Changelog for morley-1.19.0

1.19.0

!1273 Add LAMBDA_REC and Lambda_rec support
- Typed instructions AnnLAMBDA and newly introduced AnnLAMBDA_REC do not carry VLam any more, instead they carry RemFail directly.
- New data type LambdaCode' introduced, with two constructors, for plain and recursive lambdas, respecively.
- VLam now contains LambdaCode' instead of RemFail.
- New function mkVLamRec for constructing recursive lambda values introduced.
!1278 Deprecate OPEN_CHEST, related types and values
!1281 Use the new binaries names, octez-client and octez-node
!1270 Add lima protocol TICKET instruction, rename old one to TICKET_DEPRECATED
- The TICKET instruction was renamed to TICKET_DEPRECATED
- A new TICKET instruction was added which no longer allows zero amount tickets. It now returns Some Ticket and None in case of zero amount supplied.
!1288 Fix toExpression in nested right pair combs with variable annotations
- Conversion to Micheline would lose variable annotations on nested right pair combs. This issue has been fixed.
!1271 Deprecate AssertTypesEqual
- Use FailUnlessEqual instead.
!1193 Use nest from Text.PrettyPrint.Leijen in instructions rendering instead of Morley.Michelson.Printer.Util.spaces
!1265 Add parser for ConstrainedAddress parseConstrainedAddress
- Better address parser error reporting
- Added FromJSON instance for ConstrainedAddress
!1248 Add HasAnnotation deriving to deriveRPC
- New datatype Morley.AsRPC.DeriveRPCOptions
- New helper Morley.AsRPC.deriveRPCWithOptions
- deriveRPCWithStrategy, deriveManyRPC, deriveManyRPCWithStrategy are deprecated in favor of deriveRPCWithOptions
- deriveRPC now behaves as deriveManyRPC, and additionally tries to derive HasAnnotation. It will error out if HasAnnotation is not in scope.
!1258 Support implicit delegation in interpreter
- Reworked delegate tracking in morley interpreter.
- Added unImplicitAddress :: ImplicitAddress -> KeyHash utility to Morley.Tezos.Address.
!1188 Straighten out detSecretKey's behavior
- Add Morley.Tezos.Crypto.KeyType enum type encoding secret/public key type.
- Refactor HashTag to use KeyType.
- detSecretKey now chooses key type based on the seed, not seed length.
- Add detSecretKey' allowing to choose what key type to use.
!1230 Fix secp256k1 signatures
- Roughly half of all secp256k1 created by Morley were rejected by network due to an implementation mismatch. This has been fixed.
!1260 Refactor SomeAddressOrAlias
- Changed the definition of SomeAddressOrAlias to be able to parse address/aliases of a contract, implicit account, or both. A prefix of implicit: or contract: can be used to disambiguate.
- Changed the parser of AddressOrAlias kind to accept the implicit: and contract: prefixes.
- Replaced the morley transfer --to-implicit and --to-contract options with a single --to option.
!1255 Simplify some machinery using instances from some
!1138 Generalize typechecking to work with arbitrary instruction wrapper instead of ExpandedOp.
- Renames:
  - TcInstrHandler to TcInstr;
  - typeCheckOpImpl to typeCheckExpandedOp;
  - TCError to TcError and TCTypeError to TcTypeError;
  - SomeInstr to SomeTcInstr;
- Some functions/types (TCError, typeCheck*) now have primed (') versions that are generalized over ExpandedOp. Those functions now accept the typechecker for ExpandedOp.
!1240 Add MichelsonExt to MichelsonFailed to allow extensible failure.
!1206 Add tupleFromRec
!1243 Add run_code emulation to Morley
- Morley.Michelson.Runtime now provides runCode function, mimicing the functionality of RPC run_code endpoint
!1241 Add classified typed instruction machinery
- See Morley.Michelson.Typed.ClassifiedInstr haddocks for more information.
!1242 Add Constrained utility existential
- New utility module Morley.Util.Constrained introduced, defining an existential Constrained, similar to Some from some, but capturing additional constraints on the GADT argument
- ConstrainedAddress reimplemented in terms of Constrained
- MkConstrainedAddress kept as a pattern synonym, but deprecated
- Types and pattern synonyms from Morley.Michelson.Typed.Existential reimplemented in terms of Constrained
!1245 Remove Guard from Morley.Util.Type
- See #865 for an alternative
!1237 Track delegate registration in interpreter
!1178 Add HasNoNestedBigMaps t constraint to WellTyped requirement for Contract t.
- This is indirectly enforced by the network, but was missing. Useful to avoid redundant checks.
!1228 Handle implicit default entrypoint in mkEntrypointsMap
- Add a new enum type HandleImplicitDefaultEp to signal how to handle implicit default entrypoint.
- Change mkEntrypointsMap to accept HandleImplicitDefaultEp as its first argument. The old behaviour corresponds to calling it with WithoutImplicitDefaultEp.
- Change flattenEntrypoints to accept HandleImplicitDefaultEp, similar to mkEntrypointsMap.
!1195 Improve Forbid constraints to carry type equality evidence
!1222 Change the constraints on instrCase in Morley.Michelson.Typed.Haskell.Instr.Sum and on instrConstruct, instrConstructStack, and instrDeconstruct in Morley.Michelson.Typed.Haskell.Instr.Product. Code using these functions in surprisingly polymorphic ways may need minor adjustments. Applications of these functions should now be faster to typecheck and also faster to run.
!1216 Add LazyTake, a "lazier" version of Take
- Use LazyTake to improve type inference for various functions.
- Rearrange ConstraintDIG' and ConstraintDUG' to reveal a bidirectional functional dependency.
- Remove the KnownList inp constraint from ConstraintDig'.

1.16.0

!1011 Support working with delegates in the morley interpreter

- New helpers in "Morley.Michelson.Parser.Helpers": sepBy1 and some', which are versions of Megaparsec's sepBy1 and some returning a NonEmpty instead of [].
- Removed mparens from "Morley.Michelson.Parser.Helpers": it happens to be unused now, and can be pretty dangerous.
- Removed typeWithParen from "Morley.Michelson.Parser.Type", since it was completely equivalent to just type_, but its performance was slightly worse.
!941 Use pretty-printer in PRINT instruction
- New RenderDoc instance for typed Values without operations
- Some places that were using Buildable Value instance changed to use buildRenderDoc to preserve HasNoOp constraint (where it makes sense, i.e. outside of other Buildable instances)

1.7.0

!565 Remove useless error entities from Michelson.Interpret.

!449
- Improve Michelson.Test.Integrational interface.
- Remove IntegrationalValidator, SuccessValidator, validate, composeValidators, composeValidatorsList, expectAnySuccess.
- Add unexpectedInterpreterError, attempt, catchExpectedError.
- Change type of expect*/tExpect* functions. They now return IntegrationalScenario instead of SuccessValidator / Bool.

- Replace TestError's UnexpectedExecutorError constructor with InterpreterError and UnexpectedInterpreterError.
!441 Remove tezos-bake-monitor-lib dependency, and define value to json conversion using binary round trip locally instead.
!448 Remove base-noprelude dependency and use mixins to hide Prelude instead.
!367 Values and instructions now carry some extra constraints in order to avoid construction of illegally typed values from within Haskell. WellTyped now also requires Typeable and SingI constraints.
!409
- Add hedgehog support
!438
- Fixed parsing bug: support semicolons after block comments.
!424 Changed contract address computation logic in the interpreter to match the reference implementation a bit more closely by including a global counter and an origination index (nonce) to contract's hash. Specifically, now the same contract may be originated several times, leading to different addresses, just like in Tezos.

1.3.0

!417 Change the license to MIT.
!386
- Add a way to describe constructors and fields of ADTs in Markdown documentation.
- Require that all contracts include documentation for the storage type.
!396 Fixed typed Notes to permit pair annotations for container keys.
!359 Renamed 'FullContract' to 'Contract', removed the prefix f from its record fields and removed "Full" from the names of the functions: convertFullContract, printTypedFullContract and mapFullContractCode.
!354
- Fix bug: add ChainId to IsPrimitiveValue type family.
- Add GInstrDeconstruct type class and related functions which serve to deconstruct datatype into its fields on the stack.
- Add gInstrConstructStack to GInstrConstruct type class that serves to construct a datatype from its fields on the stack.
- Add GFieldNames type family returning list of Symbols: the names of direct fields of datatype.

1.2.0

!343
- Make pairs comparable and available to use as map keys and in sets.
- CT type has been integrated into T.
- A WellTyped type class has been added to ensure that a type represented by T is valid as per Michelson's rules.
!358 Remove deprecated STEPS_TO_QUOTA instruction.
!368
- Update JSON encoding of types.
- Rename fields of the untyped Contract'.
!286 Morley supports field annotations for parameter root now.
!344 Fixed a bug in Michelson.Analyzer and added linearizeLeftDeep.

1.1.0

!337 Added an extension for Michelson comment to typed and untyped contract representation.
!306 Added PAIR/UNPAIR rule to optimizer.
!314 Fixed a bug in the implementation of MAP operation: it did not preserve modifications to stack.
!261 Slightly modified interpreter API.
!313 Made typeCheckValue polymorphic in desired type, instead of using existential wrappers.
!310
- Add DGeneralInfoSection documentation section with git revision and potentially other info.
- Add buildLorentzDocWithGitRev and buildInstrDocWithGitRev to API to add a git revision to contract docs from the executable.
!121 BALANCE instruction now returns the balance with funds from incoming transaction.
!294
- Added Paths_* modules to autogen-modules in cabal files. Removed -O0
- from default GHC options. Please set ghc-options in your stack.yaml or cabal.project.local.
!271 Renamed 'Contract' to 'ContractCode', and appended "Code" to the names of two functions: 'convertContract' and 'printTypedContract'
!278 Added some utilities for command line option parsing, see Util.CLI and Morley.CLI modules.
!268 Test functions which import typed contract now return FullContract instead of Contract, thus preserving parameter and storage annotations. In case you don't need this behaviour, use fcCode for conversion. Test functions which import Lorentz contracts have been removed because they cannot be implemented sanely, and Lorentz is assumed to be used to generate code, do not use it for work with textual Michelson contracts.
!212
- Fix AND instruction return type.
- Add DUP n macro support.
- Fix LAMBDA instruction printer.
!265 The semicolons between instructions are now optional.

1.0.0

!215 Major change: all Lorentz functionality was moved into lorentz package. A small portion of testing library code was moved around (from Lorentz.* to Michelson.* or vice versa).

0.7.0

!237 The option (nat %foo) is now accepted syntax. The %foo is ignored.
!241 Derive Show instance for Void_.
!238
- NoExplicitDefaultEntrypoint is now GHC-understandable constraint, for previous behaviour with nice error message use ForbidExplicitDefaultEntrypoint.
- CanHaveEntrypoints is made stricter, now it returns true only for Michelson sum types. If that's a problem for you, consider using ShouldHaveEntrypoints wrapper.
- Added pseudo Empty type.
!219 Various entrypoints-related updates.
- Integrational tests now carry TAddress as a reference to contract. Make sure that parameters of the originated contracts are clear; e.g. origination of consumer contract may require explicit type annotation to specify parameter type. If you passed a reference to the originated contract to View constructor, consider using mkView instead or applying callingDefTAddress to the reference.
- Generally it is encouraged to use TAddress instead of Address where it is used to refer to a contract.
- fromContractAddr renamed to fromContractRef.
- Default instances for {Some,}EntrypointCall are removed, use one of explicit versions: epcPrimitive, epcCallRootUnsafe.
- Reworked FutureContract type.

0.6.0

!127 Limit annotations' allowed characters
!184 Fix LAMBDA instruction type converter bug
!173 !197 Add support for lightweight entrypoints in Lorentz, as well as in the interpreter runner and morley executable. Support entrypoint references in SELF instruction. Minor refactorings related to entrypoints.
!201
- Add entrypoint argument to methods in testing eDSL. Preserve the existing type of lCall and deprecate it.
- Deprecate Lorentz.TestScenario.
!208 Resolve an ambiguity within integrational and unit interpreters by renaming interpreter in Michelson.Runtime to executor.
!180 Remove coerce_ in favor of more safe variants. Migration guide: pick one of the functions from 'Lorentz.Coercions' module. In most cases you need one of the following ones:
- checkedCoerce_
- coerceWrap / coerceUnwrap
- forcedCoerce_ (aka old coerce_ - this variant provides the least safety).
!180 Type arguments of coerceWrap and coerceUnwrap are flipped. This change concerns you if you used type application on these functions.

0.5.0

Require morley-prelude to be ≥ 0.3.0 to make Hackage happy.
!156 Consider annotations in PACK and UNPACK.

0.4.0
