Hi,
I am porting my websites to the new exporter, finally. Much is very smooth. I do have a problem with macros:
* Macro definition
#+MACRO: thumbright #+ATTR_HTML: style="float:right;width:$1;margin:0px 20px 0px 20px;" \n [[./Content/$2/thumb.jpg]]
* Macro call
{{{thumbright(300px,Wiskunde)}}}
* This used to expand to
<img src="./Content/Wiskunde/thumb.jpg" style="float:right;width:300px;margin:0px 20px 0px 20px;" alt="./Content/Wiskunde/thumb.jpg" />
* But now it expands to nothing
I am sure I am missing something basic. Thanks!
- Carsten

OK, I see, this seems to be because the "\n" is no longer interpreted as a newline character upon macro expansion, so the entire text ends up in the ATTR_HTML line and is treated as a comment.
Is there a way to get what I meant?
Thanks

It seems to be coming from deep with emacs: if I create a buffer
with
x y z \ x y z
and evaluate (with point somewhere on that line)
(buffer-substring-no-properties (point-at-bol) (point-at-eol))
I get "x y z \\ x y z", so the backslash is escaped willy-nilly.
This happens in org-element-keyword-parser. I don't know if the
macro expansion would replace \n with a newline absent the extra
backslash, but I'm sure that its presence does not help any.

Even if I delete the extra backslash from the value of the macro
in org-macro-initialize-templates, the regexp fails to properly
match:
,----
| ;; Install buffer-local macros.
| (org-with-wide-buffer
| (goto-char (point-min))
| (while (re-search-forward "^[ \t]*#\\+MACRO:" nil t)
| (let ((element (org-element-at-point)))
| (when (eq (org-element-type element) 'keyword)
| (let ((value (org-element-property :value element)))
| (when (string-match "^\\(.*?\\)\\(?:\\s-+\\(.*\\)\\)?\\s-*$" value)
| (funcall set-template
| (cons (match-string 1 value)
| (or (match-string 2 value) "")))))))))
`----
OTOH, if I modify the cell argument inside set-template[fn:1] to get rid of
the extra backslash, the macro expansion happened as expected.
Nick
Footnotes:
[fn:1] This is obviously a gross hack, only meant as a debugging aid.
In fact, I didn't even code it up: I just stepped through the
thing with edebug and slammed the modified value into the cell
argument.

Macros have been downgraded a bit, as there was some overlapping with
Babel functionalities. In particular, they are meant to replace objects,
not elements, which means they cannot contain newline characters
anymore.
You can use a Babel block to generate the Org code you want. You can
also try the following macro, which will generate the HTML code you
want:
#+MACRO: thumbright @@html:<img src="./Content/$2/thumb.jpg" style="float:right;width:$1;margin:0px 20px 0px 20px;" alt="./Content/$2/thumb.jpg" />@@

Hello Nicolas,
thanks for your reply. I now remember this point of downgrading the macros and replacing complex macro calls with babel code. Thanks also for the easy work-around.
