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 recommended. 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 serialization 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.
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.
