that you want to use as the directory for import such as
with (import <nixpkgs> { });
then you can say
$ nix-build -I nixpkgs=/home/eelco/src/stdenv-updates
brackets, e.g.
import <nixpkgs/pkgs/lib>
are resolved by looking them up relative to the elements listed in
the search path. This allows us to get rid of hacks like
import "${builtins.getEnv "NIXPKGS_ALL"}/pkgs/lib"
The search path can be specified through the ‘-I’ command-line flag
and through the colon-separated ‘NIX_PATH’ environment variable,
e.g.,
$ nix-build -I /etc/nixos ...
If a file is not found in the search path, an error message is
lazily thrown.
the hook every time we want to ask whether we can run a remote build
(which can be very often), we now reuse a hook process for answering
those queries until it accepts a build. So if there are N
derivations to be built, at most N hooks will be started.
The /bin/sh interpreter on Solaris doesn't understand $(...) syntax for running
sub-shells. Consequently, this test fails on Solaris. To remedy the situation,
the script either needs to be run by /bin/bash -- which is non-standard --, or
it needs to use the ancient but portable `...` syntax.
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.)
* src/libexpr/expr-to-xml.cc (nix::showAttrs): Add `location'
parameter. Provide location XML attributes when it's true. Update
callers.
(nix::printTermAsXML): Likewise.
* src/libexpr/expr-to-xml.hh (nix::printTermAsXML): Update prototype;
have `location' default to `false'.
* src/nix-instantiate/nix-instantiate.cc (printResult, processExpr): Add
`location' parameter; update callers.
(run): Add support for `--no-location'.
* src/nix-instantiate/help.txt: Update accordingly.
* tests/lang.sh: Invoke `nix-instantiate' with `--no-location' for the
XML tests.
* tests/lang/eval-okay-toxml.exp, tests/lang/eval-okay-to-xml.nix: New
files.
allowed. So `name1@name2', `{attrs1}@{attrs2}' and so on are now no
longer legal. This is no big loss because they were not useful
anyway.
This also changes the output of builtins.toXML for @-patterns
slightly.
