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
doctools::idx::export,
the export manager.
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
doctools::idx::export and the export manager objects it
provides.
API¶
The API provided by this package satisfies the specification of the docidx
export plugin API version 2.
- export serial configuration
- This command takes the canonical serialization of a keyword index, 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 described 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 references.
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 mapping 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.
Here we specify the format used by the doctools v2 packages to serialize 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
references 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 identifiers 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
keywords dictionary, see previous item for its definition.
- [4]
- The type of a reference can be one of two values,
- manpage
- The identifier of the reference is interpreted as symbolic file name,
refering to one of the documents the index was made for.
- url
- The identifier of the reference is interpreted as an url, refering 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 possible 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 -increasing -dict.
