# this is the example we will be using
nixEnv = simple {
name = "nix";
buildInputs = [ libtool stdenv perl curl bzip2 openssl aterm242fixes db45 autoconf automake zlib ];
cTags = [ aterm242fixes];
name = "mytestenv";

# this is a second example (not covered here but still useful) - given by viric
sdlEnv = pkgs.myEnvFun {
name = "sdl";
buildInputs = [ stdenv SDL SDL_image SDL_ttf SDL_gfx cmake SDL_net pkgconfig];
};
# add more environments below here, just follow the syntax given in the above examples
};
}
Put this into your .bashrc
put this into your .bashrc
loadEnv(){ . "${HOME}/.nix-profile/dev-envs/${1}"; }
then nix-env -iA env-nix
and
$ loadEnv postgresql
afterwards execute the new bash shell:
$ bash
the nix expression created is called: env-mytestenv and must appear when searching for it using:
$ nix-env -qa '*' | grep nix
env-mytestenv
now we should build our newly defined custom environment using this command on a shell, so type:
$ nix-env -iA env-mytestenv
afterwards load the new environment using:
$ loadEnv mytestenv
one could also use this function instead:
$ load-mytestenv-env
the result using either command should be:
env-mytestenv loaded
note: after you typed the above command you will lose all the other tools usually found in a shell you are used to. in this
example you will not be able to type 'vi' to edit a file as vi is not included in the dependencies
