Your patches to perl6/doc are very welcome.
This document describes how to get started and helps to provide documentation that adheres to the common style and formatting guidelines.
Your contributions will be credited in Rakudo release announcement. You name from the commit log will be used. If you'd like to be credited under a different name, please add it to CREDITS file
If you have any questions regarding contributing to this project, please ask in the #perl6 IRC channel.
- General principles
- Documenting types
- Writing and Testing Examples
- Debug mode
- Reporting bugs
- Building the documentation
- Please use the present tense, and active voice.
- Link to external resources (like Wikipedia) for topics that are not directly related to Perl 6 (like the math that our routines implement)
- Duplicate small pieces of information rather than rely on linking
- Be explicit about routine signatures. If a method accepts a
*%args
, but treats some of them specially, list them separately. - Check out the styleguide for further guidance
- For website: we support the current and previous major releases of Chrome, Firefox, Internet Explorer (Edge), and Safari. Please test layout changes. Lacking actual browsers to test in, you can use browsershots.org or browserstack.com. Ensure the layout looks OK on mobile.
The POD documentation of types is located in the doc/Type
directory and
subdirectories of this repository. For example the POD of X::Bind::Slice
lives in doc/Type/X/Bind/Slice.pod6
.
To start contributing fork and checkout the repository, find the document you want to improve, commit your changes, and create a pull request. Should questions come up in the process feel free to ask in #perl6 IRC channel.
If the documentation for a type does not exist, create the skeleton of the doc
with the helper tool util/new-type.p6
. Say you want to create MyFunnyRole
:
$ perl6 util/new-type.p6 --kind=role MyFunnyRole
Fill the documentation file doc/Type/MyFunnyRole.pod6
like this:
=TITLE role MyFunnyRole
=SUBTITLE Sentence or half-sentence about what it does
role MyFunnyRole does OtherRole is SuperClass { ... }
Longer description here about what this type is, and
how you can use it.
# usage example goes here
=head1 Methods
=head2 method do-it
method do-it(Int $how-often --> Nil:D)
Method description here
MyFunnyRole.do-it(2); # OUTPUT: «example output»
When documenting a pair of a sub and a method which both do the same thing, the
heading should be =head2 routine do-it
, and the next thing should be two or
more lines with the signatures. Other allowed words instead of method
are
sub
, trait
, infix
, prefix
, postfix
, circumfix
, postcircumfix
,
term
. If you wish to hide a heading from any index prefix it with the empty
comment Z<>
.
When providing a code example result or output, use this style:
# For the result of an expression.
1 + 2; # RESULT: «3»
# For the output.
say 1 + 3; # OUTPUT: «3»
# For the explanatory comment
do-work; # We call do-work sub
Any contributions should pass the make test
target. This insures basic
integrity of the documentation, and is run automatically by a corresponding
travis build. Even edits made via the GitHub editor should pass this test.
The repo should also pass make xtest
most of the time - this includes
tests about whitespace and spelling that might be difficult to get right
on an initial commit, and shouldn't be considered to break the build. If
you're contributing a patch or pull request, please make sure this passes.
See Writing and Testing Examples
To get a list of methods that are found via introspection but not found in any
pod6 under doc/Type/
, use util/list-missing-methods.p6
. It takes a
directory or filepath as argument and limits the listing to the given file or
any pod6-files found. All methods listed in util/ignored-methods.txt
are
ignored.
On the right side of the footer you can find [Debug: off]. Click it and reload
the page to activate debug mode. The state of debug mode will be remembered by
window.sessionStorage
and will not survive a browser restart or opening the
docs in a new tab.
You can create index entries and invisible anchors with X<|thing,category>
.
To make them visible activate debug mode.
If you change the layout please check different screen sizes. Debug mode will display the viewport size in the bottom left corner.
To check for broken links use debug mode. Any spotted broken link will be listed under the search input. Please note that some external links may not get checked depending on your browser settings.
Please check if the headings you add are of sound structure. You can use debug mode to display heading numbers.
Report issues at https://github.com/perl6/doc/issues. You can use the following labels when tagging tickets:
- site - presentation issue with the website (e.g. invalid HTML)
- docs - missing or incorrect documentation (use 'NOTSPECCED' instead, if this is for a feature present in a compiler, but not in the Perl 6 test suite)
- new - this is a new doc item that requires fresh text
- update - this is an existing doc item that requires some analysis or editing
- build - scripts or libraries that generate the site
- search - the search component, either for items that are on the site but not searchable, or for search functionality)
Contributors may also specify one of the following tags.
- LHF - for a beginner to work on
- big - a big issue, requires research or consensus
If you would like to contribute documentation or other bug fixes, please use github's Pull request feature.
Assuming that you have already forked and cloned the perl6/doc repository, one of the first things you probably want to do is to build the documentation on your local computer. To do this you will need:
- Perl 6 (e.g., the Rakudo Perl 6 implementation)
- zef (the installer for third party Perl 6 modules)
Pod::To::HTML
(Perl 6 module for converting Pod objects to HTML)- graphviz (
sudo apt-get install graphviz
on Debian/Ubuntu) - Mojolicious (optional; a Perl 5 web framework; it allows you to run a web app locally to display the docs)
- SASS Compiler
- highlights (optional; requires
nodejs
,npm
, and at least GCC-4.8 on Linux to be installed. Runningmake
will set everything up for you.)- Debian instructions:
- Get more modern nodejs than in repos:
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
- Run
make init-highlights
to initialize highlights - If that still isn't working try running
npm install node-gyp -g
and try running make command again
- Get more modern nodejs than in repos:
- Debian instructions:
You need Perl 6 installed. You can install the Rakudo Perl 6 compiler by downloading the latest Rakudo Star release from rakudo.org/downloads/star/
Zef is a Perl 6 module installer. If you installed Rakudo Star package, it should already be installed. Feel free to use any other module installer for the modules needed (see below).
The program that builds the HTML version of the documentation
(htmlify.p6
) uses Pod::To::HTML
to convert Pod structures into HTML.
You'll also need Pod::To::BigPage
. Install these modules like so:
$ zef install Pod::To::HTML Pod::To::BigPage
This is a Perl 5 web framework which is used to run the included web application that displays the HTML documentation in a web browser. It's no required for development, as the site is static and you can serve it using any other webserver.
The app does automatically convert the SASS file to CSS, so it's handy to use for that as well.
Mojolicious is written in Perl 5, so assuming that you use
cpanm
,
install this now:
$ cpanm -vn Mojolicious
To build the styles, you need to have a SASS compiler. You can either install
the sass
command
$ sudo apt-get install ruby-sass
or the CSS::Sass Perl 5 module
$ cpanm -vn CSS::Sass Mojolicious::Plugin::AssetPack
The SASS files are compiled when you run make html
, or make sass
, or
start the development webserver (./app-start
).
To actually build the documentation all you now need to do is run
htmlify.p6
:
$ perl6 htmlify.p6
This takes a while, but be patient!
After the build has completed, you can start the web application which will render the HTML documentation
$ perl app.pl daemon # note! Perl 5 *not* Perl 6 here
Now point your web browser to http://localhost:3000 to view the documentation.
