Script (de)serialization
type SerialisedScript = ShortByteString Source #
Scripts to the ledger are serialised bytestrings.
data ScriptForEvaluation Source #
A Plutus script ready to be evaluated on-chain, via evaluateScriptRestricting.
Instances
serialisedScript :: ScriptForEvaluation -> SerialisedScript Source #
Get a SerialisedScript from a ScriptForEvaluation. O(1).
deserialisedScript :: ScriptForEvaluation -> ScriptNamedDeBruijn Source #
Get a ScriptNamedDeBruijn from a ScriptForEvaluation. O(1).
serialiseCompiledCode :: forall a. CompiledCode a -> SerialisedScript Source #

serialiseUPLC :: Program DeBruijn DefaultUni DefaultFun () -> SerialisedScript Source #
Turns a program's AST (most likely manually constructed) into a binary format that is understood by the network and can be stored on-chain.
Arguments
| :: forall m. MonadError ScriptDecodeError m | |

| -> SerialisedScript | the script to deserialise. |
| -> m ScriptForEvaluation |
The deserialization from a serialised script into a ScriptForEvaluation,

Script evaluation
evaluateScriptCounting Source #
Arguments
| :: PlutusLedgerLanguage | The Plutus ledger language of the script under execution. |
| -> MajorProtocolVersion | Which major protocol version to run the operation in |
| -> VerboseMode | Whether to produce log output |
| -> EvaluationContext | Includes the cost model to use for tallying up the execution costs |
| -> ScriptForEvaluation | The script to evaluate |
| -> [Data] | The arguments to the script |
| -> (LogOutput, Either EvaluationError ExBudget) |
Evaluates a script, returning the minimum budget that the script would need
to evaluate successfully. This will take as long as the script takes, if you need to
limit the execution time of the script also, you can use evaluateScriptRestricting, which
also returns the used budget.
Note: Parameterized over the ledger-plutus-version since the builtins allowed (during decoding) differs.
evaluateScriptRestricting Source #
Arguments
| :: PlutusLedgerLanguage | The Plutus ledger language of the script under execution. |
| -> MajorProtocolVersion | Which major protocol version to run the operation in |
| -> VerboseMode | Whether to produce log output |
| -> EvaluationContext | Includes the cost model to use for tallying up the execution costs |
| -> ExBudget | The resource budget which must not be exceeded during evaluation |
| -> ScriptForEvaluation | The script to evaluate |
| -> [Data] | The arguments to the script |
| -> (LogOutput, Either EvaluationError ExBudget) |
Evaluates a script, with a cost model and a budget that restricts how many resources it can use according to the cost model. Also returns the budget that was actually used.
Can be used to calculate budgets for scripts, but even in this case you must give a limit to guard against scripts that run for a long time or loop.
Note: Parameterized over the LedgerPlutusVersion since
1. The builtins allowed (during decoding) differ, and
2. The Plutus language versions allowed differ.
evaluateTerm :: ExBudgetMode cost DefaultUni DefaultFun -> MajorProtocolVersion -> VerboseMode -> EvaluationContext -> Term NamedDeBruijn DefaultUni DefaultFun () -> (Either (CekEvaluationException NamedDeBruijn DefaultUni DefaultFun) (Term NamedDeBruijn DefaultUni DefaultFun ()), cost, [Text]) Source #
Evaluate a fully-applied term using the CEK machine. Useful for mimicking the behaviour of the on-chain evaluator.
data VerboseMode Source #
A simple toggle indicating whether or not we should accumulate logs during script execution.
Instances
| Eq VerboseMode Source # | |
Defined in PlutusLedgerApi.Common.Eval Methods (==) :: VerboseMode -> VerboseMode -> Bool Source # (/=) :: VerboseMode -> VerboseMode -> Bool Source # | |
type LogOutput = [Text] Source #
The type of the executed script's accumulated log output: a list of Text.
It will be an empty list if the VerboseMode is set to Quiet.
data EvaluationError Source #

Constructors
| CekError !(CekEvaluationException NamedDeBruijn DefaultUni DefaultFun) | An error from the evaluator itself |
| DeBruijnError !FreeVariableError | An error in the pre-evaluation step of converting from de-Bruijn indices |
| CodecError !ScriptDecodeError | A deserialisation error TODO: make this error more informative when we have more information about what went wrong |
| CostModelParameterMismatch | An error indicating that the cost model parameters didn't match what we expected |
| InvalidReturnValue | The script evaluated to a value that is not a valid return value. |

Network's versioning
The network's behaviour (and plutus's by extension) can change via hard forks, which directly correspond to major-number protocol version bumps.
newtype MajorProtocolVersion Source #
This represents the major component of the Cardano protocol version. The ledger can only supply the major component of the protocol version, not the minor component, and Plutus should only need to care about the major component anyway. This relies on careful understanding between us and the ledger as to what this means.
Constructors
| MajorProtocolVersion | |
Fields | |
Instances
data PlutusLedgerLanguage Source #
The Plutus ledger language. These are entirely different script languages from the ledger's perspective, which on our side are interpreted in very similar ways.
It is a simple enumerated datatype (there is no major and minor components as in protocol version) and the ordering of constructors is essential for deriving Enum,Ord,Bounded.
IMPORTANT: this is different from the Plutus Core language version, Version

fromSatInt :: Num a => SatInt -> a #
Network's costing parameters
A less drastic approach (that does not rely on a HF) to affect the network's (and plutus's by extension) behaviour is by tweaking the values of the cost model parameters.
The network does not associate names to cost model parameters; Plutus attaches names to the network's cost model parameters (values) either in a raw textual form or typed by a specific plutus version.
See Note [Cost model parameters]
type CostModelParams = Map Text Int64 #
toCostModelParams :: IsParamName p => [(p, Int64)] -> CostModelParams Source #
Untags the plutus version from the typed cost model parameters and returns their raw textual form (internally used by CostModelInterface).
assertWellFormedCostModelParams :: MonadError CostModelApplyError m => CostModelParams -> m () Source #
class (Enum a, Bounded a) => IsParamName a where Source #
A parameter name for different plutus versions.
Each Plutus version should expose such an enumeration as an ADT and create
an instance of ParamName out of it.
A valid parameter name has to be enumeration, bounded, ordered, and prettyprintable to a "lower-Kebab" string.
Minimal complete definition
Methods
showParamName :: a -> Text Source #
Produce the raw textual form for a given typed-by-plutus-version cost model parameter
Any implementation *must be* an injective function.
The GIsParamName generic implementation guarantees injectivity.

default implementation that inverts the showParamName operation (not very efficient)

Evaluation context
data EvaluationContext Source #
An opaque type that contains all the static parameters that the evaluator needs to evaluate a script. This is so that they can be computed once and cached, rather than being recomputed on every evaluation.
Different protocol versions may require different bundles of machine parameters, which allows us for
example to tweak the shape of the costing function of a builtin, so that the builtin costs less.
Currently this means that we have to create multiple DefaultMachineParameters per language
version, which we put into a cache (represented by an association list) in order to avoid costly
recomputation of machine parameters.
In order to get the appropriate DefaultMachineParameters at validation time we look it up in the
cache using a semantics variant as a key. We compute the semantics variant from the protocol
version using the stored function. Note that the semantics variant depends on the language version
too, but the latter is known statically (because each language version has its own evaluation
context), hence there's no reason to require it to be provided at runtime.
To say it differently, there's a matrix of semantics variants indexed by (LL, PV) pairs and we
cache its particular row corresponding to the statically given LL in an EvaluationContext.
The reason why we associate a DefaultMachineParameters with a semantics variant rather than a
protocol version are
- generally there are far more protocol versions than semantics variants supported by a specific language version, so we save on pointless duplication of bundles of machine parameters
- builtins don't know anything about protocol versions, only semantics variants. It is therefore more semantically precise to associate bundles of machine parameters with semantics variants than with protocol versions

mkDynEvaluationContext :: MonadError CostModelApplyError m => PlutusLedgerLanguage -> [BuiltinSemanticsVariant DefaultFun] -> (MajorProtocolVersion -> BuiltinSemanticsVariant DefaultFun) -> CostModelParams -> m EvaluationContext Source #
Create an EvaluationContext given all builtin semantics variants supported by the provided
language version.
The input is a Map of Texts to cost integer values (aka CostModelParams, CostModel)
See Note [Inlining meanings of builtins].
IMPORTANT: the toSemVar argument computes the semantics variant for each MajorProtocolVersion
and it must only return semantics variants from the semVars list, as well as cover ANY
MajorProtocolVersion, including those that do not exist yet (i.e. toSemVar must never fail).
IMPORTANT: The evaluation context of every Plutus version must be recreated upon a protocol update with the updated cost model parameters.
toMachineParameters :: MajorProtocolVersion -> EvaluationContext -> DefaultMachineParameters Source #
Arguments
| :: MonadError EvaluationError m | |
| => PlutusLedgerLanguage | the Plutus ledger language of the script under execution. |
| -> MajorProtocolVersion | which major protocol version to run the operation in |
| -> ScriptForEvaluation | the script to evaluate |
| -> [Data] | the arguments that the script's underlying term will be applied to |
| -> m (Term NamedDeBruijn DefaultUni DefaultFun ()) |
Shared helper for the evaluation functions: evaluateScriptCounting and evaluateScriptRestricting,
Given a ScriptForEvaluation:
1) applies the term to a list of Data arguments (e.g. Datum, Redeemer, ScriptContext)
2) checks that the applied-term is well-scoped
3) returns the applied-term

class Monad m => MonadError e (m :: Type -> Type) | m -> e Source #
The strategy of combining computations that can throw exceptions by bypassing bound functions from the point an exception is thrown to the point that it is handled.
Is parameterized over the type of error information and
the monad type constructor.
It is common to use Either StringMonadError class.
You can also define your own error type and/or use a monad type constructor
other than Either StringEither IOErrorMonadError
class.
(If you are using the deprecated Control.Monad.Error or
Control.Monad.Trans.Error, you may also have to define an Error instance.)
