Regex

Synopsis

New ISL functions.

Syntax

• CreateRegex(regexSpec As String, Optional ignoreCase? As Boolean = true, Optional singleLine? As Boolean = true) As Any
• RegexMatch?(testString As String, regex As Any) As Boolean
  regex can be:

  • string - in that case regex ignores casing, and single line.
  • object created by CreateRegex()

Usage

In design :

Rule r As Any = createRegex("^[a-zA-Z0-9]\d{2}[a-zA-Z0-9](-\d{3}){2}[A-Za-z0-9]$")

In Immediate window:

Intent >RegexMatch?("0919-2893-1256", r)
--> False
Intent >RegexMatch?("A08Z-931-468A", r)
--> True

Or simplified:

Intent >RegexMatch?("_A90-123-129X", "^[a-zA-Z0-9]\d{2}[a-zA-Z0-9](-\d{3}){2}[A-Za-z0-9]$")
--> False 

For case sensitive regex matching:

Rule r As Any = createRegex("^a", ignoreCase? := False)
 
Intent >RegexMatch?("A", r)
--> False
