Jan Mas Rovira	8daca2ba0a	New fixity/iterator syntax (#2332) ... - Closes #2330 - Closes #2329 This pr implements the syntax changes described in #2330. It drops support for the old yaml-based syntax. Some valid examples: ``` syntax iterator for {init := 1; range := 1}; syntax fixity cons := binary {assoc := right}; syntax fixity cmp := binary; syntax fixity cmp := binary {}; -- debatable whether we want to accept empty {} or not. I think we should ``` # Future work This pr creates an asymmetry between iterators and operators definitions. Iterators definition do not require a constructor. We could add it to make it homogeneous, but it looks a bit redundant: ``` syntax iterator for := mkIterator {init := 1; range := 1}; ``` We could consider merging iterator and fixity declarations with this alternative syntax. ``` syntax XXX for := iterator {init := 1; range := 1}; syntax XXX cons := binary {assoc := right}; ``` where `XXX` is a common keyword.

Łukasz Czajka	eebe961321	User-friendly operator declaration syntax (#2270) ... * Closes #1964 Adds the possibility to define operator fixities. They live in a separate namespace. Standard library defines a few in `Stdlib.Data.Fixity`: ``` syntax fixity rapp {arity: binary, assoc: right}; syntax fixity lapp {arity: binary, assoc: left, same: rapp}; syntax fixity seq {arity: binary, assoc: left, above: [lapp]}; syntax fixity functor {arity: binary, assoc: right}; syntax fixity logical {arity: binary, assoc: right, above: [seq]}; syntax fixity comparison {arity: binary, assoc: none, above: [logical]}; syntax fixity pair {arity: binary, assoc: right}; syntax fixity cons {arity: binary, assoc: right, above: [pair]}; syntax fixity step {arity: binary, assoc: right}; syntax fixity range {arity: binary, assoc: right, above: [step]}; syntax fixity additive {arity: binary, assoc: left, above: [comparison, range, cons]}; syntax fixity multiplicative {arity: binary, assoc: left, above: [additive]}; syntax fixity composition {arity: binary, assoc: right, above: [multiplicative]}; ``` The fixities are identifiers in a separate namespace (different from symbol and module namespaces). They can be exported/imported and then used in operator declarations: ``` import Stdlib.Data.Fixity open; syntax operator && logical; syntax operator || logical; syntax operator + additive; syntax operator * multiplicative; ```	2023-08-09 18:15:51 +02:00
