\import help when gabc is involved

[Noah Lovins]

Hello all,

I am creating a liturgical booklet for our patron's feast day, and I have the office and mass files in separate directories. All my gabc and tex files for the office are in the `office` folder, but I'd like to insert the Mass into the booklet after terce, which is in a separate `mass` folder. I was able to use \import to get the tex file into the project, but it won't take the gabc files with it. It's saying the gabc files don't exist (they do, they're just in the `mass` folder). Does anyone have any ideas?

Thanks!

For me it works to keep all the gabc files in the project root. An imported Tex file always looks in the directory relative to the importing file, not the imported file. "Nested imports" are not too intuitive.

That seems really shady to not be able to work with sorted directories easily; our project is nearly 80 pages. I'd rather keep my files in their separate folders organized nice and properly. If things get complicated, so be it. Do you know how to work around it?

You just need to think carefully about how you write the import: eg maybe
write a macro that prepends the proper directory structure. It'll
probably take some trial and error to figure out what the working
directory is each time you include a score, but it shouldn't be too
complex. My guess is that in mass/index.tex you want to be loading
mass/score.gabc (including 'mass/').

Remember that LaTeX is basically doing a find-and-replace on your base
.tex file until all the backslashes are gone. It doesn't know that some
of the "replace" side of that came from a subdirectory. (I'm sure this is
an even grosser oversimplification than I think it is, but it helps me
think through file structures when working with LaTeX.)

(If you want to also be able to build mass/index.tex on its own, then you
probably need a more complex macro that checks a flag set in both
/index.tex and mass/index.tex.)

I haven't used gregorio in a while, but I did always keep the gabc in a
subdirectory, and it worked fine.

You can take a look at how https://github.com/Nocturnale-Romanum/nocturnale-romanum/ works, for an example of a very large project.

The subfile package is used to share headers among multiple tex files that can be built independently or collectively.

The gabc is in a subfolder (in this case, it's flat, but subfolders can be nested as needed).

In Christo,

Matthias

\import apparently can accept a path and filename but they appear to be different arguments? E.g. 

\import{Christmas}{Introit}

To include the file Introit.tex in subdirectory ./Christmas, where . is the location of your main Tex file. You could give a full path instead to be sure but generally relative paths are better for if you move things around.

Import has been modified so that the path no longer needs to end with \ but it used to.

See this link for some discussion on the topic:

I find texexchange to be very useful for Tex questions although they know nothing of Gregorio in general.
