- 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.
