.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.SH NAME
doctools::toc::export::wiki \- wiki export plugin
.SH SYNOPSIS
package require \fBTcl 8\&.5 9\fR
.sp
package require \fBdoctools::toc::export::wiki ?0\&.2?\fR
.sp
package require \fBdoctools::text\fR
.sp
\fBexport\fR \fIserial\fR \fIconfiguration\fR
.sp
.BE
.SH DESCRIPTION
This package implements the doctools table of contents export plugin
for the generation of wiki markup\&.
.PP
This is an internal package of doctools, for use by the higher level
management packages handling tables of contents, especially \fBdoctools::toc::export\fR, the export manager\&.
.PP
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
\fBdoctools::toc::export\fR and the export manager objects it
provides\&.
.SH API
The API provided by this package satisfies the specification of the
doctoc export plugin API version 2\&.
.TP
\fBexport\fR \fIserial\fR \fIconfiguration\fR
This command takes the canonical serialization of a table of contents,
as specified in section \fBToC serialization format\fR, and
contained in \fIserial\fR, the \fIconfiguration\fR, a dictionary, and
generates wiki markup encoding the table\&.
The created string is then returned as the result of the command\&.
.PP
.SH "WIKI MARKUP"
The basic syntax of the wiki markup generated by this plugin are
described at \fIhttp://wiki\&.tcl\&.tk/14\fR\&.
.PP
The plugin goes beyond the classic markup to generate proper headers
and indenting\&.
.SH CONFIGURATION
The wiki export plugin recognizes the following configuration
variables and changes its behaviour as they specify\&.
.TP
dictionary \fImap\fR
This standard configuration variable contains a dictionary mapping
from the (symbolic) document ids in reference entries to the actual
filenames and/or urls to be used in the output\&.
.sp
Document ids without a mapping are used unchanged\&.
.PP
\fINote\fR that this plugin ignores the standard configuration
variables \fBuser\fR, \fBfile\fR and \fBformat\fR, and their values\&.
.SH "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\&.
.PP
We distinguish between \fIregular\fR and \fIcanonical\fR
serializations\&.
While a table of contents may have more than one regular serialization
only exactly one of them will be \fIcanonical\fR\&.
.PP
.TP
regular serialization
.RS
.IP [1]
The serialization of any table of contents is a nested Tcl dictionary\&.
.IP [2]
This dictionary holds a single key, \fBdoctools::toc\fR, and its
value\&. This value holds the contents of the table of contents\&.
.IP [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
.RS
.TP
\fBtitle\fR
The value is a string containing the title of the table of contents\&.
.TP
\fBlabel\fR
The value is a string containing a label for the table of contents\&.
.TP
\fBitems\fR
The value is a Tcl list holding the elements of the table, in the
order they are to be shown\&.
.sp
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\&.
.sp
The two legal item types and their descriptions are
.RS
.TP
\fBreference\fR
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
.RS
.TP
\fBid\fR
The value is a string containing the id of the document associated
with the entry\&.
.TP
\fBlabel\fR
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\&.
.TP
\fBdesc\fR
The value is a string containing a longer description for this entry\&.
.RE
.TP
\fBdivision\fR
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
.RS
.TP
\fBid\fR
The value is a string containing the id of the document associated
with the whole group\&. This key is optional\&.
.TP
\fBlabel\fR
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\&.
.TP
\fBitems\fR
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
\fBitems\fR 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\&.
.RE
.RE
.RE
.RE
.TP
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\&.
.RS
.IP [1]
The keys found in all the nested Tcl dictionaries are sorted in
ascending dictionary order, as generated by Tcl's builtin command
\fBlsort -increasing -dict\fR\&.
.RE
.PP
.SH "BUGS, IDEAS, FEEDBACK"
This document, and the package it describes, will undoubtedly contain
bugs and other problems\&.
Please report such in the category \fIdoctools\fR of the
\fITcllib Trackers\fR [http://core\&.tcl\&.tk/tcllib/reportlist]\&.
Please also report any ideas for enhancements you may have for either
package and/or documentation\&.
.PP
When proposing code changes, please provide \fIunified diffs\fR,
i\&.e the output of \fBdiff -u\fR\&.
.PP
Note further that \fIattachments\fR are strongly preferred over
inlined patches\&. Attachments can be made by going to the \fBEdit\fR
form of the ticket immediately after its creation, and then using the
left-most button in the secondary navigation bar\&.
