Functions

func Parse added in v0.25.0 

func Parse(input string, parse func(*parser) (any, error), memoryGauge common.MemoryGauge) (result any, errors []error)

Parse creates a lexer to scan the given input string, and uses the given `parse` function to parse tokens into a result.

It can be composed with different parse functions to parse the input string into different results. See "ParseExpression", "ParseStatements" as examples.

func ParseArgumentList added in v0.25.0 

func ParseArgumentList(input string, memoryGauge common.MemoryGauge) (arguments ast.Arguments, errs []error)

func ParseDeclarations added in v0.25.0 

func ParseDeclarations(input string, memoryGauge common.MemoryGauge) (declarations []ast.Declaration, errs []error)

func ParseDocstringPragmaArguments added in v0.25.0 

func ParseDocstringPragmaArguments(docString string) []string

ParseDocstringPragmaArguments parses the docstring and returns the values of all pragma arguments declarations.

A pragma arguments declaration has the form `pragma arguments <argument-list>`, where <argument-list> is a Cadence argument list.

The validity of the argument list is NOT checked by this function.

func ParseDocstringPragmaSigners added in v0.25.0 

func ParseDocstringPragmaSigners(docString string) []string

ParseDocstringPragmaSigners parses the docstring and returns the values of all pragma signers declarations.

A pragma signers declaration has the form `pragma signers <signers-list>`, where <signers-list> is a list of strings.

The validity of the argument list is NOT checked by this function.
