ProDOS-8 Website

Requirements for editing the site

For editing HTML files-only

• Just a text editor like that respects UNIX newline characters and won't insert a bunch of Windows return chars or old Mac line-endings.
• Decent editors would include things like: vim, nano, Atom, or Sublime Text

Required for building and serving locally

• The site is built using Jekyll, the static website builder.
• Jekyll allows the site to built dynamically, but served statically.
• A static site makes it easy to host, on something like AWS S3+CloudFront.
• The static site is lightning fast to load as there isn't any server-side processing of the page.
• To build the site you will need to have Jekyll installed.
• Jekyll is a ruby-based app, so Ruby will need to be installed to support Jekyll.
• Not all versions of Ruby are created equal, so ensure Ruby is a recent version using RVM.

rvm osx-ssl-certs
rvm list known | grep "^\[ruby-\]"
rvm install ruby-2.4.1
rvm list
rvm use ruby-2.4.1

gem install bundler jekyll

Required for rebuilding the CSS using SASS

• SASS is a CSS pre-compiler.
• SASS allows CSS to be built in a sophisticated way allowing re-usable code instead of having redundancies everywhere.
• The CSS is compiled from the source in the _scss directory using the sass precompiler.
• SASS is javascript based and requires NodeJS to be installed.
• After installing NodeJS, using npm to install all the dependencies:

npm install

Making changes to the Navigation Bar

• The data for what goes in to the navigation bar come from _data/navigation.yml.
• edit navigation.yml appropriately and the primary navigation will change.
• The primary navigation is rendered by _includes/header.html which reads in the variable site.data.navigation set within _data/navigation.yml.
• Only edit _includes/header.html if you want to change the formatting of how the navbar appears.
  Edit _data/navigation.yml to change the contents of that navbar.

Changing the home page content, slides, and promos

• The content of the homepage comes from: _layouts/home.html
• Jekyll uses layouts to determine what a page format will look like.
• All pages, that are not the home page, use the page layout.
  The home page has its own custom home layout to accommodate how the page is different.
• The layout itself is capable of using another layout, and so the home and page layouts both include the default layout, which holds the overall site wrapper.

Using Gulp to perform functions in a repeatable way

Using Gulp

• List the available gulp tasks:

gulp --tasks
gulp --tasks-simple

Running just gulp will compile the sass and compile the jekyll site

gulp

Compile files from _scss into both _site/css (for live injecting) and site (for future jekyll builds)

gulp sass

Compile and minify Javascript into one bundle file

gulp js

Building and Viewing the website locally

Jekyll can build the site

jekyll build

• After running the build command, the site contents will be in the _site directory.
• The contents of the _site directory are what would be hosted on something like S3:

aws s3 sync _site/ s3://prodos8.com/

• GitHub Pages are Jekyll aware, and will take the _site directory content to populate a hosted page.

Jekyll can serve the site

jekyll serve

• After running the serve command, Jekyll will start a webserver running on port 4000.
• Point your web browser to http://0.0.0.0:4000/ to view the site.
• The site you see should look something like this:

Publishing to staging using s3_website

• s3_website is a tool designed to publish the _site directory, that Jekyll creates, to S3 and optionally perform invalidations on cloudfront.

Install s3_website

• s3_website is a Ruby-based command that must be installed using gem

gem install s3_website

s3_website configuration

• s3_website uses a configuration file, s3_website.yml, which is used by s3_website.

FILE: s3_website.yml

s3_id:     <%= ENV['AWS_ACCESS_KEY_ID'] %>
s3_secret: <%= ENV['AWS_SECRET_ACCESS_KEY'] %>
s3_bucket: prodos8-staging

gzip:
  - .html
  - .css
  - .md
gzip_zopfli: false

AWS Environment Variables

• The s3_website.yml configuration file expects to pull the AWS credentials from two environment variables: AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
• The easiest way to populate those environment variables is to place them in the ~/.bash_profile.

FILE: ~/.bash_profile

export AWS_ACCESS_KEY_ID="AKIxxxxxxxxxxxxx"
export AWS_SECRET_ACCESS_KEY="xxxxxxxxxxxx"
export AWS_REGION="us-east-1"
export AWS_DEFAULT_REGION="us-east-1"

• The variables can be set before running s3_website

export AWS_ACCESS_KEY_ID="AKIxxxxxxxxxxxxx"
export AWS_SECRET_ACCESS_KEY="xxxxxxxxxxxx"

s3_website push

Use s3_website to publish

• With the environment variables set, run the s3_website push command

export AWS_ACCESS_KEY_ID="AKIxxxxxxxxxxxxx"
export AWS_SECRET_ACCESS_KEY="xxxxxxxxxxxx"

s3_website push

Sync a fork of a repository to keep it up-to-date with the upstream repository.

This BIG-gotcha difference between Stash Bitbucket and GitHub

• BitBucket auto-syncs repo changes from the original to the forked repo.
• Which means once we merge something, everybody gets it automatically and just pulls the latest.
• However, GitHub does not do that.
• So your personal fork can get out of sync
• The instructions below will allow you to resync from the upstream master.

Configure a remote for a fork

• Before you can sync your fork with an upstream repository, you must configure a remote that points to the upstream repository in Git.
• You must configure a remote that points to the upstream repository in Git to sync changes you make in a fork with the original repository.
• This also allows you to sync changes made in the original repository with the fork.

##
## List the current configured remote repository for your fork.
##
git remote -v

# origin  git@github.com:DevoKun/ProDOS-8.github.io.git (fetch)
# origin  git@github.com:DevoKun/ProDOS-8.github.io.git (push)

##
## Specify a new remote upstream repository that will be synced with the fork.
##
git remote add upstream git@github.com:ProDOS-8/ProDOS-8.github.io.git

##
## Verify the new upstream repository you've specified for your fork.
##
git remote -v

# origin    git@github.com:DevoKun/ProDOS-8.github.io.git (fetch)
# origin    git@github.com:DevoKun/ProDOS-8.github.io.git (push)
# upstream  git@github.com:ProDOS-8/ProDOS-8.github.io.git (fetch)
# upstream  git@github.com:ProDOS-8/ProDOS-8.github.io.git (push)

Fetch from upstream and merge to local master

git fetch upstream

##
## If not on master, switch to master
## master is not the same as upstream/master
## upstream/master is on github
## master is local to your laptop
##
git branch
git checkout master
git branch
git merge upstream/master

Create a script to resync the branch for you

• Create the file: ~/bin/gitresync
• The contents will be:

git remote -v

git fetch upstream
git branch
git checkout master
git branch
git merge upstream/master
