The formatting for each cross-reference type can be fully % customised in the preamble of your document. In addition, % \package{cleveref} can type-set cross-references to lists of multiple % labels, automatically formatting them according to their types, % sorting them, and compressing sequences of numerically consecutive % labels. Again, the multiple-reference formatting is fully % customisable. % \end{abstract} % % \tableofcontents % \clearpage % % \section{Introduction} % When ``clever'' is used in the name of a computer program, it usually % signifies that the programmer is overly smug about his own % achievements! But at the heart of the \LaTeX{} philosophy is the idea % that it is clever to delegate as much of the typesetting as possible to % the computer, in order to achieve a beautiful --- and above all % consistent --- visual appearance. % % Both these probably apply to the \package{cleveref} package. Its goals % are two-fold: to exploit everything that \LaTeX{} inherently knows % about labels as intelligently as possible (clever processing); and to % enable you to produce an attractive, consistent formatting of % cross-references throughout your document, with the minimum of effort % (you'd be clever to use it!). % % The \package{cleveref} package enhances \LaTeX{}'s cross-referencing % facilities by allowing cross-references to be formatted automatically % according to the type of thing they refer to (chapter, section, % equation, theorem, etc.) and the context in which the cross-reference % is used. It can automatically format cross-references to multiple % labels, sort lists of multiple cross-references, compress % cross-references to consecutive labels into a reference range, and all % kinds of other clever wizardry. % % In standard \LaTeX{}, you have almost certainly found yourself writing % things like |Eq.~(\ref{eq1})| and |Theorems~\ref{thm1} to~\ref{thm3}| % over and over again. Tedium isn't the only downside to this. What % happens if you later decide you want equation references to be type-set % as |Equation~\ref{eq1}| instead (i.e.\ without the brackets)? What % happens if you decide to change the theorem labelled |thm1| into a % lemma? What if you move |thm3| so that it appears (and is numbered) % before |thm1|, so that references to both should be ordered % |Theorems~\ref{thm3} to~\ref{thm1}| (i.e.\ the other way around)? What % if you decide you prefer references to multiple theorems to be written % as |Theorems~\ref{thm1}--\ref{thm3}|? You have to search through the % entire \LaTeX{} source of your document, modifying all references to % equations, updating all references to |thm1|, re-ordering all % references to |thm1| and |thm3|, and changing the formatting of all % references to multiple theorems. % % The \package{cleveref} package allows you to define the format for % cross-references once-and-for-all in the preamble of your document. If % you later decide to change the format of equation references, you only % have to change one preamble definition. If you change a theorem into a % lemma, you don't need to change any cross-references at all, because % \package{cleveref} will automatically type-set cross-references to it % using the appropriate formatting. This makes it far easier to type-set % cross-references uniformly across your whole document, as well as % avoiding repetitively typing similar text for each and every % cross-reference. % % Given how useful this is, there are naturally a number of other % packages with similar goals, most notably \package{varioref}, % \package{fancyref}, \package{hyperref}'s |\autoref| command, and (for % theorem-like environments) \package{ntheorem} (with the \option{thref} % option). (There are many others, but these come closest to providing % similar features to \package{cleveref}.) However, all have certain % deficiencies which \package{cleveref} attempts to overcome. % % The \package{fancyref} package doesn't automatically determine the type % of thing being referred to. Instead, it relies on you adhering to a % naming convention for labels. This is usually a good idea in any case, % but it can be inconvenient. For example, if you change a theorem into a % lemma, you have to change the label name, and therefore also all % cross-references to it. So you are back to searching and replacing % through the entire document, not to mention missing out on all the % other \package{cleveref} features. % % The enhanced referencing feature provided by the \package{varioref} % package's\linebreak[4] |\labelformat| command decides how to format % cross-references when the label is \emph{defined}, rather than when it % is \emph{referenced}. Often this isn't a problem. But it makes it % impossible to format cross-references differently according the context % in which they are referenced, which can sometimes be very useful. For % example, if you want cross-references at the beginning of a sentence % formatted any other way than by capitalising the first letter of the % cross-reference text, it is impossible using % \package{varioref}. Perhaps even more significantly, it makes it % impossible to type-set multiple references automatically; you are back % to typing % % |Eqs.~(\ref{eq1}) to~(\ref{eq3})| by hand. Not to mention missing out % on automatic sorting and compressing of consecutive references, % \package{ntheorem} support, precise control over hyper-links, % etc. \package{cleveref} fully supports \package{varioref}, taking over % responsibility for type-setting cross-references, whilst retaining all % the \package{varioref} page-referencing magic. % % The \package{hyperref} package's |\autoref| command type-sets a name % before a cross-reference, determined by the cross-reference type. This % is less flexible than \package{cleveref}'s fully customisable % cross-reference formatting but, when combined with \package{varioref}, % the two packages working together come close. However, even with % \package{hyperref}, it is impossible to customise precisely which part % of the cross-reference is made into a hyper-link in PDF documents; this % is very easy with \package{cleveref}. And it still remains impossible % to type-set multiple references, have consecutive references sorted and % compressed automatically, etc. % % The \package{ntheorem} package (with the \option{thref} option) does % things right with regards how and when the format is defined\ldots % except that it only works for theorem-like environments. It is possible % to use it for other environments, but only in a bastardized form, by % manually supplying an optional argument to |\label| commands that % specifies the label type. \package{cleveref} works equally well when % referencing any type of thing, as well as fully supporting % \package{ntheorem}. And again, \package{cleveref} also provides a % number additional features over \package{ntheorem}, such as multiple % cross-references, automatic sorting and compressing of consecutive % cross-references, control over the placement of hyper-links, etc. % % % % \section{Usage} % The \package{cleveref} package is loaded in the usual way, by putting % the line % \begin{quote} % |\usepackage{cleveref}| % \end{quote} % in your document's preamble. However, care must be taken when using % \package{cleveref} in conjunction with other packages that modify % \LaTeX{}'s referencing system (see % \cref{sec:other_packages}). Basically, \package{cleveref} must be % loaded \emph{last}. % % If you just want to get going quickly with \package{cleveref}, and come % back later to read up on all the features it provides in more detail, % here's what you need to do. Wherever you would previously have used % |\ref|, use |\cref| instead. (Except at the beginning of a sentence, % where you should use |\Cref|.) You no longer need to put the name of % the thing you're referencing in front of the |\cref| command, because % \package{cleveref} will sort that out for you: i.e.\ use |\cref{eq1}| % instead of |eq.~(\ref{eq1})|. If you want to refer to a range of % labels, use the |\crefrange| command: |\crefrange{eq1}{eq5}| gives % |eqs.~(1) to~(5)|. Finally, if you want to refer to multiple things at % once, you can now combine them all into one cross-reference and leave % \package{cleveref} to sort it out: e.g.\ % |\cref{eq2,eq1,eq3,eq5,thm2,def1}| produces:% % |eqs.~(1) to~(3) and~(5),|\linebreak[4] |theorem~5, and definition~1|. % % % \section{Type-Setting Cross-References} % \label{sec:typesetting} % \DescribeMacro\cref % To automatically type-set a cross-reference according to the type of % thing referred to, simply refer to it using |\cref{|\meta{label}|}|. % \package{cleveref} imposes just one extra restriction on the names of % labels: they are no longer allowed to contain commas ``,''. These are % instead used to type-set multiple cross-references (see below). % % \DescribeMacro\Cref As it is very difficult\footnote{Actually, very % likely impossible!} for \LaTeX{} to determine whether a % cross-reference appears at the beginning of a sentence or not, a % beginning-of-sentence variant exists: |\Cref{|\meta{label}|}|. By % default, this type-sets the cross-reference with the first letter % capitalised, and without using an abbreviation in those cases where the % standard variant does use one. (However, the formatting of the |\cref| % and |\Cref| forms can be fully and independently customised, see % \cref{sec:customising}.) % % \DescribeMacro\ref % \package{cleveref} does \emph{not} modify the standard |\ref| % command\footnote{This is not quite true. The original \cmd{\ref} % command no longer works when \package{cleveref} is loaded, so % \package{cleveref} redefines it to recover the original behaviour.}, % so you can still use it to type-set the formatted label counter alone, % without any additional text or formatting. % % \DescribeMacro\crefrange % \DescribeMacro\Crefrange % To type-set a cross-reference range, e.g. |Eqs.~(1.1) to~(1.5)|, % use\linebreak[4] |\crefrange| or |\Crefrange| (depending on the % capitalisation you require), which take the beginning and end of the % range as arguments: % \begin{quote} % |\crefrange{|\meta{label1}|}{|\meta{label2}|}| % \end{quote} % % \DescribeMacro\cref % \DescribeMacro\Cref % To type-set multiple cross-references, simply list the lables inside % the |\cref| or |\Cref| command, separated by commas (you are not % allowed to use commas in label names when using \package{cleveref}): % \begin{quote} % |\cref{|\meta{label1}|,|\meta{label2}|,|\meta{label3}|,...}| % \end{quote} % % \DescribeMacro{\cref*} % \DescribeMacro{\Cref*} % \DescribeMacro{\crefrange*} % \DescribeMacro{\Crefrange*} % When \package{cleveref} is used along with the \package{hyperref} % package (see \cref{sec:customising,sec:other_packages}), additional % starred variants of all the referencing commands are available. The % standard referencing commands will make cross-references into % hyper-links; the starred variants prevent this, producing the same % type-set text but without creating hyper-links. % % % % \section{Sorting and Compressing} % \label{sec:sort&compress} % When \package{cleveref} type-sets lists of multiple cross-references, % the default behaviour is to automatically sort the list and compress % sequences of consecutive cross-references into a reference range. You % can change this behaviour by supplying one of the following package % options: % \begin{description} % \item[\option{sort}] Sort lists of cross-references, but don't compress % consecutive references. % \item[\option{compress}] Compress sequences of consecutive references % into a reference range, but don't sort the list of cross-references. % \item[\option{nosort}] Neither sort lists of cross-references, % \emph{nor} compress consecutive references. % \item[\option{sort\&compress}] Sort lists of cross-references, and % compress sequences of consecutive references into a reference % range (this is the default). % \end{description} % % Occasionally, you may want to prevent a particular sequence of % consecutive cross-references from being compressed to a reference % range, without disabling this feature globally. To achieve this, you % can separate the cross-references in the list by one or more empty % references, at the point at which you want to prevent compression. For % example, % \begin{quote} % |\cref{eq1,eq2,eq3,,eq4}| % \end{quote} % will be type-set as % \begin{quote} % eqs.~(1) to~(3) and (4) % \end{quote} % or % \begin{quote} % |\cref{eq1,eq2,,eq3,eq4,eq5,,eq6,eq7,eq8}| % \end{quote} % will be type-set as % \begin{quote} % eqs.~(1), (2), (3) to~(5) and (6) to~(8) % \end{quote} % You can safely put an empty reference between cross-references that % would never be compressed anyway; it will simply be ignored. % % If lists of cross-references are also being sorted (the default), it % can be a little confusing to work out where the empty reference should % go in order to prevent compression of a particular consecutive % sequence. It's best to think of the empty reference as being % ``attached'' to the cross-reference preceding it. When the list is % sorted, the empty reference will still appear after the same preceding % reference, and will prevent it being compressed with any subsequent % consecutive cross-references. In other words, an empty reference % ensures that the preceding reference will appear explicitly in the % final, type-set cross-reference: % \begin{quote} % |\cref{eq3,,eq2,eq1,eq6,eq4,eq5}| % \end{quote} % will be type-set as % \begin{quote} % eqs.~(1) to~(3) and (4) to~(6) % \end{quote} % % % % \section{Capitalising All Cross-Reference Names} % \label{sec:capitalise} % \DescribeMacro{capitalise} Many authors prefer to always capitalise % cross-reference names, regardless of where they appear in the sentence, % writing Theorem~1 and Equation~3 (as opposed to theorem~1 and % equation~3). If you count yourself among this group, you can pass the % \option{capitalise} option to the \package{cleveref} package % (\option{capitalize} also works). % % All the default cross-reference formats will then have the first letter % capitalised, as will the automatically generated |\cref| variants (see % \cref{sec:individual_customisation,sec:full-control_customisation}). % (However, if you explicitly define a |\cref| variant to \emph{not} be % capitalised, \package{cleveref} will still honour your definition. In % other words, you're responsible for defining the capitalisation % correctly in your own format definitions.) % % You should \emph{still} use the |\Cref| variants at the beginning of % sentences, for one thing, because abbreviations should not be used at % the beginning of a sentence\footnote{At least in English; I'm not sure % about other languages.}, and for another, in case you later change % your mind and remove the \option{capitalise} option. % % % % \section{Customising the Cross-Reference Format} % \label{sec:customising} % The \package{cleveref} package allows you to take full control of the % type-setting of cross-references, by allowing the formatting to be % customised. Defaults appropriate for English documents are provided for % the standard label types\footnote{For any pedantic classics scholars % out there: ``lemmas'' is recognised as a valid plural form of % ``lemma'' in all current versions of the Oxford English % Dictionary. ``Lemmata'' was last heard in a mathematical debate that % took place in a pub just around the corner from Hadrian's wall\dots a % few years before the Romans pulled out of Britain. \package{cleveref} % might have ``clever'' in its name, but even that doesn't make it % pretentious enough to use ``lemmata''.}, and support for German, % French, Spanish and Italian is provided via package options (see % \cref{sec:language_babel}). But if you don't like the defaults, or are % writing in a different language\footnote{Any contributions of % translations for missing languages are very welcome! See % \cref{sec:code:babel} for information on how to contribute % translations.}, or you need to refer to something for which no % default format is defined, then you can take charge and define your own % formats. % % If \package{cleveref} encounters a cross-reference to a type it does % not know, it will produce a ``reference type undefined'' warning, and % type-set the cross-reference as % \begin{quote} % {\bf ??}~|\ref{|\meta{label}|}| % \end{quote} % i.e.\ the label counter preceded by a double question mark. The error % message indicates the name of the unknown cross-reference type, which % you will then probably want to define. (References to undefined labels % still produce a ``reference undefined'' warning and appear as a double % question mark, as usual.) % % The cross-reference formats are usually constructed out of components: % the cross-reference name (different for each type of cross-reference), % the format for the label itself, and the conjunctions used in reference % ranges and lists of multiple cross-references. There are two levels of % customisation: you can either customise the components, or you can take % full control and override the component-derived format entirely. % % % \subsection{Customising the Cross-Reference Components} % \label{sec:component_customisation} % % \subsubsection{Global Customisation} % \label{sec:global_customisation} % The global customisation commands affect all cross-reference formats, % unless they are overridden by lower-level customisation commands. % % \DescribeMacro\crefdefaultlabelformat % The format for the label counter itself can be customised globally % using % \begin{quote} % |\crefdefaultlabelformat{|\meta{format}|}| % \end{quote} % The \meta{format} argument can be any valid \LaTeX{} code, though you % will need to |\protect| fragile commands. It can (and almost certainly % should!) contain three arguments, |#1|, |#2| and |#3|. The first % argument is the formatted version of the label counter (e.g.\ % |\theequation|). The other two are used to mark the beginning and end % of the part of the cross-reference that should form the hyper-link when % the \package{hyperref} package is used (see % \cref{sec:other_packages}). The hyper-link arguments |#2| and |#3| % \emph{must} appear in that order. (Leaving them out completely will not % cause an error, but in that case no hyper-link will be created when % \package{hyperref} is used, and there are better ways to achieve % this. See \cref{sec:typesetting,sec:other_packages}.) % % Note that the default format for equation cross-references already % overrides \cmd{\crefdefaultlabelformat} in order to surround the label % by brackets, so the redefining |\crefdefaultlabelformat| will have no % effect on equations. The label format for equations must be customised % separately if you want to change it (see % \cref{sec:individual_customisation}). % % \DescribeMacro\crefrangeconjunction % The conjunction used in a reference range can be customised by % defining |\crefrangeconjunction|: % \begin{quote} % |\newcommand{\crefrangeconjunction}{|\meta{conjunction}|}| % \end{quote} % It does not have to be an actual conjunction in the linguistic sense, % e.g.\ it is perfectly reasonable to define it to be an emdash % ``|--|''. |\crefrangeconjunction| is used directly between the start % and end references in a reference range, without any additional space % surrounding it, e.g.\ |\crefrange{thm1}{thm2}| is type-set as % \begin{quote} % |theorems~\ref{thm1}\crefrangeconjunction\ref{thm2}| % \end{quote} % so you may or may not want to include surrounding space, depending on % the formatting you desire. For example, % \begin{quote} % |\newcommand{\crefrangeconjunction}{ and~}| % \end{quote} % does require surrounding space, whereas % \begin{quote} % |\newcommand{\crefrangeconjunction}{--}| % \end{quote} % does not. % % \DescribeMacro\crefrangepreconjunction % \DescribeMacro\crefrangepostconjunction % There are two other ``conjunction'' commands available for customizing % the formating for reference ranges. These are % |\crefrangepreconjunction| and |\crefrangepostconjunction|, which % insert text before the first label defining the range, and after the % second label, respectively. For example, when these commands are % defined, |\crefrange{thm1}{thm2}| is type-set as % \begin{quote} % |theorems~\crefrangepreconjunction\ref{thm1}|\\ % | |\ding{229} |\crefrangeconjunction\ref{thm2}\crefrangepostconjunction| % \end{quote} % These commands are not used in the default English format definitions, % but they are needed in some languages to correctly express a range. For % example, the Italian format defines |\crefrangepreconjunction| to be % ``da'', so that |\crefrange{thm1}{thm2}| produces % \begin{quote} % |teorema da~\ref{thm1} a~\ref{thm2}| % \end{quote} % % \DescribeMacro\crefpairconjunction % \DescribeMacro\crefmiddleconjunction % \DescribeMacro\creflastconjunction % The conjunctions used in lists of multiple cross-references can be % customised by defining the commands |\crefpairconjunction|, % |\crefmiddleconjunction| and |\creflastconjunction|: % \begin{quote} % |\newcommand{\crefpairconjunction}{|\meta{conjunction}|}|\\ % |\newcommand{\crefmiddleconjunction}{|\meta{conjunction}|}|\\ % |\newcommand{\creflastconjunction}{|\meta{conjunction}|}| % \end{quote} % |\crefpairconjunction| is used when there are only two cross-references % in the list, |\creflastconjunction| is used between the penultimate and % final cross-reference in a list of more than two, and % |\crefmiddleconjunction| is used between all the others. Again, they do % not have to be conjunctions in the linguistic sense, and the same % considerations about surrounding space apply as in the case of % |\crefrangeconjunction|. For example, the default definition of % |\crefmiddleconjunction| is: % \begin{quote} % |\newcommand{\crefmiddleconjunction}{, }| % \end{quote} % % \DescribeMacro\crefpairgroupconjunction % \DescribeMacro\crefmiddlegroupconjunction % \DescribeMacro\creflastgroupconjunction % By default, the conjunctions used to separate sub-lists of different % cross-reference types in a multi-reference are identical to those used % to separate cross-references of the same type\footnote{More accurately, % if you redefine $\backslash$crefpairconjunction etc.\ in your % preamble, $\backslash$crefpairgroupconjunction etc.\ are % automatically redefined so that they match. (In some languages, the % default definition of $\backslash$creflastgroupconjunction has an % additional comma lacking in $\backslash$creflastconjunction.)}. You % can override this by defining the conjunction commands % |\crefpairgroupconjunction|, |\crefmiddlegroupconjunction| and % |\creflastgroupconjunction|. % % For example, % \begin{quote} % |\cref{eq1,eq2,eq3,thm1,thm2,fig1,thm3}| % \end{quote} % is type-set as % \begin{quote} % eqs.~(1)|\crefrangeconjunction|(3)|\crefmiddlegroupconjunction|%\\ % theorems~1|\crefpairconjunction|2|\crefmiddlegroupconjunction|%\\ % fig.~1|\creflastgroupconjunction{}|theorem~3 % \end{quote} % % % \subsubsection{Customising Individual Cross-Reference Types} % \label{sec:individual_customisation} % \DescribeMacro\crefname % \DescribeMacro\Crefname % The cross-reference name for a given cross-reference type is customised % using the |\crefname| and |\Crefname| commands: % \begin{quote} % |\crefname{|\meta{type}|}{|\meta{singular}|}{|\meta{plural}|}|\\ % |\Crefname{|\meta{type}|}{|\meta{singular}|}{|\meta{plural}|}| % \end{quote} % used by the |\cref| and |\Cref| commands, respectively. You must supply % both \meta{singular} and \meta{plural} forms of the name. If the % corresponding |\Crefname| is undefined when |\crefname| is called, it % will automatically define |\Crefname| to be a capitalised version of % |\crefname|, using |\MakeUppercase|. Conversely, if the corresponding % |\crefname| is undefined when |\Crefname| is called, it will % automatically define |\crefname| to be a lower-case version of % |\Crefname|, using |\MakeLowercase|. Obviously, this will only work % properly if the names begin with a letter. If the first letter is a % special character construct, such as an accented character, you will % need to surround it by braces. If the first thing in the name is % \emph{not} a letter at all (e.g.\ if it is a \LaTeX{} command), you % \emph{must} define both capitalisation variants explicitly. Otherwise % you will get strange and fatal errors when processing the document. % % The cross-reference \meta{type} is usually the name of the counter for % the environment (equation, chapter, section, etc.). The exceptions are % appendices, labels whose type has been overridden explicitly by % supplying an optional argument (see \cref{sec:label_type}), and % theorem-like environments when the \package{ntheorem} package is % loaded, for which \meta{type} should instead be the environment name % (lemma, corollary, definition, etc.) even when different environments % are part of the same numbering sequence. (\package{ntheorem} provides % extra information about the environment when different theorem-like % environments share a common counter, which \package{cleveref} makes use % of to distinguish between them automatically.) In the case of % appendices, the \meta{type} is ``appendix'' for the top-level % sectioning command (\cmd{\chapter} or \cmd{\section}, depending on the % document class), ``subappendix'' for the sectioning command one level % below (\cmd{\section} or \cmd{\subsection}), ``subsubappendix'' for the % next level of sectioning command, etc. % % For convenience, if they have not been otherwise customised by the end % of the preamble, the cross-reference name (and label format) for % |subsection| is by default inherited from that of |section|, and that % of |subsubsection| is inherited from |subsection| (which might itself % have been inherited from |section|). Similarly for |subappendix|, % |subsubappendix| and |subsubsubappendix|, and also for |enumii|, % |enumiii|, |enumiv| and |enumv|. Finally, |subfigure| and |subtable| % inherit from |figure| and |table|, respectively. % % \DescribeMacro\creflabelformat % You may want the label format for a particular cross-reference type to % differ from the global format set by |\crefdefaultlabelformat| (see % \cref{sec:global_customisation}). You can do this using % \begin{quote} % |\creflabelformat{|\meta{type}|}{|\meta{format}|}| % \end{quote} % The \meta{type} argument is the cross-reference type to customise, and % the \meta{format} argument defines the label format for % cross-references of that type. As in the case of\linebreak[4] % |\crefdefaultlabelformat|, the latter should contain the three % arguments |#1|, |#2| and |#3|, the first being the formatted version of % the label counter, the others determining the beginning and end of the % portion that becomes a hyper-link when the \package{hyperref} package % is loaded (see \cref{sec:other_packages}). |#2| and |#3| \emph{must} % appear in that order. % % \DescribeMacro\crefrangelabelformat % Normally, the start and end references in a reference range are % type-set using the usual label format (as defined by % |\crefdefaultlabelformat| or |\creflabelformat|) separated by % |\crefrangeconjunction| (\cref{sec:global_customisation}). You can % override this for a given cross-reference type using % \begin{quote} % |\crefrangelabelformat{|\meta{type}|}{|\meta{format}|}| % \end{quote} % The \meta{format} argument should contain six arguments: |#1|, |#2|, % |#3|, |#4|, |#5|, |#6|. The first two (|#1| and |#2|) are the formatted % versions of the two label counters defining the reference range. The % next two (|#3| and |#4|) denote the beginning and end of the hyper-link % for the first reference, the final two (|#5| and |#6|) the hyper-link % for the second reference. The hyper-link arguments \emph{must} appear % in order. For example, % \begin{quote} % |\crefrangelabelformat{equation}{(#3#1#4) to~(#5#2#6)}| % \end{quote} % % % \subsection{Low-Level Customisation: Taking Full Control} % \label{sec:full-control_customisation} % If you need more precise control over the cross-reference format than % is possible by customising the individual components, then you can take % full control of the format for any given type, overriding the % component-derived format entirely. The formats for single % cross-references, reference ranges and multi-references are customised % separately. If you only customise some of these, the other formats will % be constructed from components, as usual. % % Note that when deciding which cross-references should be grouped % together for sorting and/or compressing, \package{cleveref} does % something slightly more complicated than simply checking whether the % reference types match. In fact, it checks whether the reference % \emph{formats} match\footnote{To be precise, \package{cleveref} checks % whether the $\backslash$|crefformat|'s match.}. This will always be % the case for cross-references of the same type. But it could also be % the case for cross-references that have different types, if the % cross-reference formats happen to be identical. % % The reason for doing this is to allow cross-references to e.g.\ % sections and subsections to be grouped together if they have identical % formats. The default formats for the sectioning commands, figures and % subfigures, tables and subtables, and enumerated lists are set up in % this way. If you change any of them using the low-level customisation % commands, but still want them to be grouped together, then you must % ensure that the formats are \emph{identical}. (It is \emph{not} % sufficient for the formats to produce identical type-set text; the % format definitions must contain identical \LaTeX{} code.) % % % \subsubsection{Single Cross-References} % \label{sec:ref_format} % \DescribeMacro\crefformat % \DescribeMacro\Crefformat % Cross-reference formats for \emph{single} cross-references are defined or % redefined using the\linebreak[4] |\crefformat| and |\Crefformat| % commands, which are used by the |\cref| and |\Cref| commands % respectively. These take two arguments: the cross-reference type, and the % formatting code: % \begin{quote} % |\crefformat{|\meta{type}|}{|\meta{format}|}|\\ % |\Crefformat{|\meta{type}|}{|\meta{format}|}| % \end{quote} % The \meta{type} is usually the name of the counter, except for labels % whose type has been overridden explicitly (see \cref{sec:label_type}), % theorem-like environments when \package{ntheorem} is loaded, in which % case it is the environment name, and appendices. For the latter, the % \meta{type} is ``appendix'' for the top-level sectioning command % (\cmd{\chapter} or \cmd{\section}, depending on the document class), % ``subappendix'' for the sectioning command one level below % (\cmd{\section} or \cmd{subsection}), ``subsubappendix'' for the next % level of sectioning command, etc. % % As in the case of the |\crefname| and |\Crefname| commands, if the % corresponding |\Crefformat| is undefined when |\crefformat| is called, % it will define the |\Crefformat| to produce a capitalised version of % |\crefformat|, using |\MakeUppercase|. Conversely, if the corresponding % |\crefformat| is undefined whe |\Crefformat| is called, it will define % the |\crefformat| to produce a lower-case version of |\Crefformat|, % using |\MakeLowercase|. Obviously, this will only work properly if the % format starts with a letter, and letter constructs (such as accented % letter constructs) must be surrounded by braces (see % \cref{sec:global_customisation}). % % The \meta{format} argument can be any valid \LaTeX{} code, though you % will need to |\protect| fragile commands. It should contain three % arguments, |#1|, |#2| and |#3|. The first argument is the formatted % version of the label counter (e.g.\ |\theequation|). The other two are % used to mark the beginning and end of the part of the cross-reference % that forms the hyper-link when the \package{hyperref} package is used, % and \emph{must} appear in that order (see \cref{sec:other_packages}). % % As an example, % \begin{quote} % |\crefformat{equation}{Eq.~(#2#1#3)}| % \end{quote} % will type-set equation references as % \begin{quote} % Eq.~(\meta{counter}) % \end{quote} % with the counter (excluding the brackets) forming the hyper-link. % % Note that the hyper-link arguments are \emph{not} letters, so if |#2| % appears at the beginning of \meta{format}, \package{cleveref} will not % be able to automatically define the other capitalisation variant % automatically using |\MakeUppercase| or |\MakeLowercase|. In this case, you % will have to define both variants separately. For example, if you % wanted to the ``Eq.'' to be part of the hyper-link, you would have to % define: % \begin{quote} % |\crefformat{equation}{#2eq.~(#1)#3}|\\ % |\Crefformat{equation}{#2Eq.~(#1)#3}| % \end{quote} % % % \subsubsection{Reference Ranges} % \label{sec:ref_range_format} % \DescribeMacro\crefrangeformat % \DescribeMacro\Crefrangeformat % The format for reference ranges is defined by |\crefrangeformat| % and\linebreak[4] |\Crefrangeformat|. Like |\creformat| and % |\Crefformat|, the commands take two arguments: the cross-reference % type, and the formatting code. % \begin{quote} % |\crefrangeformat{|\meta{type}|}{|\meta{format}|}|\\ % |\Crefrangeformat{|\meta{type}|}{|\meta{format}|}| % \end{quote} % The same comments apply as in the case of single cross-references: the % \meta{type} is usually the name of the counter, except for appendices, % labels with explicitly overridden types, and theorem-like environments % when \package{ntheorem} is loaded. Again, if the other-capitalisation % variant is not already defined, it will be defined automatically. % % The \meta{format} argument can again be any valid \LaTeX{} code, with % fragile commands |\protect|ed. However, this time it should contain % \emph{six} arguments, |#1|--|#6|. The first two (|#1| and |#2|) are the % formatted versions of the label counters, the next two (|#3| and |#4|) % are used to mark the beginning and end of the hyper-link for the first % cross-reference, and the final two (|#5| and |#6|) mark the beginning % and end of the second cross-reference's hyper-link. % % As an example, % \begin{quote} % |\crefrangeformat{equation}{eqs.~(#3#1#4) to~(#5#2#6)}| % \end{quote} % would type-set equation reference ranges as % \begin{quote} % eqs.~(\meta{counter1}) to~(\meta{counter2}) % \end{quote} % with the counters (excluding the brackets) forming the hyper-links. % % % \subsubsection{Multiple Cross-References} % \label{sec:multiple_ref_format} % \DescribeMacro\crefmultiformat % \DescribeMacro\Crefmultiformat % \DescribeMacro\crefrangemultiformat % \DescribeMacro\Crefrangemultiformat % The format for multiple cross-references is defined by % |\crefmultiformat| and\linebreak[4] |\Crefmultiformat|, and that of % reference ranges within multiple cross-references by % |\crefrangemultiformat| and |\Crefrangemultiformat|. Multi-references % also require \emph{all} the other cross-reference formats to be defined % (see \cref{sec:ref_format,sec:ref_range_format}), including the single % reference range formats, even if you never use the |\crefrange| and % |\Crefrange| commands. % % The commands all take five arguments: the cross-reference type, the % format for the first cross-reference in a list, the format for the % second cross-reference in a list of two, the format for the middle % cross-references in a list of more than two, and the format for the % last cross-reference in a list of more than two. % \begin{quote} % |\crefmultiformat{|\meta{type}|}{|\meta{first}|}{|\meta{second}|}{|\meta{middle}|}{|\meta{last}|}|\\ % |\Crefmultiformat{|\meta{type}|}{|\meta{first}|}{|\meta{second}|}{|\meta{middle}|}{|\meta{last}|}|\\ % |\crefrangemultiformat{|\meta{type}|}{|\meta{first}|}{|\meta{second}|}{|\meta{middle}|}{|\meta{last}|}|\\ % |\Crefrangemultiformat{|\meta{type}|}{|\meta{first}|}{|\meta{second}|}{|\meta{middle}|}{|\meta{last}|}| % \end{quote} % % The \meta{type} is, as ever, the counter name, except for appendices, % explicitly overridden label types, and theorem-like environments then % the \package{ntheorem} package is loaded. The same considerations apply % to the formatting arguments \meta{first}, \meta{second}, \meta{middle} % and \meta{last} as for the \meta{format} argument of |\crefformat| or % |\crefrangeformat|, including the meaning of the arguments that should % appear in the formatting code (|#1|, |#2| and |#3| for % |\crefmultiformat| and |\Crefmultiformat|, |#1|--|#6| for % |\crefmultiformat| and |\Crefmultiformat|). However, when the % corresponding other-capitalisation variant is automatically defined, % only the first letter of the \meta{first} argument is upper- or % lower-cased; the other arguments are defined to be identical for both % variants. % % Be careful to get the spaces at the beginning and end of the formatting % code correct: the \meta{first} and \meta{second}, or \meta{first}, % \meta{middle} and \meta{last}, \LaTeX{} code is type-set one after % another in a multi-reference, with no space separating them. You may or % may not want spaces at the beginning and end of the formatting code, % depending on the formatting you desire. For example, in the default % equation format: % \begin{quote} % |\crefmultiformat{equation}{eqs.~(#2#1#3)}%|\\ % | { and~(#2#1#3)}{, (#2#1#3)}{ and~(#2#1#3)}| % \end{quote} % the \meta{middle} argument should \emph{not} have a space at the % beginning, whereas the \meta{second} and \meta{last} arguments % \emph{should} have a space. % % % % \subsection{Language and \package{babel} support} % \label{sec:language_babel} % \package{cleveref} supports different languages via package options, in % the usual way, though not all languages are supported % yet\footnote{Currently, only \option{english}, \option{german}, % \option{ngerman}, \option{french}, \option{spanish} and % \option{italian} are supported. Contributions of translations for % missing languages are very welcome! See \cref{sec:code:babel} for % information on how to contribute translations.}. The \package{babel} % package is also supported when it is loaded, allowing you to change % language using the \package{babel} language switching commands such as % \cmd{\selectlanguage} and \cmd{\foreignlanguage}. % % The \package{babel} support works by redefining the cross-reference % names and conjunctions for the default cross-reference types. Any % customisations you make to the default cross-reference names and % conjunctions \emph{in the preamble} apply to the main language (i.e.\ % the last language listed in the options). A \cmd{\selectlanguage} % command or similar will override these customisations, replacing them % with the defaults for the new language. If you later use % \cmd{\selectlanguage} to switch back to the main language, your % customisations will be restored. If you want to customise % cross-reference names or conjunctions for any language other than the % main one, you either have to explicitly redefine them after every % language switching command, or hook the redefinitions into % \package{babel}'s language switching mechanism. (See % \cref{sec:code:babel} and the \package{babel} documentation.) % % If you have defined formats for new cross-reference types for which no % defaults are provided, then you're on your own. \package{cleveref} will % not know how to redefine them for other languages, and again you will % have to take care of it yourself, either by explicitly redefining them % in your document after each language switch, or by hooking the % redefinitions into \package{babel}'s language switching mechanism. % % On the other hand, since the language switching commands only modify % the cross-reference components, if you use the low-level customisation % commands to take full control of the format for a particular % cross-reference type, then (unless you're careful) you take it out of % the control of \package{babel} entirely. If you want to use the % low-level customisation commands, but \emph{do} still want the language % switching commands to work, then you have to use the component macros % in your customised formats. The cross-reference names are stored in % macros called |\cref@\meta{type}@name|, |\Cref@\meta{type}@name|, % |\cref@\meta{type}@name@plural|, and % |\Cref@\meta{type}@name@plural|.\linebreak[4] (Note that since these % macro names contain the ``@'' character, you must use % \cmd{\makeatletter} and \cmd{\makeatother} to access them.) % % For example, if you wanted to redefine the equation format so that the % cross-reference name (``equation'') was also part of the hyper-link, % but you still want to be able to switch language using \package{babel}, % you would need something like: % \begin{quote} % |\makeatletter|\\ % |\crefformat{equation}{#2\cref@equation@name~(#1)#3}|\\ % \dots\\ % |\makeatother| % \end{quote} % and similarly for \cmd{\crefrangeformat}, \cmd{\crefmultiformat}, % \cmd{\Crefformat}, etc. % % % % \section{Overriding the Cross-Reference Type} % \label{sec:label_type} % \DescribeMacro\label % As described previously, a label's ``type'' is usually determined by % its counter, or in the case of \package{ntheorem} theorem-like % environments by the environment name. Occasionally, you may want to % override the cross-reference type for a particular label. You can do % this by supplying the desired type as an optional argument to the % |\label| command: % \begin{quote} % |\label[|\meta{type}|]{|\meta{label}|}| % \end{quote} % % One circumstance in which is useful is when you want to define a % special cross-reference format for certain labels of a given type. By % supplying a type that doesn't already exist as the optional argument to % |\label|, you can then define the cross-reference format for that new % type in whatever way you like, without affecting other cross-references % of the same type. For example, if a particular equation contains % multiple expressions and you want it to always be referred to in the % plural, you could use: % \begin{quote} % |\crefname{pluralequation}{eqs.}{eqs.}|\\ % \dots\\ % |\label[pluralequation]{eq1}| % \end{quote} % You can of course reuse this format for other plural equations, too. % % If you need to do this frequently, it can become tedious specifying the % label explicitly each time. An alternative is to use the % \package{aliascnt} package. This lets you define one counter to be an % alias for another, so that effectively the same counter has two % names. Since \package{cleveref} determines the label type from the % counter name, the two counter aliases can have different % cross-reference formats whilst really being the same counter. You have % to somehow arrange for the correct counter alias to be used depending % on which cross-reference format you want (probably by defining two % variants of the environment in question). But the effort involved might % be worth the convenience of not having to remember to pass an explicit % optional argument to a large number of labels. % % You can use this trick to get different cross-reference formats for % different theorem-like environments, \emph{without} using the % \package{ntheorem} package\footnote{This trick seems to belong to % \LaTeX{} mythology, and certainly isn't my own idea! But I haven't % been able to definitively track down who originally came up with % it.}. For example, % \begin{quote} % |\usepackage{aliascnt}|\\ % |\usepackage{cleveref}|\\ % |\newaliascnt{lemma}{theorem}|\\ % |\newtheorem{lemma}[lemma]{Lemma}|\\ % |\aliascntresetthe{lemma}|\\ % |\crefname{lemma}{lemma}{lemmas}| % \end{quote} % % % % \section{Poor Man's \package{cleveref}} % Sometimes you may need to send your \LaTeX{} source to someone who % can't or won't install the \package{cleveref} package themselves. For % example, many academic journals accept papers in \LaTeX{} format, but % only support a small subset of the packages available on CTAN. The % \option{poorman} option was designed specifically to help in this % situation. % % When the \option{poorman} option is supplied, your document will be % processed as normal. But in addition, a |sed| script will automatically % be written, containing rules for replacing all the \cmd{\cref} commands % with the \LaTeX{} code that they would produce, and using the standard % \cmd{\ref} command to produce the cross-references themselves. I.e.\ % the script rewrites your document as you would have done if you had had % to do it manually! % % The advantage, of course, is that you \emph{don't} have to do it % manually. Instead, you can use all the features of \package{cleveref}, % and once you've created a version of your document that you want to % send elsewere, you can process it through the |sed| script to % completely remove the \package{cleveref} dependency. The recipient % won't even realise you used \package{cleveref}! % % The |sed| script is written to the same directory as the (main) % \LaTeX{} source file, and given the same name as that source file but % with the extension \file{.sed}. To process your document through the % script, all you need to do is run the following from your shell: % \begin{quote} % sed -f \meta{name}\file{.sed} \ % \meta{name}\file{.tex} \textgreater \meta{newname}\file{.tex} % \end{quote} % where \meta{name} is the name of the file containing your \LaTeX{} % source file minus the \file{.tex} extension, and \meta{newname} is % whatever you want to call the new version. \emph{Do not} make % \meta{newname} the same as \meta{name}: it won't work. (It's in any % case wise to keep the original \LaTeX{} source file containing the % \package{cleveref} commands, in case you need to produce an updated % version of your document in the future. Think of the % \meta{newname}\file{.tex} file in the same way as a \file{DVI} file: % something you can always reproduce from the original source.) % % If your document is composed of a number of separate \LaTeX{} source % files, combined with |\include| commands, only one |sed| script will be % generated, but you will need to run \emph {each} source file through % that \emph{same} script (and probably modify the |\include| commands to % match the new file names). However, using \package{babel}'s language % switching commands in a document split across multiple separate source % files is beyond the capabilities of the \package{poorman} option. You % will almost certainly need to manually tweak the |sed| script in that % case. % % Note that the \option{poorman} script cannot fully reproduce the % type-setting of the original \package{cleveref} cross-references in all % cases\footnote{At least, not without resorting to inserting low-level % \LaTeX{} code in your document, which would somewhat defeat the % purpose of the \option{poorman} option.}. In particular, any % customisation of hyper-links will be lost, and if you're using % \package{varioref} with the \option{legacyvarioref} option (see % \cref{sec:other_packages}, the spacing before the \cmd{\vref} command % will not be correct. % % % % \section{Interaction with Other Packages} % \label{sec:other_packages} % The \package{cleveref} package \emph{must} be loaded \emph{after} all % other packages that don't specifically support it\footnote{At the time % of writing, I'm not aware of any that do.}, i.e.\ the % \begin{quote} % |\usepackage{cleveref}| % \end{quote} % line should always be the last |\usepackage| command in your document's % preamble. % % Since \package{cleveref} redefines many internal commands involved in % \LaTeX{}'s cross-referencing system, it can interact badly with other % packages that do the same. The \package{fancyref} package, % \package{ntheorem}'s \option{thref} option, and \package{varioref}'s % |\labelformat| command, are incompatible with \package{cleveref}. (Note % that \package{varioref} \emph{is} fully supported by % \package{cleveref}, just that \package{cleveref}'s features supersede % \package{varioref}'s |\labelformat| feature.) However, since % \package{cleveref} implements a significantly enhanced version of these % packages' features, this is not really a problem. % % \DescribeMacro{\thref} % \DescribeMacro{\vref} % \DescribeMacro{\Vref} % \DescribeMacro{\vrefrange} % \DescribeMacro{\Vrefrange} % \DescribeMacro{\fullref} % \DescribeMacro{\Fullref} % In fact, if \package{ntheorem} is loaded with the \option{thref} % option, \package{cleveref} redefines \package{ntheorem}'s |\thref| % command for you, to be an alias for |\cref|.

You can % continue to use the other \package{varioref} and \package{ntheorem} % commands (other than |\labelformat| and the \option{thref} option) % whilst using \package{cleveref}, as long as \package{cleveref} is % loaded \emph{last}. % % \DescribeMacro{\vref*} % \DescribeMacro{\Vref*} % \DescribeMacro{\vrefrange*} % \DescribeMacro{\Vrefrange*} % \DescribeMacro{\fullref*} % \DescribeMacro{\Fullref*} % Note that, whilst in the business of redefining the \package{varioref} % commands, \package{cleveref} seizes the opportunity to get rid of the % irritating spacing behaviour of the \cmd{\vref} and \cmd{\Vref} % commands, instead making it consistent with the other % \package{cleveref} cross-referencing commands. This also frees up the % starred variants to be used to suppress hyper-links when the % \package{hyperref} package is loaded, as usual.

For example, if French % \package{babel} support is loaded, the commonly used ``:'' in label % names will often fail, spewing the usual random selection of % mysterious TeX errors that accompany such deep-seated errors. The % solution is to avoid using active characters in label names. (You may % need to consult e.g.\ the \package{babel} documentation to discover % which active characters are defined in your language.) % \item \package{cleveref} assumes that counters are only ever reset by % the standard sectioning commands (|\chapter|, |\section|, etc.). If % this is not the case, the automatic compression of consecutive % cross-references into a reference range may be incorrect. Making this % more flexible would be a simple task, but so far there doesn't seem % to be much need for it. % \item \package{cleveref} breaks \package{hyperref}'s \option{backref} % option, and probably also the \package{backref} package when used as % a stand-alone package. (This should be fixed in a future version.) % \item \package{cleveref} is almost certainly incompatible with % \package{titleref}, \package{byname}, \package{nameref} and the % like. This shouldn't be difficult to fix, and if you want this % feature, then\dots patches are always welcome! (Note that % \package{cleveref} \emph{is} compatible with \package{hyperref}, % despite that fact that this loads \package{nameref} % automatically. It's just that the \package{nameref} features won't % work.) % \item Given all the above, it's not surprising that \package{cleveref} % is incompatible with the \package{memoir} class, which incorporates % many of the above packages. There are some reports of some versions % of \package{cleveref} partially working with \package{memoir}, but % this should not be considered reliable. Compatibility with % \package{memoir} will become a realistic possibility once % compatibility with the other packages (listed above) is added. % \item \package{cleveref} doesn't know about the \package{subfloat} % package, so you have to revert to using \cmd{\ref} for % cross-references to sub-figures. (This should be fixed in a future % version.) % \item The \option{poorman} |sed| script loses any custom % \package{cleveref} hyper-link formatting you might have defined, and % does not reproduce the original spacing around the \cmd{\vref} % command when \package{varioref} is used with the % \option{legacyvarioref} option. This is not a bug; it is a % side-effect of the intended purpose of the \option{poorman} % option. The philosophy behind \option{poorman} is to replace % \package{cleveref}'s enhanced cross-referencing with standard % \LaTeX{} cross-reference commands that are guaranteed to work with % any standard \LaTeX{} installation. Although it would be simple to % fix these ``bugs'', it's almost certainly impossible without using % low-level \LaTeX{} code that is unlikely to be supported by journals, % thereby defeating the whole purpose of the \option{poorman} option. % \end{itemize} % % % \subsection{Possible Improvements} % In no particular order: % \begin{itemize} % \item The \option{poorman} option could be enhanced to allow a choice % of scripting language rather than just |sed| (e.g.\ |awk|, |perl|, % \dots?), but these are unlikely to be much better for those apt to % complain about the use of |sed|. The portable option would be to % output a \TeX{} ``script'', but this would be \emph{much} more % work\footnote{\LaTeX{} \emph{really} isn't suited to that kind of % pattern matching task -- just take a look at the code for escaping % regexp special characters in this package!} than I'm prepared to % invest. % \end{itemize} % % % % \section{Thanks} % A number of people have helped improve \package{cleveref} by % contributing code and translations.

(If I missed someone, please let me know!) % % % \StopEventually{\clearpage\PrintChanges\clearpage\PrintIndex} % % % \clearpage % \section{Implementation} % Essentially, the core of the implementation consists of causing an % extra piece of information -- the label ``type'' -- to be written to % the aux file, and defining \cmd{\cref} commands which use this extra % information to type-set the reference. % % The least invasive implementation of this kind of thing seems to be % that used by the \package{varioref} package. Namely, to redefine the % \cmd{\refstepcounter} command so that the \cmd{\@currentlabel} macro, % which usually just contains the type-set version of the counter, now % contains the additional type information. (In fact, we write three % extra pieces of information: the type, the counter value itself, and % the value of the counter that causes the label's counter to be reset, % which we call the ``prefix'' from now on.) \cmd{\@currentlabel} % eventually gets written to the aux file as an argument to % \cmd{\newlabel} by the usual \LaTeX{} mechanisms. This involves less % hacking to get everything else working again, since very few macros % other than \cmd{\ref} rely on this particular \cmd{\newlabel} argument % (nor are other packages likely to, given that \package{varioref} plays % around with it and is a \texttt{required} \LaTeX{} package). % % % \subsection{Redefinitions of \LaTeX{} kernel macros} % \begin{macro}{\refstepcounter} % \begin{macro}{\@currentlabel} % \begin{macro}{\cref@old@refstepcounter} % We store the original \cmd{\refstepcounter} in % \cmd{\cref@old@refstepcounter}, then redefine \cmd{\refstepcounter} % so that it first calls the old version before adding the extra % information to \cmd{\@currentlabel}.

If you can contribute definitions for a missing language, % ideally you should add them below the existing ones (using those as a % model), generate a patch against the original \package{cleveref.dtx} % file, and send the patch by email to the package author. However, if % you don't know how to produce a patch, you can instead just send the % translations as a plain text file. % % % \begin{macro}{\crefdefaultlabelformat} % \begin{macro}{\creflabelformat} % We first define the default label formats, which don't depend on % language. We override the default format for equations, to follow the % near universal convention of enclosing equation labels in brackets. % \begin{macrocode} \crefdefaultlabelformat{#2#1#3} \creflabelformat{equation}{\textup{(#2#1#3)}} % \end{macrocode} % \end{macro} % \end{macro} % % \begin{macro}{\cref@addto} % Utility macro to use instead of \package{babel}'s flawed \cmd{\addto} % (copied and modified from \package{varioref}). % \begin{macrocode} \def\cref@addto#1#2{% \@temptokena{#2}% \ifx#1\undefined% \edef#1{\the\@temptokena}% \else% \toks@\expandafter{#1}% \edef#1{\the\toks@\the\@temptokena}% \fi% \@temptokena{}\toks@\@temptokena% } \@onlypreamble\cref@addto % \end{macrocode} % \end{macro} % % % Passing a language option to \package{cleveref} defines the % cross-reference names and conjunctions as appropriate for that % lanauge. We can't make the definitions straight away, since they would % prevent the automatic definition of the other capitalisation variant % from working if the user chooses to change a default definition in the % preamble, so we postpone them until the beginning of the % document. However, if each language option were to simply to define any % formats that aren't already defined by the end of the preamble, the % \emph{first} language option would override all the % others. Unfortunately, the convention in \LaTeX{} and \package{babel} % is for the \emph{last} language option to take precedence. So we % instead used the \cmd{\crefname@preamble} command to save the % definitions in |\cref@\meta{type}@name@preamble| etc., and after all % the language options have been processed, use the contents of these to % set the default definitions for any undefined formats. % % For \package{babel} support, we add the appropriate redefinitions to % the\linebreak[4] |\extras|\meta{language} macro, which is called by % \package{babel}'s \cmd{\selectlanguage} at al.\ commands. The main % language (the last one listed in the options) is set up by an automatic % call to \cmd{\selectlanguage} at the beginning of the document, which % would clobber any redefinitions made by the user in the preamble. To % avoid this, we postpone adding the redefinitions to % |\extras|\meta{language} until the beginning of the document. Since % \package{cleveref} must always be loaded \emph{after} \package{babel}, % the redefinitions won't be added to |\extras|\meta{language} until % \emph{after} \package{babel} has already called \cmd{\selectlanguage} % for the main language. Thus the redefinitions will only be in effect % when \cmd{\selectlanguage} is called explicitly within the % document. (The definitions for the main language are taken care of by % the language options passed to \package{cleveref}, independently of % \package{babel}.) % % Note that we define both capitalisation variants explicitly throughout, % rather than relying on the automatic definition of the other variant, % in order to make the code produced by the poor man's |sed| script % slightly cleaner. % %
