\section{Gregorio Controls}
These functions are the ones written by gregorio to the gtex file.
While one could, in theory, use/change them to alter the appearance of
elements of the score, it is far better to make your changes in the
gabc file and let gregorio make the changes to the gtex file.
\macroname{\textbackslash GreAnnotationLines}{\#1\#2}{gregoriotex-main.tex}
A wrapper macro for placing annotations above the initial. The
arguments are provided by the \texttt{gabc} file in the
\texttt{annotation} header field. This macro tests for the presence
of the annotation box which means that the annotation is explicitly
defined in the \texttt{main.tex} file. If so, this macro does nothing,
respecting the annotation value in the \texttt{main.tex} file.
\begin{argtable}
\#1 & string & First line text to place above the initial.\\
\#2 & string & Second line text to place above the initial.\\
\end{argtable}
\macroname{\textbackslash GreBeginScore}{\#1\#2\#3\#4\#5\#6\#7\#8}{gregoriotex-main.tex}
Macro to start a score.
\begin{argtable}
\#1 & string & a unique identifier for the score (currently an SHA-1-based digest of the gabc file)\\
\#2 & integer & the height number of the top pitch of the entire score, including signs\\
\#3 & integer & the height number of the bottom pitch of the entire score, including signs\\
\#4 & 0 & there is no translation line in the score\\
& 1 & there is a translation line somewhere in the score\\
\#5 & 0 & there is no above lines text in the score\\
& 1 & there is above lines text somewhere in the score\\
\#6 & string & the absolute filename of the gabc file if point-and-click is enabled\\
\#7 & integer & the number of staff lines\\
\#8 & \TeX\ code & macros to run before the score (\eg, setting clef
extrema)\\
\end{argtable}
\macroname{\textbackslash GreEndScore}{}{gregoriotex-main.tex}
Macro to end a score.
\macroname{\textbackslash GreBeginHeaders}{}{gregoriotex-main.tex}
Macro called at the beginning of a set of gabc headers.
\macroname{\textbackslash GreEndHeaders}{}{gregoriotex-main.tex}
Macro called at the end of a set of gabc headers.
\macroname{\textbackslash GreAccentus}{\#1\#2}{gregoriotex-signs.tex}
Macro for typesetting an accentus.
\begin{argtable}
\#1 & integer & height number of episema\\
\#2 & string & Type of glyph the episema is attached to. See \Nameref{NoteOffset} for a description of options.\\
\end{argtable}
\macroname{\textbackslash GreAdditionalLine}{\#1\#2\#3}{gregoriotex-signs.tex}
Macro to typeset the additional line above or below the staff.
\begin{argtable}
\#1 & string & See \Nameref{NoteOffset}.\\
\#2 & integer & The ambitus of the porrectus or porrectus flexus if the first references these glyph types; ignored otherwise.\\
\#3 & integer & Set horizontal episema (0), horizontal episema under a note (1), line at top of staff (2), line at bottom of staff (3), choral sign (4).\\
\end{argtable}
\macroname{\textbackslash GreAdHocSpaceEndOfElement}{\#1\#2\#3}{gregoriotex-main.tex}
Macro to end an element with an ad-hoc space.
\begin{argtable}
\#1 & float & The factor to scale the default space for use as an ad-hoc space.\\
\#2 & \texttt{0} & Space is breakable.\\
& \texttt{1} & Space is unbreakable.\\
\#3 & integer & The number of notes in the syllable prior to this macro.\\
\end{argtable}
\macroname{\textbackslash GreAugmentumDuplex}{\#1\#2\#3}{gregoriotex-signs.tex}
Macro for typesetting an augmentum duplex (a pair of punctum mora)
\begin{argtable}
\#1 & integer & Height number for first punctum mora.\\
\#2 & integer & Height number for second punctum mora.\\
\#3 & integer & First punctum mora occurs before last note of a podatus, prorectus, or toculus resupinus (1), or not (0).\\
\end{argtable}
\macroname{\textbackslash GreBarBrace}{\#1}{gregoriotex-signs.tex}
Macro for typesetting a bar brace.
\begin{argtable}
\#1 & string & Type of glyph the episema is attached to. See \Nameref{NoteOffset} for a description of options.\\

\macroname{\textbackslash GreBarSyllable}{\#1\#2\#3\#4\#5\#6\#7\#8\#9}{gregoriotex-syllable.tex}
Macro for typesetting a bar syllable.
\begin{argtable}
\#1 & \TeX\ code & macro setting syllable letters for the current syllable\\
\#2 & empty & reserved for future use\\
\#3 & \TeX\ control sequence & the control sequence to use for styling the hyphen\\
\#4 & \texttt{0} & this syllable is not the end of a word\\
& \texttt{1} & this syllable is the end of a word\\
\#5 & \TeX\ code & macros setting syllable letters for the next syllable\\
\#6 & string & the line, byte offset, and column address for textedit links when point-and-click is enabled\\
\#7 & pair of integers & a pair containing alignment type and alteration type of the next glyph\\
\#8 &\TeX\ code & other macros (translation, double text, etc.) that don't fit in the limitation of the number of arguments\\
\#9 & \TeX\ code & The bar line (usually a \textit{writebar} call).
\end{argtable}
\macroname{\textbackslash GreBarVEpisema}{\#1}{gregoriotex-signs.tex}
Macro to typeset a vertical episema on a bar.
\begin{argtable}
\#1 & string & Type of glyph the episema is attached to. See \Nameref{NoteOffset} for a description of options.\\
\end{argtable}
\macroname{\textbackslash GreBeginEUOUAE}{\#1}{gregoriotex-main.tex}
Macro to mark the beginning of a EUOUAE block. Alters spacings and prohibits a line break until the end of the block.

Macro to specify a text which is different from \verb=#1#2#3= (of \verb=\GreSyllable=). It is useful for styles, for instance with:
\par\medskip

we will have
\begin{latexcode}
#1 = \textit{f}

ligatures. In this example we should call \verb=\grefixedtext{\textit{ffj}}=.
