></entry>'

BTW, it would be nice to have an ability to select the item from the feed and use its content as a base for test command. UPD. I've noticed that my distribution of Ubuntu has RSS Guard 4.0.4. I'll update it and try again.

Thank you, now everything works fine. First time it created the duplicates for every tag, so I started from one RSS channel to create initial tags and added a duplicate filter from the standard ones. There was an issue where the ring bells every fetch, regardless if there are any new items, but it's gone in 4.5.
