+# pdftexcmds
+
+Version: 2020-06-27 v0.33
+
+pdftexcmds package for LaTeX
+
+LuaTeX provides most of the commands of pdfTeX 1.40. However
+a number of utility functions are removed. This package tries to fill
+the gap and implements some of the missing primitive using Lua.
+Also provides similar wrappers for XeLaTeX and other engines that provide
+these primitives, under possibly different names.

+% a number of utility functions are removed. This package tries to fill

+% \section{Documentation}
+%
+% Some primitives of \hologo{pdfTeX} \cite{pdftex-manual}
+% are not defined by \hologo{LuaTeX} \cite{luatex-manual}.
+% This package implements macro based solutions using Lua code
+% for the following missing \hologo{pdfTeX} primitives;
+% \begin{compactitem}
+% \item \cs{pdfstrcmp}
+% \item \cs{pdfunescapehex}
+% \item \cs{pdfescapehex}
+% \item \cs{pdfescapename}
+% \item \cs{pdfescapestring}
+% \item \cs{pdffilesize}
+% \item \cs{pdffilemoddate}
+% \item \cs{pdffiledump}
+% \item \cs{pdfmdfivesum}
+% \item \cs{pdfresettimer}
+% \item \cs{pdfelapsedtime}
+% \item |\immediate\write18|
+% \end{compactitem}
+% The original names of the primitives cannot be used:
+% \begin{itemize}
+% \item
+% The syntax for their arguments cannot easily
+% simulated by macros. The primitives using key words
+% such as |file| (\cs{pdfmdfivesum}) or |offset| and |length|
+% (\cs{pdffiledump}) and uses \meta{general text} for the other
+% arguments. Using token registers assignments, \meta{general text} could
+% be catched. However, the simulated primitives are expandable
+% and register assignments would destroy this important property.
+% (\meta{general text} allows something like |\expandafter\bgroup ...}|.)
+% \item
+% The original primitives can be expanded using one expansion step.
+% The new macros need two expansion steps because of the additional
+% macro expansion. Example:
+% \begin{quote}
+% |\expandafter\foo\pdffilemoddate{file}|\\
+% vs.\\
+% |\expandafter\expandafter\expandafter|\\
+% |\foo\pdf at filemoddate{file}|
+% \end{quote}
+% \end{itemize}
+%
+% \hologo{LuaTeX} isn't stable yet and thus the status of this package is
+% \emph{experimental}. Feedback is welcome.
+%
+% \subsection{General principles}
+%
+% \begin{description}
+% \item[Naming convention:]
+% Usually this package defines a macro |\pdf@|\meta{cmd} if
+% \hologo{pdfTeX} provides |\pdf|\meta{cmd}.
+% \item[Arguments:] The order of arguments in |\pdf@|\meta{cmd}
+% is the same as for the corresponding primitive of \hologo{pdfTeX}.
+% The arguments are ordinary undelimited \hologo{TeX} arguments,
+% no \meta{general text} and without additional keywords.
+% \item[Expandibility:]
+% The macro |\pdf@|\meta{cmd} is expandable if the
+% corresponding \hologo{pdfTeX} primitive has this property.
+% Exact two expansion steps are necessary (first is the macro
+% expansion) except for \cs{pdf at primitive} and \cs{pdf at ifprimitive}.
+% The latter ones are not macros, but have the direct meaning of the
+% primitive.
+% \item[Without \hologo{LuaTeX}:]
+% The macros |\pdf@|\meta{cmd} are mapped to the commands
+% of \hologo{pdfTeX} if they are available. Otherwise they are undefined.
+% \item[Availability:]
+% The macros that the packages provides are undefined, if
+% the necessary primitives are not found and cannot be
+% implemented by Lua.
+% \end{description}
+%
+% \subsection{Macros}
+%
+% \subsubsection[Strings]{Strings \cite[``7.15 Strings'']{pdftex-manual}}
+%
+% \begin{declcs}{pdf at strcmp} \M{stringA} \M{stringB}
+% \end{declcs}
+% Same as |\pdfstrcmp{|\meta{stringA}|}{|\meta{stringB}|}|.
+%
+% \begin{declcs}{pdf at unescapehex} \M{string}
+% \end{declcs}
+% Same as |\pdfunescapehex{|\meta{string}|}|.
+% The argument is a byte string given in hexadecimal notation.
+% The result are character tokens from 0 until 255 with
+% catcode 12 and the space with catcode 10.
+%
+% \begin{declcs}{pdf at escapehex} \M{string}\\
+% \cs{pdf at escapestring} \M{string}\\
+% \cs{pdf at escapename} \M{string}
+% \end{declcs}
+% Same as the primitives of \hologo{pdfTeX}. However \hologo{pdfTeX} does not
+% know about characters with codes 256 and larger. Thus the
+% string is treated as byte string, characters with more than
+% eight bits are ignored.
+%
+% \subsubsection[Files]{Files \cite[``7.18 Files'']{pdftex-manual}}
+%
+% \begin{declcs}{pdf at filesize} \M{filename}
+% \end{declcs}
+% Same as |\pdffilesize{|\meta{filename}|}|.
+%
+% \begin{declcs}{pdf at filemoddate} \M{filename}
+% \end{declcs}
+% Same as |\pdffilemoddate{|\meta{filename}|}|.
+%
+% \begin{declcs}{pdf at filedump} \M{offset} \M{length} \M{filename}
+% \end{declcs}
+% Same as |\pdffiledump offset| \meta{offset} |length| \meta{length}
+% |{|\meta{filename}|}|. Both \meta{offset} and \meta{length} must
+% not be empty, but must be a valid \hologo{TeX} number.
+%
+% \begin{declcs}{pdf at mdfivesum} \M{string}
+% \end{declcs}
+% Same as |\pdfmdfivesum{|\meta{string}|}|. Keyword |file| is supported
+% by macro \cs{pdf at filemdfivesum}.
+%
+% \begin{declcs}{pdf at filemdfivesum} \M{filename}
+% \end{declcs}
+% Same as |\pdfmdfivesum file{|\meta{filename}|}|.
+%
+% \subsubsection[Timekeeping]{Timekeeping \cite[``7.17 Timekeeping'']{pdftex-manual}}
+%
+% The timekeeping macros are based on Andy Thomas' work \cite{AndyThomas:Analog}.
+%
+% \begin{declcs}{pdf at resettimer}
+% \end{declcs}
+% Same as \cs{pdfresettimer}, it resets the internal timer.
+%
+% \begin{declcs}{pdf at elapsedtime}
+% \end{declcs}
+% Same as \cs{pdfelapsedtime}. It behaves like a read-only integer.
+% For printing purposes it can be prefixed by \cs{the} or \cs{number}.
+% It measures the time in scaled seconds (seconds multiplied with 65536)
+% since the latest call of \cs{pdf at resettimer} or start of
+% program/package. The resolution, the shortest time interval that
+% can be measured, depends on the program and system.
+% \begin{itemize}
+% \item \hologo{pdfTeX} with |gettimeofday|: $\ge$ 1/65536\,s
+% \item \hologo{pdfTeX} with |ftime|: $\ge$ 1\,ms
+% \item \hologo{pdfTeX} with |time|: $\ge$ 1\,s
+% \item \hologo{LuaTeX}: $\ge$ 10\,ms\\
+% (|os.clock()| returns a float number with two decimal digits in
+% \hologo{LuaTeX} beta-0.70.1-2011061416 (rev 4277)).
+% \end{itemize}
+%
+% \subsubsection[Miscellaneous]{Miscellaneous \cite[``7.21 Miscellaneous'']{pdftex-manual}}
+%
+% \begin{declcs}{pdf at draftmode}
+% \end{declcs}
+% If the \TeX\ compiler knows \cs{pdfdraftmode} or \cs{draftmode}
+% (\hologo{pdfTeX},
+% \hologo{LuaTeX}), then \cs{pdf at draftmode} returns, whether
+% this mode is enabled. The result is an implicit number:
+% one means the draft mode is available and enabled.
+% If the value is zero, then the mode is not active or
+% \cs{pdfdraftmode} is not available.
+% An explicit number is yielded by \cs{number}\cs{pdf at draftmode}.
+% The macro cannot
+% be used to change the mode, see \cs{pdf at setdraftmode}.
+%
+% \begin{declcs}{pdf at ifdraftmode} \M{true} \M{false}
+% \end{declcs}
+% If \cs{pdfdraftmode} is available and enabled, \meta{true} is
+% called, otherwise \meta{false} is executed.
+%
+% \begin{declcs}{pdf at setdraftmode} \M{value}
+% \end{declcs}
+% Macro \cs{pdf at setdraftmode} expects the number zero or one as
+% \meta{value}. Zero deactivates the mode and one enables the draft mode.
+% The macro does not have an effect, if the feature \cs{pdfdraftmode} is not
+% available.
+%
+% \begin{declcs}{pdf at shellescape}
+% \end{declcs}
+% Same as |\pdfshellescape|. It is or expands to |1| if external
+% commands can be executed and |0| otherwise. In \hologo{pdfTeX} external
+% commands must be enabled first by command line option or
+% configuration option. In \hologo{LuaTeX} option |--safer| disables
+% the execution of external commands.
+%
+% In \hologo{LuaTeX} before 0.68.0 \cs{pdf at shellescape} is not
+% available due to a bug in |os.execute()|. The argumentless form
+% crashes in some circumstances with segmentation fault.
+% (It is fixed in version 0.68.0 or revision 4167 of \hologo{LuaTeX}.
+% and packported to some version of 0.67.0).
+%
+% Hints for usage:
+% \begin{itemize}
+% \item Before its use \cs{pdf at shellescape} should be tested,
+% whether it is available. Example with package \xpackage{ltxcmds}
+% (loaded by package \xpackage{pdftexcmds}):
+%\begin{quote}
+%\begin{verbatim}
+%\ltx at IfUndefined{pdf at shellescape}{%
+% % \pdf at shellescape is undefined
+%}{%
+% % \pdf at shellescape is available
+%}
+%\end{verbatim}
+%\end{quote}
+% Use \cs{ltx at ifundefined} in expandable contexts.
+% \item \cs{pdf at shellescape} might be a numerical constant,
+% expands to the primitive, or expands to a plain number.
+% Therefore use it in contexts where these differences does not matter.
+% \item Use in comparisons, e.g.:
+% \begin{quote}
+% |\ifnum\pdf at shellescape=0 ...|
+% \end{quote}
+% \item Print the number: |\number\pdf at shellescape|
+% \end{itemize}
+%
+% \begin{declcs}{pdf at system} \M{cmdline}
+% \end{declcs}
+% It is a wrapper for |\immediate\write18| in \hologo{pdfTeX} or
+% |os.execute| in \hologo{LuaTeX}.
+%
+% In theory |os.execute|
+% returns a status number. But its meaning is quite
+% undefined. Are there some reliable properties?
+% Does it make sense to provide an user interface to
+% this status exit code?
+%
+% \begin{declcs}{pdf at primitive} \csi{cmd}
+% \end{declcs}
+% Same as \cs{pdfprimitive} in \hologo{pdfTeX} or \hologo{LuaTeX}.
+% In \hologo{XeTeX} the
+% primitive is called \cs{primitive}. Despite the current definition
+% of the command \csi{cmd}, it's meaning as primitive is used.
+%
+% \begin{declcs}{pdf at ifprimitive} \csi{cmd}
+% \end{declcs}
+% Same as \cs{ifpdfprimitive} in \hologo{pdfTeX} or
+% \hologo{LuaTeX}. \hologo{XeTeX} calls
+% it \cs{ifprimitive}. It is a switch that checks if the command
+% \csi{cmd} has it's primitive meaning.
+%
+% \subsubsection{Additional macro: \cs{pdf at isprimitive}}
+%
+% \begin{declcs}{pdf at isprimitive} \csi{cmd1} \csi{cmd2} \M{true} \M{false}
+% \end{declcs}
+% If \csi{cmd1} has the primitive meaning given by the primitive name
+% of \csi{cmd2}, then the argument \meta{true} is executed, otherwise
+% \meta{false}. The macro \cs{pdf at isprimitive} is expandable.
+% Internally it checks the result of \cs{meaning} and is therefore
+% available for all \hologo{TeX} variants, even the original \hologo{TeX}.
+% Example with \hologo{LaTeX}:
+%\begin{quote}
+%\begin{verbatim}
+%\makeatletter
+%\pdf at isprimitive{@@input}{input}{%
+% \typeout{\string\@@input\space is original\string\input}%
+%}{%
+% \typeout{Oops, \string\@@input\space is not the %
+% original\string\input}%
+%}
+%\end{verbatim}
+%\end{quote}
+%
+% \subsubsection{Experimental}
+%
+% \begin{declcs}{pdf at unescapehexnative} \M{string}\\
+% \cs{pdf at escapehexnative} \M{string}\\
+% \cs{pdf at escapenamenative} \M{string}\\
+% \cs{pdf at mdfivesumnative} \M{string}
+% \end{declcs}
+% The variants without |native| in the macro name are supposed to
+% be compatible with \hologo{pdfTeX}. However characters with more than
+% eight bits are not supported and are ignored. If \hologo{LuaTeX} is
+% running, then its UTF-8 coded strings are used. Thus the full
+% unicode character range is supported. However the result
+% differs from \hologo{pdfTeX} for characters with eight or more bits.
+%
+% \begin{declcs}{pdf at pipe} \M{cmdline}
+% \end{declcs}
+% It calls \meta{cmdline} and returns the output of the external
+% program in the usual manner as byte string (catcode 12, space with
+% catcode 10). The Lua documentation says, that the used |io.popen|
+% may not be available on all platforms. Then macro \cs{pdf at pipe}
+% is undefined.

+% \subsection{\cs{pdf at primitive}, \cs{pdf at ifprimitive}}
+%
+% Since version 1.40.0 \hologo{pdfTeX} has \cs{pdfprimitive} and
+% \cs{ifpdfprimitive}. And \cs{pdfprimitive} was fixed in
+% version 1.40.4.
+%
+% \hologo{XeTeX} provides them under the name \cs{primitive} and
+% \cs{ifprimitive}. \hologo{LuaTeX} knows both name variants,
+% but they have possibly to be enabled first (|tex.enableprimitives|).
+%
+% Depending on the format TeX Live uses a prefix |luatex|.

+% \section{Installation}
+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\CTANpkg{pdftexcmds}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/pdftexcmds/pdftexcmds.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/pdftexcmds/pdftexcmds.pdf}] Documentation.
+% \end{description}
+%
+% \subsection{Package installation}
+%
+% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
+% \docstrip\ archive. The files are extracted by running the
+% \xfile{.dtx} through \plainTeX:
+% \begin{quote}
+% \verb|tex pdftexcmds.dtx|
+% \end{quote}
+%
+% \paragraph{TDS.} Now the different files must be moved into
+% the different directories in your installation TDS tree
+% (also known as \xfile{texmf} tree):

+% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
+% TDS installing feature, then some files can already be in the right
+% place, see the documentation of \docstrip.
+%
+% \subsection{Refresh file name databases}
+%
+% If your \TeX~distribution
+% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
+% these. For example, \TeX\,Live\ users run \verb|texhash| or
+% \verb|mktexlsr|.
+%
+% \subsection{Some details for the interested}
+%
+% \paragraph{Unpacking with \LaTeX.}
+% The \xfile{.dtx} chooses its action depending on the format:
+% \begin{description}
+% \item[\plainTeX:] Run \docstrip\ and extract the files.
+% \item[\LaTeX:] Generate the documentation.
+% \end{description}
+% If you insist on using \LaTeX\ for \docstrip\ (really,
+% \docstrip\ does not need \LaTeX), then inform the autodetect routine
+% about your intention:
+% \begin{quote}
+% \verb|latex \let\install=y\input{pdftexcmds.dtx}|
+% \end{quote}
+% Do not forget to quote the argument according to the demands
+% of your shell.
+%
+% \paragraph{Generating the documentation.}
+% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
+% the documentation. The process can be configured by the
+% configuration file \xfile{ltxdoc.cfg}. For instance, put this
+% line into this file, if you want to have A4 as paper format:
+% \begin{quote}
+% \verb|\PassOptionsToClass{a4paper}{article}|
+% \end{quote}
+% An example follows how to generate the
+% documentation with pdf\LaTeX:
+% \begin{quote}
+%\begin{verbatim}
+%pdflatex pdftexcmds.dtx
+%bibtex pdftexcmds.aux
+%makeindex -s gind.ist pdftexcmds.idx
+%pdflatex pdftexcmds.dtx
+%makeindex -s gind.ist pdftexcmds.idx
+%pdflatex pdftexcmds.dtx
+%\end{verbatim}
