newfunction(:validate_re, :doc => <<-'ENDHEREDOC') do |args|
|
||
|
|
Perform simple validation of a string against a regular expression. The second
|
||
|
|
argument of the function should be a string regular expression (without the //'s)
|
||
|
|
or an array of regular expressions. If none of the regular expressions in the array
|
||
|
|
match the string passed in, then an exception will be raised.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
These strings validate against the regular expressions
|
||
|
|
|
||
|
|
validate_re('one', '^one$')
|
||
|
|
validate_re('one', [ '^one', '^two' ])
|
||
|
|
|
||
|
|
These strings do NOT validate
|
||
|
|
|
||
|
|
validate_re('one', [ '^two', '^three' ])
