2017-07-20nix-shell: Use bashInteractive from <nixpkgs>Eelco Dolstra
This adds about 0.1s to nix-shell runtime in the case where bashInteractive already exists. See discussion at https://github.com/NixOS/nixpkgs/issues/27493.
2017-07-20Add "nix search" commandEelco Dolstra

2017-04-19getDerivations(): Filter out packages with bad derivation namesEelco Dolstra
In particular, this disallows attribute names containing dots or starting with dots. Hydra already disallowed these. This affects the following packages in Nixpkgs master: 2048-in-terminal 2bwm 389-ds-base 90secondportraits lispPackages.3bmd lispPackages.hu.dwim.asdf lispPackages.hu.dwim.def Closes #1342.
2017-01-26Bindings: Add a method for iterating in lexicographically sorted orderEelco Dolstra
2016-11-26Revert "Get rid of unicode quotes (#1140)"Eelco Dolstra
This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...

2016-08-29forceBool(): Show position infoEelco Dolstra
2016-04-25Improved logging abstractionEelco Dolstra
This also gets rid of --log-type, since the nested log type isn't useful in a multi-threaded situation, and nobody cares about the "pretty" log type.
2016-02-23nix-env: respect meta.outputsToInstallVladimír Čunát

2016-01-05First hit at providing support for floats in the language.Christian Theune
2015-07-23Optimize small listsEelco Dolstra
The value pointers of lists with 1 or 2 elements are now stored in the list value itself. In particular, this makes the "concatMap (x: if cond then [(f x)] else [])" idiom cheaper.

2014-09-19Store Attrs inside BindingsEelco Dolstra
This prevents a double allocation per attribute set.

2013-11-19Generalise meta attributesEelco Dolstra
2013-10-24Rename "attribute sets" to "sets"Eelco Dolstra
We don't have any other kind of sets so calling them attribute sets is unnecessarily verbose.
2012-11-28nix-env -q --out-path: Support multiple outputsEelco Dolstra
We now print all output paths of a package, e.g. openssl-1.0.0i bin=/nix/store/gq2mvh0wb9l90djvsagln3aqywqmr6vl-openssl-1.0.0i-bin;man=/nix/store/7zwf5r5hsdarl3n86dasvb4chm2xzw9n-openssl-1.0.0i-man;/nix/store/cj7xvk7fjp9q887359j75pw3pzjfmqf1-openssl-1.0.0i or (in XML mode) <item attrPath="openssl" name="openssl-1.0.0i" system="x86_64-linux"> <output name="bin" path="/nix/store/gq2mvh0wb9l90djvsagln3aqywqmr6vl-openssl-1.0.0i-bin" /> <output name="man" path="/nix/store/7zwf5r5hsdarl3n86dasvb4chm2xzw9n-openssl-1.0.0i-man" /> <output name="out" path="/nix/store/cj7xvk7fjp9q887359j75pw3pzjfmqf1-openssl-1.0.0i" /> </item>
2012-11-26nix-instantiate: Fix read-only evaluationEelco Dolstra
2012-10-04getDerivation(): Don't always quietly ignore assertion failureEelco Dolstra
Ignoring assertion failures makes some sense for nix-env -qa, but not for nix-instantiate/nix-build or hydra-eval-jobs.
2012-02-04* Inline some functions and get rid of the indirection throughEelco Dolstra
EvalState::eval(). This gives a 12% speedup on ‘nix-instantiate /etc/nixos/nixos/ -A system --readonly-mode’ (from 1.01s to 0.89s).
2010-10-24* Keep attribute sets in sorted order to speed up attribute lookups.Eelco Dolstra
* Simplify the representation of attributes in the AST. * Change the behaviour of listToAttrs() in case of duplicate names.
2010-10-24* Store attribute sets as a vector instead of a map (i.e. a red-blackEelco Dolstra
tree). This saves a lot of memory. The vector should be sorted so that names can be looked up using binary search, but this is not the case yet. (Surprisingly, looking up attributes using linear search doesn't have a big impact on performance.) Memory consumption for $ nix-instantiate /etc/nixos/nixos/tests -A bittorrent.test --readonly-mode on x86_64-linux with GC enabled is now 185 MiB (compared to 946 MiB on the trunk).
2010-10-22* Store Value nodes outside of attribute sets. I.e., Attr now storesEelco Dolstra
a pointer to a Value, rather than the Value directly. This improves the effectiveness of garbage collection a lot: if the Value is stored inside the set directly, then any live pointer to the Value causes all other attributes in the set to be live as well.
2010-05-07* Keep track of the source positions of attributes.Eelco Dolstra
2010-04-21* Store user environment manifests as a Nix expression inEelco Dolstra
$out/manifest.nix rather than as an ATerm. (Hm, I thought I committed this two days ago...)
2010-04-19* Added parsing of manifests in ATerm format.Eelco Dolstra
2010-04-16* In an nested `with' where the inner with is a variable (`with ...;Eelco Dolstra
with someVar; ...'), the contents of the variable would be clobbered. (The attributes in the outer `with' were added to the variable.)
2010-04-15* Store lists as lists of pointers to values rather than as lists ofEelco Dolstra
values. This improves sharing and gives another speed up. Evaluation of the NixOS system attribute is now almost 7 times faster than the old evaluator.
2010-04-13* Use a symbol table to represent identifiers and attribute namesEelco Dolstra
efficiently. The symbol table ensures that there is only one copy of each symbol, thus allowing symbols to be compared efficiently using a pointer equality test.
2010-04-12* Don't use ATerms for the abstract syntax trees anymore. NotEelco Dolstra
finished yet.
2010-04-07* Update autoCallFunction() and findAlongAttrPath().Eelco Dolstra
2010-04-07* Implemented the primops necessary for generating the NixOS manual.Eelco Dolstra
2010-04-01* Improve sharing.Eelco Dolstra
2010-03-31* Get nix-env to compile.Eelco Dolstra
2010-03-31* Implemented derivations.Eelco Dolstra
2010-03-29* Started integrating the new evaluator.Eelco Dolstra
2009-06-30* Support integers and lists of strings in meta fields. This isEelco Dolstra
useful for fields like meta.maintainers, meta.priority (which can be a proper integer now) and even meta.license (if there are multiple licenses).
2008-08-25* Evaluate attributes in sorted order for better determinism.Eelco Dolstra
2008-08-25* Minor simplification.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".)
2007-05-01* 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".
2007-05-01* nix-env -i: instead of breaking package ties by version, break themEelco Dolstra
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' derivationEelco Dolstra
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
