Upgrading from an older version of Jekyll? A few things have changed in 1.0.
### The Jekyll Command
For better clarity, Jekyll now accepts the commands `build` and `serve`.
Whereas before you might simply run the command `jekyll` to generate a site
and `jekyll --serve` to view it locally, now use the subcommands `jekyll build`
and `jekyll serve` to do the same. And if you want Jekyll to automatically
rebuild each time a file changes, just add the `--watch` flag at the end.
### Custom Config File
Rather than passing individual flags via the command line, you can now pass an
entire custom Jekyll config file. This helps to distinguish between
environments, or lets you programmatically override user-specified defaults.
Simply add the `--config` flag to the `jekyll` command, followed by the path
to one or more config files.
<div class="note info">
<h5 mardown="1">The `--config` flag overrides your `_config.yml` file</h5>
<p markdown="1">If you use the `--config` flag, Jekyll will ignore your
`_config.yml` file. Want to merge a custom configuration with the normal
configuration? No problem. Jekyll will accept more than one custom config
file via the command line. Simply pass the path to both files with the latter
file overriding the former.</p>
</div>
#### As a result, the following command line flags are now deprecated:
* `--no-server`
* `--no-auto`
* `--auto` (now `--watch`)
* `--server`
* `--url=`
* `--maruku`, `--rdiscount`, and `--redcarpet`
* `--pygments`
* `--permalink=`
* `--paginate`
### Draft posts
Jekyll now lets you write draft posts, and allows you to easily preview how
they will look prior to publishing. To start a draft, simply create a folder
called `_drafts` in your site's source directory (e.g., along side `_posts`),
and add a new markdown file to it. To preview your new post, simply run the
`Jekyll serve` command with the `--drafts` flag.
<div class="note info">
<h5 mardown="1">Drafts don't have dates</h5>
<p markdown="1">Unlike posts, drafts don't have a date, since they haven't
been published yet. Rather than naming your draft something like
`2013-07-01-my-draft-post.md`, simply name the file what you'd like your
post to eventually be titled, here `my-draft-post.md`.</p>
</div>
### Baseurl
Often, you'll want the ability to run a Jekyll site in multiple places, such as
previewing locally before pushing to GitHub pages. Jekyll 1.0 makes that easier
with the new `--baseurl` flag. Throughout your Jekyll site, simply prefix
relative urls with `{{ site.baseurl }}` and add the production `baseurl` to
your `_config.yml` file. When previewing locally, Jekyll will swap in whatever
you pass along via the `--baseurl` flag (most likely `/`), ensuring your links
remain true in both environments.
