I'm looking to use the golang library to implement a function that walks the structure and grabs all fields regardless of the field constraints, as in first!:, second: and third?:, so far I don't have issues with first and second but I've not been able to get third unless it's been given a value.
Solution:
go mod tidy
go run .
cmp stdout stdout.golden
-- go.mod --
module mod.com
go 1.21.4
require cuelang.org/go v0.7.0
-- main.go --
package main
import (
"fmt"
"log"
"cuelang.org/go/cue"
"cuelang.org/go/cue/cuecontext"
)
const src = `
x?: string
y!: string
z: string
`
func main() {
ctx := cuecontext.New()
v := ctx.CompileString(src)
fields, err := v.Fields(
cue.Optional(true),
cue.Hidden(true),
cue.Definitions(true),
)
if err != nil {
log.Fatal(err)
}
for fields.Next() {
fmt.Printf("found field %v\n", fields.Selector())
}
}
-- stdout.golden --
found field x?
found field y!
found field z
