% \thispackage provides a small number of user friendly macros to access features implemented in frequently used packages.
% Most of the macros are based on \xpackage{pgfkeys}, hence the ``\textt{key=value}'' syntax.
%
% \thispackage is mainly based on \xpackage{pgfkeys}\footnote{\noindent\xpackage{pgfkeys}:
% \href{http://www.ctan.org/tex-archive/graphics/pgf/base/generic/pgf/utilities}%
%      {\nolinkurl{CTAN:graphics/pgf/base/generic/pgf/utilities}}}
% and \xpackage{scrlfile} for its different modules are loaded \cs{AfterPackage}. \eTeX{} is required of course...
% Each interface is actually made as a separate module, which is loaded automatically after its \emph{master package}.
% Adding \usepackage*{interfaces} into your document preamble will make all modules active
% (\ie they will be loaded or not, depending on your document preamble).
% If you prefer not to use all modules, you can load them separately as a package, for example, type:
% \usepackage*{interfaces-titlesec} \textitbf{after} \usepackage{titlesec}.
% A better way is to add \usepackage*{interfaces-base} to your preamble, and then:\, \LoadInterface{titlesec,tocloft}\,
% indifferently before or after \usepackage{titlesec,tocloft}. Another possibility to restrict the modules
% is to give them as options for the main package:
% \cs[\lk]{usepackage}\M*[\xpackage{titlesec,tocloft}]\M*{{\pkgcolor interfaces}}.
%
% \thispackage[interfaces-base] is a mandatory ``module''. It loads \thispackage[interfaces-scrlfile],\,
% \thispackage[interfaces-etoolbox]\footnote{All macros in \thispackage[interfaces-etoolbox] are defined
% with \cs{providecommand} except \cs[\red]{removefromstart} which is used by \csref[\red]{repeatcell}.}\,
% and\, \thispackage[interfaces-pgfkeys]: those are the \emph{system-layer} of \thispackage.

% \cs[\red]{sectionformat} is a \xpackage{pgfkeys}-command for replacement of both \cs{titleformat} and \cs{titlespacing}.
% \textbf{If a key is not given, its value remains the same} while with \cs{titleformat} or \cs{titlespacing}, you must
% specify all values in a rigid order... Moreover, \cs[\red]{sectionformat} can be used concurrently
% with \cs{titleformat} and \cs{titlespacing} (although \cs{sectionformat} is deemed more comfortable, this
% allows to quickly modify some files written without \thispackage.)
%
% Keys corresponding to \TeX{} code (\key{font}, \key{before} or \key{after}) are associated with starred keys and \stform+ keys:
% they append their content to the previous value. Ex: \key{font}\stform+$=$\M*{\cs{larger}} adds \cs{larger} to the previous settings.
%
% For dimensions or skips, the \stform+ key adds, the \stform- key substract and the \stform* key scales.

%
% The features provided by \thispackage[interfaces-hypbmsec] are now independant
% of \xpackage{titlesec} and \thispackage[interfaces-titlesec].
%
% Package \xpackage{hypbmsec} provides extended sectionning commands with the syntax:
% \begin{Verb*}
%    \section$string(out$string)[toc]{title}     ($nnn or)    \section[toc]$string(out$string){title}
% \end{Verb*}
% Where:
% \begin{tabu}{&gt;{\ttfamily}rl}
%     \M*(out)   &amp;is used for the bookmark (outline)           \\
%     \M*[toc]   &amp;for tha table and contents and the marks     \\
%     \M*{title} &amp;to typeset the section title in the document
% \end{tabu}
%
%
% Internally, \xpackage{hypbmsec} defines \cs{hbs@bmstring} (the string used for the bookmark entry) and
% \cs{hbs@tocstring} (the string used for the table of contents and the marks).
%
% \thispackage takes advantage of this and defines:
% \begin{Verb*}
%  ($opt\lastsectiontitle)       ($nnn  expands to the title of the last) \section
%  ($opt\lastsectionbookmark)    ($nnn  expands to the text of the bookmark for the last) \section
%  ($opt\lastsectiontoc)         ($nnn  expands to the entry of the last) \section ($nnn in the table of contents)
%  ($opt\lastsectionanchor)      ($nnn  expands to the anchor name of the last) \section ($nnn if $xpackage(hyperref) is used)
% \end{Verb*}
%
% Macros for each sectionning command are defined:�
% \begin{tabu}{XXX}
% \cs[\opt]{lastparttitle}      &amp;\cs[\opt]{lastchaptertitle}      &amp;                                  \\
% \cs[\opt]{lastsectiontitle}   &amp;\cs[\opt]{lastsubsectiontitle}   &amp;\cs[\opt]{lastsubsubsectiontitle} \\
% \cs[\opt]{lastparagraphtitle} &amp;\cs[\opt]{lastsubparagraphtitle} &amp;                                  \\
% \end{tabu}
% with their \textt[\opt]{\textellipsis bookmark} and \textt[\opt]{\textellipsis toc} counterparts.
%
% Assignation to those macros is automatic. More precisely, \cs{lastsectiontitle} is defined {\bfseries after \cs{sectionbreak}}
% and {\bfseries before \cs{sectionmark}}: this means that in the fields \textt[\opt]{after} or \textt[\opt]{mark} of \csref{sectionformat},
% \cs{lastsectiontitle} has been updated yet. While in the fields \textt[\opt]{before}, and \textt[\opt]{break}, \cs{lastsectiontitle} is
% not yet updated. {\smaller(For chapters, this is the same if \xpackage{titlesec} formats the chapter
% titles, \ie if \cs{sectionformat}\cs{chapter} or \cs{titleformat}\cs{chapter} has been invoked. Otherwise,
% \cs{lastchaptertitle}, \cs{lastchapterbookmark} and \cs{lastchaptertoc} are set at \cs{stepcounter}\M*{chapter}.)}.
%
% Values are automatically reset to \csbf{relax} when a section of a superior level is created.
%
% This feature has been implemented essentially to make the use of a \cs{mark} command at \cs{sectionbreak} easier.
% Mark at \cs{sectionbreak} is important to get the correct behaviour for marks described in \thispackage[interfaces-marks]
% (page \pageref{marks} under \csref{ifmarksequal}). With this feature, when a new \cs{section} is created,
% \cs{lastsubsection} is reset to\, \csbf{relax}\, therefore,\, \cs{marksthecs}\M{subsection}\M{lastsubsection}
% will not mark anything.
%
% Another possibility is shown in this document: the header is clickable and has been defined with:
% \begin{Verb*}
% ($dr(\sectionformat))\section{
%           mark=($db(\marksthe)){section}{#1}
%                ($db(\marksthecs)){sectionanchor}{lastsectionanchor}
% }
% ($dr(\pagesetup)){

% ^^A\subsection{\cs{repeatcell}}
%
% \xpackage{makecell} provides \cs{eline}, \cs{nline}, \cs{Xrows} to fill a table with empty cells, or repeated rows.
%
% \thispackage extends the possibility with \cs{repeatcell}. Although it is of general use,
% \cs{repeatcell} should be used softly in order to keep the \xext{tex} document intelligible (see the examples below).
%
% {\def\${\textt[\pkgcolor]\textdollar}
% While repeating cells, \cs{repeatcell} can also make calculations with:
% \begin{itemize}
% \item \cs{numexpr},
% \item \$\cs{pgfmath}\$ (\csref{usetikz}\M*{{\opt pgfmath}} required in preamble)
% \item \$\$\cs{FPeval}\$\$ (\usepackage{fp} required in preamble) $\Rightarrow$ use \textt{round} to display the results!
% \end{itemize}
% Inside formulas \cs[\pkgcolor]{row} expands to the current row, \cs[\pkgcolor]{column} to the current column number (\cs{row} and \cs{column} are 1-based
% and relative to \cs{repeatcell}).
%
% \begin{declcs}[\red]{countvalues}\M{comma separated list}
% \end{declcs}

% \cs{countvalues}\M{comma separated list} expands to the number of values in the list. This is also the
% number of steps a \LaTeX{} \cs{@for} loop would do on the list: in other words, \textbf{empty values are counted}.
% \cs{countvalues} is provided to allow you to adjust automatically the number of columns of a tabular,
% depending on your data, with the\, \textasteriskcentered\, operator:\,
% \cs{begin}\M*{{\dg\underline{tabular}}}\M*{{\db\textt{\textasteriskcentered\M*{\cs[\red]{countvalues}\cs{list}}\M*{c}}}}.
%
% \cs{countvalue} is purely expandable in one expansion step. The \meta{comma separated list} is expanded once,
% exactly like in \LaTeX{} \cs{@for} {\smaller(\emph{hint:} you can put \cs{@empty} before, to avoid expansion).}

% \begin{declcs}[\red]{trunctext}\M[TruncateMarker]\M{width}\M{text}

% \cs[\red]{trunctext}\, is the same as\, \cs{truncate}\, but it leaves \M*{text} to its natural width

%   \cs[\red]{htruncadjust}\M*{4cm}\M*[2,1]\M*{Hello,world}\, will prepare the widths so that their sum does not exceed 4 centimeters,
% and\, $w_1 = 2 \times w_2$.
%
%   \cs[\red]{htruncadjust}\M*{4cm}\M*[2,1,2]\M*{The,World,Is flat}\, will prepare the widths so that their sum does not exceed 4 centimeters,
% and\, $w_1 = w_3 = 2 \times w_2$.
%
% If the optional parameters $x_i$ are not given, then they are equal to the natural width of \M*{text$_1$,$\ldots$,text$_n$}.
% In other words,\, \textt{text$_1$,$\ldots$,\textt{text$_n$}}\, are truncated to a width proportional to their natural widths.
% (And the sum of their widths will not exceed \meta{total width}).

%
% A new handler \handler/.blank/ is defined to allow automatic replacement of empty or blank values by the ``default'' value specified:

%              /base/path/my key=}     ($nnn produces)  The key was left blank!
% \end{Verb*}

% The following make blank value behave the same as default :
% \begin{Verb*}
%     \pgfkeys{/base/path/my key$handler/.blank/=\pgfkeysnovalue}
% \end{Verb*}
%
% And If you wish to forbid blank values you can add:
% \begin{Verb*}
%     \pgfkeys{/base/path/my key$handler/.value required/}
% \end{Verb*}
%
% With \thispackage[interfaces-pgfkeys] it is also possible to give a \handler/.default/ or/and a \handler/.blank/
% value to a handler, or on the other hand to say that a handler must have (\handler/.value required/)

% Original:

% \subsubsection{Default color}
%
% A trick about \cs{normalcolor}, which refers to \cs{default@color}:
%
% \cs{default@color} is not expressed in terms of a color model. Therefore, it is not
% possible to convert it into a universally correct parameter for the \cs{color} command.
% That's why, for example, \cs{bookmark} ignore blank parameter for \textt{color}: because
% it can do nothing with \cs{normalcolor} !
%
% Solution: if a color named ``\textt{default}'' has been defined in the preamble, then it is
% used as the default color. Otherwise, we define, \cs{AtBeginDocument} a color named ``default''
%
% If \xpackage{xcolor} is loaded, an assignment: \cs{colorlet}\M*{default}\M*{.} is made
% \cs{AtBeginDocument}. If only \xpackage{color} is loaded, then \cs{color}\M*{default}
% means \cs{color}\M*{\cs{default@color}} (this syntax is not admissible with \xpackage{xolor},
% but it works with \xpackage{color}).

%
%   \sectionformat\subsection[hang]{format=\large\bfseries}
%
%   \begin{Version}{2011/02/19 v3.1}\HistLabel{v3.1}
%   \item Recompilation of the documentation after \Xpackage{tabu} v2.5 release.
%   \end{Version}
%
%   \begin{Version}{2011/02/12 v3.0}\HistLabel{v3.0}
%   \item \csref{tocsetup}, \csref{lofsetup}, \csref{lotsetup} and \csref{listofsetup}: hooks:\\
%           \textt{multicols/beforebegin}\, \textt{multicols/afterbegin}\,  \textt{multicols/beforeend}\, \textt{multicols/afterend} \\
%           added.
%   \item New in \thispackage[interfaces-LaTeX]: \csref{quickprofile}.
%   \item Modification of \csref{papergraduate}: a non empty setting for \M*[every node\handler/.style/]
%         could make the graduation positions to be wrong.
%   \item New key in \thispackage[interfaces-enumitem]: \textt{first=} is an alias for \textt{start=}.
%   \item \cs{papergraduate}: though the graduations were right, the positionning of the graduated paper on the whole page was not.
%   \end{Version}
%
%   \begin{Version}{2011/01/19 v2.9}\HistLabel{v2.9}
%   \item Modification of the syntax of \csref{papergraduate} to allow the same syntax as \cs{path}.\\
%        + optional arguments for this command.
%   \item Some correction on \csref{tocsetup}: \cs{tocsetup}\M*{bookmark=bold} (for example) will automatically
%         set \cs{tocsetup}\M*{title=\cs{contentsname}} in no key \textt{title} has been set. Therefore, a bookmark
%         is set for the table of contents...
%   \end{Version}
%
%   \begin{Version}{2011/01/17 v2.8}\HistLabel{v2.8}
%   \item New: \csref{papergraduate} in \thispackage[interfaces-TikZ].
%   \end{Version}
%
%   \begin{Version}{2010/12/27 v2.6}\HistLabel{v2.6}
%   \item \csref{tocsetup}:\\
%         A few new aliases for keys. \\
%         Key \textt{columns/sep} didn't work. Fixed.
%   \item Generated file \xfile{interfaces-hypbmsec.code.tex} is empty since version \refVersion{2.5}.
%   \item Fixed a bug in \csref{usetikz}\M*{all}: \xpackage{pgfmath} should not be loaded twice because
%         of \cs{pgfmathdeclarefunction}... \\
%         + \xfile{pgfmodulesorting.code.tex} removed: bug in the code...
%   \item \thispackage[interfaces-TikZ] : keys \textt{shorten&gt;},\, \textt{shorten&lt;},\, and\, \textt{shorten&lt;&gt;}.
%   \item Optimisation.
%   \end{Version}
%
%   \begin{Version}{2010/12/07 v2.5}\HistLabel{v2.5}
%   \item \csref{sectionformat} now works with the \textt{explicit} option of package \xpackage{titlesec}.
%         (\emph{in} \thispackage[interfaces-titlesec])
%   \item Compatibility with \xpackage{calc} package as been implemented for \xpackage{pgfkeys} handlers: \par
%         \begin{tabu}{XXX}
%           \handler/.estore as dimen/ &amp;\handler/.estore as dimen in cs/ &amp;\handler/.store in dimen cs/ \\
%           \handler/.estore as glue/  &amp;\handler/.estore as glue in cs/  &amp;\handler/.store in skip cs/
%         \end{tabu} \par
%         As a result, it is now possible to write:
%         \begin{Verb*}
%         \sectionformat\section{labelsep=\widthof{ some text }}
%         \tocsetup{ section/pagenumbers/width=\widthof{ 00.00\enspace } }
%         \end{Verb*}
%         For scaling operations, \thispackage keeps the shrink and stretch components of glues,
%         while \xpackage{calc} discard them.
%   \item \csref{listofsetup} now works properly (\thispackage[interfaces-tocloft]).
%   \item Some \stform+ and \stform* keys added to \thispackage[interfaces-fancyhdr].
%   \item Fix a bug of \xpackage{titlesec} when inside \xext{dtx} files: \cs{input}\M*{ttlkeys.def}
%         shall be done with \% as a comment character (\cs{BeforeFile}...\cs{AfterFile} does the trick).
%   \end{Version}
%
%   \begin{Version}{2010/11/26 v2.4}\HistLabel{v2.4}
%   \item \thispackage[interfaces-fancyhdr] : complete key set for header, footer and offset settings \\
%         Now keys like \textt{foot/inner} or \textt{head/outer/offset} are available (ouf!).
%   \item \thispackage[interfaces-hypbmsec] has been completely rewritten and is now independant of \xpackage{titlesec}
%         and \xpackage{interfaces-titlesec}. \cs{lastsectiontitle} \etc are defined by the mean of
%         \cs{GetTitleString} (from H.O. eponym package). \\
%         \thispackage[interfaces-hypbmsec] now provides \cs{lastsectionanchor} when used with \xpackage{hyperref}.
%   \item \thispackage[interfaces-marks] revisited: expandable macros \cs{thefirstmarks}, \cs{thebotmarks} and \cs{thetopmarks}
%         are now expandable in exactly one step of expansion. \\
%         \cs{marksthe} and \cs{marksthecs} does not use \cs{unexpanded} (better for the \xext{log} file to see the marks). \\
%         Optimization for \cs{getthemarks} with incidence on \csref{ifmarksequal}.

% The \thispackage package provides a small number of macros to modify the settings of a
% large number of parameters provided by Most Frequently Used Package (MFUP) for typesetting
% beautiful document with \LaTeX{}.
%
% \thispackage is organised as different modules which are loaded after the master package is loaded.
% Each module can be loaded separately.
%
% \cs{sectionformat}: interface for package \xpackage{titlesec} to modifies the titles
%  produced by the sectionning commands (and their bookmarks).
%
% \cs{pagesetup}: interface for package \xpackage{fancyhdr} to modify the current page style
%  or create new page styles.
%
% \cs{tocsetup}: interface for package \xpackage{tocloft} to fine tune the aspect of the table of contents,
% list of figures / of tables. \cs{tocsetup} also applies to \cs{shorttableofcontents} provided
% by the \xpackage{shorttoc} package.
%
% \cs{repeatcell}: to create `dynamic' tabulars, possibly with formula computation (\cs{numexpr},
% \cs{pgfmathparse} or \cs{FPeval} formulas can be plugged in the tabular or array).
%
% \cs{rowfont}: to modify the font and/or the alignment of each cell in a tabular/array row.
%
% + some macros to make easier the use of \eTeX{} \cs{marks} registers (useful with \cs{sectionformat}
% and \cs{pagesetup}).
%
% \thispackage is mainly based on scrlfile.sty (provided in the Koma-Script bundle, but
% Koma-Script classes are not required), on pgfkeys and etoolbox.
%
% \thispackage defines some pgfkeys handlers designed specially to make key-value interface
% for other packages. Using those handlers allows to make an interface in a few minutes...
