2006-09-04	* Compile the lexer as C++ code. Remove all the redundant C/C++	Eelco Dolstra	1	-6/+38
	marshalling code.
2006-09-04	* Use a proper namespace.	Eelco Dolstra	1	-2/+6
	* Optimise header file usage a bit. * Compile the parser as C++.
2006-09-01	* Allow "$" in strings as long as they are not followed by "{". (Too	Eelco Dolstra	1	-1/+5
	bad flex doesn't have lexical restrictions, the current solution isn't quite right...)
2006-08-16	* Handle carriage returns. Fixes NIX-53.	Eelco Dolstra	1	-2/+6

2006-05-01	* Disallow unescaped $ in string literals.	Eelco Dolstra	1	-4/+1

2006-05-01	* String interpolation. Expressions like	Eelco Dolstra	1	-9/+32
	"--with-freetype2-library=" + freetype + "/lib" can now be written as "--with-freetype2-library=${freetype}/lib" An arbitrary expression can be enclosed within ${...}, not just identifiers. * Escaping in string literals: \n, \r, \t interpreted as in C, any other character following \ is interpreted as-is. * Newlines are now allowed in string literals.
2005-07-25	* Added a list concatenation operator:	Eelco Dolstra	1	-0/+1
	[1 2 3] ++ [4 5 6] => [1 2 3 4 5 6]
2004-10-27	* Bug fix in parsing of /* ... */ comments; due to longest match	Eelco Dolstra	1	-1/+1
	regexp there could be only one such comment per file.
2004-10-25	* New language feature: with expressions.	Eelco Dolstra	1	-0/+1
	The expression `with E1; E2' evaluates to E2 with all bindings in the attribute set E1 substituted. E.g., with {x = 123;}; x evaluates to 123. That is, the attribute set E1 is in scope in E2. This is particularly useful when importing files containing lots definitions. E.g., instead of let { inherit (import ./foo.nix) a b c d e f; body = ... a ... f ...; } we can now say with import ./foo.nix; ... a ... f ... I.e., we don't have to say what variables should be brought into scope.
2004-03-28	* Added plain lambdas, e.g., `let { id = x: x; const = x: y: x; }'.	Eelco Dolstra	1	-1/+1
	`bla:' is now no longer parsed as a URL. * Re-enabled support for the `args' attribute in derivations to specify command line arguments to the builder, e.g., ... builder = /usr/bin/python; args = ["-c" ./builder.py]; ...
2004-02-04	* An attribute set update operator (//). E.g.,	Eelco Dolstra	1	-0/+1
	{x=1; y=2; z=3;} // {y=4;} => {x=1; y=4; z=3;}
2004-02-02	* Added syntactic sugar to the construction of attribute sets to	Eelco Dolstra	1	-0/+1
	`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	* Parser numbers again.	Eelco Dolstra	1	-1/+4
	* Include missing files in distributions.
2004-01-30	* Replaced the SDF parser by a substantially faster Bison/Flex	Eelco Dolstra	1	-0/+78
	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.
