base64

Lua module for encoding/base64

Usage

Encoding

local base64 = require("base64")

s = base64.RawStdEncoding:encode_to_string("foo\01bar")
print(s)
Zm9vAWJhcg

s = base64.StdEncoding:encode_to_string("foo\01bar")
print(s)
Zm9vAWJhcg==

s = base64.RawURLEncoding:encode_to_string("this is a <tag> and should be encoded")
print(s)
dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA

s = base64.URLEncoding:encode_to_string("this is a <tag> and should be encoded")
print(s)
dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA==

Decoding

local base64 = require("base64")

s, err = base64.RawStdEncoding:decode_string("Zm9vAWJhcg")
assert(not err, err)
print(s)
foobar

s, err = base64.StdEncoding:decode_string("Zm9vAWJhcg==")
assert(not err, err)
print(s)
foobar

s, err = base64.RawURLEncoding:decode_string("dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA")
assert(not err, err)
print(s)
this is a <tag> and should be encoded

s, err = base64.URLEncoding:decode_string("dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA==")
assert(not err, err)
print(s)
this is a <tag> and should be encoded

Functions ¶

func CheckBase64Encoding ¶

func CheckBase64Encoding(L *lua.LState, n int) *base64.Encoding

CheckBase64Encoding checks the argument at position n is a *base64.Encoding

func DecodeString ¶

func DecodeString(L *lua.LState) int

DecodeString decodes the encoded string with the encoding

Example ¶

state := lua.NewState()
defer state.Close()
Preload(state)
source := `
    local base64 = require("base64")
	s, err = base64.RawStdEncoding:decode_string("Zm9vAWJhcg")
	assert(not err, err)
	print(s)

	s, err = base64.StdEncoding:decode_string("Zm9vAWJhcg==")
	assert(not err, err)
	print(s)

	s, err = base64.RawURLEncoding:decode_string("dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA")
	assert(not err, err)
	print(s)

	s, err = base64.URLEncoding:decode_string("dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA==")
	assert(not err, err)
	print(s)

`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:
foo�bar
foo�bar
this is a <tag> and should be encoded
this is a <tag> and should be encoded

func EncodeToString ¶

func EncodeToString(L *lua.LState) int

EncodeToString decodes the string with the encoding

Example ¶

state := lua.NewState()
defer state.Close()
Preload(state)
source := `
    local base64 = require("base64")
	s = base64.RawStdEncoding:encode_to_string("foo\01bar")
	print(s)

	s = base64.StdEncoding:encode_to_string("foo\01bar")
	print(s)

	s = base64.RawURLEncoding:encode_to_string("this is a <tag> and should be encoded")
	print(s)

	s = base64.URLEncoding:encode_to_string("this is a <tag> and should be encoded")
	print(s)

`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:
Zm9vAWJhcg
Zm9vAWJhcg==
dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA
dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA==

func LVBase64Decoder ¶

func LVBase64Decoder(L *lua.LState, reader io.Reader) lua.LValue

func LVBase64Encoder ¶

func LVBase64Encoder(L *lua.LState, writer io.Writer) lua.LValue

func LVBase64Encoding ¶

func LVBase64Encoding(L *lua.LState, encoding *base64.Encoding) lua.LValue

LVBase64Encoding converts encoding to a UserData type for lua

func Loader ¶

func Loader(L *lua.LState) int

Loader is the module loader function.

func NewDecoder ¶

func NewDecoder(L *lua.LState) int

func NewEncoder ¶

func NewEncoder(L *lua.LState) int

func NewEncoding ¶

func NewEncoding(L *lua.LState) int

func Preload ¶

func Preload(L *lua.LState)

Preload adds yaml to the given Lua state's package.preload table. After it has been preloaded, it can be loaded using require:

local yaml = require("yaml")
