Refactoring of Ligodity (CameLIGO) and making an AST pretty-printer - AST.ml/AST.mli: - The AST now distinguishes the constructors `None` and `Some` as being predefined, as in PascaLIGO. See type `AST.constr_pattern`. - I removed the nodes specific to Liquidity, e.g. `let%entry`, and, in particular, the natural literals ending with `p`. Now it should be `n`, as in `10n`. - I renamed the node `TAlias` to `TVar`. - I have applied the rule of expanding type expressions after `of` when those were not records. - The type of the argument to a data constructor is now `type_expr`, instead of `cartesian`. - I added the patterns for bytes (`PBytes`) and natural literals (`PNat`). - I renamed the node `Sugar` into `PListComp` (meaning "pattern of list comprehension"). - Record types in CameLIGO now must have at least one field declaration. - Replaced the type `closing` and `opening` with one type `compound`, which captures only the right combinations of opening and closing. - Components of tuples in a selection must not be written between parentheses. For example, `a.b.(1).(0)` is now `a.b.1.0`, as in PascaLIGO. - LexToken.mli/LexToken.mll - I renamed the string literal `Str` into `String`. - I added the tokens `C_None` and `C_Some` (to distinguish the constructors `None` and `Some`. See AST.ml) - Fixed the function `mk_sym` so it does not fail with `failwith`, but with `Error Invalid_symbol`. - Lexer.mll (shared) - I removed the character `%` from the identifiers (used to support Liquidity, like `entry%point` and `match%nat`). - I adde to the hint on broken strings: "or insert a backslash" (from a Gitlab issue). - ParToken.mly - I added the tokens `C_None` and `C_Some` (to distinguish the constructors `None` and `Some`. See AST.ml and LexToken.mll) - Parser.mly - Fixed the order of declarations in the AST (it was reversed). - I removed syntax support for Liquidity. - I added user-defined constructor applications to irrefutable patterns (the ones afer a `let`), even though only the type checker can decide that they are truly irrefutable because they are the only constructors of their types. - I added natural numbers and bytes to patterns. - Access of tuple components do not require parentheses now, like `a.b.1.0`. - I refactored the semantic actions. - I added the empty sequence `begin end`. - ParserLog.ml/ParserLog.mli - I added a pretty-printer for the AST (with source locations). - ParserMain.ml - The CLI for the pretty-printer is now `--verbose=ast`. - The old CLI `--verbose=ast` is now `--verbose=ast-tokens`. - ligodity.ml (simplifier) - I removed the constructions of sets, lists and maps with `Set [...]`, `List [...]` and `Map [...]`, as there are already better ways (that is, more like the OCaml's way), like `Set.literal [...]` and `Map.literal [...]`. (The case for lists was entirely redundant with the rest of the language as it is.) - Everywhere there is now a non-empty list of elements, I made a change. In particular, I removed a corner case ("let without binding"), thanks to more precise OCaml types for non-empty lists. - I ported all the changes to the AST above. - region.ml (vendors) - I changed the method `compact` so the end-line is not repeated if it is the same as the start line: this is even more compact. I use this in the new pretty-printer for the AST (see above) - I updated all the CameLIGO contracts. 2019-11-04 23:51:47 +01:00			`let result = 42 in result`
