2010-03-25	* Simplify @-patterns: only `{attrs}@name' or `name@{attrs}' are now	Eelco Dolstra	1	-1/+1
	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.
2008-08-14	* Added an experimental feature suggested by Andres: ellipses ("...")	Eelco Dolstra	1	-1/+1
	in attribute set pattern matches. This allows defining a function that takes at least the listed attributes, while ignoring additional attributes. For instance, {stdenv, fetchurl, fuse, ...}: stdenv.mkDerivation { ... }; defines a function that requires an attribute set that contains the specified attributes but ignores others. The main advantage is that we can then write in all-packages.nix aefs = import ../bla/aefs pkgs; instead of aefs = import ../bla/aefs { inherit stdenv fetchurl fuse; }; This saves a lot of typing (not to mention not having to update all-packages.nix with purely mechanical changes). It saves as much typing as the "args: with args;" style, but has the advantage that the function arguments are properly declared (not implicit in what the body of the "with" uses).
2008-08-14	* Refactoring: combine functions that take an attribute set and	Eelco Dolstra	1	-1/+1
	functions that take a single argument (plain lambdas) into one AST node (Function) that contains a Pattern node describing the arguments. Current patterns are single lazy arguments (VarPat) and matching against an attribute set (AttrsPat). This refactoring allows other kinds of patterns to be added easily, such as Haskell-style @-patterns, or list pattern matching.
2008-08-11	* Removed the "valid values" feature. Nobody uses it anyway.	Eelco Dolstra	1	-1/+1

2007-01-13	* Canonicalise ASTs in `nix-instantiate --eval': remove position	Eelco Dolstra	1	-1/+1
	info, sort attribute sets.
2006-10-17	* Fix the tests wrt the AST changes, i.e., Str(s) -> Str(s, []), and	Eelco Dolstra	1	-1/+1
	the semantic changes.
2006-10-11	* Removed URIs from the evaluator (NIX-66). They are now just another	Eelco Dolstra	1	-1/+1
	kind of notation for strings.
2006-07-24	* Refactoring to support domain checks.	Eelco Dolstra	1	-1/+1

2004-10-27	* Use `atdiff' instead of `cmp' for checking test output.	Eelco Dolstra	1	-1/+1
	* Don't use local file names in tests since they will produce different parse trees depending on the current directory.
2004-10-27	* Remove ancient Fix tests.	Eelco Dolstra	1	-0/+1
	* Add automated Nix expression language tests.
