+The 'Help' part of \bbStudio is used to browse the html help of \BBTKns. You can find there various guides (see section~\ref{sec:guides}) and detailed information about each black box available (see section~\ref{sec:boxes_help}). They can be browsed alphabetically, by package and by category. Two special categories, demos and examples, are available via direct links (see section~\ref{sec:demos_examples}).
% ==========================================
+% ==============================================
+\subsection{Online Help}
+% ==============================================
+
+Various levels of help are supplied by \bbStudions.
+
+% ==========================================
+\subsubsection{Command-line help}
+% ==========================================
+
+
+The 'working' area (the left one, as opposed to the (\texttt{Help}) area, on the right side) is composed of:
+one single line area (\texttt{Command}), at the bottom, in which you can enter your commands, and
+a multiple line zone (\texttt{Messages}) in which the command interpreter prints out the result of your commands.
+%The upper part contains the script editor; we shall not use it right now, you may reduce it.
+Command-line help for the black box scripting language \bbs (see section \ref{Scripting}) can be obtained in this zone. \par
+As mentioned above, the command (or button) \texttt{help} permits to print in the \texttt{Message} zone the list of all recognized commands, while the command \texttt{help} \emph{command\_name} displays in this zone the help about the selected command.\par
+The command \texttt{help} \emph{package\_name} displays in the \texttt{Message} zone a short information about the selected package, provided that this package was previously loaded (Note that you can know which packages were loaded by executing the command \texttt{help packages}). Furthermore, it simultaneously displays in the right zone (\texttt{Help}) the corresponding full html help available.\par
+In a similar way, one can obtain the information about any box from the loaded packages, by executing the command \texttt{help} \emph{box\_name}. Note that some boxes may be unavailable if the command \texttt{load} was used to load the package, since this command only loads the boxes defined in binary files (dynamic libraries). Some boxes are defined in script files. To be sure that all the boxes from the package are loaded the command \texttt{include} is to be preferred.\par
+
+It is important to note that the black boxes are implemented and have to be used according to the {\bf\emph{object-oriented}} programming principles. This means that you have to make difference between a black box {\bf\emph{type}} and an {\bf\emph{instance}} of the given black box type. The former defines a ``pattern'' (a mold), according to which are formed the actual objects. If you query for help on a black box type, you learn about its purpose, its author, the boxes it contains (if it is a complex black box) and the types of its inputs/outputs. The user-defined black box types belong to the package \texttt{user} and can be listed by use of the command \texttt{help user}. If you query for help on a black box instance, you learn about the values and the state of its inputs/outputs. The currently existing black box instances belong to the complex black box \texttt{workspace} and can be listed by use of the command \texttt{help workspace}.

+% ==========================================
+\subsubsection{Guides}
+\label{sec:guides}
+% ==========================================
+
+All the guides can be browsed in html version in the \texttt{Help} part of \bbStudions. Their pdf versions (except Doxygen documentation) can be retrieved from:\\
+\url{http://www.creatis.insa-lyon.fr/creatools/documentation}
+
+ \begin{itemize}
+ \item {\bf\emph{User's Guide}}: This guide!
+ \item {\bf\emph{Package Developer's Guide}}: Step-by-step "How-to" for programmers who want to create their own
+ black boxes/packages.
+ % \item {\bf\emph{Developper's Guide}}: For bbtk kernel developpers only. (This one is probably not very much
+ % up-to-date, since we spend more time in developping than writing documentation that's not of user concern).
+ % \item {\bf\emph{Reference Manual}}: Contains a exaustive description of all the features for all the commands.
+ %\item {\bf\emph{Booklet}}: Vade mecum.
+ \item {\bf\emph{Doxygen Documentation}}: Doxygen source browser.\\ Automatically generated from source files. Should only concern the kernel developers.

+
+
+
+
+% ==========================================
+\subsubsection{Boxes Help}
+\label{sec:boxes_help}
+% ==========================================
+ Lists of currently available boxes from installed packages, sorted according to the following criteria:
+ \begin{itemize}
+ \item {\bf\emph{Alphabetical list}}%: This is the 'zero-level' of retrieving.
+ \item {\bf\emph{List by package}}%: The boxes are indexed by package they belong to
+ \item {\bf\emph{List by category}}:
+ Each box is indexed by a list of keywords, called 'categories', such as '\texttt{read/write}',
+ '\texttt{filter}', '\texttt{viewer}', ...
+ A given box may belong to more than one \texttt{category}, however some categories are mutually exclusive.
+ Standard categories are:
+ \begin {itemize}
+ \item\texttt{atomic box}/\texttt{complex box}\\
+ Any box is either atomic or complex.\\
+ The former are 'atomic' units written in C++ and available in binary form.\\
+ Any pipeline built up as an assembly of several black boxes (atomic or complex), and described in \bbs script language is itself viewed as a complex black box, and hence tagged as belonging to the latter category.
+ \item\texttt{example} / \texttt{demo} / \texttt{application} (see \ref{sec:demos_examples})\\
+ These ones are scripts that produce a result when executed (i.e. they
+ execute a pipeline), as opposed to the scripts that only define complex boxes but do not instanciate and execute boxes.
+ \begin {itemize}
+ \item\texttt{example}: It is just a (simple) example, for programmers, of how to use a given feature. The \texttt{Examples} link on the starting page links to the list of the boxes of this category.
+ \item\texttt{demo}: It can be a 'good looking' (a.k.a 'sexy') example of some sophisticated work, done only by using \texttt{bbtk}. The \texttt{Demos} link on the starting page links to the list of the boxes of this category.
+ \item\texttt{application}: It is a final application, end-user intended (e.g. association of a DICOM image browser, reader, viewer with some interaction and processing)
+ \end {itemize}
+ \item\texttt{widget}: A piece of graphical interface (based on \texttt{wxWidgets}).
+ \item\texttt{dicom}: A box related to medical images in Dicom format.
+ \item\texttt{viewer}: A box allowing to view something (e.g. an image).
+ \item\texttt{read/write}: An I/O-related box.
+ \item\texttt{mesh}: A mesh-related box.
+ \item\texttt{filter}: A filter, mainly image filters.
+ \item\texttt{image}: An image-related box.
+ \item\texttt{3D object creator}: A box which creates a 3D object to be injected into a 3D view (e.g. a plane, a surface).
+ \item\texttt{math}: Maths of course.
+ \item\texttt{misc}: Miscellaneous...
+ \end {itemize}
+ Remark that the list of categories is 'auto-extensible': each time a new box is created which belongs to a new category and the boxes list is regenerated, the new category appears in the list, holding the new box. The above list only contains the categories used in the packages provided with current \bbtk release.
+ \item {\bf\emph{List of adaptors}}: The adaptors are a special type of black boxes that are used internally to perform type conversions. Although they are not end user intended, you may see their list. Adaptors belong to the \texttt{adaptor} category.
+ \end {itemize}
+ For each box, the html \texttt{Help} provides the informations necessary to use it: its name, its purpose, the descriptions of its inputs/outputs and the name of the package (or script file) that is to be loaded. Note that for a given box only the inputs/outputs listed in white cells are of actual interest. The remaining ones, grouped after them in colored cells, are standard (have the same names and purpose) in all atomic boxes. Additionally, for all boxes but the atomic ones (i.e. for all boxes defined in \bbs script language), the corresponding script is available via [\texttt{source}] link. Actually, by clicking on this link, one loads the script into the \texttt{Files} area where it can be analyzed, edited and executed.
+
+% ==========================================
+\subsubsection{The Package Browser}
+\label{Package_Browser}
+% ==========================================
+
+The package browser is a standalone application \texttt{bbPackageBrowser}, which
+dynamically loads and queries the available packages.
+It is thus a smarter tool than the static html documentation.
+You can run it independently or from \bbStudio using either the button labeled \texttt{Start Package Browser} of the 'Command' part or the corresponding entry in the menu 'Windows'.
+Note that it may take some time to start because it loads all available
+packages at start.
+Its appearance is reproduced in figure \ref{imPackage_Browser}.
+
+\begin{figure}[!ht]
+\caption{The Package Browser}
+\begin{center}
+\includegraphics[width=0.6\textwidth]{Package_Browser.png}
+\end{center}
+\label{imPackage_Browser}
+\end{figure}
+
+It allows you to find boxes by use of a multi-criteria filtering principle:
+the boxes listed are the ones the attributes of which match \emph{all} the
+words entered in the 'Filter' part.
+You can get the whole description of a given box by clicking on its name.
+\\
+Warnings:
+
+\begin{itemize}
+\item It is case sensitive, i.e '\texttt{Button}'
+will give different results than '\texttt{button}'.
+\item After typing a filtering string, you have to validate it by pressing the 'Enter' key, in order to update the display of the boxes list.
+\item A filtering string only needs to match a subpart of the related attribute of a box.
+For example, entering 'utt' in the 'Name' attribute will match a box called 'Button'.
+\end{itemize}
+
+Attributes:
+
+\begin {itemize}
+\item \texttt{Package}: The name of the package to which the box belongs (e.g. \texttt{wxvtk}, \texttt{std}).
+\item \texttt{Name}: The name of a box or an application (e.g. \texttt{Reader}, \texttt{example}).
+\item \texttt{Description}: A part of the description of a box (e.g. \texttt{3D}, \texttt{image}).
+\item \texttt{Category}: The categories of the box (e.g. \texttt{demo}).
+\item \texttt{Input/Output Type}: The \CPP type of an input or output (e.g. \texttt{vtkImageData*}, \texttt{std::string}).
+\item \texttt{Input/Output Nature}: The \texttt{nature} of an input or output (e.g. \texttt{file name}, \texttt{signal}).

-\subsubsection{Command line help}
-% ==========================================
-
-
-The 'working' area (the left one, as opposed to the 'help' area, on the right side) is composed of :
-one single line area (\texttt{Command}), at the bottom, in which you can enter your commands and
-a multiple line zone in which the Command interpreter prints out the result of your commands.
-%The upper part contains the script editor; we shall not use it right now, you may reduce it.
-Command line help for the black box scripting language (\bbsns) can be obtained
-in this zone (see \ref{Scripting}).
-

- \item {\bf\emph{User's Guide}} : This guide !
- \item {\bf\emph{Package Developper's Guide}} : Step to step How-to for programmer who wants to create his own
- black boxes/packages.
- % \item {\bf\emph{Developper's Guide}} : For bbtk kernel developpers only. (This one is probably not very much

-% ==========================================
-\subsubsection{Boxes Help}
-% ==========================================
- Lists of currently available boxes from installed packages
- \begin{itemize}
- \item {\bf\emph{Alphabetical list}} : %This is the 'zero-level' of retrieving.
- \item {\bf\emph{List by package}} Boxes indexed by package
- \item {\bf\emph{List by category}} :
- Each box is indexed by a list of keywords, called 'categories', such as '\texttt{read/write}',
- '\texttt{filter}', '\texttt{viewer}', ...
- A given box may belong to more than one \texttt{category}, however some categories are mutually exclusive.
- Standard categories are :
- \begin {itemize}
- \item\texttt{atomic box}/\texttt{complex box}\\
- Whether it's an 'atomic' unit written is C++ and available in binary form in a package or it's an assembly of several black boxes (atomic or complex) which is described in \bbs script language.\\
- Any box is either atomic ou complex.\\
- Any pipeline described in a \bbs script is itself viewed as a complex black box hence is tagged as belonging to this category.
- \item\texttt{example} / \texttt{demo} / \texttt{application}\\
- These ones are scripts which produce a result when executed (i.e. they
- execute a pipeline like \texttt{exampleSlider} above), as oposite to the scripts which only define complex boxes but do not instanciate and execute boxes.
- \begin {itemize}
- \item\texttt{example} : It's just a (simple) example, for programmers, on how to use a given feature. The \texttt{Examples} link on the starting page links to the list of the boxes of this category.
- \item\texttt{demo} : It can be a 'good looking' (a.k.a 'sexy') example on some sophisticated work, done only by using \texttt{bbtk}. The \texttt{Demos} link on the starting page links to the list of the boxes of this category.
- \item\texttt{application} : It's a final application, end user intended (e.g. Subscale a huge volume without loading it in memory, Crop a DICOM image, etc.)
- \end {itemize}
- \item\texttt{widget} : A piece of graphical interface (based on \texttt{wxWidgets})
- \item\texttt{dicom} : Dicom medical image-related box.
- \item\texttt{viewer} : A box allowing to view something (e.g. an image).
- \item\texttt{read/write} : An I/O-related box
- \item\texttt{mesh} : A mesh-related box
- \item\texttt{filter} : A filter, mainly image filters.
- \item\texttt{image} : An image-related box
- \item\texttt{3D object creator} : A box which creates a 3D object to be injected into a 3D view (e.g. a plane, a surface).
- \item\texttt{math} : Math
- \item\texttt{misc} : Miscellaneous...
- \end {itemize}
- Remark that the list of categories is 'auto-extensible' : each time a new box is created which belongs to a new category and the boxes list is regenerated, then the new category appears in the list, holding the new box. The above list only contains the categories used in the packages provided with current \bbtk release.
- \item {\bf\emph{ List of adaptors}} : The adaptors are a special type of black box which are used internaly to perform type conversions. Thought there are not end user intended, you may see their list. Adaptors belong to the \texttt{adaptor} category.
- \end {itemize}
-
-% ==========================================
-\subsubsection{The Package Browser}
-\label{Package_Browser}
-% ==========================================
-
-The package browser is a standalone application which
-dynamically loads and queries the available packages.
-It is thus a smarter tool than the static html documentation.
-You can run it with the command \texttt{bbPackageBrowser}
-or in \bbStudio using either the button of the 'Command' part
-or the menu entry 'Windows$>$Start Package Browser'.
-Remark that it may take some time to start because it loads all available
-packages at start.
-Its appearance is reproduced in figure \ref{imPackage_Browser}.
-
-\begin{figure}[!ht]
-\caption{\label{imPackage_Browser}The Package Browser}
-\begin{center}
-\includegraphics[width=0.6\textwidth]{Package_Browser.png}
-\end{center}
-\end{figure}
-
-It allows you to find boxes using a multi-criteria filtering principle :
-The boxes listed are the one whose attributes match \emph{all} the
-words entered in the 'Filter' part.
-You can get the whole description of a given box clicking on its name.
-
-Warnings :
-
-\begin{itemize}
-\item It's case sensitive, i.e '\texttt{Button}'
-will give different results than '\texttt{button}'
-\item You have to press enter in the filter zone to update the boxes list
-\item A filtering string only has to match a subpart of the related attribute of a box.
-For example, entering 'utt' in the 'Name' attribute will match a box called 'Button'.
-\end{itemize}
-
-Attributes :
-
-\begin {itemize}
-\item Package : The name of the package to which the box belongs (e.g. \texttt{wxvtk}, \texttt{std})
-\item Name : The name of a box or an application (e.g. \texttt{Reader}, \texttt{example})
-\item Description : A part of the description of a box (e.g. \texttt{3D}, \texttt{image})
-\item Category : The categories of the box (e.g. \texttt{demo})
-\item Input/Output Type : The \CPP type of an input or output (e.g. \texttt{int}, \texttt{vtkImageData*}, \texttt{std::string})
-\item Input/Output Nature : The \texttt{nature} of an input or output (e.g. \texttt{file name}, \texttt{signal})

+You get information about the actual instance \texttt{a} of the box type \texttt{std::Add}. It gives something like this:
+\begin{verbatim}
+> help a
+ Black Box 'a' <std::Add>
+ * Inputs :
+ 'BoxExecute' = '? (no adaptor found)' [Modified]
+ 'BoxProcessMode' = 'Pipeline' [Modified]

+ 'In2' = '0' [Modified]
+ * Outputs :
+ 'BoxChange' = '? (no adaptor found)' [Out-of-date]
+ 'Out' = '0' [Out-of-date]
+\end{verbatim}
+Note that the inputs appear as \texttt{[Modified]}, since the code defining the box type includes an initialization of the inputs. On the other hand, the outputs appear as \texttt{[Out-of-date]}, as the box has not yet been executed and therefore its outputs have not been updated. See the second part of this section to learn more about the updating. For a moment, just note that one way to process the box \texttt{a} is to use the command:
+\begin{verbatim}
+> exec a
+\end{verbatim}
-You can see that \texttt{Add} boxes have two inputs,
-with name \texttt{In1} and \texttt{In2},
-and an output, with name \texttt{Out}.
+This command does not display anything (except if the
+box itself displays something in its processing).
+It just processes the box if needed. In our case, the result can be seen as follows:
+\begin{verbatim}
+> exec a
+> help a
+ Black Box 'a' <std::Add>
+ * Inputs :
+ 'BoxExecute' = '? (no adaptor found)' [Up-to-date]

+ 'In2' = '0' [Up-to-date]
+ * Outputs :
+ 'BoxChange' = '? (no adaptor found)' [Up-to-date]
+ 'Out' = '0' [Up-to-date]
+\end{verbatim}
+Note the change of status of all the inputs and outputs (\texttt{[Up-to-date]}).
+In practice, the command \texttt{exec} is useful to execute boxes that do not have any output,
+such as boxes that write something to a file or, display a
+graphical interface, and so on.

+
+This is an elementary DICOM-image slicer (fig.~\ref{fig:simpleslicer}) designed to view 3D medical images slice-by-slice. The image is to be composed of a series of DICOM files contained in a separate directory. The index of the slice to be displayed is selected by means of a slider. The command \texttt{connect slider.BoxChange viewer.BoxExecute} permits the Viewer to update the display every time the output of the Slider changes. The command \texttt{set slider.ReactiveOnTrack 1} on its turn makes that the output of the Slider changes every time its cursor is moved, while the default behavior is to change only when the mouse-button is released after moving the cursor.\\

+
+Despite its simplicity, this application may already be useful. If you want to reuse it, you have to save the \bbs commands in a text file. The conventional (and mandatory) extension for such script files is \texttt{bbs}
+(black box script). For example, our elementary 3D DICOM-image slicer
+can be defined in the following file:

+\end{file}
+
+Lines starting with a \texttt{\#} character or with double slash (\texttt{\//\//}) are ignored, they
+are considered as comments by the interpreter. A longer comment can be placed between the marks \texttt{\//*} and \texttt{*\//}. Each of this mark is to be placed alone in a separate line, like in the example.\par
+
+To use this file in \bbStudions, click on the \texttt{include} button, and browse your filestore to find the file. You can also type the command:
+
+\begin{verbatim}

-Once you have defined a new type of complex box, you
-may like to reuse it. To do this, you can simply
-write the \bbs commands defining the new box
-into a text file and afterwards include that file in \bbins.
-Doing this, you start writing \bbs scripts.
-The conventional (and mandatory) extension for such scripts is \texttt{bbs}
-(black box script).
-For consistency reasons, you are requested to prepend \texttt{bb} to the name.
-
-For example, the \texttt{Add3} complex box we previously worked on
-can be defined in the \texttt{bbAdd3.bbs} file :
-
-\begin{file}{bbAdd3.bbs}
-\begin{verbatim}
-# Defines the Add3 black box which adds 3 doubles
-load std
-
-define Add3
- # I am the author
- author "myself"
- description "adds 3 doubles"
- # Pipeline creation
- new Add a
- new Add b
- connect a.Out b.In1
- # Inputs definition
- input x a.In1 "first double to add
- input y a.In2 "second double to add
- input z b.In2 "third double to add"
- # Output definition
- output result b.Out "output"
-endefine
-\end{verbatim}
-\end{file}
-
-Lines starting with a \texttt{\#} character or a \texttt{\//\//} character are ignored, they
-are considered as comments by the interpreter.
-To use this file in \bbStudions, click on the \texttt{include} button, and browse your filestore to find the file.
-
-\begin{verbatim}
-> include bbAdd3.bbs
-> help Add3
-Complex Black Box <user::Add3>

-\subsection{Creating command line applications}
+\subsubsection{Creating and using command-line applications}
\label{bbi-command-line-app}
% ==========================================
-Now that you know how to create complex black boxes
-(with \texttt{define/endefine}), think
-back to the \texttt{workspace} object.
+Command-line applications are those that can be executed by typing, in a console, the name of the application and the values of its parameters. The Linux users are very familiar with this way of working, while the Windows users are not, since they are used to execute the applications by clicking on the corresponding icons. Nevertheless, the command-line execution of the applications is feasible (although not very useful) in Windows. You just need to invoke the black ``console'' available either via \texttt{Start > Execute > cmd}, or via \texttt{Start > Programs > Accessories > Invoke commands}. Furthermore, command-line execution of applications is very useful in both environments in such cases as batches.
+
+You already know how to write script files that define stand-alone pipeline applications.
+In fact, these applications \emph{can} be executed directly from the console by typing:
+\begin{verbatim}
+> bbi <application-name>
+\end{verbatim}
+Note that this execution mode invokes the interpreter \texttt{bbi} and passes the name of the application to the interpreter.
+
+So, what more do you need to know? A command-line application may need some inputs. In order to define them, you need to use the (already known) command \texttt{input}.
+
+To understand the underlying mechanism let us think back of the \texttt{workspace} object.
Remember that it is also
a \texttt{complex black box}.
-Actually, when you type interpreter commands
-outside a \texttt{define/endefine} block,
+Actually, when you write \bbs commands
+outside of a \texttt{define/}\texttt{endefine} block,
you progressively define the \texttt{workspace}
complex black box.
-You can think of it like if at start the interpreter
+You can think of it as though at start the interpreter
was issuing a command \texttt{'define workspace'}
and then letting you define the interior of the box
\texttt{workspace}.
-Remember that the command \texttt{inputs}
+Remember that the command \texttt{input}
allows to define an input of a complex box.
Now, if you use the command \texttt{input}
outside a \texttt{define/endefine} block then
This input will then be connected to the
parameters that the user passes to the command line.
-For example, consider the script :
+For example, consider the script:
\begin{file}{add.bbs}
\begin{verbatim}
The third and fourth lines define two inputs \texttt{x}
and \texttt{y}. When you execute this script,
-you can pass these two arguments on the command line,
-like this :
+you can pass these two arguments in the command-line,
+like this:
\begin{verbatim}
> bbi add x=1 y=1
x+y=2
\end{verbatim}
-You can also invoke \bbi the option \texttt{-h},
-which gives help on the \texttt{workspace} box :
+You can also note that, in the command-line context, you can invoke \bbi with the option \texttt{-h},
+which gives help on the \texttt{workspace} box:
\begin{verbatim}
> bbi add -h
'y' <double> : second number to add
\end{verbatim}
-To get a better help, use the \texttt{description}
-and \texttt{author} commands :
-
+This is particularly useful to learn about the usage of the application, namely about the inputs that are to be set at execution. To improve the help provided, use the \texttt{description}
+and \texttt{author} commands in the script file defining the application:
+\\
+\\
\begin{file}{add.bbs}
\begin{verbatim}
description "Adds two numbers"
Note that for both \texttt{-t} and \texttt{-g} options,
the input from the user is a \texttt{string} and
\bbi converts it to the right input type using
-an \texttt{adaptor}, hence the right adaptors must be loaded.
