2014-07-30	Rename nixPath to __nixPath	Eelco Dolstra	1	-2/+2
	The name ‘nixPath’ breaks existing code.
2014-07-09	Fix compilation error on some versions of GCC	Eelco Dolstra	1	-0/+1
	src/libexpr/primops.cc:42:8: error: looser throw specifier for 'virtual nix::InvalidPathError::~InvalidPathError()' src/libexpr/nixexpr.hh:12:1: error: overriding 'virtual nix::EvalError::~EvalError() noexcept (true)' http://hydra.nixos.org/build/12385750

	Fixes #294.
2014-06-24	Only add the importNative primop if the ↵	Shea Levy	1	-1/+2
	allow-arbitrary-code-during-evaluation option is true (default false)
2014-06-17	Add importNative primop	Shea Levy	1	-0/+42
	This can be used to import a dynamic shared object and return an arbitrary value, including new primops. This can be used both to test new primops without having to recompile nix every time, and to build specialized primops that probably don't belong upstream (e.g. a function that calls out to gpg to decrypt a nixops secret as-needed). The imported function should initialize the Value & as needed. A single import can define multiple values by creating an attrset or list, of course. An example initialization function might look like: extern "C" void initialize(nix::EvalState & state, nix::Value & v) { v.type = nix::tPrimOp; v.primOp = NEW nix::PrimOp(myFun, 1, state.symbols.create("myFun")); } Then `builtins.importNative ./example.so "initialize"` will evaluate to the primop defined in the myFun function.
2014-06-12	Drop ImportError and FindError	Eelco Dolstra	1	-4/+0
	We're not catching these anywhere.
2014-06-12	findFile: Realise the context of the path attributes	Shea Levy	1	-18/+44

2014-06-12	Share code between scopedImport and import	Shea Levy	1	-42/+44
	In addition to reducing duplication, this fixes both import from derivation and import of derivation for scopedImport
2014-06-10	== operator: Ignore string context	Eelco Dolstra	1	-1/+1
	There really is no case I can think of where taking the context into account is useful. Mostly it's just very inconvenient.
2014-05-29	Sort nixPath attributes	Eelco Dolstra	1	-0/+1

2014-05-26	Make the Nix search path declarative	Eelco Dolstra	1	-0/+32
	Nix search path lookups like <nixpkgs> are now desugared to ‘findFile nixPath <nixpkgs>’, where ‘findFile’ is a new primop. Thus you can override the search path simply by saying let nixPath = [ { prefix = "nixpkgs"; path = "/my-nixpkgs"; } ]; in ... <nixpkgs> ... In conjunction with ‘scopedImport’ (commit c273c15cb13bb86420dda1e5341a4e19517532b5), the Nix search path can be propagated across imports, e.g. let overrides = { nixPath = [ ... ] ++ builtins.nixPath; import = fn: scopedImport overrides fn; scopedImport = attrs: fn: scopedImport (overrides // attrs) fn; builtins = builtins // overrides; }; in scopedImport overrides ./nixos
2014-05-26	Add constant ‘nixPath’	Eelco Dolstra	1	-0/+11
	It contains the Nix expression search path as a list of { prefix, path } sets, e.g. [ { path = "/nix/var/nix/profiles/per-user/root/channels/nixos"; prefix = ""; } { path = "/etc/nixos/configuration.nix"; prefix = "nixos-config"; } { path = "/home/eelco/Dev/nix/inst/share/nix/corepkgs"; prefix = "nix"; } ]
2014-05-26	Add primop ‘scopedImport’	Eelco Dolstra	1	-0/+25
	‘scopedImport’ works like ‘import’, except that it takes a set of attributes to be added to the lexical scope of the expression, essentially extending or overriding the builtin variables. For instance, the expression scopedImport { x = 1; } ./foo.nix where foo.nix contains ‘x’, will evaluate to 1. This has a few applications: * It allows getting rid of function argument specifications in package expressions. For instance, a package expression like: { stdenv, fetchurl, libfoo }: stdenv.mkDerivation { ... buildInputs = [ libfoo ]; } can now we written as just stdenv.mkDerivation { ... buildInputs = [ libfoo ]; } and imported in all-packages.nix as: bar = scopedImport pkgs ./bar.nix; So whereas we once had dependencies listed in three places (buildInputs, the function, and the call site), they now only need to appear in one place. * It allows overriding builtin functions. For instance, to trace all calls to ‘map’: let overrides = { map = f: xs: builtins.trace "map called!" (map f xs); # Ensure that our override gets propagated by calls to # import/scopedImport. import = fn: scopedImport overrides fn; scopedImport = attrs: fn: scopedImport (overrides // attrs) fn; # Also update ‘builtins’. builtins = builtins // overrides; }; in scopedImport overrides ./bla.nix * Similarly, it allows extending the set of builtin functions. For instance, during Nixpkgs/NixOS evaluation, the Nixpkgs library functions could be added to the default scope. There is a downside: calls to scopedImport are not memoized, unlike import. So importing a file multiple times leads to multiple parsings / evaluations. It would be possible to construct the AST only once, but that would require careful handling of variables/environments.

2014-04-08	If a .drv cannot be parsed, show its path	Eelco Dolstra	1	-1/+1
	Otherwise you just get ‘expected string `Derive(['’ which isn't very helpful.

2014-04-04	Pass position information to primop calls	Eelco Dolstra	1	-90/+90
	For example: error: `tail' called on an empty list, at /home/eelco/Dev/nixpkgs/pkgs/applications/misc/hello/ex-2/default.nix:13:7
2014-04-04	Include position info in function application	Eelco Dolstra	1	-3/+3
	This allows error messages like: error: the anonymous function at `/etc/nixos/configuration.nix:1:1' called without required argument `foo', at `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/lib/modules.nix:77:59'
2014-01-21	Merge branch 'master' into make	Eelco Dolstra	1	-3/+3
	Conflicts: src/libexpr/eval.cc
2013-12-10	Bump language version for new storePath feature	Shea Levy	1	-1/+1
	This will allow e.g. channel expressions to use builtins.storePath IFF it is safe to do so without knowing if the path is valid yet. Signed-off-by: Shea Levy <shea@shealevy.com>

2013-11-19	Add a toJSON primop	Eelco Dolstra	1	-0/+14

2013-11-18	Add a primop unsafeGetAttrPos to return the position of an attribute	Eelco Dolstra	1	-1/+15

2013-10-28	Fix building without a garbage collector	Eelco Dolstra	1	-5/+5
	http://hydra.nixos.org/build/6695350
2013-10-28	Fix a segfault in genericClosure	Eelco Dolstra	1	-16/+25
	It kept temporary data in STL containers that were not scanned by Boehm GC, so Nix programs using genericClosure could randomly crash if the garbage collector kicked in at a bad time. Also make it a bit more efficient by copying points to values rather than values.
2013-10-28	Slightly optimize listToAttrs	Eelco Dolstra	1	-8/+8

2013-10-24	Rename "attribute sets" to "sets"	Eelco Dolstra	1	-15/+15
	We don't have any other kind of sets so calling them attribute sets is unnecessarily verbose.
2013-10-24	Add a typeOf primop	Eelco Dolstra	1	-3/+28
	We already have some primops for determining the type of a value, such as isString, but they're incomplete: for instance, there is no isPath. Rather than adding more isBla functions, the generic typeOf function returns a string representing the type of the argument (e.g. "int").
2013-10-17	Fold two stack trace messages in derivations	Eelco Dolstra	1	-4/+2
	Combined with the previous changes, stack traces involving derivations are now much less verbose, since something like while evaluating the builtin function `getAttr': while evaluating the builtin function `derivationStrict': while instantiating the derivation named `gtk+-2.24.20' at `/home/eelco/Dev/nixpkgs/pkgs/development/libraries/gtk+/2.x.nix:11:3': while evaluating the derivation attribute `propagatedNativeBuildInputs' at `/home/eelco/Dev/nixpkgs/pkgs/stdenv/generic/default.nix:78:17': while evaluating the attribute `outPath' at `/nix/store/212ngf4ph63mp6p1np2bapkfikpakfv7-nix-1.6/share/nix/corepkgs/derivation.nix:18:9': ... now reads while evaluating the attribute `propagatedNativeBuildInputs' of the derivation `gtk+-2.24.20' at `/home/eelco/Dev/nixpkgs/pkgs/development/libraries/gtk+/2.x.nix:11:3': ...
2013-10-17	Don't show <nix/derivation.nix> in stack traces	Eelco Dolstra	1	-1/+3
	Messages like while evaluating the attribute `outPath' at `/nix/store/212ngf4ph63mp6p1np2bapkfikpakfv7-nix-1.6/share/nix/corepkgs/derivation.nix:18:9': are redundant, because Nix already shows that it's evaluating a derivation: while instantiating the derivation named `firefox-24.0' at `/home/eelco/Dev/nixpkgs/pkgs/applications/networking/browsers/firefox/default.nix:131:5': while evaluating the derivation attribute `nativeBuildInputs' at `/home/eelco/Dev/nixpkgs/pkgs/stdenv/generic/default.nix:76:17':
2013-09-03	Get rid of the parse tree cache	Eelco Dolstra	1	-3/+2
	Since we already cache files in normal form (fileEvalCache), caching parse trees is redundant. Note that getting rid of this cache doesn't actually save much memory at the moment, because parse trees are currently not freed / GC'ed.
2013-09-02	Fix whitespace	Eelco Dolstra	1	-15/+15

2013-08-19	Store Nix integers as longs	Eelco Dolstra	1	-1/+1
	So on 64-bit systems, integers are now 64-bit. Fixes #158.
2013-08-02	Let the ordering operators also work on strings	Eelco Dolstra	1	-3/+6
	E.g. ‘"foo" < "bar"’ now works.
2013-03-08	Revert "Prevent config.h from being clobbered"	Eelco Dolstra	1	-0/+16
	This reverts commit 28bba8c44f484eae38e8a15dcec73cfa999156f6.

2012-12-04	Tiny optimisation in the filter primop	Eelco Dolstra	1	-2/+9

2012-11-27	Optionally ignore null-valued derivation attributes	Eelco Dolstra	1	-10/+22
	This allows adding attributes like attr = if stdenv.system == "bla" then something else null; without changing the resulting derivation on non-<bla> platforms. We once considered adding a special "ignore" value for this purpose, but using null seems more elegant.
2012-11-27	Add builtin constants ‘langVersion’ and ‘nixVersion’	Eelco Dolstra	1	-0/+10
	The integer constant ‘langVersion’ denotes the current language version. It gets increased every time a language feature is added/changed/removed. It's currently 1. The string constant ‘nixVersion’ contains the current Nix version, e.g. "1.2pre2980_9de6bc5".
