CFML Functions

You can already execute CFML functions in the REPL command to play in a sandbox, but sometimes you want to go further and actually use CFML directly in the CLI. This is where the cfml command comes in handy. The following runs the now() function. It is the equivalent to repl now().

cfml now


As a handy shortcut, you can invoke the cfml command by simply typing the name of the CFML function, preceded by a # sign.


Function parameters

When you pass parameters into this command, they will be passed directly along to the CFML function. The following commands are the equivalent of hash( 'mypass' ) and reverse( 'abc' ).

#hash mypass
#reverse abc

Piping them together

This really gets useful when you start piping input into CFML functions. Like other CFML commands, piped input will get passed as the first parameter to the function. This allows you to chain CFML functions from the command line like so. (Outputs "OOF")

#listGetAt 2 . | #ucase | #reverse

By piping commands together, you can use CFML functions to transform output and input on the fly to generate very powerful one-liners that draw on the many CFML functions already out there that operate on simple values.

Complex Values

Since this command defers to the REPL for execution, complex return values such as arrays or structs will be serialized as JSON on output. As a convenience, if the first input to an array or struct function looks like JSON, it will be passed directly as a literal instead of a string.

The first example averages an array. The second outputs an array of dependency names in your app by manipulating the JSON object that comes back from the package list command.

#arrayAvg [1,2,3]
package list --JSON | #structFind dependencies | #structKeyArray

The sky is the limit with the mashups you can create. This example runs your native java binary, uses CFML functions to strip out the first line, and then grabs a portion of that string via regex in the sed command.

echo "java -version" | run  | #listToArray `#chr 10` | #arrayFirst | sed 's/java version "(.*)"/\1/'

Named Parameters

You must use positional parameters if you are piping data to a CFML function, but you do have the option to use named parameters otherwise. Those names will be passed along directly to the CFML function, so use the CF docs to make sure you're using the correct parameter name.

#directoryList path=D:\\ listInfo=name
