A package to semantically diff yaml files on the console.
Project description
yamldiff
A semantic YAML diff utility.
yamldiff file1.yaml file2.yaml
will show recursively the values that are added removed or modified from file1.yaml to file2.yaml.
The values of data type such as lists are compared by the whole value (i.e.) must match exactly, but it is possible to refine the diff output by considering them unordered sets instead:
$ cat file1.yaml
a_key : a value
a_list:
- {id: 1, val: uno}
- {id: 2, val: dos}
- {id: 3, val: tres}
$ cat file2.yaml
a_key : another value
abother_key: some value
a_list:
- {id: 1, val: uno}
- {id: 2, val: dos}
- {id: 3, val: cuatro}
$ python yamldiff.py file1.yaml file2.yaml
# Added keys:
+ abother_key: some value
# Modified keys:
a_key:
- a value
+ another value
a_list:
- [{id: 1, val: uno}, {id: 2, val: dos}, {id: 3, val: tres}]
+ [{id: 1, val: uno}, {id: 2, val: dos}, {id: 3, val: cuatro}]
$ python yamldiff.py file1.yaml file2.yaml --set-keys a_list
# Added keys:
+ abother_key: some value
# Modified keys:
a_key:
- a value
+ another value
a_list:
# Removed keys:
- {id: 3, val: tres}
# Added keys:
+ {id: 3, val: cuatro}
It is also possible to treat list as key value pairs, by specifying the element of the list items to index on:
$ python yamldiff.py file1.yaml file2.yaml --set-keys a_list:id
# Added keys:
+ abother_key: some value
# Modified keys:
a_key:
- a value
+ another value
a_list:
# Modified keys:
# Matching:
{id: 3}
# Modified keys:
val:
- tres
+ cuatro
