Website setup

Running locally (Windows and Mac)

The site is built with Jekyll, and is easy to run locally if you have Ruby.

If you don't have Ruby version 2.5.0 or higher installed, please see the "Standard Setup" sections below.

Open command prompt and browse to your website's folder. To set up a "bundle" (local virtual environment in Python terms):

bundle install

Next, use bundle exec to run a command in the new environment you just created, such as:

bundle exec jekyll serve

This will incrementally rebuild if there were anything changes in your directory. Using an internet browser, browse to the server address shown in the output, e.g.: http://127.0.0.1:4000.

To stop the server, press Control+C.

Setup for local development

1. Standard setup (Mac)

Visit this page for information about installing Ruby if your current version is too old; the instructions there form the basis for what you see here, and come in variants for all major operating systems. You should have Ruby 2.4+ for Jekyll. Since versions of macOS before Catalina with 2.3 (and Apple is dropping scripting language from macOS in the future), you may want a newer version even on a mac. You can use rbenv to manage multiple ruby versions. On macOS with homebrew, you'll want:

brew install rbenv

You'll need to run:

rbenv init
# Prints out instructions

and follow the instructions for your current shell. After you've installed rbenv on your system, use:

rbenv install 2.7.0

to get a current version of ruby. Then, inside the main iris-hep website directory, run:

rbenv local 2.7.0

This will run the Ruby you just built whenever you enter this directory. You'll want to install bundler too:

gem install bundle

(You may want to add --user-install here if you are not using rbenv. And if you don't have permission to install, and you are using rbenv, this means you forgot to set it up with rbenv init.)

2. Standard setup (Windows)

Jekyll is a Ruby Gem that can be installed on most systems. Please view the official installation instructions for Windows, or follow the below steps.

• Download and install a Ruby+Devkit version from RubyInstaller Downloads.

• Use default options for installation.

• Run the ridk install step on the last stage of the installation wizard.

• This is needed for installing gems with native extensions.

• From the options choose MSYS2 and MINGW development tool chain.

• On a new command prompt, type the following to enable it:

ridk enable

• Open a new command prompt window from the start menu, so that changes to the PATH environment variable becomes effective.

• Open command prompt and browse to your website's folder.

• Install Jekyll and Bundler using:

gem install jekyll bundler

• Check if Jekyll has been installed properly:

bundle exec jekyll -v

You may receive an error when checking if Jekyll has not been installed properly. Reboot your system and run jekyll -v again.

3. Docker setup

If you use docker, the following line will build and serve the site locally:

docker run --rm -v "$PWD:/srv/jekyll" -p 4000:4000 -it jekyll/jekyll:3.8 jekyll serve

If you want to enable LiveReload (pages automatically reload when jekyll rebuilds after detecting changes), then use this instead:

docker run --rm -v "$PWD:/srv/jekyll" \
           -p 4000:4000 -p 35729:35729 \
           -it jekyll/jekyll:3.8 \
           jekyll serve --livereload
