I ended up writing these templates to convert bracket notation to dot notation:
import macros
macro `[]`*(obj: object, fieldName: string): untyped =
## Access object field value by name: ``obj["field"]`` translates to
``obj.field``.
runnableExamples:
type
Example = object
field: int
let example = Example(field: 123)
doAssert example["field"] == example.field
newDotExpr(obj, newIdentNode(fieldName.strVal))
macro `[]=`*(obj: var object, fieldName: string, value: untyped): untyped =
## Set object field value by name: ``obj["field"] = value`` translates to
``obj.field = value``.
runnableExamples:
type
Example = object
field: int
var example = Example()
example["field"] = 321
doAssert example["field"] == 321
newAssignment(newDotExpr(obj, newIdentNode(fieldName.strVal)), value)
Run
