Would it be possible to ignore newline characters or to substitute them to space in conversion?

craigsapp commented 4 years ago

There are three possible ways to fix the problem:

(1) the one you mention: convert the newline into a space

(2) preserve the newline as \n in the text, and this would be converted to <lb> in the conversion to MEI (I don't know if verovio handles this yet, but I would expect so). In the general case this is probably the best solution if already possible in verovio, otherwise I could implement (1) easily, and then later switch to (2).

(3) split the text into two separate text layouts. This would work almost the same as (2) and I currently do that manually in Humdrum data when I want multi-line text in verovio or musedata.

<lb/> works with MEI in Verovio:

There's also related problem with conversion of xml to humdrum. First example in this issue was created with MuseScore and slightly changed to achieve the way how Finale converts multiline text expressions. MuseScore by itself splits multiline texts into separate lines:

For the Humdrum to MEI conversion I will convert \n characters into <lb/> elements. I probably will not allow <lb> directly in Humdrum since XML has problems with angle brackets (so I convert angle brackets into &lt; and &gt;. In other words, I would not know if <xxx> is supposed to be displayed as literal text, or converted into an XML element.

For the MusicXML to Humdrum converter, I will convert such text:

        <direction-type>
          <words default-y="40.00" relative-x="-9.47" relative-y="2.71">note
</words>
          <words>with newline</words>

into note\nwith newline. There are a couple of possibilities. Probably if I see multiple <words> in the MusicXML <direction-type> I will assume they are separated by a newline. There is a newline in the data, but I do not know if that is triggering the newline in the notation, or if the multiple <words> are triggering the newline.... Typically space/newlines characters surrounding text in XML data is ignored, so perhaps the newline in the MusicXML data example is also being ignored.

If the newline character is removed, then the newline (and space) in the display in MuseScore is removed as well:

          <words>with newline</words>
        </direction-type>
      <staff>2</staff>
      </direction>

</words>
          <words>with newline</words>
        </direction-type>
      <staff>2</staff>
      </direction>

So whitespace around the text is important (usually ignored in XML data)
