ColdFusion (2018 release) introduces Read-Eval-Print-Loop (REPL). REPL, a shell, is an interactive programming environment that takes single user inputs, evaluates them, and returns the result to the user.
For more information, see REPL.
Try out your ColdFusion REST services in the new REST Playground. Use the REST Playground to test, develop, and document web services.
For more information, see REST enhancements in ColdFusion (2018 release).
Boost performance through caching with the newly added engines:
- Memcached
- JCS
- Redis
- Custom cache plugin
For more information, see Caching enhancements.

- Import code profiler data
- Introduction of Cordova
- Eclispse upgrade to Oxygen
For more information, see What's new in ColdFusion Builder.
In this release, we have added support for making semicolons optional in cfscript. For example, the snippet below does not use any semicolon at the end of a statement.
<cfscript>
animals = ['cat','dog','fish','bison']
lastAnimal=animals.last()
writeOutput("The last element of the array is: " & lastAnimal)
</cfscript>
<cfscript>
for(i=1;i<9;i++){
for(j=1;j<=i;j++)
writeoutput("*")
writeoutput("<br/>")
}
</cfscript>
<cfscript> cfhttp(url="http://localhost:8500", timeout="60") </cfscript>
component{
function myfunc(){
writeoutput("Optional Semi Colon Example")
}
}
In closures in tags,
A semi-colon is also optional while defining the body of closure functions in tags. For example,
<cfset closureFunc1=function(){
return true
}>
In the 2018 release of ColdFusion, there is support for negative index for a string’s left and right functions.
<cfscript> myString='Welcome to ColdFusion' writeoutput( myString.right( -1 ) & "<br>") writeoutput( myString.left( -1 ) & "<br>") writeoutput( myString.right( -8 ) & "<br>") writeoutput( myString.left( -8 ) & "<br>") </cfscript>
<cfscript>
// Example 1
myarray=ArrayNew(1);
new_arr= myarray.clear().Resize(10).set(1,10,"blah");
writedump(new_arr);
</cfscript>
<cfscript>
// Example 2
ordered_struct=["key1":"val1","key2":"val2"]
unordered_struct={"key3":"val3","key4":"val4"}
new_struct=unordered_struct.append(ordered_struct).update("key4","updated val4").insert("key5","inserted val5");
writedump(new_struct);
writedump(unordered_struct);
</cfscript>
Apart from adding these functions, the following member functions return appropriate array or struct values, as required when chaining the functions.
- Array
- arrayObj.clear()
- arrayObj.deleteAt()
- arrayObj.delete()
- arrayObj.deleteNoCase()
- arrayObj.insertAt()
- arrayObj.prepend()
- arrayObj.resize()
- arrayObj.set()
- arrayObj.sort()
- arrayObj.swap()
- Struct
- structObj.delete()
- structObj.insert()
- structObj.update()
- Async Member Functions
- then(UDFMethod method)
- then(UDFMethod method, long timeout)
- error(UDFMethod method)
- error(UDFMethod method, long timeout)
- get()
- get(long timeout)
- cancel()
- isCancelled()
- isDone()
In this release, there is support for new operator/syntax for com, component, CORBA, Java,. Net, webservice. For examples,
- obj1 = new java("java.lang.String")
- m = new component("employee ")
For examples,
Employee.cfc
component {
public numeric function getPaid() {
var salary=40*20;
return salary;
}
}
component extends="employee"{
public numeric function getPaid(){
var salary=1.5*Super.getPaid();
return salary;
}
}
component extends="manager"{
public numeric function getpaid(){
var salary=1.5*Super.getPaid();
return salary;
}
}
<cfscript>
// change the paths as required
empObj=new component("path/to/employee.cfc");
manObj=new component("path/to/manager.cfc");
presObj=new component("path/to/president.cfc");
writeOutput("Employee earns: " & empObj.getPaid() & "<br/>");
writeOutput("Manager earns: " & manObj.getPaid() & "<br/>");
writeOutput("President earns: " & presObj.getPaid() & "<br/>");
</cfscript>
Named parameters enable you to specify an argument for a parameter by associating the argument with the parameter's name rather than with the parameter's position in the parameter list. You can use named parameters in functions and constructors.
In earlier versions of ColdFusion, named parameters were allowed in user-defined functions and in component constructors.
In ColdFusion (2018 release), you can use named parameters for built in functions.
In previous versions of ColdFusion, the order of parameters in a BIF was necessarily fixed, since it was the only way that ColdFusion could identify which value is intended to be used for which purpose. Now with named parameters, the position or order of parameters does not matter; the arguments are evaluated in the order in which they appear in the list.
For parameter names, refer this document.
<cfscript>
myarray= [4,2,1,3]
writeoutput(ArrayFind(array=myarray, value="4"))
writeoutput(Arrayfind(callback=function(index,item){
if(index == item)
return true
else
return false
}, array=myarray))
</cfscript>
ArrayFind can either accept a value to find in an array or a callback that has the searching logic. You can use both value or callback with named parameters as shown in the snippet above.
<cfscript>
writeOutput("ABCDEFGHIJ".substring(1,7).substring(2,5).lCase().len());
</cfscript>
ColdFusion (2018 release) uses Hibernate 5.2. The following are the highlights:
- Hibernate 5 XML Parser now uses JAXP (Java API for XML Processing). As a result, the way of declaring the class name in hbmxml ORM mapping file has changed, for example, cfc:cfsuite.orm.settings.dialect.invalid_dialect.invalid_dialect to cfc.cfsuite.orm.settings.dialect.invalid_dialect.invalid_dialect.
- Hibernate 5 no longer supports seqhilo generator.
- Hibernate 5 no longer supports offset queryoptions as it was inefficient and most of the underlying databases have the support for offset. However, this functionality can be enabled by setting the flag hibernate.legacy_limit_handler to true in the hibernate configuration file.
- Hibernate 5 Schema Update/Export validates the case sensitivity in table names. If the table name defined in CFC and database are in different cases, it does not work. The previous version of Hibernate allowed tables names defined in CFC and database to be case-insensitive.
- You must update an entity inside a transaction.
In the wsconfig tool, there is a new option related to tuning of connectors.
- Heartbeat Interval in seconds: The time interval in seconds after which the connector load data is sent to ColdFusion.
