It is the thirty-third in a series of modules (listed on the language's [https[://rosettacode.org/wiki/Category:Wren |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 you need to copy the Wren source code (in the [https[://rosettacode.org/wiki/Category_talk:Wren-i64 |talk page]]) to a text file called ''i64.wren'' and place this in the same directory as the importing script so the Wren-i64 executable can find it.

As there is a dependency on the ''Wren-trait'' module, you also need to copy that (if it is not already present) to the same directory as described [https[://rosettacode.org/wiki/Category:Wren-trait |here]]. Unless you are using classes in that module directly, there is no need to 'import' them into your script and the ''Comparable'' class can even be imported via Wren-i64 itself.

Currently, Wren-cli does not support plug-ins though this or similar functionality is likely to be added in a future version (it's already present in [https[://rosettacode.org/wiki/Category:DOME |DOME]]). Consequently, scripts using the Wren-i64 module must be run under the control of a special executable whose source code (wren-i64.c) is also included (in the [https[://rosettacode.org/wiki/Category_talk:Wren-i64 |talk page]]). This executable translates Wren method calls to calls to the corresponding C99 functions and can be built with a command line such as the following using GCC under Linux:
