Eelco Dolstra 0ef4b6d0f8 * 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.

Eelco Dolstra ced20f187e * Nix descriptor for Subversion. 2003-03-31 14:28:15 +00:00
Eelco Dolstra 278ea4097e * Don't fork in `nix run'. 2003-03-28 10:33:34 +00:00
Eelco Dolstra f915f77349 * Allow arguments to be passed to programs in `nix run'. 2003-03-28 09:53:22 +00:00
Eelco Dolstra 8d682ba551 * A descriptor for running the Pan newsreader. 
* Added descriptors for gtkspell and its support package pspell.
  Gtkspell is an optional dependency of Pan, so we should add the
  ability to nix-instantiate to instantiate variants of a package
  based on a selection of features.
