CFLib
CommandBox can install UDFs from the popular site CFLib.org. Each project on CFLib is a single CFML function. You can find UDFs via the web site and copy the URL slug for a given UDF to use in your installation.
For example, if the URL to a given UDF is http://www.cflib.org/udf/CalculateWindChill, the slug you'll want to use would be CalculateWindChill.
Standard Installation
To install a package from CFLib, use the slug from the website's URL like so:
This will create a folder in your installation directory named after the UDF containing a .cfm file of the same name. The above command would create the following folder:
That file contains a single function that you can call. It is up to you to include that file where ever you want to use the UDF.
ColdBox Installation
If you're using ColBox, you can use a slightly different version of the CFLib endpoint called CFLib-ColdBox which will wrap up the UDF inside a CFC and place it in an ad-hoc module which automatically registers the model with WireBox.
This frees you up from needing to manually include the file. Once you install the module, you can immediately ask WireBox for the UDF using the convention UDFName@cflib. WireBox will register this mapping by convention so there is no additional setup required to use the UDF.
Or inject the wrapped UDF to use in your handlers or models.
Package Metadata
Packages installed from the CFLib endpoint don't have any way to get new version information. They will always show as outdated using the outdated or update commands and their downloads will not get stored in the artifact cache.
You can specify packages from the CFLib endpoint as dependencies in your box.json in this format.
