Question: Confirmation of intent of GPL license #12

Open funatsufumiya opened 9 months ago

funatsufumiya commented 9 months ago

@danomatika First of all, I am truly impressed with loaf, and thank you for developing such a great tool.

And I would like to contribute to the development of ofxLua and related additional add-ons, and therefore, I would like to reaffirm the intent of the license.

As a guess, I felt that the licensing structure is similar to Processing and processing.core, but there are some subtle differences, which resulted in significant differences.

If loaf had the ability to create stand-alone executables similar to the Processing IDE, the situation would be different. At this point, creating a program that links only to ofxLua requires manual creation, which is not much of a task for Lua scripts only, but if custom C++ add-ons are included, the licensing of the add-ons themselves and the licensing of the distribution software become somewhat tricky.

I myself of course would like to contribute to open software as much as possible, I would really appreciate it if I could confirm the intent of the license and the design policy.

If my guess is correct, I feel that a license "with an exception", such as OpenJDK's GPLv2 with the Classpath Exception, would be most appropriate for loaf at this time, rather than pure GPL.

( I think this is not the case if we only write Lua scripts, but it is still a barrier when redistributing the application. )

I am up for options on this and changing/re-licensing. I generally choose 1. BSD for libraries / iOS-stuff or 2. GPL for tools / environments. I think you are right in that loaf falls somewhere between the two. Maybe it's worth looking at similar environments like LÖVE which loaf is partially modeled after?

@danomatika I am very glad to hear your thoughts. I agree with you on the classification of licenses. However, as I don't currently have the optimal solution, I will do some more research myself.

As an alternative to changing the license, a stand-alone executable output function like the Processing IDE might be a solution, but the build mechanism of OpenFrameworks is complicated, so I'm also considering what kind of solution might be possible.

There is a script to create stand alone macOS apps. Similar scripts could be created for other platforms.enohp ym morf tnes-----------Dan Wilcoxdanomatika.comrobotcowboy.comOn Feb 18, 2024, at 12:22 PM, Fumiya Funatsu @.***> wrote: @danomatika I am very glad to hear your thoughts.

@danomatika Thank you. With forking it, I'm going to try something to make it possible to automatically output an executable with another add-on without linking directly to loaf binary itself.

( If I find something looks good, I will PR it. )
