Supported platforms

J1 is supported on all current x64-based OS:

  • Windows 10, build >= 1903
  • Windows WSL 2
  • Linux, Kernel version >= 4.15 (e.g. Ubuntu 18.x LTS)
  • OSX, version >= 10.10.5 (Yosemite)

Note that 32-bit versions (x32) are generally not supported for all platforms.

Development languages and tools

To run the Development System for J1 Theme, the following languages and tools expected to be in place with your OS:

  • Ruby language, version >= 2.7
  • Python language, version > 2.7 (optional) <1>
  • Javascript language (NodeJS), version >= 14.x < 15.x
  • Git, version >= 2.29 (optional) <2>
  • Jekyll, version 4.2.x

<1> Required only for full Jupyter Notebook support. <2> Required only if J1 Projects should be managed as repos.

NOTE: More current or older versions may work, but not tested.

Development packages

For some of the components J1 is using, a working C/C++ development environment is needed to compile platform-specific libraries. Ensure that all dev packages are installed for your OS (Linux, OSX, or Windows).

Development packages for Windows

For Ruby on Windows, a installation using RubyInstaller is recommended. A current Ruby of version 3.1 is available at the RubyInstaller V31 site. Note, to automatically install a development environment for Ruby on Windows, a version of Ruby should be installed that is already bundled with a DEVKIT (MSYS2 toolchain).

Development packages on Linux (Ubuntu)

In order to install all required development components on e.g. Ubuntu you run:

sudo apt-get -y install \
gcc g++ make \
autoconf bison build-essential \
libssl-dev \
libyaml-dev \
libreadline-dev \
zlib1g-dev \
libncurses5-dev \
libffi-dev \
libgdbm-dev

To install the required languages and tools, if not already in place, the following commands can be used to do so:

sudo apt-get -y install \
curl \
git-all \
nodejs \
ruby

Additionally, for Ruby and NodeJS the dev-packages are to be installed to make all header files available for a working C/C++ development environment:

sudo apt-get -y install \
nodejs-dev \
ruby-dev

Note that priviliged (administrative) user rights are needed to install system-wide software packages for Ruby and the OS.

Development packages on OSX

For all OSX system, the installation of the Apple Developer Tools (XCode) is expected. Development tools like Ruby, NodeJS, or the bash comes with the OS are not recommended to use. Most of the software comes in quite old versions and therefor unusable for J1 development.

To install recommended versions, the easiest way to install the missing software is Homebrew. A lot of helpful information how to manage package installations using Homebrew can be found on the internet.

Beside the base installation of the recommend tools, all other recommendations for Linux systems are for OSX the same.

Upgrades needed for all platforms

If Ruby and NodeJS are in place, some packeages are to be upgraded to more current versions. Install all packages system-wide with their respective product installation pathes.

Upgrades needed for Ruby <= v2.7

Install latest bundler for Ruby:

gem install bundler --no-document

Install latest RubyGems for Ruby:

gem install rubygems-update --no-document
update_rubygems --no-document
gem update --system

Upgrades needed for NodeJS

NodeJS comes with NPM pre-installed. The native CLI for the NodeJS package management is npm. Besides npm there's another quite handy CLI for NPM available: Yarn.

The CLI yarn is developed at Facebook and can be used as a replacement for npm. From a top-level perspective, both package management clients behave pretty much the same. The syntax yarn uses is shorter in writing, making the command-line look a bit more natural. Therefore, we prefer to use yarn.

NOTE: Yarn adds some additional features to the NodeJS package management implemented for the needs at Facebook. To use J1 Theme, those add-ons are neither needed nor used.

Install latest NPM and Yarn packages for NodeJS:

npm install -g npm@latest
npm install -g yarn@latest

Managing J1 Projects

Managing J1 Theme projects is very simple:

  • Install J1 Theme
  • Setup a project
  • Initialize the project
  • Run the J1 Project

Install J1 Theme

You can install J1 Theme in two ways:

  • Installing the Ruby Gem of J1 Theme (recommended)
  • Clone the current J1 Theme Repo from Github

The recommended method to install J1 is using the the Ruby Gem. If you're using Git already, cloning the Repo at Github may an option.

Installing the Ruby Gem

It is highly recommended to install all project-related Ruby GEMs so-called userized. The user install option of the RubyGems CLI gem will install all requested Ruby Gems in the home directory of a user. Installing userized prevents polluting the System Ruby Installation by packages only needed by specific users or projects.

IMPORTANT: If you're on Linux (Unix), a system-wide installation of Ruby GEMs requires elevated user rights (root). Userized installations of Ruby packages can be done by all users without having elevated user rights.

J1 Theme uses the user install option internally by default. All depended Ruby GEMs are installed in the user's home directory in folder .gem.

Prior to install the J1 Gem, make sure that a .gem folder already exists in your home directory.

On Windows, run:

mkdir %HOMEDRIVE%%HOMEPATH%\.gem

On Unix/linux, run:

md $HOME/.gem

The latest version of J1 Theme is available at RubyGems or can installed by the RubyGems CLI gem:

gem install j1-template --no-document --user-install

NOTE The installation of the Gem will resolve all dependencies and downloaad|install all dpended Ruby GEMs as required (userized).

Checkout the Repo from Github

The Repo for the latest version of J1 Theme is published on Github. You can get it by cloning the repository using Git`:

git clone https://github.com/jekyll-one/j1-starter

The repo gets written to folder j1-starter. Have a look and browse the folder. You'll see a structure like this:

General J1 Project Repo structure:

  ├──── j1-starter
  │    └─── _data
  |    └─── _includes
  │    └─── _plugins
  │    └─── assets
  │    └─── collections
  │    └─── dot.bundle  
  │    └─── pages
  ├──── dot.gitattributes
  ├──── dot.gitignore
  ├──── dot.ruby-version
  ├──── dot.nojekyll
  ├──── dot.ruby-version
  ├──── favicon.ico
  ├──── Gemfile
  ├──── index.html          
  ├──── LICENSE.md
  ├──── package.json
  └──── README.md

NOTE: It is recommended to rename the folder j1-template-starter of the cloned repo to a more specific (project) name.

All development tasks are defined as NPM scripts with the project config file package.json. For your convenience, the J1 Theme Gem comes with a build-in CLI j1 run all project-related commands; no need to learn npm or how to manage NodeJS projects.

Setup the Project

The setup procedure depends on how you installed J1 Theme. If you are using the J1 GEM as recommended, you need to create a personal project first. If you have cloned the J1 Theme Repo from Github, the project is already created by the clone's folder and you can skip the creation of a project; continue on section Initialize a J1 Project.

Create a J1 Project

First, you should make a folder holding all your J1 projects. On Windows, run:

mkdir %HOMEDRIVE%%HOMEPATH%\j1-projects

Managing J1 Projects is simple: all tasks you need are run by the buildin CLI j1. To create a new project inside the projects folder, run:

cd %HOMEDRIVE%%HOMEPATH%\j1-projects && j1 generate my-starter

This command creates a initial project in folder my-starter.

Initialize the project

To make a project usable, is has to be initialzed first. This is needed only once after you create a new project. On Windows, run the setup task like so:

cd %HOMEDRIVE%%HOMEPATH%\j1-projects\my-starter && j1 setup

NOTE: While initializing a project, the J1 Theme Gem is downloaded as a dependecy (if not already installed). For the users cloned the J1 Template repo (as a project), the J1 GEM will be installed and all j1 commands are available as well.

  Check consistency of the J1 project ...

Rebuild a project

For some reason, it may needed to re-create an existing project. The task rebuild rebuild all documents (pages and posts) from the scratch but leaves the base project files untouched. To reset a project, run (inside the project folder):

Reset a project

To start a project from the beginning, you can reset the system to the factory state. The task reset does the resetting work for you and cleans up each and everything except the Git repo and the modules folder node_modules stored in the project root. Both are kept untouched by a reset.

j1 reset

The cleanup runs some tasks for the root folder and in parallel sub-tasks using Lerna for all packages:
