Here's a completely rewritten version of NR 4.4.1 Vertical spacing inside a system Comments? Thanks. - Mark

Mark, I think this is a great start, and will greatly help. The major issues I see are (1) repeating information (i.e. the meanings of space, minimum-distance, padding, and stretchability), and (2) introducing exhaustive lists into the NR. Repeating information is prohibited by policy because it becomes very difficult to keep two parallel sections in synch. Exhaustive lists belong in the IR, instead of the NR. THat way they are automatically updated. Other than that, I have some editorial comments. Great work! Thanks, Carl http://codereview.appspot.com/2642043/diff/1/Documentation/notation/spacing.i...

The original "non-staff lines" is still better than "non-staff contexts" (which can imply Voice and Score), but "non-staff lines" reads like "the opposite of staff lines", which is confusing. I suppose defining the term clearly at the top will help.

I'd prefer to just change the previous sentence to: "Each of these context types uses a slightly different method for specifying the vertical spacing, which will be explained below." Did you really get lost while you were waiting? And do users really need to know that different contexts create different grobs? Wouldn't that be "talking through the code" a little too much? Also, even though staff-group contexts don't create the VerticalAxisGroup grob, their constituent staves do, and this in turn influences their spacing.

One argument for an exhaustive list would be that it's just good to know that FretBoards and FiguredBass are "non-staff lines" with spacing that's just as customizable as Lyrics. Perhaps the ideal solution is to include a sentence in each of the sections that describe these contexts, such as: "For purposes of vertical spacing, FigureBass contexts are considered non-staff lines. See `Spacing of non-staff lines'." But I still like the appearance of FretBoards and the others alongside Lyrics and ChordNames. What if I just say: "Examples of non-staff lines include: ChordNames, Dynamics, FiguredBass, FretBoards, Lyrics, and NoteNames." That way, if a context is added to the code base later, it doesn't invalidate the sentence, since it doesn't claim to be exhaustive. http://codereview.appspot.com/2642043/diff/1/Documentation/notation/spacing.i...

Um, I don't want to scare anyone, but I'll be proposing some name changes for these properties, too. And I currently prefer "non-staff lines" over "loose line contexts". But let's not get into that just yet.

I don't think it's confusing at all. staff contexts are contexts that are displayed in a staff. staff-group contexts are contexts that are displayed in a group of staves non-staff contexts are contexts that are displayed in something besides a staff. Voice is a context that is displayed in a staff. Score is not displayed in anything, as far as this is concerned. Also, we're not talking about non-Staff contexts, we're talking about non-staff contexts. The capital letter is important (and it can be explained here if we need to). http://codereview.appspot.com/2642043/diff/1/Documentation/notation/spacing.i...

You tell me about three different kinds of contexts, then you go talk about the different spacing properties in terms of Grobs -- VerticalAxisGroup and StaffGrouper. But I don't know what those mean in terms of staff-group, staff, and non-staff contexts that you've already explained. It's not until line 1746 (240 lines, or 4 pages + later) that you explain that VerticalAxisGroup properties apply to ungrouped staff contexts, and so forth. If you're going to tell me about the three kinds of contexts, give me some clues so I can understand the next stuff I'm reading. > Also, even though staff-group > contexts don't create the VerticalAxisGroup grob, their > constituent staves do, and this in turn influences their > spacing. I think your suggestion might be a little > misleading. No, because later on you describe the full spacing algorithm. The VerticalAxisGroup properties control the spacing of individual staves. The StaffGrouper properties control the spacing of groups of staves. http://codereview.appspot.com/2642043/diff/1/Documentation/notation/spacing.i...

But if you're starting from a big number, and trying to squeeze it down, (which is what we're doing), then I think the "minimum allowable" is more descriptive.

THat would be better. It would be even better if we gave the user a clue as to how to find an exhaustive list in the IR, e.g. all contexts that create a VerticalAxisGroup but not a StaffSymbol (I'm not sure if this is the right criterion or not). http://codereview.appspot.com/2642043/diff/1/Documentation/notation/spacing.i...

We're talking about printed output, not internal objects, and it's the use of "contexts" that introduces the confusion. So I'd prefer to see the simpler "staves" or "staff lines", "staff groups", and "non-staff lines" throughout. http://codereview.appspot.com/2642043/diff/1/Documentation/notation/spacing.i...

That's what I meant, but based on your previous statement, I assume even that would be incorrect. In fact, this is clearly wrong, since the refpoints of the staves are the midlines, right? So is it centered between the skylines?

There are some situations where you might want to override this, so I'm not sure if the docs have such a blanket statement. The point is that all of the logic involving StaffGrouper and its spacing variables is contained in the default callback associated with next-staff-spacing (ly:axis-group-interface::calc-next-staff-spacing). If you override that default callback, you will disable that logic for the relevant staff. However (and this is the source of my original comment) you will not actually override any of the properties in StaffGrouper, as the following example demonstrates: \new StaffGroup << % The override doesn't change the value of anything in % StaffGrouper. You can see this because the original % value of between-staff-spacing is used for all staves % but the first. Also, you can't achieve this effect by % changing 'default-next-staff-spacing, which shows that it % is sometimes useful to override 'next-staff-spacing. \new Staff \with { \override VerticalAxisGroup #'next-staff-spacing #'space = #30 } { c'1 } \new Staff { c'1 } \new Staff { c'1 } >> The above is probably an excessively long explanation for the docs. I would suggest something like "...since setting it will prevent StaffGrouper variables (such as ...) from having any effect on the current staff." http://codereview.appspot.com/2642043/diff/1/Documentation/notation/spacing.i...

It is "centered" between refpoints in the sense that its desired position is for its refpoint to be exactly centered between the refpoints of the surrounding staves. But it may not achieve this desired position due to other constraints like collisions or minimum-distances.

Then, the non-staff lines are spaced between the staves." I say 'space required' to mean the hard distances of 'minimum-distance and 'padding, because the reader might not have seen these property names yet.

Here's the next patch set for the "Vertical spacing inside a system" doc stuff. I tried to address everything you guys mentioned; let me know what you think. One significant thing I did here was to remove the entire @subsection called "Vertical spacing between systems", since I don't think it was really doing anything. I guess I'm ready for the next round of reviews. Thanks. - Mark

Hi Mark, It's the first time I read your NR4 patches, so I may certainly have missed a few things. Your patch looks good, but I was a bit surprised by the overall writing style of NR4. This chapter looks odd to me, and somehow not on par NR1 and 2. It's obviously a whole chapter that hasn't been much affected by GDP -- but of course, I'm not advocating that your patch should rewrite the whole chapter! :) http://codereview.appspot.com/2642043/diff/14001/Documentation/notation/spaci...

I've limited my comments to just one :) I think we need to push this now and move on - we still have to change all the names, and a further review of the wording after that might suggest a few more tweaks. I'm sure more clarification will be necessary after users try to understand and use this, but we're now so familiar with it that it's impossible to anticipate the problems they might have.

Wow, this is almost done. New patch set uploaded. I've responded to some comments individually, and made a lot of small changes requested, but I want to call everyone's attention to the TODO on l.1504, regarding this clause: "the reference point of a non-staff line is its highest point." Keith points out that the refpoint for Lyrics seems to be the lowest point (or perhaps the baseline?). It would be nice if someone could clear this up (or figure it out). What are the actual reference points for each type of non-staff line (ChordNames, Dynamics, FiguredBass, FretBoards, Lyrics, and NoteNames). I'd like to fix this before pushing. Also, in an attempt to improve the examples, I made some changes. So feel free to look them over if you like. I know this is a lot longer than what's there now; hopefully that's more a reflection of the amount of information than any wordiness on my part. Thanks again to everyone reviewing this.
