DESCRIPTION

       This package implements the doctools table of contents export plugin for the generation of
       wiki markup.

       This is an internal package of doctools, for use by the higher level  management  packages
       handling tables of contents, especially doctools::toc::export, the export manager.

       Using it from a regular interpreter is possible, however only with contortions, and is not
       recommended.   The  proper  way  to  use  this  functionality  is  through   the   package
       doctools::toc::export and the export manager objects it provides.

API

       The  API  provided by this package satisfies the specification of the doctoc export plugin
       API version 2.

       export serial configuration
              This command takes the canonical serialization of a table of contents, as specified
              in  section ToC serialization format, and contained in serial, the configuration, a
              dictionary, and generates wiki markup encoding the table.  The  created  string  is
              then returned as the result of the command.

WIKI MARKUP

       The  basic  syntax  of  the  wiki  markup  generated  by  this  plugin  are  described  at
       http://wiki.tcl.tk/14.

       The plugin goes beyond the classic markup to generate proper headers and indenting.

CONFIGURATION

       The wiki export plugin recognizes the following configuration variables  and  changes  its
       behaviour as they specify.

       dictionary map
              This  standard  configuration  variable  contains  a  dictionary  mapping  from the
              (symbolic) document ids in reference entries to the actual filenames and/or urls to
              be used in the output.

              Document ids without a mapping are used unchanged.

       Note  that this plugin ignores the standard configuration variables user, file and format,
       and their values.

TOC SERIALIZATION FORMAT

       Here we specify the format used by  the  doctools  v2  packages  to  serialize  tables  of
       contents as immutable values for transport, comparison, etc.

       We  distinguish  between  regular and canonical serializations.  While a table of contents
       may have more than one regular serialization only exactly one of them will be canonical.

       regular serialization

              [1]    The serialization of any table of contents is a nested Tcl dictionary.

              [2]    This dictionary holds a single key, doctools::toc, and its value. This value
                     holds the contents of the table of contents.

              [3]    The contents of the table of contents are a Tcl dictionary holding the title
                     of the table of contents, a label, and its elements. The relevant  keys  and
                     their values are

                     title  The value is a string containing the title of the table of contents.

                     label  The value is a string containing a label for the table of contents.

                     items  The  value  is  a  Tcl list holding the elements of the table, in the
                            order they are to be shown.

                            Each element is a Tcl list holding the type  of  the  item,  and  its
                            description,  in this order. An alternative description would be that
                            it is a Tcl dictionary holding a single key, the item type, mapped to
                            the item description.

                            The two legal item types and their descriptions are

                            reference
                                   This  item  describes a single entry in the table of contents,
                                   referencing a single document.  To this end its value is a Tcl
                                   dictionary  containing  an  id  for the referenced document, a
                                   label,  and  a  longer  textual  description  which   can   be
                                   associated with the entry.  The relevant keys and their values
                                   are

                                   id     The value is a string containing the id of the document
                                          associated with the entry.

                                   label  The  value  is  a  string  containing  a label for this
                                          entry. This string also identifies the  entry,  and  no
                                          two   entries   (references   and   divisions)  in  the
                                          containing list are allowed to have the same label.

                                   desc   The value is a string containing a  longer  description
                                          for this entry.

                            division
                                   This  item  describes  a  group  of  entries  in  the table of
                                   contents, inducing a hierarchy of entries.  To  this  end  its
                                   value is a Tcl dictionary containing a label for the group, an
                                   optional id to a document for the whole group, and the list of
                                   entries in the group.  The relevant keys and their values are

                                   id     The value is a string containing the id of the document
                                          associated with the whole group. This key is optional.

                                   label  The value is a string containing a label for the group.
                                          This  string  also  identifies  the  entry,  and no two
                                          entries (references and divisions)  in  the  containing
                                          list are allowed to have the same label.

                                   items  The  value  is  a  Tcl list holding the elements of the
                                          group, in the order they are to be  shown.   This  list
                                          has  the  same  structure  as the value for the keyword
                                          items used to describe the whole table of contents, see
                                          above.  This  closes  the  recusrive  definition of the
                                          structure, with divisions  holding  the  same  type  of
                                          elements  as  the  whole  table  of contents, including
                                          other divisions.

       canonical serialization
              The canonical serialization of a table of contents has the format as  specified  in
              the  previous  item,  and  then additionally satisfies the constraints below, which
              make it unique among all the possible serializations of this table of contents.

              [1]    The keys found in all the nested Tcl dictionaries are  sorted  in  ascending
                     dictionary  order,  as  generated by Tcl's builtin command lsort -increasing
                     -dict.
