Before this patch, installing Nix using the Fish shell did not
work because Fish wasn't configured to add Nix to the PATH. Some
options in #1512 offered workarounds, but they typically involve
extra plugins or packages.
This patch adds native, out-of-the-box support for the Fish shell.
Note that Fish supports a `conf.d` directory, which is intended
for exactly use cases like this: software projects distributing
shell snippets. This patch takes advantage of it. The installer
doesn't append any Nix loader behavior to any Fish config file.
Because of that, the uninstall process is smooth and a reinstall
obliterates the existing nix.fish files that we place instead of
bothering the user with a backup / manual removal.
Both single-user and multi-user cases are covered. It has been
tested on Ubuntu, and a Mac with MacPorts, homebrew, and the
Fish installer pkg.
Closes #1512

While trying to figure out how `nix-env`/`nix profile` work I had a hard
time understand how man pages were being installed.
Took me quite some time to figure this out, thought it might be useful
to others too!

|
|
This is not used anywhere.
|
|
|

This is already done by the installer, so no need to do it again.

'nix-daemon' now creates subdirectories for users when they first
connect.
Fixes #509 (CVE-2019-17365).
Should also fix #3127.

When we are in single user mode, we still want to have access to
profiles. This way things in Nixpkgs that rely on them getting set
accurately are done in both cases. The point where I hit this is with
using aspell which looks in NIX_PROFILES:
https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/aspell/default.nix
Before this patch, NIX_PROFILES was never set in single user mode!
This corrects that.

Fixes #2709.

Checking for MANPATH without quotes always returns true, so that it breaks bash-completion for man pages on modern systems without MANPATH environment variable.
|
|
This does not belong in Nix. Setting this env var is already done by the aspell derivation found in Nixpkgs.

sbin is a symlink to bin.
profiles only contains packages, which have this symlink.
It is a subset of bin.

This prevents collisions with the "native" OpenSSL, in particular on
OS X.
Fixes #921.

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.

Use the same logic as NixOS' profile and environment setup. Closes #414
|

All other places in the script do this already, so let's be consistent.

This reverts commit 76f985b92d95fef967c1f3193d05244ced15420b. We
shouldn't mess with $MANPATH, because on some "man" implementations
(like NixOS'), the default value on $MANPATH is derived from $PATH. So
if you set $MANPATH, you lose the default locations.

Commit 6a214f3e06fa1c5f0a4d40e555f14d87691af297 copied most of the Nix
shell initialisation code from NixOS to nix-profile.sh; however, that
code assumes a multi-user install and is Linux-specific (e.g. it calls
the "stat" command). So go back to the simple single-user version.
Fixes #49.

Commit 6a214f3e06fa1c5f0a4d40e555f14d87691af297 reused the NixOS
environment initialisation for nix-profile.sh, but this is
inappropriate on systems that don't have multi-user support enabled.

usable by normal users - install as a data file, not a program file

It's no longer needed because Nixpkgs' fontconfig uses
/etc/fonts/fonts.conf as a default, just like other distributions.

the symlink ~/.nix-userenv to the given argument (which defaults to
.../links/current). /etc/profile.d/nix-profile creates this symlink
if it doesn't exist yet. Example use:
$ nix-env -l my_profile -i foo.nix subversion quake
$ nix-env -p my_profile
I don't like the term "profile". Let's deprecate it :-)

dynamically links against libdb4 (?!), due to LD_LIBRARY_PATH it picks
up our libdb4 instead of SuSE's libdb4, but our libdb4 uses another
glibc so loading barfs.
Instead, all packages should use rpaths to store library locations in
executables/libraries. The disadvantage is that overriding rpaths is
harder. (It is possible by invoking the dynamic linker directly, e.g.,
`/lib/ld-linux.so.2 --ignore-path LIST program args...' to ignore the
rpath for the libraries in LIST). It would be better to use DT_RUNPATH,
which is consulted by the dynamic linker *after* LD_LIBRARY_PATH but
*before* ld.so.cache and the system directories.

etc. correctly.
* Fixed nix-switch.
