(back-ends as enumeration)
Revision as of 06:28, 12 August 2008
Haskore is a set of Haskell modules for creating, analysing and manipulating music. Music can be made audible through various back-ends. (See below.) A more recent, but less stable version, is available as Darcs repository at http://darcs.haskell.org/haskore/.
Ideally you can compose a song once in Haskore, and then play it by several back-ends. Practically this is more difficult, since all back-ends have different functionality (otherwise there wouldn't be so many).
These back-ends are currently supported:
- Notation output (Lilypond, partially done in CAEC, see below).
- Realtime MIDI
There is no Haskore related mailing list, but Haskore related discussion is very welcome at the Haskell art mailing list.
3 Getting started
With a bit of hacking Haskore can run on several platforms. In fact most of the hassle is caused by Haskore being not properly split into small packages. In future Haskore should consist of a small core for music composition, analysis and manipulation and separate packages for connecting to various back-ends and separated real-time stuff.
The original Haskore was mainly developed on Windows, whereas the revised version was developed mainly in Linux. So least hassle is currently caused on Linux.
- http://www.haskell.org/pipermail/haskell-cafe/2008-August/045911.html - Some hacks to get Haskore running on Windows quickly. The right thing to do would be to factor out the real-time stuff, since it is in general hard to port.
3.2 Installation using cabal
Prerequisits: You should be able to fetch a package using darcs and configure/build/install it using cabal.
Step 0. Choose a folder where some haskell packages can be stored.
Step 1. Get the packages. If you have
cabal-install installed, you can install some packages
cabal install midi # this will also install non-negative, event-list cabal install markov-chain
Now install each PACKAGE from (non-negative, event-list, record-access, markov-chain, midi, haskore) manually that is still not installed.
darcs get http://darcs.haskell.org/PACKAGE
Step 2. Patch Haskore's cabal file: Cabal.patch in order to remove some dependencies that you may not need at start (e.g. SuperCollider support):
cd haskore darcs apply /path/to/cabal.patch
Step 3. Build and install the packages that you got by darcs. For each PACKAGE (in the order of above)
cd PACKAGE runhaskell Setup.lhs configure (--prefix=/usr/local --user) runhaskell Setup.lhs build runhaskell Setup.lhs install
A lot of projects were initiated that use the Haskore framework or something in the spirit of Haskore. This page may help to keep an overview of all projects. All maintainers of Haskore related projects are encouraged to add their project here and keep the references up to date.
