Re: Feature request - extended ties, addendum

[Steve D]

Hello Han-Wen, all--

Han-Wen, if you do decide to consider my previously mentioned 
feature request (if it seems like a worthy feature and feasible 
to you in terms of coding complexity, and worthy of your time 
when I'm sure there are many things that vie for your attention), 
I guess I ought to add a few comments to what I have already 
written about extended or deferred ties (in piano score notation, 
for example)--

Using this hypothetical construct:

\extendTies { c16~ e~ g~ } <c e g bes>4

It would be nice if the block that contains the notes the ties of 
which should be extended, were to be able to arbitrarily contain 
any of the following in addition to regular notes as shown in the 
example above (because all of the following can potentially 
appear in piano scores in examples of extended/deferred ties):

* grace notes
* tuples (triplets, etc.)
* chords

So, it would be nice if any of the following were possible:

\relative c' {
   \extendTies { \grace { c'16~ g'~ bes~ d~ e~ a~ } }
      <c,, g' bes d e a>4
}

\relative c' {
   \extendTies { c8~ g'~ \times 2/3 { bes8~ d~ e~ } }
      <c, g' bes d e a>2
}

\relative c' {
   \extendTies { <c e>8~ g' bes <d e a>~ }
      <c, e d' e a>2
}

Those are just hypothetical examples for your consideration, of 
course. As I mentioned previously, if you consider this a worthy 
addition to the already excellent and wonderful tool that 
LilyPond is, I am more than happy to pay for the feature, your 
time, effort and expertise. I have already received an email from 
another LilyPond user who also considers this a useful feature 
and is willing to contribute financially as well.

Thank you very much for your attention and consideration, and 
thank you for a great product that I am personally very grateful 
to be able to use.

Best regards,

Steve Doonan, New Mexico, US (UTC -7)
