Traditionally SREs have had the following aliases
allowing the user to choose between brevity and
self-description:
From SCSH:
| or
& and
: seq
From IrRegex (in this case introducing a new short form):
$ submatch
=> submatch-named
For consistency Michael Montague suggested all
SREs have a short and long form. John Cowan
suggests the following names:
? optional
* zero-or-more
+ one-or-more
>= at-least
= exactly
** repeated
?? non-greedy-optional
*? non-greedy-zero-or-more
**? non-greedy-repeated
For the cset-sres we'd also need:
/ char-range (or cset-range?)
- difference (or diff?)
~ complement (or not?)
I would suggest not introducing new short forms
of existing long names. Comments welcome, but
if there are no objections I'll go with this.
