mumano crashes on using django template variables as part of tag attribute's value

[Oleg Lomaka]

If I use django template variable as part of html tag's attribute's value, mumano crashes with following message:

mumamo-idle-set-major-mode: cb=1.html, err=(error Invalid search bound (wrong side of point))
or another
mumamo-fontify-region: Invalid search bound (wrong side of point)

I use 744 revision of nxhtml trunk, and emacs nightly build for 2010-12-19.

Few examples:
{% block content %}
  <script type="text/javascript" src="{{ STATIC_URL }}1.js" ></script>
                                      ^^^^^^^^^^^^^^^^^
{% endblock %}

another example
<img src="{{ STATIC_FILE }}1.jpg" ></img>
          ^^^^^^^^^^^^^^^^^

On this error, emacs buffer became completely uneditable and only I can do is to save the document and open in another editor.

Also I've attach screenshot to picture the issue.

Thanks Oleg, very useful examples. I think this catched a simple oversight in the code. Can you please try the new beta 2.09?

[Oleg Lomaka (olomix)]

Thank you for your help. The patch resolved the first example, but didn't resolve the second.

Now in case of this code "<img src="{{ STATIC_FILE }}1.jpg" ></img>" it generates following error "Making parse-sexp-lookup-properties buffer-local while locally let-bound!"

I've attached a screenshot.

I have tried to take care of the error message (this is actually just cosmetic in this case). However I am not sure what problem you have now. Can you please explain? (And perhaps update nXhtml beta again so we are not miscommunicating.)

[Oleg Lomaka (olomix)]

Ok, updated to r746.

Opened file with following content:
<img src="{{ STATIC_FILE }}1.jpg" />
<p>some text</p>

in *Messages* got this error:
(mumamo-major-mode-from-modespec): Couldn't find an available major mode for spec django-variable-mode

[lborgman (lennart-borgman)]

That should not happen. There is something wrong here. Can you please in the file buffer where you have this django code do

  M-: (emacs-Q-nxthml buffer-file-name)

That should start a new Emacs with just nXhtml loaded. Do you still see this error message in this new Emacs instance?

[Oleg Lomaka (olomix)]

After clean start, I don't see those error message, but the mode still doesn't work.

What did I do:
1. Start new emacs with such .emacs
(add-to-list 'load-path "~/.emacs.d/")
(load "~/.emacs.d/nxhtml-trunk/autostart.el")
(add-to-list 'auto-mode-alist '("\\.html$" . django-nxhtml-mumamo-mode))
In emacs.d only nxhtml-trunk
2. Run emacs-Q-nxhtml
3. Opened ~/3.html in new emacs instance with following content
{% block content %}
  <img src="{{ STATIC_URL }}1.jpg" />
  <p>some text</p>
{% endblock %}
4. Switched mode to django-nxhtml-mumamo-mode

Got the mode "nXhtml/django-nxhtml Invalid" when cursor placed somewhere inside {% block content %} tag except {{ STATIC_URL }} variable. When cursor outside {% block content %} the mode is "MuMaMo border/django-nxhtml". When the cursor inside {{ STATIC_URL }}, the mode is "Django variable/django-nxhtml"

The screenshot attached.

Thanks, this was a missing autoload. Should be fixed now in the latest beta 2.09.
