For +%example, the \module{english} module provides +%\begin{definition}[\inpkg{datetime2-english}] +%\ics{DTMenglishmonthname}\marg{n} +%\end{definition} +%which is expandable. These types of commands are designed for use +%within language-dependent date styles. This ensures that the name +%matches the style. (One of the failings of \styfmt{datetime} was that +%the original date styles provided when the package was originally +%only intended for British dates produced weird hybrid styles when +%multilingual support was later added and styles such as \pkgoptfmt{long} +%were used with another language.) These types of commands provided +%by the \styfmt{datetime2} language modules are analogous to the +%\cs{monthname\meta{language}} commands provided by \styfmt{datetime}'s +%supporting language files (for example, +%\begin{definition}[\inpkg{datetime-defaults}] +%\oldcs{monthnameenglish}\oarg{n} +%\end{definition} +%in \styfmt{datetime-defaults} or +%\begin{definition}[\inpkg{dt-french.def}] +%\oldcs{monthnamefrench}\oarg{n} +%\end{definition} +%defined in \styfmt{dt-french.def}) except that the \styfmt{datetime} commands have +%an optional argument which means they're not expandable. +% +%If you load the \styfmt{datetime2-calc} package, +%either explicitly or through the \pkgopt{calc} or \pkgopt{showdow} +%\styfmt{datetime2} package options, then \sty{pgfcalendar} will also be +%loaded. In which case you can use +%\begin{definition}[\inpkg{pgfcalendar}] +%\ics{pgfcalendarmonthname}\marg{n} +%\end{definition} +%even if none of the \styfmt{datetime2} language modules have been +%loaded. This command requires the \sty{translator} package to +%provide multilingual support. See the \styfmt{pgf} manual for further +%details. +% +%Another possibility if you want the month name alone using the +%current language is to use the robust command +%\begin{definition}[\inpkg{datetime2-calc}] +%\ics{DTMmonthname}\marg{n} +%\end{definition} +%defined by \styfmt{datetime2-calc}. This is the closest match to +%\styfmt{datetime}'s \oldcs{monthname} command but note that the argument +%isn't optional. Remember that you can use \ics{month} for the current +%month number, which is the value of \meta{n} when omitted in +%\oldcs{monthname}. +% +%Old style (\styfmt{datetime}): +%\begin{verbatim} +%\documentclass{article} +% +%\usepackage[T1]{fontenc} +%\usepackage[utf8]{inputenc} +%\usepackage[french,english]{babel} +% +%\usepackage{datetime} +% +%\begin{document} +%\selectlanguage{french} +%\monthname +% +%\selectlanguage{english} +%\monthname +%\end{document} +%\end{verbatim} +%New style (\styfmt{datetime2} with the \module{french} and +%\module{english} modules): +%\begin{verbatim} +%\documentclass{article} +% +%\usepackage[T1]{fontenc} +%\usepackage[utf8]{inputenc} +%\usepackage[french,english]{babel} +% +%\usepackage[calc]{datetime2} +% +%\begin{document} +%\selectlanguage{french} +%\DTMmonthname{\month} +% +%\selectlanguage{english} +%\DTMmonthname{\month} +%\end{document} +%\end{verbatim} +% +%The abbreviated month name is given by +%\begin{definition}[\inpkg{datetime}] +%\oldcs{shortmonthname}\oarg{n} +%\end{definition} +%in +%\styfmt{datetime}.

If the current language +%doesn't provide a translation for the weekday names, then the +%English names are used. This command basically attempts to use +%\cs{dayofweeknameid\meta{lang}} (where \meta{lang} is given +%by \cs{languagename}) if it exists otherwise it uses +%\oldcs{dayofweeknameidenglish}. This language-sensitive macro is a fragile +%command that requires protection in moving arguments. +% +%As before, if the \styfmt{datetime2-calc} package is loaded, the +%\sty{pgfcalendar} package's commands are also available including +%\begin{definition}[\inpkg{pgfcalendar}] +%\ics{pgfcalendarweekdayname}\marg{dow} +%\end{definition} +%where the argument \meta{dow} is an integer from 0 (Monday) to 6 +%(Sunday).

This calculates the day of week +%index \meta{n}, an integer from 1 (Sunday) to 7 (Saturday), and then uses the +%result in the argument of \oldcs{dayofweeknameid}\marg{n}. The +%\cs{dayofweekname} command was provided by \styfmt{datetime} as a +%convenient shortcut for use in date styles. (Similarly for +%\oldcs{shortdayofweekname}.) With the \styfmt{datetime2} date styles, the +%day-of-week index is automatically available through the fourth +%argument of \ics{DTMdisplaydate} (and \ics{DTMDisplaydate}), so there +%is little use for an equivalent command. Additionally, if a date has +%already been saved with \styfmt{datetime2}, the weekday can be +%extracted from the saved data through \ics{DTMfetchdow}, which can be +%used in the argument of commands like \ics{DTMweekdayname} or +%\ics{DTMenglishweekdayname}. +% +%However, if a calculation is required for some reason, it can be +%obtained using the \sty{pgfcalendar} commands +%\ics{pgfcalendardatetojulian} and \ics{pgfcalendarjuliantoweekday}, +%which are described in the \styfmt{pgf} manual. +% +%The \styfmt{datetime} package provides the conditional +%\begin{definition}[\inpkg{datetime}] +%\oldcs{ifshowdow} +%\end{definition} +%which can be used to determine whether or not styles should display +%the weekday name (if supported). The \styfmt{datetime2} package has the +%analogous conditional +%\begin{definition}[\inpkg{datetime2}] +%\ics{ifDTMshowdow} +%\end{definition} +% +%The \styfmt{datetime} package provides the command +%\begin{definition}[\inpkg{datetime}] +%\oldcs{ordinaldate}\marg{n} +%\end{definition} +%as a date-type ordinal where the argument should be an integer from 1 +%to 31. For English, this just uses \sty{fmtcount}'s +%non-expandable \cs{ordinalnum} command. For Breton, Welsh and French +%a suffix is only added when the argument is 1. For all other +%languages, this command just displays the number. +% +%With \styfmt{datetime2}, the language modules may or may not provide a +%command to display the ordinal but most of them do. For example, the +%\module{english} module provides +%\begin{definition}[\inpkg{datetime2-english}] +%\ics{DTMenglishordinal}\marg{n} +%\end{definition} +%This displays the suffix using +%\begin{definition}[\inpkg{datetime2-english}] +%\ics{DTMenglishfmtordsuffix}\marg{suffix} +%\end{definition} +%The definition of this command is changed by the styles provided by +%the English regional modules. For example, the \style{en-US} style +%redefines \cs{DTMenglishfmtordsuffix} to ignore its argument. +%See the documentation for the \module{english} module for further +%details. +% +%The \module{french} module provides: +%\begin{definition}[\inpkg{datetime2-french}] +%\ics{DTMfrenchordinal}\marg{n} +%\end{definition} +%This displays \meta{n} and if \meta{n} is 1, a suffix is appended. +%See the \module{french} module documentation for further details. +% +%The \module{breton} module provides: +%\begin{definition}[\inpkg{datetime2-breton}] +%\ics{DTMbretonordinal}\marg{n} +%\end{definition} +%which similarly appends a suffix if \meta{n} is 1 but not for other +%values. In this case, the suffix for the first day is formatted using +%\begin{definition}[\inpkg{datetime2-breton}] +%\ics{DTMbretonfmtordinal}\marg{suffix} +%\end{definition} +%which is redefined by the \csopt{DTMlangsetup}{ord} option. +%See the \module{breton} module documentation for further details. +% +%The \module{welsh} module similarly provides: +%\begin{definition}[\inpkg{datetime2-welsh}] +%\ics{DTMwelshordinal}\marg{n} +%\end{definition} +%and +%\begin{definition}[\inpkg{datetime2-welsh}] +%\ics{DTMwelshfmtordinal}\marg{suffix} +%\end{definition} +%See the \module{welsh} module documentation for further details. +% +%Other modules may simply define \cs{DTM\meta{lang}ordinal} to just +%display its argument. For example, the \module{german} module +%provides +%\begin{definition}[\inpkg{datetime2-german}] +%\ics{DTMgermanordinal}\marg{n} +%\end{definition} +%which just displays \meta{n} (the day of month number). +% +%Alternatively, modules may define \cs{DTM\meta{lang}ordinal} to +%display its argument followed by a full stop (period). For example, +%the \module{norsk} module provides +%\begin{definition}[\inpkg{datetime2-norsk}] +%\ics{DTMnorskordinal}\marg{n} +%\end{definition} +%which displays \meta{n} followed by a full stop. +% +%As before, the date styles should explicitly use the ordinal macro +%that matches the style. However, if you have some need to display +%the day of month independent of any of the styles, you can use +%\begin{definition}[\inpkg{datetime2-calc}] +%\ics{DTMordinal}\marg{n} +%\end{definition} +%which is provided by \styfmt{datetime2-calc}.

(The default time style for +%\styfmt{datetime}.) Note that this style has no seconds. The format +%can be reproduced in \styfmt{datetime2} with the \style{default} +%style and the \pkgopt{showseconds} option set to \pkgoptfmt{false}: +%\begin{verbatim} +%\DTMsettimestyle{default} +%\DTMsetup{showseconds=false} +%\end{verbatim} +% +%\item[hhmmsstime] This is like the previous style but includes the +%seconds. This is the default time style for \styfmt{datetime2}: +%\begin{verbatim} +%\DTMsettimestyle{default} +%\end{verbatim} +% +%\item[ampmtime] This style produces the time in twelve hour format +%in the form 9:28am or 7:54pm. This style is available in some of the +%regional modules for \styfmt{datetime2}. For example, using the +%\style{en-GB} style in the \module{english} module: +%\begin{verbatim} +%\usepackage[en-GB]{datetime2} +%\end{verbatim} +%or +%\begin{verbatim} +%\usepackage[british]{babel} +%\usepackage{datetime2} +%\DTMsettimestyle{en-GB} +%\end{verbatim} +% +%\item[oclock] This style is designed for a full text English time +%format in the form: Twenty-Eight minutes past Ten in the afternoon. +%This style can be reproduced with the \style{en-FullText} style +%provided by the \sty{datetime2-en-fulltext} package: +%\begin{verbatim} +%\usepackage{datetime2-en-fulltext} +%\DTMsettimestyle{en-FullText} +%\end{verbatim} +% +%\end{description} +% +%\section{Defining a New Date Format} +% +%The \styfmt{datetime} package provides: +%\begin{definition}[\inpkg{datetime}] +%\oldcs{newdateformat}\marg{name}\marg{format} +%\end{definition} +%to define a new date style. Within \meta{format}, the placeholder +%commands \oldcs{THEDAY}, \oldcs{THEMONTH} and \oldcs{THEYEAR} are +%used to represent the relevant day, month and year values. There are +%also counter placeholders \texttt{DAY}, \texttt{MONTH} and +%\texttt{YEAR}, which may be used instead. +% +%A necessary consequence of allowing placeholder commands in +%\meta{format} means that these commands must be set as appropriate +%before the date can be formatted. This means that the formatted date +%can't be expanded and the date commands must be made robust to +%protect them in moving arguments. This is an inherent problem with the +%\styfmt{datetime} package that can't be fixed without breaking +%backwards compatibility and is one of the main reasons for +%introducing the replacement \styfmt{datetime2} package. +% +%The \styfmt{datetime2} package provides a better way of providing +%date styles, which are defined using: +%\begin{definition}[\inpkg{datetime2}] +%\ics{DTMnewdatestyle}\marg{name}\marg{definition} +%\end{definition} +%Instead of using placeholder commands, the date styles +%simply redefine the date formatting macros within \meta{definition}. +%There are two principle date formatting commands that the date style +%must define although styles may redefine additional helper commands +%if necessary. +% +%The two main date formatting commands are: +%\begin{definition}[\inpkg{datetime2}] +%\ics{DTMdisplaydate}\marg{YYYY}\marg{MM}\marg{DD}\marg{dow} +%\end{definition} +%for use where no case-changing is required and +%\begin{definition}[\inpkg{datetime2}] +%\ics{DTMDisplaydate}\marg{YYYY}\marg{MM}\marg{DD}\marg{dow} +%\end{definition} +%for use where the date must begin with an upper case letter, for +%example if the date occurs at the start of a sentence. For styles +%where the case-change is irrelevant (for example, numeric styles or +%styles that always start with an upper case letter), the +%\cs{DTMDisplaydate} command may simply be set to +%\cs{DTMdisplaydate}. +% +%The \styfmt{datetime} manual provides some examples of new date +%styles. The first is simply a numeric little-endian style with a hyphen +%separating each number: +%\begin{verbatim} +%\newdateformat{mydate}{\THEDAY-\THEMONTH-\THEYEAR} +%\end{verbatim} +% +%To convert this into a \styfmt{datetime2} format, the new style +%simply needs to redefine \cs{DTMdisplaydate} so that it has the +%following definition: +%\begin{verbatim} +%\renewcommand{\DTMdisplaydate}[4]{#3-#2-#1} +%\end{verbatim} +%Note that this command must always have four arguments, even if one +%or more of them are ignored. So here \cs{THEYEAR} is just the first +%argument \verb|#1|, \cs{THEMONTH} is the second argument \verb|#2| +%and \cs{THEDAY} is the third argument \verb|#3|. One other thing to note is +%that the arguments may be supplied with a leading zero. If you want +%to trim this off, you can use \TeX's \ics{number} primitive. For +%example: +%\begin{verbatim} +%\renewcommand{\DTMdisplaydate}[4]{\number#3-\number#2-\number#1 } +%\end{verbatim} +%This is the better method to allow for, say, registers used in any +%of the arguments. +% +%Therefore this new date style can be defined for \styfmt{datetime2} +%as follows: +%\begin{verbatim} +%\DTMnewdatestyle{mydate}{% +% \renewcommand{\DTMdisplaydate}[4]{\number##3-\number##2-\number##1 }% +% \renewcommand{\DTMDisplaydate}{\DTMdisplaydate}% +%} +%\end{verbatim} +%(Note the need to double the \verb|#| in the parameters, as is usual +%when redefining a command within another command in this manner.) +% +%For example, using \styfmt{datetime}: +%\begin{verbatim} +%\documentclass{article} +%\usepackage{datetime} +% +%\newdateformat{mydate}{\THEDAY-\THEMONTH-\THEYEAR} +%\mydate +% +%\begin{document} +%\today. +%\end{document} +%\end{verbatim} +%Now using \styfmt{datetime2}: +%\begin{verbatim} +%\documentclass{article} +%\usepackage{datetime2} +% +%\DTMnewdatestyle{mydate}{% +% \renewcommand{\DTMdisplaydate}[4]{\number##3-\number##2-\number##1 }% +% \renewcommand{\DTMDisplaydate}{\DTMdisplaydate}% +%} +%\DTMsetdatestyle{mydate} +% +%\begin{document} +%\today. +%\end{document} +%\end{verbatim} +% +%Another example provided in the \styfmt{datetime} manual ensures two +%digits for the month and day of month: +%\begin{verbatim} +%\newdateformat{dashdate}{\twodigit{\THEDAY}-\twodigit{\THEMONTH}-\THEYEAR} +%\end{verbatim} +% +%This is a minor modification to the previous example. The two digit +%number format can be obtained through \styfmt{datetime2}'s +%\ics{DTMtwodigits} command: +%\begin{verbatim} +%\DTMnewdatestyle{dashdate}{% +% \renewcommand{\DTMdisplaydate}[4]{% +% \DTMtwodigits{##3}-\DTMtwodigits{##2}-\number##1 }% +% \renewcommand{\DTMDisplaydate}{\DTMdisplaydate}% +%} +%\end{verbatim} +% +%A complete example follows for \styfmt{datetime}: +%\begin{verbatim} +%\documentclass{article} +%\usepackage{datetime} +% +%\newdateformat{dashdate}{\twodigit{\THEDAY}-\twodigit{\THEMONTH}-\THEYEAR} +%\dashdate +% +%\begin{document} +%\today. +%\end{document} +%\end{verbatim} +%And for \styfmt{datetime2}: +%\begin{verbatim} +%\documentclass{article} +%\usepackage{datetime2} +% +%\DTMnewdatestyle{dashdate}{% +% \renewcommand{\DTMdisplaydate}[4]{% +% \DTMtwodigits{##3}-\DTMtwodigits{##2}-\number##1 }% +% \renewcommand{\DTMDisplaydate}{\DTMdisplaydate}% +%} +%\DTMsetdatestyle{dashdate} +% +%\begin{document} +%\today. +%\end{document} +%\end{verbatim} +% +%You may have noticed that there's no equivalent of +%\styfmt{datetime}'s counter placeholders, but there's no real need +%for them and any attempt at implementing them would return to the +%original problem of preventing an expandable date format. \LaTeX\ +%counters all internally use \TeX\ count registers and counter +%formatting commands have to access those registers to determine the +%counter value. +% +%To illustrate this, the \styfmt{datetime} manual provides the +%example: +%\begin{verbatim} +%\newdateformat{usvardate}{\monthname[\THEMONTH] \ordinal{DAY}, \THEYEAR} +%\end{verbatim} +%This uses the \texttt{DAY} counter placeholder since \cs{ordinal} +%(provided by the \sty{fmtcount} package) requires a counter name as +%the argument. However, \cs{ordinal} internally uses \cs{ordinalnum} +%with the internal count register as the argument, so the format +%could just as easily be defined as: +%\begin{verbatim} +%\newdateformat{usvardate}{\monthname[\THEMONTH] \ordinalnum{\THEDAY}, \THEYEAR} +%\end{verbatim} +% +%So how can this style be reproduced with \styfmt{datetime2}? A +%na\"ive approach is: +%\begin{verbatim} +%\DTMnewdatestyle{usvardate}{% +% \renewcommand{\DTMdisplaydate}[4]{% +% \DTMmonthname{##2} \ordinalnum{##2}, \number##1 }% +% \renewcommand{\DTMDisplaydate}{\DTMdisplaydate}% +%} +%\end{verbatim} +%This requires both \styfmt{datetime2-calc} (for \ics{DTMmonthname}) +%and \sty{fmtcount} (for \cs{ordinalnum}). +% +%A complete example that uses it: +%\begin{verbatim} +%\documentclass{article} +% +%\usepackage{fmtcount} +%\usepackage[calc]{datetime2} +% +%\DTMnewdatestyle{usvardate}{% +% \renewcommand{\DTMdisplaydate}[4]{% +% \DTMmonthname{##2} \ordinalnum{##2}, \number##1 }% +% \renewcommand{\DTMDisplaydate}{\DTMdisplaydate}% +%} +%\DTMsetdatestyle{usvardate} +% +%\begin{document} +%\today. +%\end{document} +%\end{verbatim} +%This produces a warning from \cs{DTMmonthname} because +%\cs{DTMenglishmonthname} hasn't been defined, so it uses +%\cs{pgfcalendarmonthname} instead. The document displays the text: +%\begin{quote} +%January 1\textsuperscript{st}, 2016. +%\end{quote} +%This seems to produce the correct output, but let's see what happens +%if we make a minor modification to the example: +%\begin{verbatim} +%\documentclass{article} +% +%\usepackage[english,french]{babel} +%\usepackage{fmtcount} +%\usepackage[calc]{datetime2} +% +%\DTMnewdatestyle{usvardate}{% +% \renewcommand{\DTMdisplaydate}[4]{% +% \DTMmonthname{##2} \ordinalnum{##2}, \number##1 }% +% \renewcommand{\DTMDisplaydate}{\DTMdisplaydate}% +%} +%\DTMsetdatestyle{usvardate} +% +%\begin{document} +%\today. +%\end{document} +%\end{verbatim} +%This now produces: +%\begin{quote} +%janvier 1\textsuperscript{er}, 2016. +%\end{quote} +%which doesn't match the rationale of the style being a variation of +%the standard US date style nor does it match the little-endian +%syntax of French dates. +% +%Now let's make another minor change to the example: +%\begin{verbatim} +%\documentclass{article} +% +%\usepackage{fmtcount} +%\usepackage[calc]{datetime2} +% +%\DTMnewdatestyle{usvardate}{% +% \renewcommand{\DTMdisplaydate}[4]{% +% \DTMmonthname{##2} \ordinalnum{##2}, \number##1 }% +% \renewcommand{\DTMDisplaydate}{\DTMdisplaydate}% +%} +%\DTMsetdatestyle{usvardate} +% +%\begin{document} +%\section{\today: an example} +% +%\today. +%\end{document} +%\end{verbatim} +%This document can't compile properly and causes the error: +%\begin{verbatim} +%! Argument of \@sect has an extra }. +% +% \par +%\end{verbatim} +%This is because the style definition has made \cs{today} fragile +%because it uses an unprotected fragile command. This can be fixed by +%protecting \cs{ordinalnum} in the style definition. +% +%Let's make another modification: +%\begin{verbatim} +%\documentclass{article} +% +%\usepackage{fmtcount} +%\usepackage[calc]{datetime2} +% +%\DTMnewdatestyle{usvardate}{% +% \renewcommand{\DTMdisplaydate}[4]{% +% \DTMmonthname{##2} \protect\ordinalnum{##2}, \number##1 }% +% \renewcommand{\DTMDisplaydate}{\DTMdisplaydate}% +%} +%\DTMsetdatestyle{usvardate} +% +%\pagestyle{headings} +% +%\begin{document} +%\section{\today: an example} +% +%\today. +%\end{document} +%\end{verbatim} +%This compiles without error now that \cs{ordinalnum} has been +%protected, but the page header appears as: +%\begin{quote} +%\emph{1\quad January 1\textsuperscript{st}, 2016: AN EXAMPLE}\hfill 1 +%\end{quote} +%The date hasn't been rendered in upper case so the header doesn't +%look right. +% +%If \sty{hyperref} is added, another problem becomes evident: +%\begin{verbatim} +%\documentclass{article} +% +%\usepackage{fmtcount} +%\usepackage[calc]{datetime2} +%\usepackage[colorlinks]{hyperref} +% +%\DTMnewdatestyle{usvardate}{% +% \renewcommand{\DTMdisplaydate}[4]{% +% \DTMmonthname{##2} \protect\ordinalnum{##2}, \number##1 }% +% \renewcommand{\DTMDisplaydate}{\DTMdisplaydate}% +%} +%\DTMsetdatestyle{usvardate} +% +%\pagestyle{headings} +% +%\begin{document} +%\section{\today: an example} +% +%\today. +%\end{document} +%\end{verbatim} +%The PDF bookmarks for this document show the section title as: +%\begin{quote} +%01 , 2016: an example +%\end{quote} +% +%Both the header and the bookmark problem are caused by +%non-expandable elements of the date style. \emph{The same problems +%occur with \styfmt{datetime}}, and is one of the main reasons for +%developing a replacement package since these problems can't be fixed +%by \styfmt{datetime}.

Within \meta{format}, the placeholder +%commands \oldcs{THEHOUR}, \oldcs{THEMINUTE}, \oldcs{THESECOND}, +%\oldcs{THEHOURXII}, \oldcs{THETOHOUR}, \oldcs{THETOMINUTE} may be +%used. There are also corresponding placeholder counters: +%\texttt{HOUR}, \texttt{MINUTE}, \texttt{SECOND}, \texttt{HOURXII}, +%\texttt{TOHOUR} and \texttt{TOMINUTE}. +% +%This placeholder style of format for the time has the same problems +%as that for the date styles described in the previous section. +% +%Time styles are defined in \styfmt{datetime2} using: +%\begin{definition}[\inpkg{datetime2}] +%\ics{DTMnewtimestyle}\marg{name}\marg{definition} +%\end{definition} +% +%As with the date styles, the \styfmt{datetime2} package provides +%styles that redefine a formatting macro. In this case, the time +%(without the zone) is simply formatted with +%\begin{definition}[\inpkg{datetime2}] +%\ics{DTMdisplaytime}\marg{hh}\marg{mm}\marg{ss} +%\end{definition} +%so the \meta{definition} part of \cs{DTMnewtimestyle} needs to +%redefine this command. +% +%The placeholder commands \cs{THEHOUR}, \cs{THEMINUTE} +%and \cs{THESECOND} from \styfmt{datetime} can now be represented by +%the first, second and third arguments of \cs{DTMdisplaytime}.
