number of words vs number of chars about html-truncator HOT 8 CLOSED

Is this what you want?

HTML_Truncator.truncate("<p>Lorem ipsum dolor sit amet.</p>", 12, :length_in_chars => true)
# => "<p>Lorem ipsum …</p>"

from html-truncator.

Looks like it, yeah! That's an option already? I did not realize that, didn't notice it in docs anywhere.

I'll play around with it and see if it does what I want, and what Rails truncate does (truncate on word boundary most immediately prior to X chars -- not just force on exactly X chars even in the middle of a word!)

Yeah, it does look like that does exactly what I want!

Suggest advertising that api on the README, it wasn't clear to me it was available. (The api is also a little bit confusing, in that it's not clear it's going to go back to the immediately preceding word boundary (great), instead of just mechanically truncating exactly on X chars (would not be so useful)).

PPS: Rails goes further to let you specify the seperator, so you could truncate on "." instead to try to get the most sentances you can fit under X chars, etc. Although I can't recall if i've ever actually used that.

The example above is taken from the README, but you are right: I should explain that it won't truncate inside a word.

For the separator option, I don't think it's really useful. Maybe I'll add it if someone has good use case for it.

thanks for the gem! I will defintiely be using it for my future html truncating needs.

The example is actually not quite right in it's demo output, in a way that potentially encourages the wrong idea about the not-truncate-inside-a-word thing:

HTML_Truncator.truncate("<p>Lorem ipsum dolor sit amet.</p>", 12, :length_in_chars => true)
# => "<p>Lorem ipsum …</p>"

In the example there's a space after the ipsum but before the … -- in fact, HTML_Truncator will not include that space (great!) -- the example out is also exactly 12 characters, including the (incorrect) space -- this gives the impression that it really is truncating at exactly 12 chars, instead of the nearest preceding word boundary, as the sample output is consistent with that, not with what it actually does. A better example case might help, but a sentence explicitly saying it'll use nearest word boundary is prob still a good idea.

Thanks!

Yup, it's now in the README.
