Before encoding a compoundBlob we create a compoundBlobStruct and
encode that instead.
After decoding we check if the value is a compoundBlobStruct and if so
we convert it to a compoundBlob.
Fixes#455, #165
Ref Values now have a TargetRef() method that returns the ref.Ref of
the target the Value is referencing.
Note: This is a breaking change. In old code the Ref() of the Value was
the Ref of the underlying target.
Fixes#464
First cut at creating a shared Noms types package, by creating
'geotypes.noms' to define Geoposition and Georectangle. These are
shared by quad_tree and sfcrime_importer initially, but will also
by used by sfcrime_search and the stuff that works with photos.
quad_tree used to add methods to the generated Geoposition and
Georectangle types. This doesn't work anymore, since these types
are now generated as part of a separate Go package. Fortunately,
these methods are easily re-cast as pure functions.
Towards #409
We'd wound up in a spot where serialization code used 'TypeRefKind' to
mean one of two very different things...either an actual value that
describes some Noms type, or a reference to a type definition that
lives somewhere else. To get rid of this ambiguity, we introduce
'UnresolvedKind' to take over the latter meaning. Now, TypeRefKind
means _only_ a value that describes a type. If you want to point off
to a type definition elsewhere in the type package, or in another
type package, use UnresolvedKind.
grammar.peg didn't get updated along with grammar.peg.go in arv's last patch,
so that needed to be fixed. Also, pkg.Parsed had its own field named Types, which
shadowed the one it got by embedded types.Package. This only came into play when
generating code for packages pulled out of a dataset. Since arv had to manually
patch up all generated code in his last patch, he never hit this issue and I
missed it in review.
Now, go generate passes once more. Yay
Sets, Lists, Refs and Maps of imported types work now.
This PR also factors some of codegen.go into a separate package, to slim down
that file a bit.
Towards issue #294
The new serialization format use "t " as in typed. The rest of the
message is a JSON array describing the typed data. The type is
described by types.TypeRef
Fixes#384
Issues #281, #304
The TypeRef function for a Noms Struct should be the (Name, PkgRef) and
not the description of the struct fields. This is important because
when serializing we need to write the package ref.
Towards #281#304
Also, switch to using a ref.Ref when getting/setting the package
ref in a TypeRef. Using a types.Ref just led to lots of manual
boxing and unboxing every time I wanted to use the reference.
Toward issue #294
This patch mostly merges parse.Package and types.Package, though it
can't quite go all the way. A types.Package doesn't have 'using'
declarations, while the parsed representation of a .noms file needs to
have that information. Hence, the parse package is moved to the 'pkg'
package, and pkg.Parsed is introduced. This type embeds types.Package
and adds the necessary additional information.
To make inroads on handling imports, I enhanced ParsePackage() (now
called ParseNomDL()) to actually process the 'alias' and 'import'
statements in the input and go replace namespaced type names in the
package with refs of imported packages. For example, the TypeRef for
'Bar' generated in the following package
alias Foo = import "sha1-ffffffff"
struct Bar {
f: Foo.RockinStruct
}
will actually return types.Ref{sha1-ffffffff} when you call PackageRef()
on it.
In addition, I've added a function to the new 'pkg' package,
which allows the caller to get the dependencies of a type package
from a chunk store.
Fixes issue #353, towards issue #294
These were two representations of, essentially, the same information.
They were separate because they provided different APIs to similar
information, but the APIs became more similar once we started using
native types (as opposed to Noms types) for the various Make*TypeRef()
functions.
Unifying these is a big step to unifying parse.Package and types.Package,
which is pretty necessary for dealing with imported packages.
Fixes issue #338
