Radio target appears as a link in html export (in Emacs stable)

Radio target appears as a link in html export (in Emacs stable)

[H. Dieter Wilhelm]

Hello (),

when exporting radio targets to PDF they appear as normal text.
Sometimes I wish I could make them invisible but this is a behaviour I
can live with.

Anyway, when exporting to html the radio targets appear like a regular
link (technically I think they are a named anchor, something like <a
id="bla" name="bla">bla</a>).  The apperance is not helpful, only
confusing.  I guess I could change this behaviour with some css trickery
but it might become complicated, at least for my little html knowledge.

Is it possible in org to change the appearance of radio targets in html
exports without loosing their behaviour?

Thanks a lot, Org-mode version 8.2.10 (release_8.2.10 @
/usr/local/src/emacs-24.5/lisp/org/) from Emacs stable

                                     Dieter

You should use regular targets, then.

There are radio targets (e.g., <<<radio>>>) and radio links and (e.g.,
radio). The former are turned into anchors and the latter into links.
Don't you get the same?

But then I would have to turn all my radio links into proper links,
which I see no method - except with radio targets - to do this
automatically.

The radio links are turned correctly into links. :-)

But the targets (anchors) appear *also* as links (in HTML).  Which is
confusing and redundant because there are not linked to anything.

Here's an example:
http://duenenhof-wilhelm.de/dancing/date.html

E. g. _EDanceFever_ are links to their anchor below.

Maybe the following would be a good idea for org in general: A radio
target with an optional address argument like babel src blocks
<<<target>>>[http://targetaddresse.com] and upgrading the anchor to a
real, working link.

Thank you Nicolas

Instead of 

  <<<radio>>> ... radio

you would have to type

  <<radio>>   ... [[radio]]

which, IMO, is almost equally simple.

I'm confused, mainly because I'm not well versed in HTML. Let's consider
the following document:

  <<<radio>>> :target link: radio

When exporting it to HTML, I get the following:

  <a id="orgradiotarget1">radio</a> :target link: <a href="#orgradiotarget1">radio</a>

What would you expect instead?

Hmmm, that is true.  In the worst case I've to get used to it...

I'm getting <a id="orgradiotarget1" name="orgradiotarget1"</a> instead,
which *appears* in my html page as a link (which is wrong IMHO, Org-mode
version 8.2.10, Emacs stable).

I would expect an invisible html entity or just the apperance of the
text "orgradiotarget1".

Thanks

Actually, it is slightly more complicated:

  <<radio>> ... [[radio][radio]]

IIUC, the only difference with my output is the "name" attribute. You
may want to check `org-html-allow-name-attribute-in-anchors'.

The latter is indeed expected. 

Assuming the variable above is non-nil, which would explain your output,
we could consider to ignore it altogether for radio targets. Again, I'm
not much into HTML so I don't know if that's a good idea (e.g., is there
any use for an anchor with both an id and a name attribute in the
context of radio targets?).

Correcting myself,

What is really expected is to display the contents of the radio target,
without being a link.

Thanks for the confirmation

  org-html-allow-name-attribute-in-anchors is a variable defined in `ox-html.el'.
  Its value is t

Thanks, didn't know about this config. variable and it's working, the
anchor is then exported without a name...  But still appears as a link
in *my* html page :-(.  I conclude the problem is within the css file
I'm using for this particular site. (Please see the following comment)

I don't think so, with a simple org test file I'm getting the behaviour
you would expect - despite a named anchor - the target doesn't appear as
link, just a regular text.  Thank you very much, I have now a path to
look for.
