I am using Jinja2 to generate HTML files which are typically very huge in size. I noticed that the generated HTML had a lot of whitespace. Is there a pure-Python tool that I can use to minimize this HTML? When I say "minimize", I mean remove unnecessary whitespace from the HTML (much like Google does -- look at the source for google.com, for instance)
I don't want to rely on libraries/external-executables such as tidy for this.
For further clarification, there is virtually no JavaScript code. Only HTML content.
You might also investigate Jinja's built-in whitespace control, which might alleviate some of the need for manually removing whitespace after your templates have been rendered.
Quoting the docs:
But you can also strip whitespace in templates by hand. If you put an minus sign (-) to the start or end of an block (for example a for tag), a comment or variable expression you can remove the whitespaces after or before that block:
{% for item in seq -%}
{{ item }}
{%- endfor %}
This will yield all elements without whitespace between them. If seq was a list of numbers from 1 to 9 the output would be 123456789.
I found python slimmer library, perfect for what you need to do.
from slimmer import html_slimmer # or xhtml_slimmer, css_slimmer
html = html_slimmer(html)
