% This package was born to create fake elettrocardiograms, thanks to \TikZ package and \LaTeX3 bundle.
% \end{abstract}
% \tableofcontents
% \section{Introduction}
% To work correctly \textsf{ecgdraw} package are needed
% \begin{itemize}
% 	\item \TikZ package,
% 	\item \LaTeX3 bundle.
% \end{itemize}
%
%
% \section{Use}
%
% \begin{macro}{ecg}
% The package defined |ecg| environment with a optional argument \oarg{options}
% \begin{center}
% |\begin{ecg}| \oarg{options}
% ECG path
% |\end{ecg}|
% \end{center}
% where \meta{options} are \pkg{TikZ} keys. Inside the environment it's possible to draw a ECG thanks the |\ECG| macro
% \begin{center}
% |\ECG| \oarg{TikZ options} \parg{vertical position} \marg{ECG waves}
% \end{center}
% \end{macro}
% The macro have an optional argument \oarg{options}, that accepts Tikz options, an optional argument delimeted by brace \parg{vertical position}, vertical position of the path, and a mandatory argument \marg{ECG waves} which contain the list of ECG waves abbreviation.
%
% Each abbreviation is made of different part:
% \begin{center}
% |\ECG {| \oarg{options} \marg{wave name} \meta{other} |}|
% \end{center}
% \meta{options} aregiven to the single wave, \meta{wave name} is the abbreviation of the wave, while \meta{other} depends on the types of wave.
%
% \subsection{Waves}
% Different wave types are possible:
% \begin{macro}{p}
% |p| wave needs \meta{polarity} (allowed value |p|, |n|), wave height \meta{tenths of millivolts} (between 0.1-0.3 mV) and time \meta{milliseconds}.
% \begin{center}
% |p| \meta{polarity} |0| \meta{tenths of millivolts} \meta{milliseconds}
% \end{center}
% Bifasich wave with |d| and |b| polarity is needed a second wave
% \begin{center}
% |p| \meta{polarity} \meta{first tenths millivolts} \meta{second tenths millivolts} \meta{milliseconds}
% \end{center}
% \end{macro}
% \begin{macro}{q,r,s}
% Waves for QRS complex. Thei take as first argument wave height in millivolts and as second argument the duration in milliseconds.
% \begin{center}
% |q/r/s| \marg{wave height Q/R/S} \meta{milliseconds}
% \end{center}
% \end{macro}
% \begin{macro}{i}
% Isoelettric wave, take only one argument, which is time in \meta{milliseconds}.
%\begin{center}
%	|i| \meta{milliseconds}
%\end{center}
% \end{macro}
% \begin{macro}{t}
% First argument is \meta{polarity}, positive |p| or negative |n|, second argument is \meta{tenth of milliVolts}, as optional argument a correction if wave isn't simmetrical and last argument \meta{milliseconds}.
%\begin{center}
%	|t| \meta{polarity} \meta{tenth of milliVolts} \oarg{correction} \meta{milliseconds}
%\end{center}
% \end{macro}
% \begin{macro}{!}
% Allow to use a wave defined through |\newECG| macro.
%\begin{center}
%	|!| \meta{wave name}
%\end{center}
% \end{macro}
% \begin{macro}{?}
% Insert a label left to the path. Optional argument (default value |1 cm|) set horizontal shift.
%\begin{center}
%	|?| \oarg{horizontal shift} \meta{text}
%\end{center}
% \end{macro}
% \subsection{Options}
% \subsubsection{Grid}
% |ecg| environment accept different options to modify grid dimension.
% \begin{macro}{grid top}
% Accept a dimension as value. Grid is elarged toward top of the set value.
% \end{macro}
% \begin{macro}{grid bottom}
% Similar to |grid top|, but grid is enlarged toward bottom.
% \end{macro}
% \begin{macro}{grid left}
% Similar to |grid top|, but grid is enlarged toward left.
% \end{macro}
% \begin{macro}{grid right}
% Similar to |grid top|, but grid is enlarged toward right.
% \end{macro}
% \begin{macro}{grid border}
% Set bottom, top, left and right with the same \meta{value}.
% \end{macro}
% \subsection{Break ECG path}
% Sometimes ECG are too much wide and cannot fit the textwidth. So it's possible to allow \LaTeX{} to break ECG using the |breaklines| key.
% \begin{macro}{breaklines}\begin{macro}{breakindent}
% This key allow automate wrap ECG pattern. New line has an indent of |breakindent| value (default 1~cm).
% \end{macro}\end{macro}
% \subsection{ECG title}
% \begin{macro}{ECG title}\begin{macro}{ECG title align}
% I's possible to insert a ECG title by |ECG title| and set title align by |ECG title align| key (value |righ|, |left|, |center|).
% \end{macro}\end{macro}
% \subsection{Wave database}
% |\newECG| macro add a custom wave
% \begin{center}
% |\newECG| \marg{wave name} \marg{wave code}
% \end{center}
% It's possible to call \meta{wave name} inside |\ECG| using the key |!|.

% Definisco alcune chiavi da passare all'ambiente \env{ecg}.

Il booleano |\sk_ECG_breaklines_bool| serve per gestire i tracciati, abilitando o disabilitando la cesura automatica a fine riga.

% Nuovo booleano che permette di comprendere se siamo alla prima onda o no. Di base impostato su falso.
%    \begin{macrocode}
\bool_new:N \sk_ECG_start_bool
%    \end{macrocode}

% Viene definito il comando |\ECG| che prende due argomenti: uno opzionale |O{}| (che di default non ha nulla) e uno obbligatorio m. L'opzionale rappresenta le opzioni di \TikZ passate poi al comando |\draw[]| (come i comandi per il colore). L'obbligatorio invece Ã¨ la lista di onde che va poi processata
%    \begin{macrocode}
\DeclareDocumentCommand \ECG { O{} m }
  {
  \begin{tikzpicture}
  \coordinate(sk_end) at (0,0);
  \sk_ECG:nn { #1 } { #2 }
  \end{tikzpicture}
  }
%    \end{macrocode}

% Sempre analogo del comando |\ECG|, ma pensato per funzionare dentro all'ambiente ecg. Questa versioni infatti non apre ne chiude l'ambiente tikzpicture. Inoltre, oltre ai due precedenti comandi, si introduce il comando facoltativo racchiuso tra parentesi tonde, che permette di collocare il traccaito all'altezza voluta. Il sistema con |\sk_ECG_yshift_dim| toglie per ogni comando |\ECG| 2.5~cm in modo che il successivo comando (se non viene specificato un valore tra parentesi) sia collocato sotto il precedente.
%    \begin{macrocode}
\cs_set_nopar:Npn \sk_ECG_env:nnn #1 #2 #3
{
  \tl_if_empty:nTF { #2 }
      { \coordinate(sk_end) at (0,\sk_ECG_yshift_dim);  }
      { \coordinate(sk_end) at (#2); }
  \sk_ECG:nn { #1 } { #3 }
  \dim_set:Nn \sk_ECG_yshift_dim { \sk_ECG_yshift_dim - 2.5cm }
}
%    \end{macrocode}

% Definisco la dimensione per lo spostamento in verticale dei vari tracciati. Inoltre definisco due contatori per la numerazione di tutte le onde, uno per il tracciato e uno per l'onda.
%    \begin{macrocode}
\dim_new:N \sk_ECG_yshift_dim
\dim_new:N \sk_ECG_x_dim
\int_new:N \sk_ECG_row_int
\int_new:N \sk_ECG_wave_int
%    \end{macrocode}

% Ambiente \env{ecg}. Il suo scopo Ã¨ permettere di disegnare piÃ¹ tracciati, e collocarci dietro una griglia millimetrata. Inanzitutto azzero il valore dell'altezza per partire nuovamente da zero (non sarebbe necessario, ma per scrupolo Ã¨ meglio azzerare comunque). Imposto poi che il comando |\ECG| accetti un argomento opzionale tra parentesi quadre, uno opzionale tra tonde e uno obbligatorio. Passo tutto a |\sk_ECG_env:nnn|. Apro l'ambiente \env{tikzpicture}. La versione asteriscata non utilizza l'ambiente \env{center}.

%    \end{macrocode}

% L'ambiente \env{pgfonlayer} permette di selezionare su quale livello porre la nostra griglia millimetrata. AffinchÃ© si adatti automaticamente ai tracciati sfrutto un nodo di \pkg{TikZ} speciale: current bounding box, le cui dimensioni sono proprio le attuali dimensioni del disegno \pkg{TikZ}. Sfrutto quindi due ancore del nodo |current bounding box|: quella in altro a destra (ancora |north east|) e in basso a sinistra (ancora |south west|). Le chiavi |xshift| e |yshift| permettono di traslare il punto dei valori passati (quelli impostati con le varie chiavi |border|). In tal modo sono definiti due nodi |sk_start| e |sk_stop| che definiscono i vertici in alto a destra e in basso a sinistra della griglia, che sarÃ&nbsp; semplicemente disegnata con grid e i settaggi desiderati (colore e step). Il tutto, grazie all'ambiente \env{pfgonlayer}, posto automaticamente sullo sfondo.

%    \begin{macrocode}
\seq_new:N \sk_ECG_seq
%    \end{macrocode}

% Dopo aver svuotato la token listi delle onde e la sequence (e settato a vero il booleano di onda iniziale) si suddivide la lista di onde rispetto alle virgole (il secondo argomento di |\seq_set_split:Nnn|) e si salva nella sequence. Il comando |\seq_map_inline:Nn| passa poi ogni singolo elemento della sequence al suo argomento come |##1| (l'argomento |#1| sono le opzioni \env{TikZ}).
%    \begin{macrocode}
\cs_set_nopar:Npn \sk_ECG:nn #1 #2

  \seq_map_inline:Nn \sk_ECG_seq { \sk_ECG_use:w ##1 \q_nil { #1 } }

%    \end{macrocode}

% Macro che processa ogni singola onda: prende 4 argomenti.
% \begin{enumerate}
% \item Il primo opzionale sono eventuali opzioni per una singola onda (pensato principalemente per colorare una singola onda, magari per evidenziarla). Viene passato insieme a |#4| (che rappresenta le opzioni globali del tracciato), alle opzioni di |\draw|, che Ã¨ salvato nella token list |\sk_ECG_onda_tl|. Il comando |\draw| Ã¨ impostato con le chiavi osservabili. Lo shift pone il punto zero nell'ultimo node |sk_end|. Al termine, prima di espandere la token list (e rendere effettivo il disegno \pkg{TikZ}), si aggiorna la posizione del nodo |sk_end| e si chiude |\draw| con il punto e virgola necessario.
% \item Il secondo Ã¨ la prima lettera della sigla. Viene passato al comando |\str_case:nn| che lo confronta con tutte quelle presenti e usa quella che coincide con il codice corrente.
% \item Il terzo Ã¨ un argomento delimitato, ossia anche se non sono presenti tonde, il comando raccoglie tutto ciÃ² che trova fino al delimitatore (in questo caso il mark |\q_nil|). Permette di scrivere indipendentemente costrutti come |!{nome}| o |!nome| e ottenere il medesimo risultato. Il comando viene poi passato alle macro interne selezionate dalla prima lettera dell'onda.
