Eelco Dolstra 79bb0008ec * `null' is a normal form. 2004-03-19 14:45:45 +00:00
Eelco Dolstra e6253b58cd * Escape codes to force line breaks to be ignored. 2004-03-18 21:32:15 +00:00
Eelco Dolstra 3f3c4cce5a * Added an extra escape code to signal "unimportant" messages. If a tree only has
unimportant messages, it is collapsed by the default.
* Also added an optional integer argument to the escape code for opening a nesting 
  level to indicate lack of importance.  If set, the tree is collapsed by default.
2004-03-18 21:04:14 +00:00
Eelco Dolstra 84c617966b * Collapsable trees. 2004-03-18 18:26:22 +00:00
Eelco Dolstra c2fc2c13c9 * Use unordered lists, which is more sensible semantically for
representing tree structures.
2004-03-18 14:58:16 +00:00
Eelco Dolstra a784fd5792 * Don't use tables. Konqueror likes this much better. 2004-03-18 13:04:05 +00:00
Eelco Dolstra 8ce3dd4887 * Display the popup directly over the abbreviation. 2004-03-17 16:55:53 +00:00
Eelco Dolstra 8330c8202a * A simpler way of implementing the store reference popups, thanks to
Martin and CSS guru Martijn Vermaat.
2004-03-17 16:52:48 +00:00
Eelco Dolstra b5539e7a30 * Store paths are now abbreviated in the generated HTML file.
Hovering over the abbreviated path will reveal the full path.  This
  probably only works in Mozilla.
2004-03-16 12:47:09 +00:00
Eelco Dolstra 9d2669d218 * Added a utility that can be used to produce nice HTML pages from Nix
build logs.  The program `log2xml' converts a Nix build log (read
  from standard input) into XML file that can then be converted to
  XHTML by the `log2html.xsl' stylesheet.  The CSS stylesheet
  `logfile.css' is necessary to make it look good.

  This is primarily useful if the log file has a *tree structure*,
  i.e., that sub-tasks such as the various phases of a build (unpack,
  configure, make, etc.) or recursive invocations of Make are
  represented as such.  While a log file is in principle an
  unstructured plain text file, builders can communicate this tree
  structure to `log2xml' by using escape sequences:

  - "\e[p" starts a new nesting level; the first line following the
    escape code is the header;

  - "\e[q" ends the current nesting level.

  The generic builder in nixpkgs (not yet committed) uses this.  It
  shouldn't be to hard to patch GNU Make to speak this protocol.

  Further improvements to the generated HTML pages are to allow
  collapsing/expanding of subtrees, and to abbreviate store paths (but
  to show the full path by hovering the mouse over it).

Eelco Dolstra beda10f5a2 * Make perl a dependency of Nix. 2004-03-15 15:23:53 +00:00
Eelco Dolstra 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.
2004-03-12 10:45:08 +00:00
Eelco Dolstra 7f0ed370da * Use $(storedir) instead of $(prefix)/store. 2004-02-20 11:32:30 +00:00
Eelco Dolstra dbf547645d * Resolve an ambiguity between ifs and attribute selection, e.g., `if
b then x else y.z'.
2004-02-19 13:11:12 +00:00
Eelco Dolstra 86b7efbdbe * Don't build ATerm library if we don't need to. 2004-02-16 16:48:06 +00:00
Eelco Dolstra 0dfdafdf6d * Allow linking against an external Berkeley DB / ATerm library. 2004-02-16 16:37:16 +00:00
Eelco Dolstra 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.
2004-02-16 15:23:19 +00:00
Eelco Dolstra fbc48a469c * Inherited attributes in recursive attribute sets are in scope of the
non-inherited attributes.
2004-02-16 09:18:35 +00:00
Eelco Dolstra 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.
2004-02-14 21:44:18 +00:00
Eelco Dolstra 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.
2004-02-13 10:43:31 +00:00
Eelco Dolstra 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.
2004-02-11 10:25:31 +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 6551b36790 * Print what generation we are switching to; honour --dry-run flag. 2004-02-10 13:42:58 +00:00
Eelco Dolstra 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.
2004-02-09 11:59:39 +00:00
Eelco Dolstra 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.
2004-02-08 14:07:43 +00:00
Eelco Dolstra b8675aee54 * In `--list-generations', show what the current generation is. 2004-02-06 16:16:55 +00:00
Eelco Dolstra 73ab2ed4fd * A command `--list-generations' to show all generations for a
profile.
2004-02-06 16:03:27 +00:00
Eelco Dolstra 7c0fa4474f * More refactoring. 2004-02-06 14:57:10 +00:00
Eelco Dolstra 7abf9911d9 * Refactoring. 2004-02-06 14:49:41 +00:00
Eelco Dolstra 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'.
2004-02-06 10:30:20 +00:00
Eelco Dolstra 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.
2004-02-04 17:23:26 +00:00
Eelco Dolstra 9d25466b34 * An attribute set update operator (//). E.g.,
{x=1; y=2; z=3;} // {y=4;}  =>  {x=1; y=4; z=3;}
2004-02-04 16:49:51 +00:00
Eelco Dolstra 6d46e647ba * Fixed the old envpkgs filename. 2004-02-04 16:20:51 +00:00
Eelco Dolstra 9b44480612 * Use a map to lookup primops.
* Various performance improvements in the evaluator.
* Do not link against unused (and missing!) libraries (-lsglr, etc.).
2004-02-04 16:03:29 +00:00
Eelco Dolstra 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}'.
2004-02-02 21:39:33 +00:00
Eelco Dolstra d9f30fe7c7 * Sort `nix-env -q' output by derivation name.
* `--version' flag for all commands.
* Manual updates.
2004-02-02 10:51:54 +00:00
Eelco Dolstra 47c003cb59 * Doh! 2004-01-30 17:14:08 +00:00
Eelco Dolstra 619f20775d * Parser numbers again.
* Include missing files in distributions.
2004-01-30 17:06:03 +00:00
Eelco Dolstra 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.
2004-01-30 15:21:42 +00:00
Eelco Dolstra abd1878b26 * Optimised the SDF grammar. 2004-01-29 14:24:53 +00:00
Eelco Dolstra 3648d1c732 * Explicitly compute the release name. 2004-01-22 13:04:57 +00:00
Eelco Dolstra cdb50886f4 * Typos. 2004-01-22 09:35:35 +00:00
Eelco Dolstra 3c4bc7276a * Added a note about adding /nix/etc/profile.d/nix.sh to the profile. 2004-01-22 09:17:55 +00:00
Martin Bravenboer 4f72b408a5 Typos and url losser -> catamaran 2004-01-22 08:47:59 +00:00
Eelco Dolstra 840551ebdb * Extra bit S' in --query --status' output: show whether there are
any substitutes for the derivation.
