Eelco Dolstra f8ac8d1ec8 * Began adding build farm docs. 2004-10-29 15:26:26 +00:00
Eelco Dolstra 37d7abd694 * New language feature: with expressions.
The expression `with E1; E2' evaluates to E2 with all bindings in
  the attribute set E1 substituted.  E.g.,

    with {x = 123;}; x

  evaluates to 123.  That is, the attribute set E1 is in scope in E2.

  This is particularly useful when importing files containing lots
  definitions.  E.g., instead of

    let {
      inherit (import ./foo.nix) a b c d e f;

      body = ... a ... f ...;
    }

  we can now say

    with import ./foo.nix;

    ... a ... f ...

  I.e., we don't have to say what variables should be brought into scope.

Eelco Dolstra 2cd590d96c * Instead of — use the actual Unicode character. By the way, to
edit the manual, you should have something like

    (modify-coding-system-alist 'file "\\.xml\\>" 'utf-8)

  in your ~/.emacs.

Eelco Dolstra 692204e0c5 * Rewrite of package management stuff. 2004-10-14 16:43:09 +00:00
Eelco Dolstra febd8bed1b * Split overview chapter into a chapter on package management and a
chapter on writing Nix expressions.
2004-10-14 11:55:12 +00:00
Eelco Dolstra 98c69e5172 * Unindent. 2004-10-14 11:54:41 +00:00
Eelco Dolstra 371c57d8a7 * Updated the quick start section. Use channels instead of
downloading Nix expressions and calling nix-pull.  This is so
  user-friendly that even a Mac user can do it! :-)
2004-10-13 15:35:47 +00:00
Eelco Dolstra 2b20701f78 * Better introduction.
* Set notes in a different color than warnings.
2004-10-13 15:08:35 +00:00
Eelco Dolstra 5396304c73 * Use setre[ug]id() instead of setres[ug]id(), since the former is
more common than the latter (which exists only on Linux and
  FreeBSD).  We don't really care about dropping the saved IDs since
  there apparently is no way to quiry them in any case, so it can't
  influence the build (unlike the effective IDs which are checked by
  Perl for instance).
2004-09-09 15:55:31 +00:00
Eelco Dolstra eb233e728f * `--min-age' flag in nix-store and nix-collect-garbage to only delete
unreachable paths that haven't been used for N hours.  For instance,
  `nix-collect-garbage --min-age 168' only deletes paths that haven't
  been accessed in the last week.

  This is useful for instance in the build farm where many derivations
  can be shared between consecutive builds, and we wouldn't want a
  garbage collect to throw them all away.  We could of course register
  them as roots, but then we'd to unregister them at some point, which
  would be a pain to manage.  The `--min-age' flag gives us a sort of
  MRU caching scheme.

  BUG: this really shouldn't be in gc.cc since that violates
  mechanism/policy separation.
2004-08-25 16:54:08 +00:00
Eelco Dolstra fdec72c6cc * `nix-collect-garbage' now actually performs a garbage collection, it
doesn't just print the set of paths that should be deleted.  So
  there is no more need to pipe the result into `nix-store --delete'
  (which doesn't even exist anymore).
2004-08-25 15:39:13 +00:00
Eelco Dolstra 1eddee59f2 * The default verbosity level of all Nix commands is now lvlInfo.
* Builder output is written to standard error by default.
  * The option `-B' is gone.
  * The option `-Q' suppresses builder output.

The result of this is that most Nix invocations shouldn't need any
flags w.r.t. logging.
2004-08-18 12:19:06 +00:00
Eelco Dolstra 151e61fa5a * By default, `nix-env -i' now deletes previously installed
derivations with names matching the derivations being installed.
  The option `--preserve-installed / -P' overrides this behaviour.
2004-06-28 14:40:26 +00:00
Eelco Dolstra 24286e15c9 * `nix-env -u' now allows a specific version to be specified when
upgrading.

  This fixes a bug reported by Martin:

    $ nix-env -i foo-1.0
    $ nix-env -u foo-1.0
    upgrading foo-1.0 to foo-1.1
2004-06-28 13:37:05 +00:00
Eelco Dolstra 91dc023665 * Added a switch `--fallback'. From the manual:
Whenever Nix attempts to realise a derivation for which a closure is
  already known, but this closure cannot be realised, fall back on
  normalising the derivation.

  The most common scenario in which this is useful is when we have
  registered substitutes in order to perform binary distribution from,
  say, a network repository.  If the repository is down, the
  realisation of the derivation will fail.  When this option is
  specified, Nix will build the derivation instead.  Thus, binary
  installation falls back on a source installation.  This option is
  not the default since it is generally not desirable for a transient
  failure in obtaining the substitutes to lead to a full build from
  source (with the related consumption of resources).
2004-06-28 10:42:57 +00:00
Eelco Dolstra b113edeab7 * A flag `--keep-going / -k' to keep building goals if one fails, as
much as possible.  (This is similar to GNU Make's `-k' flag.)

* Refactoring to implement this: previously we just bombed out when
  a build failed, but now we have to clean up.  In particular this
  means that goals must be freed quickly --- they shouldn't hang
  around until the worker exits.  So the worker now maintains weak
  pointers in order not to prevent garbage collection.

* Documented the `-k' and `-j' flags.
2004-06-25 15:36:09 +00:00
Eelco Dolstra bcce9c1ff5 * Only add `-preRELEASE' to the version if STABLE != 1.
* Documented release procedures.
2004-04-26 09:52:06 +00:00

Eelco Dolstra b0c9baf1b5 * EBNF grammar for the Nix expression language. 2004-04-08 13:31:57 +00:00
Eelco Dolstra 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.
2004-02-10 16:14:47 +00:00
Eelco Dolstra 0616b7feea * Documented the most important nix-env flags. 2004-02-10 11:51:16 +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'.
