Eelco Dolstra	1c9c0a5a46	* Added syntactic sugar to the construction of attribute sets to ... `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}'.	2004-02-02 21:39:33 +00:00
Eelco Dolstra	619f20775d	* Parser numbers again. ... * Include missing files in distributions.	2004-01-30 17:06:03 +00:00
Eelco Dolstra	c5baaafae6	* Replaced the SDF parser by a substantially faster Bison/Flex ... 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.	2004-01-30 15:21:42 +00:00
