2014-04-04	Pass position information to primop calls	Eelco Dolstra	4	-104/+104
	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	Remove unnecessary quotes around file names	Eelco Dolstra	1	-1/+1

2014-04-04	Include position info in function application	Eelco Dolstra	7	-22/+45
	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'
2014-04-01	Fix potential segfault	Eelco Dolstra	1	-2/+3
	The newEnv variable was accessed (via the dynamicEnv) pointer after it had gone out of scope. Fixes #234.
2014-03-30	boost::shared_ptr -> std::shared_ptr	Eelco Dolstra	1	-0/+1

2014-03-29	Drop pointless #include	Eelco Dolstra	1	-2/+0

2014-03-10	The expr of AttrNames/DynamicAttrDefs is always an ExprConcatStrings	Shea Levy	3	-12/+10

2014-03-10	If a dynamic attribute name evaluates to null, remove it from the set	Shea Levy	1	-1/+9

2014-03-05	Revert "Make ifs and asserts tail-recursive"	Eelco Dolstra	2	-11/+4
	This reverts commit 273322c7732093a354e86df82cf75d6604b8bce8.
2014-02-27	Correctly detect infinite recursion in function application	Eelco Dolstra	1	-2/+4
	If we're evaluating some application ‘v = f x’, we can't store ‘f’ temporarily in ‘v’, because if ‘f x’ refers to ‘v’, it will get ‘f’ rather than an infinite recursion error. Unfortunately, this breaks the tail call optimisation introduced in c897bac54954373f63511702731fe2cb23c0c98e. Fixes #217.
2014-02-26	Warn about missing -I paths	Eelco Dolstra	3	-5/+6
	Fixes #121. Note that we don't warn about missing $NIX_PATH entries because it's intended that some may be missing (cf. the default $NIX_PATH on NixOS, which includes paths like /etc/nixos/nixpkgs for backward compatibility).

	Signed-off-by: Shea Levy <shea@shealevy.com>
2014-01-14	Allow "bare" dynamic attrs	Shea Levy	2	-0/+3
	Now, in addition to a."${b}".c, you can write a.${b}.c (applicable wherever dynamic attributes are valid). Signed-off-by: Shea Levy <shea@shealevy.com>
2014-01-09	Update Makefiles	Eelco Dolstra	1	-4/+1

2013-12-31	Don't use any syntactic sugar for dynamic attrs	Shea Levy	4	-128/+68
	This doesn't change any functionality but moves some behavior out of the parser and into the evaluator in order to simplify the code. Signed-off-by: Shea Levy <shea@shealevy.com>
2013-12-31	Fold dynamic binds handling into addAttr	Shea Levy	1	-55/+35
	Since addAttr has to iterate through the AttrPath we pass it, it makes more sense to just iterate through the AttrNames in addAttr instead. As an added bonus, this allows attrsets where two dynamic attribute paths have the same static leading part (see added test case for an example that failed previously).

2013-12-31	Dynamic attrs	Shea Levy	4	-23/+238
	This adds new syntax for attribute names: * attrs."${name}" => getAttr name attrs * attrs ? "${name}" => isAttrs attrs && hasAttr attrs name * attrs."${name}" or def => if attrs ? "${name}" then attrs."${name}" else def * { "${name}" = value; } => listToAttrs [{ inherit name value; }] Of course, it's a bit more complicated than that. The attribute chains can be arbitrarily long and contain combinations of static and dynamic parts (e.g. attrs."${foo}".bar."${baz}" or qux), which is relatively straightforward for the getAttrs/hasAttrs cases but is more complex for the listToAttrs case due to rules about duplicate attribute definitions. For attribute sets with dynamic attribute names, duplicate static attributes are detected at parse time while duplicate dynamic attributes are detected when the attribute set is forced. So, for example, { a = null; a.b = null; "${"c"}" = true; } will be a parse-time error, while { a = {}; "${"a"}".b = null; c = true; } will be an eval-time error (technically that case could theoretically be detected at parse time, but the general case would require full evaluation). Moreover, duplicate dynamic attributes are not allowed even in cases where they would be with static attributes ({ a.b.d = true; a.b.c = false; } is legal, but { a."${"b"}".d = true; a."${"b"}".c = false; } is not). This restriction might be relaxed in the future in cases where the static variant would not be an error, but it is not obvious that that is desirable. Finally, recursive attribute sets with dynamic attributes have the static attributes in scope but not the dynamic ones. So rec { a = true; "${"b"}" = a; } is equivalent to { a = true; b = true; } but rec { "${"a"}" = true; b = a; } would be an error or use a from the surrounding scope if it exists. Note that the getAttr, getAttr or default, and hasAttr are all implemented purely in the parser as syntactic sugar, while attribute sets with dynamic attribute names required changes to the AST to be implemented cleanly. This is an alternative solution to and closes #167 Signed-off-by: Shea Levy <shea@shealevy.com>
2013-12-31	Add the ExprBuiltin Expr type to the AST	Shea Levy	4	-9/+36
	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).

2013-12-10	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>
2013-12-10	builtins.storePath: Try to substitute the path if it is not yet valid	Shea Levy	1	-2/+2

2013-11-25	Rename Makefile.new -> Makefile	Eelco Dolstra	1	-0/+0

2013-11-23	Use libnix as a prefix for all Nix libraries	Eelco Dolstra	1	-0/+2
	In particular "libutil" was always a problem because it collides with Glibc's libutil. Even if we install into $(libdir)/nix, the linker sometimes got confused (e.g. if a program links against libstore but not libutil, then ld would report undefined symbols in libstore because it was looking at Glibc's libutil).
2013-11-23	Drop the dependency on libgc in libmain	Eelco Dolstra	2	-0/+22
	Instead, libexpr now depends on libgc. This means commands like nix-store that don't do any evaluation no longer require libgc.

2013-11-18	Add a primop unsafeGetAttrPos to return the position of an attribute	Eelco Dolstra	4	-6/+37

2013-11-18	Add a symbol __curPos that expands to the current source location	Eelco Dolstra	5	-2/+37
	I.e. an attribute set { file = <string>; line = <int>; column = <int>; }.
2013-11-18	Support quoted attribute names in -A	Eelco Dolstra	1	-10/+34
	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	Make function calls show up in stack traces again	Eelco Dolstra	1	-20/+28
	Note that adding --show-trace prevents functions calls from being tail-recursive, so an expression that evaluates without --show-trace may fail with a stack overflow if --show-trace is given.
