Expressions in Midio allow you to write small snippets of logic directly inside function inputs. They can be used anywhere a function input is editable and are a powerful way to perform computations or dynamically construct values inline.
Expressions support many of the constructs you'd expect from a general-purpose language:
Unary and binary operators: Use operators like +, -, *, /, !, and more to perform arithmetic and logical operations.
Ternary operator: Use the condition ? valueIfTrue : valueIfFalse form to choose between values based on a condition.
Literals: You can use basic data literals including numbers (42), strings ("hello"), booleans (true, false), objects ({a: 1}), and lists ([1, 2, 3]).
Inputs: Add inputs to your expression by simply writing an identifier name (e.g., inputValue). This adds an additional input property underneath the input you placed the expression in.
Indexing and calls: Use [index] to access list or object properties and () to call functions. Note: Functions must currently be passed in as inputs to be called in expressions.
String interpolation: Embed expressions inside strings using ${...} syntax. For example: "Hello, ${name}!".
Use : Local variables can be retrieved by prefixing their name with @, e.g. @myVariable.
Expressions currently cannot be used directly inside object literals—this will be added in a future update. See the guide for more information about how you can work around this limitation for now.
