hex 
Lua module for encoding/hex
Usage
Encoding
local hex = require("hex")
s = hex.RawStdEncoding:encode_to_string("foo\01bar")
print(s)
Zm9vAWJhcg
s = hex.StdEncoding:encode_to_string("foo\01bar")
print(s)
Zm9vAWJhcg==
s = hex.RawURLEncoding:encode_to_string("this is a <tag> and should be encoded")
print(s)
dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA
s = hex.URLEncoding:encode_to_string("this is a <tag> and should be encoded")
print(s)
dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA==
Decoding
local hex = require 'hex'
decoded, err = hex.decode_string("666f6f62617262617a")
assert(not err, err)
print(decoded)
foobar
encoded = hex.encode_to_string(decoded)
print(encoded)

Functions ¶
func DecodeString ¶
DecodeString decodes the encoded string with the encoding
Example ¶
state := lua.NewState()
defer state.Close()
Preload(state)
source := `
local hex = require 'hex'
s, err = hex.decode_string("666f6f01626172")
assert(not err, err)
print(s)
`
if err := state.DoString(source); err != nil {
log.Fatal(err.Error())
}
Output: foo�bar
func EncodeToString ¶
EncodeToString decodes the string with the encoding
Example ¶
state := lua.NewState()
defer state.Close()
Preload(state)
source := `
local hex = require 'hex'
s = hex.encode_to_string("foo\01bar")
print(s)
`
if err := state.DoString(source); err != nil {
log.Fatal(err.Error())
}
Output: 666f6f01626172
func LVHexDecoder ¶
LVHexDecoder creates a new Lua user data for the hex decoder
func LVHexEncoder ¶
LVHexEncoder creates a new Lua user data for the hex encoder
func NewDecoder ¶
Example ¶
state := lua.NewState()
defer state.Close()
Preload(state)
strings.Preload(state)
source := `
local hex = require 'hex'
local strings = require 'strings'
local reader = strings.new_reader('666f6f01626172')
decoder = hex.new_decoder(reader)
local s = decoder:read("*a")
print(s)
`
if err := state.DoString(source); err != nil {
log.Fatal(err.Error())
}
Output: foo�bar
func NewEncoder ¶
Example ¶
state := lua.NewState()
defer state.Close()
Preload(state)
strings.Preload(state)
source := `
local hex = require 'hex'
local strings = require 'strings'
local writer = strings.new_builder()
encoder = hex.new_encoder(writer)
encoder:write("foo\01bar")
print(writer:string())
`
if err := state.DoString(source); err != nil {
log.Fatal(err.Error())
}
Output: 666f6f01626172
