Jekyll does not generate _posts

Question

I'm having trouble getting jekyll to convert a message to the _posts directory in html. It generates index.md correctly, but generates nothing for messages. When I add "source: _posts", it converts the message but does not convert index.md.

As far as I can tell, the "source" should either not be added to _config.yml, or it should point to "."

My directory structure is pretty standard:

 $ find. | fgrep -v bootstrap
 .
 ./index.md
 ./_config.yml
 ./_drafts
 ./_includes
 ./_includes/footer.html
 ./_includes/header.html
 ./_layouts
 ./_layouts/default.html
 ./_posts
 ./_posts/2013-02-02-test-blog.md
 ./_site
 ./_site/index.html

 $ cat _config.yml
 name: "Developer blog"
 description: ""

 url: "http: // localhost: 4000"
 source:.
 paginate: 10

 markdown: rdiscount
 permalink: pretty
 pygments: true
 auto: true

Even when I leave auto off, I do not see the stack trace.

 $ cat _posts / 2013--02-25-test-blog.md
 ---
 layout: default
 title: Testing a blog
 ---

 #test blog

 this is a test

Answer 1

_posts/2013--02-25-test-blog.md 

This is the wrong name.

Perhaps use this

 _posts/2013-02-25-test-blog.md
