Hello! Currently I have these three lines at the start of my invoices:
#+BEGIN_EXAMPLE #+macro: invoice-no 11 #+date: 2016-06-01 #+title: Invoice #{{{invoice-no}}} #+END_EXAMPLE However, sometimes I forget to update the invoice number or date when copying the old invoice. Since I name my invoices in the format =NN_YYYY-mm-dd.org= I'm wondering if there's any way I can automatically populate the =invoice-no= and date macros by parsing the file name? I found the {{{input-file}}} macro, but I haven't been able to do anything useful with it. Any help appreciated! Stig
