Scalar parsing library

Scalar is a library for parsing strings into arbitrary scalars (integers, floats, strings, booleans, etc). It is helpful for tasks such as parsing strings passed as environment variables or command line arguments.

go get github.com/alexflint/go-scalar

The main API works as follows:

var value int
err := scalar.Parse(&value, "123")

There is also a variant that takes a reflect.Value:

var value int
err := scalar.ParseValue(reflect.ValueOf(&value), "123")

Functions

func CanParse

func CanParse(t reflect.Type) bool

CanParse returns true if the type can be parsed from a string.

func Parse

func Parse(dest interface{}, s string) error

Parse assigns a value to v by parsing s.

func ParseValue

func ParseValue(v reflect.Value, s string) error

ParseValue assigns a value to v by parsing s.
