property max_steps: int

Maximum number of steps an expression evaluation may take. When this is reached, evaluation stops with an error. Actual steps are an implementation detail.

 Methods

__init__(max_steps: int = 100000) → None

evaluate(expr: syside.Expression, stdlib: syside.Stdlib | None = None, scope: syside.Type | None = None) → tuple[syside.Value | None, syside.CompilationReport]

Evaluate expression. Note that custom functions and expressions, and most except a few standard library functions are not evaluatable. Constructor expressions evaluate as themselves because the constructor expressions conform to the constructed object implicitly. This primarily evaluates operator, metadata access, and feature reference expressions. If provided, stdlib is used to accelerate some common evaluations, e.g. checking for self expressions.

evaluate_feature(feature: syside.Feature, scope: syside.Type, stdlib: syside.Stdlib | None = None) → tuple[syside.Value | None, syside.CompilationReport]

Evaluate feature in scope, taking into account redefinitions. If feature is an Expression, this effectively performs evaluate.
