Re: [Haskell-cafe] Dual-licensing the package on Hackage

2013-07-30 Thread David Thomas
One question is how much of a discovery/indexing role Hackage plays. There can be a tremendous difference in ease of obtaining a commercial license, and a restriction for "things I can use in a proprietary project, once I pay enough" seems like a legitimate use case. It also has some bearing on e

Unless you want to provide multiple open source licenses, I don't see the point: Anybody that needs a commercial license (and has some money) will simply ask for such a commercial license when seeing that the code is available under GPL. Another reason it is pointless is that you will certainly n

Perhaps it would be best if .cabal allowed to have more than one license listed. Another solution would be to use custom field, for example: License: GPL x-Other-License: Commercial, see License-Commercial.txt All best, Krzysztof Skrzętnicki On Tue, Jul 30, 2013 at 11:44 AM, David Sorokin wrote

Well, if you are willing to grant me a GPL license when I download your package through Hackage, GPL is accurate. Again you are not providing me with another license. Obtaining a commercial license should be seeked through other means, perhaps by sending you an email. I don't think Hackage should

Thanks Thu, I agree with you. Just I don't know what to write in the license field of the .cabal file: GPL or OtherLicense. The both choices seem correct to me and misleading at the same time. Cheers, David 30.07.2013, в 12:53, Vo Minh Thu написал(а): > 2013/7/30 David Sorokin : >> Hi, Cafe!
