Re: More Complicated RegEx Replace
This is the replace statement a regex guru gave me
to wrap a variable found in a string in a span tag.
Not sure you can call them a guru when the only piece of regex used is a pair
of parentheses which are entirely unnecessary. *shrug*
Here's a simpler version that does exactly the same thing:
REReplaceNoCase
( answer
, search_string
, 'span class=keyword\0/span'
, 'all'
)
However, what that isn't doing is escaping potential regex metacharacters
inside search_string (which could then result in unexpected behaviour).
If you can't guarantee there will not be any metacharacters present, you need
to do this:
REReplaceNoCase
( answer
, search_string.replaceAll('[$^*()+\[\]{}.?\\|]','\\$0')
, 'span class=keyword\0/span'
, 'all'
)
(Which prefixes the relevant characters with a backslash to escape them.)
Anyhow, as for your actual problem, regex is not a good tool for parsing HTML
(which is what you're asking to be done by excluding tag attributes from
matching).
What you need to do is use a HTML parsing library, such as jSoup, to isolate
the text segments within HTML tags, and loop through performing your replace
operation on each of those in turn (recursing down through any child tags as
required).
Using jSoup, this can be achieved with the textNodes() method, to access the
individual segments of text and child nodes:
http://jsoup.org/apidocs/org/jsoup/nodes/Element.html#textNodes()
If you're unfamiliar with using JARs in CF, Ben Nadel has a post on using jSoup
with CF10:

Re: Replace Question
This is a case for Regular Expressions (RegEx):
REReplaceNoCase(answer, '(#search_string#)', 'span
class=keyword\1/span', 'all')#
Heh, just seen this after the other thread, so guess I'll repeat what I said
there:
Using parentheses is completely unnecessary. Use \0 in the replacement string
instead.
If search_string is (for example) $10 or :) or a+b^c or whatever then
simply using it as a regex_pattern will cause problems.
To solve this means escaping the meta-characters, for example,
search_string.replaceAll('[$^*()+\[\]{}.?\\|]','\\$0')
Putting both those together results in:
REReplaceNoCase
( answer
, search_string.replaceAll('[$^*()+\[\]{}.?\\|]','\\$0')
, 'span class=keyword\0/span'
, 'all'
)
(Though of course, as noted in the other thread, this doesn't deal with HTML.)

Re: Check for list of words in string
Wouldn't this also catch words like 'myselection'? Yes. \b is your friend. :) Or possibly even stuff like (?=^|;)\s*(?:SELECT|DECLARE|EXEC|etc)\b to ensure this is stuff at a beginning of a string/statement. But I don't really agree with the general approach here. With cfqueryparam + thorough code reviews + security testing both before and after code goes live, you don't need to worry about this.

Re: Anyone care to review this image handling process?
I'd raise four must-fix issues with that code. 1: You haven't var/local scoped any of these variables, despite being inside a function which is probably going to end up in a shared scope, so this code isn't thread-safe and thus can cause incorrect behaviour if two people upload images at the same time. (Or, possibly, you've not copied that part of code, since there's no cffunction/cfargument lines either, but still safer to highlight the problem.) 2: The variable loopCounter never changes, which is probably not what you want. The whole imageList looping is broken, because the list attribute accepts a string (which is actually what you're giving it, so no errors), but the imageList variable is a query. Either do list=#ValueList(imageList.name)# or use query=imageList instead. (Also, don't forget the filter attribute. You can use it to do file* as well as *.ext to reduce the number of files to check against) 3: You've also got incorrect hash usage, e.g: cfset newImageFileName = reReplace(#originalImageFileName#, '[^a-zA-Z0-9_\-.]', '', 'all') / cfif image is '#newFileNameComplete#' cfset renamedNewFileNameComplete = #newFileNameComplete# (Yes, over-use of hashes is a must-fix issue, because it indicates a lack of understanding of what's going on, so it's a bug in the programmers brain that needs fixing.) 4: As Justin points out, tempImages is going to keep growing. Depending on where the images are uploaded from, you may simply be able to FileDelete the uploaded version after the cfimage/resize has been done, and that's that. Or you could schedule a task that runs outside working hours to clear the folder, or to remove anything over X days old (if there's a reason to keep recent ones). I wouldn't pass any code without those things being corrected, but a few others which aren't specific bugs but still worth being mentioned/fixed are: 5: You haven't use a variable for e:\tempImages, which means you'd need to search/replace if/when the drive or path changes. Better to have it defined in one place, so you can simply change a single line if it does, and using a variable means any typo will be caught (whereas a typo in a directory name might be silently accepted). 6: I'd also point out that you've got an awful lot of single-use variables there. Variables are variable. You can change what they contain and don't need to keep creating new ones - you only need one or two ImageFileName variables there, which you mutate as you go through the code. 7: Based on all this being inside if/len/trim, I'm thinking this is just a small part of a larger function, dealing with profile changing (or something like that). If so, I definitely suggest breaking down the function into smaller self-contained sub-functions. i.e. This logic should in be a processStaffPhoto function, with relevant arguments being passed in and the final filename being returned at the end, called by whatever the larger function is. Makes things significantly easier to follow and maintain. There we go... happy to expand on anything here if you want more details. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:346894 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

Re: cffunction - initialize query as empty string or QueryNew
It doesn't matter - CFML is not like Java (where you must pre-define variables with strict types). In CFML, variables can change types at any time. If you're just var scoping a cfquery variable, it doesn't matter what you use. (I would guess using QueryNew might be ever so slightly slower - but I doubt it's significant, and wouldn't be surprised if the JVM optimized it away anyhow.) You can avoid the pointless debate by using: cfquery name=local.myQuery etc If you're not on CF9/equivalent then you need a cfset var local = StructNew() / immediately after any arguments. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:346488 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

Re: Committing Line by Line Changes?
As has been said, Git was built knowing that branching is an important task - and so creating and using branches is easy, fast, and flexible. (I used to work on a large project that used SVN, and I had half a dozen checked-out copies because I often worked on multiple things and switching branches with SVN was so slow.) I very much recommend the branching strategy Jonah linked to ( http://nvie.com/posts/a-successful-git-branching-model/ ), it might seem like overkill, but it really does make sense. I'm also going to repeat a couple of things that have already been said, because I think it's beneficial to say them in a different way. :) Git allows you to move all uncommitted changes to a temporary branch, and to retrieve again later, using git stash command. Also, if you want to, you can convert stashes into real branches (with a single command). See http://www.kernel.org/pub/software/scm/git/docs/git-stash.html for info. Git allows changes to be staged in parts with git add --patch filename - this will step you through a list of changes in that file, and allows you to indicate if each change should be staged or not, as well as splitting each one into smaller changes. I do this all the time, when I've got multiple unrelated changed that each deserve independent commit messages. Once you understand what's happening, it's not hard to handle. (Unless the changes are not unrelated, but that's a different problem.) Details at http://kernel.org/pub/software/scm/git/docs/git-add.html Also worth pointing out, aside from those man pages, there's a number of good documentation sources for git: http://www.kernel.org/pub/software/scm/git/docs/user-manual.html http://progit.org/book (also available as a physical book) http://book.git-scm.com ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:346378 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

Re: Need some perspective...
I'm doing a lot of detection and loading code and style sheets based on what browser is being used, but it's a steady pain to keep up with what works and what doesn't. That's why you shouldn't do browser detection, you should do feature detection. For HTML5, here's a guide to doing that: http://diveintohtml5.org/detect.html When I get really grumpy, my urge is to just feed a text based site to anyone using IE with a note at the top that says if you want to see the pretty stuff, get a real browser. Again, with sensible feature detection you will return a site that is as pretty as IE can handle, but without the extra frills. Ultimately, *any* browser with all scripts/styles/images/etc disabled should receive a usable text-based site.

If you want a more filter-based approach, you want to use something that is built around filtering, which (I think) is one of the main benefits of CouchDB and similar.

Re: Need some perspective...
I don't quite see it that way, Peter. ... It's been a long week... And a long rambling post, which seems to be missing the points I was making. :P The W3C will always be doing the major milestone nonsense, because they're a big bureaucratic organisation that does stuff like that. That's *why* the WHATWG was created and ditched all the XHTML nonsense. Oh, and there's a reason the WHATWG was founded by Mozilla, Opera, and WebKit. The browser vendors *don't* have an interest in HTML incompatibilities - there's no benefit to it, and it's not how they're marketing themselves. If they were making money from browsers then they might fix it all sooner, but at least we are converging towards it, and it's a good thing people don't need to pay money to get better browsers. Just because SitePoint are crap at doing books/tutorials/titles/whatever doesn't mean that HTML5 and CSS3 can't be used. Even if it all doesn't work in IE9, it doesn't matter - you don't care what works in which browsers! You do feature detection so users with most advanced browsers have the best experience, and everyone else has a good enough experience. Of course, if a particular feature will take time to implement, it's worth checking who currently/soon supports it, to make sure the work isn't a waste of time because nobody can use it ( see http://caniuse.com ), but on the whole stop worrying about supporting particular browser versions. Mobiles add small screens, zooming, and rotating screens to the mix, but beyond that they're not really bringing anything new. And there's no reason why you can't have a distinct mobile site, if your main site has features which don't translate well. Anyway, if it has been a long week you should stop worrying about all this and relax a bit - that's exactly what weekends were designed for. ;) ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:345693 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: Problem with pound signs
well any variable has to be #text# with no spaces No it doesn't. If you felt like it, you could do... # text # That is perfectly valid and works on all the CFML engines. However, even if a valid assumption for the codebase in question, trying to match a hash followed by spaces would results in matching... #text# this #text# Which is obviously not desired. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:345617 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: Problem with pound signs
I would start by finding/escaping identifiable single hashes - i.e. the font
colours and HTML entities.
Using a regex search that supports lookbehind (so not CF itself, but ok with
CFEclipse/CFBuilder) you can do:
(?!#)#(?=[A-F0-9]{3,6}\s*+[';])
Which assumes colours must end with or ' or ; which I think covers both HTML
attributes and CSS use.
For HTML entities:
(?=)#(?=\d+;|x[A-F0-9]+;)
Oh and # parts in links... something like:
(?=\.(ht|cf)ml?)#(?=[^#']++['])
Those three are all written to just match the # itself, so you can replace with
## and it should work. (Obviously make sure you have a backup of the code
before changing anything though.)
Once all the known single hashes are escaped, I'd just attempt to compile all
the templates using cfcompile, and see what errors crop up from that.

From what I've been reading so far I think this regex should work:
[^#]#[a-fA-F0-9]{3,6}
If I'm correct it would pick up #FF3366 but not ##FF3366.
That will not just pick up #FF3366 it will *also* pick-up the character before
that (either space, colon, quote, etc).
If you are simply identifying matches, that doesn't make a huge difference -
however, it also means you need to manually fix matches, which is boring.
I explicitly used a negative lookbehind to exclude any preceeding hash without
also matching any characters, so that they can be escaped automatically with a
simple search/replace.
(You only need the a-f part if you are doing a case-sensitive match/replace -
given that this is as simple as ticking/unticking a checkbox in an IDE, I
didn't bother with that in any of my expressions.)
If you really want to use your CF application for this, you can easily access
java regex (which supports lookbehinds) by doing:
NewString = OldString.replaceAll('regex','replacement')
Which probably means you spend much less time manually escaping colours
everywhere.

Re: Regular Expression Help
Give this a go:
cfset Result = InputText.replaceAll
( '~\{(?:(?!/a).)+(?!\}~)(?=/a/li)'
, '$0}~'
) /
It uses the java replaceAll regex function so that it can do the negative
lookbehind to ensure existing correct items are not changed, meaning it can be
run multiple times.
Accepts any character (except newline) until it finds a closing A tag.
If newlines are required, that's just a one character change:
'~\{(?s:(?!/a).)+(?!\}~)(?=/a/li)'
(Which adds the 's' flag into what was a non-capturing group, meaning '.' also
matches newlines.)
If there's the possibly of a '~{' appearing outside this context, it may need
extra limits applied to work correctly.
Assuming there should not be any tags inside the ~{...}~ part, I would change
the '.' for a '[^]' which makes it a bit 'safer':
'~\{(?:(?!/a)[^])+(?!\}~)(?=/a/li)'

Re: What does this URL mean?
Here's a page which explains how URLs are made up: http://hybridchill.com/anatomy-of-a-url.html And here's how your URL divides: Protocol = http Server = //localhost Script Name = /students/index.cfm Path Info = /register Query String = action=studentreg It's possible (but unlikely) that students is a context not part of the script name. It's also possible (but even more unlikely) that index.cfm is a directory name and register is the script. If you're running the code yourself, you can open up index.cfm and do... cfdump var=#cgi# /cfabort/ ...and you'll see the various variables including those mentioned in the page above. Especially in the past, a lot of things used the Query String (which starts after the first ?) for things which *should* have used Path Info - mostly because Path Info was neither properly understood nor implemented in many servers, and server-side languages didn't make it as easy to work with as with query string. Path Info was designed for identifying which file to display (different to which script to process with), whilst Query String was intended for querying (searching) in some way. Because it was easier, nearly everyone lumped everything into the query string. There is no default format or imposed use to Path Info, so it is entirely a case of how the developer implemented it. It's possible it could be used for an application name, but I've never seen that done. It's likely to be the name of a page or section, which may or not be stored in a database. I've not encountered any CMS that constructs URLs in the way of your URL. Due to the intended purpose of the Query String, early search engines initially ignored everything after a ? when spidering URLs, but when Google arrived on the scene, it wasn't long before they had started working out which variables in a query string identified pages. At some point, a fad started of moving ALL variables (including ones which *should* stay in the query string) into the Path Info section, and claiming this was search engine friendly or search engine safe. (I'll try to avoid ranting on how stupid both these terms and practise is.) Mostly outside the CF community, people were already achieving the same thing using URL rewriting (using Apache mod_rewrite, IIS ISAPI rewrite, or similar), which treats everything after the Server before the Query String as a single virtual path, converted into a script name and (potentially) query string variables - which meant there was no need for index.ext to be used. This is generally called things like pretty URLs, vanity URLs, or similar terms - which more accurately reflect that they are (should be) done for HUMAN benefit (not search engines). That's starting to drify off the original topic though, so I'll stop now... I think I've covered everything, and hopefully this all makes sense? Let me know if anything I've written is unclear? ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:343639 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: REGEX hell
In this situation, there is no real difference between lazy or greedy - because the quantified item is mutually exclusive with the next characters - i.e. \s+ cannot match \) - so it will always consume to the end of the whitespace.

Re: Highlighting non-standard ASCII characters?
Hmmm, although it works that code is not quite correct - there's a few issues with it. If you don?t mind characters like ñ, then just use \w instead of A-Za-z0-9_ This is *incorrect* - in ColdFusion regex, \w does NOT include accented characters. There are other regex engines where it does, but the Apache ORO used by CF doesn't. (Unless that's changed with CF9 anyhow, but I suspect not..) There are several unnecessary escapes since .?() do not need escaping inside classes. (However, if '-' wants to be included (it's not currently) then it should be escaped as '\-' so it's not treated as a range.) By including \s you're not just saying space, you're *also* including \r and \n and \t and \v. So either just use a literal space (to avoid tabs) or to allow tabs don't specify the \r and \n since they're just adding noise. [^\w\r \n!.?''(),;:] or [^\w\s!.?''(),;:] Outside of the character class, the outer group is redundant - regex already captures the match to \0 so just do: rereplace( str , '[^\w\r \n!.?''(),;:]' , 'span class=highlight\0/span' , 'all' ) And finally, one more optimisation - to avoid a long series of HTML spans, just add a + to collect multiple characters together: rereplace( str , '[^\w\r \n!.?''(),;:]+' , 'span class=highlight\0/span' , 'all' ) Hope this helps. :) ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology-Michael-Dinowitz/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:337854 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

Re: CFParam vs. IsDefined
I prefer to CFParam my vars with a default value of a zero len string or a 0
for numeric values. Then I skip the isdefined and just test against the
value. Well recently someone I know said that it's better to test if it's
defined. Is there a pro or con to doing it my way vs. IsDefined ?
There is a difference between a value being undefined, and a value being zero.
Consider the following (contrived) example:
cffunction name=convertToKelvin returntype=Numeric output=false
cfargument name=Celsius type=Numeric default=0 /
cfargument name=Farenheit type=Numeric default=0 /
cfif Arguments.Celsius NEQ 0
...
cfelseif Arguments.Farenheight NEQ 0
...
cfelse
cfthrow message=Invalid arguments/
/cfif
/cffunction
vs
cffunction name=convertToKelvin returntype=Numeric output=false
cfargument name=Celsius type=Numeric required=false /
cfargument name=Farenheit type=Numeric required=false /
cfif isDefined('Arguments.Celsius')
...
cfelseif isDefined('Arguments.Farenheight')
...
cfelse
cfthrow message=Invalid arguments/
/cfif
/cffunction
(Using cfargument/default is equiv to using cfparam/default.)
Unless you can say with certainty that blank/zero is identically equivalent to
undefined, you should always check for existance (using either isDefined or
structKeyExists as preferred) instead of setting a default.

Re: sending a form through CF and catching the results
Josh, you're missing the point entirely. Converting from CSV-Query makes sense and wasn't being questioned. Using the cfhttp tag to do the conversion is what's crazy. There is no sensible reason for requiring CSV conversion to go via HTTP - since the vast majority of the time this isn't necessary/desired - having a dedicated cfcsv tag and/or CsvParse function would have made sense. As I said, we'd need to ask the relevant developers why the decision to tangle the CSV functionality with cfhttp was made.

Re: sending a form through CF and catching the results
Don't specify the columns attribute, it is not needed, and obviously doesn't work. (The columns attribute is part of cfhttp's csv parsing ability. Why cfhttp does CSV parsing instead of having dedicated CSV functions is something only Adobe can tell us.) Use the cfhttpparam tags to send through formfields. If you don't know what form fields there are, load the first page with cfhttp (where the form is), run the results through a HTML parser (you can use XmlParse if it's valid XHTML) and extract a list of fields to send with the second cfhttp request. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology-Michael-Dinowitz/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:336514 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

Re: sending a form through CF and catching the results
Oh and name is incorrect attribute too. Should be result to change the default 'cfhttp' variable name. There's a lot of hidden fields you probably need to pass in - here's some code that will get you a step closer. (Note how the cfhttp tag only has URL and METHOD attributes - nothing else is needed for standard behaviour like this.) cfhttp method=POST url=https://jobs.umd.edu/applicants/Central; cfhttpparam type=FORMFIELD name=searchDelegate value=searchDelegate / cfhttpparam type=FORMFIELD name=actionParameter value= / cfhttpparam type=FORMFIELD name=windowTimestamp value=PA_1282756650239 / cfhttpparam type=FORMFIELD name=collegeDivision value=20 / !--- 20 is value for SPHL - School of Public Health --- cfhttpparam type=FORMFIELD name=searchType value=8192 / cfhttpparam type=FORMFIELD name=formAction value=goSearch / cfhttpparam type=FORMFIELD name=button_goSearch value=Search / /cfhttp cfdump var=#cfhttp# / The URL I'm using there is taken from the form's action attribute. It returns a 302 instead of search results - probably because there's still some missing fields or it doesn't like the windowTimestamp or whatever. But all of this seems to be a waste of effort - is there a reason you can't just ask the guys who created this to do one specifically for your department? ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology-Michael-Dinowitz/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:336524 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: Number of site using ColdFusion
To respond to an IT director who thinks ColdFusion is dated and not in much use anymore... Well if he's determined, he'll just return with how many sites run on PHP or .NET or whatever. Numbers don't help for CF - what you need to demonstrate is how active and passionate the community is. A recent post by Terry Ryan might help there: http://www.terrenceryan.com/blog/post.cfm/dear-coldfusion-denier One specific point Terry makes: check out the list of ColdFusion conferences. A third of them are new conferences and have popped up over the past 3 years. He's got another posting linked from that one, which has this Cost of Ownership image: http://www.terrenceryan.com/blog/assets/content/toc.png Basically showing that CF requires less training, less dev time and less maintenance.

Re: Make HomeSite+ Open Source? (WAS: RE: Development Apps - Does anyone use homesite still?)
There's little point in making it Open Source. It might be a nice gesture from Adobe, but it's hard enough finding CF developers willing to do Java; finding a Delphi developer willing to support HomeSite would be even worse! For the people that like Homesite, there's nothing wrong with continuing to use it, once you don't mind a lack of updates. (This is assuming the updates are some form of proprietary/binary format; if they are text-based then the CF9 stuff yourself!) I tried CFECLIPSE and I tried the beta version of Adobes CF developer thing. Both are nice, both are a drain on system resources, slow, and bloated. Yep, CFEclipse and CFBuilder *are* slow and bloated - because they use the Eclipse platform, which is slow and bloated. It *might* be possible to produce a minimalised/streamlined Eclipse base with just the required stuff in - but there are so many other things that CFEclipse needs first, and only a limited number of people able to spare a limited amount of time to work on improving it. The great thing is that if people want CFEclipse to be better, they can help to make it better! You do NOT need to know Java to help with CFEclipse - there's plenty of other tasks that can be done, and doing those will mean that the Java developers can concentrate on the Java tasks, and thus everything improves. So, if there's things you don't like about CFEclipse (either bugs or feature requests), raise them on the issue tracker - problems can't be fixed if they're not known! And, if you want to speed their resolution, pop on to the mailing list ( cfeclipse-us...@googlegroups.com ) and see if you can help out - either directly working on them, or indirectly (by improving other areas), and hopefully it wont be long before we've all got a great IDE! ~| Want to reach the ColdFusion community with something they want?

Re: REReplaceNoCase and dynamic query columns
Is it possible to dynamically evaluate the temp variable from the regular expression and use it as a ColdFusion variable? It's not a temp variable from the regular expression, it is a variable which exists *within the scope* of that regular expression. That's important to understand - given this expression: REReplaceNoCase(REQUEST.theURL, '%%(\w+)%%', #REQUEST.myQ[/\1][1]#, 'ALL') The CF expression is evaluated *before* the regex does its stuff, and thus the \1 never enters the regex 'scope', and doesn't gets treated as a regex back-reference. (hope that explanation makes sense?) Depending on if/how you want to handle invalid columns, one solution which wont cause errors is to simply loop through the query column names, like so: cfset Request.Final = REQUEST.theURL / cfloop index=CurCol list=#REQUEST.myQ.ColumnList# cfset Request.Final = replace(Request.Final,'%%#CurCol#%%',REQUEST.myQ[CurCol][1],'all') / /cfloop That will mean that any mis-named columns are still in the string - so you may want/need to look for remaining %% in the string and behave appropriately. But, going back to the regex solution for this - which can be more flexible, and is definitely worth knowing - the way to do this is to use a regex replace function which allows you to pass a function as the third argument. Afaik none of the three main CFML engines allow this (yet), but I do have a CFC that enables assorted regex features, including passing a function: http://hybridchill.com/projects/jre-utils.html Once you've created the object (named jre below), you can then do: cfset REQUEST.final = jre.replace( REQUEST.theURL , '%%(\w+)%%' , MyFunction , 'all' ) / Then, you can create a function (see the callback function example at the above link) named MyFunction and return this: cfreturn REQUEST.myQ[ Arguments.Groups[1] ][1] / And that should all ultimately work as you were going for initially. Hopefully all this makes sense - let me know if any questions/etc. :) ~| Want to reach the ColdFusion community with something they want?

Re: Regex help with invalid HTML
I have no control over this code The only time parsing HTML with RegEx might be remotely viable is when you know what that code will be - if the HTML is uncontrolled then using RegEx is a futile effort. RegEx is for dealing with Regular text, and HTML is not a Regular language - even modern regex engines that implement non-Regular features *cannot* deal with the potential complexity of HTML. The correct solution is to **use a tool designed for parsing HTML**. There isn't one native to CF, but there are a number of Java ones available - take a look at: http://java-source.net/open-source/html-parsers I haven't used any of those, I'd probably start with TagSoup or NekoHTML since they look promising, but any HTML parser that produces a DOM structure which you can run XPath expressions against will allow you to extract the specific information you want. So yeah, it might involve a bit of effort getting one of those to work, but it's far more stable and reliable than attempting to use regex for something it simply isn't designed for. ~| Want to reach the ColdFusion community with something they want?

Re: REReplace Statment Help
This will replace everything that is not alphanumeric with a dash: ProductPageName = rereplace( Form.PageName , '\W' , '-' , 'All' ) However, the above will change this that to this---that, if you would prefer a single dash in situations like this, you can simply do this: ProductPageName = rereplace( Form.PageName , '\W+' , '-' , 'All' ) \W in that regex stands for non-word-character, equivalent in CF to [^a-zA-Z0-9_] ~| Want to reach the ColdFusion community with something they want?

Re: Checking line 26 or 27
This doesn't sound like a very robust method. Are you able to provide sample invoice(s)? ~| Want to reach the ColdFusion community with something they want?

Re: Checking line 26 or 27
As I said, relying on line numbers doesn't seem like a robust method - what happens if the top of the invoice is changed, and it suddenly becomes line 15/16 or 32/33 or something else? Ideally you refer specifically to the location of the invoice number, hence asking for a sample of the invoice to see what structure it uses. If you r*eally* want to deal with line numbers, then you can split the content into an array and do something like this: cfif Len(line[26]) cfset InvoiceNo = line[26] / cfelseif Len(line[27]) cfset InvoiceNo = line[27] / cfelse cfthrow message=Can't locate invoice number. / /cfif (Or, if this is the only time you're looking at lines, use ListGetAt with newlines as delimiters) ~| Want to reach the ColdFusion community with something they want?

Re: Checking line 26 or 27
The Invoice will not change, its only ever going to be on line 26 or line 27 I'd say the odds of that being the case are low... things like this frequently come back to bite you. I tried your code but all i get is an error messag saying: You have attempted to dereference a scalar variable of type class java. lang.String as a structure with members. Something like this *might* work: cfset Lines = ListToArray( Lines , Chr(10)Chr(13) ) / But don't just copy and paste that - make sure you know what it's actually doing, and that you know the difference between strings, arrays, structs, and so on. ~| Want to reach the ColdFusion community with something they want?

Re: Checking line 26 or 27
Just noticed you're using rematch there - which is good since ListToArray will remove blank lines (not what we want). However, you can simplify it - instead of the crlf variable you can do: cfset lineArray = reMatch( '\r\n' , myFile ) / And, once you're there, it's one extra character to do: cfset lineArray = reMatch( '\r?\n' , myFile ) / Which will work with files that don't have carriage returns. ~| Want to reach the ColdFusion community with something they want?

Re: special/reserved characters
A very quick summary... Use cfqueryparam tags to insert user-provided data into the database. Use the appropriate function (HtmlEditFormat, XmlFormat, UrlEncodedFormat, JsStringFormat) to output user-provided data. These will (should) deal with escaping all reserved characters. If in doubt, use security scanning software to run some thorough tests against your site and verify it is ok before you put it Live. ~| Want to reach the ColdFusion community with something they want?

Re: CFPDF Thumbnail quality
I'm converting PDFs to image format, and would expect some kind of control over the output quality - I'm writing a JPG after all. Yep, and you *should* have the option to set a compression percentage for that, so I would raise that bit as a bug. I'm guessing the resolution setting is probably a developer copying through possible arguments from whatever underlying API they are using for this. ~| Want to reach the ColdFusion community with something they want?

Re: CFPDF Thumbnail quality
The resolution of an image defines the default physical size it gets sent to the printer as (and it can generally be overridden at print stage anyway). So you can probably ignore it. ~| Want to reach the ColdFusion community with something they want?

Re: CFPDF Thumbnail quality
resulting images are identical in size. I checked the actual resolution in Fireworks and it's 72 for both images. It may well be that Fireworks is ignoring the value provided - you'll need to use a metadata viewer to find out what value the actual file has, rather than a graphics editor. Even then, if it's always set to the same value then it is a bug - but an incredibly trivial one since it can be easily changed at print time anyway. ~| Want to reach the ColdFusion community with something they want?

Re: Listserves vs. Message Boards
The client doesn't know...they want the pros/cons. From what you've said, I'm inferring that they will mostly have 'normal' people using their systems. The main pro of mailing lists is that they're convenient for busy techies. Some cons of mailing lists is that they're limited and inflexible, you're at the mercy of email servers, and on a high-volume list you need to setup filters to avoid your inbox being inundated. Web-based interfaces to mailing lists can help a little, but in general, they're just a bandage. Which isn't to say forums are perfect - even the best ones have big flaws - but (for an audience of non-techies) I would certainly default to a choice forum over list. So, the question then becomes *which* forum to go with, which raises a few questions: * Define in-site - does it have to integrate with a site layout, or is it enough to be styled similarly? * What languages run on the server? (Just CF, or is PHP possible? PHP has far more choice). ~| Want to reach the ColdFusion community with something they want?

Re: Listserves vs. Message Boards
I don't see why anyone would have a problem using listserves... And that's part of the reason why there's such a significant divide. Technical people are fine with mailing lists; they understand them and can generally setup their email client in a suitable way, and they don't get what's wrong with it. Non-technical people are fine with forums, and don't see why people use mailing lists. What you refer to as 'hybrid' are generally mailing lists with web interfaces tacked on, and those web interfaces simply don't compare to what a full forum system gives you. The downside is that forums are all made by people that don't see the benefits that mailing lists have, so you don't get proper email-based interfaces (best case is notification emails with replies inline without having to click a link). There is no reason that they cannot both be properly united, (other than a lack of understanding on what attracts people to one or the other). This is something that has bugged me for *years* - one of my first projects after learning CF was to try building a great multi-interfacing discussion package, but I didn't know enough back then and it went nowhere. At the moment, I'm cautiously optimistic that Wave might help with solving the problem, but since Google have stopped doing password resets, I've been unable to login and start experimenting with that. :( But anyway, until we have that unified discussion system, the original question comes down to what the majority of the users are. My suspicion of Randy's Client's intended audience is that - if he picked a mailing list - they'd 99.9% be using the web interface, so he's better off with a proper forum package. If that turns out to be not the case, then a mailing list might indeed be a better choice. ~| Want to reach the ColdFusion community with something they want?
