2006-03-06 * Regularise help text a bit.Eelco Dolstra1-1/+1
2005-12-24 * Documentation fixes.Eelco Dolstra1-2/+2
2005-10-06 * New query option: `--compare-versions' or `-c' to compare installedEelco Dolstra1-2/+4
versions to available versions, or vice versa. For example, the following compares installed versions to available versions: $ nix-env -qc autoconf-2.59 = 2.59 automake-1.9.4 < 1.9.6 f-spot-0.0.10 - ? firefox-1.0.4 < 1.0.7 ... I.e., there are newer versions available (in the current default Nix expression) for Automake and Firefox, but not for Autoconf, and F-Spot is missing altogether. Conversely, the available versions can be compared to the installed versions: $ nix-env -qac autoconf-2.59 = 2.59 automake-1.9.6 > 1.9.4 bash-3.0 - ? firefox-1.0.7 > 1.0.4 ... Note that bash is available but no version of it is installed. If multiple versions are available for comparison, then the highest is used. E.g., if Subversion 1.2.0 is installed, and Subversion 1.1.4 and 1.2.3 are available, then `nix-env -qc' will print `< 1.2.3', not `> 1.1.4'. If higher versions are available, the version column is printed in red (using ANSI escape codes).
2005-02-11 * Refactoring to support different installation sources in nix-env.Eelco Dolstra1-1/+2
* Set the references for the user environment manifest properly. * Don't copy the manifest (this was accidental). * Don't store derivation paths in the manifest (maybe this should be made optional). This cleans up the semantics of nix-env, which were weird. * Hash on the output paths of activated components, not on derivation paths. This is because we don't know the derivation path of already installed components anymore, and it allows the installation of components by store path (skipping Nix expressions entirely). * Query options `--out-path' and `--drv-path' to show the output and derivation paths of components, respectively (the latter replaces the `--expr' query).
2004-11-12 * Document --delete-generations and other nix-env options.Eelco Dolstra1-0/+4
2004-02-09 * In `--upgrade': added flags `--lt', `--leq', `--always' to specifyEelco Dolstra1-0/+10
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.
2004-02-08 * A command `--switch-generation' to switch to a specific generationEelco Dolstra1-0/+4
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.
2004-02-06 * Improvements to profiles. Generations are now per-profile, e.g.,Eelco Dolstra1-2/+2
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'.
2004-02-02 * Sort `nix-env -q' output by derivation name.Eelco Dolstra1-1/+1
* `--version' flag for all commands. * Manual updates.
2004-01-05 * Implemented Eelco V.'s `nix-env -I' command to specify the defaultEelco Dolstra1-4/+6
path of the Nix expression to be used with the import, upgrade, and query commands. For instance, $ nix-env -I ~/nixpkgs/pkgs/system/i686-linux.nix $ nix-env --query --available [aka -qa] sylpheed-0.9.7 bison-1.875 pango-1.2.5 subversion-0.35.1 ... $ nix-env -i sylpheed $ nix-env -u subversion There can be only one default at a time. * If the path to a Nix expression is a symlink, follow the symlink prior to resolving relative path references in the expression.
2004-01-05 * Implemented Eelco V.'s `-p' command to switch profiles. It switchesEelco Dolstra1-0/+2
the symlink ~/.nix-userenv to the given argument (which defaults to .../links/current). /etc/profile.d/nix-profile creates this symlink if it doesn't exist yet. Example use: $ nix-env -l my_profile -i foo.nix subversion quake $ nix-env -p my_profile I don't like the term "profile". Let's deprecate it :-)
2003-12-21 * Version numbers can be omitted in install/uninstall. E.g.,Eelco Dolstra1-2/+3
nix-env -i foo.nix subversion The version number part of a derivation name is defined as everything following the first dash not followed by a letter.
2003-12-21 * `-u' -> `-e'.Eelco Dolstra1-1/+2
* `--link' / `-l' flag to specify the switch symlink to use (by default, /nix/var/nix/links/current).
2003-12-01 * Help text for all (non-script) programs, so no more:Eelco Dolstra1-0/+31
$ nix-instantiate --help error: unknown flag `--help` Try `nix-instantiate --help' for more information. :-)
