yaml-patch

yaml-patch is a version of Evan Phoenix's json-patch, which is an implementation of JavaScript Object Notation (JSON) Patch, but for YAML.

Installing

go get github.com/krishicks/yaml-patch

If you want to use the CLI:

go get github.com/krishicks/yaml-patch/cmd/yaml-patch

API

Given the following RFC6902-ish YAML document, ops:

: add
th: /baz/waldo
lue: fred

And the following YAML that is to be modified, src:

 bar

ux: grault

Decode the ops file into a patch:

h, err := yamlpatch.DecodePatch(ops)
andle err

Then apply that patch to the document:

 err := patch.Apply(src)
andle err

o something with dst

Example

:= []byte(`---
 bar

ux: grault


:= []byte(`---
: add
th: /baz/waldo
lue: fred


h, err := yamlpatch.DecodePatch(ops)
rr != nil {
g.Fatalf("decoding patch failed: %s", err)


err := patch.Apply(doc)
rr != nil {
g.Fatalf("applying patch failed: %s", err)


Println(string(bs))

ux: grault
ldo: fred
 bar
