variable_dict_merge

Define a variable resulting of the merge of two other variables.

⚙️ Compatible targets: Linux, Windows

Parameters

Name	Documentation
prefix	The prefix of the variable name. This parameter is required.
name	The variable to define, the full name will be prefix.name. This parameter is required.
first_variable	The first variable, which content will be overridden in the resulting variable if necessary (written in the form prefix.name). This parameter is required.
second_variable	The second variable, which content will override the first in the resulting variable if necessary (written in the form prefix.name). This parameter is required.

Outcome conditions

You need to replace ${name} with its actual canonified value.

✅ Ok: variable_dict_merge_${name}_ok
- ☑️ Already compliant: variable_dict_merge_${name}_kept
- 🟨 Repaired: variable_dict_merge_${name}_repaired
❌ Error: variable_dict_merge_${name}_error

Example

method: variable_dict_merge
params:
  prefix: VALUE
  name: VALUE
  second_variable: VALUE
  first_variable: VALUE

Documentation

To use the generated variable, you must use the form ${prefix.name[key]} with each name replaced with the parameters of this method.

The resulting variable will be the merge of the two parameters, which means it is built by:

Taking the content of the first variable
Adding the content of the second variable, and replacing the keys that were already there

It is only a one-level merge, and the value of the first-level key will be completely replaced by the merge.

This method will fail if one of the variables is not defined. See variable_dict_merge_tolerant if you want to allow one of the variables not to be defined.

Usage

If you have a prefix.variable1 variable defined by:

{ "key1": "value1", "key2": "value2", "key3": { "keyx": "valuex" } }

And a prefix.variable2 variable defined by:

{ "key1": "different", "key3": "value3", "key4": "value4" }

And that you use:

variablr_dict_merge("prefix", "variable3, "prefix.variable1", "prefix.variable2")

You will get a prefix.variable3 variable containing:

{
  "key1": "different",
  "key2": "value2",
  "key3": "value3",
  "key4": "value4"
}
