richtext.truncate for truncating one word at a time

[subsoap]

Would be a useful option

[britzl]

Hmm, good suggestion. Maybe add an option table as a third argument with an option to truncate full words/to word boundary:

richtext.truncate(words, length, { full_word = true }) -- option name?

[subsoap]

yes, settings table would work for this

@subsoap I need to discuss the design a bit more:

• If we add an option to truncate to full words, then if the result of a call to truncate() would result in a partial word, the function should remove that entire word right? Truncating "up" to include a full partial word is probably never something you'd like to do right?

Yes, you should "round down" the words"

Although when truncating full words the counter should probably be for the actual word count and not the character accounts, single words would be a single number in the total truncation value

[britzl]

Good point. This has been implemented and released in 5.9.0

[subsoap]

Multiple &zwsp; with no spaces between are considered a single word. Probably want them each to be considered their own word no matter what because otherwise defeats their purpose as a timer buffer without modifying formatting.

[britzl]

Good point. This is required when truncating per word.
