16 synopsis: Basic symantics combinators for Embedded Domain-Specific Languages (EDSL)
18 This is a work-in-progress collection of basic tagless-final combinators,
19 along with some advanced utilities to exploit them.
22 gathers commonly used tagless-final combinators
23 (the syntax part of symantics).
24 * @Symantic.Data@ is an interpreter enabling to pattern-match on combinators,
25 while keeping their extensibility.
27 enables to give a default value to combinators which avoids boilerplate code
28 when implementing combinators for an interpreter is factorizable.
29 * @Symantic.ObserveSharing@
30 enables to observe Haskell @let@ definitions,
31 turning infinite values into finite ones,
32 which is useful to inspect and optimize recursive grammars for example.
33 Inspired by Andy Gill's [Type-safe observable sharing in Haskell](https://doi.org/10.1145/1596638.1596653).
34 For an example, see [symantic-parser](https://hackage.haskell.org/package/symantic-parser).
36 enables the lifting to any interpreter
37 of any Haskell functions taking as arguments
38 only polymorphic types (possibly constrained)
39 or functions using such types.
40 Inspired by Oleg Kiselyov's [TDPE.hs](http://okmij.org/ftp/tagless-final/course/TDPE.hs).
42 is an interpreter enabling to turn combinators into a human-readable string.
44 enables to derive reciprocal functions between
45 data-constructors and @Either@s of tuples.
47 gathers utilities for currying or uncurrying tuples
48 of size greater or equal to 2.
50 gathers utilities for parsing or viewing
51 infix, prefix and postfix combinators.
