I'm no compiler writer but as a layperson I'd guess for that you'd at least need a program that could determine if two constructs are equivalent, the Haskell and Python list comprehension example from 2 emails ago. The only way I can think to do that is to parse some source in language X and see if the AST generated is the same as language Y. As far as something fully automated my intuition tells me that you'd need a single program that could act as a compiler and/or interpreter for all the languages you're trying to test. This is the only way, for example, to automatically determine that variable scoping works the same in Javascript and Scheme. -deech On Thu, Nov 4, 2010 at 10:03 AM, Dupont Corentin <corentin.dupont@gmail.com>wrote:
Hello, reading this thread a question came to me: Is there a way of automatically deriving programming languages ascendancy?
Like biologist can determine the distance between two genotypes, and determine a hierarchy between species from that.
Are you aware of researchs made in the field?
On the net I found interesting graphs but no comments on the methodology. http://www.levenez.com/lang/ http://rigaux.org/language-study/diagram.html
Cheers, Corentin
