Function: match
|
|
|
|
--Usage--
|
|
> match(some_string, match: regular expression)
|
|
|
|
Does a string match the given [[type:regex|regular expression]]?
|
|
|
|
When the match is performed many times with the same regular expression it is more efficient to declare that as a default argument:
|
|
> my_match := match@(match: "something")
|
|
> my_match("input") # called many times
|
|
This way the regular expression is only compiled once.
|
|
|
|
