When i truncate my text it just remove the img tag:

`

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed sed rhoncus mauris. Pellentesque tempus, sapien sit amet volutpat tristique, felis lectus rhoncus sem, ut laoreet velit nisi ac turpis.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed sed rhoncus mauris. Pellentesque tempus, sapien sit amet volutpat tristique, felis lectus rhoncus sem, ut laoreet velit nisi ac turpis.

Any interest in making API similar to rails truncate? You tell it the max number of chars, instead of max number of words. But you can also tell it the separator to use, for instance ' ', to make sure it truncates on word boundary -- it'll truncate at the first separator before the limit.

My concern with truncating on number of words, is if the input has a really long 'word', hundreds of chars without any spaces -- nothing will get truncated.

Am I wrong in assuming that you are modifying the way that Nokogiri's built-in classes work for all code that is calling into Nokogiri? Thus making this unusable in large projects that already depend on Nokogiri?

First of all thanks for this awesome gem, I'm really happy with it! It's just what I needed. But I found a case where I need a fixed character length. Would it be possible for you to consider adding an option for character length as an extra option?

To search words and count in text node you use pattern like this

Suppose we have a blog with images and texts, we wanna truncate the blog as thumbnail in blog list, but we don't want images.

Seems the gem hasn't support it?

Thanks for any help.

Just stumbled at this:

HTML_Truncator.truncate('12345678901', 10, length_in_chars: true)
=> "1234567890…" # good

HTML_Truncator.truncate('<br>12345678901', 10, length_in_chars: true)
=> "<br>1234567890…" # good

HTML_Truncator.truncate('<br>&lt;br&gt;12345678901', 10, length_in_chars: true)
=> "<br><br>123456…" # bad, second '<br>' is decoded!

HTML_Truncator.truncate('&lt;br&gt;', 10, length_in_chars: true)
=> "&lt;br&gt;" # inconsistent: if length is shorter, it is not decoded as opposed to example before

I think the method should never decode strings. The encoded chars could count as 1 length (< is length 1 etc), so:

HTML_Truncator.truncate('<br>&lt;br&gt;12345678901', 10, length_in_chars: true)
=> "<br>&lt;br&gt;123456…"

This would make most sense I think.

I truncate some text with comma and recieve result: 'some long text,...'
So, i would like to remove that comma after text too
Can you add this feature?

I am already using Nokogiri for processing HTML, and it would be more efficient if I could just pass in a node to your sanitizer, instead of outputting to HTML, then having your library re-convert it to a node.

This line:
eval "class <<str; def html_truncated?; #{opts[:was_truncated]} end end"

causes a singleton class to be returned which prevents the field from being serialized using Marshal (and therefore prevents it from being cached using dalli/memcached).

HTML_Truncator.truncate("<style>Lorem ipsum dolor sit amet.</style>", 3)
HTML_Truncator.truncate("<script>Lorem ipsum dolor sit amet.</script>", 3)

results in

<style></style>…

some tags should not be touched at all

For html like the following:

<p>
  five words in this paragraph
</p>
<p>
  some more text which will be truncated
</p>

Given the above html is stored in the html var:

HTML_Truncator.truncate(html, 5)

returns html as follows:

<p>
  five words in this paragraph
</p>
<p>
  ...
</p>

Ideally I would expect the ... to be appended to the first <p> block, with the second block removed, like so:

<p>
  five words in this paragraph...
</p>

This looks like it could be a little bit of a pain to implement, sorry :3
