Hi Gilberto,

the barline-interface has been changed quite heavily with 2.17.
Please reread
http://lilypond.org/doc/v2.17/Documentation/notation/bars#bar-lines
and shout again, if the problem persists.

If you rework a 2.16-file you should use convert-ly.

Cheers,

Hi Thomas,

Thank you very much for your answer, I didn't realize that the bar line interface was changed. Now I do understand why the bar lines were not appearing. But even after reading the page you recommended me, I still could not make the automatic repeat bar lines appear after \repeat volta 2 {music}; it shows only simple bar lines and I have to manually add bars such as ".|:", ":..:" and ":|.".

Can anyone help me to figure this out? By the way, it only happens when I use that snippet in the layout:

\layout {

  \context { \Score

    \remove "Timing_translator"

    \remove "Time_signature_engraver"

    \remove "Default_bar_line_engraver"

}

  \context { \Staff

    \consists "Timing_translator"

    \consists "Time_signature_engraver"

    \consists "Default_bar_line_engraver"

}

Thanks a lot!

Gilberto
