go/parser,go/types: hide API changes related to type parameters While the dev.typeparams branch was merged, the type parameter API is slated for go1.18. Hide these changes to the go/parser and go/types API. This was done as follows: + For APIs that will probably not be needed for go1.18, simply unexport them. + For APIs that we expect to export in go1.18, prefix symbols with '_', so that the planned (upper-cased) symbol name is apparent. + For APIs that must be exported for testing, move both API and tests to files guarded by the go1.18 build constraint. + parser.ParseTypeParams is unexported and copied wherever it is needed. + The -G flag is removed from gofmt, replaced by enabling type parameters if built with the go1.18 build constraint. Notably, changes related to type parameters in go/ast are currently left exported. We're looking at the AST API separately. The new API diff from 1.16 is: +pkg go/ast, method (*FuncDecl) IsMethod() bool +pkg go/ast, method (*ListExpr) End() token.Pos +pkg go/ast, method (*ListExpr) Pos() token.Pos +pkg go/ast, type FuncType struct, TParams *FieldList +pkg go/ast, type ListExpr struct +pkg go/ast, type ListExpr struct, ElemList []Expr +pkg go/ast, type TypeSpec struct, TParams *FieldList +pkg go/types, type Config struct, GoVersion string Change-Id: I1baf67e26279b49092e774309a836c460979774a Reviewed-on: https://go-review.googlesource.com/c/go/+/295929 Trust: Robert Findley <rfindley@google.com> Trust: Robert Griesemer <gri@golang.org> Run-TryBot: Robert Findley <rfindley@google.com> TryBot-Result: Go Bot <gobot@golang.org> Reviewed-by: Robert Griesemer <gri@golang.org>
