## Regular Expressions for the JavaScript target.
## * https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions
runnableExamples:
let jsregex: RegExp = newRegExp(r"\s+", r"i")
jsregex.compile(r"\w+", r"i")
doAssert jsregex.test(r"nim javascript")
doAssert jsregex.exec(r"nim javascript") == @["nim".cstring]
doAssert jsregex.toString() == r"/\w+/i"
jsregex.compile(r"[0-9]", r"i")
doAssert jsregex.test(r"0123456789abcd")
when not defined(js) and not defined(Nimdoc):
{.error: "This module only works on the JavaScript platform".}
type RegExp* {.importjs.} = object ## Regular Expressions for JavaScript target.
flags* {.importjs.}: cstring ## cstring that contains the flags of the RegExp object.
dotAll* {.importjs.}: bool ## Whether `.` matches newlines or not.
global* {.importjs.}: bool ## Whether to test against all possible matches in a string, or only against the first.
ignoreCase* {.importjs.}: bool ## Whether to ignore case while attempting a match in a string.
multiline* {.importjs.}: bool ## Whether to search in strings across multiple lines.
source* {.importjs.}: cstring ## The text of the pattern.
sticky* {.importjs.}: bool ## Whether the search is sticky.
unicode* {.importjs.}: bool ## Whether Unicode features are enabled.
lastIndex* {.importjs.}: cint ## Index at which to start the next match (read/write property).
input* {.importjs.}: cstring ## Read-only and modified on successful match.
lastMatch* {.importjs.}: cstring ## Ditto.
lastParen* {.importjs.}: cstring ## Ditto.
leftContext* {.importjs.}: cstring ## Ditto.
rightContext* {.importjs.}: cstring ## Ditto.
func newRegExp*(pattern: cstring; flags: cstring): RegExp {.importjs: "new RegExp(@)".}
## Creates a new RegExp object.
func compile*(self: RegExp; pattern: cstring; flags: cstring) {.importjs: "#.compile(@)".}
## Recompiles a regular expression during execution of a script.
func exec*(self: RegExp; pattern: cstring): seq[cstring] {.importjs: "#.exec(#)".}
## Executes a search for a match in its string parameter.
func test*(self: RegExp; pattern: cstring): bool {.importjs: "#.test(#)".}
## Tests for a match in its string parameter.
func toString*(self: RegExp): cstring {.importjs: "#.toString()".}
## Returns a string representing the RegExp object.
