Some Octopress Rake Tips

— 5 minute read
It looks like you've found one of my older posts 😅 It's possible that some of the information may be out of date (or just plain wrong!) If you've still found the post helpful, but feel like it could use some improvement, let me know on Twitter.

This is a quick post just to scratch one of my own itches. I've been using Octopress every single day for around two months now and the generation time for my blog is slowly starting to creep up. I'd heard that you could isolate a post and just preview/generate it instead of doing the whole blog every time but it wasn't until today that I finally decided to look into it.

Turns out it's really simple. Let's say we are going through our usual steps of creating a new post:

rake new_post["Today is a Wonderful Day"]

Now that we have our post ready we can isolate it from all the others:

rake isolate[wonderful-day]

Notice I didn't pass in the entire filename? That's because the Rake task inspects each of our posts and stashes anything that doesn't include the String 'wonderful-day' in the filename.

Dir.glob("#{source_dir}/#{posts_dir}/*.*") do |post| post, stash_dir unless post.include?(args.filename)

Now that our post is isolated we can preview it, like we always do:

rake preview

Write a little bit, save, and hit localhost:4000 to see your super speedy blog post!

When we're all done we integrate the post back in with the rest of our blog.

rake integrate

And finally we generate and deploy it, which can be done in a single command:

rake gen_deploy

There are a few other useful rake tasks, you can see the whole list by running:

rake -T

rake clean # Clean out caches: .pygments-cache, .gist-cache, .sass-cache
rake copydot[source,dest] # copy dot files for deployment
rake deploy # Default deploy task
rake gen_deploy # Generate website and deploy
rake generate # Generate jekyll site
rake install[theme] # Initial setup for Octopress: copies the default theme into the path of Jekyll's generator.
rake integrate # Move all stashed posts back into the posts directory, ready for site generation.
rake isolate[filename] # Move all other posts than the one currently being worked on to a temporary stash location (stas...
rake list # list tasks
rake new_page[filename] # Create a new page in source/(filename)/index.markdown
rake new_post[title] # Begin a new post in source/_posts
rake preview # preview the site in a web browser
rake push # deploy public directory to github pages
rake rsync # Deploy website via rsync
rake set_root_dir[dir] # Update configurations to support publishing to root or sub directory
rake setup_github_pages[repo] # Set up _deploy folder and deploy branch for Github Pages deployment
rake update_source[theme] # Move source to source.old, install source theme updates, replace source/_includes/
rake update_style[theme] # Move sass to sass.old, install sass theme updates, replace sass/custom with sass.old/custom
rake watch # Watch the site and regenerate when it changes

I'm looking forward to trying out Octopress 2.1 as it includes a more streamlined generate task as well as some other nifty features. - Rob
