# gly Writer-friendly Gregorian notation format compiling to gabc. *GLY* is an acronym of "Gregorio for liLYponders" or "Gregorio with separate LYrics. ## Why One of the most popular solutions for typesetting quadratic notation used for the Gregorian chant is [Gregorio][gregorio]. However, I have several objections against it's input format. That led me to designing an alternative, Gregorio-inspired notation format, which compiles to pure Gregorio GABC (which I don't like writing manually). ## Features * music separated from lyrics * no need of the ubiquitous and tedious parentheses * separation of "material and form" -> easy copying of the music or lyrics alone is possible (useful for a composer) * syllabified lyrics entered in a format inspired by LilyPond * music and lyrics can be interspersed as needed * no semicolons in the header * custom header fields supported (commented out in the GABC output; as gregorio crashes on headers it doesn't know) * several scores per file (when compiled to gabc, each becomes a separate file) * compile pdf preview by a single command, without writing any (La)TeX ## Examples Typical GABC source of an antiphon looks like this: name: Nativitas gloriosae; office-part: laudes, 1. ant.; occasion: In Nativitate B. Mariae Virginis; book: Antiphonale Romanum 1912, pg. 704; mode: 8; initial-style: 1; %% (c4) NA(g)TI(g)VI(g)TAS(gd) glo(f)ri(gh)ó(g)sae(g) * (,) Vír(g)gi(g)nis(hi) Ma(gh)rí(gf)ae,(f) (;) ex(f) sé(g)mi(h)ne(h) A(hiwji)bra(hg)hae,(g) (;) or(gh~)tae(g) de(g) tri(g)bu(fe/fgf) Ju(d)da,(d) (;) cla(df!gh)ra(g) ex(f) stir(hg~)pe(hi) Da(h)vid.(g) (::) Corresponding GLY may look like this: name: Nativitas gloriosae office-part: laudes, 1. ant. occasion: In Nativitate B.

Or, with music and lyrics interlaced: name: Nativitas gloriosae office-part: laudes, 1. ant. occasion: In Nativitate B.

Other arrangements are also possible. Order of music and lyrics is actually ignored during processing. ## Usage This gem provides executable `gly`. Run `gly help` for full list of subcommands. The most important ones are: `gly gabc FILE1 ...` converts given gly file(s) to one or more gabc files (one per score, i.e. one gly may spawn a bunch of gabcs). `gly preview FILE1 ...` Attempts to create a pdf document with all scores contained in each gly file. Expects gregorio and lualatex to be in PATH and gregoriotex to be installed and accessible by lualatex. ## Tools [Emacs mode with syntax highlighting for gly][elisp]  ## Run tests by executing `tests/run.rb` ## License MIT [gregorio]: https://github.com/gregorio-project/gregorio [elisp]: /tree/master/elisp
