2007-05-01	* Give unpacked channels more sensible names than 0, 1, ... They now	Eelco Dolstra	1	-3/+12
	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".
2007-05-01	* nix-env -i: instead of breaking package ties by version, break them	Eelco Dolstra	1	-0/+9
	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/+10
	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
2007-01-13	* Cleanup.	Eelco Dolstra	1	-2/+2

2006-10-17	* Backwards compatibility hack for user environments made by Nix <= 0.10.	Eelco Dolstra	1	-0/+7

2006-10-16	* Big cleanup of the semantics of paths, strings, contexts, string	Eelco Dolstra	1	-8/+12
	concatenation and string coercion. This was a big mess (see e.g. NIX-67). Contexts are now folded into strings, so that they don't cause evaluation errors when they're not expected. The semantics of paths has been clarified (see nixexpr-ast.def). toString() and coerceToString() have been merged. Semantic change: paths are now copied to the store when they're in a concatenation (and in most other situations - that's the formalisation of the meaning of a path). So "foo " + ./bla evaluates to "foo /nix/store/hash...-bla", not "foo /path/to/current-dir/bla". This prevents accidental impurities, and is more consistent with the treatment of derivation outputs, e.g., `"foo " + bla' where `bla' is a derivation. (Here `bla' would be replaced by the output path of `bla'.)
2006-09-04	* Use a proper namespace.	Eelco Dolstra	1	-1/+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	-6/+7
	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	-98/+33
	and put it into a separate function findAlongAttrPath().
2006-07-25	* `nix-instantiate --print-args' prints out the arguments of a	Eelco Dolstra	1	-3/+3
	top-level function.
2006-07-25	* Applied rbroek's patch from the branch at	Eelco Dolstra	1	-15/+29
	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
2006-07-24	* Refactoring to support domain checks.	Eelco Dolstra	1	-4/+3

2006-07-19	* Better error messages (especially wrt types).	Eelco Dolstra	1	-4/+4

2006-05-30	* Don't use badTerm, it gives awful error messages.	Eelco Dolstra	1	-1/+2

2006-05-04	* Use the new ATermMap.	Eelco Dolstra	1	-21/+21

2006-05-02	* Huge reduction in memory use (2/3 or so on large nix-env -qas	Eelco Dolstra	1	-8/+8
	operations): share ATermMaps between DrvInfos.
2006-05-02	* Some preliminaries towards NIX-45.	Eelco Dolstra	1	-1/+1

2006-05-01	* Allow string concatenations involving derivations, e.g.,	Eelco Dolstra	1	-0/+4
	configureFlags = "--with-freetype2-library=" + freetype + "/lib";
2006-03-23	* In `nix-env', look for derivations inside attribute sets that have	Eelco Dolstra	1	-1/+15
	the `recurseForDerivations' attribute set to `true'.
2006-03-10	* `nix-env -qa --description' shows human-readable descriptions of	Eelco Dolstra	1	-0/+43
	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
2006-03-09	* Regression: semantics of the result of getDerivation() changed.	Eelco Dolstra	1	-2/+2

2006-03-08	* When obtaining derivations from Nix expressions, ignore all	Eelco Dolstra	1	-34/+50
	expressions that cause an assertion failure (like `assert system == "i686-linux"'). This allows all-packages.nix in Nixpkgs to be used on all platforms, even if some Nix expressions don't work on all platforms. Not sure if this is a good idea; it's a bit hacky. In particular, due to laziness some derivations might appear in `nix-env -qa' but disappear in `nix-env -qas' or `nix-env -i'. Commit 5000!
2006-02-10	* In nix-instantiate, allow us to specify a "path" to the	Eelco Dolstra	1	-26/+74
	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	* When querying all derivations, filter out syntactically equal derivations.	Eelco Dolstra	1	-12/+36

2006-02-08	* When evaluating, automatically call functions with default arguments.	Eelco Dolstra	1	-4/+23

2006-02-08	* Refactoring: move derivation evaluation to libexpr.	Eelco Dolstra	1	-0/+67
