Details on which fields/attributes were updated

Hi, is there perhaps a way to see which fields have been updated after a merge?
Thanks for opening a new issue. The team has been notified and will review it as soon as possible.

Is this something that is of relevance to this project @imdario? If so, I am happy to contribute to this.
To expand on my understanding of what @jankrynauw is seeking using the demo:
src := Foo{
A: "one",
B: 2,
}
dest := Foo{
A: "two",
}
mergo.Merge(&dest, src)
fmt.Println(dest)
// Will print
// {two 2}
It would be useful to have a way to know that field A
comes from dest
and field B
from src
.
My suggestion would be to have a map[string]string
with the keys being the struct's field paths and the value being the name of the relevant struct. In this example:
map[string]int32{
"A": "dest",
"B": "src",
}
@ruanspies Not sure about this change.
Closing. Maybe it could be considered for v2, but I don't see a real value that outweights the effort to track all merges.
