NAME
doctools::idx::export::wiki - wiki export plugin
SYNOPSIS
package require Tcl 8.4
package require doctools::idx::export::wiki ?0.2?
package require doctools::text
export serial configuration
______________________________________________________________________________
DESCRIPTION
This package implements the doctools keyword index export plugin for
the generation of wiki markup.
This is an internal package of doctools, for use by the higher level
management packages handling keyword indices, especially doc-
tools::idx::export, the export manager.
Using it from a regular interpreter is possible, however only with con-
tortions, and is not recommended. The proper way to use this function-
ality is through the package doctools::idx::export and the export man-
ager objects it provides.
API
The API provided by this package satisfies the specification of the do-
cidx export plugin API version 2.
export serial configuration
This command takes the canonical serialization of a keyword in-
dex, as specified in section Keyword index serialization format,
and contained in serial, the configuration, a dictionary, and
generates wiki markup encoding the index. The created string is
then returned as the result of the command.
WIKI MARKUP
The basic syntax of the wiki markup generated by this plugin are de-
scribed at http://wiki.tcl.tk/14.
The plugin goes beyond the classic markup to generate proper headers
and either a table or indented list of the keywords and their refer-
ences.
CONFIGURATION
The wiki export plugin recognizes the following configuration variables
and changes its behaviour as they specify.
dictionary map
This standard configuration variable contains a dictionary map-
ping from the symbolic files names in manpage references to the
actual filenames and/or urls to be used in the output.
Url references and symbolic file names without a mapping are
used unchanged.
enum style
This variable recognizes two values as legal, list (default),
and table. Depending on the value the plugin generates either a
list- or table-based wiki page for the index.
Note that this plugin ignores the standard configuration variables
user, file and format, and their values.
KEYWORD INDEX SERIALIZATION FORMAT
Here we specify the format used by the doctools v2 packages to serial-
ize keyword indices as immutable values for transport, comparison, etc.
We distinguish between regular and canonical serializations. While a
keyword index may have more than one regular serialization only exactly
one of them will be canonical.
regular serialization
[1] An index serialization is a nested Tcl dictionary.
[2] This dictionary holds a single key, doctools::idx, and
its value. This value holds the contents of the index.
[3] The contents of the index are a Tcl dictionary holding
the title of the index, a label, and the keywords and
references. The relevant keys and their values are
title The value is a string containing the title of the
index.
label The value is a string containing a label for the
index.
keywords
The value is a Tcl dictionary, using the keywords
known to the index as keys. The associated values
are lists containing the identifiers of the refer-
ences associated with that particular keyword.
Any reference identifier used in these lists has
to exist as a key in the references dictionary,
see the next item for its definition.
references
The value is a Tcl dictionary, using the identi-
fiers for the references known to the index as
keys. The associated values are 2-element lists
containing the type and label of the reference, in
this order.
Any key here has to be associated with at least
one keyword, i.e. occur in at least one of the
reference lists which are the values in the key-
words dictionary, see previous item for its defi-
nition.
[4] The type of a reference can be one of two values,
manpage
The identifier of the reference is interpreted as
symbolic file name, referring to one of the docu-
ments the index was made for.
url The identifier of the reference is interpreted as
an url, referring to some external location, like
a website, etc.
canonical serialization
The canonical serialization of a keyword index has the format as
specified in the previous item, and then additionally satisfies
the constraints below, which make it unique among all the possi-
ble serializations of the keyword index.
[1] The keys found in all the nested Tcl dictionaries are
sorted in ascending dictionary order, as generated by
Tcl's builtin command lsort -increasing -dict.
[2] The references listed for each keyword of the index, if
any, are listed in ascending dictionary order of their
labels, as generated by Tcl's builtin command lsort -in-
creasing -dict.
