Kinda expected this to work?

myList = “1,2,3,4,5” ;

for(item in myList){
writeOutput(item);

Not sure why?

Because it is practical and avoids converting the string to an array.

Thanks,

p.s. Adam, I’ve just checked and this works:

mystring = "this is a string" mystring.each( function( char ){ echo( char ); } ); On 2 June 2015 at 17:22, Dominic Watson <@Dominic_Watson> wrote:

A native string.split( regex ) would be great too; avoiding the ‘list’
baggage and implementing more flexible splitting using regex rather than a
list of single character delimiters.

I personally agree with you, but the driving force behind fixing this
issue was ACF compatibility.

if anything, I would prefer

for (ch in someString) { /* ... to iterate over the characters of

but then compatibility would completely break…

I’ve been mulling over a sensible syntactical tweak to disambiguate
between “by list element” and “by char”, but drew a blank.

However it’s perhaps better to join the current decade and take an OO &
FP approach to these things, by implementing String.each(), .reduce(),
.map(), .sort(), .filter(), etc

It makes for more clear code to use purpose-specific iteration methods,
rather than generic and procedural looping statements.

It was good though, I decided to look up the initial change to lucee, which
encouraged me to take a closer look at the underlying code.

So all in all a good result.On Tue, Jun 2, 2015 at 7:51 PM, AJ Mercer <@AJ_Mercer> wrote:

Good point, the solution for this has not been implemented properly, as
the delimiter has been hard-coded (as a comma):

return ListUtil.listToArray(o.toString(), ‘,’).getIterator();

(that’s from the commit linked-to in

It shouldn’t be hard-coded at all, for a start; but it should be

I am with you on the looping over chars bit.

I now realise the context (I didn’t when I replied this morning) to this whole discussion.

I didn’t realise there was some compat ticket lurking about "for loops”.

Not sure how I could have from the original post without reading between the lines.
All I read was
"Kinda expected this to work?”

And I replied that I wouldn’t.

I guess I stand corrected.

I have seen too much crap code using lists (Gert will back me up on this. Inside joke etc) that they make my skin crawl. Hence my questioning. Arrays are faster but I guess if under the covers it converts it to an array for you to loop through then fair enough. Go listy listy!

I would not add “for in” string list support in .lucee dialect (my opinion).

I agree with some people that looping over a string is not efficient over
Arrays. I would use the available cf string utilities (just like java did
with their string tokenizer for e.g)

If it is intended be a shorcut for converting string list to an array then
it must add a “delimiter” parameter.
I’m not a Lucee code contributor but for example the current 4.5.1.016 (and
master branch) implementation only works with comma separated string list.On Tuesday, June 2, 2015 at 9:37:36 AM UTC+2, Adam Cameron wrote:

Indeed. Whilst CFML makes a claim that there is such a thing as a list
(which is string with element delimiters in it: we get that), then it
stands to reason that all the usual collection-iteration possibilities are
availed to it.

In for a penny, in for a pound. Even if they penny is misshapen and not
accepted as legal tender anywhere else.

That said: hands up who’d like to list support in .lucee entirely? [raises
hand. Raises other hand too].

Thanks for the ticket feedback :slight_smile:

Even if for-in with list is supported by ACF, their docs are not up-to-date

didn’t search enough).
I hope others won’t do the same forgetting as we need to know how to pass

A clearer way to do all of this IMO is:
for (item in list.split(“”)) { // loop over chars
}

for (item in list.split(“,”)) { // loop over list elements
}
Sure, it uses reflection, but we’re talking about lists. They are already
not great performance-wise.

for (element in list[; delimiter[; multi-char]]);

I would be against that for the same reason that you cannot specify the
“step” (eg, every other element) in a for…in array loop. Plus, this is
all because of ACF compatibility. I say this type of list loop is bad
design to begin with, but since Lucee strives for ACF compat, it should be
supported for the CFML dialect - but only to the level Adobe has supported
it. I surely hope the for…in list construct does not apply to the .Lucee
dialect…

Not quite. This:

MaList.listEach(function(x){

});

Which I think we have already.

and

MaString.each(function(){

No. Dogmatically going “it’s just a string”, and being in denial that CFML has a concept that is a string-based collection is what’s stupid.

It was just not very performant. I have seen code that had 100’s of ListGetAt all over the place in one template hence my negative attitude to use lists as a collection.

As I said before, I wouldn’t use it and if Lucee converts it to a nice array under the covers for you, then great. Go for it.

Turns out I was hasty with my .each() example. It works, but not as I had
expected. This is what you get:

mystring = "this is a string"; mystring.each( function( char ){ echo( char & char ); } );

Outputs: “this is a stringthis is a string”.

You can specify a delimiter after the closure however:

mystring = "this is a string"; mystring.each( function( char ){ echo( char & char ); }, "" );

Outputs: tthhiiss iiss aa ssttrriinngg

Perhaps there is a way to set delim there, but not sureOn 2 June 2015 at 17:24, Mark Drew <@Mark_Drew> wrote:

you mean something like:

var MaList = new List(“Tahi,Rua,Toru,Wha”);

for(s in MaList.each()){

}

and

var MaString = “Elvis is the bomb!”;

for(c in MaString.each()){

}

That is much clearer in a way
?

@Mark –

I personally agree with you, but the driving force behind fixing this
issue was ACF compatibility.

if anything, I would prefer

for (ch in someString) { /* ... to iterate over the characters of the

string … */ }

but then compatibility would completely break…

I’ve been mulling over a sensible syntactical tweak to disambiguate
between “by list element” and “by char”, but drew a blank.

However it’s perhaps better to join the current decade and take an OO & FP
approach to these things, by implementing String.each(), .reduce(), .map(),
.sort(), .filter(), etc

It makes for more clear code to use purpose-specific iteration methods,
rather than generic and procedural looping statements.
