About the Docs
This document collection represents the on-going effort to document the Perl 6 programming language with the goals of being: comprehensive; easy to use; easy to navigate; and useful to both newcomers and experienced Perl 6 programmers.
An HTML version of the documentation is located online at https://docs.perl6.org.
The official source for this documentation is located at perl6/doc on GitHub.
This particular document is a quick overview of the process described in more detail in CONTRIBUTING on GitHub. This document also provides a short introduction to writing Perl 6 Pod files, which can be rendered into HTML and other formats.
All of the documentation is written in Perl 6 Pod and kept in the
doc/ directory, and the
doc/Type/ sub-directories. These files are processed as collections of definitions or "documentables", which are then post-processed and linked together.
To generate HTML from the Pod files, you'll need:
A recent version of the Rakudo Perl 6 compiler
The Perl 6 modules Pod::To::HTML, Pod::To::BigPage, and URI::Escape (can be installed via zef).
Optional: GraphViz, for creating graphs of the relationships between Perl 6 types
To generate the documentation into the
html/ folder, run:
To host the documentation from a web server, have Perl 5 and Mojolicious::Lite installed, then run:
perl app.pl daemon
The documentation is written in Perl 6 Pod.
For a quick introduction to Perl 6 Pod, see Perl 6 Pod.
For full details about the Perl 6 Pod specification, see Synopsis 26, Documentation.
Documentables can be defined using an
=headN Pod directive, where
N is greater than zero (e.g.,
All of the paragraphs and blocks following that directive, up until the next directive of the same level, will be considered part of the documentable. So, in:
=head2 My Definition Some paragraphs, followed by some code: my Code $examples = "amazing"; Mind === blown. =head3 Minor details about My Definition It's fantastic. =head2 And now, for something completely different …
The documentable My Definition extends down to the
=head2 And now….
Documentables may contain other documentables. Class documentables, for example, often contain the methods the class implements.
Definitions must be in one of the following forms to be recognized as the start of a documentable named, say, þ. First the code in the document source:
=item (This a special case, whichis always considered a definition)=item=item=item=item=item (A special case for the documentables)
Then the results on the rendered page:
How to use the þ infix(This is a special case, which is always considered a definition)
The þ Infix
trait is cached(A special case for the trait documentables)
These items should now be searchable by using the search field in the HTML docs.
You can add emphasis with bold ( B<> ) or italicized ( I<> ), with or without code formatting ( C<> ). Due to current parser limitations, special steps have to be taken to use X<> with other formatting codes; for example:
=item a fancy subroutine
renders like this
foo a fancy subroutine
Notice that text after a pipe ('|') has no formatting. Also note that C<> preserves spaces and treats text as verbatim.
