AST String method
Closed this issue · 5 comments
Would like a method to generate the string representation of an AST object that could be directly used in a query. For example, if had a Field that was generated from
object(id:$id){ id name value subobject(index:9){ id name }}
would like to be able to call something like
ast.String(field)
to return an equivalent string.
I wrote a utility function to do this in my own project, but it is specific to ast.Field and doubt it covers all possible definitions:
func fieldQueryString(field *ast.Field) string {
query := field.Name
if len(field.Arguments) > 0 {
query += "("
for _, arg := range field.Arguments {
query += arg.Name + ":"
query += field.Arguments.ForName(arg.Name).Value.String()
}
query += ")"
}
if len(field.SelectionSet) > 0 {
query += "{"
for _, f := range field.SelectionSet {
field := f.(*ast.Field)
query += fieldQueryString(field) + ","
}
query += "}"
}
return query
}
I think this would be generally useful for logging/debugging.
Apologies if this already exists, please point to where it is found if exists.
Opening issue in this repo as suggested in 99designs/gqlgen#723.
Thank you! Appreciate it.
Hello @vektah @scraymondjr !
How can I use formatter for getting query string from *ast.Field?

Understood how it is possible. Thank you!
