slur direction

[nbruley]

Though I'm not a music theory expert, it would seem to me that the slur here would be better going up. Is there a way to do that? One ABC reference seems to indicate that an apostrophe can be used to force the direction, but that doesn't work... ('EFG) I'm using abcjs-basic v6.2.2

I think, according to Gould, the slur is in the right direction but it should be outside the beam. The rules are complicated, which is why you are finding a lot of odd cases. If I can fix this particular case quickly I'll squeeze it into the next minor release.

[nbruley]

Would love to have the slur placement fixed as it will make our scores look much better; I recognize the programming for that is likely quite complicated.

[paulrosen]

This will be improved in version 6.4.0

[nbruley]

Thank you so much! It is certainly improved.

I know you didn't anticipate that it would solve all issues, but just a few comments:

1. Is there a way for me to space out the staves more so the words are not covered?

2. I don't understand why there would be a difference in the placement here...

The first is definitely a bug where the slur doesn't add to the height of the staff. I will take another pass at that.

The second is a mystery! I'll have to debug that.

[nbruley]

Doesn't look like the staff height is adjusted in version 6.4.2 yet... I will be patient :)

[paulrosen]

Sorry! I've had limited time lately so I decided I had to release what was ready.

[nbruley]

Understood! I appreciate all your efforts, particularly when you receive so little in return. Let me know how many hours you spend on these improvements.
