I think your code is covered by whatever license you wish. An aggregate work, on the other hand, would need to be covered by the GPL, and all source code would have to be available under GPL terms. So if you distribute your code linked to or incorporating the GPL library, the whole must conform to the GPL license (source availability and redistributatbility, etc). Your contributions could still be licensed under a different license (e.g. BSD), as long as the licensing doesn't prevent somebody else to pick it up and relicense it under GPL. At least, that's how I understand things. -k -- If I haven't seen further, it is by standing in the footprints of giants ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

I wonder how APIs are covered. If your code use an API implemented by Pandoc (GPL) and also by another library licensed under, say, BSD3. Why should your code be licensed under GPL ? The only difference would be a build-depends in the .cabal. Has anyone an idea about this ?

Not quite true: it means that any code your BSD3 library gets used in has to have a GPL-compatible license: http://www.fsf.org/licensing/licenses/gpl-faq.html#IfLibraryIsGPL (this is the approach I've used for Graphalyze since I use Pandoc as a default library for document generation; later on I'm planning on re-doing the document part in which case it will _have_ to use Pandoc and thus I'll re-license the library). -- Ivan Lazar Miljenovic ivan.miljeno...@gmail.com IvanMiljenovic.wordpress.com ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

As has been discussed a few times before on this list, using LGPL for Haskell modules has its own set of problems when using GHC, due to the current state of linking in that compiler. From what I've read we're on a path to salvation with 6.12, but we're still not at the destination. /M -- Magnus Therning(OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus＠therning．org http://therning.org/magnus identi.ca|twitter: magthe ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

The main licence of darcs is GPL, but I've licensed all my contributions to it as BSD3. My view of this is that while darcs as a whole is obviously still GPL, any of my contributions that can be extracted independently can be used in other projects under BSD3. I'd say that with hakyll, the library itself can be under BSD3 but any executable you produce from it at the moment will necessarily be GPL. Not sure if there's any good way to communicate this fact in the metadata, though.

If Pandoc is LGPL, then I think that means we are dealing with an entirely different situation, one in which the library user can choose whatever license he or she likes for his or her own code as long as any modifications to the LGPL'd library itself are released under the LGPL.

The 3 clause BSD license is officially a GPL compatible license. See: http://www.gnu.org/licenses/license-list.html#GPLCompatibleLicenses It is within the terms of the GPL to link GPL code to a bunch of BSD3 code as long as you abide by both the GPL and the BSD3 license.

Most chunks of code can't switch license because they have dozens of contributions from dozens of people many of whom they no longer have contact with.

Hello all, Hakyll is a simple static site generator library, mostly aimed at blogs. It supports markdown, tex and html templates. It is inspired by the ruby Jekyll program. It has a very small codebase because it makes extensive use of the excellent pandoc and Text.Template libraries.
