Classes

The only responsibility of the InterpreterContext class is to store variables, and keep them during the execution, where multiple expressions might use the same set of variables.

Keyword instances are used to provide static points in match sequences so that they can be used as pillars of the expressions the developer tries to match

A special subclass of the Keyword class, which initialises a Keyword with an opening type. Usually used for opening parentheses: OpenKeyword("[")

A special subclass of the Keyword class, which initialises a Keyword with an closing type. Usually used for closing parentheses: CloseKeyword("]")

Generic superclass of Variables which are aware of their Interpreter classes, as they use it when mapping their values

This interpreter is used to evaluate string expressions and return a transformed string, replacing the content where it matches certain patterns. Typically used in web applications, where the rendering of an HTML page is provided as a template, and the application replaces certain statements, based on input parameters.

A special kind of variable that is used in case of StringTemplateInterpreters. It does not convert its content using the interpreterForEvaluatingVariables but always uses the StringTemplateInterpreter instance. It’s perfect for expressions, that have a body, that needs to be further interpreted, such as an if or while statement.

A type of interpreter implementation that is capable of evaluating arbitrary string expressions to strongly typed variables

The implementation of a DataType uses the DataTypeProtocol to convert input to a strongly typed data and print it if needed

Literals are used by DataTypes to be able to recognise static values, that can be expressed as a given type

Functions can process values in given DataTypes, allowing the expressions to be feature-rich

Variable represents a named placeholder, so when the matcher recognises a pattern, the values of the variables are passed to them in a block.

A processor that can process a raw value with extra information, such as interpreter and context

This class provides the main logic of the Eval framework, performing the pattern matching details

Pattern consists of array of elements
