1) truncate filenames containing hash to only use first 7 chars of hash.
2) change output filename from <base>.go to <base>_noms.go
3) check for includes of file in same directory and don't generate twice.
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
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.
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
This adds code for finding imported type packages and generating
code for them, but does not yet handle generating code that uses
those types.
Towards 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
This make Commit a typed struct with a Set(Commit).
This also fixes a case where the recursive detection for determining
if a Def can be created was not working.
We want to explore encoding type information about Noms data in
the Noms database. So, we need some way to describe types. This
takes the shortest path to making a Noms type called "TypeRef" that
is a peer of Set, Map et al and can describe all the types we currently
use.
Due to limitations in Go we cannot create a Def for a Map or Set that
has a key that is a Map, Set or a List. This is because the key if a Go
map needs to be a comparable and maps and slices are not comparable.
