Re: [Orgmode] macros which expand to other macros

[Carsten Dominik]

Hi Daniel,

I have applied the patch, thanks.  I used the more restrictive version  
without

allowing partial macros.  Seems a bit wired to me.  Or can someone come
up with a compelling use case?

{{{uno}}} works (1) but {{{one}}} should also be 1, not {{…uno}}}


 I attach a patch [1] which adds support for macros which expand to  
other macros, so the previous examples would work.


 It would of course get locked if you wanted macros like #+MACRO:  
recu {{{recu}}}, but that's apparently the intended behaviour :-)


 It will even work for macros that create parts of other macros.

#+MACRO: cc1 11
#+MACRO: cc2 12
#+MACRO: mycc-start {{{cc
#+MACRO: mycc-end 2}}}
Yes, it is {{{mycc-start}}}{{{mycc-end}}}.
And even:
#+MACRO: mycc {{{mycc-start}}}{{{mycc-end}}}
{{{mycc}}}.

 (12 in both cases).
 If this is too complex, this partial macro writing can be  
disallowed by changing the (beginning-of-line) to a (goto-char  
(match-beginning 0)).
