9 Library gathering main ideas from the
10 <http://okmij.org/ftp/tagless-final/ Tagless-Final>
11 approach of embedded DSL (Domain-Specific Language)
12 developed by Jacques Carette, Oleg Kiselyov and Chung-chieh Shan,
13 and pursuing their work to make it usable as a non-embedded DSL.
15 A so-called /symantic/ type class defines a /syntax/
16 and each of its instances defines a new /semantic/
17 (computing a Haskell term, serializing, optimizing, …).
19 Combining the methods of those /symantic/ type classes
20 gives rise to a DSL within which one can
21 write /symantic/ expressions at developing time;
22 but in order to handle such expression when entered by an end-user,
23 one has to be able to construct it at runtime.
25 This library (including its Test.hs files) demonstrates this
26 for a few usual types and methods, by:
28 * Parsing a /symantic/ expression
29 from an AST (Abstract Syntax Tree).
31 * Removing or adding /symantic/ parsers
32 by fully reusing old parsers
33 (i.e. without copying or altering them).
35 * Interpreting a /symantic/ expression
36 multiple times and with different interpreters
37 without reparsing the expression.
39 Hence, one can select all or a few expressions (and associated types)
40 of this library, add its own, parse them at runtime from its own AST,
41 and then interpret them at will.
43 One important drawback of this flexibility
44 is the introduction of a lot of type constraints;
45 those may be more readable directly in the source code
46 than in its Haddock rendition.
48 Your comments, problem reports, or questions are very welcome! :-)
