jtasks: a swiss knife for Jekyll projects

jtasks (Jekyll tasks) is a collection of configurable Invoke tasks that provide simple, but powerful, interface to run both common and advanced routines in your Jekyll projects.

For example, let's run development server via Bundler, at host 0.0.0.0 (like in Jekyll 2), port 5000 (because I have multiple Jekyll projects served simultaneously), generate output into dist folder, including drafts and enabling incremental build:

# using jtasks:
$ invoke serve -bdi

# common way:
$ bundle exec jekyll serve --destination ./dist/ --host 0.0.0.0 --port 5000 --incremental --drafts

--destination, --host and --port are configured as global variables at the settings part of the script. This allows flexible setup of jtasks on per-project basis.

How to Use

inv[oke] task1 [--task1-opts] ... taskN [--taskN-opts]

Examples:

Build the site with Bundler:

$ inv build -b

Serve site with Bundler including draft posts:

$ inv serve -bd

Notify Google and Bing about your sitemap updates:

$ inv notify -gb

Create a new post with the given title:

$ inv post "My awesome post"

Start development server and fire up default browser to preview resulted site:

$ inv serve preview

List all posts and drafts:

$ inv list -d

Remove generated site:

$ inv clean

Check site for compatibility problems and URL conflicts:

$ inv doctor

Installation

Copy tasks.py file into the base folder of your Jekyll site.

You also need Python (2.7+ or 3.3+) with Invoke package:

• Install Python
• Install Invoke

Configuration

All settings are available at the top of the tasks.py file:

# === Settings ===

# Project directories
_site_dest = "./_site/"       # Dir where Jekyll will generate site
_posts_dest = "./_posts/"     # Dir with posts
_drafts_dest = "./_drafts/"   # Dir with drafts

# Global options
_hostname = '127.0.0.1'       # Listen given hostname
_port = '4000'                # Listen given port
_bundle_exec = False          # Run commands with Bundler
_fpolling = False             # Force watch to use polling
_incremental = False          # Enable incremental build (Jekyll 3 and higher!)

# Post settings
_post_ext = '.md'             # Post files extension

# Notification settings (your sitemap location)
_sitemap_url = 'http://www.example.com/sitemap.xml'

From the box, jtasks uses Jekyll 3 default configuration settings. They can be easily modified for your project-specific needs. E.g. if we always need to run all tasks via Bundler, it is possible to set _bundle_exec = True and now all tasks (where applicable) will be executed using bundle exec:

$ inv build

# Same as:
$ bundle exec jekyll build --destination ./_site/
