Re: XML import (WAS: A premiere by Daahoud Salim, typeset with LilyPond)

[Jacques Menu Muzhic]

Hello Francisco,

- The converted code has \stemUp and \stemDown in every single note, which had to be searched and replaced. Also all articulations are forced up or down. 

Don’t know why musicxml2ly recently enforced such behavior, without any option to prevent it.

The same holds for \pointAndClickOff.

- Bar number checks have to be searched as well to delete them. What if you want to insert a measure? it's a nightmare. Even worse, bar number checks are not fixed strings, so you have to compose regular expressions to match them.

I’ve written a bash/awk script to offset measures numbers, leading to:

Copy/paste the LP snippet, type some carriage returns followed by Ctrl-d, and copy the result back into your LP code.

I guess Frescobaldi could provide such a tool to act upon the current text selection.

- Dynamics are not attached to the note it is meant to, if the author moved them with the mouse.

Do you mean they’re attached to a rest? I get that frequently after scanning with PhotoScore Ultimate and exporting to MusicXML. Or have you experienced a thoroughly different phenomenon?

- Just look at this converted block:

#(set-global-staff-size 20.6625714286)

\paper {
    paper-width = 21.59\cm
    paper-height = 27.93\cm
    top-margin = 1.27\cm
    bottom-margin = 1.27\cm
    left-margin = 2.53\cm
    right-margin = 1.27\cm
    between-system-space = 2.19\cm
    page-top-space = 1.27\cm
    indent = 1.66076923077\cm
    short-indent = 1.10717948718\cm
  }

No comments. Except that you have to pay attention to it even if you want to discard it completely, because it's between all else, otherwise useful, code. The work of picking and editing the useful parts is time-consuming.

The numerous decimal digits could easily be limited to 2 without a great loss IMHO. 

The various settings in \paper seem to come from the MusicXML data itself, and having them there makes it easy for the user to adapt them to what he needs.
