eval() function

[LeonB]

Would it be possible to add an eval() function?

Would you explain the use case? It evaluates some jq code constructed from the input JSON?

[itchyny]

This is unlikely to be included until jq implements this.

Maybe useful for someone else:

func eval(c interface{}, a []interface{}) gojq.Iter {
	src, ok := a[0].(string)
	if !ok {
		return gojq.NewIter(fmt.Errorf("%v: src is not a string", a[0]))
	}

	gq, err := gojq.Parse(src)
	if err != nil {
		return gojq.NewIter(err)
	}
	gc, err := gojq.Compile(
		gq,
		p.CompilerOptions()...,
	)
	if err != nil {
		return gojq.NewIter(err)
	}

	return gc.Run(c)
}

gojq.WithIterFunction("eval", 1, 1, eval)
