All the versions of Lilypond in the tree produce dodgy guitar tab showing spurious vertical lines above or below the finger indicators. This appears to be an upstream problem (I can also reproduce with the 2.12.x version in Ubuntu's 11.4 repos) and to have been fixed already in later versions of Lilypond - the versions in the portage tree are Jan 2009 & Jan 2010 releases. I have tested with small samples from the Lilypond documentation (see URL above) and get the bug shown on the first page of the attached PDF (Lilypond's default output is PDF). A user in the #lilypond IRC channel on irc.freenode tested the same sample and got good output - see page 2 of the attached PDF - using version 2.13.49. Note that Lilypond prints its version number in the footer of its output document. Bug 370273 is a request for a 2.14.x version to enter the Portage tree. I think that would squash this bug. Reproducible: Always Steps to Reproduce: \version "2.12.3" \new TabStaff \relative c' { a,8 a' <c e> a d,8 a' <d f> a } symbols = { \time 3/4 c4-.^"Allegro" d( e) f4-.\f g a^\fermata \mark \default c8_.\<\( c16 c~ c2\! c'2.\prall\) } \score { << \new Staff { \clef "G_8" \symbols } \new TabStaff { \symbols } >> }
Created attachment 278017 [details] Output from Lilypond showing the problem (PDF)
Have tested on Lilypond 2.14.1 compiled on the same system and it does indeed fix this issue. A dev might wish to make this bug depend on bug 370273 (a version-bump request for this package).
This is almost certainly fixed by lilypond-2.14.2 which is now in ~arch. Reopen if not.
