p6doc -- an attempt to write something like 'perldoc' for Perl 6

Build Status artistic

An HTML version of this documentation can be found at

(If you are browsing this repository via github, it will not display most files correctly, because this is Perl 6 Pod, and github assumes Perl 5 POD).


This module is available via the Perl 6 module ecosystem. Use

zef install p6doc

to install the binaries and make it available in your binaries execution path.

Once it has been downloaded, run

p6doc-index build

to build the index.


With a Rakudo perl6 executable in PATH, try

./bin/p6doc Type::Str

to see the documentation for class Str, or

./bin/p6doc Type::Str.split

to see the documentation for method split in class Str. You can skip the ./bin part if you have installed it via panda or zef. You can also do

p6doc -f slurp

to browse the documentation of standard functions. Depending on your disk speed and Rakudo version, it might take a while.

Building the HTML documentation

Install dependencies by running the following in the checkout directory:

panda installdeps .       # if you use panda
zef --depsonly install .  # if you use zef

If you use rakudobrew, also run the following, to update the shims for installed executables:

rakudobrew rehash

In addition to the Perl 6 dependencies, you need to have graphviz installed, which on Debian you can do by running

sudo apt-get install graphviz

To build the documentation web pages, simply run

$ make html

After the pages have been generated, you can view them on your local computer by starting the included program:

$ make run

You can then view the examples documentation by pointing your web browser at http://localhost:3000.

You will need at least Mojolicious installed and you will need nodejs to perform highlighting.

Help Wanted!

Perl 6 is not a small language, and documenting it takes a lot of effort. Any help is appreciated.

Here are some ways to help us:

  • add missing documentation for classes, roles, methods or operators
  • add usage examples to existing documentation
  • proofread and correct the documentation
  • tell us about missing documentation by opening issues on github.
  • Do a git grep TODO in this repository, and replace the TODO items by actual documentation.

Issues page has a list of current issues and documentation parts that are known to be missing and CONTRIBUTING explains briefly how to get started contributing documentation.

Some notes:

Q: Why aren't you embedding the docs in the CORE sources?
A: Several reasons:

  1. This documentation is intended to be universal with respect to a given version of the specification, and not necessarily tied to any specific Perl 6 implementation.
  2. Implementations' handling of embedded POD is still a bit uneven; this avoids potential runtime impacts.
  3. A separate repo in the perl6 Github account invites more potential contributors and editors.

Q: Should I include methods from superclasses or roles
A: No. The HTML version already includes methods from superclasses and roles, and the p6doc script will be taught about those as well.

Q: Which license is this stuff under?
A: Both code and documentation are available under the Artistic License 2.0 as published by The Perl Foundation. See the LICENSE file for the full text.


I want p6doc and to become the No. 1 resource to consult when you want to know something about a Perl 6 feature, be it from the language, or built-in types and routines. I want it to be useful to every Perl 6 programmer.

Wishlist stuff:

  • Perl 6 implementations could embed P<...> tags in their source code that would then inline the corresponding entry from p6doc. This would enable things like &say.WHY to (dynamically!) retrieve the documentation string from p6doc, without having to duplicate the documentation in the CORE.setting sources or to encode the documentation into the binaries.


    # In Rakudo's src/core/
    #= P<p6doc/&print>
    sub print(|$) { ... }
    #= P<p6doc/&say>
    sub say(|$) { ... }
    #= P<p6doc/&note>
    sub note(|$) { ... }
