Conditions may be imposed to exclude rows. %\item Determine whether an argument is an integer, a real number, %currency or a string. (Scientific notation is currently not %supported.) Locale dependent number settings are supported (such %as a comma as a decimal character and a full stop as a number %group character). %\item Convert locale dependent numbers/currency to the decimal %format required by the \sty{fp} package, enabling fixed point %arithmetic to be performed on elements of the database. %\item Names can be converted to initials. %\item Strings can be tested to determine if they are all %upper or lower case. %\item String comparisons (both case sensitive and case insensitive) %can be performed. %\end{itemize} % %The \sty{datapie} package can be used to convert a database into %a pie chart: %\begin{itemize} %\item Segments can be separated from the rest of the chart to make %them stand out. %\item Colour/grey scale options. %\item Predefined segment colours can be changed. %\item Hooks provided to add extra information to the chart %\end{itemize} % %The \sty{databar} package can be used to convert a database into %a bar chart: %\begin{itemize} %\item Colour/grey scale options. %\item Predefined bar colours can be changed. %\item Hooks provided to add extra information to the chart %\end{itemize} % %(The \sty{datapie} and \sty{databar} packages do not support the %creation of 3D charts, and I have no plans to implement them at any %later date. The use of 3D charts should be discouraged. They may look %pretty, but the purpose of a chart is to be informative. Three %dimensional graphics cause distortion, which can result in misleading %impressions. The \sty{pgf} manual provides a more in-depth %discussion on the matter.) % %The \sty{dataplot} package can be used to convert a database into %a two dimensional plot using markers and/or lines. Three dimensional %plots are currently not supported. % %The \sty{databib} package can be used to convert a \BibTeX\ database %into a \sty{datatool} database. % %\section{Data Types} %\label{sec:datatypes} % %The \sty{datatool} package recognises four data types: integers, %real numbers, currency and strings. % %\begin{description} %\item[Integers] An integer is a sequence of digits, optionally %groups of three digits may be separated by the number group character. %The default number group character is a comma (,) but may be %changed using \cs{DTLsetnumberchars} (see below). % %\item[Real Numbers] A real number is an integer followed by the %decimal character followed by one or more digits. The decimal %character is a full stop (.) by default. The number group %and decimal characters may be changed using %\begin{definition}[\DescribeMacro{\DTLsetnumberchars}]% %\cs{DTLsetnumberchars}\marg{number group character}\marg{decimal character} %\end{definition} %Note that scientific notation is not supported, and the number group %character may not be used after the decimal character. % %\item[Currency] A currency symbol followed by an integer or %real number is considered to be the currency data type. %There are two predefined currency symbols, "\$" and \cs{pounds}. %In addition, if any of the following commands are defined at the %start of the document, they are also considered to be a currency %symbol: \cs{texteuro}, \cs{textdollar}, \cs{textstirling}, %\cs{textyen}, \cs{textwon}, \cs{textcurrency}, \cs{euro} %and \cs{yen}. Additional currency symbols can be defined using %\begin{definition}[\DescribeMacro{\DTLnewcurrencysymbol}]% %\cs{DTLnewcurrencysymbol}\marg{symbol} %\end{definition} % %\item[Strings] Anything that doesn't belong to the above three %types is considered to be a string. % %\end{description} % %\subsection{Conditionals} %\label{sec:ifconditions} % %The following conditionals are provided by the \sty{datatool} %package: %\begin{definition}[\DescribeMacro{\DTLifint}]% %\cs{DTLifint}\marg{text}\marg{true part}\marg{false part} %\end{definition} %If \meta{text} is an integer then do \meta{true part}, otherwise %do \meta{false part}. For example %\begin{verbatim} %\DTLifint{2536}{integer}{not an integer} %\end{verbatim} %produces: %\DTLifint{2536}{integer}{not an integer}. % %The number group character may appear in the number, for example: %\begin{verbatim} %\DTLifint{2,536}{integer}{not an integer} %\end{verbatim} %produces: %\DTLifint{2,536}{integer}{not an integer}. %However, the number group character may only be followed by a group %of three digits. For example: %\begin{verbatim} %\DTLifint{2,5,3,6}{integer}{not an integer} %\end{verbatim} %produces: %\DTLifint{2,5,3,6}{integer}{not an integer}. %The number group character may be changed. For example: %\begin{verbatim} %\DTLsetnumberchars{.}{,}% %\DTLifint{2,536}{integer}{not an integer} %\end{verbatim} %this now produces: %\DTLsetnumberchars{.}{,}\relax %\DTLifint{2,536}{integer}{not an integer}, since 2,536 is now %a real number. % %Note that nothing else can be appended or prepended to the %number. For example: %\begin{verbatim} %\DTLsetnumberchars{,}{.}% %\DTLifint{2,536m}{integer}{not an integer} %\end{verbatim} %produces: %\DTLsetnumberchars{,}{.}\relax %\DTLifint{2,536m}{integer}{not an integer}. % %\begin{definition}[\DescribeMacro{\DTLifreal}]% %\cs{DTLifreal}\marg{text}\marg{true part}\marg{false part} %\end{definition} %If \meta{text} is a real number then do \meta{true part}, otherwise %do \meta{false part}. For example %\begin{verbatim} %\DTLifreal{1000.0}{real}{not real} %\end{verbatim} %produces: %\DTLifreal{1000.0}{real}{not real}. % %Note that an integer is not a real number: %\begin{verbatim} %\DTLifreal{1,000}{real}{not real} %\end{verbatim} %produces: %\DTLifreal{1,000}{real}{not real}. % %Whereas %\begin{verbatim} %\DTLifreal{1,000.0}{real}{not real} %\end{verbatim} %produces: %\DTLifreal{1,000.0}{real}{not real}. % %However %\begin{verbatim} %\DTLsetnumberchars{.}{,}% %\DTLifreal{1,000}{real}{not real} %\end{verbatim} %produces: %\DTLsetnumberchars{.}{,}\relax %\DTLifreal{1,000}{real}{not real} since the comma is now %the decimal character. % %Currency is not considered to be real: %\begin{verbatim} %\DTLsetnumberchars{,}{.}% %\DTLifreal{\$1.00}{real}{not real} %\end{verbatim} %produces: %\DTLsetnumberchars{,}{.}\relax %\DTLifreal{\$1.00}{real}{not real}. % %\begin{definition}[\DescribeMacro{\DTLifcurrency}]% %\cs{DTLifcurrency}\marg{text}\marg{true part}\marg{false part} %\end{definition} %If \meta{text} is currency, then do \meta{true part}, otherwise %do false part. For example: %\begin{verbatim} %\DTLifcurrency{\$5.99}{currency}{not currency} %\end{verbatim} %produces: %\DTLifcurrency{\$5.99}{currency}{not currency}. Similarly: %\begin{verbatim} %\DTLifcurrency{\pounds5.99}{currency}{not currency} %\end{verbatim} %produces: %\DTLifcurrency{\pounds5.99}{currency}{not currency}. %Note, however, that %\begin{verbatim} %\DTLifcurrency{US\$5.99}{currency}{not currency} %\end{verbatim} %produces: %\DTLifcurrency{US\$5.99}{currency}{not currency}. If you want %this to be considered currency, you will have to add the %sequence "US\$" to the set of currency symbols: %\begin{verbatim} %\DTLnewcurrencysymbol{US\$}% %\DTLifcurrency{US\$5.99}{currency}{not currency} %\end{verbatim} %this now produces: %\DTLnewcurrencysymbol{US\$}\relax %\DTLifcurrency{US\$5.99}{currency}{not currency}. % %This document has used the \sty{textcomp} package which defines %\cs{texteuro}, so this is also considered to be currency. For %example: %\begin{verbatim} %\DTLifcurrency{\texteuro5.99}{currency}{not currency} %\end{verbatim} %produces: %\DTLifcurrency{\texteuro5.99}{currency}{not currency}. % %The preferred method is to display the euro symbol in a sans-serif %font, but %\begin{verbatim} %\DTLifcurrency{\textsf{\texteuro}5.99}{currency}{not currency} %\end{verbatim} %will produce: %\DTLifcurrency{\textsf{\texteuro}5.99}{currency}{not currency}. % %It is better to define a new command, for example: %\begin{verbatim} %\DeclareRobustCommand*{\euro}{\textsf{\texteuro}} %\end{verbatim} %and add that command to the list of currency symbols. In fact, %in this case, if you define the command \cs{euro} in the %preamble, it will automatically be added to the list of known %currency symbols. If however you define \cs{euro} in the document, %you will have to add it using \ics{DTLnewcurrencysymbol}. For %example: %\begin{verbatim} %\newcommand*{\euro}{\textsf{\texteuro}}% %\DTLnewcurrencysymbol{\euro}% %\DTLifcurrency{\euro5.99}{currency}{not currency} %\end{verbatim} %produces: %\DeclareRobustCommand*{\euro}{\textsf{\texteuro}}\relax %\DTLnewcurrencysymbol{\euro}\relax %\DTLifcurrency{\euro5.99}{currency}{not currency}. % %\begin{definition}[\DescribeMacro{\DTLifcurrencyunit}]% %\cs{DTLifcurrencyunit}\marg{text}\marg{symbol}\marg{true part}\marg{false part} %\end{definition} %If \meta{text} is currency, and uses \meta{symbol} as the unit of %currency, then do \meta{true part} otherwise do \meta{false part}. %For example: %\begin{verbatim} %\DTLifcurrencyunit{\$6.99}{\$}{dollars}{not dollars} %\end{verbatim} %produces: %\DTLifcurrencyunit{\$6.99}{\$}{dollars}{not dollars}. %Another example: %\begin{verbatim} %\def\cost{\euro10.50}% %\DTLifcurrencyunit{\cost}{\euro}{euros}{not euros} %\end{verbatim} %produces: %\def\cost{\euro10.50}\relax %\DTLifcurrencyunit{\cost}{\euro}{euros}{not euros}. % %\begin{definition}[\DescribeMacro{\DTLifnumerical}]% %\cs{DTLifnumerical}\marg{text}\marg{true part}\marg{false part} %\end{definition} %If \meta{text} is numerical (either an integer, real number or %currency) then do \meta{true part} otherwise do %\meta{false part}. %For example: %\begin{verbatim} %\DTLifnumerical{1,000.0}{number}{string}. %\end{verbatim} %produces: \DTLifnumerical{1,000.0}{number}{string}. %Whereas %\begin{verbatim} %\DTLsetnumberchars{.}{,}% %\DTLifnumerical{1,000.0}{number}{string}. %\end{verbatim} %produces: %\DTLsetnumberchars{.}{,}\relax %\DTLifnumerical{1,000.0}{number}{string}. %Since the number group character is now a full stop, and the %decimal character is now a comma. (The number group character %may only appear before the decimal character, not after it.) % %Currency is also considered to be numerical: %\begin{verbatim} %\DTLsetnumberchars{,}{.}% %\DTLifnumerical{\$1,000.0}{number}{string}. %\end{verbatim} %produces: %\DTLsetnumberchars{,}{.}\relax %\DTLifnumerical{\$1,000.0}{number}{string}. % %\begin{definition}[\DescribeMacro{\DTLifstring}]% %\cs{DTLifstring}\marg{text}\marg{true part}\marg{false part} %\end{definition} %This is the opposite of \cs{DTLifnumerical}. If \meta{text} is %not numerical, do \meta{true part}, otherwise do \meta{false part}. % %\begin{definition}[\DescribeMacro{\DTLifcasedatatype}]% %\cs{DTLifcasedatatype}\marg{text}\marg{string case}\marg{int case}\marg{real case}\marg{currency case} %\end{definition} %If \meta{text} is a string do \meta{string case}, if \meta{text} %is an integer do \meta{int case}, if \meta{text} is a real number %do \meta{real case}, if \meta{text} is currency do %\meta{currency case}. For example: %\begin{verbatim} %\DTLifcasedatatype{1,000}{string}{integer}{real}{currency} %\end{verbatim} %produces: %\DTLifcasedatatype{1,000}{string}{integer}{real}{currency}. % %\begin{definition}[\DescribeMacro{\DTLifnumeq}]% %\cs{DTLifnumeq}\marg{num1}\marg{num2}\marg{true part}\marg{false part} %\end{definition} %If \meta{num1} is equal to \meta{num2}, then do \meta{true part}, %otherwise do \meta{false part}. Note that both \meta{num1} and %\meta{num2} must be numerical (either integers, real numbers or %currency). The currency symbol is ignored when determining %equality. For example %\begin{verbatim} %\DTLifnumeq{\pounds10.50}{10.5}{true}{false} %\end{verbatim} %produces: %\DTLifnumeq{\pounds10.50}{10.5}{true}{false}, since they are %considered to be numerically equivalent. Likewise: %\begin{verbatim} %\DTLifnumeq{\pounds10.50}{\$10.50}{true}{false} %\end{verbatim} %produces: %\DTLifnumeq{\pounds10.50}{\$10.50}{true}{false}. % %\begin{definition}[\DescribeMacro{\DTLifstringeq}]% %\cs{DTLifstringeq}\marg{string1}\marg{string2}\marg{true part}\marg{false part} %\end{definition} %\begin{definition}[\DescribeMacro{\DTLifstringeq*}]% %\cs{DTLifstringeq*}\marg{string1}\marg{string2}\marg{true part}\marg{false part} %\end{definition} %If \meta{string1} and \meta{string2} are the same, then do %\meta{true part}, otherwise do \meta{false part}. The starred %version ignores the case, the unstarred version is case %sensitive. Both %\meta{string1} and \meta{string2} are considered to be strings, %so for example: %\begin{verbatim} %\DTLifstringeq{10.50}{10.5}{true}{false} %\end{verbatim} %produces: %\DTLifstringeq{10.50}{10.5}{true}{false}. % %Note that %\begin{verbatim} %\DTLifstringeq{Text}{text}{true}{false} %\end{verbatim} %produces: %\DTLifstringeq{Text}{text}{true}{false}, whereas %\begin{verbatim} %\DTLifstringeq*{Text}{text}{true}{false} %\end{verbatim} %produces: %\DTLifstringeq*{Text}{text}{true}{false}, however it should also be %noted that many commands will be ignored, so: %\begin{verbatim} %\DTLifstringeq{\uppercase{t}ext}{text}{true}{false} %\end{verbatim} %produces: %\DTLifstringeq{\uppercase{t}ext}{text}{true}{false}. % %Spaces are considered to be equivalent to \cs{space} and "~". For %example: %\begin{verbatim} %\DTLifstringeq{an apple}{an~apple}{true}{false} %\end{verbatim} %produces: %\DTLifstringeq{an apple}{an~apple}{true}{false}. Consecutive spaces %are treated as the same, for example: %\begin{verbatim} %\DTLifstringeq{an apple}{an apple}{true}{false} %\end{verbatim} %produces: %\DTLifstringeq{an apple}{an apple}{true}{false}. % %\begin{definition}[\DescribeMacro{\DTLifeq}]% %\cs{DTLifeq}\marg{arg1}\marg{arg2}\marg{true part}\marg{false part} %\end{definition} %\begin{definition}[\DescribeMacro{\DTLifeq*}]% %\cs{DTLifeq*}\marg{arg1}\marg{arg2}\marg{true part}\marg{false part} %\end{definition} %If both \meta{arg1} and \meta{arg2} are numerical, then this is %equivalent to \cs{DTLifnumeq}, otherwise it is equivalent to %\cs{DTLifstringeq} (when using \cs{DTLifeq}) or \cs{DTLifstringeq*} %(when using \cs{DTLifeq*}). % %\begin{definition}[\DescribeMacro{\DTLifnumlt}]% %\cs{DTLifnumlt}\marg{num1}\marg{num2}\marg{true part}\marg{false part} %\end{definition} %If \meta{num1} is less than \meta{num2}, then do \meta{true part}, %otherwise do \meta{false part}.

The optional argument \meta{options} %is a key=value list of options. Available options are: %\begin{description} %\item[\cmdopt{DTLloaddb}{noheader}] This is a boolean value and %indicates if the file does not contain a header. If no value is %supplied, "true" is assumed (i.e.\ the file doesn't contain a header %row). If this option is omitted, it is assumed that the file %contains a header row. % %\item[\cmdopt{DTLloaddb}{keys}] This is a comma-separated list of %keys to use, where the keys are listed in the same order as the %columns. If the file has a header, these keys will override the %values given in the header row. If the file has no header row and no %keys are supplied in \meta{options}, then the keys will be given by %\cs{dtldefaultkey}\meta{n}, where \meta{n} is the column number and %\DescribeMacro{\dtldefaultkey}\cs{dtldefaultkey} defaults to %``\dtldefaultkey''. Note that the list of keys must be delimited by %braces since they contain commas. For example: %\begin{verbatim} %\DTLloaddb[noheader,keys={Temperature,Time,T2G}]{data}{data.csv} %\end{verbatim} % %\item[\cmdopt{DTLloaddb}{headers}] This is a comma-separated list of %headers.

The label can't simply be constructed from the %surname, as there are two students with the same surname. In order %to create a unique label, I can either construct a label from %both the surname and the first name, or I can use the student's %registration number, or I can use the student's score, since all %the scores are unique. The former method will cause a problem since %one of the names (Z\"oe) contains an accent command. Although %the registration numbers are all unique, they are not particularly %memorable, so I shall instead use the scores. %\begin{verbatim} %\begin{table}[htbp] %\caption{Student scores} %\centering %\begin{tabular}{cllc} %\bfseries Row & %\bfseries First Name & %\bfseries Surname & %\bfseries Score (\%)% %\DTLforeach*{scores}{% %\firstname=FirstName,\surname=Surname,\score=Score}{% %\label{row:\score}\\\theDTLrowi & %\firstname & \surname & \score}% %\end{tabular} %\end{table} % %Jane Brown scored the highest (75\%), her score can be seen on %row~\ref{row:75}. %\end{verbatim} %This produces \autoref{tab:scoreslab} and the following text: %Jane Brown scored the highest (75\%), her score can be seen on %row~\ref*{row:75}. % %Notes: %\begin{itemize} %\item the \cs{label} command is placed before %"\\" to ensure that it is in the same scope as the command %"\refstepcounter{DTLrowi}". % %\item To avoid unwanted spaces the end of line characters are %commented out with the percent (\texttt{\%}) symbol. %\end{itemize} % %\begin{table}[htbp] %\caption[Student scores (labelling rows)]{Student %scores}\label{tab:scoreslab} %\centering %\begin{tabular}{cllc} %\bfseries Row & %\bfseries First Name & %\bfseries Surname & %\bfseries Score (\%)\relax %\DTLforeach*{scores}{\firstname=FirstName,\surname=Surname,\score=Score}{\relax %\label{row:\score}\\\theDTLrowi & %\firstname & \surname & \score}\relax %\end{tabular} %\end{table} %\end{example} % %\begin{example}{Filtering Rows}{ex:filter} %As mentioned earlier, the optional argument \meta{condition} of %\ics{DTLforeach} provides a means to exclude certain rows. %This example uses the database defined in \autoref{ex:scores}, %but only displays the information for students whose marks are %above 60.

The \meta{settings} argument is a comma separated %list of \meta{setting}"="\meta{value} pairs. There are two settings %that must be specified \setting{DTLplot}{x} and \setting{DTLplot}{y}. %The other settings are optional. Note that any value that contains %a comma, must be enclosed in braces.

Note where any setting requires %a number, or list of numbers (such as \setting{DTLplot}{bounds}) %the number must be supplied in standard decimal notation (i.e.\ %no currency, no number groups, and a full stop as the decimal %point). Available settings are as follows: %\begin{description} %\item[\setting{DTLplot}{x}] The database key %that specifies the $x$ co-ordinates. This setting is required. % %\item[\setting{DTLplot}{y}] The database key that specifies %the $y$ co-ordinates.

You may use \cs{relax} as an element %of the list to suppress markers for the corresponding plot. %For example: "marks={\pgfuseplotmark{o},\relax}" will use an %open circle marker for the first database, and no markers for the %second database listed in \meta{db list}. % %\item[\setting{DTLplot}{lines}] A comma separated list of %line style settings. (This should typically be a list of %\cs{pgfsetdash} commands, see the \sty{pgf} manual for %further details on how to set the line style.) An empty value %will use the current line style. %You may use \cs{relax} as an element %of the list to suppress line for the corresponding plot. %For example: "lines={\relax,\pgfsetdash{}{0pt}}" %will have no lines for the first database, and a solid line %for the second database listed in \meta{db list}. % %\item[\setting{DTLplot}{width}] The width of the plot.

In this section the $x$ axis refers to the horizontal %axis when plotting a vertical bar chart and to the vertical axis %when plotting a horizontal bar chart. The $x$ axis units are in %increments of one bar. The $y$ axis refers to the vertical axis %when plotting a vertical bar chart and to the horizontal axis when %plotting a horizontal bar chart. The $y$ axis uses the same %co-ordinates as the data. The bars may have an upper and lower %label. In a vertical bar chart, the lower label is placed below %the $x$ axis and the upper label is placed above the top of the bar. %In a horizontal bar chart, the lower label is placed to the left of %the $x$ axis and the upper label is placed to the right of the %end of the bar. (This is actually a misnomer as it is possible %for the ``upper'' label to be below the ``lower'' label if a %bar has a negative value, however the bars are considered to %be anchored on the $x$ axis, and the other end of the bar is %considered to be the ``upper'' end, regardless of its %direction.) % %The \sty{databar} package options are as follows: %\begin{description} %\item[{\pkgopt[databar]{color}}] Created coloured bar charts %(default). % %\item[{\pkgopt[databar]{gray}}] Created grey scale bar charts. % %\item[{\pkgopt[databar]{vertical}}] Created vertical bar charts %(default). % %\item[{\pkgopt[databar]{horizontal}}] Created horizontal bar charts. %\end{description} % % % %\begin{definition}[\DescribeMacro{\DTLbarchart}]% %\cs{DTLbarchart}\oarg{condition}\marg{db name}\marg{settings}\marg{values} %\end{definition} %\begin{definition}[\DescribeMacro{\DTLmultibarchart}]% %\cs{DTLmultibarchart}\oarg{condition}\marg{db name}\marg{settings}\marg{values} %\end{definition} %These commands both create a bar chart from the information in %the database \meta{db name}, where \meta{condition} is the same %as the optional argument for \ics{DTLforeach} described in %\autoref{sec:dbforeach}, and \meta{values} is the same as the %penultimate argument of \ics{DTLforeach}.

The database can then be %sorted using \cs{DTLsort}, described in \autoref{sec:sort}. %For example, you may want to sort the bibliography in %reverse chronological order. Once you have sorted the bibliography, %you can display it using \cs{DTLbibliography}, described in %\autoref{sec:thebib}, or you can iterate through the database %using \cs{DTLforeachbib}, described in \autoref{sec:foreachbib}. % %Note that the \sty{databib} %package is not automatically loaded by \sty{datatool}, so if %you want to use it, you must load it using %"\usepackage{databib}". % %\importantpar The purpose of this package is to provide a means for %authors to format their own bibliography style where there is no %bibliography style file available that produces the desired results. %The \cs{DTLsort} macro uses a much less efficient sorting algorithm %than \BibTeX, and loading the bibliography as a \sty{datatool} %database is much slower than loading a standard \ext{bbl} file. If %you have a large database, and you are worried that \LaTeX\ may have %become stuck, try using the \pkgopt{verbose} option to \sty{datatool} %or use the command \cs{dtlverbosetrue}. This will print informative %messages to the console and transcript file, to let you know what's %going on. % %\subsection{\texorpdfstring{\BibTeX}{BibTeX}: An Overview} %\label{sec:bibtex} %This document assumes that you have at least some passing %familiarity with \BibTeX, but here follows a brief refresher. % %\BibTeX\ is an external application used in conjunction with \LaTeX. %When you run \BibTeX, you need to specify the name of the document's %auxiliary file (without the \ext{aux} extension). \BibTeX\ then reads %this file and looks for the commands \cs{bibstyle} (which indicates %which bibliography style (\ext{bst}) file to load), \cs{bibdata} %(which indicates which bibliography database (\ext{bib}) files to %load) and \cs{citation} (produced by \cs{cite} and \cs{nocite}, which %indicates which entries should be included in the bibliography). %\BibTeX\ then creates a file with the extension \ext{bbl} which %contains the bibliography, formatted according to the layout defined %in the bibliography style file. % %In general, given a document called, say, \texttt{mydoc.tex}, you %will have to perform the following steps to ensure that the %bibliography and all citations are up-to-date: %\begin{enumerate} %\item %\begin{verbatim} %latex mydoc %\end{verbatim} %This writes the citation information to the auxiliary file. %The bibliography currently doesn't exists, so it isn't displayed. %Citations will appear in the document as ?? since the internal %cross-references don't exist yet. % %\item %\begin{verbatim} %bibtex mydoc %\end{verbatim} %This reads the auxiliary file, and creates a file with the extension %\ext{bbl} which typically contains the typeset bibliography. % %\item %\begin{verbatim} %latex mydoc %\end{verbatim} %Now that the \ext{bbl} file exists, the bibliography can be input %into the document. The internal cross-referencing information for the %bibliography can now be written to the auxiliary file. % %\item %\begin{verbatim} %latex mydoc %\end{verbatim} %The cross-referencing information can be read from the auxiliary %file. %\end{enumerate} % %\subsubsection{\texorpdfstring{\BibTeX}{BibTeX} database} % %The bibliographic data required by \BibTeX\ must be stored in %a file with the extension \ext{bib}, where each entry is stored %in the form:\par\vskip\baselineskip\noindent %{\obeylines %\noindent\texttt{@}\meta{entry\_type}\verb|{|\meta{cite\_key}\texttt, % \meta{field\_name} \texttt{=} \char`\"\meta{value}\char`\"\texttt, % \mbox{}\vdots % \meta{field\_name} \texttt{=} \char`\"\meta{value}\char`\" %\noindent\verb|}| %} %\par\vskip\baselineskip\noindent %Note that curly braces "{" and "}" may be used instead of \verb|"| %and \verb|"|. % %The entry type, given by \meta{entry\_type} above, indicates %the type of document. This may be one of: "article", "book", %"booklet", "inbook", "incollection", "inproceedings"\footnote %{Note that \texttt{conference} is a synonym for \texttt{inproceedings}.}, %"manual", %"mastersthesis", "misc", "phdthesis", "proceedings", \linebreak %"techreport" or "unpublished". % %The \meta{cite\_key} above is a unique label identifying this %entry, and is the label used in the argument of \cs{cite} or %\cs{nocite}. The available fields depends on the entry type, for %example, the field "journal" is required for the "article" entry %type, but is ignored for the "inproceedings" entry type. The standard %fields are: "address", "author", "booktitle", "chapter", "edition", %"editor", "howpublished", "institution", "journal", "key", "month", %"note", "number", "organization", "pages", "publisher", "school", %"series", "title", "type", "volume" and "year". % %Author and editor names must be entered in one of the following %ways: %\begin{enumerate} %\item \meta{First names} \meta{von part} \meta{Surname}, \meta{Jr part} % %The \meta{von part} is optional and is identified by the name(s) %starting with lowercase letters. The final comma followed by %\meta{Jr part} is also optional. Examples: %\begin{verbatim} %author = "Henry James de Vere" %\end{verbatim} %In the above, the first names are Henry James, the ``von part'' is %de and the surname is Vere. There is no ``junior part''. %\begin{verbatim} %author = "Mary-Jane Brown, Jr" %\end{verbatim} %In the above, the first name is Mary-Jane, there is no von part, %the surname is Brown and the junior part is Jr. %\begin{verbatim} %author = "Peter {Murphy Allen}" %\end{verbatim} %In the above, the first name is Peter, and the surname is Murphy %Allen. Note that in this case, the surname must be grouped, otherwise %Murphy would be considered part of the forename. %\begin{verbatim} %author = "Maria Eliza {\uppercase{d}e La} Cruz" %\end{verbatim} %In the above, the first name is Maria Eliza, the von part is %De La, and the surname is Cruz. In this case, the von part starts %with an uppercase letter, but specifying %\begin{verbatim} %author = "Maria Eliza De La Cruz" %\end{verbatim} %would make \BibTeX\ incorrectly classify ``Maria Eliza De La'' as %the first names, and the von part would be empty. Since \BibTeX\ %doesn't understand \LaTeX\ commands, using "{\uppercase{d}e La}" %will trick \BibTeX\ into thinking that it starts with a lower %case letter. % %\item \meta{von part} \meta{Surname}, \meta{Forenames} % %Again the \meta{von part} is optional, and is determined by the %case of the first letter. For example: %\begin{verbatim} %author = "de Vere, Henry James" %\end{verbatim} %\end{enumerate} % %Multiple authors or editors should be separated by the key word %"and", for example: %\begin{verbatim} %author = "Michel Goossens and Frank Mittlebach and Alexander Samarin" %\end{verbatim} % %Below is an example of a book entry: %\begin{verbatim} %@book{latexcomp, % title = "The \LaTeX\ Companion", % author = "Michel Goossens and Frank Mittlebach and % Alexander Samarin", % publisher = "Addison-Wesley", % year = 1994 %} %\end{verbatim} %Note that numbers may be entered without delimiters, as in "year = 1994". %There are also some predefined strings, including those for the month %names. You should always use these strings instead of the actual %month name, as the way the month name is displayed depends on the %bibliography style. For example: %\begin{verbatim} %@article{Cawley2007b, %author = "Gavin C. Cawley and Nicola L. C. Talbot", %title = "Preventing over-fitting in model selection via {B}ayesian % regularisation of the hyper-parameters", %journal = "Journal of Machine Learning Research", %volume = 8, %pages = "841--861", %month = APR, %year = 2007 %} %\end{verbatim} % %You can concatenate strings using the "#" character, for example: %\begin{verbatim} %month = JUL # "~31~--~" # AUG # "~4", %\end{verbatim} %Depending on the bibliography style, this may be displayed as: %July~31~--~August~4, or it may be displayed as: %Jul~31~--~Aug~4.

If the \ext{bbl} file doesn't exist, the %database \meta{db name} will remain empty. %\end{enumerate} % %You then need to run your document through \LaTeX\ (or PDF\LaTeX) %and then run \BibTeX\ on the auxiliary file, as described in %\autoref{sec:bibtex}.

The next %time you \LaTeX\ your document, this file will be read, and the %information will be added to \meta{db name}. % %\importantpar Note that %\cs{DTLloadbbl} doesn't generate any text. Once you have loaded %the data, you can display the bibliography uses %\cs{DTLbibliography} (described below) or you can iterate %through it using \cs{DTLforeachbibentry} described in %\autoref{sec:foreachbib}. % %Note that the \texttt{databib.bst} \BibTeX\ style file provides %the following additional fields: "isbn", "doi", "pubmed", "url" %and "abstract". %However these fields are ignored by the three predefined %\sty{databib} styles ("plain", "abbrv" and "alpha").

I have a file called "nlct.bib" which contains %all my publications which I keep in the directory %\verb!$HOME/texmf/bibtex/bib/!.

This tells \BibTeX\ to use "databib.bst" %(which is supplied with this package). You therefore shouldn't %use \cs{bibliographystyle}. % %\item writes the line %\begin{verbatim} %\bibdata{nlct} %\end{verbatim} %to the auxiliary file. This tells \BibTeX\ that the bibliography %data is stored in the file "nlct.bib". Since I have placed this %file in \TeX's search path, \BibTeX\ will be able to find it. % %\item creates a \sty{datatool} database called "mybib". % %\item if the \ext{bbl} file ("mypubs.bbl" in this example) exists, %it loads this file (which adds the bibliography data to the %database), otherwise it does nothing further. % %\end{enumerate} % %\item In my \BibTeX\ database ("nlct.bib" in this example), I %have remembered to use the \BibTeX\ month macros: "jan", "feb" %etc. This means that the months are stored in the database in %the form \cs{DTLmonthname}\marg{nn}, where \meta{nn} is a two %digit number from 01 to 12. \cs{DTLsort} ignores command names %when it compares strings, which means I can not only sort by %year, but also by month\footnote{as long as I haven't put anything %before the month name in the bibliography file, e.g.\ %\mbox{\texttt{month = "2~" \# apr}} will sort by 2~03, instead of %03}. % %\item Once I have loaded and sorted my database, I can then %display it using \cs{DTLbibliography}. This uses the style %given by the \sty{databib} \pkgopt[databib]{style} package option, %or the \cs{DTLbibliographystyle} command, both of which are %described in \autoref{sec:bibstyle}. % %\item I have filtered the bibliography using the optional %argument\linebreak "[\DTLbibfieldisge{Year}{2000}]", which checks if the %year field of the current entry is greater than or equal to %2000. (Note that if an entry has no year field, the condition %evaluates to false, and the entry will be omitted from the %bibliography.) % %\item If the bibliography database is large, sorting and creating %the bibliography may take a while.

Columns % also have an associated data type which may be: 0 (column % contains strings), 1 (column contains integers), 2 (column % contains real numbers), 3 (column contains currency) or % \meta{empty} (column contains no data). Since the key sometimes % has to be expanded, a header is also available in the event % that the user wants to use \cs{DTLdisplaydb} or % \cs{DTLdisplaylongdb} and requires a column header that would % cause problems if used as a key. The general column % information is stored in a token register where each column % has information stored in the form:\par %\verb|\db@plist@elt@w|% %\verb|\db@col@id@w| \meta{index}\verb|\db@col@id@end@|% %\verb|\db@key@id@w| \meta{key}\verb|\db@key@id@end@|% %\verb|\db@type@id@w| \meta{type}\verb|\db@type@id@end@|% %\verb|\db@header@id@w| \meta{type}\verb|\db@header@id@end@|% %\verb|\db@col@id@w| \meta{index}\verb|\db@col@id@end@|% %\verb|\db@plist@elt@end@| % % The column name (\meta{key}) is mapped to the column index % using \cs{dtl@ci@}\meta{db}"@"\meta{key} where \meta{db} is % the database name. % %\begin{macro}{\DTLnewdb} %\changes{2.0}{2009 February 27}{Changed way database is stored} % \cs{DTLnewdb}\marg{name} % initialises a database called \meta{name}. % \begin{macrocode} \newcommand*{\DTLnewdb}[1]{% % \end{macrocode} % Check if there is already a database with this name. % \begin{macrocode} \DTLifdbexists{#1}% {% \PackageError{datatool}{Database `#1' already exists}{}% }% {% % \end{macrocode} % Define new database.
