Overview ¶

Package relapse contains the relapse validation language and the functions necessary for running it. See katydid.github.io for the language documentation.

Index ¶

func Parse(relapse string) (*ast.Grammar, error)
func Prepare(g *ast.Grammar) (*mem.Mem, error)
func Validate(m *mem.Mem, p parser.Interface) (bool, error)

Functions ¶

func Parse ¶

func Parse(relapse string) (*ast.Grammar, error)

Parse parses the relapse string into an ast (abstract syntax tree)

func Prepare ¶

func Prepare(g *ast.Grammar) (*mem.Mem, error)

Prepare creates a memoizing object given the grammar. The memoizing object is used to memorize any previous states created from previous validations. This results in a more efficient execution each time the memoizing object is used to validate a parser.

func Validate ¶

func Validate(m *mem.Mem, p parser.Interface) (bool, error)

Validate validates the parser with the given memoizing object, containing the grammar, for efficiency.
