hmm... i guess i forgot to paste in the rest of the code... here it is
in all its ugly gory:
cfset filename = rereplace(left(filename,
len(filename)-len(listlast(filename, .))-1), \W, , all) .
listlast(filename, .)
it may be eugh and ugly!, but it's a one-liner and takes care of .

So?
Unless you have a limited number of newlines, mindlessly shoving commands into
a single line is really dumb; it reduces readability and achieves nothing.
This is another thing that bugs me - people compressing code without thought -
having the right amount of
better then just do something like
rereplace(left(filename, len(filename)-len(listlast(filename, .)-1),
\W, , all)
Eugh. Ugly!
And doesn't restore the extension afterwards, so my-image-name.png would
become myimagename instead of myimagename.png.
My follow-up posted last night didn't show up. So, I'm re-doing it now.
Execellent, Peter, thank you very much.
I'll use
rereplace( FileName , '\W' , '' , 'all' )
On the extension stuff I have a way to address it.

Regular Expression gurus. How to use the REreplace function to remove special
characters including +, . in an image file name? The ReplaceList function
may miss some unexpected special characters for we don't know what sort of
special character may show up in a dynamically generated image
rereplace(foo, '[^\w]', '', 'all')
will replace any non-alphanumeric character in 'foo' (assuming 'foo' is the
file name).

Great. Thank you. I also found out that REreplace(str, [^a-zA-Z0-9],,all)
would achieve the same result but yours seems more elegant
rereplace(foo, '[^\w]', '', 'all')
will replace any non-alphanumeric character
No need to complicate things with an inverted character class.
\W is same as [^\w]
Also, this bugs me immensely:
assuming 'foo' is the file name
JUST USE THE VARIABLE FILENAME THEN!
So:
rereplace( FileName , '\W'

fair enough. good catch.

Hmmm, another thought...
Don, when you say image file name, is there a file extension to worry about
(i.e. jpg/png/etc)
If so, you'll want to be doing something like this...
rereplace( FileName , '(png|jpg|gif|tif|bmp)$' , '.\0' )
after the initial replacement, to restore the dot that will
I also found out that REreplace(str, [^a-zA-Z0-9],
,all)
would achieve the same result but yours seems more elegant (which
seems to say just keep {words}), my CF env = cf8 or cf81 for Windows,
does your solution have any dependency?
No dependency. \W [^\w] and [^a-zA-Z0-9] will all work
Sorry, typo. :(
In CFML/rereplace it is treated as [a-zA-Z0-9_] (not the underscore).
That should say note rather than not.
Underscore is included in \w (and excluded from \W) which is not what some
people might expect/want.
better then just do something like
rereplace(left(filename, len(filename)-len(listlast(filename, .)-1),
\W, , all)
