API Reference expression v2.33.1

Documentation for Expression, a library to parse and evaluate Floip compatible expressions

Extract @expression_doc attributes from modules defining callbacks and automatically write doctests for those.

Use this module to implement one's own callbacks. The standard callbacks available are implemented in Expression.Callbacks.Standard.

The function callbacks for the standard function set available in FLOIP expressions.

A helper module for creating a context that can be used with Expression.Eval

Expression.Eval is responsible for taking an abstract syntax tree (AST) as generated by Expression.Parser and evaluating it.

Expression.Parser is responsible for accepting a string containing an expression and returning the abstract syntax tree (AST) representing the expression.

A second attempt at the parser, hopefully a little easier to read & maintain.

Extract @expression_doc attributes from modules defining callbacks and automatically write doctests for those.

Use this module to implement one's own callbacks. The standard callbacks available are implemented in Expression.V2.Callbacks.Standard.

Callback functions to be used in Expressions.

Compatibility module to make the transition from V1 to V2 a bit easier, hopefully.

An compiler for AST returned by Expression.V2.Parser.

The context supplied to a function generated by Expression.V2.Compile.compile/1
