fancyhdr, multicols and gregoriotex problem

[Rob Leduc]

I'm having problems with headers in a file (mwe attached, although it is only as m as I could make it, since the problem is over a page break, and includes one short score).

The TL;dr - you'll see the problem from the MWE attached.  Probably insurmountable problems with multicols.  But if there is anything that can be done, or alternate packages to use, I'd love to know.

Details:

I expect based on what I've found is the problem is with the package multicols that does not handle floats, and that a general solution appears to be insurmountable for that package.  So there may be no fix to my problem with these packages, in which case recommendations of other packages or other paths to a formatting solution may be the only hope.  I'm going to also post at Stack Exchange since this may not really be a Gregorio Tex problem.  I suspect Gregorio just creates the float which multicols can't handle.  However, expertise here in possibly typesetting in similar formats may help me avoid the problem.

I'm trying to reproduce material in the style of the Nocturnale Romanum (e.g. https://gregobase.selapa.net/source.php?id=23&images=1&index=4  and ff.).  As we all know, such books often have many sections of partial pages of two column text, chants (probably floats? from gregorio tex).  I also want a header that I can change, preferably supplying my own text at each change, but if necessary built from section headings and the like.  The latter would require flexibility in order to match the original.

My problem is that at certain (but not all) page breaks, the multicols environment seems to screw up the fancy header, but only if there is a chant involved somewhere.  I understand LaTeX can start preparing material for the next page before assigning the location of a page break, and this is likely at the heart of it.

Compiling the attached example (currently linked to the gtex file for Stack Exchange purposes) will show the problem; changing the header by commenting out one line and uncommenting the other as indicated in mwe.tex will show without the problem.  It appears not enough horizontal line space is being allowed for the header, causing bad line breaks in the header and warnings about needing more space for the fancy header.

And yes, the formatting is hell because I've tried to distill it down to an MWE.  This obviously bears no relation to how I've actually formatted this.

Any help, be it suggestions of other packages or methods, or work arounds with these packages, or redefinitions of other items would be most appreciated.

Thank you!

For whatever reason, I can't seem to attach files - google just gives me an error on posting - so will have to post the text in the message body.

Actually, I may have to change my description a bit.

I've tried replacing the chant with a jpg picture of it created from Mac OSX grab tool, and I'm having a hard time replicating the problem.  So maybe it is related to Gregorio Tex's interaction with the LaTeX output routine, in terms of describing the size of the output image of the chant?

Chant is not output as an image or float in GregorioTeX they are paragraphs of (complicated) text. The words and neumes are fonts (which are put into boxes in order to get better control over the relative positioning). This allows us to make use of the automatic line breaking algorithms and let the chant adapt to the various page sizes.

I don’t think changing the header is solving the problem, so much as hiding it because the replacement header isn’t wide enough to force the header onto multiple lines. In fact, if I use either of the following headers (both of which force themselves to three lines):

\fancyhead[C]{Test \\ test \\ test}
\fancyhead[C]{Testing testing testing testing more testing more testing more testing more testing more testing\\ test}

The problem rears its head even with the score replaced by \rule{\textwidth}{0.56in}, so while GregorioTex certainly has an interaction here, I’m not sure it’s the root cause.

You might want to look deeper into how fancyhdr sets the relative widths of the three header components (left, right, and center) and how multicols might effect this.

On my system, as soon as \gregorioscore is commented out, the problem disappears. No problem with \rule. On the other hand, on my system I could add to the header as many words up to 4 characters each without problem. Every word longer than that gets hyphenated with a line break. So it seems like an hyphenation interference.

Thanks so much, Fr. Samuel and Olivier!

The culprit seems to be the latin option in the class statement.  Removing that fixes everything (if it doesn't break something else! :) )

Like a lot of rookies, I've grabbed too many bits of code from elsewhere and didn't pay much attention until something started not to work.  Perhaps this option is duplicative of the babel package and I can just do without.  But it's time to read some more package documentation, I think.

In any case, the main problem is likely hyphenation as Olivier said, and the latin option seems to be a linchpin, if not directly the culprit.

Thanks for the help!

It looks like I've "solved" this problem, in a way.  I've switched my multilanguage support from babel to the polyglossia package.  Polyglossia provides switches \disablehyphenation and \enablehyphenation.  Including these in my fancy header \fancyhead command, bracketing the header text, suppresses hyphenation in the header (only) and fully prevents the issue, while (hopefully) still retaining latin language and hyphenation support.

Obviously less than ideal from a programming standpoint, and there has to be a bug for someone's package somewhere.  But at least this works.

There appear to have been (in the past) difficulties with loading hyphenation patterns for Latin.  These threads are old and certainly can't represent the current state of affairs, but I am still trying to determine if my hyphenation rules are being loaded correctly.  See, for example,

Jan 2019, this forum:  https://github.com/gregorio-project/hyphen-la/issues/44

Dec 2019, GitHub for polyglossia:  https://github.com/plk/biblatex/issues/949

Very Very Old (June 2015):  Stack Exchange concerning polyglossia:  https://tex.stackexchange.com/questions/251367/latin-text-not-hyphenated-at-all-with-lualatex-and-polyglossia

[Rob Leduc]

The good folks at Stack Exchange LaTeX forum seem to have identified the guts of my problem, and it's possibly something involving a possible change to Gregoriotex for a future revision:

https://tex.stackexchange.com/questions/581013/lualatex-hyphenation-issue-in-fancyhdr-with-gregoriotex-and-multicols-latin-te/581022

Apparently, multicols sets \pretolerance to -1, while Gregoriotex sets a hyphen penalty of -200.  The combination results in fancyhdr wanting to hyphenate every single word in a centered header.  One suggestion to the developers of gregoriotex is to restore the hyphen penalty following completion of a score, although this alone might not be sufficient with scores that are multiple pages long, like a hymn or invitatory psalm setting.  It is also possible that the other packages should consider modifications. 

This is all beyond my simple understanding, and so I just pass it along here.

We already do this.
