Hi,

Please keep the list copied, this way everyone can
answer and others can benefit from searching the list
archives in the future.

Here's a start:

\version "2.22.1"

\layout {
  \context {
    \Score
    \cadenzaOn
    % Print all bar numbers. See
    % http://lilypond.org/doc/v2.23/Documentation/notation/bars#bar-numbers
    \override BarNumber.break-visibility = #begin-of-line-invisible
    barNumberVisibility = #all-bar-numbers-visible
    % First tick number is 1, not 2.
    currentBarNumber = 0
    % The tick marks.
    \override BarLine.bar-extent = #'(2.5 . 3.5)
    % Center bar number on the ticks.
    \override BarNumber.self-alignment-X = \CENTER
  }
}

% Bar numbers are not automatically incremented at
% manual bar lines.
incrementBarNumber =
\context Score \applyContext
  #(lambda (context)
     (set! (ly:context-property context 'currentBarNumber)
           (1+ (ly:context-property context 'currentBarNumber))))

tick = {
  \bar "|"
  \incrementBarNumber
}

%%

\repeat unfold 10 {
  c'4 \tick 8[ 16 32] \tick 16[ 32.] \tick
}
Best,
Jean
