2007-01-13	* Canonicalise ASTs in `nix-instantiate --eval': remove position	Eelco Dolstra	1	-0/+5
	info, sort attribute sets.
2006-10-16	* Big cleanup of the semantics of paths, strings, contexts, string	Eelco Dolstra	1	-0/+13
	concatenation and string coercion. This was a big mess (see e.g. NIX-67). Contexts are now folded into strings, so that they don't cause evaluation errors when they're not expected. The semantics of paths has been clarified (see nixexpr-ast.def). toString() and coerceToString() have been merged. Semantic change: paths are now copied to the store when they're in a concatenation (and in most other situations - that's the formalisation of the meaning of a path). So "foo " + ./bla evaluates to "foo /nix/store/hash...-bla", not "foo /path/to/current-dir/bla". This prevents accidental impurities, and is more consistent with the treatment of derivation outputs, e.g., `"foo " + bla' where `bla' is a derivation. (Here `bla' would be replaced by the output path of `bla'.)
2006-09-20	* Shut up a warning.	Eelco Dolstra	1	-0/+1

2006-09-04	* Remove unnecessary inclusions of aterm2.h.	Eelco Dolstra	1	-2/+0

2006-09-04	* Use a proper namespace.	Eelco Dolstra	1	-1/+7
	* Optimise header file usage a bit. * Compile the parser as C++.
2006-08-23	* New primop: abort "error message".	Eelco Dolstra	1	-0/+1

2006-08-04	* Fix a few warnings.	Eelco Dolstra	1	-1/+1

2006-07-28	* `nix-instantiate --print-args': print out the valid values for	Eelco Dolstra	1	-0/+2
	functions arguments that have a domain.
2006-07-24	* Refactoring to support domain checks.	Eelco Dolstra	1	-0/+3

2006-07-19	* Better error messages (especially wrt types).	Eelco Dolstra	1	-0/+7

2006-05-04	* Use the new ATermMap.	Eelco Dolstra	1	-38/+1

2006-05-02	* Use a linked list of substitutions. This reduces the amount of	Eelco Dolstra	1	-1/+26
	copying.
2006-03-06	* GCC 4.1 compatibility.	Eelco Dolstra	1	-1/+1

2005-05-08	* ATermMap needs an assignment operator, otherwise we are screwed.	Eelco Dolstra	1	-0/+5

2005-04-10	* Primop `__currentSystem' to return the current platform identifier.	Eelco Dolstra	1	-6/+0

2004-10-26	* Don't use ATmake / ATmatch anymore, nor the ATMatcher class.	Eelco Dolstra	1	-5/+2
	Instead we generate data bindings (build and match functions) for the constructors specified in `constructors.def'. In particular this removes the conversions between AFuns and strings, and Nix expression evaluation now seems 3 to 4 times faster.
2004-10-26	* String/path concatenation operator (`+').	Eelco Dolstra	1	-0/+6

2004-08-04	* Allow primops with more that 1 arguments.	Eelco Dolstra	1	-0/+6

2004-04-05	* When something goes wrong in the evaluation of a Nix expression,	Eelco Dolstra	1	-1/+5
	print a nice backtrace of the stack, rather than vomiting a gigantic (and useless) aterm on the screen. Example: error: while evaluating file `.../pkgs/system/test.nix': while evaluating attribute `subversion' at `.../pkgs/system/all-packages-generic.nix', line 533: while evaluating function at `.../pkgs/applications/version-management/subversion/default.nix', line 1: assertion failed at `.../pkgs/applications/version-management/subversion/default.nix', line 13 Since the Nix expression language is lazy, the trace may be misleading. The purpose is to provide a hint as to the location of the problem.
2004-02-04	* Use a map to lookup primops.	Eelco Dolstra	1	-1/+8
	* 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	1	-0/+4

2003-11-19	* Refactoring: put the Nix expression evaluator in its own library so	Eelco Dolstra	1	-0/+75
	that it can be used by multiple programs.
