% \section{The French language}
%
% The file \file{\filename}\footnote{The file described in this
% section has version number \fileversion\ and was last revised on
% \filedate.}, defines all the language definition macros for the
% French language.
%
% Customisation for the French language is achieved following the
% book ``Lexique des règles typographiques en usage à
% l'Imprimerie Nationale'' troisième édition (1994),
% ISBN-2-11-081075-0.
%
% First version released: 1.1 (May 1996) as part of
% \babel-3.6beta. Version~2.0a was released in February 2007 and
% version~3.0a in February 2014.
%
% \frenchb{} has been improved using helpful suggestions from many
% people, mainly from Jacques André, Michel Bovani, Thierry Bouche,
% Vincent Jalby and Denis Bitouzé. Thanks to all of them!
%
% \LaTeX-2.09 is no longer supported.
% This new version (3.x) has been designed to be used only with
% \LaTeXe{} and Plain formats based on TeX, pdfTeX, LuaTeX or XeTeX
% engines.
%
% Changes between version 2.0 and \fileversion{} are listed in
% subsection~\ref{ssec-changes} p.~\pageref{ssec-changes}.
%
% An extensive documentation is available in French here:\\
% \url{http://daniel.flipo.free.fr/frenchb}
%
% \subsection{Basic interface}
%
% In a multilingual document, some typographic rules are language
% dependent, i.e.\ spaces before `high punctuation' (|:| |;| |!|
% |?|) in French, others modify the general layout (i.e.\ layout of
% lists, footnotes, indentation of first paragraphs of sections) and
% should apply to the whole document.
%
% \frenchb{} takes account of \babel's \emph{main language} defined
% as the \emph{last} option at \babel's loading. When French is
% not \babel's main language, \frenchb{} does not alter the general
% layout of the document (even in parts where French is the current
% language): the layout of lists, footnotes, indentation of first
% paragraphs of sections are not customised by \frenchb.
%
% When French is loaded as the last option of \babel, \frenchb{}
% makes the following changes to the global layout, \emph{both in
% French and in all other languages}\footnote{%
% For each item, hooks are provided to reset standard
% \LaTeX{} settings or to emulate the behavior of former versions
% of \frenchb{} (see command \fbsetup{},
% section~\ref{ssec-custom} p.~\pageref{ssec-custom}).}:
% \begin{enumerate}
% \item the first paragraph of each section is indented
% (\LaTeX{} only);
% \item the default items in itemize environment are set to `---'
% instead of `\textbullet', and all vertical spacing and glue
% is deleted; it is possible to change `---' to something else
% (`--' for instance) using \fbsetup{} (see
% section~\ref{ssec-custom} p.~\pageref{ssec-custom});
% \item vertical spacing in general \LaTeX{} lists is
% shortened;
% \item footnotes are displayed ``à la française''.
% \item the separator following the table or figure number in
% captions is printed as `~--~' instead of `:~'; for changing
% this see~\ref{sssec-captions} p.~\pageref{sssec-captions}.
% \end{enumerate}
%
% Regarding local typography, the command |\selectlanguage{french}|
% switches to the French language\footnote{%
% \cs{selectlanguage\{francais\}} and
% \cs{selectlanguage\{frenchb\}} are no longer supported.},
% with the following effects:
% \begin{enumerate}
% \item French hyphenation patterns are made active;
% \item `high punctuation' characters (|:| |;| |!| |?|)
% automatically add correct spacing in French; this is
% achieved using callbacks in Lua(La)TeX or `XeTeXinterchar'
% mechanism in Xe(La)TeX; with TeX'82 and pdf(La)TeX these
% four characters are made active in the whole document;
% \item |\today| prints the date in French;
% \item the caption names are translated into French
% (\LaTeX{} only). For customisation of caption names see
% section~\ref{sssec-captions} p.~\pageref{sssec-captions}.
% \item the space after |\dots| is removed in French.
% \end{enumerate}
%
% Some commands are provided by \frenchb{} to make typesetting
% easier:
% \begin{enumerate}
% \item French quotation marks can be entered using the commands
% |\og| and |\fg| which work in \LaTeXe and Plain\TeX,
% their appearance depending on what is available to draw
% them; even if you use \LaTeXe{} \emph{and} |T1|-encoding,
% you should refrain from entering them as
% |<<~French quotation~>>|: |\og| and |\fg| provide
% better horizontal spacing (controlled by |\FBguillspace|).
% If French quote characters are available on your keyboard,
% you can use them, to get proper spacing in \LaTeXe{} see
% option \fbo{og=«, fg=»} p.~\pageref{option-og-fg}.
%
% |\og| and |\fg| can be used outside French, they typeset
% then English quotes `` and ''.
%
% A new command |\frquote{}| has been added in version~3.1 to
% enter French quotations. |\frquote{|\textit{texte}|}| is
% equivalent to |\og| \textit{texte} |\fg{}| for short
% quotations. For quotations spreading over more than one
% paragraph, |\frquote| will add at the beginning of every
% paragraph of the quotation either an opening French
% guillemet («), or a closing one (») depending on option
% \fbo{EveryParGuill=open} or \fbo{=close}, see
% p.~\pageref{everyparguill}.\label{frquote}
%
% |\frquote| is recommended to enter embedded quotations ``à la
% française'', several variants are provided through options:
% \begin{itemize}
% \item with LuaTeX based engines, every line of the inner
% quotation will start with a French guillemet (« or »)
% depending on option \fbo{EveryLineGuill=open} (default) or
% \fbo{=close} unless you explicitly set
% \fbo{EveryLineGuill=none}, then |\frquote{}| will behave
% as with non-LuaTeX engines;
% \item with all other engines, the inner quotation is
% surrounded by double quotes (``\textit{texte}'') unless
% option \fbo{InnerGuillSingle=true}, then a) the inner
% quotation is printed as
% \guilsinglleft\FBguillspace\textit{texte}\FBguillspace
% \guilsinglright{} and b) if the inner quotation
% spreads over more than one paragraph, every paragraph
% included in the inner quotation starts with
% a \guilsinglleft{} or a \guilsinglright, depending on
% option \fbo{EveryParGuill=open} or \fbo{close}.
% \end{itemize}
% A starred variant |\frquote*| is meant for inner quotations
% which end together with the outer one: using |\frquote*| for
% the inner quotation will print only one closing quote
% character (the outer one) as recommended by the French
% `Imprimerie Nationale'.
%
% \item A command |\up| is provided to typeset superscripts like
% |M\up{me}| (abbreviation for ``Madame''), |1\up{er}| (for
% ``premier''). Other commands are also provided for
% ordinals: |\ier|, |\iere|, |\iers|, |\ieres|, |\ieme|,
% |\iemes| (|3\iemes| prints 3\textsuperscript{es}).
% All these commands take advantage of real superscript
% letters when they are available in the current font.
%
% \item Family names should be typeset in small capitals and never
% be hyphenated, the macro |\bsc| (boxed small caps) does
% this, e.g., |L.~\bsc{Lamport}| will print the same as
% |L.~\mbox{\textsc{Lamport}}|. Note that composed names
% (such as Dupont-Durant) may now be hyphenated on explicit
% hyphens, this differs from \frenchb~v.~1.x.
%
% \item Commands |\primo|, |\secundo|, |\tertio| and |\quarto|
% print 1\textsuperscript{o}, 2\textsuperscript{o},
% 3\textsuperscript{o}, 4\textsuperscript{o}.
% |\FrenchEnumerate{6}| prints 6\textsuperscript{o}.
% \item Abbreviations for ``Numéro(s)'' and ``numéro(s)''
% (N\textsuperscript{o} N\textsuperscript{os}
% n\textsuperscript{o} and n\textsuperscript{os}~)
% are obtained via the commands |\No|, |\Nos|, |\no|, |\nos|.
%
% \item Two commands are provided to typeset the symbol for
% ``degré'': |\degre| prints the raw character and
% |\degres| should be used to typeset temperatures (e.g.,
% ``|20~\degres C|'' with an unbreakable space), or for
% alcohols'' strengths (e.g., ``|45\degres|'' with \emph{no}
% space in French).
%
% \item In math mode the comma has to be surrounded with
% braces to avoid a spurious space being inserted after it,
% in decimal numbers for instance (see the \TeX{}book p.~134).
% The command |\DecimalMathComma| makes the comma be an
% ordinary character \emph{in French only} (no space added);
% as a counterpart, if |\DecimalMathComma| is active, an
% explicit space has to be added in lists and intervals:
% |$[0,\ 1]$|, |$(x,\ y)$|. |\StandardMathComma| switches
% back to the standard behaviour of the comma.
%
% \item A command |\nombre| was provided in 1.x versions to easily
% format numbers in slices of three digits separated either
% by a comma in English or with a space in French; |\nombre|
% is now mapped to |\numprint| from \file{numprint.sty}, see
% \file{numprint.pdf} for more information.
%
% \item \frenchb{} has been designed to take advantage of the
% \pkg{xspace} package if present: adding
% |\usepackage{xspace}| in the preamble will force macros like
% |\fg|, |\ier|, |\ieme|, |\dots|, \dots, to respect the
% spaces you type after them, for instance typing
% `|1\ier juin|' will print `1\textsuperscript{er} juin'
% (no need for a forced space after |1\ier|).
% \end{enumerate}
%
% \subsection{Customisation}
% \label{ssec-custom}
%
% Customisation of \frenchb{} relies on command \fbsetup{},
% options are entered using the \file{keyval} syntax.
% The command \fbsetup{} is to appear in the preamble only
% (after loading \babel).
%
% \subsubsection[\textbackslash frenchbsetup{}]
% {\fbsetup{options}}
% \label{sssec-frenchbsetup}
%
% \vspace{.5\baselineskip}
% \fbsetup{ShowOptions} prints all available options to
% the \file{.log} file, it is just meant as a remainder of the
% list of offered options. As usual with \file{keyval} syntax,
% boolean options (as \fbo{ShowOptions}) can be entered as
% \fbo{ShowOptions=true} or just \fbo{ShowOptions}, the
% \fbo{=true} part can be omitted.
%
% \vspace{.5\baselineskip}
% The other options are listed below. Their default value is
% shown between braces, sometimes followed be a `\texttt{*}'.
% The `\texttt{*}' means that the default shown applies when
% \frenchb{} is loaded as the \emph{last} option of \babel{}
% ---\babel's \emph{main language}---, and is toggled otherwise.
% \begin{description}
% \item [StandardLayout=true (false*)] forces \frenchb{} not to
% interfere with the layout: no action on any kind of lists,
% first paragraphs of sections are not indented (as in English),
% no action on footnotes. This option can be used to avoid
% conflicts with classes or packages which customise lists or
% footnotes.
% \item [GlobalLayoutFrench=false (true*)] should no longer be
% used; it was intended to emulate, when French is the main
% language, what prior versions of \frenchb{} (pre-2.2) did:
% lists, and first paragraphs of sections would be displayed
% the standard way in other languages than French, and ``à la
% française'' in French. Note that the layout of footnotes is
% language independent anyway (see below \fbo{FrenchFootnotes}
% and \fbo{AutoSpaceFootnotes}).
% \item [ReduceListSpacing=false (true*)]; \frenchb{} reduces the
% values of the vertical spaces used in the \emph{all} list
% environments in French (this includes itemize, enumerate,
% description, but also abstract, quote, quotation and verse and
% possibly others). Setting this option to \fbo{false}
% reverts to the standard settings of the |list| environment.
% \item [ListOldLayout=true (false)]; starting with version~2.6a,
% the layout of lists has changed regarding leftmargins' sizes
% and default itemize label (`---' instead of `--' up to~2.5k).
% This option, provided for backward compatibility, displays
% lists as they were up to version~2.5k.
% \item [CompactItemize=false (true*)]; should no longer be used
% (kept only for backward compatibility), it is replaced by the
% next two options.
% \item [StandardItemizeEnv=true (false*)]; \frenchb{} redefines
% the |itemize| environment to suppress any vertical space
% between items of |itemize| lists in French and customises
% left margins. Setting this option to \fbo{false} reverts to
% the standard definition of |itemize|.
% \item [StandardEnumerateEnv=true (false*)]; starting with
% version~2.6 \frenchb{} redefines the |enumerate| and
% |description| environments to make left margins match those of
% the French version of |itemize| lists. Setting this option to
% \fbo{false} reverts to the standard definition of |enumerate|
% and |description|.
% \item [StandardItemLabels=true (false*)] when set to \fbo{true}
% this option prevents \frenchb{} from changing the labels in
% |itemize| lists in French.
% \item [ItemLabels=\cs{textbullet}, \cs{textendash},
% \cs{ding\{43\}},...(\cs{textemdash}*)];\\
% when \fbo{StandardItemLabels=false} (the default), this option
% enables to choose the label used in French |itemize| lists for
% all levels. The next four options do the same but each one for
% a specific level only. Note that the example |\ding{43}|
% requires |\usepackage{pifont}|.
% \item [ItemLabeli=\cs{textbullet}, \cs{textendash},
% \cs{ding\{43\}},...(\cs{textemdash}*)]
% \item [ItemLabelii=\cs{textbullet}, \cs{textendash},
% \cs{ding\{43\}},...(\cs{textemdash}*)]
% \item [ItemLabeliii=\cs{textbullet}, \cs{textendash},
% \cs{ding\{43\}},..(\cs{textemdash}*)]
% \item [ItemLabeliv=\cs{textbullet}, \cs{textendash},
% \cs{ding\{43\}},...(\cs{textemdash}*)]
% \item [StandardLists=true (false*)] forbids \frenchb{} to
% customise any kind of list. Try the option \fbo{StandardLists}
% in case of conflicts with classes or packages that customise
% lists too. This option is just a shorthand setting all four
% options \fbo{ReduceListSpacing=false},
% \fbo{StandardItemizeEnv=true}, \fbo{StandardEnumerateEnv=true}
% and \fbo{StandardItemLabels=true}.
% \item [IndentFirst=false (true*)]; set this option to \fbo{false}
% if you do not want \frenchb{} to force indentation of the
% first paragraph of sections. When French is the main language,
% this options applies to all languages.
% \item [FrenchFootnotes=false (true*)] reverts to the standard
% layout of footnotes. By default \frenchb{} typesets leading
% numbers as `1.\hspace{.5em}' instead of `$\hbox{}^1$', but
% has no effect on footnotes numbered with symbols (as in the
% |\thanks| command). Two commands |\StandardFootnotes|
% and |\FrenchFootnotes| are available to change the layout of
% footnotes locally; |\StandardFootnotes| can help when some
% footnotes are numbered with letters (inside minipages for
% instance).
% \item [AutoSpaceFootnotes=false (true*)]; by default \frenchb{}
% adds a thin space in the running text before the number or
% symbol calling the footnote. Making this option \fbo{false}
% reverts to the standard setting (no space added).
% \item [FrenchSuperscripts=false (true)]; then
% |\up=\textsuperscript| (option added in version 2.1).
% Should only be made \fbo{false} to recompile older documents.
% By default |\up| now relies on |\fup| designed to produce
% better looking superscripts.
% \item [AutoSpacePunctuation=false (true)]; in French, the user
% \emph{should} input a space before the four characters `|:;!?|'
% but as many people forget about it (even among native French
% writers!), the default behaviour of \frenchb{} is to
% automatically typeset nobreakspaces the width of which is
% either |\FBthinspace| (defauts to |\thinspace|) before `|;|'
% `|!|' `|?|' or |\FBcolonspace| (defauts to |\space|) before
% `|:|'; the defaults follow the French `Imprimerie Nationale's
% recommendations. This is convenient in most cases but can lead
% to addition of spurious spaces in URLs, in MS-DOS paths or in
% timetables (10:55), except if they are typed in |\texttt| or
% verbatim mode. When the current font is a monospaced
% (typewriter) font, \fbo{AutoSpacePunctuation} is locally
% switched to \fbo{false}, no spurious space is added in that
% case, so the default behaviour of of \frenchb{} in that area
% should be fine in most circumstances.
%
% Choosing \fbo{AutoSpacePunctuation=false} will ensure that
% a proper space will be added before `|:;!?|' \emph{if and only
% if} a (normal) space has been typed in. Those who are unsure
% about their typing in this area should stick to the default
% option and use the provided |\NoAutoSpacing| command
% inside a group in case an unwanted space is added by \frenchb{}
% (i.e.\ |{\NoAutoSpacing 10:55}|).
% \item [ThinColonSpace=true (false)] changes the inter-word
% unbreakable space added before the colon `:' to a thin space,
% so that the same amount of space is added before any of the
% four `high punctuation' characters. The default setting is
% supported by the French `Imprimerie Nationale'.
% \item [LowercaseSuperscripts=false (true)]; by default \frenchb{}
% inhibits the uppercasing of superscripts (for instance when
% they are moved to page headers). Making this option
% \fbo{false} will disable this behaviour (not recommended).
% \item [PartNameFull=false (true)]; when true, \frenchb{} numbers
% the title of |\part{}| commands as ``Première partie'',
% ``Deuxième partie'' and so on. With some classes which
% change the |\part{}| command (AMS classes do so), you could
% get ``Première partie~1'', ``Deuxième partie~2'' in the toc;
% when this occurs, this option should be set to
% \fbo{false}, part titles will then be printed as ``Partie I'',
% ``Partie II''.
% \item [CustomiseFigTabcaptions=false (true*)]; when \fbo{false}
% the default separator (colon) is used instead of
% |\CaptionSeparator|. Anyway, \frenchb{} makes sure that the
% colon will be typeset with proper preceeding space in French.
% \item [OldFigTabcaptions=true (false)] is to be used when
% figures' and tables' captions must be typeset as with pre~3.0
% versions of \frenchb{} (with |\CaptionSeparator| in French and
% colon otherwise). Intended for standard \LaTeX{} classes only.
% \item [SuppressWarning=true (false)]; can be turned to \fbo{true}
% if you are bored with \frenchb's warnings.
% \item [INGuillSpace=true (false)] resets the dimensions of spaces
% after opening French quotes and before closing French quotes to
% the French `Imprimerie Nationale' standards (inter-word space).
% \frenchb's default setting produces slightly narrower spaces
% with lesser stretchability.
% \item [EveryParGuill=open, close, none (open)]; sets whether
% an opening quote (\texttt{«}) or a closing one (\texttt{»}) or
% nothing should be printed by |\frquote{}| at the beginning of
% every parapraph in case of a level 1 (outer) quotation
% spreading over more than one parapraph. This option is also
% considered for level 2 (inner) quotations to decide between
% \texttt{\guilsinglleft} and \texttt{\guilsinglright} when
% \fbo{InnerGuillSingle=true} (see below). \label{everyparguill}
% \item [EveryLineGuill=open, close, none (open in LuaTeX, none
% otherwise)]; with engines other than LuaTeX this
% option is set to \fbo{none} which means that nothing will be
% printed at the beginning of every line of inner quotations,
% trying to set this option will issue a warning in the
% \file{.log} file.
%
% With LuaTeX based engines, this option is set to \fbo{open} by
% default, it ensures that a \guillemotleft{} followed by proper
% kern will be repeated at the beginning of every line in case an
% embedded (inner) quotation spreads over more than one line
% (provided that both outer and inner quotations are entered with
% |\frquote{}|). Set this option to \fbo{close} if you want
% a \guillemotright{} instead of a \guillemotleft.
% \item [InnerGuillSingle=true (false)];
% if \fbo{InnerGuillSingle=false} (default), inner quotations
% entered with |\frquote{}| start with~\texttt{``} and end
% with~\texttt{''}.
% If \fbo{InnerGuillSingle=true}, \texttt{\guilsinglleft} and
% \texttt{\guilsinglright} are used instead of British double
% quotes. Please note that this option only makes
% sense when \fbo{EveryLineGuill=none}.
% \item [og=\guillemotleft, fg=\guillemotright];
% when guillemets characters are available on the keyboard
% (through a compose key for instance), it is nice to use them
% instead of typing |\og| and |\fg|. This option tells
% \frenchb{} which characters are opening and closing French
% guillemets (they depend on the input encoding), then you can
% type either \label{option-og-fg}
% \texttt{\guillemotleft{} guillemets \guillemotright} or
% \texttt{\guillemotleft{}guillemets\guillemotright} (with or
% without spaces) to get properly typeset French quotes.
% This option works with LuaLaTeX and XeLaTeX; with pdfLaTeX it
% requires \file{inputenc} to be loaded with a proper encoding:
% 8-bits encoding (latin1, latin9, ansinew, applemac,\dots) or
% multi-byte encoding (utf8, utf8x).
% \end{description}
%
% \textbf{Options' order} -- Please remember that options are read
% in the order they appear in the \fbsetup{} command.
% Someone wishing that \frenchb{} leaves the layout of lists
% and footnotes untouched but caring for indentation of first
% paragraph of sections should choose\\
% \fbsetup{StandardLayout,IndentFirst} to get the expected
% layout. The reverse order
% \fbsetup{IndentFirst,StandardLayout} would lead to option
% \fbo{IndentFirst} being overwritten by \fbo{StandardLayout}.
%
% \subsubsection{Captions}
% \label{sssec-captions}
%
% Caption names can be customised in French using the simplified
% syntax introduced by \babel~3.9, for instance:
% |\def\frenchproofname{Preuve}|.
% The older syntax |\addto\captionsfrench{\def\proofname{Preuve}}|
% still works. Keep in mind that \emph{only} |french| can be used to
% redefine captions, even if \babel{}'s option was entered as
% |francais| or |frenchb|.
%
% For \emph{all} languages, when French is the main language,
% \frenchb{} changes the separator (colon) used in figures'
% and tables' captions to |\CaptionSeparator| which defaults to
% `~--~' and can be redefined in the preamble with\\
% |\renewcommand*{\CaptionSeparator}{...}|.
%
% When French is not the main language, the colon is preserved for
% all languages but \frenchb{} makes sure that a proper space is
% typeset before it.
%
% Two new options are provided: if \fbo{CustomiseFigTabCaptions} is
% set to \fbo{false} the colon will be used as separator in all
% languages, with a proper space before the colon in French.
% The second option \fbo{OldFigTabCaptions} can be set to \fbo{true}
% to print figures' and tables' captions as they were with versions
% pre~3.0 of \frenchb{} (using |\CaptionSeparator| in French and
% colon in other languages); this option only makes sense with the
% standard \LaTeX{} classes \cls{article}, \cls{report} and
% \cls{book}.
%
% \subsection{Hyphenation checks}
% \label{ssec-hyphen}
%
% Once you have built your format, a good precaution would be to
% perform some basic tests about hyphenation in French.
% For \LaTeXe{} I suggest this:
% \begin{itemize}
% \item run |pdfLaTeX| on the following file, with the encoding

% \subsection{Changes}
% \label{ssec-changes}
%
% \subsubsection*{What's new in version 3.1?}
%
% New command |\frquote{}| meant to enter French quotations,
% especially long ones (spreading over several paragraphs) and/or
% embedded ones. see p.~\pageref{frquote} for details.
%
% \subsubsection*{What's new in version 3.0?}
%
% Many deep changes lead me to step \frenchb's version number
% to~3.0a:
% \begin{itemize}
% \item \babel{}~3.9 is required now to process
% \file{frenchb.ldf}, this change allows for cleaner definitions
% of dates and captions for the Unicode engines LuaTeX and
% XeTeX and also provides a simpler syntax for end-users, see
% section~\ref{sssec-captions} p.\pageref{sssec-captions}.
% \item \fbsetup{} options management has been completely
% reworked; two new options added.
% \item Canadian French didn't work as a normal \babel's dialect,
% it should now; btw. the French language should now be loaded
% as \Lopt{french}, \emph{not as} \Lopt{frenchb} or
% \Lopt{francais} and preferably as a \emph{global} option of
% |\documentclass|. Some tolerance still exists in v3.0, but
% do not rely on it.
% \item \frenchb{} no longer loads \file{frenchb.cfg}:
% customisation should definitely be done using \fbsetup{}
% options.
% \item Description lists labels are now indented; set
% |\listendentFB=0pt| to get the former layout.
% \item The last but not least change affects the (recent)
% LuaTeX-based engines, (this means version 0.76 as included in
% TL2013 and up): active characters are no longer used in French
% for `high punctuation'. Functionalities and user interface
% are unchanged.
%
% Many thanks to Paul Isambert who provided the basis for the
% lua code (see his presentation at GUT'2010) and kindly
% reviewed my first drafts suggesting significant improvements.
%
% Please note that this code, still experimental, is likely to
% change until LuaTeX itself has reached version~1.0.
% \end{itemize}
%
% Starting with version~3.0c, \frenchb{} no longer customises
% lists with the \cls{beamer} class and offers a new option
% (\fbo{INGuillSpace}) to follow French `Imprimerie Nationale'
% recommendations regarding quotes' spacing.
%
% \subsubsection*{What's new in version 2.6?}
%
% The way \frenchb{} handles list environments has been completely
% redesigned in version~2.6 due to a long standing bug affecting
% enumerate lists inside itemize lists. Horizontal indentation of
% itemize, enumerate and description lists differs now from
% previous versions, an option for backward compatibility is
% provided: \fbsetup{ListOldLayout}.
%
% \frenchb{} is now compatible with the \pkg{paralist} package.
%
% Regarding the layout of figures' and tables' captions, version
% 2.6c is now fully compatible with AMS and koma-script classes
% and with \file{caption} and \pkg{floatrow} packages.
% Starting with version 2.6c, the \file{frenchb.cfg} file is no
% longer generated from \file{frenchb.dtx}, but it is still loaded
% (if found) for backward compatibility.
%
% \subsubsection*{What's new in version 2.5?}
%
% The main change is that active characters are no longer used
% in French with (recent) XeTeX-based engines (they still are
% with TeX-based engines). All the functionalities (automatic
% insertion of missing spaces before |:;!?| or bare replacement
% of typed spaces with suitable unbreabable ones, tuning of the
% spaces width) remain available and the user interface is
% unchanged. The use of active characters is replaced by the
% |\XeTeXinterchartoks| mechanism (adapted from the
% \pkg{polyglossia} package).
%
% A new command |\NoAutoSpacing| has been added. It should be used
% \emph{inside a group} instead of |\shorthandoff{;:!?}| whenever
% active characters or automatic spacing of French punctuation or
% quote characters conflict with other packages; it is designed to
% work with TeX-, LuaTeX- and XeTeX-based engines.
%
% Bug corrections: |\frenchspacing| and |\nonfrenchspacing| are no
% longer messed up by \file{frenchb.ldf}.
%
% \subsubsection*{What's new in version 2.4?}
%
% A new option \fbo{SuppressWarning} has been added (desactivated
% by default) to suppress warnings if |\@makecaption| has been
% redefined or if the \pkg{bigfoot} package is in use.
%
% French hyphenation patterns are now coded in Unicode, see file
% \file{hyph-fr.tex}. Extra code has been added to deal with
% hyphenation of the French ``apostrophe'' with XeTeX and LuaTeX
% engines.
%
% Better compatibility with the \pkg{enumitem} package.
%
% When typewriter fonts are in use (hence in verbatim mode) no
% space is added after `\guillemotleft' and before
% `\guillemotright' when they are entered as characters
% (see \fbsetup{}).
%
% \subsubsection*{What's new in version 2.3?}
%
% Starting with version~2.3a, \frenchb{} no longer inserts spaces
% automatically before `|:;!?|' when a typewriter font is in use;
% this was suggested by Yannis Haralambous to prevent
% spurious spaces in computer source code or expressions like
% \texttt{C\string:/foo}, \texttt{http\string://foo.bar},
% etc. An option (\fbo{OriginalTypewriter}) is provided to get
% back to the former behaviour of \frenchb{}.
%
% Another probably invisible change: lowercase conversion in
% |\up{}| is now achieved by the \LaTeX{} command |\MakeLowercase|
% instead of \TeX's |\lowercase| command. This prevents error
% messages when diacritics are used inside |\up{}| (diacritics
% should \emph{never} be used in superscripts though!).
%
% \subsubsection*{What's new in version 2.2?}
%
% Starting with version~2.2a, \frenchb{} alters the layout of
% lists, footnotes, and the indentation of first paragraphs of
% sections) \emph{only if} French is the ``main language''
% (i.e. \babel's last language option). The layout is global for
% the whole document: lists, etc.\ look the same in French and in
% other languages, everything is typeset ``à la française''
% if French is the ``main language'', otherwise \frenchb{} doesn't
% change anything regarding lists, footnotes, and indentation of
% paragraphs.
%
% \subsubsection*{What's new in version 2.1?}
%
% A new command |\fup| is provided to typeset better looking
% superscripts; it was designed using ideas from Jacques André,
% Thierry Bouche and René Fritz, thanks to all of them!
% Former command |\up| is now defined as |\fup|, an option
% \fbo{FrenchSuperscripts=false} is provided for
% backward compatibility.
%
% \subsubsection*{What's new in version 2.0?}
%
% Here is the list of all changes:
% \begin{itemize}
% \item Support for \LaTeX-2.09 and for \LaTeXe{} in compatibility
% mode has been dropped. This version is meant for \LaTeXe{} and
% Plain based formats (like \file{bplain}). \LaTeXe{} formats
% based on ml\TeX{} are no longer supported either (plenty of
% good 8-bits fonts are available now, so T1 encoding should
% be preferred for typesetting in French). A warning is issued
% when OT1 encoding is in use at the |\begin{document}|.
% \item Customisation should now be handled only by command
% \fbsetup{}, \file{frenchb.cfg} (kept for compatibility)
% should no longer be used. See section~\ref{ssec-custom} for
% the list of available options.
% \item Captions in figures and tables have changed in French: former
% abbreviations ``Fig.'' and ``Tab.'' have been replaced by full
% names ``Figure'' and ``Table''. If this leads to formatting
% problems in captions, you can add the following two commands to
% your preamble (after loading \babel) to get the former captions\\
% |\addto\captionsfrench{\def\figurename{{\scshape Fig.}}}|\\
% |\addto\captionsfrench{\def\tablename{{\scshape Tab.}}}|.
% \item The |\nombre| command is now provided by the \pkg{numprint}
% package which has to be loaded \emph{after} \babel{} with the
% option |autolanguage| if number formatting should depend on the
% current language.
% \item The |\bsc| command no longer uses an |\hbox| to stop
% hyphenation of names but a |\kern0pt| instead. This change
% enables \file{microtype} to fine tune the length of the
% argument of |\bsc|; as a side-effect, compound names like
% Dupont-Durand can now be hyphenated on explicit hyphens.
% You can get back to the former behaviour of |\bsc| by adding\\
% |\renewcommand*{\bsc}[1]{\leavevmode\hbox{\scshape #1}}|\\
% to the preamble of your document.
% \item Footnotes are now displayed ``à la française'' for the
% whole document, except with an explicit\\
% \fbsetup{AutoSpaceFootnotes=false,FrenchFootnotes=false}.\\
% Add this command if you want standard footnotes. It is still
% possible to revert locally to the standard layout of footnotes
% by adding |\StandardFootnotes| (inside a |minipage| environment
% for instance).

%
% As long as no better solution is available, the `high

% \subsubsection{Punctuation with XeTeX}
% \label{sssec-punct-xetex}
%
% If |\XeTeXinterchartokenstate| is available, we use the
% ``inter char'' mechanism to provide correct spacing in French
% before the four characters |;| |!| |?| and |:|. The basis of the
% following code was borrowed from the \pkg{polyglossia} package,
% see \file{gloss-french.ldf}. We use the same mechanism for French
% quotes (\texttt{\guillemotleft} and \texttt{\guillemotright}),
% when automatic spacing for quotes is required by options
% \fbo{og=} and \fbo{fg=} in \fbsetup{} (see
% section~\ref{ssec-keyval}).
%
% For every character used in French text-mode (except spaces),
% |\XeTeXcharclass| value must be 0.
% |\XeTeXcharclass| value for spaces is assumed to be 255.
% Otherwise, the spacing before the `high punctuation' characters
% and inside quotes might not be correct.
%
% We switch |\XeTeXinterchartokenstate| to 1 and change the
% |\XeTeXcharclass| values of |;| |!| |?| |:| |(| |]|
% \texttt{\guillemotleft} and \texttt{\guillemotright} when
% entering French. Special care is taken to restore them to their
% inital values when leaving French.

% \subsubsection{Punctuation with standard (pdf)TeX}
% \label{sssec-punct-tex}
%
% In standard (pdf)TeX we need to make the four characters |;| |!| |?|
% and |:| `active' and provide their definitions.
% \begin{macrocode}
\ifFB@active@punct
\initiate@active@char{:}%
\initiate@active@char{;}%
\initiate@active@char{!}%
\initiate@active@char{?}%
% \end{macrocode}
% We first tune the amount of space before \texttt{;}
% \texttt{!} \texttt{?} and \texttt{:}. This should only happen
% in horizontal mode, hence the test |\ifhmode|.
%
% In horizontal mode, if a space has been typed before `;' we
% remove it and put an unbreakable |\FBthinspace| instead. If no
% space has been typed, we add |\FDP@thinspace| which will be
% defined, up to the user's wishes, as |\FBthinspace|, or as
% |\@empty|.
% \begin{macrocode}
\declare@shorthand{french}{;}{%
\ifhmode
\ifdim\lastskip>\z@
\unskip\penalty\@M\FBthinspace
\else
\FDP@thinspace
\fi
\fi
% \end{macrocode}
% Now we can insert a |;| character.
% \begin{macrocode}
\string;}
% \end{macrocode}
% The next three definitions are very similar.
% \begin{macrocode}
\declare@shorthand{french}{!}{%

\ifdim\lastskip>\z@

\fi

% \end{macrocode}
% When the active characters appear in an environment where their
% French behaviour is not wanted they should give an `expected'
% result. Therefore we define shorthands at system level as well.
% \begin{macrocode}

% The only packages I currently know to take advantage of real
% superscripts are a) \pkg{realscripts} used in conjunction with
% XeLaTeX or LuaLaTeX and OpenType fonts having the font feature
% 'VerticalPosition=Superior' and b) \pkg{fourier}
% (from version 1.6) when Expert Utopia fonts are available.
%
% |\FB@up| checks whether the current font is a Type1 `Expert'
% (or `Pro') font with real superscripts or not (the code works
% currently only with \file{fourier-1.6} but could work with any
% Expert Type1 font with built-in superscripts, see below), and
% decides to use real or fake superscripts.
% It works as follows: the content of |\f@family| (family name of
% the current font) is split by |\FB@split| into two pieces, the
% first three characters (`|fut|' for Fourier, `|ppl|' for Adobe's
% Palatino, \dots) stored in |\FB@firstthree| and the rest stored
% in |\FB@suffix| which is expected to be `|x|' or `|j|' for expert
% fonts.

% With LuaLaTeX and XeLaTeX, this glitch doesn't occur, you get

% provides the following workaround.
%
% The standard definition of |\@makecaption| (e.g., the one provided
% in article.cls, report.cls, book.cls which is frozen for \LaTeXe{}

% `AtBeginDocument' we compare it to its current definition (some
% classes like \cls{memoir}, koma-script classes, AMS classes,
% ua-thesis.cls\dots change it).
% If they are identical, \frenchb{} just adds a hook called
% |\FBCaption@Separator| to |\@makecaption|; |\FBCaption@Separator|
% defaults to `: ' as in the standard |\@makecaption| and will be

% All setup options are handled by command \fbsetup{} using the

%
% Option processing can occur either in \fbsetup{}, but \emph{only

% any option affecting |\extrasfrench{}| \emph{must} be processed by
% \fbsetup{}: when French is the main language, |\extrasfrench{}| is
% executed by \babel{} when it switches the main language and this
% occurs \emph{before} reading the stuff postponed by \frenchb{}
% `AtBeginDocument'. Reexecuting |\extrasfrench{}| is a possibility
% which was used up to v2.6h, it has been dropped in v3.0a because
% of its side-effects (f.i. |\babel@save| and |\babel@savevariable|
% no longer work).
%
% \begin{macro}{\frenchbsetup}

% Vertical spacing in lists should be shorter in French texts than

% Note that the easy way, just changing values of vertical spacing

% defaults on exit would not work; so we define the command

% to |\listFB| reduces vertical spacing in \emph{all} environments
% built on |\list|: |itemize|, |enumerate|, |description|, but also
% |abstract|, |quotation|, |quote| and |verse|\dots{}
%
% The amount of vertical space before and after a list is given by
% |\topsep| + |\parskip| (+ |\partopsep| if the list starts a new
% paragraph). IMHO, |\parskip| should be added \emph{only} when
% the list starts a new paragraph, so I subtract |\parskip| from
% |\topsep| and add it back to |\partopsep|; this will normally

% the baseline (instead of superscripts) and followed by a dot
% and an half quad space. Whenever symbols are used to number
% footnotes (as in |\thanks| for instance), we switch back to the
% standard layout (the French layout of footnotes is meant for
% footnotes numbered by Arabic or Roman digits).
%
% \changes{v2.0}{2006/11/06}{\cs{parindentFFN} not changed if
% already defined (required by JA for cah-gut.cls).}
%
% \changes{v2.3b}{2008/12/06}{New commands \cs{dotFFN} and
% \cs{kernFFN} for more flexibility (suggested by JA).}
%
% The value of |\parindentFFN| will be redefined at the
% |\begin{document}|, as the maximum of |\parindent| and 1.5em
% \emph{unless} it has been set in the preamble (the weird value
% 10in is just for testing whether |\parindentFFN| has been set
% or not).

% We save the standard definition of |\@makefntext| at the

% the value of flag |\ifFBFrenchFootnotes| (true or false).

%
% For compatibility reasons, we provide definitions for the commands
% dealing with the layout of footnotes in \frenchb{} version~1.6.
% \fbsetup{} (see in section \ref{ssec-keyval}) should be
% preferred for setting these options. |\StandardFootnotes| may
% still be used locally (in minipages for instance), that's why the
% test |\ifFBFrenchFootnotes| is done inside |\@makefntext|.

% to be switched on at |\begin{document}| and resetting the
% category code of \texttt{@} to its original value.
