**Library**

This is an example of a library. You may see a list of other libraries used on Rosetta Code at Category:Solutions by Library.

**Wren-fmt** is a module which adds basic formatting capabilities to the Wren programming language. It consists of static methods organized into 2 classes: Conv and Fmt. As it is expected they will be mostly used within interpolated strings, most methods in the Fmt class have very short names reminiscent of the *printf* verb names in C-family languages.

It is the first in a series of modules (listed on the language's [main page]) designed to assist with writing Rosetta Code tasks so the same code does not have to be written or copy/pasted time and time again thereby bloating a task's script code unnecessarily.

To use it all you need to do is to copy the source code (in the [talk page]) to a text file called *fmt.wren* and place this in the same directory as the importing script so the command line interpreter can find it.
