Subject: [ANN] Incompatible change in (eval ...) macros
Date: Sun, 17 Dec 2017 09:46:27 +0100 [thread overview]
Message-ID: <87bmix68t8.fsf@nicolasgoaziou.fr> (raw)
Hello,
This is a heads-up about a small incompatible change in (eval ...)
macros. Here is the related ORG-NEWS entry:
Within =(eval ...)= macros, =$1=-like placeholders are always replaced
with a string. As a consequence, they must not be enclosed within
quotes. As an illustration, consider the following, now valid,
examples:
#+begin_example
,#+macro: join (eval (concat $1 $2))
,#+macro: sum (eval (+ (string-to-number $1) (string-to-number $2)))
{{{join(a,b)}}} => ab
{{{sum(1,2)}}} => 3
#+end_example
However, there is no change in non-eval macros:
#+begin_example
,#+macro: disp argument: $1
{{{disp(text)}}} => argument: text
#+end_example
This is necessary to fix an issue when the arguments of the macro
contain special characters (e.g., \ and ").
Regards,
