doctools::idx::export::wiki(n) 0.2 tcllib "Documentation tools"
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
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.
Keyword index serialization format
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
An index serialization is a nested Tcl dictionary.
This dictionary holds a single key, doctools::idx, and its value. This value holds the contents of the index.
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.
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.
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.
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.
