Unresolved reference

[zolotov]

package main

type Type interface {
    Size() int64
}

type ArrayType struct {
    Type Type
}

func zeroArray(t *Type) {
    at, _ := (*t).(*ArrayType)
    println(at.Type) // shouldn't be a error
    println(at.Type.Size) // shouldn't be a error
}

I'm just trying out Squirell and when I try the Postgres example:

package main

import sq "github.com/Masterminds/squirrel"

func main() {
    sq.StatementBuilder.PlaceholderFormat(sq.Dollar)
}

v0.9.562 gives me Unresolved Reference on PlacehodlerFormat (and then on subsequent calls). If I read it correctly, this is the same issue and therefore already fixed, right?

@mingan there are a lot of rules on resolving in Go and code samples from the issue and from your comment look completely different, so I guess it's another resolving issue.

I think this is a good isolated reproduction for the issue described by @mingan:

package main

type PlaceholderFormat interface {
    ReplacePlaceholders(sql string) (string, error)
}
type Builder struct{}
type StatementBuilderType Builder

func (b StatementBuilderType) PlaceholderFormat(f PlaceholderFormat) StatementBuilderType {
    return (struct{}{}).(StatementBuilderType)
}

var EmptyBuilder = Builder{}
var StatementBuilder = StatementBuilderType(EmptyBuilder).PlaceholderFormat()

func main() {
    StatementBuilder.PlaceholderFormat(struct{})
}

@zolotov thank you for your quick reply. I see you reopened this issue already.

Building on @dlsniper's example: the incorrect highlighting occurs only when called in a function. Any directly chained calls are fine:

var StatementBuilder = StatementBuilderType(EmptyBuilder).PlaceholderFormat().PlaceholderFormat()
