2010-04-14	* Change the semantics of "with" so that inner "withs" take	Eelco Dolstra	2	-25/+2
	precedence, i.e. `with {x=1;}; with {x=2;}; x' evaluates to 2'. This has a simpler implementation and seems more natural. There doesn't seem to be any code in Nixpkgs or NixOS that relies on the old behaviour.
2010-04-13	* Use std::tr1::unordered_set instead of std::set for the symbol	Eelco Dolstra	2	-1/+8
	table. This gives a 10% speed increase on `nix-instantiate /etc/nixos/nixos -A system --readonly-mode'.
2010-04-13	* Evaluate lets directly (i.e. without desugaring to `rec { attrs...;	Eelco Dolstra	5	-1/+45
	<let-body> = e; }.<let-body>). This prevents the unnecessary allocation of an attribute set.
2010-04-13	* Use a symbol table to represent identifiers and attribute names	Eelco Dolstra	14	-99/+226
	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	* Finished the ATerm-less parser.	Eelco Dolstra	5	-100/+66

2010-04-12	* Indented strings.	Eelco Dolstra	6	-69/+64

2010-04-12	* More missing constructs.	Eelco Dolstra	6	-137/+160

2010-04-12	* Don't use ATerms for the abstract syntax trees anymore. Not	Eelco Dolstra	16	-569/+684
	finished yet.
2010-04-12	* Don't use ATerms to represent integers in the lexer.	Eelco Dolstra	2	-3/+5

2010-04-12	* Hack to support builderDefs expressions.	Eelco Dolstra	1	-1/+7

2010-04-12	* Doh.	Eelco Dolstra	1	-1/+1

2010-04-12	(no commit message)	Eelco Dolstra	1	-55/+58

2010-04-09	* Keep more statistics about stack space usage.	Eelco Dolstra	2	-43/+78
	* Reduce stack space usage.
2010-04-08	* Remove a lot of dead code.	Eelco Dolstra	3	-762/+9

2010-04-08	* Fix blackholing. If evaluation fails due to an assertion failure,	Eelco Dolstra	1	-2/+8
	then the blackhole has to be removed to ensure that repeated evaluation of the same value gives an assertion failure again rather than an "infinite recursion" error.
2010-04-07	* Update autoCallFunction() and findAlongAttrPath().	Eelco Dolstra	8	-102/+81

2010-04-07	* expr-to-xml -> value-to-xml.	Eelco Dolstra	4	-7/+7

2010-04-07	* Implemented the primops necessary for generating the NixOS manual.	Eelco Dolstra	7	-144/+157

2010-04-06	* In eval(), don't use the target value `v' as a temporary.	Eelco Dolstra	1	-13/+17
	Overwriting `v' breaks when the expression evaluation to an assertion failure or throw.
2010-04-01	* Removed the `~' operator.	Eelco Dolstra	2	-2/+0

2010-04-01	* Quick hack to make coerceToString work more or less correctly on	Eelco Dolstra	1	-1/+4
	nested lists. `nix-instantiate' can now evaluate the NixOS system derivation attribute correctly (in 2.1s on my laptop vs. 6.2s for the trunk).
2010-04-01	* Improve sharing.	Eelco Dolstra	3	-19/+25

2010-04-01	* Functions are incomparable.	Eelco Dolstra	1	-6/+13

2010-04-01	* Make `derivation' lazy again for performance. It also turns out	Eelco Dolstra	3	-37/+17
	that there are some places in Nixpkgs (php_configurable / composableDerivation, it seems) that call `derivation' with incorrect arguments (namely, the `name' attribute missing) but get away with it because of laziness.
2010-03-31	* Fixed the trace primop and path comparison.	Eelco Dolstra	2	-41/+11
	* Removed exprToString and stringToExpr because there is no ATerm representation to work on anymore (and exposing the internals of the evaluator like this is not a good idea anyway).
2010-03-31	* Handle string contexts. `nix-instantiate' can now correctly compute	Eelco Dolstra	3	-65/+28
	the `firefoxWrapper' attribute in Nixpkgs, and it's about 3 times faster than the trunk :-)
2010-03-31	* Get nix-env to compile.	Eelco Dolstra	1	-26/+19

2010-03-31	* Cache parse trees to prevent repeated parsing of imported Nix	Eelco Dolstra	3	-7/+10
	expressions.
2010-03-31	* Implemented derivations.	Eelco Dolstra	5	-191/+167

2010-03-31	* Implemented `rec { inherit ...; }'.	Eelco Dolstra	2	-0/+17

2010-03-31	* Compare nulls.	Eelco Dolstra	1	-2/+5

2010-03-30	* More primops.	Eelco Dolstra	3	-91/+109

2010-03-30	* More operators / primops.	Eelco Dolstra	4	-184/+138

2010-03-30	* More primops.	Eelco Dolstra	3	-183/+91

2010-03-30	* More primops.	Eelco Dolstra	4	-96/+55

2010-03-30	* Implemented `map'.	Eelco Dolstra	4	-108/+139

2010-03-30	* Make `import' work.	Eelco Dolstra	4	-62/+141

2010-03-29	* Started integrating the new evaluator.	Eelco Dolstra	7	-708/+736

2010-03-28	(no commit message)	Eelco Dolstra	1	-53/+51

2010-03-28	* Implemented multi-argument primops.	Eelco Dolstra	1	-9/+36

2010-03-26	* Primops (not yet finished).	Eelco Dolstra	1	-16/+114

2010-03-26	* Implemented the `==' and `!=' operators. These now use a deep	Eelco Dolstra	1	-0/+67
	equality test, so they also work for (finite) attribute sets and lists.
2010-03-25	* Measure stack usage.	Eelco Dolstra	1	-3/+11

2010-03-25	* Implemented lists.	Eelco Dolstra	1	-7/+63

2010-03-25	* Quick and dirty implementation of `with'. `with e1; e2' is	Eelco Dolstra	2	-6/+56
	basically desugared to `let <with> = e1; e2', and `lookupVar' looks in each <with> in the environment chain for an attribute with the specified name.
2010-03-25	* Don't convert variable names to strings.	Eelco Dolstra	1	-12/+15
