class Mint::Scope

• Mint::Scope
• Reference
• Object

Overview

The class is responsible for keeping track of which variable is pointing to which node.

The data strucutre is a tree where leafs are the levels of the child nodes of an AST node and a level is a container for the possible targets.

When resolving a variable we travese it's tree upwards to find the target which matches the value of the variable.

Defined in:

scope.cr

• .new(ast : Ast)

Instance Method Summary

• #add(node : Ast::Node, key : String, value : Ast::Node)

  Adds a target to the level of the given node.

• #build(node : Ast::Node | Nil, parent : Ast::Node)
• #build(nodes : Array(Ast::Node), parent : Ast::Node, *, stack : Bool = false)

  Builds an array of nodes.

• #build(node : Ast::Node)

  Builds the scope for the given node and it's child nodes.

• #create(node : Ast::Node, parent : Ast::Node | Nil = nil)

  Builds a level for the node and yields the parents scope.

• #nodes : Hash(Mint::Ast::Node, Mint::Scope::Level)

  We track the level of a node in here.

• #resolve(target : String, base : Ast::Node)
• #resolve(node : Ast::Variable)

  Tries to find the target of the given variable.

• #resolve

  Resolves the targets which can be statically resolved, currently only the exposed variables of a connected store in a component.

• #root : Mint::Scope::Level
• #scopes : Hash(Mint::Ast::Node, Array(Mint::Scope::Level))

  We track the level stack of a node in here.
