Sample applications of the package +are tabular lists, serial letters, and charts. + +An alternative to |csvsimple-legacy| is the |datatool| package +which provides considerably more functions and allows sorting of data by \LaTeX. +|csvsimple-legacy| has a different approach for the user interface and +is deliberately restricted to some basic functions with fast +processing speed. + +Mind the following restrictions: +\begin{itemize} +\item Sorting is not supported directly but can be done + with external tools, see \Fullref{sec:Sorting}. +\item Values are expected to be comma separated, but the package + provides support for other separators, see \Fullref{sec:separators}. +\item Values are expected to be either not quoted or quoted with + curly braces |{}| of \TeX\ groups. Other quotes like doublequotes + are not supported directly, but can be achieved + with external tools, see \Fullref{sec:importeddata}. +\item Every data line is expected to contain the same amount of values. + Unfeasible data lines are silently ignored by default, but this can + be configured, see \Fullref{sec:consistency}. +\end{itemize} + + +\subsection{Loading the Package} +The package |csvsimple-legacy| loads the packages +|pgfkeys|, +|etoolbox|, +and |ifthen|. +|csvsimple-legacy| itself is loaded with \emph{one} of the following +alternatives inside the preamble: +\begin{dispListing} +\usepackage{csvsimple} + % or alternatively (not simultaneously!) +\usepackage[legacy]{csvsimple} + % or alternatively (not simultaneously!) +\usepackage{csvsimple-legacy} +\end{dispListing} + + +Not automatically loaded, but used for many examples are the packages +|longtable| +and +|booktabs|. + + +\clearpage +\subsection{First Steps} +Every line of a processable CSV file has to contain an identical amount of +comma\footnote{See \refKey{/csv/separator} for other separators than comma.} separated values. The curly braces |{}| of \TeX\ groups can be used +to mask a block which may contain commas not to be processed as separators. + +The first line of such a CSV file is usually but not necessarily a header line +which contains the identifiers for each column. + +%-- file embedded for simplicity -- +\begin{tcbverbatimwrite}{grade.csv} +name,givenname,matriculation,gender,grade +Maier,Hans,12345,m,1.0 +Huber,Anna,23456,f,2.3 +Weißbäck,Werner,34567,m,5.0 +Bauer,Maria,19202,f,3.3 +\end{tcbverbatimwrite} +%-- end embedded file -- + +\csvlisting{grade} + +\smallskip +The most simple way to display a CSV file in tabular form is the processing +with the \refCom{csvautotabular} command. + +\begin{dispExample} +\csvautotabular{grade.csv} +\end{dispExample} + + +Typically, one would use \refCom{csvreader} instead of |\csvautotabular| to +gain full control over the interpretation of the included data. + +In the following example, the entries of the header line are automatically +assigned to \TeX\ macros which may be used deliberately. + + +\begin{dispExample} +\begin{tabular}{|l|c|}\hline% +\bfseries Person & \bfseries Matr.~No. +\csvreader[head to column names]{grade.csv}{}% +{\\\givenname\ \name & \matriculation}% + \\\hline +\end{tabular} +\end{dispExample} + + +\clearpage +|\csvreader| is controlled by a plenty of options. For example, for table +applications line breaks are easily inserted by +\refKey{/csv/late after line}. This defines a macro execution just before +the following line. +Additionally, the assignment of columns to \TeX\ macros is shown in a non automated +way. + +\begin{dispExample} +\begin{tabular}{|r|l|c|}\hline% +& Person & Matr.~No.\\\hline\hline +\csvreader[late after line=\\\hline]% + {grade.csv}{name=\name,givenname=\firstname,matriculation=\matnumber}% + {\thecsvrow & \firstname~\name & \matnumber}% +\end{tabular} +\end{dispExample} + +\smallskip +An even more comfortable and preferrable way to create a table is setting +appropriate option keys. Note, that this gives you the possibility to create a +|pgfkeys| style which contains the whole table creation. + +\begin{dispExample} +\csvreader[tabular=|r|l|c|, + table head=\hline & Person & Matr.~No.\\\hline\hline, + late after line=\\\hline]% + {grade.csv}{name=\name,givenname=\firstname,matriculation=\matnumber}% + {\thecsvrow & \firstname~\name & \matnumber}% +\end{dispExample} + +\smallskip +The next example shows such a style definition with the convenience macro +\refCom{csvstyle}. Here, we see again the automated assignment of header +entries to column names by \refKey{/csv/head to column names}. +For this, the header entries have to be without spaces and special characters. +But you can always assign entries to canonical macro names by hand like in the examples +above. Here, we also add a \refKey{/csv/head to column names prefix} to avoid +macro name clashes. + +\begin{dispExample} +\csvstyle{myTableStyle}{tabular=|r|l|c|, + table head=\hline & Person & Matr.~No.\\\hline\hline, + late after line=\\\hline, + head to column names, + head to column names prefix=MY, + } + +\csvreader[myTableStyle]{grade.csv}{}% + {\thecsvrow & \MYgivenname~\MYname & \MYmatriculation}% +\end{dispExample} + + +\clearpage +Another way to address columns is to use their roman numbers. +The direct addressing is done by |\csvcoli|, |\csvcolii|, |\csvcoliii|, \ldots: + +\begin{dispExample} +\csvreader[tabular=|r|l|c|, + table head=\hline & Person & Matr.~No.\\\hline\hline, + late after line=\\\hline]% + {grade.csv}{}% + {\thecsvrow & \csvcolii~\csvcoli & \csvcoliii}% +\end{dispExample} + +\smallskip +And yet another method to assign macros to columns is to use arabic numbers +for the assignment: + +\begin{dispExample} +\csvreader[tabular=|r|l|c|, + table head=\hline & Person & Matr.~No.\\\hline\hline, + late after line=\\\hline]% + {grade.csv}{1=\name,2=\firstname,3=\matnumber}% + {\thecsvrow & \firstname~\name & \matnumber}% +\end{dispExample} + +\smallskip +For recurring applications, the |pgfkeys| syntax allows to create own styles +for a consistent and centralized design. The following example is easily +modified to obtain more or less option settings. + +\begin{dispExample} +\csvset{myStudentList/.style={% + tabular=|r|l|c|, + table head=\hline & Person & #1\\\hline\hline, + late after line=\\\hline, + column names={name=\name,givenname=\firstname} + }} + +\csvreader[myStudentList={Matr.~No.}]{grade.csv}{matriculation=\matnumber}% +{\thecsvrow & \firstname~\name & \matnumber}% +\hfill% +\csvreader[myStudentList={Grade}]{grade.csv}{grade=\grade}% +{\thecsvrow & \firstname~\name & \grade}% +\end{dispExample} + + +\clearpage +Alternatively, column names can be set by \refCom{csvnames} +and style definitions by \refCom{csvstyle}. +With this, the last example is rewritten as follows: + +\begin{dispExample} +\csvnames{myNames}{1=\name,2=\firstname,3=\matnumber,5=\grade} +\csvstyle{myStudentList}{tabular=|r|l|c|, + table head=\hline & Person & #1\\\hline\hline, + late after line=\\\hline, myNames} + +\csvreader[myStudentList={Matr.~No.}]{grade.csv}{}% +{\thecsvrow & \firstname~\name & \matnumber}% +\hfill% +\csvreader[myStudentList={Grade}]{grade.csv}{}% +{\thecsvrow & \firstname~\name & \grade}% +\end{dispExample} + +\smallskip +The data lines of a CSV file can also be filtered. In the following example, +a certificate is printed only for students with grade unequal to 5.0. + +\begin{dispExample} +\csvreader[filter not strcmp={\grade}{5.0}]% + {grade.csv}{1=\name,2=\firstname,3=\matnumber,4=\gender,5=\grade}% + {\begin{center}\Large\bfseries Certificate in Mathematics\end{center} + \large\ifcsvstrcmp{\gender}{f}{Ms.}{Mr.} + \firstname~\name, matriculation number \matnumber, has passed the test + in mathematics with grade \grade.\par\ldots\par + }% +\end{dispExample} + + +\clearpage +\section{Macros for the Processing of CSV Files}\label{sec:makros}% + +\begin{docCommand}{csvreader}{\oarg{options}\marg{file name}\marg{assignments}\marg{command list}} + |\csvreader| reads the file denoted by \meta{file name} line by line. + Every line of the file has to contain an identical amount of + comma separated values. The curly braces |{}| of \TeX\ groups can be used + to mask a block which may contain commas not to be processed as separators.\smallskip + + The first line of such a CSV file is by default but not necessarily + processed as a header line which contains the identifiers for each column. + The entries of this line can be used to give \meta{assignments} to \TeX\ macros + to address the columns. The number of entries of this first line + determines the accepted number of entries for all following lines. + Every line which contains a higher or lower number of entries is ignored + during standard processing.\smallskip + + The \meta{assignments} are given by key value pairs + \mbox{\meta{name}|=|\meta{macro}}. Here, \meta{name} is an entry from the + header line \emph{or} the arabic number of the addressed column. + \meta{macro} is some \TeX\ macro which gets the content of the addressed column.\smallskip + + The \meta{command list} is executed for every accepted data line. Inside the + \meta{command list} is applicable: + \begin{itemize} + \item \docAuxCommand{thecsvrow} or the counter |csvrow| which contains the number of the + current data line (starting with 1). + \item \docAuxCommand{csvcoli}, \docAuxCommand{csvcolii}, \docAuxCommand{csvcoliii}, \ldots, + which contain the contents of the column entries of the current data line. + Alternatively can be used: + \item \meta{macro} from the \meta{assignments} to have a logical + addressing of a column entry. + \end{itemize} + Note, that the \meta{command list} is allowed to contain |\par| and + that all macro definitions are made global to be used for table applications.\smallskip + + The processing of the given CSV file can be controlled by various + \meta{options} given as key value list.
