Hi,
`nix-env -i $(nix-build -A fzf.out)` works.
Somehow, `nix-env -f . -iA fzf.out` still installs `fzf.bin`.
Now, that package is quite strange. Normally, the first output in the
outputs list should be the one that refers to all the others.
It is not the case here, because fzf.bin does not reference fzf.out for
example.
Also, it could specify outputsToInstall, but it does not.
See http://nixos.org/nixpkgs/manual/#idm140737318250400 and related
issues to dig deeper into this.
But please keep in mind that nix received only maintenance update since
Jan 19, 2016.
A lot of merged features are not available in any release.
-- Layus.

I've tried with fzf.out and it also doesn't add anything to 'share' in
profile folder. The only way I was able to make it work is by adding
'share' folder to 'bin' output. Looks like some magic is attached to
'bin' itself (because I've also tried reordering outputs without any
change) - but I can't figure out how and why this is happening.
1) For fzf.out 'vim-plugins' folder is not added to profile after installation
$ nix-build . -A fzf.out
/nix/store/mp5drsp2l1z7k0rp4jjmll06kjck7052-fzf-0.16.6
# 'share' is present in nix store
$ ls ./result/share/vim-plugins/ -l
total 4
lrwxrwxrwx 1 root root 91 Jan 1 1970 fzf-0.16.6 ->
/nix/store/mp5drsp2l1z7k0rp4jjmll06kjck7052-fzf-0.16.6/share/go/src/github.com/junegunn/fzf
$ nix-env -f . -iA fzf.out
# But it's missing from profile even after explicitly installing that
$ ls -la ~/.nix-profile/share/vim-plugins
ls: cannot access '/home/binarin/.nix-profile/share/vim-plugins': No such
file or directory
2) But everything works if I add 'share' folder to 'bin' output instead, using
the following
lines in postInstall:
+ mkdir -p $bin/share/vim-plugins
+ cp -a $out/share/go/src/github.com/junegunn/fzf $bin/share/fzf-tmp
+ ln -s $bin/share/fzf-tmp $bin/share/vim-plugins/${name}
$ nix-build . -A fzf.bin
/nix/store/3dzqj1xk6s5jfm1z4kwnkfdg9yw3xckr-fzf-0.16.6-bin
$ ls ./result-bin/share/vim-plugins/ -l
total 4
lrwxrwxrwx 1 root root 72 Jan 1 1970 fzf-0.16.6 ->
/nix/store/3dzqj1xk6s5jfm1z4kwnkfdg9yw3xckr-fzf-0.16.6-bin/share/fzf-tmp
$ nix-env -f . -iA fzf.bin
$ ls -la ~/.nix-profile/share/vim-plugins
lrwxrwxrwx 1 root root 76 Jan 1 1970
/home/binarin/.nix-profile/share/vim-plugins ->

Best,

I guess the idea is that you need to install `fzf.out` explicitly,
because installing `fzf` installs the first output, which is `fzf.bin`.

Hi folks.
What are the rules about how and when 'share/' folder of (multi-output)
derivation will be merged into 'share/' folder of profile?
E.g. I can't see content of
https://github.com/NixOS/nixpkgs/blob/4a0be7837cadf9b6e9cae430d80f65a2af60dcc6/pkgs/tools/misc/fzf/default.nix#L33
anywhere in my profile 'share/' even after installing every output
Only when I move 'share/' to '$bin' output, it starts appearing in profile
'share/' folder.
Best,
Alexey
