This module provides some technical features that allow to extract text
from any chunk of HTML, without HTML tags or attributes. You can chose
either:

- To truncate the result by amount of words or characters.
- To append an ellipsis (or any character(s)) at the end of the result.

It can be used to easily generate excerpts.

Usage
=====

This module just adds a technical utility, but nothing for the end user.

If you are a developer and need this utility for your module, see these
examples and read the docs inside the code.

Python example:

::

   def some_method(self):
       # Get truncated text from an HTML field. It will 40 words and 100
       # characters at most, and will have "..." appended at the end if it
       # gets truncated.
       truncated_text = self.env["ir.fields.converter"].text_from_html(
           self.html_field, 40, 100, "...")

QWeb example:

::

   <t t-esc="env['ir.fields.converter'].text_from_html(doc.html_field)"/>

Known issues / Roadmap
======================

- An option could be added to try to respect the basic HTML tags inside
  the excerpt (``<b>``, ``<i>``, ``<p>``, etc.).
