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.



  

  
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.



  

  
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.

  

  

  
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.



  

  







  
[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







  

  
The value is a string containing the title of the index.

  

  
The value is a string containing a label for the index.

  

  
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.

  

  

  
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,







  

  
The identifier of the reference is interpreted as symbolic file name,
      referring to one of the documents the index was made for.

  

  
The identifier of the reference is interpreted as an url, referring to
      some external location, like a website, etc.









  

  
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.
