9 I often find it useful to include a date on printed music, so that I
10 can see if I'm using the latest version, or tell someone else that he
11 should only use the version after a certain date. A simple solution is
12 to enter the date manually to the @code{.ly} file. But that's very
13 error prone. It's easy to forget updating the date. So i thought it
14 would be useful if you can add the date on which the PDF file is
15 generated automatically. I did't figure it out myself, but I asked on
16 lilypond-user mailing list. And guess what? Someone came with an
17 excellent solution! So thank you very much Toine Schreurs for sending
18 this solution to the user mailing list. I post it here for future
21 The solution is to use two scheme functions called @code{strftime} and
22 @code{localtime}, as shown in the snippet. It is a very flexible
23 solution, you can format the date just as you like it by adapting the
24 @code{\"%d-%m-%Y\"} string. See the Guile documentation for more
25 details on this format string: Formatting Calendar Time.
28 doctitle = "Adding the current date to a score"
31 % first, define a variable to hold the formatted date:
32 date = #(strftime "%d-%m-%Y" (localtime (current-time)))
34 % use it in the title block:
36 title = "Including the date!"
45 % and use it in a \markup block:
