strings

Usage

local inspect = require("inspect")
local strings = require("strings")

-- strings.split(string, sep)
local result = strings.split("a b c d", " ")
print(inspect(result, {newline="", indent=""}))
-- Output: { "a", "b", "c", "d" }

-- strings.has_prefix(string, prefix)
local result = strings.has_prefix("abcd", "a")
-- Output: true

-- strings.has_suffix(string, suffix)
local result = strings.has_suffix("abcd", "d")
-- Output: true

-- strings.trim(string, cutset)
local result = strings.trim("abcd", "d")
-- Output: abc

-- strings.contains(string, substring)
local result = strings.contains("abcd", "d")
-- Output: true

Functions

func Contains

func Contains(L *lua.LState) int

Contains(): lua strings.contains(string, cutset) Port of go string.Contains() returns bool

Example

strings.contains(string, substring)

state := lua.NewState()
Preload(state)
source := `
    local strings = require("strings")
    local result = strings.contains("abcd", "d")
    print(result)
`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:

true

func HasPrefix

func HasPrefix(L *lua.LState) int

HasPrefix(): lua strings.has_prefix(string, suffix): port of go string.HasPrefix() return bool

Example

strings.has_prefix(string, prefix)

state := lua.NewState()
Preload(state)
source := `
    local strings = require("strings")
    local result = strings.has_prefix("abcd", "a")
    print(result)
`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:

true

func HasSuffix

func HasSuffix(L *lua.LState) int

HasSuffix(): lua strings.has_suffix(string, prefix): port of go string.HasSuffix() returns bool

Example

strings.has_suffix(string, suffix)

state := lua.NewState()
Preload(state)
source := `
    local strings = require("strings")
    local result = strings.has_suffix("abcd", "d")
    print(result)
`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:

true

func Loader

func Loader(L *lua.LState) int

Loader is the module loader function.

func Preload

func Preload(L *lua.LState)

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

local strings = require("strings")

func Split

func Split(L *lua.LState) int

Split(): lua strings.split(string, sep): port of go string.Split() returns table

Example

strings.split(string, sep)

state := lua.NewState()
Preload(state)
inspect.Preload(state)
source := `
    local inspect = require("inspect")
    local strings = require("strings")
    local result = strings.split("a b c d", " ")
    print(inspect(result, {newline="", indent=""}))
`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:

{ "a", "b", "c", "d" }

func Trim

func Trim(L *lua.LState) int

Trim(): lua strings.trim(string, cutset) Port of go string.Trim() returns string

Example

strings.trim(string, cutset)

state := lua.NewState()
Preload(state)
source := `
    local strings = require("strings")
    local result = strings.trim("abcd", "d")
    print(result)
`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:

abc

func TrimPrefix

func TrimPrefix(L *lua.LState) int

TrimPrefix(): lua strings.trim_prefix(string, cutset) Port of go string.TrimPrefix() returns string

Example

strings.trim_prefix(string, cutset)

state := lua.NewState()
Preload(state)
source := `
    local strings = require("strings")
    local result = strings.trim_prefix("abcd", "d")
    print(result)
`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:

abcd

func TrimSuffix

func TrimSuffix(L *lua.LState) int

TrimSuffix(): lua strings.trim_suffix(string, cutset) Port of go string.TrimSuffix() returns string

Example

strings.trim_suffix(string, cutset)

state := lua.NewState()
Preload(state)
source := `
    local strings = require("strings")
    local result = strings.trim_suffix("abcd", "d")
    print(result)
`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:

abc
