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
Reader/Writer classes often used with json+yaml Encoder/Decoder
reader = strings.new_reader([[{"foo":"bar","baz":"buz"}]])
assert(reader:read("*a") == [[{"foo":"bar","baz":"buz"}]])
writer = strings.new_builder()
writer:write("foo", "bar", 123)
assert(writer:string() == "foobar123")

Functions ¶
func CheckStringsBuilder ¶ added in v0.1.6
func CheckStringsReader ¶ added in v0.1.6
func Contains ¶
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 Fields ¶
Fields lua strings.fields(string) Port of go string.Fields() returns table
Example ¶
strings.fields(string)
state := lua.NewState()
Preload(state)
inspect.Preload(state)
source := `
local strings = require("strings")
local result = strings.fields("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 HasPrefix ¶
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 ¶
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 LVStringsBuilder ¶ added in v0.1.6
func LVStringsReader ¶ added in v0.1.6
func Preload ¶
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 ¶
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 ¶
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 ¶
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 ¶
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
