Truncate Text In Lektor

In this example, variable post is an instance of Markdown. Snippet was tested with Jinja3 template engine. I use it for generating my blog entry previews.

{{ post.body.html | striptags | truncate(length=200, killwords=False, end='...') }}

• post.body.html: is the Lektor object containing regular string or HTML text.
• striptags: Removes all HTML markup and returns pure text. docs
• truncate(length=200, killwords=False, end='...'): truncate text to 200 symbols, stop at the nearest word that fits this length, and add "..." in the end of the truncated string. docs
