Re: Am I Allowed to Make a New Compiler/Language using Perl?

This, I think, is the licence for Perl itself. But I think that what you are describing is whether the licence for the language restricts in any way what you can do using the language. The answer to that is an absolute "No". Your code, your rules. Frequently, people say that their code is under the same terms as Perl itself. But no creator of tools has any power over the artefacts created using those tools. Bill Gates doesn't get any royalties from books written in MessWord, and you can bet on it that he'd try if he thought he could.

I'm guessing that your concern is down to the campaign against the GPL that Redmond has been waging for years. They have been claiming that by using GPL software, you lose rights to your own creations. This is nothing but FUD. Terry Pratchett has invented the term "Deja Moo", meaning "I have heard this bull before". It applies here. Whatever Redmond want you to fear, you have absolute rights over your own creations. Even if you didn't, Tim Toady's pronouncements on the link I started with make it clear that, using Perl, you would.

Actually not always. http://www.readwriteweb.com/archives/does_google_have_rights_to_all.php and http://en.wikipedia.org/wiki/Adobe_Photoshop_Express#Terms_of_Use You'll often find license agreements which state that the output of the program, your image, is owned by the maker of the software since your image is a derivative of the software and therefore the copyright is owned by the maker. I dont think this has ever been enforced in any court, and the bad PR would ban the maker's software from every corporation in the world, so no maker dares enforce it.	[reply]

Well, you don't find such clauses in open source licences Perl 6 - second systems done right	[reply]

I think the GPL v3 comes close, or at least forces restrictions on the (distribution of) the output generated by a GPL v3 program. But I have solved this problem for me personally a long time before the GPL v3, so I haven't investigated whether that is really the case for things like a compiler. It seems to be the case for things like web application servers, where accessing the application over the web is basically identical to distribution of the application server binary.	[reply]

Well, IANAL, but I can't imagine that sort of clause standing up in court in the UK. Despite what makes a good story for the newspapers, UK judges tend to apply common sense, especially in common law, which covers most of contract. They would put such clauses on a par with a saw manufacturer claiming rights over chairs. There is some statute law, but that tends to protect consumers, for example http://www.oft.gov.uk/about-the-oft/legal-powers/legal/unfair-terms/. But other countries will differ.
