Subject: 24.3; html-mode incorrect indentation inside template syntax
Date: Sun, 06 Apr 2014 08:53:04 -0700

Create a test.html file. Use html-mode. Fill with the following
contents:

```
<table>
  <thead>
    <tr>
      {% for header in headers %}
	<th>{{ header.attr1 }}</th>
      <th>{{ header.attr2 }}</th>
      {% endfor %}
    </tr>
  </thead>
</table>
```

This is a mix of HTML and Django template syntax [0]. If you indent line
6 (<th>{{ header.attr2 }}</th>) I would expect the line to align itself
with the previous line (<th>{{ header.attr1 }}</th>). Instead it appears
to aligns itself with the "for" template tag or perhaps the <tr> plus an
offset. The final result after indenting line 6 is as it appears above.

The mode pony-tpl-mode [1] uses html-mode to calculate indentation when
then previous line looks like HTML and not special syntax. See my bug
report there: https://github.com/davidmiller/pony-mode/issues/81

This was reported 5 years ago, but unfortunately never got a reply at
the time.

I can reproduce this on current master, but I wonder if it makes sense
to make html-mode support Django template syntax.  Shouldn't there be
a separate (perhaps derived) mode for that?

Best regards,
Stefan Kangas

FWIW, searching online suggests one could use
django-nxhtml-mumamo-mode for Django templates.

MuMaMo has been dead for a while.

http://web-mode.org/ might be the best choice here.

If it is the right technical approach
someone could fix it up again.

mmm-mode is a similar package in GNU ELPA. Not sure if we have support 
for Django templates out of the box (it can be configured, though).

But web-mode is better for newbies.

No other comments within 4 weeks, so I think the decision is that we
don't want to support Django templates in html-mode.

The suggestion is as above, to use web-mode for this instead.

I'm consequently closing this bug report.  If anyone disagrees with
that, feel free to reopen the bug or simply reply to this email.
