Overview ¶
Package ast provides tools for manipulating the flux ast. Eventually this will become a builder api.

Types ¶
type Extern ¶
type Extern struct {
Body []variableAssignment `json:"body"`
}
Extern is what we use to marshal something that will get unmarshaled in flux as an ast.File.
func FluxExtern ¶
FluxExtern is a function that generates an extern given a struct or map[string]<whatever>. It reflects over the object to generate variables.
Example (Map) ¶
buf := &strings.Builder{}
enc := json.NewEncoder(buf)
ext, err := FluxExtern(map[string]string{
"bucket": "my-bucket",
})
if err != nil {
log.Fatal(err)
}
if err := enc.Encode(ext); err != nil {
log.Fatal(err)
}
fmt.Println(buf.String())
Output: {"type":"File","body":[{"type":"VariableAssignment","id":{"type":"Identifier","name":"bucket"},"init":{"type":"StringLiteral","value":"my-bucket"}}]}
Example (Struct) ¶
buf := &strings.Builder{}
enc := json.NewEncoder(buf)
ext, err := FluxExtern(struct {
Bucket string `flux:"bucket"`
OtherVariable string `flux:"otherVariable,omitempty"`
}{
Bucket: "my-bucket",
})
if err != nil {
log.Fatal(err)
}
if err := enc.Encode(ext); err != nil {
log.Fatal(err)
}
fmt.Println(buf.String())
Output: {"type":"File","body":[{"type":"VariableAssignment","id":{"type":"Identifier","name":"bucket"},"init":{"type":"StringLiteral","value":"my-bucket"}}]}
func (Extern) MarshalJSON ¶
MarshalJSON marshals an Extern so that flux can read it.
