This repository contains the Asciidoc source and the toolchain to build the Raspberry Pi Documentation. For details of how to contribute to the documentation see the CONTRIBUTING.md file.
NOTE: This repository has undergone some recent changes. See our blog post for more details.
Instructions on how to checkout the documentation repo, and then install the toolchain needed to convert from Asciidoc to HTML and build the documentation site.
Install git if you don't already have it, and check out the documentation repo as follows,
$ git clone https://github.com/raspberrypi/documentation.git
$ cd documentation
This works on both regular Debian or Ubuntu Linux — and has been tested in a minimal Docker container — and also under Raspberry Pi OS if you are working from a Raspberry Pi.
You can install the necessary dependencies on Linux as follows,
$ sudo apt install -y ruby ruby-dev python3 python3-pip make ninja-build
then add these lines to the bottom of your $HOME/.bashrc,
export GEM_HOME="$(ruby -e 'puts Gem.user_dir')"
export PATH="$PATH:$GEM_HOME/bin"
and close and relaunch your Terminal window to have these new variables activated. Finally, run
$ gem install bundler -v 2.2.15
to install the latest version of the Ruby bundle command.
If you don't already have it installed you should go ahead and install HomeBrew,
$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Then you need to install Ruby,
$ brew install ruby@2.7
$ gem install bundler -v 2.2.15
NOTE: Homebrew defaults to Ruby 3.0 which is incompatible with Asciidoctor.
IMPORTANT: Homebrew has problems using /bin/zsh, you may have to change your default shell to /bin/bash.
If you're using csh or tcsh add the following lines to your .cshrc or .tcshrc,
setenv PATH /usr/local/bin:/usr/local/sbin:$PATH
setenv PATH /usr/local/opt/ruby/bin:${PATH}
setenv PATH ${PATH}:/usr/local/lib/ruby/gems/2.7.0/bin
setenv LDFLAGS -L/usr/local/opt/ruby@2.7/lib
setenv CPPFLAGS -I/usr/local/opt/ruby@2.7/include
setenv PKG_CONFIG_PATH /usr/local/opt/ruby@2.7/lib/pkgconfig
or if you're using bash add the following lines to your .bash_profile,
export PATH="/usr/local/bin:/usr/local/sbin:$PATH"
export PATH="/usr/local/opt/ruby/bin:$PATH"
export PATH="$PATH:/usr/local/lib/ruby/gems/2.7.0/bin"
export PATH="/usr/local/opt/ruby@2.7/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/ruby@2.7/lib"
export CPPFLAGS="-I/usr/local/opt/ruby@2.7/include"
export PKG_CONFIG_PATH="/usr/local/opt/ruby@2.7/lib/pkgconfig"
NOTE: If you are running macOS on an Apple Silicon based Mac, rather than an Intel Mac, substitute /opt/homebrew/ for /usr/local in the lines dealing with ruby@2.7 in the above block.
and then open a new Terminal window to make sure you're using the right version of Python and Ruby.
Go ahead and brew install the other dependencies,
$ brew install python@3
$ brew install ninja
$ brew install gumbo-parser
$ pip3 install pyyaml
After you've installed the toolchain (on either Linux or macOS), you'll need to install the required Ruby gems and Python modules. Make sure you're in the top-level documentation/ directory (i.e. the one containing Gemfile.lock and requirements.txt) and then run,
$ bundle install
(which may take several minutes), followed by,
$ pip3 install --user -r requirements.txt
After you've installed both the toolchain and scripting dependencies, you can build the documentation with,
$ make
This will automatically use Ninja build to convert the source files in documentation/asciidoc/ to a suitable intermediate structure in build/jekyll/, and then use Jekyll AsciiDoc to convert the fi
7F55
les in build/jekyll/ to the final output HTML files in documentation/html/.
You can also start a local server to view the built site by running,
$ make serve_html
As the local server launches, the local URL will be printed in the terminal -- open this URL in a browser to see the locally-built site.
You can revert your repository to a pristine state by running,
$ make clean
which will delete the build/ and documentation/html/ directories.
If you want to build the Pico C SDK Doxygen documentation alongside the main documentation site you can do so with,
$ make build_doxygen_doc
$ make
and clean up afterwards by using,
$ make clean_everything
which will revert the repository to a pristine state.
