5.5.4 Dico Scheme Primitives

GNU Dico provides the following Scheme primitives for accessing various fields of the strat and key arguments to match callback:

Function: dico-key? obj ¶

Return ‘#t’ if obj is a Dico key object.

Function: dico-key->word key ¶

Extract the lookup word from the key object key.

Function: dico-make-key strat word ¶

Create new key object from strategy strat and word word.

Function: dico-strat-selector? strat ¶

Return true if strat has a selector (see Strategy Selectors).

Function: dico-strat-select? strat word key ¶

Return true if key matches word as per strategy selector strat. The key is a ‘Dico Key’ object.

Function: dico-strat-name strat ¶

Return the name of strategy strat.

Function: dico-strat-description strat ¶

Return a textual description of the strategy strat.

Function: dico-strat-default? strat ¶

Return true if strat is a default strategy. See default strategy.

Function: dico-register-strat strat descr [fun] ¶

Register a new strategy. If fun is given it will be used as a callback for that strategy. Notice, that you can use strategies implemented in Guile in your C code as well (see strategy).

The selector function must be declared as follows:

(define (fun key word)
  ...)

It must return #t if key matches word, and #f otherwise.
