Hi,
I posted a question on emacs.stackexhcange.com about indenting in nxml-mode.
http://emacs.stackexchange.com/questions/24619/indent-continuation-lines-in-nxml-mode
My goal was to configure indenting to conform to the style guide described here.
https://www.freebsd.org/doc/en_US.ISO8859-1/books/fdp-primer/book.html#writing-style-guide
It seems this was not possible without some hacking.
I have given it a (very) preliminary attempt. I suspect there are cases I
haven't considered, but after some light testing, it seems to be working.
(defun nxml-compute-indent-from-matching-start-tag ()
"Compute the indent for a line using the matching start-tag."
(save-excursion
(back-to-indentation)
(nxml-token-after)
(let ((bol (point)) (bol-xmltok-type xmltok-type))
(and
(condition-case nil
(nxml-scan-element-backward
(point) t (- (point) nxml-end-tag-indent-scan-distance))
(nxml-scan-error nil))
(< xmltok-start bol)
(progn
(goto-char xmltok-start)
(skip-chars-backward " \t")
(bolp))
(if (memq bol-xmltok-type
'(data empty-element partial-start-tag start-tag ))
(+ (current-indentation) nxml-child-indent)
(current-indentation))))))
What problems am I missing?
