Currently I'm putting newlines in strings through one of these two methods:

<cfset someStr="This is line 1" & Chr(10) & "This is line 2" & Chr(10) & "This is line 3" />

OR

<cfset NL=Chr(10) />
<cfset someStr="This is line 1#NL#This is line 2#NL#This is line 3" />

Is there anything more like the Java/C++ way? Something more like this I mean:

<cfset someStr="This is line 1\nThis is line 2\nThis is line 3" />

Not directly in CF, I'll leave it to the CF-Java dudes to say whether you can use a Java method directly on a CF var to achieve what you want, but...

You could use cfsavecontent to put natural line breaks in:

<cfsavecontent variable="someStr">
This is line 1
This is line 2
This is line 3
</cfsavecontent>

Then check it with:

<cfoutput>
<pre>#Trim(someStr)#</pre>
</cfoutput>

Note that the Trim() is there to get rid of the first and last line breaks if you don't want them.

Your way is correct. There is no support for \n or \r in CF. From the Live Docs

  • Chr(10) returns a linefeed character
  • Chr(13) returns a carriage return character
  • The two-character string Chr(13) & Chr(10) returns a Windows newline

i use this:

<cfset br = "#chr(13)##chr(10)#">
<cfset someStr="This is line 1#br#This is line 2#br#This is line 3" />

If you are into platform-independent development, you can do:

<cfset NL = CreateObject("java", "java.lang.System").getProperty("line.separator")>

For example, in your application.cfm/cfc or somewhere else high-level and use that.

that's pretty cool. i'm new to CF, so i haven't really tapped the potential of the underlying java code yet...

I was wondering if something like this would work:

<cfset str = CreateObject("java", "java.lang.String").init("Line 1\nLine 2\nLine 3")>

<cfoutput>
<pre>#str#</pre>
</cfoutput>

Alas no :O(

This feeds a CF string to .init(). And a CF string does not understand "\n". That's a kind of problem I like to refer to as "can-opener in a can". :-)
Tomalak
good try though! :)
