This directory contains the package
name: knowledge
license: LaTeX Project Public License version 1.2 or above
version: v1.28
date: 2022/02/12
author: Thomas Colcombet
mail: thomas.colcombet@irif.fr
web: https://ctan.org/pkg/knowledge
### Purpose:
The knowledge package for LaTeX offers a systematic way to handle
notions/concepts/terms throughout a document. In combination with
`hyperref`, it is used for easily handling links inside a document (every
use of a concept is linked to its introduction), or outside the document
(for centralizing the url's in a separate part). It also helps building an
index, and deals with scoping of concepts as well as mathematics.
It is designed to--as much as possible--not interfere with the writing of
the document.
### Install:
It is sufficient to have the file knowledge.sty accessible by LaTeX.
It can be produced by `make knowledge.sty` if necessary.
The documentation is in the file `knowledge.pdf`.
A starting example can be found in `knowledge-example.tex`.
### Content of knowledge-sources.zip:
- README.md: this file generated while compiling knowledge.ins,
the content is in knowledge-code.dtx
- knowledge.sty: the package file (generated using knowledge.ins)
- knowledge.pdf: the user documentation (generated by compiling
knowledge.tex)
- knowledge.tex: the tex file producing the knowledge.pdf.
- makefile: the makefile. Use 'make all' to generate knowledge.sty
and knowledge.pdf. It can also: clean the directory, make zip
version of the sources, or ready for CTAN.
- knowledge.ins: is the file generating knowledge.sty and
README.md from knowledge-code.dtx (using docstrip).
- knowledge-code.dtx: most of the code. Can be compiled to
provided a longer documentation.
- knowledge-configuration.dtx: file containing part of the configuration.
- knowledge-utils.dtx: file containing several pieces of code not really
related specifically to knowledge
- knowledge-example.tex: an example file.

% \subsection{Option and packages}
%
%
% \subsubsection{Configuration option}
%
% The options exist in two forms, the one that usable during the loading of the package,
% and the one that can be used in \cs{\knowledgeconfigure}, i.e., at some other locations in the document.
% The configuration options can be used when loading the package, however, these are first
% appended to the tl variable \csintro{\knowledge_configuration_pending_tl}, and executed at the end of the loading.
% This is important, since automatic configuration needs, for instance, to know if the \kl{composition mode}, or the \kl{paper mode} is used right now, but one cannot expect the user to declare the options in this particular order.
%
% \ToImprove{I do not know why, but \cs{\ProcessKeysOptions} removes the spaces in the parameters.
% So we have to do the same if we want to load options this way. This does not seem canonical.}
%
% We first provide a token list that stores the configurations (which are different from the options).
% \begin{macrocode}
\tl_clear_new:N\knowledge_configuration_pending_tl
% \end{macrocode}
%
%
% \paragraph{Configuration options}
% We provide here the code that is used to create new options for \cs{\knowledgeconfigure}.
% At the same time, it sets at package loading these options to be `posponed' (these will be executed)
% when the package loading is completed.
% \begin{macrocode}
\newrobustcmd\knowledgeconfigure[1]{
\keys_set:nn{ knowledge~configuration~options }{#1}

% \csintro{\KnowledgeConfigureBooleanOptionTF}[\cs{optional_bool}]\{option name\}\par
% ~~~~~~~~\{true code\}\{false code\}
% \end{quote}
% It takes an optional bool (of \kl(package){expl3}) and the name of the configuration option.
% The option is defined both in \cs{knowledge~package~options},
% and in \cs{knowledge~configuration~options}.
% In the former case, the option is simply appended to \cs{\knowledge_configuration_pending_tl} for
% being executed at the end of package loading.

% \subsubsection{Data structures}
%
% Several `data structures' are used internally by the package.
% \begin{description}
% \item[\kl{areas}] are zones structuring valid documents. These are typically
% `\texttt{document}', `\texttt{scope}', `\texttt{section}', `\texttt{subsection}', `\texttt{theorem}', `\texttt{itemize}', `\texttt{item}' and so on.
% \item[\kl{categories}] are collections of \kl{areas} that share some common behaviours, for instance, the \kl{category} `\texttt{itemize-like}' will aggregate
% `\texttt{itemize}', `\texttt{enumerate}' \kl{areas}. In particular an `\texttt{item}'
% \kl{area} is required to have a parent that belongs to the \kl{category} `\texttt{itemize-like}'.
% \item[\intro{instances}] are the realization of \kl{areas} in a document. Hence `section' is an \kl{area},
% but each section of a document is an \kl{instance}.
% \item[\intro{scopept instances}] stands for `phase two'. These are functions that are activated during
% the second compilation. (and also, under implementation, in the preamble)
% \item[\kl{knowledges}] are the central notion
% \end{description}
%
% \paragraph{Areas}
%
% An \intro{area} is an environment unit such as `\texttt{theorem}', `\texttt{section}', and so on\dots{}
% Special realization of these \kl{areas} are called `\kl{instances}'.
% Hence, there is an \kl{area} named `\texttt{section}', and there are potentially
% many \kl{instances} of this area in the document.
% Part of the machinery is used for the allocation of \kl{instances}.
% In some sense, this is a weak form of grammar describing how these can be used.
% For instance, a subsection has to occur below a section, and opening a section immediately
% closes the current subsection if it exists.
%
% To help the definition, the areas can be grouped into categories in order to share part of the code/definitions.
% Each time an \kl{area} is defined, a corresponding \kl{category} with same name is also defined.
%
% An \kl{area} has some fields. The field X of \kl{area} A
% can be found in the token of name |\scope_tl.area[A].X|.
% \begin{compactdesc}
% \item[\csintro{nesting_int}] is an int counting the nesting level of the area at the current moment.
% \item[\csintro{count_int}] is an int counting the instances of the area opened so far. It is used (for the moment)
% in order to uniquely name the instances. It is also used in some tests. It is incremented each time
% a new \kl{instance} of this area is created.
% \item[\csintro{name_tl}] is the text name of the \kl{area}.
% \item[\csintro{pushcode_tl}] is code to be executed when an \kl{instance} of the \kl{area} is created.
% \item[\csintro{popcode_tl}] is code to be executed just before an \kl{instance} of the \kl{area} is closed.
% \item[\csintro{autoclose_bool}] is a boolean which, when set to true,
% means that \kl{instances} of this area may be implicitly closed. This is the case for instance
% for a `subsection', which can be implicitly closed when another `subsection' is started, or when
% a `section' is started, or when the document finishes.
% \item[\csintro{recursive_bool}] is a boolean describing whether such an environment can be opened inside itself.
% This is more for making the error messages explicit.
% \item[\csintro{multiple_bool}] is a boolean that tells whether several instances of this area can be defined
% in the document. This is also mainly for making more explicit the error messages.
% \item[\csintro{forces_tl}] is the name of an area that has to be opened if one wants to use this area.
% It is opened if necessary.
% \item[\csintro{acceptsknowledge_bool}] is a boolean telling whether a knowledge can be associated to an instance of this area.
% \item[\csintro{labelizable_bool}] tells whether a label can point to such an environment.
% \item[\csintro{attractsknowledge_bool}] is a boolean that tells whether this area
% spontaneously catpures the \kl{knowledges} defined in its scope.
% Hence, a section does not attract knowledges: the document does.
% However, the user can force a knowledge to only be valid in a section since `section's accept knowledges.
% \item[\csintro{mandatorybase_seq}] is a \texttt{seq} containing the list of categories that are allowed to
% be the parent of this area. For instance, \cs{\item}
% would have \texttt{itemize}, \texttt{compactdesc} and \texttt{enumerate}.

% \subsubsection{Inspecting}
%
% \csintro{\scope_get_attractive_instance:N} takes a \kl{token list variable},
% and sets it to contain an
% instance able to receive knowledges.
% This is done by inspecting the scope stack until reaching an instance
% that has \kl{instance.attractsknowledge_bool} set to true (by default, this is `base').
% \begin{macrocode}

}
% \end{macrocode}
% \csintro{\scope_get_labelizable_instance:N} takes a token list variable as input for holding the result.
% It inspects the current stack of instances \cs{\scope_instances_stack_seq}, searching for an "instance"
% of a "scope" which is labelizable, and returns it. The default is `base'.
% \begin{macrocode}

{\tl_set:Nn#1{##1}\seq_map_break:}{}}
}
% \end{macrocode}
% The command \csintro{\knowledge_scope_track_instance:Nn} is the internal part od the "scope=" directive.
% It takes as argument a token list variable for holding the result, and a text to be looked for.
% If the text corresponds to a "scope" name (such as section, theorem, \dots), then it inspects the
% content of the stacks for finding the target.
% Otherwise, it uses it as a label.
% and if it fails, it tries to find a label of this name that provides an instance.
% \begin{macrocode}

% \subsubsection{Scope tags}
%
% \AP A ""scopetag"" is a name that can be used to identify a family of "instances" that correspond to it.
% It gets to have two variables attached to it:
% \begin{description}
% \itemAP[\cs{\knowledge_scopetag_tl}\texttt{{[TAG]}\_bool}] which tells whether it
% has been officially declared (it is false if it has been used but not declared by a \cs{\knowledgescope}
% or a \cs{\label} command).
% \itemAP[\cs{\knowledge_scopetag_tl}\texttt{{[TAG]}\_seq}] is a sequence of
% "instances" that are attached to it. It always contains (as soon as created) \textbf{explicit-scope:}\texttt{TAG}.
% \end{description}
%
% In order to identify scopes, the command~\cs{\knowledgescope} (or \cs{\label} which is overloaded for this purpose).
%
% \par\noindent\AP\csintro{\knowledge_scopetag_tl} is a unique string for identifying "scopetags".
% \par\noindent\AP\csintro{\knowledge_scopetag_if_exist:nTF} tests the existence of a "scopetag".
% \par\noindent\AP\csintro{\knowledge_scopetag_ensure:n} guarantees that the "scopetag" is defined (by default, the boolean is set to false).
% \par\noindent\AP\csintro{\knowledge_scopetag_warn_if_unknown:n} writes \cs{\KAuxUndeclaredScopeTag} to the "kaux file" if the "scopetag" was never met before, then calls \cs{\knowledge_scopetag_ensure:n}.
% \par\noindent\AP\csintro{\knowledge_scopetag_declares:n} creates the "scopetag" if necessary, and if it was not known before, declares and puts a \cs{\KAuxDeclaredScopeTag} command in the "kaux file".
% \begin{macrocode}
\tl_const:Nn\knowledge_scopetag_tl{ScpT@g}

{\bool_gset_true:c{\knowledge_scopetag_tl[#1]_bool}}
\KAuxWriteX*{\exp_not:N\KAuxDeclaredScopeTag{#1}}
}
% \end{macrocode}
% \AP The command \csintro{\knowledgescope} associates an "instance" to one or more "scopetags":
% \begin{macrocode}
\NewDocumentCommand\knowledgescope{ >{\SplitList{,}}m }{
\kl_hide_begin:\group_begin:
\ProcessList{#1}\knowledge_knowledgescope_one:n
\group_end:\kl_hide_end:
}
% \end{macrocode}
% In the following code, now the name of the instance is expanded before being written to the "kaux file".

\KAuxWriteX*{\exp_not:N\KAuxNewLinkScopetagInstance{#1}{\l_tmpb_tl}}
}
% \end{macrocode}
%
% \paragraph{Modified labels}
% \AP The boolean \csintro{\knowledge_configuration_label_autoscope_bool}
% activates or deactivates the automatic calling to \cs{knowlegescope} when \cs{\label} is used.
% \begin{macrocode}
\bool_new:N\knowledge_configuration_label_autoscope_bool
\bool_gset_true:N\knowledge_configuration_label_autoscope_bool
\KnowledgeConfigureBooleanOption[\knowledge_configuration_label_autoscope_bool]{patch~label}
\KnowledgeConfigureBooleanOption[\knowledge_configuration_label_autoscope_bool]{label~scope}
% \end{macrocode}
% One first changes the behavior of \cs\label\ in the preamble.
% \begin{macrocode}
\global\let\knowledge_label_before_loading_package:n\label
\cs_gset:Npn\label{

\bool_if:NTF
\knowledge_configuration_label_autoscope_bool
\knowledge_knowledgescope_one:n
\use_none:n
}
% \end{macrocode}
% \AP In order to circumvent this overloading, the normal \cs{\label} command
% can be used using \csintro{\knowledge_latex_label:n}:
% \begin{macrocode}
\cs_new:Npn\knowledge_latex_label:n{
\cs_if_exist:NTF\LaTeXlabel\LaTeXlabel\label
}
% \end{macrocode}
% \par\noindent\csintro{\knowledge_scopetag_warn_if_unknown:n} takes a "scopetag" as input.
% If it does not exist, it defines, and sets its boolean to false.
% \begin{macrocode}
\NewKAuxCommand\KAuxUndeclaredScopeTag{m}
{Package~scope:~States~that~a~labelname~is~used~in~a~knowledge~definition.}

% \subsection{Accessing knowledges}
%
% We define now the basic macros that are used for accessing knowledges.
% Each knowledge is identified by three parameters:
% \begin{itemize}

%
% \subsubsection{Generalities}
%
% The \cs{\knowledge} command is dealt in several steps.
% \begin{asparaitem}
% \item In a first phase, the "directives" are parsed using the keys \csintro{knowledge~directives}.
% During this phase, all the information concerning the target is fixed, as well as other pieces of informations
% such as the real reference of the "autoref" directive. The result is gathered in a second comma separated
% list of directives
% \item Then, depdnging on the targetting information, the
% \end{asparaitem}
% Essentially, the \cs{\keys_define:nn}\verb|{ knowledgenow~directives }|(...)
% commands used throughout the code are here to add new functionalities to it.
%
%
% \subsubsection{Defining directives}
%
%
% The commands used for introducing new directives.
% The command
% \begin{code}
% \csintro{\NewKnowledgeParamBool}[*]\{name\}\cs{\token}
% \end{code}
% creates a new boolean directive of name `name'.
% When the knowledge is executed, the value will be stored in the \cs{\token}.
% By default, the directive is only usable in \kl{knowledgenow directives}.
% If the optional star is used, then the \kl{directive} is usable in the \cs{\knowledge} command, and its value is propagated automatically. Hence, no-star means internal booleans used by the
% system, and star means booleans accessible to the user.

% \subsubsection{Scope basics}
%
%
% \kl{Knowledges} are attached to \kl{instances}, which identify
% the region in which these have been defined and also where they can be used.
% For instance, if the user mentions `\kl{scope=}section' when defining a knowledge,
% this means that the knowledge will only be visible in this
% area\footnote{Though it can be imported and become visible elsewhere using appropriate commands.}.
% Technically, instances are not directly handled by the user, nor by the "knowledge@@package" package.
%
% In this part of the code, we provide a small number of commands for dealing with instances.
% The real code that computes the current context of scope if later.
%
%
% \begin{compactdesc}

% instance to be used.

% of instances that are visible right now.
% \item[\csintro{\knowledge_scope_track_instance:Nn}\cs\tokenlist\{scope name\}]
% sets \cs{\tokenlist} to the innermost instance of the scope name.
% Typically, if the request is `\texttt{subsection}', the answer will be `\texttt{subsection-3.1}',
% identifying the subsection currently in scope.

% \subsubsection{Main \cs{\kl} code}
%
%
% The \cs{\kl}, and its internal version \cs{\klTKS} are the central ones in the package. Indeed, all commands such as \cs{\intro}, \cs{\phantomintro}, \cs{\reintro} or the \kl{"...@...@..."} notation eventually end to a call to these functions.
%\AP Essentially, \cs{\kl} parses its parameters, and then call its internal version \cs{\knowledge_klTKS:nnn}
% with proper parameters: Text, Knowledge, Scope (the scope can be empty):
%
% \AP The macro \csintro{\knowledge_kl:w} is the part of \cs{\kl}-like commands that parses the arguments, and then calls \cs{\knowledge_klTKS:nnn} with proper arguments.
% \begin{macrocode}
\NewDocumentCommand\knowledge_kl:w{d() o d() m}{

{\IfNoValueTF{#2}
{\knowledge_klTKS:nnn{#4}{#4}{#1}}
{\knowledge_klTKS:nnn{#4}{#2}{#1}}}
}
% \end{macrocode}
%
% \AP The following macro, \csintro{\knowledge_klTKS:nnn} is an internal version of \cs{\kl}-like commands.
% It takes explicitly (1) the text to be displayed,
% (2) the \kl{knowledge name} to be used for the search, and (3) a \kl{label} pointing to the \kl[instance]{instance of scope}
% in which the \kl{knowledge name} has to be searched for. This \kl{label} can be empty, and in this case, this means that
% the stack of instances that are visible in the context of the call of the command should be inspected for searching for
% the knowledge.
% \AP The macro \csintro{\klTKS} is a version of \cs{\knowledge_klTKS:nnn}
% that can be used without the "expl3@@package" syntax.

% \subsubsection{Variants of the \cs{\kl} macro}
%
%
%
% When defining a new use of \texttt{knowledge}, many macros have to be taken into account.
% Some have to be defined explicitly. Some other have default behaviours.
% \begin{asparaitem}
% \itemAP \csintro{\knowledge_kl_display_preprocess_tl} is the code to be used first before displaying. It does nothing for \cs{\kl}, but is set to \cs{\knowledge_kl_target_preprocess_tl} for \cs{\intro}, which performs the \cs{\label} command fir the introduction.
% \itemAP \csintro{\knowledge_kl_display_process_tl} is the code to be executed for displaying the \kl{knowledge}. This is not defined by default.
% \itemAP \csintro{\knowledge_kl_error_unknown:} The fallback code to execute when the \kl{knowledge} is unknown.
% By default, it displays a warning and put the name in orange.
% \itemAP \csintro{\knowledge_kl_update:N} is a code to be executed to update the knowledge. By default, it increments the ktuple counter `\cs{countuse_int}'.
% \itemAP \csintro{\knowledge_kl_namespace_tl} is the \kl{namespace} in which the \kl{knowledge} is to be searched. Not defined by default.
% \itemAP \csintro{\knowledge_kl_linkscope_tl} is a label that points to an instance of a \kl{scope}. It can be empty, and in this case, this means that the search proceeds in the \kl{stack of visible scope instances}. By default it is empty.
% \itemAP \csintro{\knowledge_kl_max_recursion_int} is the maximum number of recursion allowed when searching for a \kl{knowledge}. It is by default 40.
% \end{asparaitem}
%
% The codes can uses internally the following variables, that are accessible for the user when defining new \cs\kl-like commands:
% \begin{asparaitem}
% \itemAP \csintro{\knowledge_kl_command_tl} the command that has triggered the search
% \itemAP \csintro{\knowledge_kl_base_key_tl} contains the name of the knowledge for which the search has started,
% \itemAP \csintro{\knowledge_kl_text_tl} contains the text to be displayed,
% \itemAP \csintro{\knowledge_kl_key_tl} contains the name of the knowledge searched at a particular moment,
% \itemAP \csintro{\knowledge_kl_recursion_int} counts the number of indirection in the current, starting from \cs{\knowledge_kl_max_recursion_int}, and going down,
% \itemAP \csintro{\knowledge_kl_link_tl} contains the link to be followed.
% \itemAP \cs{\knowledge_kl_resourcetoken_tl} contains a single token, which is the location of the knowledge.
% \end{asparaitem}
%
% \begin{macrocode}
\let\nointro\phantomintro
% \end{macrocode}
%
% When the \cs{\intro} is used more than once, new labels are introduced (appending b,c,d\dots),
% in order to point to these targets easily.

%
% A bug occurs when hyperref is used in twocolumn mode and a link spreads on the boundary between two pages. This causes a fatal error. Here is defined a workaround found at:
%\url{http://tex.stackexchange.com/questions/249579/pdfendlink-ended-up-in-different-nesting-level-than-pdfstartlink-error-with}
% for avoiding problems with hyperref links being split it is suficient to call
% the macro \cs{\knowledgeFixHyperrefTwocolumn}
% or \cs\knowledgeconfigure\texttt\{\kl{fix hyperref twocolumn}\texttt\}
% \begin{macrocode}
