About HackageDB
HackageDB is a collection of released Haskell packages. Each package is in the Cabal format, a standard way of packaging Haskell source code that makes it easy to build and install. (HackageDB and Cabal are components of a broader Haskell infrastructure effort called Hackage.) These pages are a basic web interface to the Hackage package database.
Finding packages
The Packages link above lists the available packages and provides a full text search of the package pages (via Google), while What's new lists recent additions (also available as an RSS feed). Hayoo! provides an API search.
See How to install a Cabal package for instructions on installing the packages you find here. There is also an experimental command-line tool that makes this easier.
You can report and problems with a package to the address given in the Bug-Reports or Maintainer field of its .cabal file.
Releasing packages through HackageDB
To upload your own releases, you'll first need to package them as Cabal source packages. See How to create a Haskell package for a tutorial. You can check and upload your package using the Upload link above, though to upload packages you'll need a HackageDB username and password (see User accounts).
Getting the raw data
- upload log (240KB)
- tarball of package descriptions (900KB)
- archive of the latest version of all the packages (80MB tar file)
