130 This document specifies both names and syntax of all the commands which
131 together are the doctools markup language, version 1. As this document
132 is intended to be a reference the commands are listed in alphabetical
133 order, and the descriptions are relatively short. A beginner should
134 read the much more informally written doctools language introduction
135 first.
136
138 arg text
139 Text markup. The argument text is marked up as the argument of a
140 command. Main uses are the highlighting of command arguments in
141 free-form text, and for the argument parameters of the markup
142 commands call and usage.
143 arg_def type name ?mode?
145 Text structure. List element. Argument list. Automatically
146 closes the previous list element. Specifies the data-type of the
147 described argument of a command, its name and its i/o-mode. The
148 latter is optional.
149 bullet Deprecated. Text structure. List element. Itemized list. See
151 item for the canonical command to open a list item in an item‐
152 ized list.
153 call args
155 Text structure. List element. Definition list. Automatically
156 closes the previous list element. Defines the term as a command
157 and its arguments. The first argument is the name of the com‐
158 mand described by the following free-form text, and all argu‐
159 ments coming after that are descriptions of the command's argu‐
160 ments. It is expected that the arguments are marked up with
161 arg, method, option etc., as is appropriate, and that the com‐
162 mand itself is marked up with cmd. It is expected that the for‐
163 matted term is not only printed in place, but also in the table
164 of contents of the document, or synopsis, depending on the out‐
165 put format.
166 category text
168 Document information. Anywhere. This command registers its plain
169 text arguments as the category this document belongs to. If this
170 command is used multiple times the last value specified is used.
171 class text
173 Text markup. The argument is marked up as the name of a class.
174 The text may have other markup already applied to it. Main use
175 is the highlighting of class names in free-form text.
176 cmd text
178 Text markup. The argument text is marked up as the name of a Tcl
179 command. The text may have other markup already applied to it.
180 Main uses are the highlighting of commands in free-form text,
181 and for the command parameters of the markup commands call and
182 usage.
183 cmd_def command
185 Text structure. List element. Command list. Automatically closes
186 the previous list element. The argument specifies the name of
187 the Tcl command to be described by the list element. Expected to
188 be marked up in the output as if it had been formatted with cmd.
189 comment plaintext
191 Text markup. The argument text is marked up as a comment stand‐
192 ing outside of the actual text of the document. Main use is in
193 free-form text.
194 const text
196 Text markup. The argument is marked up as a constant value. The
197 text may have other markup already applied to it. Main use is
198 the highlighting of constants in free-form text.
199 copyright text
201 Document information. Anywhere. The command registers the plain
202 text argument as a copyright assignment for the manpage. When
203 invoked more than once the assignments are accumulated.
204 def text
206 Text structure. List element. Definition list. Automatically
207 closes the previous list element. The argument text is the term
208 defined by the new list element. Text markup can be applied to
209 it.

213 document body. Implicitly starts a section named "DESCRIPTION"
214 (See command section).
215 enum Text structure. List element. Enumerated list. Automatically
217 closes the previous list element.
218 emph text

221 use is for general highlighting of pieces of free-form text
222 without attaching special meaning to the pieces.
223 example text
225 Text structure, Text markup. This command marks its argument up
226 as an example. Main use is the simple embedding of examples in
227 free-form text. It should be used if the example does not need
228 special markup of its own. Otherwise use a sequence of exam‐
229 ple_begin ... example_end.
230 example_begin
232 Text structure. This commands starts an example. All text until
233 the next example_end belongs to the example. Line breaks, spa‐
234 ces, and tabs have to be preserved literally. Examples cannot be
235 nested.
236 example_end
238 Text structure. This command closes the example started by the
239 last example_begin.
240 file text
242 Text markup. The argument is marked up as a file or directory,
243 i.e. in general a path. The text may have other markup already
244 applied to it. Main use is the highlighting of paths in free-
245 form text.

256 be interpreted the human-readable description of the image, and
257 put into the output in a suitable position, if such is supported
258 by the format. The HTML format, for example, can place it into
259 the alt attribute of image references.
260 include filename
262 Templating. The contents of the named file are interpreted as
263 text written in the doctools markup and processed in the place
264 of the include command. The markup in the file has to be self-
265 contained. It is not possible for a markup command to cross the
266 file boundaries.
267 item Text structure. List element. Itemized list. Automatically
269 closes the previous list element.
270 keywords args
272 Document information. Anywhere. This command registers all its
273 plain text arguments as keywords applying to this document. Each
274 argument is a single keyword. If this command is used multiple
275 times all the arguments accumulate.

278 form text. Required to avoid interpretation of a left bracket
279 as the start of a markup command.

283 the list is determined by the argument what of the command. This
284 further determines which commands are have to be used to start
285 the list elements. Lists can be nested, i.e. it is allowed to
286 start a new list within a list element.
287 The allowed types (and their associated item commands) are:
289 arguments
291 arg_def.
292 commands
294 cmd_def.

297 def and call.
298 enumerated
300 enum
301 itemized
303 item
304 options
306 opt_def
307 tkoptions
309 tkoption_def
310 Additionally the following names are recognized as shortcuts for some
312 of the regular types:
313 args Short for arguments.
315 cmds Short for commands.
317 enum Short for enumerated.
319 item Short for itemized.
321 opts Short for options.
323 At last the following names are still recognized for backward compati‐
325 bility, but are otherwise considered to be deprecated.
326 arg Deprecated. See arguments.
328 bullet Deprecated. See itemized.
330 cmd Deprecated. See commands.

360 Text markup. The argument text is marked up as the name of an
361 object method, i.e. subcommand of a Tcl command. The text may
362 have other markup already applied to it. Main uses are the high‐
363 lighting of method names in free-form text, and for the command
364 parameters of the markup commands call and usage.

401 graphs. Each command closes the paragraph coming before it and

403 level forms of structure are sections and subsections.

431 to format is needed.
