Regular expression

Regex is used in 2 places:

- for the pattern validation of strings

- for the definition of pattern fields

These regular expressions should be valid according to the ECMA 262 regular expression dialect.  Regex value should start with the “^” and end with the “$” anchors to satisfy the internal Hackolade validation.

The following regular expression tokens are supported:

• simple character classes ([abc]), range character classes ([a-z]);
• complemented character classes ([^abc], [^a-z]);
• simple quantifiers: "+" (one or more), "*" (zero or more), "?" (zero or one), and their lazy versions ("+?", "*?", "??");
• range quantifiers: "{x}" (exactly x occurrences), "{x,y}" (at least x, at most y, occurrences), {x,} (x occurrences or more), and their lazy versions;
• simple grouping ("(...)") and alternation ("|").
