Load build YAML to Cue inside Golang code

[roylisto]

Hi I have a YAML file

a:
  foo: bar

And try to load it to golang code

ctx := cuecontext.New()
yamlContent, _ := ioutil.ReadFile("test.yaml")
yamlValue := ctx.CompileBytes(yamlContent)
fmt.Println(yamlValue)

then I get this error
_|_ // 2:8: reference "bar" not found

but if I use
foo: "bar"
It works

is this a bug or expected by ctx.CompileBytes() ?

the context is I need to validate YAML files by cue definition inside golang code

@roylisto the cue.Context methods are for loading CUE. You are looking for https://pkg.go.dev/cuelang.org/[email protected]/encoding/yaml#Extract, the result of which can then be built using cue.Context.BuildFile().

oh okay, and I found all I need is this function https://pkg.go.dev/cuelang.org/go/pkg/encoding/yaml#Validate

[roylisto]

`yamlFile, _ := ioutil.ReadFile("test.yaml")

valid, err := yaml.Validate(yamlFile, cueValue)`

Ah for plain yaml validation, yes.
