Module Listing
Date of Compilation
Updates and Algorithm


The developers of Perl6 decided that the implementation of the language (eg. Rakudo) would be available with a bare minimum of "core" modules. Some modules are essential, such as Test, or the module manager (previously panda, currently zef).

The intention is for users / user groups to contribute distributions that meet a specific topic area. Rakudo itself is available in a package called Rakudo Star with a minimal number of modules.

This distribution list takes another, data driven, approach.

Modules are intended to provide common functionality, and so are used or cited by other modules in the Ecosystem. A set of modules that are frequently used can be fairly safely assumed will be regularly maintained. Failures in these modules will affect many other modules, and there will be pressure to get them fixed.

This list uses Citation Indices to identify the 30 modules most recursively popular modules in the Ecosystem.

Date of Compilation

This list was compiled on 2018-01-01.


Inevitably for commonly needed functionality, there may be multiple modules that provide the same functionality. An example is JSON::Tiny and JSON::Fast. J/Fast was designed to be a drop-in replacement for J/Tiny, which was first written to demonstrate how to use Perl6 and not as a workhorse module. However, for some reason J/Tiny has a lot of support, although J/Fast is taking over (see the ModuleCitation page to trace the historical change).

So the Task::Popular list may have alternate modules for the same functionality. But for a newcomer to the Ecosystem that might in fact be interesting as it provides a choice, and the opportunity to compare coding styles.

Updates and Algorithm

The aim is to update the list regularly (eg. monthly).

The algorithm for generating the distribution list is implemented as a method in the ModuleCitation class.
