Escaping to insert comments in exported text

Escaping to insert comments in exported text

[Suvayu Ali]

Hi Orgers,

I wanted to insert comments in the exported tex file for latex export.
Is there an standard way to do that? I found normal '%text' gets
exported as '\%text'. However I can export comments by putting
'%%text', it gets exported as '%\%text'.

Is there any other solutions out there?

Aloha Suvayu,

I'd be inclined to use #+LaTeX: %text

Alternatively (and perhaps more robustly with multiline comments) you  
could make certain to \usepackage{verbatim} and then use

#+BEGIN_COMMENT
text
#+END_COMMENT

following the example of block level markup here:

hth,
Tom

Both of those are much cleaner solutions! Thanks a lot. :)

[PATCH] Prefer matching line beginnings in org-export-latex-special-chars

[Lawrence Mitchell]

* lisp/org-latex.el (org-export-latex-special-chars): Fix regexp for
`single' special characters and ellipsis.

Repeated special characters are exported differently depending on
their position in the buffer.  A "&&" string at the start of a line is
exported as "&\&" whereas in the middle of a line you get "\&\&".  The
former is incorrect.  Fix this by matching the beginning of a line
before a character.  While we're at it, amalgamate the regexps for the
different special characters.

Although this feels like a potentially useful feature, I believe
it is a bug.  Doubled special characters are exported differently
depending on where they are on a line:

&& foo

=> &\& foo

whereas

foo &&

=> foo \&\&

This is because the regexp for finding special characters prefers
matching a character over the start of a line \\(.\\|^\\)\\(&\\)
will set (match-string 1) to & and (match-string 2) to & if &&
occurs at the start of a line, although the intention is that
(match-string 1) should be the empty line-start string and
(match-string 2) the first ampersand.  We can fix this by
changing the regexp to \\(^\\|.\\)\\(&\\) as in this patch.

Cheers,
Lawrence
