Jekyll is used to generate HTML files from the markdown + templates in this repository. The built version of the site is kept on the asf-site branch, which gets deployed to https://arrow.apache.org.

To add a blog post, create a new markdown file in the _posts directory, following the model of existing posts. In the front matter, you should specify an "author". This should be your Apache ID if you have one, or it can just be your name. To add additional metadata about yourself (GitHub ID, website), add yourself to _data/contributors.yml. This object is keyed by apacheId, so use that as the author in your post. (It doesn't matter if the ID actually exists in the ASF; all metadata is local to this project.)

With Ruby >= 2.1 installed, run the following commands to install Jekyll.

gem install jekyll bundler
bundle install

On some platforms, the Ruby nokogiri library may fail to build, in such cases the following configuration option may help:

bundle config build.nokogiri --use-system-libraries

nokogiri depends on the libxml2 and libxslt1 libraries, which can be installed on Debian-like systems with

apt-get install libxml2-dev libxslt1-dev

Run the following to generate HTML files and run the web site locally.

bundle exec jekyll serve

On commits to the master branch of apache/arrow-site, the rendered static site will be published to the asf-site branch using GitHub Actions. On a fork, it will deploy to your gh-pages branch for deployment via GitHub Pages; this is useful for previewing changes you're proposing. To enable this deployment on your fork, you'll need to sign up for GitHub Actions here.

To update the documentation, you can run the script ./dev/gen_apidocs.sh in the apache/arrow repository. This script will run the code documentation tools in a fixed environment.

First, build Apache Arrow C++ and Apache Arrow GLib. This assumes that you have checkouts your forks of arrow and arrow-site alongside each other in your file system.

mkdir -p ../cpp/build
cd ../cpp/build
cmake .. -DCMAKE_BUILD_TYPE=debug
make
cd ../../c_glib
./autogen.sh
./configure \
  --with-arrow-cpp-build-dir=$PWD/../cpp/build \
  --with-arrow-cpp-build-type=debug \
  --enable-gtk-doc
LD_LIBRARY_PATH=$PWD/../cpp/build/debug make GTK_DOC_V_XREF=": "
rsync -r doc/reference/html/ ../../arrow-site/asf-site/docs/c_glib/

cd ../js
npm run doc
rsync -r doc/ ../../arrow-site/asf-site/docs/js

Then add/commit/push from the asf-site/ git checkout.
