eManager
provides the following shorthand for writing complicated regular expressions.
eManager will pre-process expressions and translate the shorthand into
regular expressions.
For example, {D}+ would be translated
to [0-9]+. If a shorthand expression is enclosed in brackets (example:
{}) or double-quotes, then IMSS will
not translate that shorthand expression to a regular expression.
| Shorthand | Description |
| {D} | [0-9] |
| {L} | [A-Za-z] |
| {SP} | [(),;\.\\<>@\[\]:] |
| {NUMBER} | [0-9]+ |
| {WORD} | [A-Za-z]+ |
| {CR} | \r |
| {LF} | \n |
| {LWSP} | [ \t] |
| {CRLF} | (\r\n) |
| {WSP} | [ \t\f]+ |
| {ALLC} | . |
eManager also provides the following meta-symbols.
The difference between shorthand and meta-symbols is that meta-symbols
can be within a bracket expression.
| Meta-symbol | Description |
| \s | [[:space:]] |
| \S | [^[:space:]] |
| \d | [[:digit:]] |
| \D | [^[:digit:]] |
| \w | [_[:alnum:]] |
| \W | [^_[:alnum:]] |
