Yep, makes sense.
I'll make the change.
Im thinking:
wrap(operand, string_to_wrap_around_it, boolean_ignore_if_already_present)
escape(operand, string_to_find, string_to_escape_it_with)
Does this capture the essence?
Your escape function is identical to the replace function. What do you do if the
boolean is false? (i.e. don't ignore if already present)
I was thinking something like:
wrap(operand, string_to_wrap_around_it, string_to_escape_it_with)
if string_to_escape_it_with is not null, replace any occurances of the wrap
string in the middle with the escape string.
If the third parameter is not provided or is null, don't look for anything in
the middle.

As a thought, for wrap, I would suggest adding an optional third
parameter, namely what to use if the string_to_wrap_around_it already
appears in the string. I'm thinking along the lines of quoting a string and
dealing with quotes in the middle of it, but any time you put delimeters
around a string, there is a really good chance that you don't want that
string to appear in the middle of it (unless the wrapping is purely for
human consumption)

Hi,
Have added 3 functions to rainerscript:
- replace(operand, substring_to_be_replaced, its_replacement)
- wrap(operand, string_to_wrap_around_it)
- concat(operand_1, operand_2)
Examples:
replace("foo bar baz", "ba", "BA") => "foo BAr BAz"
concat("foo", "bar") => "foobar"
wrap("hello", "__") => "__hello__"
replace("foo bar", concat("b", "ar"), wrap("baz", "*")) => "foo *baz*"
I felt the need for this while working on some unstructured -> structured
transformation of log-messages. Searched the forums a little, for
instance:
http://kb.monitorware.com/modify-message-string-strip-
addresses-from-logs-t1610.html
and found that nothing equivalent existed, hence the patch.
0001-... has replace and wrap impl
0002-... has concat impl
(the patches go in the same order)
Im currently running an large installation with these patches applied over
8.4.0, they seem to be working fine.
If the patches look good for merging, I'll be happy to update the
documentation(actually don't know how to update doc yet, will have to dig
in to learn more about it).
