Filtering

[guyfedwards]

Newsboat does a lot but I've not worked out how to show tagged/starred articles by category, only by feed... Would love that feature and the ability to sync with Tiny Tiny RSS...

Add searching by text in list, also by source, category.

Options:

• foo narrows by title
• foo category:allfoos narrows by title within category

Filtering by title added in #v2.0.0

@guyfedwards I'd love to help contribute this feature (namely, the filtering by feed name), as I use nom quite often.

Some thoughts I'd like to run by you. Glancing through the code for charmbracelet/bubbles/list, it seems that the main way I could see this working is by overriding the default FilterFunc on the list. For example:

func CustomFilter(term string, targets []string) []list.Rank {
      // split term into FeedName and Title, exclude targets that don't include FeedName

/*    This is the default code, copied from bubbles/list
	ranks := fuzzy.Find(term, targets)
	sort.Stable(ranks)
	result := make([]list.Rank, len(ranks))
	for i, r := range ranks {
		result[i] = list.Rank{
			Index:          r.Index,
			MatchedIndexes: r.MatchedIndexes,
		}
	}
*/

	return result
}

// in initialization
l := list.New()
l.Filter = CustomFilter

And then changing the TUIItem.FilterValue() to also include the string for the FeedName:

func (i TUIItem) FilterValue() { return i.FeedName + "some_delimiter" + i.Title }

This is using the standard bubbles/list functionality. I'd definitely like to hear your thoughts on this, and if there are any other filters you really want to add, or if you'd like this to be the primary one.

Thanks for all your hard work!

Hey @kanielrkirby, yea that's along the same lines I was thinking. Would be happy to review anything if you want to implement.

The initial functionality can just be a text search and later down the line add categories etc once the core function is fleshed out.
