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

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

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

Example 4

1

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.
