Eelco Dolstra cfd20debfb Fix bashrc regression
Interactive non-login shells should not source /etc/profile, otherwise
environment variables set by the user will get clobbered.  For
example:

  $ export PERL5LIB=/foo
  $ bash
  $ echo $PERL5LIB
  /home/eelco/.nix-profile/lib/perl5/site_perl:/nix/var/nix/profiles/default/lib/perl5/site_perl:/run/current-system/sw/lib/perl5/site_perl:/home/eelco/.nix-profile/lib/perl5/site_perl:/nix/var/nix/profiles/default/lib/perl5/site_perl:/run/current-system/sw/lib/perl5/site_perl

Eelco Dolstra b933b15d72 Don't generate /etc/environment
/etc/environment, if it exists, should be a list of NAME=VALUE pairs,
not a shell script.  See the pam_env manpage.

Jan Malakhovski b3f4040512 Radically change the way NixOS handles environment variables and make it possible not to use Bash as the default interactive shell.
This change does two things:

* "NixOSizes" environment variables generation. This allows some more
  error-checking and opens possibilities for a modular environment
  configuration. From now on the most of environment variables are
  generated directly by the nix code. Generating sh code that
  generates environment variables is left in a few places where
  nontrivial access to a local environment state is needed.
* By doing the first change this patch untangles bash from the
  environment configuration and makes it trivial to add a support for
  other non bash-compatible shells.

Now to the sad part. This change is quite large (and I'm not sure it's
possible to split it) and yet is not quite complete, it needs some
changes to nixpkgs to be perfect.
See !!! comments in modules/config/shells-environment.nix.

Main principle behind this change is "change environment generation
and nothing else". In particular, shell configuration principles stay
exactly the same as before.

Eelco Dolstra 17457297cb Update all legacy-style modules
I.e., modules that use "require = [options]".  Nowadays that should be
written as

  {
    options = { ... };
    config = { ... };
  };

Also, use "imports" instead of "require" in places where we actually
import another module.

Marc Weber 2fcd1195e6 bash: change shell script option types from string to lines
installation-cd-base: export mountPoint=/mnt. This doesn't change the default behavior, but an explicit
mount point specification is cleaner.

Eelco Dolstra 24a44c98d2 bash: Disable hashing of command lookups in interactive shells
This just confuses people when (say) using multiple profiles.
Performance benefits for interactive shells are likely to be very
small anyway.

Eelco Dolstra b89f941b20 Provide missing command suggestions, Ubuntu style
If the user tries to run a program that doesn't exist from Bash, the
program name is looked up in a database that maps to Nix package
names.  If it is found, we print out a message like:

  $ pdflatex
  The program ‘pdflatex’ is currently not installed. It is provided by
  several packages. You can install it by typing one of the following:
    nix-env -i tetex
    nix-env -i texlive-core

If the environment variable $NIX_AUTO_INSTALL is set, the command is
installed and executed automatically:

  $ hello --version
  The program ‘hello’ is currently not installed. It is provided by
  the package ‘hello’, which I will now install for you.
  installing `hello-2.8'
  hello (GNU hello) 2.8
  Copyright (C) 2011 Free Software Foundation, Inc. ...

To use this, you must currently manually put the SQLite programs
database in /var/lib/nixos/programs.sqlite.  In the future, this file
should be provided as part of the NixOS channel so it gets updated
automatically.  To get a test version:

  $ curl http://nixos.org/~eelco/programs.sqlite.xz | xz -d > /var/lib/nixos/programs.sqlite

Rob Vermaas 88a9d7a9ca Added environment.promptInit to allow PS1 overriding. Would be nicer to be able to allow overriding via shellInit, however could not get that to work. For now this is a temporary solution which will not break anything. 2012-10-30 13:33:37 +01:00

Peter Simons efc104c4c8 modules/programs/bash: improve bash completion support
The new configuration.nix option 'environment.enableBashCompletion'
determines whether bash completion is automatically enabled system-wide
for all interactive shells or not. The default setting is 'off'.

Eelco Dolstra 6f03065dce * Move the setting of $MODULE_DIR to modprobe.nix.
* Add a slash to the end of $MODULE_DIR, as expected by depmod.  (Not
  that running depmod from the command line is all that useful, since
  you can't use it to update the tree in the Nix store.  But at least
  commands like "depmod -n" work now.)  Reported by Kirill Elagin on
  IRC.

Eelco Dolstra e97817b577 * Atomically replace the /bin/sh symlink; otherwise there is a time
window in which /bin/sh is missing.  This can cause concurrently
  running programs to fail (e.g. Hydra jobs =>
  http://hydra.nixos.org/build/2267831).  You'd think the odds of this
  are very low, but they're not.

Florian Friesdorf eb755d4692 switched all mergeOptionString to pkgs.lib.types.string
pierron recommended the use of types.string over mergeOptionString, as
it is superior but might break things.

For my system the change evaluated to the exactly same.

Peter Simons 432d71f3ed modules/programs/bash: major clean-up and re-factoring of /etc/profile and /etc/bashrc
* Moved bash-specific code from /etc/profile to /etc/bashrc.

 * Moved general Bourne shell code from /etc/bashrc to /etc/profile.

 * Added "include guards" to both files to ensure that they aren't sourced
   multiple times (which would result in lots of redundancy in $PATH, etc.).

 * Both files include each other to make sure that the correct system
   environment is always defined.

 * When the current user has installed the 'bash-completion' package in her
   $HOME/.nix-profile, programmable completion is automatically enabled in
   interactive shells.

 * The /etc/skel/.bashrc we installed has been dropped because it is redundant.

Eelco Dolstra f729f12e4e Some cleanups in the activation script:
* Moved some scriptlets to the appropriate modules.
* Put the scriptlet that sets the default path at the start, since it
  never makes sense not to have it there.  It no longer needs to be
  declared as a dependency.
* If a scriptlet has no dependencies, it can be denoted as a plain
  string (i.e., `noDepEntry' is not needed anymore).
