Trace the input and output of a function f
named name
,
both down to depth
.
This is useful for adding around a function call, to see the before/after of values as they are transformed.

depth
-
1. Function argument
name
-
2. Function argument
f
-
3. Function argument
v
-
4. Function argument
Examples
lib.debug.traceFnSeqN
usage example
traceFnSeqN 2 "id" (x: x) { a.b.c = 3; }
trace: { fn = "id"; from = { a.b = {…}; }; to = { a.b = {…}; }; }
=> { a.b.c = 3; }

Implementation
The following is the current implementation of this function.
traceFnSeqN = depth: name: f: v:
let res = f v;
in lib.traceSeqN
(depth + 1)
{
fn = name;
from = v;
to = res;
}
res;
