Limit on macro snippet size?

Limit on macro snippet size?

[Thomas S. Dye]

Aloha all,

I couldn't find any information on this in the manual or the mailing
list, though I vaguely recall some discussion on the list a while back.

Is there a limit on the length of text that a macro like this will
process?

#+MACRO: green \textcolor{PaleGreen4}{$1}

I have 2 and 3 line sections of text passed to $1 that worked last
spring, but fail now.

All the best,
Tom

Are you sure?  Here is a 3 line macro that seems to work fine for me:

  non-uniform acceptance ratio.  {{{note(Add note on RICH detectors
  relying on exactly this feature to discriminate between particle
  species.,inline)}}}

I have attached a screenshot of the relevant part of the output pdf to
show it actually works.  How does the failure happen, what do you see in
the exported file?

Hope this helps,

probably...  (others will answer, I'm sure)

Instead, I wonder whether it wouldn't just be easy enough to do:

#+begin_src org
  ,#+latex: \textcolor{PaleGreen4}{
  all of your text that can be several lines
  ,#+latex: }
#+end_src

Less fragile, so long as there are no paragraph breaks maybe...

But much less portable.

I think the limitation is that no newlines are allowed, but I did not
check the source.

Rasmus

Example:

     #+macro: identity foo-$1

     {{{identity(Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec iaculis orci nec nunc viverra dictum. Quisque interdum dolor metus, non consectetur velit pulvinar nec. Ut elementum, mi sed scelerisque convallis, sem neque euismod ligula, vel consectetur mauris massa quis magna. Morbi maximus ante ut justo placerat, in posuere nulla auctor. Sed dapibus eros et augue interdum, in eleifend libero tincidunt. Nunc tortor lorem, placerat non ultrices non, rutrum ut dui. Etiam quam ex, dictum in nunc id, aliquam blandit urna. Cras efficitur scelerisque erat in porta. Ut egestas scelerisque neque et elementum. Duis in ligula vel ante sodales dapibus dapibus fermentum mi. Nullam ipsum nunc, sodales eget felis eget, porttitor rutrum felis. Duis tincidunt lectus ut augue porttitor sol
 licitudin. Morbi sit amet nisl sodales, pulvinar dolor sollicitudin, placerat nisl. Integer non consectetur purus.)}}}


     {{{identity(a 
     b
     c
     d
     e
     f
     g
     h
     i
     j
     k
     l
     m)}}}

     {{{identity(a

     b)}}}

But it works with newlines for me; see my reply to the original message.

\textcolor{PaleGreen4}\{the only weapons they had were a
few stones in some of the Canoes and these they threw overboard
when they found they were not wanted\}.

Note the curly brackets are escaped.  Not sure why ...

Easy-peasy!  Org recognises the first {..} as part of a latex command,
not the later.  You need snippets.  I always use them to make export
more robust.  Try this:

#+macro: green @@l:\textcolor{PaleGreen4}{@@$1@@l:}@@

Hope this helps,

Btw, this happens because of the newlines of course :).

This doesn't work for me.  The latex output isn't marked up, but the
text passed to $1 appears in the tex file.


All the best,
Tom

Sorry, I have a shortcut for latex snippets to l.  Try replacing the l
with latex:

#+macro: green @@latex:\textcolor{PaleGreen4}{@@$1@@latex:}@@
