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

c11839d7b2 * `nix-instantiate --print-args': print out the valid values for 
functions arguments that have a domain.

ca2238cf81 * Refactoring: get the selection path stuff out of getDerivations() 
and put it into a separate function findAlongAttrPath().

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

5744dd5480 * Support the --attr / -A flag in nix-env as well. So now we can do, 
e.g.,

  $ nix-env -i -A subversion xorg.xorgserver

  The main advantage over using symbolic names is that using attribute
  names is unambiguous and much, much faster.

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

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.

a4273156c4 * Use $(libexecdir) to find find-runtime-roots.pl. 2006-07-20 13:21:37 +00:00
Eelco Dolstra
ee2cf45d76 * Use debug(). 2006-07-20 12:19:55 +00:00
Eelco Dolstra
c15f544356 * Call find-runtime-roots.pl from the garbage collector to prevent 
running applications etc. from being garbage collected.

4f3725b167 * Better error messages (especially wrt types). 2006-07-19 15:36:15 +00:00

e10b830251 * Doh! Of couse we cannot memoize across scopes. 2006-07-11 10:29:52 +00:00
Eelco Dolstra
d51aede4af * Allow the canonical system name to be specified at runtime in the 
Nix config file.
 2006-07-06 15:30:37 +00:00

a945fb7905 * `nix-env --upgrade --eq': only upgrade if the old version is equal 
to the new version.  This is actually useful.

dbf6d7e783 * Concurrent GC on Cygwin. 2006-06-20 17:48:10 +00:00

5bb3444032 * _exit() doesn't seem to work right on Cygwin. 2006-06-19 16:24:15 +00:00
Eelco Dolstra
b35735d8b2 * On Windows we cannot delete open (lock) files, so we delete lock 
files after we've closed them.  Since this only succeeds if the lock
  is no longer opened by any process, the token trick used on Unix is
  not necessary.
 2006-06-19 14:43:13 +00:00
Eelco Dolstra
0e783e5579 * Write messages to stderr in a slightly more atomic way. Useful when 
there are several parallel processes.

c937b73622 * Show when we're blocked waiting for a lock. 2006-06-16 10:13:03 +00:00
Eelco Dolstra
588cb0eade * In `nix-env -i|-u|-e', lock the profile to prevent races between 
concurrent nix-env operations on the same profile.  Fixes NIX-7.
 2006-06-15 11:56:49 +00:00

b454977909 * Fix for a problem with BSD's group ownership semantics when the user 
is not in the "wheel" group.

23960e92df * Minor cleanup. 2006-06-01 18:13:33 +00:00
Eelco Dolstra
50fe85f016 * For fixed-output derivations, pass the environment variables listed 
in the attribute variable `impureEnvVars' from the caller to the
  builder.

b5988004d6 * Support for srcdir != builddir (NIX-41). 2006-05-12 11:47:45 +00:00
Eelco Dolstra
9d72bf8835 * 64-bit compatibility fixes (for problems revealed by building on an Athlon 
64 running 64-bit SUSE).  A patched ATerm library is required to run Nix
  succesfully.
 2006-05-11 02:19:43 +00:00

c54287eafe * GCC 2.95 compatibility. 2006-05-08 15:15:13 +00:00
Eelco Dolstra
5cabd47394 * Allow function argument default values to refer to other arguments 
of the function.  Implements NIX-45.

310e605995 * Show evaluation stats when NIX_SHOW_STATS=1. 2006-05-08 10:00:37 +00:00
Eelco Dolstra
0832956089 * Use the new ATermMap. 2006-05-04 12:21:08 +00:00
Eelco Dolstra
d300b4383d * Optimise null-ary term builders. Also declare all term builder 
functions as pure, which might improve performance a bit.
 2006-05-02 21:58:46 +00:00
Eelco Dolstra
68174bdc7d * Use a linked list of substitutions. This reduces the amount of 
copying.
 2006-05-02 21:39:02 +00:00
Eelco Dolstra
c791e94aee * Removed a bunch of ATreverses. 2006-05-02 17:51:50 +00:00
Eelco Dolstra
b52e711910 * Huge reduction in memory use (2/3 or so on large nix-env -qas 
operations): share ATermMaps between DrvInfos.
 2006-05-02 17:12:03 +00:00
Eelco Dolstra
11ae2d1e7a * Memory reduction: replaced expensive calls to ATmakeApplList by 
ATmakeApplArray, and got rid of ATreverse in substitute().

dc719e6ba5 * Some preliminaries towards NIX-45. 2006-05-02 13:39:55 +00:00
Eelco Dolstra
7276e194ee * Disallow unescaped $ in string literals. 2006-05-01 15:29:46 +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.
 2006-05-01 14:01:47 +00:00
Eelco Dolstra
6cecad2be0 * Allow string concatenations involving derivations, e.g., 
configureFlags = "--with-freetype2-library="
      + freetype + "/lib";
 2006-05-01 09:56:56 +00:00
Eelco Dolstra
ef2d4a2da9 * Print a more useful stack trace when an error occurs deep in the 
derivation dependency graph.
 2006-03-24 14:02:44 +00:00
Eelco Dolstra
b69e469328 * In `nix-env', look for derivations inside attribute sets that have 
the `recurseForDerivations' attribute set to `true'.
 2006-03-23 16:43:07 +00:00
Eelco Dolstra
49ce8b57dd * Hm. 2006-03-23 16:37:49 +00:00
Eelco Dolstra
fdea084c36 * Allow `make check' to work in directories that have symlink 
components.

37d1b1cafd * `nix-env -qa --description' shows human-readable descriptions of 
packages (provided that they have a `meta.description' attribute).
  E.g.,

  $ ./src/nix-env/nix-env -qa --description gcc
  gcc-4.0.2   GNU Compiler Collection, 4.0.x (cross-compiler for sparc-linux)
  gcc-4.0.2   GNU Compiler Collection, 4.0.x (cross-compiler for mips-linux)
  gcc-4.0.2   GNU Compiler Collection, 4.0.x (cross-compiler for arm-linux)
  gcc-4.0.2   GNU Compiler Collection, 4.0.x
