2009-03-03* Allow the channel to declare a name for itself.Eelco Dolstra
2007-09-17* nix-env: allow ~/.nix-defexpr to be a directory. If it is, then theEelco Dolstra
Nix expressions in that directory are combined into an attribute set {file1 = import file1; file2 = import file2; ...}, i.e. each Nix expression is an attribute with the file name as the attribute name. Also recurses into directories. * nix-env: removed the "--import" (-I) option which set the ~/.nix-defexpr symlink. * nix-channel: don't use "nix-env --import", instead symlink ~/.nix-defexpr/channels. So finally nix-channel --update doesn't override any default Nix expressions but combines with them. This means that you can have (say) a local Nixpkgs SVN tree and use it as a default for nix-env: $ ln -s .../path-to-nixpkgs-tree ~/.nix-defexpr/nixpkgs_svn and be subscribed to channels (including Nixpkgs) at the same time. (If there is any ambiguity, the -A flag can be used to disambiguate, e.g. "nix-env -i -A nixpkgs_svn.pan".)
2007-05-16* New builtin function "isFunction". You're not supposed to use itEelco Dolstra
;-) * Channels: fix channels that are plain lists of derivations (like strategoxt-unstable) instead of functions (like nixpkgs-unstable). This fixes the error message "error: the left-hand side of the function call is neither a function nor a primop (built-in operation) but a list".
2007-05-01* Give unpacked channels more sensible names than 0, 1, ... They nowEelco Dolstra
get the basename of the channel URL (e.g., nixpkgs-unstable). The top-level Nix expression of the channel is now an attribute set, the attributes of which are the individual channels (e.g., {nixpkgs_unstable = ...; strategoxt_unstable = ...}). This makes attribute paths ("nix-env -qaA" and "nix-env -iA") more sensible, e.g., "nix-env -iA nixpkgs_unstable.subversion".
2006-05-12* Support for srcdir != builddir (NIX-41).Eelco Dolstra
2005-05-01* Be quiet when untarring a channel file.Eelco Dolstra
2005-03-15* Purify all corepkgs builders.Eelco Dolstra

2004-04-21* Channels. These allow you to stay current with an evolving set ofEelco Dolstra
Nix expressions. To subscribe to a channel (needs to be done only once): nix-channel --add \ http://catamaran.labs.cs.uu.nl/dist/nix/channels/nixpkgs-unstable This just adds the given URL to ~/.nix-channels (which can also be edited manually). To update from all channels: nix-channel --update This fetches the latest expressions and pulls cache manifests. The default Nix expression (~/.nix-defexpr) is made to point to the conjunction of the expressions downloaded from all channels. So to update all installed derivations in the current user environment: nix-channel --update nix-env --upgrade '*' If you are really courageous, you can put this in a cronjob or something. You can subscribe to multiple channels. It is not entirely clear what happens when there are name clashes between derivations from different channels. From nix-env/main.cc it appears that the one with the lowest (highest?) hash will be used, which is pretty meaningless.
