DESCRIPTION

44       This  package  implements  the doctools table of contents import plugin
45       for the parsing of doctoc markup.
46
47       This is an internal package of doctools, for use by  the  higher  level
48       management  packages  handling  tables  of  contents,  especially  doc‐
49       tools::toc::import, the import manager.
50
51       Using it from a regular interpreter is possible, however only with con‐
52       tortions, and is not recommended.  The proper way to use this function‐
53       ality is through the package doctools::toc::import and the import  man‐
54       ager objects it provides.
55

API

57       The  API  provided  by  this package satisfies the specification of the
58       doctoc import plugin API version 2.
59
60       import string configuration
61              This command takes the string and parses it as doctoc markup en‐
62              coding a table of contents, in the context of the specified con‐
63              figuration (a dictionary). The result  of  the  command  is  the
64              canonical  serialization  of that table of contents, in the form
65              specified in section ToC serialization format.
66

[DOCTOC] NOTATION OF TABLES OF CONTENTS

68       The doctoc format for tables of contents, also called the doctoc markup
69       language, is too large to be covered in single section.  The interested
70       reader should start with the document
71
72       [1]    doctoc language introduction
73
74       and then proceed from there to the formal specifications, i.e. the doc‐
75       uments
76
77       [1]    doctoc language syntax and
78
79       [2]    doctoc language command reference.
80
81       to get a thorough understanding of the language.
82

TOC SERIALIZATION FORMAT

84       Here  we specify the format used by the doctools v2 packages to serial‐
85       ize tables of contents as immutable values for  transport,  comparison,
86       etc.
87
88       We  distinguish  between regular and canonical serializations.  While a
89       table of contents may have more than one regular serialization only ex‐
90       actly one of them will be canonical.
91
92       regular serialization
93
94              [1]    The  serialization  of  any table of contents is a nested
95                     Tcl dictionary.
96
97              [2]    This dictionary holds a single  key,  doctools::toc,  and
98                     its  value. This value holds the contents of the table of
99                     contents.
100
101              [3]    The contents of the table of contents are a  Tcl  dictio‐
102                     nary holding the title of the table of contents, a label,
103                     and its elements. The relevant keys and their values are
104
105                     title  The value is a string containing the title of  the
106                            table of contents.
107
108                     label  The  value  is a string containing a label for the
109                            table of contents.
110
111                     items  The value is a Tcl list holding  the  elements  of
112                            the table, in the order they are to be shown.
113
114                            Each element is a Tcl list holding the type of the
115                            item, and its description, in this order.  An  al‐
116                            ternative  description  would  be that it is a Tcl
117                            dictionary holding a single key,  the  item  type,
118                            mapped to the item description.
119
120                            The  two  legal  item types and their descriptions
121                            are
122
123                            reference
124                                   This item describes a single entry  in  the
125                                   table  of  contents,  referencing  a single
126                                   document.  To this end its value is  a  Tcl
127                                   dictionary  containing an id for the refer‐
128                                   enced document, a label, and a longer  tex‐
129                                   tual  description  which  can be associated
130                                   with the  entry.   The  relevant  keys  and
131                                   their values are
132
133                                   id     The value is a string containing the
134                                          id of the document  associated  with
135                                          the entry.
136
137                                   label  The  value  is a string containing a
138                                          label for this  entry.  This  string
139                                          also  identifies  the  entry, and no
140                                          two entries  (references  and  divi‐
141                                          sions)  in  the  containing list are
142                                          allowed to have the same label.
143
144                                   desc   The value is a string  containing  a
145                                          longer description for this entry.
146
147                            division
148                                   This  item  describes a group of entries in
149                                   the table of contents, inducing a hierarchy
150                                   of entries.  To this end its value is a Tcl
151                                   dictionary  containing  a  label  for   the
152                                   group, an optional id to a document for the
153                                   whole group, and the list of entries in the
154                                   group.   The relevant keys and their values
155                                   are
156
157                                   id     The value is a string containing the
158                                          id  of  the document associated with
159                                          the whole group.  This  key  is  op‐
160                                          tional.
161
162                                   label  The  value  is a string containing a
163                                          label for  the  group.  This  string
164                                          also  identifies  the  entry, and no
165                                          two entries  (references  and  divi‐
166                                          sions)  in  the  containing list are
167                                          allowed to have the same label.
168
169                                   items  The value is a Tcl list holding  the
170                                          elements  of the group, in the order
171                                          they are to be shown.  This list has
172                                          the  same structure as the value for
173                                          the keyword items used  to  describe
174                                          the  whole  table  of  contents, see
175                                          above.  This  closes  the  recusrive
176                                          definition  of  the  structure, with
177                                          divisions holding the same  type  of
178                                          elements  as the whole table of con‐
179                                          tents, including other divisions.
180
181       canonical serialization
182              The canonical serialization of a table of contents has the  for‐
183              mat  as  specified  in  the previous item, and then additionally
184              satisfies the constraints below, which make it unique among  all
185              the possible serializations of this table of contents.
186
187              [1]    The  keys  found  in  all the nested Tcl dictionaries are
188                     sorted in ascending dictionary  order,  as  generated  by
189                     Tcl's builtin command lsort -increasing -dict.
