doctools::toc::export::doctoc - doctoc export plugin

Table Of Contents


package require Tcl 8.5 9
package require doctools::toc::export::doctoc ?0.2.2?

export serial configuration


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


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

[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.


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

Note that this plugin ignores the standard configuration variables format, and map, 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.

Bugs, Ideas, Feedback
