2004-04-05 * When something goes wrong in the evaluation of a Nix expression,Eelco Dolstra1-1/+1
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 Dolstra1-33/+1
* Various performance improvements in the evaluator. * Do not link against unused (and missing!) libraries (-lsglr, etc.).
2003-12-01 * Help text for all (non-script) programs, so no more:Eelco Dolstra1-3/+8
$ nix-instantiate --help error: unknown flag `--help` Try `nix-instantiate --help' for more information. :-)

2003-11-22 * Maintain integrity of the substitute and successor mappings whenEelco Dolstra1-3/+4
