Robert,
I really was just trying to be humorous, not offensive. Sorry if it
came off that way.

WOW guys! This is awesome.
I could have googled it but in the past I have found that my
selection of keywords if poor as I don’t yet know the language to

So its just easier with my insane schedule to just ASK. I was
always taught that there is no such thing as a stupid question
except the one not asked...
So I asked.
This is all exciting news as now we have efficient info to study to
decide the best solution.
Charlie, Dean, I know Im a pain on here sometimes but I am really
trying to find my way. (or maybe Im just “trying” your patience.)
Either way THANKS TO ALL!
You guys (and gals) ROCK!

Subject: RE: [ACFUG Discuss] White Space In Source Code
Robert, there are many solutions, 3 specific tags, 2 tags with
related output control, one admin console setting, a new feature in
CFMX 7 that might be helpful, and a couple of approaches not
related to CFML. Pardon the few paragraphs to explain it all, but
each has difference nuances and indeed offers varying levels of
suppression and has slightly varying purpose (which reflect the
evolution of CFML over time).
First, there are 3 tags:
<cfprocessingdirective suppresswhitespace="Yes">
... do whatever
</cfprocessingdirective>
It's described as controlling "whether to suppress white space
characters within the cfprocessingdirective block that are
generated by CFML tags and often do not affect HTML appearance.
Does not affect any white space in HTML code.". That's its intent,
anyway. I think people have had varying experience, but I could be
wrong.
Note that with that tag you MUST offer a closing tag--and it has to
be in one template, can't be split with one in the application.cfm,
and the closing in the onrequestend.cfm. :-)
Still another tag is <CFSILENT></CFSILENT>. It's described as,
"Suppresses output produced by CFML within a tag’s scope. ". Again,
this is a paired tag and both must be in a single template (can't
be split up).
An older form is:
<cfsetting enablecfoutputonly="Yes">
which doesn't require a closing tag. With it, then the ONLY output
generated from the CFML page (including HTML tags and static text)
will be that placed within a CFOUTPUT statement. Again, even to
write out an html tag and/or static text, you'd need to wrap it (or
a big block of it) in a CFOUTPUT. This often confuses people,
either because they forget it's on and wonder, "where's my text"?
Or they turn it on intentionally and forget to wrap static text in
it and wonder, "why isn't this showing up?"
Note that if you want to turn it back on (or off, depending on how
you look at it), you use </cfsetting enablecfoutputonly="no">. And
note also that this CAN indeed be split over multiple files within
a request.
Another source of confusion with these approaches is the question
of whether they impact included files and custom tags. There are
differences between them in this regard, I'm pretty sure, and may
be differences in behavior regarding that between CF and BD, as
well as within different versions of each. Again, this stuff has
been evolving over time.
Still another way to control output, in CFCs (CFCOMPONENT) and CFC
methods and UDFs (using CFFUNCTION) is their available OUTPUT
attribute. OUTPUT="no/false" can also be used to prevent any output
being generated from the method, at all (again, even static text).
OUTPUT="yes/true" may not be obvious. It indicates that the body is
to act like it's all inside a CFOUTPUT, so you can drop in
references to variables for output and they are evaluated, again,
just as if within a CFOUTPUT tag. If you specify no OUTPUT
attribute at all, then things work like any normal CFML page.
Finally, there is also an Admin console setting to suppress
whitespace, which suppresses white space globally (all apps). Since
you can't too easily use CFSILENT and the CFPROCESSINGDIRECTIVE
variant in the application.cfm, it's another way folks try to
achieve suppression. Again, there are nuances, that are worth
exploring before you enable it, and I'll note also differences
between CF and BD in this regard.
Oh, a couple last ideas: if you want to take CFML out of the
picture, and just feel that CF pages in general generate too much
white space, you could also consider a Servlet Filter. They can
process page output after the request and could be used to remove
excessive whitespace. It's not trivial to do correctly, but there
are ones out there (from the Java world). I wrote about them in a
Feb 2003 CFDJ article, "Fun with Filters", at http://cfdj.sys-
con.com/read/41574.htm.
(Actually, that reminds me that in CFMX 7, you could also do
something like that (manually remove excessive whitespace) in the
new application.cfc onrequestend method.)
And last but not least, as John talked about at the ACFUG meeting,
you could also ask the web server to do gzip compression of all (or
some) pages. Note that this does not REMOVE the whitespace, but it
compresses the page so that during transfer from server to client
the penalty of it is lessened. It's worth noting that the
whitespace will still remain in the browser, and while browsers
generally ignore it, it still could impact the speed with which the
browser page loads (and possibly other behavior, since again the
whitespace is indeed still there.)
Hope that helps.

Is there a way to have CF output a page with no whitespace in the
source code?
