.\" 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
docidx_intro \- docidx introduction
.SH DESCRIPTION
.PP
\fIdocidx\fR (short for \fIdocumentation tables of contents\fR)
stands for a set of related, yet different, entities which are working
together for the easy creation and transformation of keyword-based
indices for documentation\&. These are
.IP [1]
A tcl based language for the semantic markup of a keyword index\&.
Markup is represented by Tcl commands\&.
.IP [2]
A package providing the ability to read and transform texts written in
that markup language\&. It is important to note that the actual
transformation of the input text is delegated to plugins\&.
.IP [3]
An API describing the interface between the package above and a
plugin\&.
.PP
.PP
Which of the more detailed documents are relevant to the reader of
this introduction depends on their role in the documentation process\&.
.PP
.IP [1]
A \fIwriter\fR of documentation has to understand the markup language
itself\&. A beginner to docidx should read the more informally written
\fIdocidx language introduction\fR first\&. Having digested this
the formal \fIdocidx language syntax\fR specification should
become understandable\&. A writer experienced with docidx may only
need the \fIdocidx language command reference\fR from time to
time to refresh her memory\&.
.sp
While a document is written the \fBdtp\fR application can be used
to validate it, and after completion it also performs the conversion
into the chosen system of visual markup, be it *roff, HTML, plain
text, wiki, etc\&. The simpler \fBdtplite\fR application makes
internal use of docidx when handling directories of documentation,
automatically generating a proper keyword index for them\&.
.IP [2]
A \fIprocessor\fR of documentation written in the \fIdocidx\fR
markup language has to know which tools are available for use\&.
.sp
The main tool is the aforementioned \fBdtp\fR application provided
by Tcllib\&. The simpler \fBdtplite\fR does not expose docidx to the
user\&.
At the bottom level, common to both applications, however sits the
package \fBdoctoools::idx\fR, providing the basic facilities to
read and process files containing text in the docidx format\&.
.IP [3]
At last, but not least, \fIplugin writers\fR have to understand the
interaction between the \fBdoctools::idx\fR package and its
plugins, as described in the \fIdocidx plugin API reference\fR\&.
.PP
.SH "RELATED FORMATS"
docidx does not stand alone, it has two companion formats\&. These are
called \fIdoctoc\fR and \fIdoctools\fR, and they are for the markup
of \fItables of contents\fR, and general documentation,
respectively\&.
They are described in their own sets of documents, starting at the
\fIdoctoc introduction\fR and the \fIdoctools introduction\fR,
respectively\&.
.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\&.
