Eelco Dolstra 383f9bb0f1 * Use ATerms for Nix descriptors. 2003-04-01 14:00:47 +00:00
Eelco Dolstra ced20f187e * Nix descriptor for Subversion. 2003-03-31 14:28:15 +00:00
Eelco Dolstra 31f177ef0a * Check for collissions. 2003-03-28 16:27:23 +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 0f40a560ca * Added a script nix-activate which builds a list of "activated"
packages (i.e., the packages that should appear in the user's $PATH,
  and so on).  Based on this list, the script nix-populate creates a
  hierarchy of symlinks to the relevant files in those packages (e.g.,
  for pkg/bin and pkg/lib).  

  A nice property of nix-populate is that on each run it creates a
  *new* tree, rather than updating the old one.  It then atomically
  switches over to the new tree.  This allows atomic upgrades or
  rollbacks on the set of activated packages.

Eelco Dolstra 3f1a1457e9 * Integrate hash into instantiated descriptor file names.
* Use MD5::Digest.

Eelco Dolstra 73c53935d0 * For efficiency: md5 integrated into nix.
* Command `nix ensure' which is like `nix getpkg' except that if the
  has refers to a run action it will just ensure that the imports are
  there.
* Command `nix closure' to print out the closure of the set of
  descriptors under the import relation, starting at a set of roots.
  This can be used for garbage collection (e.g., given a list of
  `activated' packages, we can delete all packages not reachable from
  those).
* Command `nix graph' to print out a Dot graph of the dependency
  graph.
* `nix-addroot' adds a root for the (unimplemented) garbage collector.

Eelco Dolstra eeab86e0ac * Typo fix. 2003-03-24 16:43:52 +00:00
Eelco Dolstra 2dc84e5569 * Descriptors now have a "system" field specifying the platform that
the build or run action should be perfomed on.  This ensures that
  descriptors have different hashes on different platforms.

Eelco Dolstra 9d2f128252 * Refactoring. 2003-03-24 11:50:20 +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.

Eelco Dolstra 20d165c344 * A command to run programs in Nix packages, that is, to execute a run
action.  Run actions are described by uniquely hashed descriptors,
  just like build actions.  Therefore run actions can have
  dependencies, but these need not be the same as the build time
  dependencies (e.g., at runtime we can link against a different
  version of a dynamic library).  Example:

    nix run 31d6bf4c171282367065e0deecd7c579

  will run the Pan 0.13.91 newsreader with gtkspell support.

Eelco Dolstra 800d8e950f * Added a command to list installed packages. 2003-03-21 15:58:40 +00:00
Eelco Dolstra 2e59698b78 * Added a command to verify the consistency of the database. 2003-03-21 15:53:35 +00:00
Eelco Dolstra fa51d6fcd9 * Forgot to commit this one. 2003-03-21 14:11:44 +00:00
Eelco Dolstra e582ee67cd * Fetch sources from the network. 2003-03-21 14:10:06 +00:00
Eelco Dolstra 88d257b17f * Renamed dist -> build. 2003-03-21 09:58:01 +00:00
Eelco Dolstra 4c43711810 * Descriptor templates for the Pan newsreader and all its
dependencies.
2003-03-20 22:25:01 +00:00
Eelco Dolstra cadc3852e4 * nix-instantiate now instantiantes the closure of the set of
descriptor templates under the import relation.  I.e., we can now
  say:

    nix-instantiate outdir foo.nix

  which will create descriptors for foo.nix and all imported packages
  in outdir/.

Eelco Dolstra f7a98e081d * Various updates. 2003-03-20 16:53:00 +00:00
Eelco Dolstra b3594e9eaf * A script to instantiate package descriptors from templates. 2003-03-20 16:52:30 +00:00
Eelco Dolstra 8999f923ea * Improved Nix. Resources (package descriptors and other source
files) are now referenced using their cryptographic hashes.  

  This ensures that if two package descriptors have the same contents,
  then they describe the same package.  This property is not as
  trivial as it sounds: generally import relations cause this property
  not to hold w.r.t. temporality.  But since imports also use hashes
  to reference other packages, equality follows by induction.

Eelco Dolstra 841fcbd047 * And a trunk to go along with that. 2003-03-12 13:32:24 +00:00
