Functions

func FileExists

func FileExists(ctx context.Context, file string) (bool, error)

FileExists returns true if a file is existing. This is meant to be used with SourceFs related operations.

func IsTerminal

func IsTerminal() bool

func SetArgs

func SetArgs(c *cli.Context)

SetArgs set context arguments, for example command line `arrai -d r file.arrai arg1 arg2 arg3` will save `file.arrai arg1 arg2 arg3` as a slice to Arguments.

func ValueAsBytes

func ValueAsBytes(v rel.Value) ([]byte, bool)

ValueAsBytes transform rel.Value to byte array. In arr.ai, all empty sets are the same and `""`, `{}` and `[]` will be parsed to rel.GenericSet.

func ValueAsString

func ValueAsString(v rel.Value) (string, bool)

ValueAsString transform rel.Value to string. In arr.ai, all empty sets are the same and `""`, `{}` and `[]` will be parsed to rel.GenericSet.

func ValueTypeAsString

func ValueTypeAsString(v rel.Value) string

ValueTypeAsString returns a string that describes the type of the value in a human-readable form.
