Various indentation issues (eruby-html)

[Dmitry Gutov]

Like discussed previously in Rails on Emacs group.

Each example starts indented as I'd like it to be, then I move to various lines, press Tab, and observe the changes.

1 <a href="#" title="<%= abc(@zz) %>" class="image">
2 <%= image_tag (@zz.photos.first ? @zz.photos.first.image.url(:medium)
3 : '/images/no_photo.jpg')%>
4 </a>

I move point to line 2, press Tab, nothing happens (good). Move to
line 3, press Tab -> the text on line 2 gets un-indented by 2 spaces
(!!), and the minibuffer says "Do not know how to indent here (both
leaving and entering sub chunks)". No idea why.

1 <td>
2 <%= unless params[:abc_id]
3 link_to 'cdf', '#', class: "show_others"
4 end %>
5 </td>

Tab on line 2 -> no effect (ok), tab on line 3 -> it gets un-indented
by 4 spaces (very much not-okay). Tab on line 4 -> line 2 (!!!) gets
un-indented 2 spaces. What's up with that?

1 <li>
2 <%= f.label :fee %>:
3 <%= f.number_field :fee, :maxlength => 6 %> roubles.
4 </li>

This one's harder to reproduce. When I just paste it to the buffer, go to 2, press Tab, go to 3, press Tab, nothing changes.
But if I add a newline at the end of the buffer, move back to 3, press Tab, then it gets un-indented by 2 spaces. I tried this also with (emacs-Q-nxhtml), and while the buggy behavior is not 100% reliable, "add a newline, move back" scenario certainly helps.

Another problem I encountered while writing this: if I have one of the examples in the buffer, do C-x h (select all), and paste another from the system clipboard, thus deleting the previous buffer contents, delete the line numbers, and then press Tab to indent something, I get this:

Debugger entered--Lisp error: (wrong-type-argument overlayp nil)
  overlay-get(nil mumamo-prev-chunk)
  mumamo-indent-line-function-1(nil nil nil)
  mumamo-indent-line-function()
  indent-for-tab-command(nil)
  call-interactively(indent-for-tab-command nil nil)

The fontification is also broken in the pasted text.

Damn, the launchpad ate all my indentation-whitespace.
Anyway, I think it should be obvious how each example should be indented, and each example should start that way.

Thanks for the bug report, Dmitry. Are you using the latest source code from Launchpad?

[Dmitry Gutov (dgutov)]

Its was the latest at the time of our discussion. Should I update?

[lborgman (lennart-borgman)]

It is probably the same, but please do so we are sure.

[Dmitry Gutov (dgutov)]

I checked, it's the latest, revision 834.
