Added [nocustos] to suppress an end-of-line custos at that point.

Fixes #1271.

None of the current tests fail, and I added a test for this feature.

Please review and merge if satisfactory.

I think it misses an entry into CHANGELOG, and maybe also in the gabc part of the documentation...

The [nocustos] thing can be applied to anything right? That's quite a good idea!

also, currently the test only tests [nocustos] on bars and breaks with custos on regular notes, maybe it could be mixed?

Apart from that, good job, thanks a lot!

[henryso]

It's unclear to me what you mean by "mixed". Would you please elaborate?

[henryso]

The gabc part of the documentation does not (unfortunately) currently describe the actual syntax of gabc and rather covers major features that have been added (relatively) recently. I don't think there's a good place in the current documentation to add something about this feature. I think it's OK to leave it out until we do finally document the syntax.

[eroux]

Well, I think it's necessary to document it somewhere, and enven though the gabc part of the pdf is not really the best place, at least it's somewhere. When someone will compile a gabc documentation, he'll take this as a reference (among other things), and so he'll document [nocustos], so I think it's helpful to put it there, even though it won't be very useful right now... What do you think?

About mixed, something like

foo... (::[nocustos]) line break
bar... (::) line break with custos
foo... (a[nocustos]b) line break between a and b
bar... (ab) same
foo... (a[nocustos]) (b)
bar... (a) (b)

[henryso]

In trying to get (a[nocustos]b) to work, I have noticed that GregorioTeX is very willing to push the b past the end of the staff (and this happens even if not using [nocustos] at all):

I'm not sure what's going on here or how to fix it.

[eroux]

well, without the actual gabc code it's difficult to debug, but you can leave it for another issue if there's something wrong, we can merge this one before...

[henryso]

I added these "mixed" tests, and you can see the weird pushing past the margin that I mentioned above. Do you have any ideas how I might be able to fix it?

[eroux]

Hmmm I don't know, maybe the very long texts are too twisted for Gregorio to handle... maybe the most simple solution is to just remove them....

[henryso]

I adjusted the test to look nice (and also test the cases you wanted tested). However, if I touch it in certain ways, like removing a g from the ...f f f f[nocustos] g g g... sequence, it will again push past the end of the staff.

I still have to work on the documentation.

[henryso]

Documentation is in and (I think) the tests are complete. Please review.

[eroux]

Looks perfect, thanks a lot!
