2004-03-19	* `null' is a normal form.	Eelco Dolstra	1	-8/+11

2004-02-19	* Resolve an ambiguity between ifs and attribute selection, e.g., `if	Eelco Dolstra	1	-3/+7
	b then x else y.z'.
2004-02-16	* Allow linking against an external Berkeley DB / ATerm library.	Eelco Dolstra	1	-2/+2

2004-02-16	* Inherited attributes in recursive attribute sets are in scope of the	Eelco Dolstra	2	-10/+18
	non-inherited attributes.
2004-02-04	* Extended the `inherit' syntax to optionally select attributes from	Eelco Dolstra	2	-8/+18
	other attribute sets, rather than the current scope. E.g., {inherit (pkgs) gcc binutils;} is equivalent to {gcc = pkgs.gcc; binutils = pkgs.binutils;} I am not so happy about the syntax.
2004-02-04	* An attribute set update operator (//). E.g.,	Eelco Dolstra	3	-0/+19
	{x=1; y=2; z=3;} // {y=4;} => {x=1; y=4; z=3;}
2004-02-04	* Use a map to lookup primops.	Eelco Dolstra	8	-38/+121
	* Various performance improvements in the evaluator. * Do not link against unused (and missing!) libraries (-lsglr, etc.).
2004-02-03	* Verify that all variables in a Nix expression are defined.	Eelco Dolstra	4	-21/+92

2004-02-02	* Added syntactic sugar to the construction of attribute sets to	Eelco Dolstra	6	-41/+78
	`inherit' variables from the surrounding lexical scope. E.g., {stdenv, libfoo}: derivation { builder = ./bla; inherit stdenv libfoo; xyzzy = 1; } is equivalent to {stdenv, libfoo}: derivation { builder = ./bla; stdenv = stdenv; libfoo = libfoo; xyzzy = 1; } Note that for mutually recursive attribute set definitions (`rec {...}'), this also works, that is, `rec {inherit x;}' is equivalent to `let {fresh = x; body = rec {x = fresh;};}', not `rec {x = x}'.
2004-01-30	* Doh!	Eelco Dolstra	1	-1/+3

2004-01-30	* Parser numbers again.	Eelco Dolstra	3	-2/+6
	* Include missing files in distributions.
2004-01-30	* Detect flex and bison; updated the manual.	Eelco Dolstra	1	-2/+4

2004-01-30	* Replaced the SDF parser by a substantially faster Bison/Flex	Eelco Dolstra	6	-251/+260
	parser (roughly 80x faster). The absolutely latest version of Bison (1.875c) is required for reentrant GLR support, as well as a recent version of Flex (say, 2.5.31). Note that most Unix distributions ship with the prehistoric Flex 2.5.4, which doesn't support reentrancy.
2004-01-29	* Optimised the SDF grammar.	Eelco Dolstra	2	-94/+15

2004-01-21	* Fixed a subtle uninitialised variable bug in ATermMaps copied from	Eelco Dolstra	1	-1/+3
	ATermMaps. Found thanks to Valgrind!
2004-01-15	* Catch SIGINT to terminate cleanly when the user tries to interrupt	Eelco Dolstra	3	-0/+8
	Nix. This is to prevent Berkeley DB from becoming wedged. Unfortunately it is not possible to throw C++ exceptions from a signal handler. In fact, you can't do much of anything except change variables of type `volatile sig_atomic_t'. So we set an interrupt flag in the signal handler and check it at various strategic locations in the code (by calling checkInterrupt()). Since this is unlikely to cover all cases (e.g., (semi-)infinite loops), sometimes SIGTERM may now be required to kill Nix.
2004-01-15	* Obsolete.	Eelco Dolstra	2	-290/+0

2004-01-05	* Implemented Eelco V.'s `nix-env -I' command to specify the default	Eelco Dolstra	1	-8/+10
	path of the Nix expression to be used with the import, upgrade, and query commands. For instance, $ nix-env -I ~/nixpkgs/pkgs/system/i686-linux.nix $ nix-env --query --available [aka -qa] sylpheed-0.9.7 bison-1.875 pango-1.2.5 subversion-0.35.1 ... $ nix-env -i sylpheed $ nix-env -u subversion There can be only one default at a time. * If the path to a Nix expression is a symlink, follow the symlink prior to resolving relative path references in the expression.
2003-11-25	* More `make dist' fixes.	Eelco Dolstra	1	-1/+2

2003-11-25	* Allow integer bindings in derivations.	Eelco Dolstra	2	-0/+8

2003-11-22	* Maintain integrity of the substitute and successor mappings when	Eelco Dolstra	3	-35/+55
	deleting a path in the store. * Allow absolute paths in Nix expressions. * Get nix-prefetch-url to work again. * Various other fixes.
2003-11-21	* Uninstallation.	Eelco Dolstra	1	-5/+11

2003-11-19	* nix-env: a tool to manage user environments.	Eelco Dolstra	1	-0/+2
	* Replace all directory reading code by a generic readDirectory() function.
2003-11-19	* Refactoring (step 2).	Eelco Dolstra	3	-126/+4

2003-11-19	* Refactoring: put the Nix expression evaluator in its own library so	Eelco Dolstra	13	-0/+1689
	that it can be used by multiple programs.
