NAME
       doctoc_lang_syntax - doctoc language syntax

DESCRIPTION
       This  document contains the formal specification of the syntax of the doctoc markup language, version
       1.1 in Backus-Naur-Form. This document is intended to be a reference, complementing the  doctoc  lan-guage language
       guage  command  reference.   A  beginner should read the much more informally written doctoc language
       introduction first before trying to understand either this document or the command reference.

FUNDAMENTALS
       In the broadest terms possible the doctoc markup language is like SGML and similar languages. A docu-ment document
       ment  written  in  this language consists primarily of markup commands, with text embedded into it at
       some places.

       Each markup command is a just Tcl command surrounded by a matching pair of [ and  ].  Which  commands
       are  available,  and  their arguments, i.e. syntax is specified in the doctoc language command refer-ence. reference.
       ence.

       In this document we specify first the lexeme, and then the syntax, i.e.  how  we  can  mix  text  and
       markup commands with each other.

LEXICAL DEFINITIONS
       In the syntax rules listed in the next section

       [1]    <TEXT> stands for all text except markup commands.

       [2]    Any  XXX stands for the markup command [xxx] including its arguments. Each markup command is a
              Tcl command surrounded by a matching pair of [ and ]. Inside of  these  delimiters  the  usual
              rules  for  a  Tcl  command apply with regard to word quotation, nested commands, continuation
              lines, etc.

       [3]    <WHITE> stands for all text consisting only of spaces, newlines, tabulators  and  the  comment
              markup command.


SYNTAX
       The  rules listed here specify only the syntax of doctoc documents. The lexical level of the language
       was covered in the previous section.

       Regarding the syntax of the (E)BNF itself

       [1]    The construct { X } stands for zero or more occurrences of X.

       [2]    The construct [ X ] stands for zero or one occurrence of X.

       The syntax:

       toc       = defs
                   TOC_BEGIN
                   contents
                   TOC_END
                   { <WHITE> }

       defs      = { INCLUDE | VSET | <WHITE> }
       contents  = { defs entry } [ defs ]

       entry     = ITEM | division

       division  = DIVISION_START
                   contents
                   DIVISION_END
