Revert "Get rid of unicode quotes ()"
This reverts commit f78126bfd6. There
really is no need for such a massive change...

Manav Rathi eec5409a69 installation: allow profile modification to be skipped ()
The current behaviour modifies the first writeable file from amongst
.bash_profile, .bash_login and .profile.  So .bash_profile (if it is
writable) would be modified even if a user has already sourced nix.sh
in, say, .profile.

This commit introduces a new environment variable,
NIX_INSTALLER_NO_MODIFY_PROFILE.  If this is set during installation,
then the modifications are unconditionally skipped.

This is useful for users who have a manually curated set of dotfiles
that they are porting to a new machine. In such scenarios, nix.sh is
already sourced at a place where the user prefers.  Without this
change, the nix installer would insist on modifying .bash_profile if
it exists.

This commit also add documentations for both the current behaviour and
the new override.

Alexey Shmalko eef754813f Set $MANPATH ()
Currently, man has issues finding man pages for Nix-installed
application (also, `nix-env --help` doesn't work). The issue is caused
by custom `$MANPATH` set by my system. That makes man use it instead of
searching in default location.

Either of next lines workaround the issue:
```sh
unset MANPATH

export MANPATH=$HOME/.nix-profile/share/man:$MANPATH
```

This patch adds the later line to the `nix-profile.sh` if user has
`MANPATH` set. (Not clearing `MANPATH` as that would be disrespect of
user's preferences.)

As a side-effect, host's man might find man pages installed by Nix.

Eelco Dolstra 4494000e04 LocalStore: Allow the physical and logical store directories to differ
This is primarily to subsume the functionality of the
copy-from-other-stores substituter. For example, in the NixOS
installer, we can now do (assuming we're in the target chroot, and the
Nix store of the installation CD is bind-mounted on /tmp/nix):

  $ nix-build ... --option substituters 'local?state=/tmp/nix/var&real=/tmp/nix/store'

However, unlike copy-from-other-stores, this also allows write access
to such a store. One application might be fetching substitutes for
/nix/store in a situation where the user doesn't have sufficient
privileges to create /nix, e.g.:

  $ NIX_REMOTE="local?state=/home/alice/nix/var&real=/home/alice/nix/store" nix-build ...

Gabriel Gonzalez 3889415bf8 Fix ?? in Nix warning message
Nix sometimes outputs a warning message like this:

```
directory /nix does not exist; creating it by running ‘?? using sudo
```

... when it really meant to output something that looked like this:

```
directory /nix does not exist; creating it by running 'mkdir -m 0755 /nix && chown gabriel /nix' using sudo
```

The reason why is due to some bizarre behavior in Bash where it will translate anything of the form `$x’` to `??`, leading to the incorrect warning message.  I don't know what is the origin of this Bash behavior, but the easiest fix is to just use ASCII quotes instead of unicode quotes.

wmertens 4916d92092 Always verify nix store on install
Just wasted a couple hours chasing shadows because the nix store got

Since an install is one-time only, might as well verify.  Optimization
showed that the copied files aren't read-only; fixed that as well.

Also, use /bin/sh since there's a good chance that this script will be
run on systems without /bin/bash

Philip Potter 4f3cf06c97 Verify TLS certificate before downloading binaries
The --insecure flag to curl tells curl not to bother checking if the TLS
certificate presented by the server actually matches the hostname
requested, and actually is issued by a trusted CA chain.  This almost
entirely negates any benefit from using TLS in the first place.

This removes the --insecure flag to ensure we actually have a secure
connection to the intended hostname before downloading binaries.

Manually tested locally within a dev-shell; was able to download
binaries from https://cache.nixos.org without issue.

[Note: --insecure was only used for fetching NARs, whose integrity is
verified by Nix anyway using the hash from the .narinfo. But if we can
fetch the .narinfo without --insecure, we can also fetch the .nar, so
there is not much point to using --insecure. --Eelco]

Eelco Dolstra f3a5930488 Sign a subset of the .narinfo
We only need to sign the store path, NAR hash and references (the
"fingerprint"). Everything else is irrelevant to security. For
instance, the compression algorithm or the hash of the compressed NAR
don't matter as long as the contents of the uncompressed NAR are
correct.

(Maybe we should include derivers in the fingerprint, but they're
broken and nobody cares about them. Also, it might be nice in the
future if .narinfos contained signatures from multiple independent
signers. But that's impossible if the deriver is included in the
fingerprint, since everybody will tend to have a different deriver for
the same store path.)

Also renamed the "Signature" field to "Sig" since the format changed
in an incompatible way.

‘--run’ is like ‘--command’, except that it runs the command in a

Hitting Ctrl-C while make is running drops you into the interactive

instead.

Eelco Dolstra a957893b26 Allow nix-shell to be used as a #! interpreter
This allows scripts to fetch their own dependencies via nix-shell. For
instance, here is a Haskell script that, when executed, pulls in GHC
and the HTTP package:

  #! /usr/bin/env nix-shell
  #! nix-shell -i runghc -p haskellPackages.ghc haskellPackages.HTTP

  import Network.HTTP

  main = do
    resp <- Network.HTTP.simpleHTTP (getRequest "http://nixos.org/")
    body <- getResponseBody resp
    print (take 100 body)

Or a Perl script that pulls in Perl and some CPAN packages:

  #! /usr/bin/env nix-shell
  #! nix-shell -i perl -p perl perlPackages.HTMLTokeParserSimple perlPackages.LWP

  use HTML::TokeParser::Simple;

  my $p = HTML::TokeParser::Simple->new(url => 'http://nixos.org/');

  while (my $token = $p->get_tag("a")) {
      my $href = $token->get_attr("href");
      print "$href\n" if $href;
  }

Note that the options to nix-shell must be given on a separate line
that starts with the magic string ‘#! nix-shell’. This is because
‘env’ does not allow passing arguments to an interpreter directly.
