* Primop `pathExists' to check for path existence.

e47e0c2dbe * Builtin function `getEnv' for getting environment variables. 2006-09-24 17:48:41 +00:00

df8873e14a * lessThan primitive for integer comparison. 2006-09-24 15:21:48 +00:00
Eelco Dolstra
2ab4bc44c7 * Builtin function `add' to add integers.
* Put common test functions in tests/lang/lib.nix.

Eelco Dolstra
d315210612 * Added a builtin function `isList' to test whether a value is a list.
With this primitive, a list-flattening function can be implemented
  (NIX-55, example is in tests/lang/eval-okay-flatten.nix).

c02a44183f * Builtin functions head' and tail' to return the head and tail of
list.  Useful for lots of things, such as implementing a fold
  function (see NIX-30, example is in tests/lang/eval-okay-list.nix).
2006-09-22 14:46:36 +00:00
Eelco Dolstra
8a1ab709a4 * New builtin functions builtins.{hasAttr, getAttr} to check for
attribute existence and to return an attribute from an attribute
  set, respectively.  Example: `hasAttr "foo" {foo = 1;}'.  They
  differ from the `?' and `.' operators in that the attribute name is
  an arbitrary expression.  (NIX-61)

bafc1690fc * Move setuid stuff to libutil.
* Install libexpr header files.

e5a6c09b12 * Install header files in /nix/include/nix. 2006-09-04 22:41:36 +00:00

4be5443882 * Remove unnecessary inclusions of aterm2.h. 2006-09-04 22:08:40 +00:00
Eelco Dolstra
e3ce954582 * Compile the lexer as C++ code. Remove all the redundant C/C++
marshalling code.

Eelco Dolstra
75068e7d75 * Use a proper namespace.
* Optimise header file usage a bit.
* Compile the parser as C++.

aab8812732 * Store the Nix libraries in ${libdir}/nix instead of ${libdir}. 2006-09-04 15:12:24 +00:00
Eelco Dolstra
7974aae81c * New primop: builtins.toFile, which writes a string into the store
and returns its path.  This can be used to (for instance) write
  builders inside a Nix expression, e.g.,

  stdenv.mkDerivation {
    builder = "
      source $stdenv/setup
      ...
    ";
    ...
  }
2006-09-01 12:07:31 +00:00
Eelco Dolstra
de90fdf908 * Allow "$" in strings as long as they are not followed by "{". (Too
bad flex doesn't have lexical restrictions, the current solution
  isn't quite right...)

f93f7b75be * Okay, that's a bit harder than expected. 2006-08-30 13:10:04 +00:00

3151bdea55 * Uninitialised variable. 2006-08-30 12:00:27 +00:00
Eelco Dolstra
547b119f25 * Support singleton values and nested lists again in `args', but print
a warning.

2132d9ddeb * Fix the ~ operator. 2006-08-29 15:29:38 +00:00
Eelco Dolstra
1ec9f55741 * In toString, deal with nested lists properly (i.e., flatten them). 2006-08-28 21:47:42 +00:00
Eelco Dolstra
1fca76870b * Removed processBinding, instead we now apply toString to all
derivation attributes to flatten them into strings.  This is
  possible since string can nowadays be wrapped in contexts that
  describe the derivations/sources referenced by the evaluation of the
  string.

4b66cebe7b * Remove those storePath attribute sets, we don't need 'em. 2006-08-25 17:09:55 +00:00
Eelco Dolstra
215ec2ddc6 * New primop __toXML (or builtins.toXML) to convert an expression to
an XML representation stored in a string.  This should be useful to
  pass structured information to builders.

Eelco Dolstra
9638f3f393 * Pass the autoArgs to findAlongAttrPath so that "nix-instantiate
foo.nix -A attr --arg name value" will work if (name, value) is
  needed in the evaluation leading up to "attr".

38f18aa6d4 * New primop: abort "error message". 2006-08-23 15:46:00 +00:00
Eelco Dolstra
4a053bfdfd * A new primop `builtins', which returns an attribute set containing
all the primops.  This allows Nix expressions to test for new
  primops and take appropriate action if they're not available.  For
  instance, rather than calling a primop `foo' directly, they could
  say `if builtins ? foo then builtins.foo ... else ...'.

4661282fde * `nix-instantiate ... --arg NAME VALUE': allow arguments to be passed
to functions from the command line.
* nix-build: started removing backticks.

Eelco Dolstra
c11839d7b2 * `nix-instantiate --print-args': print out the valid values for
functions arguments that have a domain.
2006-07-28 14:01:29 +00:00
Eelco Dolstra
ca2238cf81 * Refactoring: get the selection path stuff out of getDerivations()
and put it into a separate function findAlongAttrPath().
2006-07-26 15:05:15 +00:00
Eelco Dolstra
2317d8f671 * `nix-instantiate --print-args' prints out the arguments of a
top-level function.

0e6dc72a7a * Applied rbroek's patch from the branch at
https://svn.cs.uu.nl:12443/repos/trace/buildfarm-control/trunk/ext/nix/,
  with some modifications.  This allows `nix-env -qa' to show the
  attribute path that can be used to unambiguously install a package
  using `nix-env -i -A'.  Example:

    $ nix-env -f top-level/all-packages.nix -qaA subversion xorg-server
    subversionWithJava  subversion-1.2.3
    subversion          subversion-1.3.2
    subversion14        subversion-1.4.0pre-rc1
    xorg.xorgserver     xorg-server-1.1.0

7a3a5d1608 * When there is a domain check, we have to evaluate the argument.
Can't be lazy!
2006-07-24 16:49:28 +00:00
Eelco Dolstra
f4c5531d92 * New language feature: domain checks, which check whether a function
argument has a valid value, i.e., is in a certain domain.  E.g.,

    { foo : [true false]
    , bar : ["a" "b" "c"]
    }: ...

  This previously could be done using assertions, but domain checks
  will allow the buildfarm to automatically extract the configuration
  space from functions.
