Input of an exterior file into a gabc file

Somewhat related to my other question with subject: Conditional printing of sections of a gabc file (hopefully here: https://groups.google.com/g/gregorio-users/c/imaqnOZLPTU),
I wonder if there is a way to include an exterior file in processing along with an existing gabc file.

For example, responsories often end with the Gloria Patri.  Rather than continually retyping or cutting an pasting the Gloria Patri mode 8 into the scores that need it, could there be some form of input command (supporting paths) to include right in the gabc file to pull in an exterior gabc file containing this snippet? Maybe existing macro structure could work, but my grasp of this is tentative. 

Something like this?

Test.gabc
-------
name:responsory1;
def-m1:\gabcinput{gloria.patri.8}
%%
(c4) Here(g) is(g) my(g) chant(g) (::[em1]) 

gloria.patri.8.gabc
--------
name:Gloria Patri (Tone VIII);
%%
Glo(g)ry(h) ... etc. (::)

This doesn’t currently exist, but sounds like a reasonable feature request.

Thanks. I will look forward to it in the future, and likewise with the other feature.

Hello Fr. Springuel,

I wholeheartedly concur with Rob on both features, they would be very useful to any larger publishing project.

In Christo,

There is no need to extend gabc with logic constructs, as these are readily available from tools like the m4 macro processor, the C preprocessor, or various templating systems.
See an example of 1. a score with an optional part and 2. a score including a shared snippet, implemented using the C preprocessor.

Regards,
Jakub

Jakub,

This is interesting, and while I can almost understand the code, I am not a C programmer and so do not know anything about make, Makefile or how to run it with latex. 

Could you share the sequence of commands to prepare this example and produce the final pdf?

Thanks

Rob

Hello Rob,

If you have "make" (a standard build automation tool in Unix-like systems), "cpp" (the C preprocessor - most Linux distribution probably have it as a separate package, you will also automatically get it as a dependency when installing the "gcc" C compiler), gregorio and LuaLaTeX, the only command you need to execute is "make", which reads Makefile and executes the command sequence specified there. I.e. you don't "run make with latex", but rather "make" runs latex (and everything else needed to build the document, as specified in the Makefile) for you.

If you wanted to execute the command sequence without make, it would be as follows.

# 1. process C preprocessor directives, produce pure gabc
cpp -P salva_nos.gabc.cpp > salva_nos.gabc
cpp -P -DTEMPORE_PASCHALI salva_nos.gabc.cpp > salva_nos_paschal.gabc

cpp -P responsory.gabc.cpp > responsory.gabc

# 2. build the LaTeX document
lualatex example.tex

Regards,
Jakub

Jakub,

Thanks for this explanation.  It would appear that my older Mac is, in fact, missing cpp.  Research seems to suggest I install Apple Command Line Development Tools first, and I am too deep in the weeds to pursue this further.  This solution would work well, I think, for people who knew what they were doing.

Even smaller ones. I'm a novice user, but I constantly find myself reusing the same things or wanting to use one score file in different ways (with or without EUOUAE blocks, P.T. Alleluias, etc. ). and I'd have no idea how to do the other stuff, whereas I could make a macro work.
