# Open Hub theme by Ribose
Open Hub is a theme for Jekyll oriented towards presenting open efforts
such as open-source software and specifications in a navigable and elegant way.
Open Hub fits two types of sites:
that describe one individual project, and that combine projects into a hub.
See also: CI_OPS for how to set up automated build and deployment of the site
to AWS S3.

## Starting a site with this theme
### Getting started with Ruby
If you aren’t using Ruby often, the recommended way to install it is with RVM.
Refer to RVM docs and use it to install a reasonably fresh Ruby version,
let’s say 2.4.4.
### Start new Jekyll site
jekyll new my-open-hub
### Installing theme
Add this line to your Jekyll site's `Gemfile`,
replacing default theme requirement:
```ruby
gem 'jekyll-theme-open-hub'
```
Add this line to your Jekyll site's `_config.yml`,
replacing default theme requirement:
```yaml
theme: jekyll-theme-open-hub
```
(Jekyll’s default theme was “minima” at the time of this writing.)
Execute to install dependencies:
$ bundle
### Configuring site
Edit _config.yml to add necessary site-wide configuration options,
and add necessary files and folders to site contents. This step depends
on the type of site you’re creating: open hub or individual open project site.
Below sections explain core concepts of open project and hub, and go
into detail about how to configure a project or hub site.
### Building site
Execute to build the site locally and watch for changes:
$ bundle exec jekyll serve --host mysite.local --port 4000
This assumes you have mysite.local mapped, otherwise omit --host
and it’ll use localhost.
## Universal setup
These are applicable to both site types (hub and project).
- You may want to remove the default about.md page added by Jekyll,
as this theme does not account for its existence.
- Add following items to _config.yml:
```yaml
title: Site title
description: Site description
# The above two are used by jekyll-seo-tag for things such as
# `
` and ` ` tags, as well as elsewhere by the theme.
collections:
posts:
output: true
permalink: /blog/:month-:day-:year/:title/
pages:
output: true
permalink: /:name/
defaults:
- scope:
path: ""
values:
layout: default
- scope:
path: _posts
type: posts
values:
layout: post
plugins:
- jekyll-seo-tag
```
### Logo
Logo consists of a symbol and site name.
**Symbol** is basically an icon for the site.
Should look OK in dimensions of 30x30px, and fit inside a square.
Should be in SVG format (see also the SVG guidelines section).
Place the symbol in _includes/symbol.svg.
**Site name** displayed to the right of the symbol.
Limit the name to 1-3 words.
By default, the title you define in site config is used (for project site,
it is the name of the project).
Alternatively, you can place site name in _includes/title.html with custom HTML
or SVG. (In that case it must look good when placed in a 30px tall container,
and in case of SVG same SVG guidelines apply).
### Legal small text
You may want to supply _includes/legal.html with content like this:
```html
Copyright © 2018 MyCompany. All rights reserved.
Terms
Privacy
```
### Blog
Project sites and hub site can have a blog.
#### Index
Create blog index page as _pages/blog.html, with nothing but frontmatter.
Use layout called "blog-index", pass `hero_include: index-page-hero.html`,
and set `title` and `description` as appropriate for blog index page.
Example:
```yaml
---
title: Blog
description: >-
Get the latest announcements and technical how-to’s
about our software and projects.
layout: blog-index
hero_include: index-page-hero.html
---
```
#### Posts
Place posts under _posts and name files e.g.
`2018-04-20-welcome-to-jekyll.markdown`. This is typical Jekyll setup.
## Hub site
The hub represents your company or department, links to all projects
and offers a software and specification index.
Additional items allowed/expected in _config.yml:
```yaml
social:
links:
- https://twitter.com/RiboseUS
- https://github.com/riboseinc
# Since a hub would typically represent an organization as opposed
# to individual, this would make sense:
seo:
type: Organization
collections:
projects:
output: false
# ... (other collections)
```
### Project, spec and software data
See the section about project data structure.
In addition to that, _when used within hub site_ each project subdirectory
must contain a file "index.md" with frontmatter like this:
```yaml
title: Sample Awesome Project
description: >-
A sentence or two go here.
# Whether the project is included in featured three projects on hub home page
featured: true | false
home_url:
```
### Software index page
Create software index in _pages/software.html, with nothing but frontmatter.
Use layout called "software-index", pass `hero_include: index-page-hero.html`,
and set `title` and `description` as appropriate.
Example:
```yaml
---
title: Software
description: Open-source software developed with MyCompany’s cooperation.
layout: software-index
hero_include: index-page-hero.html
---
```
### Specification index page
Create spec index in _pages/specs.html, with nothing but frontmatter.
Use layout called "spec-index", pass `hero_include: index-page-hero.html`,
and set `title` and `description` as appropriate.
Example:
```yaml
---
title: Specifications
description: Because specifications are cool!
layout: spec-index
hero_include: index-page-hero.html
---
```
## Project site
When project is set up as a standalone site, _config.yml should include
site-wide `title` that is the same as project name.
Additional items allowed/expected in _config.yml:
```yaml
authors:
- name: Your Name
email: your-email@example.com
author: "Company or Individual Name Goes Here"
collections:
software:
output: true
permalink: /:name/
specs:
output: true
permalink: /:name/
# ... (other collections)
defaults:
- scope:
path: _software
type: software
values:
layout: product
- scope:
path: _specs
type: specs
values:
layout: spec
# ... (other defaults)
```
File layout is the same as described in the section
about shared project data structure, with _software and _specs directories
found in the root of your Jekyll site.
## Describing a project: shared data structure
Each project is expected to have a machine-readable and unique name, a title,
a description, a symbol, and one or more software products and/or specs.
Following data structure is shared and used to describe projects,
whether on hub home site or each individual project site:
- /
- _includes/
- symbol.svg
- _software/
- .md
- _specs/
- .md
### Software and specs
An open project serves as an umbrella for related
software products and/or specifications.
Each product or spec is described by its own .md file with frontmatter,
placed under _software/ or _specs/ subdirectory, respectively,
of your open project’s Jekyll site.
Note: even though they’re in different subdirectories, all software products and specs
within one project share URL namespace and hence must have unique names.
### Software product
YAML frontmatter specific to software:
```yaml
version: v1.2.3
docs_url: https://foobar.readthedocs.io/en/latest
stack: [Python, Django, AWS]
```
#### Documentation
**Recommended:** use a dedicated service supporting versioned and well-structured
multi-page docs, such as Read the Docs. You can link users to that documentation
using docs_url in software product’s frontmatter.
Otherwise, if this open project’s page will serve as the authoritative source
of documentation for the software product, documentation contents are expected
to follow frontmatter.
Keep in mind that project name and description from before
will be displayed by the theme first. Start with second-level header (##),
with installation instructions or quick-start guide.
### Specification
YAML frontmatter specific to specs:
```yaml
rfc_id: XXXX
```
Specs that are not hosted elsewhere (such as ietf.org for RFCs)
are expected to contain the actual specification content after frontmatter.
Start with second-level header (##).
### Symbol
Should look OK in dimensions of 30x30px, and fit inside a square.
Should be in SVG format (see also the SVG guidelines section).
Place the symbol in _includes/symbol.svg within project directory.
## SVG guidelines
- Ensure SVG markup does not use IDs. It may appear multiple times
on the page hence IDs would fail markup validation.
- Ensure root element specifies its viewBox,
but no width or height attributes.
- You can style SVG shapes using in site’s assets/css/style.scss.
## Content guidelines
- Project title: 1-3 words, capital case
- Project feature description: about 20-24 words, no markup
- Project, software, spec regular description: about 12 words, no markup
- Post title: 3–7 words
- Post excerpt: about 20–24 words, no markup
## Select layout reference
Normally you don’t need to specify layouts manually, except where
instructed in site setup sections of this document.
Commonly used layouts are:
- blog-index: Blog index page. Pages using this layout are recommended
to supply hero_include.
- post: Blog post
- software-index: Software index page (hub site only).
Suggested to supply hero_include.
Will show a list of software across projects within the hub.
- spec-index: Specification index page (hub site only).
Suggested to supply hero_include.
Will show a list of specs across projects within the hub.
- product: Software product (project site only)
- spec: Open specification (project site only)
### Page frontmatter
Typical expected page frontmatter is `title` and `description`. Those are
also used by jekyll-seo-tag plugin to add the appropriate meta tags.
Commonly supported in page frontmatter is the hero_include option,
which would show hero unit underneath top header.
Currently, theme supports _includes/index-page-hero.html as the only value
you can pass for hero_include (or you can leave hero_include out altogether).
## Style customization
To customize site appearance, create a file in your Jekyll site
under assets/css/style.scss with following exact contents:
```
---
---
@import '{{ site.theme }}';
```
You can define custom style rules after the import, and customize variables
before the import.
### Custom rules
One suggested custom rule would be to change the fill color for SVG paths
used for your custom site symbol to white, unless it’s white by default.
The rule would look like this:
```scss
.site-logo svg path {
fill: white;
}
```
### SASS variables
Following are the variables along with their defaults:
```scss
# Primary color—should be bright but dark enough to be readable,
# since some text elements are set using this color:
$primary-color: lightblue !default;
# Darker variation of primary color used for background on elements where
# text is set in white:
$primary-dark-color: navy !default;
# Bright color for accent elements, such as buttons (not yet in use).
# Text on those elements is set in bold and white, so this color
# should be dark enough:
$accent-color: red !default;
# Below are used for `background` CSS rule for top header, and for
# hero unit respectively. Gradients can be supplied.
$header-background: $primary-dark-color !default;
$hero-background: $primary-dark-color !default;
```
## Contributing
Bug reports and pull requests are welcome on GitHub
at https://github.com/riboseinc/jekyll-theme-open-hub.
This project is intended to be a safe, welcoming space for collaboration,
and contributors are expected to adhere
to the [Contributor Covenant](http://contributor-covenant.org) code of conduct.
## Theme development
Generally, this directory is setup like a Jekyll site. To set it up,
run `bundle install`.
To experiment with this code, add content (projects, software, specs)
and run `bundle exec jekyll serve`. This starts a Jekyll server
using this theme at `http://localhost:4000`.
Put your layouts in `_layouts`, your includes in `_includes`,
your sass files in `_sass` and any other assets in `assets`.
Add pages, documents, data, etc. like normal to test your theme's contents.
As you make modifications to your theme and to your content, your site will
regenerate and you should see the changes in the browser after a refresh,
like normal.
When your theme is released, only files specified with gemspec file
will be included. If you modify theme to add more directories that
need to be included in the gem, edit regexp in the gemspec.
### Building and releasing
To check your theme, run:
./develop/build
It’ll build Jekyll site and run some checks, like HTML markup validation.
To build new gem and push it to rubygems.org, run:
./develop/release
