Since we are working with multiple setoids now, it makes more sense to
qualify their members. Follow the "as P" pattern from the standard
library. Also stop importing those symbols from Relation.Binary.Core as
later agda-stdlib versions will move them away. Rather than EqSetoid or
PropEq, use P.setoid consistently.

These became duplicates of their non-barred counterparts.

All of these changes were applied to functions of type
... -> (x : ...) -> ... == x -> ...
where x could be preceded by just making the x implicit, because it can
be uniquely deduced from the equality proof.

Typically we have the complex term on the LHS and the simplified term on
the RHS. These lemmata did it otherwise and by symming them, we save two
syms.

Albeit long, this commit is relatively boring.

This allows bff to be more precise with regard to its failure modes,
even though we are not yet making use of that projected precision. It
allows inserting a default value for entries that could not be recovered
in a shape changing update as described in VoigtlaenderHMW13.
|
|
|
|
This makes a few proofs easier and eliminates the need for sequence-map
entirely.
|
|
It allows defining get functions that are only defined for some vector
lengths. It retains backwards compatibility with the previous state via
a VecVec compatibility module. The biggest benefit is that now standard
library functions such as tail, take and drop can be passed to bff.

Unlike the original version in VoigtlaenderHMW13, we do not request an
sput : ℕ → ℕ → Maybe ℕ
function for determining the updated source shape from the original
source and updated view shape. Instead we ask the caller directly to
provide the result of sput together with a proof that its getlen matches
with the provided, updated view.
The precondition assoc-enough is not enriched in this way and still
requires a non-changing shape. I.e. it says what it said before.

Most of the became unused by using the convenience functions introduced
in the parent commit.

These two features heavily interconnect. As such it makes sense to
integrate them properly. This non-trivial merge does that work. Compared
to feature-partial-getlen a few definitions moved from FreeTheorems.agda
to GetTypes.agda. Many types changed compared to both branches.

* Remove let patter , match = foo usage
* Remove Qualified.infix-symbol usage
* Add non-obvious absurd patterns
* Qualify constructors

By choosing gl₁ = suc and gl₂ = id, the tail function can now be
bidirectionalized.
|

|
This allows passing both getlen and get as a single parameter. It also
allows to make the free theorem a prerequisite instead of a postulate.
|
|
Most conflicts stem from varying imports or added functions and a
take-both approach merges them. A notable exception is theorem-2, where
a new result sequence-cong was required. Apart from that, theorem-2
could be taken almost verbatim from feature-delete albeit its type
coming from feature-decsetoid.

The old definition of bff had a single failure mode - assoc - and its
proof was a single cong. Now we need to show that the other failure mode
- mapM (flip lookupM ...) - is eliminated by the success of the former
resulting in a larger proof.
|
|
Since the generalization of lemma-checkInsert-restrict there is nothing
to show for theorem-1. So everything works with Setoids now yielding the
same results as the paper proofs.
|
|
This is another step towards permitting arbitrary Setoids in bff.
|
|
The union was the only user of this type and now it uses only partial
mappings. So drop remaining uses of FinMap and make everything work with
FinMapMaybe instead.
|
|
In the presence of shape-changing updates, bff needs to shrink one of
the mappings before unifying them. As long the shape does not change,
the union becomes a disjoint union. With this insight we can adapt the
proof of theorem-1 using the adapted lemma-disjoint-union. Unfortunately
theorem-2 requires more work and assoc-enough becomes non-trivial due to
the introduction of mapMV.
|
|
Also rename fmap to _<$>_ to match Agda naming conventions. The imported
_>>=_ appears to have different binding, so some braces were necessary.
|
|
This removes imports.

Also adapt depending modules. Long lines generally become shorter. The
misleading name "EqInst" (hiding the decidability) got discarded.
|
|
And update Bidir and Precond, cause they import BFF.
|
|
The import of CheckInsert was broken in previous commit.
|

|
|
This way of naming things is more similar to the standard library and to
my own \::-injective. Suggested by Andres Loeh.
|
|
If get on Fin results in Vecs whose elements are unique, then theorem-2
can be applied.
