Operators

Operators are a core part of the Blossom language, providing the building blocks for creating expressions, manipulating data and composing functions.

Arithmetic

These operators perform standard arithmetic calculations.

Operator	Description	Example
+	Addition	5 + 3
-	Subtraction	10 - 4
*	Multiplication	6 * 7
/	Division	15 / 3
%	Modulo (remainder)	17 % 5

For more complex operations, use the Math module.

Boolean

These operators perform boolean logic and comparisons.

Operator	Description	Example
&	Logical AND	True & True
|	Logical OR	True | False
!	Logical NOT	!False
==	Equality	10 == 10
!=	Inequality	5 != 7
>	Greater than	8 > 3
<	Less than	2 < 9
>=	Greater or equal to	6 >= 6
<=	Less or equal to	4 <= 5

Typing & Variables

These operators are used for type/variable declaration and assignment.

Operator	Description	Example
:	Type explicitation	name: String
=	Value assignment	x: Int = 10
:=	Type assignment	FloatList := List(Float)
:>	Schema assignment	Transformation :> (Int) : Int
&>	Type constraint	#constraints

Collections

This section covers operators related to collections (like lists, tuples or records).

Operator	Description	Example
...	Spread	newList: List(Int) = [...oldList, 4, 5]

Pattern matching

These operators are used for building pattern matching flows.

Element / Keyword	Description
match	Begins a pattern matching expression.
_	The wildcard pattern, matches any value. Used as the default case in match expressions.
if	Used to add conditions to patterns.
[ head | tail]	Matches the head & tail of a compatible collection type.

Pipeline

These operators are used for chaining function calls.

Operator	Description
|>	Pipeline operator. Passes the result of the left-hand expression to the right-hand function.
!>	Error-handling pipeline operator. Executes the following block only if the previous pipeline step results in an error.
