regexp 
Usage
local regexp = require("regexp")
local inspect = require("inspect")
-- regexp.match(regexp, data)
local result, err = regexp.match("hello", "hello world")
if err then error(err) end
if not(result==true) then error("regexp.match()") end
-- regexp.find_all_string_submatch(regexp, data)
local result, err = regexp.find_all_string_submatch("string: '(.*)\\s+(.*)'$", "my string: 'hello world'")
if err then error(err) end
if not(result[1][2] == "hello") then error("not found: "..tostring(result[1][2])) end
if not(result[1][3] == "world") then error("not found: "..tostring(result[1][3])) end
-- regexp:match()
local reg, err = regexp.compile("hello")
if err then error(err) end
local result = reg:match("string: 'hello world'")
if not(result==true) then error("regexp:match()") end
-- regexp:find_all_string_submatch()
local reg, err = regexp.compile("string: '(.*)\\s+(.*)'$")
if err then error(err) end
local result = reg:find_all_string_submatch("string: 'hello world'")
local result = inspect(result, {newline="", indent=""})
if not(result == [[{ { "string: 'hello world'", "hello", "world" } }]]) then error("regexp:find_all_string_submatch()") end
-- regexp.find_all_string_submatch(regexp, data)
local result, err = regexp.find_all_string_submatch("string: '(.*)\\s+(.*)'$", "my string: 'hello world'")
if err then error(err) end
if not(result[1][2] == "hello") then error("not found: "..tostring(result[1][2])) end
if not(result[1][3] == "world") then error("not found: "..tostring(result[1][3])) end

Functions ¶
func FindAllStringSubmatch ¶
regexp_ud:find_all_string_submatch(string) returns table of table of strings
Example ¶
regexp_ud:find_all_string_submatch(string)
state := lua.NewState()
Preload(state)
inspect.Preload(state)
source := `
local regexp = require("regexp")
local inspect = require("inspect")
local reg, err = regexp.compile("string: '(.*)\\s+(.*)'$")
if err then error(err) end
local result = reg:find_all_string_submatch("string: 'hello world'")
print(inspect(result, {newline="", indent=""}))
`
if err := state.DoString(source); err != nil {
log.Fatal(err.Error())
}
Output: { { "string: 'hello world'", "hello", "world" } }
func Match ¶
regexp_ud:match(string) returns bool
Example ¶
regexp_ud:match(string)
state := lua.NewState()
Preload(state)
source := `
local regexp = require("regexp")
local reg, err = regexp.compile("hello")
if err then error(err) end
local result = reg:match("string: 'hello world'")
print(result)
`
if err := state.DoString(source); err != nil {
log.Fatal(err.Error())
}
Output: true
func Preload ¶
Preload adds regexp to the given Lua state's package.preload table. After it has been preloaded, it can be loaded using require:
local regexp = require("regexp")
func SimpleFindAllStringSubmatch ¶
regexp.find_all_string_submatch(regular expression string, string) returns (table of table strings, error)
func SimpleMatch ¶
regexp.match(regular expression string, string) returns (bool, error)
