merge

Returns the result of merging two or more maps.

语法

collections.Merge MAP MAP...
merge MAP MAP...

Returns the result of merging two or more maps from left to right. If a key already exists, merge updates its value. If a key is absent, merge inserts the value under the new key.

Key handling is case-insensitive.

The following examples use these map definitions:

1
2
3
{{ $m1 := dict "x" "foo" }}
{{ $m2 := dict "x" "bar" "y" "wibble" }}
{{ $m3 := dict "x" "baz" "y" "wobble" "z" (dict "a" "huey") }}

Example 1

1
2
3
4
5
{{ $merged := merge $m1 $m2 $m3 }}

{{ $merged.x }}   --> baz
{{ $merged.y }}   --> wobble
{{ $merged.z.a }} --> huey

Example 2

2
3
4
5
{{ $merged := merge $m3 $m2 $m1 }}

{{ $merged.x }}   --> foo
{{ $merged.y }}   --> wibble
{{ $merged.z.a }} --> huey

Example 3

4
5
{{ $merged := merge $m2 $m3 $m1 }}

{{ $merged.x }}   --> foo
{{ $merged.y }}   --> wobble
{{ $merged.z.a }} --> huey

Example 4

5
{{ $merged := merge $m1 $m3 $m2 }}

{{ $merged.x }}   --> bar
{{ $merged.y }}   --> wibble
{{ $merged.z.a }} --> huey

Regardless of depth, merging only applies to maps. For slices, use append.
