Subject: macros which expand to other macros

Message-ID: <87ab1d6nnl.fsf@gmail.com> (raw)


Hi.

  I want to include a note in several pages, therefore I created a #+MACRO for it. The macro must say „This file is best viewed when you open file {{{input-file}}} in org-mode (Emacs).“, where {{{input-file}}} would be expanded to the name of the file being expanded.
  Then I noticed that macros can't expand to other macros. This means:

#+MACRO: uno 1
#+MACRO: one {{{uno}}}
{{{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 100001
#+MACRO: cc2 100002
#+MACRO: mycc-start {{{cc
#+MACRO: mycc-end 2}}}
Yes, it is {{{mycc-start}}}{{{mycc-end}}}.
And even:
#+MACRO: mycc {{{mycc-start}}}{{{mycc-end}}}
{{{mycc}}}.

  (100002 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)).
