Eelco Dolstra 5cabd47394 * Allow function argument default values to refer to other arguments
of the function.  Implements NIX-45.
2006-05-08 12:52:47 +00:00
Eelco Dolstra ae55e79541 * More tests. 2006-05-02 11:20:55 +00:00
Eelco Dolstra dca43ef795 * Tests for NIX-45. 2006-05-02 11:15:04 +00:00
Eelco Dolstra 0064599a27 * String interpolation. Expressions like
"--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.

Eelco Dolstra 6cecad2be0 * Allow string concatenations involving derivations, e.g.,
configureFlags = "--with-freetype2-library="
      + freetype + "/lib";

Eelco Dolstra fa95f4be3f * More test coverage. 2006-03-01 16:26:13 +00:00
Eelco Dolstra 44409f52c1 * "Fix" the test, since we cannot feasibly support the intended semantics. 2005-11-17 11:58:22 +00:00
Eelco Dolstra 1f285cf556 * Scoping bug in `with'. 2005-11-04 14:50:33 +00:00
Eelco Dolstra 991a130b1e * Added a list concatenation operator:
[1 2 3] ++ [4 5 6] => [1 2 3 4 5 6]
2005-07-25 15:05:34 +00:00
Eelco Dolstra 040140dd1c * Added a primop `removeAttrs' to remove attributes from a set, e.g.,
`removeAttrs attrs ["x", "y"]' returns the set `attrs' with the
  attributes named `x' and `y' removed.  It is not an error for the
  named attributes to be missing from the input set.

Eelco Dolstra 08df443618 * Check for duplicate attributes and formal parameters in Nix
expressions.
2005-03-10 11:33:46 +00:00
Eelco Dolstra ed09821859 * Use atdiff' instead of cmp' for checking test output.
* Don't use local file names in tests since they will produce
  different parse trees depending on the current directory.
2004-10-27 13:12:58 +00:00
Eelco Dolstra 3277c9432a * Bug fix in parsing of /* ... */ comments; due to longest match
regexp there could be only one such comment per file.
2004-10-27 13:00:31 +00:00
Eelco Dolstra 463e2817c5 * Remove ancient Fix tests.
* Add automated Nix expression language tests.
