Bug Description

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?

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.)

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

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 (oleg-lomaka) wrote :

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.
