Middleman Github Pages

Gem Version Gem Downloads

Middleman makes creating static sites a joy, Github Pages hosts static sites for free, Middleman Github Pages brings the two together. Middleman Github Pages is just a few rake tasks that automate the process of deploying a Middleman site to Github Pages.


Add this line to your Gemfile:

gem 'middleman-gh-pages'

You'll also need to require the gem in your Rakefile:

require 'middleman-gh-pages'


Middleman Github Pages provides the following rake tasks:

rake build    # Compile all files into the build directory
rake publish  # Build and publish to Github Pages

The only assumption is that you are deploying to a gh-pages branch in the same remote as the source. rake publish will create this branch for you if it doesn't exist.

Environment Variable Options


You cannot deploy your site if you have uncommitted changes, but you can override this (default: nil):

bundle exec rake publish ALLOW_DIRTY=true


You can append a custom suffix to commit messages on the build branch (default: nil):

bundle exec rake publish COMMIT_MESSAGE_SUFFIX="[skip-ci]"


You can change the remote that you deploy to (default: origin):

bundle exec rake publish REMOTE_NAME=upstream


If you're publishing a personal or organization page, you may want to use the branch master instead of gh-pages (default: gh-pages):

bundle exec rake publish BRANCH_NAME=master


If your middleman project isn't at the root of your repository, you will likely need to change this (default: root of git repository):

bundle exec rake publish PROJECT_ROOT=/Users/me/projects/repo/www


If you override the default middlemant :build_dir setting, you will likely also need to set this variable (default: <PROJECT_ROOT>/build):

bundle exec rake publish BUILD_DIR=/some/custom/path/to/public

Setting ENV variables from your Rakefile

Of course, for more permanent settings, you can always set these environment variables directly in your Rakefile instead of from the command line.

require "middleman-gh-pages"

# Ensure builds are skipped when publishing to the gh-pages branch
# Ignore errors about dirty builds (not recommended)
ENV["ALLOW_DIRTY"] = "true"

Custom Domain

To set up a custom domain, you can follow the GitHub help page.

NOTE You will need to put your CNAME file in the source directory of your middleman project, NOT in its root directory. This will result in the CNAME file being in the root of the generated static site in your gh-pages branch.

Project Page Path Issues

Since project pages deploy to a subdirectory, assets and page paths are relative to the organization or user that owns the repo. If you're treating the project pages as a standalone site, you can tell Middleman to generate relative paths for assets and links with these settings in the build configuration in config.rb

activate :relative_assets
set :relative_links, true

NOTE This only affects sites being accessed at the username.github.io/projectname URL, not when accessed at a custom CNAME.
