beda10f5a2 * Make perl a dependency of Nix. 2004-03-15 15:23:53 +00:00

a5619f1dff * Set the NIX_STORE and NIX_BUILD_TOP environment variables in
builders to point to the store and the temporary build directory,
  respectively.  Useful for purity checking.
* Also set TEMPDIR, TMPDIR, TEMP, and TEMP to NIX_BUILD_TOP to make
  sure that tools in the builder store temporary files in the right
  location.

dbf547645d * Resolve an ambiguity between ifs and attribute selection, e.g., `if
b then x else y.z'.

f34de12140 * Allow the location of the store to be specified (--with-store-dir).
* Do not create stuff in localstatedir when doing `make install'
  (since we may not have write access).  In general, installation of
  constant code/data should be separate from the initialisation of
  mutable state.

fbc48a469c * Inherited attributes in recursive attribute sets are in scope of the
non-inherited attributes.

76c0e85929 * The environment variable NIX_ROOT can now be set to execute Nix in a
chroot() environment.
* A operation `--validpath' to register path validity.  Useful for
  bootstrapping in a pure Nix environment.
* Safety checks: ensure that files involved in store operations are in
  the store.

6f5a5ea5ea * Regression fix: realise substitutes and detect cycles. 2004-02-13 10:45:09 +00:00
Eelco Dolstra
1ad9d11247 * Only include predecessors that are themselves being pushed.
Otherwise the substitute mechanism can break in subtle ways.

00fe1a506f * When creating a new generation, also make the normal form of the
derivation (i.e., the closure store expression) a root of the
  garbage collector.  This ensures that running `nix-collect-garbage
  --no-successors' is safe.

92e832348d * Lots of manual stuff. Reference pages for most Nix commands.
* nix-pull now requires the full url to the manifest, i.e.,
  `/MANIFEST/' is no longer automatically appended.
* nix-prefetch-url works again.

6551b36790 * Print what generation we are switching to; honour --dry-run flag. 2004-02-10 13:42:58 +00:00

0616b7feea * Documented the most important nix-env flags. 2004-02-10 11:51:16 +00:00
Eelco Dolstra
618aa69b01 * In --upgrade': added flags --lt', --leq', --always' to specify
whether we want to upgrade if the current version is less than the
  available version (default), when it is less or equal, or always.
  
* Added a flag `--dry-run' to show what would happen in `--install',
  `--uninstall', and `--upgrade', without actually performing the
  operation.

06a75a7e0c * A command `--switch-generation' to switch to a specific generation
of the current profile, e.g.,

    $ nix-env --list-generations
    ...
    39   2004-02-02 17:53:53
    40   2004-02-02 17:55:18
    41   2004-02-02 17:55:41
    42   2004-02-02 17:55:50   (current)

    $ nix-env --switch-generation 39

    $ ls -l /nix/var/nix/profiles/default
    ... default -> default-39-link

* Also a command `--rollback' which is just a convenience operation to
  rollback to the oldest generation younger than the current one.

  Note that generations properly form a tree.  E.g., if after
  switching to generation 39, we perform an installation action,
  a generation 43 is created which is a descendant of 39, not 42.  So
  a rollback from 43 ought to go back to 39.  This is not currently
  implemented; generations form a linear sequence.

73ab2ed4fd * A command `--list-generations' to show all generations for a

49bafe1faf * Use the profile pointed to by ~/.nix-profile if no --profile
argument is specified.
2004-02-06 10:59:06 +00:00
Eelco Dolstra
66e94d3275 * Improvements to profiles. Generations are now per-profile, e.g.,
default -> default-94-link
  default-82-link -> /nix/store/cc4480...
  default-83-link -> /nix/store/caeec8...
  ...
  default-94-link -> /nix/store/2896ca...
  experimental -> experimental-2-link
  experimental-1-link -> /nix/store/cc4480...
  experimental-2-link -> /nix/store/a3148f...

* `--profile' / `-p' -> `--switch-profile' / `-S'
* `--link' / `-l' -> `--profile' / `-p'
* The default profile is stored in $prefix/var/nix/profiles.
  $prefix/var/nix/links is gone.  Profiles can be stored anywhere.
* The current profile is now referenced from ~/.nix-profile, not
  ~/.nix-userenv.
* The roots to the garbage collector now have extension `.gcroot', not
  `.id'.

d445da7a7b * Extended the `inherit' syntax to optionally select attributes from
other attribute sets, rather than the current scope.  E.g.,
  
    {inherit (pkgs) gcc binutils;}

  is equivalent to

    {gcc = pkgs.gcc; binutils = pkgs.binutils;}

  I am not so happy about the syntax.

9d25466b34 * An attribute set update operator (//). E.g.,
{x=1; y=2; z=3;} // {y=4;}  =>  {x=1; y=4; z=3;}

9b44480612 * Use a map to lookup primops.
* Various performance improvements in the evaluator.
* Do not link against unused (and missing!) libraries (-lsglr, etc.).

c4f7ae4aa5 * Verify that all variables in a Nix expression are defined. 2004-02-03 14:45:34 +00:00
Eelco Dolstra
1c9c0a5a46 * Added syntactic sugar to the construction of attribute sets to
`inherit' variables from the surrounding lexical scope.

  E.g.,

    {stdenv, libfoo}: derivation {
      builder = ./bla;
      inherit stdenv libfoo;
      xyzzy = 1;
    }

  is equivalent to

    {stdenv, libfoo}: derivation {
      builder = ./bla;
      stdenv = stdenv;
      libfoo = libfoo;
      xyzzy = 1;
    }

  Note that for mutually recursive attribute set definitions (`rec
  {...}'), this also works, that is, `rec {inherit x;}' is equivalent
  to `let {fresh = x; body = rec {x = fresh;};}', *not*
  `rec {x = x}'.

c625718513 * Detect flex and bison; updated the manual. 2004-01-30 16:32:14 +00:00
Eelco Dolstra
c5baaafae6 * Replaced the SDF parser by a substantially faster Bison/Flex
parser (roughly 80x faster).

  The absolutely latest version of Bison (1.875c) is required for
  reentrant GLR support, as well as a recent version of Flex (say,
  2.5.31).  Note that most Unix distributions ship with the
  prehistoric Flex 2.5.4, which doesn't support reentrancy.
