Naming Conversion

⁠

Snake caseLast edited: Wed, Aug 20, 2025 Snake case (sometimes stylized autologically as snake_case) is the naming convention in which each space is replaced with an underscore (_) character, and words are written in sentence case. It is a commonly used naming convention in computing, for example for variable and subroutine names, and for filenames. One study has found that readers can recognize snake case values more quickly than camel case. However, "subjects were trained mainly in the underscore style", so the possibility of bias cannot be eliminated. A variation is screaming snake case, where words are written in all caps (stylized as SCREAMING_SNAKE_CASE). This convention is used for constants in programming languages like C/C++, Python, Java, PHP, as well as for environment variables. See more en.wikipedia.org

Call user keyword

# call data

# ${data.id}

data:

- id: 1

age: 20

- id: 2

name: good jobs

age: 30

# call data

# ${data[0].age}

# ${data[${index}].age}

# It's work

data:

is_created: true # false

# It's now work

data:

is_created: Yes # No

ps. after that call ${data.is_created}, the value = true
