o23/n4

o23/n4 provides the ability to read pipeline and pipeline step configurations, currently supporting the YAML format. While reading the configuration, o23/n4 simplifies the notation of certain properties and also adds some related validation and script parsing supplements, as follows:

For single-line snippet, a prefix return will be automatically added to ensure that data can be returned,
Automatic conversion between camel case and kebab case property names,
If a property value starts with env:, it will be automatically replaced with the corresponding environment variable value,
The prefix env: supports multiple environment variables, separated by commas, with the first one having a value taking precedence.

When writing YAML configurations, the following syntax rules should also be noted:

null string value will be recognized as a null value. If you need to return a null value, you can write it as "null" or return null,
Property values that conform to JSON syntax will be automatically parsed. Therefore, if a value needs to be treated as a snippet, it should be enclosed in double quotation marks (""). For example, {name: $factor.name} can be written as "{name: $factor.name}",
Sometimes, we don't want the return prefix to be automatically added before a single-line snippet. In this case, we can use the vertical line | syntax to avoid this problem. For example, consider this:
```
snippet: $factor.enabled = true
```
If it is written in this way, the return value is true. We can instead write it as following:
```
snippet: |
  $factor.enabled = true
```

You can find all relevant YAML configuration examples in the server/02-api-test folder of o23/n99. Since the property names are self-explanatory, we will not explain the purpose of each property in the following section. You can refer to the documentation of o23/n3 for this part.
