2014-09-22	Add a function ‘valueSize’	Eelco Dolstra
	It returns the size of value, including all other values and environments reachable from it. It is intended for debugging memory consumption issues.
2014-09-19	Inline Bindings::find()	Eelco Dolstra

2014-09-19	Store Attrs inside Bindings	Eelco Dolstra
	This prevents a double allocation per attribute set.
2014-09-17	Add some instrumentation for debugging GC leaks	Eelco Dolstra

2014-09-02	Fix boost::too_many_args error	Eelco Dolstra
	Fixes #333.
2014-08-20	Use proper quotes everywhere	Eelco Dolstra

2014-08-13	Fix warning about non-existant -I directories	Eelco Dolstra

2014-06-10	== operator: Ignore string context	Eelco Dolstra
	There really is no case I can think of where taking the context into account is useful. Mostly it's just very inconvenient.
2014-05-26	Remove ExprBuiltin	Eelco Dolstra
	It's slower than ExprVar since it doesn't compute a static displacement. Since we're not using the throw primop in the implementation of <...> anymore, it's also not really needed.
2014-05-26	Ensure that -I flags get included in nixPath	Eelco Dolstra
	Also fixes #261.

2014-04-04	Include position info in function application	Eelco Dolstra
	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'

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

2014-03-05	Revert "Make ifs and asserts tail-recursive"	Eelco Dolstra
	This reverts commit 273322c7732093a354e86df82cf75d6604b8bce8.
2014-02-27	Correctly detect infinite recursion in function application	Eelco Dolstra
	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.
2014-01-21	Merge branch 'master' into make	Eelco Dolstra
	Conflicts: src/libexpr/eval.cc
2013-12-31	Don't use any syntactic sugar for dynamic attrs	Shea Levy
	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	Dynamic attrs	Shea Levy
	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
	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).

2013-11-23	Drop the dependency on libgc in libmain	Eelco Dolstra
	Instead, libexpr now depends on libgc. This means commands like nix-store that don't do any evaluation no longer require libgc.
2013-11-23	Initialise Boehm GC only once	Eelco Dolstra

2013-11-19	Add a toJSON primop	Eelco Dolstra

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

2013-11-18	Add a symbol __curPos that expands to the current source location	Eelco Dolstra
	I.e. an attribute set { file = <string>; line = <int>; column = <int>; }.
2013-11-12	Make function calls show up in stack traces again	Eelco Dolstra
	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.
2013-11-12	Make function calls tail-recursive	Eelco Dolstra

2013-11-12	Make ifs and asserts tail-recursive	Eelco Dolstra
	The local Value object prevented g++ from making a tail call. Not clear why. In any case, not using a temporary makes g++ do the tail call.
2013-11-12	Get rid of an intermediary on the stack	Eelco Dolstra

2013-10-28	Slightly optimize listToAttrs	Eelco Dolstra

2013-10-24	Rename "attribute sets" to "sets"	Eelco Dolstra
	We don't have any other kind of sets so calling them attribute sets is unnecessarily verbose.
2013-10-24	Remove unnecessary call to forceStringNoCtx	Eelco Dolstra

2013-10-24	Don't require NIX_SHOW_STATS for NIX_COUNT_CALLS	Eelco Dolstra

2013-10-23	Memoize evalFile() lookups under both the original and resolved name	Eelco Dolstra
	Previously we only used the resolved name, causing repeated resolution (e.g. /dir to /dir/default.nix).
2013-10-17	Don't show <nix/derivation.nix> in stack traces	Eelco Dolstra
	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':
2013-10-17	Revert the behaviour of antiquoted paths to pre-Nix 1.6	Eelco Dolstra
	Commit 159e621d1a9c4391b53f3d822109c36931934698 accidentally changed the behaviour of antiquoted paths, e.g. "${/foo}/bar" used to evaluate to "/nix/store/<hash>-foo/bar" (where /foo gets copied to the store), but in Nix 1.6 it evaluates to "/foo/bar". This is inconsistent, since " ${/foo}/bar" evaluates to " /nix/store/<hash>-foo/bar". So revert to the old behaviour.
2013-10-08	printStats(): Print the size of the symbol table in bytes	Eelco Dolstra

2013-10-08	Deduplicate filenames in Pos	Eelco Dolstra
	This saves ~4 MiB of RAM for NixOS system instantiation, and ~18 MiB for "nix-env -qa".
2013-10-08	Treat undefined variable errors consistently	Eelco Dolstra
	Previously, a undefined variable inside a "with" caused an EvalError (which can be caught), while outside, it caused a ParseError (which cannot be caught). Now both cause an UndefinedVarError (which cannot be caught).
2013-10-08	Show the exact position of undefined variables	Eelco Dolstra
	In particular, undefined variable errors in a "with" previously didn't show any position information, so this should help a lot in those cases.
2013-10-08	Remove some unused functions	Eelco Dolstra
