Eelco Dolstra ed09821859 * Use atdiff' instead of cmp' for checking test output.

 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.
 2004-10-27 12:41:53 +00:00
Eelco Dolstra f09618b63a * Turn on read-only mode in queries. This prevents redundant store I/O. 2004-10-27 10:24:44 +00:00
Eelco Dolstra c7bea941b0 * Oops, I did it again. 2004-10-27 10:05:51 +00:00
Eelco Dolstra 210ab0296d * Add file to `make dist'. 2004-10-27 00:02:31 +00:00
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.
 2004-10-25 16:54:56 +00:00
Eelco Dolstra f4d44a0026 * Allow certain operations to succeed even if we don't have write 
permission to the Nix store or database.  E.g., `nix-env -qa' will
  work, but `nix-env -qas' won't (the latter needs DB access).  The
  option `--readonly-mode' forces this mode; otherwise, it's only
  activated when the database cannot be opened.
 2004-10-25 14:38:23 +00:00
Eelco Dolstra 3ade3e7721 * Revert r1594 - it didn't solve the problem. Instead add 
svn-revision to distributions, which should fix it.
 2004-10-25 13:51:34 +00:00
Eelco Dolstra 2248becfd3 * Make sure that the prerelease version is included in `--version'. 2004-10-25 12:15:50 +00:00
Eelco Dolstra 50b9caac14 * Updated NEWS for the upcoming 0.6 release. 2004-10-21 09:22:16 +00:00
Eelco Dolstra 2155c0a673 * Register channels as roots of the garbage collector (in 
$(localstatedir)/nix/gcroots/channels). 
* In setuid installations, create gcroots/tmp and gcroots/channels
  group-writable.
 2004-10-20 14:42:38 +00:00
Eelco Dolstra 88888160d2 * Fix nix-prefetch-url in setuid Nix installations. 2004-10-20 14:40:54 +00:00
Eelco Dolstra 99da51d4de * Show error messages from curl. 2004-10-20 14:05:48 +00:00
Eelco Dolstra 2cd590d96c * Instead of — use the actual Unicode character. By the way, to 
edit the manual, you should have something like

    (modify-coding-system-alist 'file "\\.xml\\>" 'utf-8)

  in your ~/.emacs.
 2004-10-18 12:22:14 +00:00
Eelco Dolstra 692204e0c5 * Rewrite of package management stuff. 2004-10-14 16:43:09 +00:00
Eelco Dolstra d830b2c1df * In `nix-env -q', sort derivations by name *without* case 
sensitivity.
 2004-10-14 15:09:55 +00:00
Eelco Dolstra febd8bed1b * Split overview chapter into a chapter on package management and a 
chapter on writing Nix expressions.
 2004-10-14 11:55:12 +00:00
Eelco Dolstra 98c69e5172 * Unindent. 2004-10-14 11:54:41 +00:00
Eelco Dolstra 371c57d8a7 * Updated the quick start section. Use channels instead of 
downloading Nix expressions and calling nix-pull.  This is so
  user-friendly that even a Mac user can do it! :-)
 2004-10-13 15:35:47 +00:00
Eelco Dolstra 2b20701f78 * Better introduction. 
* Set notes in a different color than warnings.
 2004-10-13 15:08:35 +00:00
Eelco Dolstra 1317242780 * Make store objects created by substitutes read-only. 2004-09-22 12:15:04 +00:00
Niels Janssen 995d08208e * prevent collision on log directory 2004-09-19 15:53:37 +00:00
Eelco Dolstra b357284a32 * Fallback didn't work for subderivations of an unnormalised the main 
derivation, since NormalisationGoal would first run a
  NormalisationGoal on the subderivation (a no-op, since in a
  situation where we need fallback the successor is known), and then
  runs a RealisationGoal on the normal form, which then cannot do a
  fallback because it doesn't know the derivation expression for which
  it is a normal form.

  Tossed out the 2-phase normalisation/realisation in
  NormalisationGoal and SubstitutionGoal since it's no longer needed -
  a RealisationGoal will run a NormalisationGoal if necessary.
