DESCRIPTION
This package implements the doctools table of contents import plugin for the parsing of doctoc
markup.
This is an internal package of doctools, for use by the higher level management packages handling
tables of contents, especially doctools::toc::import, the import manager.
Using it from a regular interpreter is possible, however only with contortions, and is not recom-mended. recommended.
mended. The proper way to use this functionality is through the package doctools::toc::import and
the import manager objects it provides.
API
The API provided by this package satisfies the specification of the doctoc import plugin API version
2.
import string configuration
This command takes the string and parses it as doctoc markup encoding a table of contents, in
the context of the specified configuration (a dictionary). The result of the command is the
canonical serialization of that table of contents, in the form specified in section ToC seri-alization serialization
alization format.
[DOCTOC] NOTATION OF TABLES OF CONTENTS
The doctoc format for tables of contents, also called the doctoc markup language, is too large to be
covered in single section. The interested reader should start with the document
[1] doctoc language introduction
and then proceed from there to the formal specifications, i.e. the documents
[1] doctoc language syntax and
[2] doctoc language command reference.
to get a thorough understanding of the language.
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 ta-ble table
ble 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 descrip-tion description
tion 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 con-taining containing
taining 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.
