2013-12-31 Add the ExprBuiltin Expr type to the ASTShea Levy2-0/+4
Certain desugaring schemes may require the parser to use some builtin function to do some of the work (e.g. currently `throw` is used to lazily cause an error if a `<>`-style path is not in the search path) Unfortunately, these names are not reserved keywords, so an expression that uses such a syntactic sugar will not see the expected behavior (see tests/lang/eval-okay-redefine-builtin.nix for an example). This adds the ExprBuiltin AST type, which when evaluated uses the value from the rootmost variable scope (which of course is initialized internally and can't shadow any of the builtins).

2013-11-19 Add a toJSON primopEelco Dolstra2-0/+12
2013-11-18 Add a primop unsafeGetAttrPos to return the position of an attributeEelco Dolstra2-0/+7
2013-11-18 Add a symbol __curPos that expands to the current source locationEelco Dolstra2-0/+6
I.e. an attribute set { file = <string>; line = <int>; column = <int>; }.
2013-11-18 Support quoted attribute names in -AEelco Dolstra2-4/+4
This is requires if you have attribute names with dots in them. So you can now say: $ nix-instantiate '<nixos>' -A 'config.systemd.units."postgresql.service".text' --eval-only Fixes #151.
2013-11-12 Add a test to check that tail calls run in bounded stack spaceEelco Dolstra2-0/+4
2013-10-24 Rename "attribute sets" to "sets"Eelco Dolstra1-1/+1
We don't have any other kind of sets so calling them attribute sets is unnecessarily verbose.
2013-10-24 Add a test of the type primopsEelco Dolstra2-0/+24
2013-10-17 Fix testEelco Dolstra1-1/+2
2013-10-17 Test string semantics a bit moreEelco Dolstra2-3/+6
2013-10-17 Add a test for type correctness of antiquotesEelco Dolstra3-0/+3
Antiquotes should evaluate to strings or paths. This is usually checked, except in the case where the antiquote makes up the entire string, as in "${expr}". This is optimised to expr, which discards the runtime type checks / coercions.
2013-10-16 Add a regression test for correct path antiquotation behaviorEelco Dolstra1-0/+4
This broke in Nix 1.6.

2013-08-26 Simplify inherited attribute handlingShea Levy2-0/+25
This reduces the difference between inherited and non-inherited attribute handling to the choice of which env to use (in recs and lets) by setting the AttrDef::e to a new ExprVar in the parser rather than carrying a separate AttrDef::v VarRef member. As an added bonus, this allows inherited attributes that inherit from a with to delay forcing evaluation of the with's attributes. Signed-off-by: Shea Levy <shea@shealevy.com>
2013-08-26 Fix typos, especially those that end up in the Nix manualIvan Kozik1-1/+1
2013-08-02 Let the ordering operators also work on stringsEelco Dolstra2-1/+6
E.g. ‘"foo" < "bar"’ now works.
2013-08-02 Add comparison operators ‘<’, ‘<=’, ‘>’ and ‘>=’Eelco Dolstra2-1/+24
2013-08-02 Add integer ‘-’, ‘*’ and ‘/’ operatorsEelco Dolstra3-1/+11
2013-08-02 Add a unary integer negation operatorEelco Dolstra2-2/+7
This allows saying "-1" instead of "builtins.sub 0 1".

2013-07-31 Delay evaulation of `with` attrs until a variable lookup needs themShea Levy2-0/+27
Evaluation of attribute sets is strict in the attribute names, which means immediate evaluation of `with` attribute sets rules out some potentially interesting use cases (e.g. where the attribute names of one set depend in some way on another but we want to bring those names into scope for some values in the second set). The major example of this is overridable self-referential package sets (e.g. all-packages.nix). With immediate `with` evaluation, the only options for such sets are to either make them non-recursive and explicitly use the name of the overridden set in non-overridden one every time you want to reference another package, or make the set recursive and use the `__overrides` hack. As shown in the test case that comes with this commit, though, delayed `with` evaluation allows a nicer third alternative. Signed-off-by: Shea Levy <shea@shealevy.com>
2013-07-01 Add support for uncompressed NARs in binary cachesEelco Dolstra1-1/+1
Issue NixOS/hydra#102.
2013-06-20 Don't keep "disabled" substituters runningEelco Dolstra2-0/+2
For instance, it's pointless to keep copy-from-other-stores running if there are no other stores, or download-using-manifests if there are no manifests. This also speeds things up because we don't send queries to those substituters.

AFAIK nobody uses this, setuid binaries are evil, and there is no good reason why people can't just run the daemon.
2012-09-27 Allow dashes in identifiersEelco Dolstra1-2/+2
In Nixpkgs, the attribute in all-packages.nix corresponding to a package is usually equal to the package name. However, this doesn't work if the package contains a dash, which is fairly common. The convention is to replace the dash with an underscore (e.g. "dbus-lib" becomes "dbus_glib"), but that's annoying. So now dashes are valid in variable / attribute names, allowing you to write: dbus-glib = callPackage ../development/libraries/dbus-glib { }; and buildInputs = [ dbus-glib ]; Since we don't have a negation or subtraction operation in Nix, this is unambiguous.

2012-09-12 Handle gc-keep-outputs and gc-keep-derivations both enabledEelco Dolstra1-1/+3
If the options gc-keep-outputs and gc-keep-derivations are both enabled, you can get a cycle in the liveness graph. There was a hack to handle this, but it didn't work with multiple-output derivations, causing the garbage collector to fail with errors like ‘error: cannot delete path `...' because it is in use by `...'’. The garbage collector now handles strongly connected components in the liveness graph as a unit and decides whether to delete all or none of the paths in an SCC.
2012-09-12 Fix test failure on DarwinEelco Dolstra2-1/+2
Apparently our DBD::SQLite links against /usr/lib/libsqlite3.dylib, which is an old version that doesn't respect foreign key constraints. So manifests/cache.sqlite doesn't get updated properly when a manifest disappears. We should fix our DBD::SQLite, but in the meantime this will fix the test. http://hydra.nixos.org/build/3017959
