Eelco Dolstra b2235d81d1 * Restore the __overrides feature that was lost somewhere in the 
fast-eval branch.
 2010-05-15 08:10:12 +00:00
Eelco Dolstra bd25ac2260 * Print attributes in sorted order. 2010-05-12 12:15:49 +00:00
Eelco Dolstra 81a4b4e49b * Implemented tryEval, the last missing primop in the fast-eval 
branch.  Also added a test for tryEval.

Eelco Dolstra 1a8eb6e3ec 2010-05-07 15:26:33 +00:00
Eelco Dolstra 83dfa89870 * Sync with the trunk. 2010-05-07 14:46:47 +00:00
Eelco Dolstra 01e58adce0 * Store position info for inherited attributes. 2010-05-07 12:43:57 +00:00
Eelco Dolstra 83d7b89660 * Updated addErrorContext. 2010-05-07 12:33:14 +00:00
Eelco Dolstra e2d5e40f4f * Keep track of the source positions of attributes. 2010-05-07 12:11:05 +00:00
Eelco Dolstra 84ce7ac76f * Store attribute positions in the AST and report duplicate attribute 
errors with position info.
* For all positions, use the position of the first character of the
  first token, rather than the last character of the first token plus
  one.

Eelco Dolstra c82782f9a5 2010-04-27 09:05:11 +00:00
Eelco Dolstra 2be6118f4c * Don't need the test program anymore. 2010-04-23 09:09:32 +00:00
Eelco Dolstra 0bc468f195 * Simplify the implementation of `with'. This gives a 7% speedup in 
evaluating the NixOS system configuration.
 2010-04-22 15:08:09 +00:00
Eelco Dolstra ebade9ff8b * Check for duplicate attribute names / function arguments. `make 
check' now succeeds :-)
* An attribute set such as `{ foo = { enable = true; };
  foo.port = 23; }' now parses.  It was previously rejected, but I'm
  too lazy to implement the check.  (The only reason to reject it is
  that the reverse, `{ foo.port = 23; foo = { enable = true; }; }', is
  rejected, which is kind of ugly.)
 2010-04-22 11:02:24 +00:00
Eelco Dolstra 2d7636529f * String equality tests should take the context into account. All the 
evaluation test cases now succeed.
 2010-04-22 09:54:11 +00:00
Eelco Dolstra 6bbfe95e30 * Don't use an ostringstream in unparseDerivation(), because it's 
slow.  A `nix-env -qa --drv-path \*' on Nixpkgs was spending 40% of
  its time in unparseDerivation() because of this (now 11%).
 2010-04-21 19:25:50 +00:00
Eelco Dolstra 6f0f16497a * Fix the interpretation of ''\<character> in indented strings. 2010-04-21 16:18:27 +00:00
Eelco Dolstra 0777448ca6 * Fixed builtins.genericClosure. 2010-04-21 15:57:11 +00:00
Eelco Dolstra fe2d869e04 * Store user environment manifests as a Nix expression in 
$out/manifest.nix rather than as an ATerm.

  (Hm, I thought I committed this two days ago...)
 2010-04-21 15:08:58 +00:00
Eelco Dolstra f3b8833a48 * Drop the dependency on the ATerm library. 2010-04-19 14:51:58 +00:00
Eelco Dolstra efc7a579e8 * Don't use the ATerm library for parsing/printing .drv files. 2010-04-19 13:46:58 +00:00
Eelco Dolstra 55b5ddd3ca * Added parsing of manifests in ATerm format. 2010-04-19 12:10:04 +00:00
Eelco Dolstra b7ff69eb7c * Refactoring: move the user environment stuff into its own module. 2010-04-19 10:47:56 +00:00
Eelco Dolstra 5c31995bb8 * Updated some more primops. 2010-04-16 15:13:47 +00:00
Eelco Dolstra 8bb0210fea * _combineChannels shouldn't be an integer. 2010-04-16 14:07:52 +00:00
Eelco Dolstra 8ca4a001cb * Improve sharing a bit. 2010-04-16 14:03:26 +00:00
Eelco Dolstra 497e4ad126 * Remove some redundant tests. 2010-04-16 13:51:01 +00:00
Eelco Dolstra 02c1dac909 * In an nested with' where the inner with is a variable (with ...; 
with someVar; ...'), the contents of the variable would be
  clobbered.  (The attributes in the outer `with' were added to the
  variable.)
 2010-04-16 13:44:02 +00:00
Eelco Dolstra 04c4bd3624 * Store lists as lists of pointers to values rather than as lists of 
values.  This improves sharing and gives another speed up.
  Evaluation of the NixOS system attribute is now almost 7 times
  faster than the old evaluator.
 2010-04-15 00:37:36 +00:00
Eelco Dolstra e41b5828db * Better stats. 2010-04-14 23:48:46 +00:00
Eelco Dolstra d39d3c6264 * Implemented inherit. 2010-04-14 23:25:05 +00:00
Eelco Dolstra 267dc693d2 * Fix builtins. 2010-04-14 22:59:39 +00:00
Eelco Dolstra 81de12bc8f * Refactoring: move variable uses to a separate class. 2010-04-14 15:14:23 +00:00
Eelco Dolstra 110d155778 * Implemented withs. 2010-04-14 15:01:04 +00:00
Eelco Dolstra 9985230c00 * After parsing, compute level/displacement pairs for each variable 
use site, allowing environments to be stores as vectors of values
  rather than maps.  This should speed up evaluation and reduce the
  number of allocations.
 2010-04-14 14:42:32 +00:00
Eelco Dolstra 816dd3f061 * Remove more obsolete code. 2010-04-14 12:49:05 +00:00
Eelco Dolstra 011b5da0f4 * Get nix-env to compile again. 2010-04-14 09:39:06 +00:00
Eelco Dolstra 85d13c8f93 * Change the semantics of "with" so that inner "withs" take 
precedence, i.e. `with {x=1;}; with {x=2;}; x' evaluates to 2'.
  This has a simpler implementation and seems more natural.  There
  doesn't seem to be any code in Nixpkgs or NixOS that relies on the
  old behaviour.
 2010-04-14 08:37:08 +00:00
Eelco Dolstra 816f9c0f6f * Use std::tr1::unordered_set instead of std::set for the symbol 
table.  This gives a 10% speed increase on `nix-instantiate
  /etc/nixos/nixos -A system --readonly-mode'.
 2010-04-13 14:34:11 +00:00
Eelco Dolstra 7d47498b5e * Evaluate lets directly (i.e. without desugaring to `rec { attrs...; 
<let-body> = e; }.<let-body>).  This prevents the unnecessary
  allocation of an attribute set.
 2010-04-13 13:42:25 +00:00
Eelco Dolstra ac1e8f40d4 * Use a symbol table to represent identifiers and attribute names 
efficiently.  The symbol table ensures that there is only one copy
  of each symbol, thus allowing symbols to be compared efficiently
  using a pointer equality test.
 2010-04-13 12:25:42 +00:00
Eelco Dolstra 10e8b1fd15 * Finished the ATerm-less parser. 2010-04-12 23:33:23 +00:00
Eelco Dolstra 0d272fca79 * Remove some obsolete functions. 2010-04-12 23:31:47 +00:00
Eelco Dolstra d4f0b0fc6c * Indented strings. 2010-04-12 22:03:27 +00:00
Eelco Dolstra a60317f20f * More missing constructs. 2010-04-12 21:21:24 +00:00
Eelco Dolstra 4d6ad5be17 * Don't use ATerms for the abstract syntax trees anymore. Not 
finished yet.
 2010-04-12 18:30:11 +00:00
Eelco Dolstra ed711f73bc * Don't use ATerms to represent integers in the lexer. 2010-04-12 10:38:18 +00:00
Eelco Dolstra db90b88e65 * Hack to support builderDefs expressions. 2010-04-12 09:50:20 +00:00
Eelco Dolstra 4e49002576 * Doh. 2010-04-12 09:45:00 +00:00

Ludovic Courtès aac5fcfbb5 Re-add drvPath' and outPath' attributes to <derivation> XML nodes. 
This fixes a regression introduced in r20882 ("Add source location
information to the XML output.").

* src/libexpr/expr-to-xml.cc (nix::printTermAsXML): Dereference the
  attribute RHS from "drvPath" and "outPath".
