* Cleaned up the semantics of Fix expressions. * Conditionals and variables in Fix expressions. This allows, e.g., Descr( [ Bind("pkgId", "subversion-0.21.0") , Bind("httpsClient", Bool(True)) , Bind("httpServer", Bool(True)) , Bind("ssl", If(Var("httpsClient"), Fix("./openssl-0.9.7b.fix"), "")) , Bind("httpd", If(Var("httpServer"), Fix("./httpd-2.0.45.fix"), "")) ... ]) which introduces domain feature variables httpsClient and httpServer (i.e., whether Subversion is built with https client and webdav server support); the values of the variables influences package dependencies and the build scripts. The next step is to allow that packages can express constraints on each other. E.g., StrategoXT is dependent on an ATerm library with the "gcc" variant enabled. In fact, this may cause several Nix instantiations to be created from a single Fix descriptor. If possible, Fix should try to find the least set of instantiations that obeys the constraints. 2003-04-25 18:33:50 +03:00			`Descr(`
