Eelco Dolstra c52dda95a6 * Bug: check that term is an application. 2004-10-26 23:30:18 +00:00
Eelco Dolstra 5fe9222b36 * Don't use ATmake / ATmatch anymore, nor the ATMatcher class. 
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 22:54:26 +00:00
Eelco Dolstra eb8284ddaa * Evaluate argument to `import'. 2004-10-26 17:10:09 +00:00
Eelco Dolstra 033d7c6593 * Doh! 2004-10-26 17:04:55 +00:00
Eelco Dolstra 9fa07b376d * String/path concatenation operator (`+'). 2004-10-26 17:01:35 +00:00
Eelco Dolstra ee401afad8 * Mode --parse-only' to parse the input (on stdin, -'), and print 
out the AST as an ATerm.
* Mode `--eval-only' to parse and evaluate the input, and print the
  resulting normal form as an ATerm.

Neither of these modes require store/DB write permission.
 2004-10-26 16:59:36 +00:00
Eelco Dolstra 37d7abd694 * New language feature: with expressions. 
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.
