Also it always checks for -% the meaning of \cs{relax} and considers this as undefined. -% This macro is not expandable without \eTeX. -% -% \begin{declcs}{ltx@LocalExpandAfter} -% \end{declcs} -% It expands the token after the next token but in a local -% context. That is the difference to \cs{expandafter}. -% The local context discards the side effect of \cs{csname} -% and let the command undefined after the expansion step. -% -% \subsection{Stripping} -% -% \begin{declcs}{ltx@RemovePrefix}\\ -% \cs{ltx@StripPrefix} -% \end{declcs} -% All tokens up to and including the next available character -% `\textgreater' are thrown away.

The macro is expanded once and -% the contents is converted to characters with catcode 12 (other) -% and space tokens with catcode 10 (space). Then then sanitized -% contents is stored into the macro again. Since version 1.12. -% -% \subsection{File management} -% -% All macros in this section are expandable like -% the counterparts of the \LaTeX\ kernel. Also they -% can be used after the preamble. -% -% \subsubsection{File extensions} -% -% \begin{declcs}{ltx@clsextension}\\ -% \cs{ltx@pkgextension} -% \end{declcs} -% Macros \cs{ltx@clsextension} and \cs{ltx@styextension} -% stores the strings |cls| and |sty|. In opposite to \hologo{LaTeX}'s -% \cs{@clsextension} and \cs{@styextension} they can also be -% used after |\begin{document}|. -% -% \subsubsection{Load check} -% -% \begin{declcs}{ltx@ifclassloaded} \M{class} \M{yes} \M{no}\\ -% \cs{ltx@ifpackageloaded} \M{package} \M{yes} \M{no} -% \end{declcs} -% Macros \cs{ltx@ifclassloaded}\slash\cs{ltx@ifpackageloaded} -% execute \meta{yes}, if the \meta{class} or \meta{package} is loaded, -% otherwise \meta{no} is called. -% Both \meta{class} and \meta{package} are specified without -% extension. The macros can also be used after |\begin{document}|. -% -% \begin{declcs}{ltx@iffileloaded} \M{file} \M{yes} \M{no} -% \end{declcs} -% If \LaTeX's \cs{ProvidesFile} macro was called before -% using \meta{file} as argument, then \cs{ltx@iffileloaded} -% calls \meta{yes}, otherwise \meta{no}. -% Therefore it is possible -% that the \meta{file} is loaded, but \meta{no} is executed because -% of a missing \cs{ProvidesFile}. The \LaTeX\ kernel does not have -% a counterpart of \cs{ltx@iffileloaded}. -% -% Note that the file name used in \cs{ProvidesFile} and -% \cs{ltx@iffileloaded} must match. For example, if \TeX's -% default extension \xext{tex} was given in the first command, -% then it must also specified in the latter command and vice versa. -% -% \subsubsection{Version date check} -% -% \begin{declcs}{ltx@ifclasslater} \M{class} \M{date} \M{yes} \M{no}\\ -% \cs{ltx@ifpackagelater} \M{package} \M{date} \M{yes} \M{no}\\ -% \cs{ltx@iffilelater} \M{file} \M{date} \M{yes} \M{no} -% \end{declcs} -% If a \cs{ProvidesClass}\slash\cs{ProvidesPackage}\slash -% \cs{ProvidesFile} command with exact the same class\slash package\slash -% file was executed before with an optional -% argument that starts with a \LaTeX\ version date, then -% this version date is compared with the argument \meta{date}. -% If they are equal or if the version date is the later date, -% then \meta{yes} is called. In all other cases \meta{no} is executed. -% -% A \LaTeX\ date has the format |YYYY/MM/DD| with |YYYY| as year -% with four digits, |MM| as month with two digits and |DD| as day -% with two digits. If \pdfTeX's \cs{pdfmatch} is available, then -% it is used to detect the version date, to reject invalid -% date formats and to reject some invalid dates. -% Dates before 1994/01/01 are always invalid, because version -% dates are introduced with \LaTeXe\ in 1994. -% -% \subsection{Macro additions} -% -% \begin{declcs}{ltx@GlobalAppendToMacro} \M{cmd} \M{addition}\\ -% \cs{ltx@LocalAppendToMacro} \M{cmd} \M{addition} -% \end{declcs} -% The \meta{addition} is appended to the parameterless macro \meta{cmd}. -% If \meta{cmd} is undefined or has the meaning \cs{relax}, then -% it will be initialized as empty macro beforehand. Due to a bug \meta{addition} -% must not contain \cs{par} before version 2010/10/25 v1.9. -% -% \begin{declcs}{ltx@GlobalPrependToMacro} \M{cmd} \M{addition}\\ -% \cs{ltx@LocalPrependToMacro} \M{cmd} \M{addition} -% \end{declcs} -% The \meta{addition} is prepended to the parameterless macro \meta{cmd}. -% If \meta{cmd} is undefined or has the meaning \cs{relax}, then -% it will be initialized as empty macro beforehand. The macros -% were added in version 2011/08/22 v1.21. -% -% \subsection{Next character detection} -% -% \begin{declcs}{ltx@ifnextchar} \M{char} \M{yes} \M{no} -% \end{declcs} -% If next character is \meta{char} then \meta{yes} is called, -% otherwise \meta{no}. The character is not removed. -% Spaces are silently removed when looking for \meta{char} -% as \hologo{LaTeX}'s version \cs{kernel@ifnextchar} does. -% But there are also small differences: -% \begin{itemize} -% \item The space can be used as \meta{char}. In this case -% optional spaces before \meta{char} are not supported of course. -% \item If the optional space is a command that is a character -% (defined by \cs{let} or \cs{futurelet}), then -% \cs{kernel@ifnextchar} breaks with an \hologo{TeX} error. -% \cs{ltx@ifnextchar} silently removes this token as -% optional space. -% \end{itemize} -% Since 2010/03/01 v1.3. -% -% \begin{declcs}{ltx@ifnextchar@nospace} \M{char} \M{yes} \M{no} -% \end{declcs} -% Macro \cs{ltx@ifnextchar@nospace} behaves like -% macro \cs{ltx@ifnextchar} with the exception that -% optional spaces are not supported before \meta{char}. -% Since 2011/04/14 v1.19. -% -% \subsection{\cs{ltx@leavevmode}, \cs{ltx@mbox}} -% -% \begin{declcs}{ltx@leavevmode} -% \end{declcs} -% Macro \cs{ltx@leavevmode} calls \hologo{pdfTeX}'s \cs{quitvmode}. -% Otherwise \cs{leavevmode} is used and defined if it is necessary. -% -% \begin{declcs}{ltx@mbox} -% \end{declcs} -% Macro \cs{ltx@mbox} reimplements \cs{mbox} with two changes. -% Instead of \cs{leavevmode} it uses \cs{ltx@leavevmode} and -% stops right after \cs{hbox}. Especially it does not grab -% the argument and allows the extended syntax of \cs{hbox}. -% -% \subsection{Expandable test for emptiness} -% -% \begin{declcs}{ltx@ifempty} \M{stuff} \M{yes} \M{no} -% \end{declcs} -% Macro \cs{ltx@ifempty} checks in exact two expansion steps -% whether \meta{stuff} -% is empty or contains token. Depending on the result -% \meta{yes} or \meta{no} is executed. The token in \meta{stuff} -% may contain \cs{par} and unmatched conditionals (\cs{if}, \cs{else}, -% \cs{fi}, \dots). Since version 2010/11/12 v1.11. -% -% \begin{declcs}{ltx@ifblank} \M{stuff} \M{yes} \M{no} -% \end{declcs} -% Macro \cs{ltx@ifblank} tests in exact two expansion steps -% if \meta{stuff} is empty or contain only blank spaces. -% In this case argument \meta{yes} is called.

It stops stripping spaces -% after a token group in curly braces if the first two tokens -% inside the group are equal. -% \item -% Macro \cs{ltx@zapspace} also works with \cs{par} -% and conditionals (\cs{if}, \cs{else}, \cs{fi}, \dots). -% \end{itemize} -% Macro \cs{ltx@zapspace} is available since version -% 2010/12/07 v1.14. -% -% \subsection{Check for emptiness of boxes} -% -% \begin{declcs}{ltx@IfBoxEmpty} \M{box register number} -% \M{yes} \M{no} -% \end{declcs} -% Macro \cs{ltx@IfBoxEmpty} calls \meta{yes} if -% the box exists (\cs{ifvoid} returns false) and the box -% does not contain any content.
