Functions ¶

func FnMatch ¶

func FnMatch(typ *types.Type, fns []*types.FuncValue) (int, error)

FnMatch is run to turn a polymorphic, undetermined list of functions, into a specific statically typed version. It is usually run after Unify completes. It returns the index of the matched function.

func HasDuplicateTypes ¶

func HasDuplicateTypes(typs []*types.Type) error

HasDuplicateTypes returns an error if the list of types is not unique.

func ParseImportName ¶

func ParseImportName(name string) (*interfaces.ImportData, error)

ParseImportName parses an import name and returns the default namespace name that should be used with it. For example, if the import name was: "git://example.com/purpleidea/Module-Name", this might return an alias of "module_name". It also returns a bunch of other data about the parsed import. TODO: check for invalid or unwanted special characters

func ValidateVarName ¶

func ValidateVarName(name string) error

ValidateVarName returns an error if the string pattern does not match the format for a valid variable name. The leading dollar sign must not be passed in.
