Lilypond manuals expect a fair bit of assumption. The first assumption
is that everyone reads the entire manual. (I don't think I'll ever
read chapter 6). The second assumption is that you read the code and
try and deduce what it does.
Two persons here (myself included) posted this exact snippet from the
manuals:
http://kainhofer.com/~lilypond/Documentation/user/lilypond/Bar-numbers.html#Bar-numbers
% Print a bar number every second measure
\set Score.barNumberVisibility = #(every-nth-bar-number-visible 2)
Reading that, there are some assumptions: the reader knows what a
comment is; the reader has read the entire section of the
documentation that this snippet is in. It's actually not that
difficult to understand (if you have no difficulties understanding
english.)
The first line tells you what's happening: instructions on how to
print a bar number every 2 measures. The second line is what would
need to be entered in order to do that. There are times when I see
scheme code or functions in lilypond that I really don't understand,
but, I know what I want. In this case, you want to show bar numbers
every five measures. Looking at the above snippet, there are two
explicit numbering words used: "second", in the first line, and "2" in
the second line. It would be safe to assume that the "2" in the second
line is what determines how often the bar numbers are shown. Even if
I'm not sure, I take the guess, copy/paste the code into my file
(using the lilypond code available on the website as a template for
where to place it) and change what I think would be correct to get the
results I want. Sometimes I'm successful, sometimes I'm not. If not, I
try two things.
First, I change the code in my file to give exactly the same output as
in the documentation. If that works, then I know I'm just changing the
wrong things, and I need to look for other examples to see the
differences in what's changed. If that doesn't work, then I copy the
exact snippet from the lilypond documentation into a new file and
beginning adding the things that are specific to my music until I get
a snippet that does what I want it to do. If that doesn't work, then I
have a minimal snippet that shows exactly what I'm trying to do, and
where it's failing, and I can post it here and ask questions.
I hope this helps you to understand reading the documentation and
adapting it to your personal use.
