2007-05-01	* nix-env -i: instead of breaking package ties by version, break them	Eelco Dolstra	1	-0/+1
	by priority and version install. That is, if there are multiple packages with the same name, then pick the package with the highest priority, and only use the version if there are multiple packages with the same priority. This makes it possible to mark specific versions/variant in Nixpkgs more or less desirable than others. A typical example would be a beta version of some package (e.g., "gcc-4.2.0rc1") which should not be installed even though it is the highest version, except when it is explicitly selected (e.g., "nix-env -i gcc-4.2.0rc1"). * Idem for nix-env -u, only the semantics are a bit trickier since we also need to take into account the priority of the currently installed package (we never upgrade to a lower priority, unless --always is given).
2007-02-02	* nix-env now maintains meta info (from the `meta' derivation	Eelco Dolstra	1	-0/+5
	attribute) about installed packages in user environments. Thus, an operation like `nix-env -q --description' shows useful information not only on available packages but also on installed packages. * nix-env now passes the entire manifest as an argument to the Nix expression of the user environment builder (not just a list of paths), so that in particular the user environment builder has access to the meta attributes. * New operation `--set-flag' in nix-env to change meta info of installed packages. This will be useful to pass per-package policies to the user environment builder (e.g., how to resolve collision or whether to disable a package (NIX-80)) or upgrade policies in nix-env (e.g., that a package should be "masked", that is, left untouched by upgrade actions). Example: $ nix-env --set-flag enabled false ghc-6.4
2006-09-04	* Use a proper namespace.	Eelco Dolstra	1	-2/+8
	* Optimise header file usage a bit. * Compile the parser as C++.
2006-07-28	* `nix-instantiate ... --arg NAME VALUE': allow arguments to be passed	Eelco Dolstra	1	-1/+1
	to functions from the command line. * nix-build: started removing backticks.
2006-07-26	* Refactoring: get the selection path stuff out of getDerivations()	Eelco Dolstra	1	-2/+2
	and put it into a separate function findAlongAttrPath().
2006-07-25	* Applied rbroek's patch from the branch at	Eelco Dolstra	1	-0/+1
	https://svn.cs.uu.nl:12443/repos/trace/buildfarm-control/trunk/ext/nix/, with some modifications. This allows `nix-env -qa' to show the attribute path that can be used to unambiguously install a package using `nix-env -i -A'. Example: $ nix-env -f top-level/all-packages.nix -qaA subversion xorg-server subversionWithJava subversion-1.2.3 subversion subversion-1.3.2 subversion14 subversion-1.4.0pre-rc1 xorg.xorgserver xorg-server-1.1.0
2006-05-02	* Huge reduction in memory use (2/3 or so on large nix-env -qas	Eelco Dolstra	1	-1/+3
	operations): share ATermMaps between DrvInfos.
2006-03-10	* `nix-env -qa --description' shows human-readable descriptions of	Eelco Dolstra	1	-18/+6
	packages (provided that they have a `meta.description' attribute). E.g., $ ./src/nix-env/nix-env -qa --description gcc gcc-4.0.2 GNU Compiler Collection, 4.0.x (cross-compiler for sparc-linux) gcc-4.0.2 GNU Compiler Collection, 4.0.x (cross-compiler for mips-linux) gcc-4.0.2 GNU Compiler Collection, 4.0.x (cross-compiler for arm-linux) gcc-4.0.2 GNU Compiler Collection, 4.0.x
2006-02-10	* In nix-instantiate, allow us to specify a "path" to the	Eelco Dolstra	1	-1/+2
	derivation(s) we're interested, e.g., $ nix-instantiate ./all-packages.nix --attr xlibs.libX11 List elements can also be selected: $ nix-instantiate ./build-for-release.nix --attr 0.subversion This allows a non-ambiguous specification of a derivation. Of course, this should also be added to nix-env and nix-build.
2006-02-08	* Refactoring: move derivation evaluation to libexpr.	Eelco Dolstra	1	-0/+64
