Computes the policy ID of a minting policy; added guards for blueprint address to check that it's not a minting policy; Wasn't 100% sure where the errors should live, so I'm happy to move them if there's objections

* rename flat to encode
* rename unflat to decode
* alias both to their old names
* both only print to stdout
use can pipe to file
* split cbor and hex flags
* hex flag works for either cbor or flat
* encode takes --to flag
[name, named-debruijn, debruijn]
* decode takes --from flag
[name, named-debruijn, debruijn]
The apply command now works only from a serialized CBOR data (instead of a UPLC syntax). So it is no longer possible to specify arbitrary cbor terms through the CLI. I believe it to be an acceptable limitation for now; especially given that Aiken will never generate blueprints with non-data terms at the interface boundary.
These were needed before as a way to _partially deserialize_
blueprints. Indeed, some commands required accessing information of
the blueprint, but not necessarily the schema. So out of laziness (or
cleverness?), we only deserialized validators as serde::Value and
achieved that through the use of generics.
Now that validators and schemas have proper deserialisers, we can
simply deserialize a blueprint.
TODO: Our serialisation/deserialisation is safe with regards to
itself; i.e. it roundtrips. However, we only supports a subset of the
specified blueprint format. For example, we would fail to deserialize
blueprints that have inline data-schemas (we only use references).
This was a bit tricky and I ended up breaking things down a lot and
trying different path. This commit is the result of the most
satisfying one.
It introduces a new 'concept' and types: Definitions and Reference.
These elements are meant to reflect JSON pointers and JSON-schema
definitions which we now use for pretty much all user-defined
data-types.
In fact, Schemas are no longer inlined, but are always referencing
some schema under "definitions".
This indirection is necessary in order to cope with recursive types.
And while it's only truly necessary for recursive types, using it
consistently makes it both easier to produce and easier to consume.
---
The blueprint generation for recursive types here also works thanks to
the 'Definitions' data-structure wrapper around a BTreeMap. This uses
a strategy where:
(1) schemas are only generated if they haven't been seen before
(2) schemas are marked as seen BEFORE actually being generated (to
effectively stop a recursive generation).
This relies on one important aspect: the key must be uniquely
identifying a given schema. Which means that we have to monomorphize
data-types with generic parameters also here, and use keys that are
specialized in one data-type.
---
In this large overhaul we've also lost one thing which I didn't bother
re-introducing yet to keep the work manageable: title for record
fields. Before, we use to pull those from record constructor when
available, yet now, every record constructor has been replaced by a
`$ref`. We could theoritically attach a title to the reference. I'll
try to quickly add that in a later commit.
Tracing is now turn OFF by default when:
- building project
- building documentation
- building dependencies
It can be turned ON only when building project using `--keep-traces`.
That means it's not possible to build dependencies with traces. The
address `--rebuild` flag will also rebuild without traces.
Tracing is however turn ON by default when:
- checking the project (and running tests).
In this scenario, tracing can be disabled using `--no-traces` (if for
example, one want to analyze the execution units of specific functions
without having to manually remove traces from code).
We want the lookup to yield a result when there's only a single
validator; and no title is provided. So that users can simply do
'aiken address' in their project if it's unambiguous. The validator's
name is only required to disambiguate between multiple validators.
I also noticed that the order of arguments in with_validator was
wrong. Somehow.
