2010-04-15	* Store lists as lists of pointers to values rather than as lists of	Eelco Dolstra	1	-0/+1
	values. This improves sharing and gives another speed up. Evaluation of the NixOS system attribute is now almost 7 times faster than the old evaluator.
2010-04-14	* Implemented inherit.	Eelco Dolstra	1	-1/+4

2010-04-14	* Implemented withs.	Eelco Dolstra	1	-1/+2

2010-04-14	* After parsing, compute level/displacement pairs for each variable	Eelco Dolstra	1	-2/+3
	use site, allowing environments to be stores as vectors of values rather than maps. This should speed up evaluation and reduce the number of allocations.
2010-04-13	* Use a symbol table to represent identifiers and attribute names	Eelco Dolstra	1	-1/+24
	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	1	-2/+2

2010-04-12	* Indented strings.	Eelco Dolstra	1	-0/+1

2010-04-12	* More missing constructs.	Eelco Dolstra	1	-3/+5

2010-04-12	* Don't use ATerms for the abstract syntax trees anymore. Not	Eelco Dolstra	1	-10/+12
	finished yet.

2010-04-07	* Implemented the primops necessary for generating the NixOS manual.	Eelco Dolstra	1	-1/+4

2010-03-31	* Implemented `rec { inherit ...; }'.	Eelco Dolstra	1	-0/+3

2010-03-30	* More operators / primops.	Eelco Dolstra	1	-0/+1

2010-03-30	* More primops.	Eelco Dolstra	1	-2/+4

2010-03-30	* Implemented `map'.	Eelco Dolstra	1	-0/+2

2010-03-30	* Make `import' work.	Eelco Dolstra	1	-1/+3

2010-03-29	* Started integrating the new evaluator.	Eelco Dolstra	1	-661/+1

2010-03-28	* Strings.	Eelco Dolstra	1	-0/+45

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	1	-6/+55
	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

2010-03-25	* Implement blackholing.	Eelco Dolstra	1	-8/+9

2010-03-25	* Implement `...' and default function arguments.	Eelco Dolstra	1	-7/+31

2010-03-25	* Simplify @-patterns: only `{attrs}@name' or `name@{attrs}' are now	Eelco Dolstra	1	-98/+38
	allowed. So `name1@name2', `{attrs1}@{attrs2}' and so on are now no longer legal. This is no big loss because they were not useful anyway. This also changes the output of builtins.toXML for @-patterns slightly.
2010-03-24	* Implemented attribute set pattern matches.	Eelco Dolstra	1	-13/+117

2010-03-24	* Store values in environments.	Eelco Dolstra	1	-64/+66

2010-03-24	* Reduce the number of value allocations in eval() by moving	Eelco Dolstra	1	-26/+38
	responsibility for allocation of the result to the caller.
2010-03-24	* Plain lambdas.	Eelco Dolstra	1	-2/+38

2010-03-23	* Start of an evaluator that uses call-by-need (with thunk updating)	Eelco Dolstra	1	-0/+191
	instead of (memoised) call-by-name.
