(mem)

field access expressions

(mem field? value?)

Where:

1. field: field name (the b in a.b) *
2. value: receiver expression (the a in a.b) *

Matching:

1. field access, e.g. value.field
2. chained access, e.g. value.field.subfield

Behavior

• When value is provided and the receiver is a chained access, it matches the inner field name (so (mem _ config) matches settings.config.value).

Examples

Find accesses to secrets on a config struct.

(mem secret (id config))

Selects in lines { 1 } but not in { 2, 3 }:

let token = config.secret;
let token = settings.secret;
let level = config.verbose;

---

Locate chained accesses that go through a config field.

(mem _ config)

Selects in lines { 1 } but not in { 2 }:

let path = settings.config.value;
let path = settings.env.value;
