Great job!
Really appreciate it!

Hello tablature users,

after sending my first version of a, I got a lot of positive resonse,
and a lot more of corrections/improvements. Thank you all!

Now, there is a (hopefully) better file which includes the following features/changes:

1) the palmmute/deadnote stuff is the same, only the code has been simplified, thanks to Neil's proposals

2) the \tabNumbersOnly settings are now the default, so when is included, the stems etc. are gone
 (as proposed by Grammostola Rosea)

3) the modern tab clef is now available as any other clef by typing \clef "moderntab"

To implement (3), there is another function necessary, which will be in future releases of lilypond, but
for now, you have to insert the following lines into scm/parser-clef.scm:

;; a function to add new clefs at runtime
(define-public (add-new-clef clef-name clef-glyph clef-position octavation c0-position)
 "Append the entries for a clef symbol to supported-clefs and c0-pitch-alist"
 (set! supported-clefs
      (acons clef-name (list clef-glyph clef-position octavation) supported-clefs))
 (set! c0-pitch-alist
      (acons clef-glyph c0-position c0-pitch-alist)))

Otherwise the new clef definition won't work.

Thanks again to Carl and Neil for their help!

There is one problem now with the settings in I simply made ties transparent, but
then, the fret number appears as it were a note to be played. Hopefully somewhere in the future,
I will find a possibility to let the fret number disappear, but as David Stocerk pointed out,
some cases had to be  distinguished (the following is a quote from a former posting from David):


It should be noted that a publishing standard is when there is a Note Staff + Tab Staff, tied notes (that is, the notes that are 'held') in the Tab Staff are indicated by parenthesizing the tab number(s). There are several conventions that are related to tied notes in a Notes+Tab situation:

 * Tab numbers that are 'tied to' are sometimes parenthesized,
   sometimes hidden.
 * In the case that 'tied to' notes are hidden, a parenthesized tab
   number is usually forced if the 'tied to' note is at the beginning
   of a line (i.e., the note is tied over a system break).
 * Likewise, parenthesized tab numbers are forced when a 'tied to'
   note begins a 2nd ending or Coda section.
 * A parenthesized chord in the Tab Staff are indicated with a single
   pair of parentheses surrounding all of the notes in the chord (as
   opposed to as single pair of parentheses around each individual
   note in the chord).


So this seems to be a difficult task, but somehow to manage.
