herald is a standalone application that automates publishing release notes to any Posterous site, but especially It transforms notes from Markdown to HTML using Knockoff, and posts them using Dispatch.


Install herald using conscript:

cs n8han/herald

Notes Specification

Release notes for your project are expected under a notes/ directory in the root of the project that mixes in the posterous.Publish trait. In this directory, notes for a particular version are named <version>.markdown while an optional short description about the project can be placed in about.markdown. For example, in posterous-sbt you'll find the following:


When publishing and previewing, the description from about.markdown is appended to the selected version's release notes as boilerplate.

If you're publishing to the Scala software announcement site, please keep in mind that the post's title will be the name of your project and its corresponding version: these should not be repeated as a heading in the notes. It is best to lead with copy describing the big changes in your release, or jump right into a list of those changes. For major releases with changes divided into sections, use an h3 (a line prefixed by ### in Markdown) or smaller heading. The short description about.markdown should be one or two sentences long, with a link to more information about your project.


You can preview your release notes for any project by running herald in its base directory. Herald assumes the notes you want to work with are the highest numbered ones in your notes directory.
