This document specifies both names and syntax of all the commands
which together are the doctools markup language, version 1. As this document
is intended to be a reference the commands are listed in alphabetical order,
and the descriptions are relatively short. A beginner should read the much
more informally written doctools language introduction first.
- arg text
- Text markup. The argument text is marked up as the argument of a
command. Main uses are the highlighting of command arguments in free-form
text, and for the argument parameters of the markup commands call
and usage.
- arg_def
type name ?mode?
- Text structure. List element. Argument list. Automatically closes the
previous list element. Specifies the data-type of the described
argument of a command, its name and its i/o-mode. The latter
is optional.
- bullet
- Deprecated. Text structure. List element. Itemized list. See
item for the canonical command to open a list item in an itemized
list.
- call
args
- Text structure. List element. Definition list. Automatically closes the
previous list element. Defines the term as a command and its arguments.
The first argument is the name of the command described by the following
free-form text, and all arguments coming after that are descriptions of
the command's arguments. It is expected that the arguments are marked up
with arg, method, option etc., as is appropriate, and
that the command itself is marked up with cmd. It is expected that
the formatted term is not only printed in place, but also in the table of
contents of the document, or synopsis, depending on the output
format.
- category
text
- Document information. Anywhere. This command registers its plain text
arguments as the category this document belongs to. If this command is
used multiple times the last value specified is used.
- class
text
- Text markup. The argument is marked up as the name of a class. The
text may have other markup already applied to it. Main use is the
highlighting of class names in free-form text.
- cmd text
- Text markup. The argument text is marked up as the name of a Tcl
command. The text may have other markup already applied to it. Main
uses are the highlighting of commands in free-form text, and for the
command parameters of the markup commands call and
usage.
- cmd_def
command
- Text structure. List element. Command list. Automatically closes the
previous list element. The argument specifies the name of the Tcl
command to be described by the list element. Expected to be marked up
in the output as if it had been formatted with cmd.
- Text markup. The argument text is marked up as a comment standing outside
of the actual text of the document. Main use is in free-form text.
- const
text
- Text markup. The argument is marked up as a constant value. The
text may have other markup already applied to it. Main use is the
highlighting of constants in free-form text.

- Document information. Anywhere. The command registers the plain text
argument as a copyright assignment for the manpage. When invoked more than
once the assignments are accumulated.
- def text
- Text structure. List element. Definition list. Automatically closes the
previous list element. The argument text is the term defined by the new
list element. Text markup can be applied to it.
- description
- Document structure. This command separates the header from the document
body. Implicitly starts a section named "DESCRIPTION" (See
command section).
- enum
- Text structure. List element. Enumerated list. Automatically closes the
previous list element.
- emph
text
- Text markup. The argument text is marked up as emphasized. Main use is for
general highlighting of pieces of free-form text without attaching special
meaning to the pieces.
- example
text
- Text structure, Text markup. This command marks its argument up as an
example. Main use is the simple embedding of examples in free-form
text. It should be used if the example does not need special markup
of its own. Otherwise use a sequence of example_begin ...
example_end.
- example_begin
- Text structure. This commands starts an example. All text until the next
example_end belongs to the example. Line breaks, spaces, and tabs

The text may have other markup already applied to it. Main use is the
highlighting of function names in free-form text.
- image name
?label?
- Text markup. The argument is the symbolic name of an image and
replaced with the image itself, if a suitable variant is found by the
backend. The second argument, should it be present, will be interpreted
the human-readable description of the image, and put into the output in a
suitable position, if such is supported by the format. The HTML format,
for example, can place it into the alt attribute of image
references.
- include
filename
- Templating. The contents of the named file are interpreted as text written
in the doctools markup and processed in the place of the include command.
The markup in the file has to be self-contained. It is not possible for a
markup command to cross the file boundaries.
- item
- Text structure. List element. Itemized list. Automatically closes the
previous list element.
- keywords

Required to avoid interpretation of a left bracket as the start of a
markup command.
- list_begin
what
- Text structure. This command starts a list. The exact nature of the list
is determined by the argument what of the command. This further
determines which commands are have to be used to start the list elements.
Lists can be nested, i.e. it is allowed to start a new list within a list
element.
The allowed types (and their associated item commands)
are:

some of the regular types:
