v0.7.0

v0.7.0 is a small release that makes a couple of breaking changes since v0.6.0.
However, the good news is: they're all very small changes, and we've kept them in a tiny group,
so if you're already on v0.6.0, this update should be easy.
And we've got scripts to help you.

There's also one cool new feature: traversal.FocusedTransform is now available to help you make mutations to large documents conveniently.

• Change: all interfaces and APIs now use golang int64 rather than golang int. #125
  • This is necessary because the IPLD Data Model specifies that integers must be "at least 2^53" in range, and so since go-ipld-prime may also be used on 32-bit architectures, it is necessary that we not use the int type, which would fail to be Data Model-compliant on those architectures.
  • The following GNU sed lines should assist this transition in your code, although some other changes that are more difficult automate may also be necessary:

     sed -ri 's/(func.* AsInt.*)\<int\>/\1int64/g' **/*.go
     sed -ri 's/(func.* AssignInt.*)\<int\>/\1int64/g' **/*.go
     sed -ri 's/(func.* Length.*)\<int\>/\1int64/g' **/*.go
     sed -ri 's/(func.* LookupByIndex.*)\<int\>/\1int64/g' **/*.go
     sed -ri 's/(func.* Next.*)\<int\>/\1int64/g' **/*.go
     sed -ri 's/(func.* ValuePrototype.*)\<int\>/\1int64/g' **/*.go
    

• Change: we've renamed the types talking about "kinds" for greater clarity. ipld.ReprKind is now just ipld.Kind; schema.Kind is now schema.TypeKind. We expect to use "kind" and "typekind" consistently in prose and documentation from now on, as well. #127
  • Pretty much everyone who's used this library has said "ReprKind" didn't really make sense as a type name, so, uh, yeah. You were all correct. It's fixed now.
  • "kind" now always means "IPLD Data Model kind", and "typekind" now always means "the kinds which an IPLD Schema type can have".
  • You can find more examples of how we expect to use this in a sentence from now on in the discussion that lead to the rename: #94 (comment)
  • The following GNU sed lines should assist this transition in your code:

     sed -ri 's/\<Kind\(\)/TypeKind()/g' **/*.go
     sed -ri 's/\<Kind_/TypeKind_/g' **/*.go
     sed -i 's/\<Kind\>/TypeKind/g' **/*.go
     sed -i 's/ReprKind/Kind/g' **/*.go
    

• Feature: traversal.FocusedTransform works now! 🎉 You can use this to take a node, say what path inside it you want to update, and then give it an updated value. Super handy. #130
