Comma: the laconic Nix toolkit
,
runs software without installing it.
,i
installs that software to your nix-env
profile.
,q
has a suite of subcommands for interacting with the Nix Store:
,ql <regex> : (list nix-store entries matching regex)
,qs <store-path*> : nix show-derivation
,qo <store-path*> : nix-store --query --outputs
,qd <store-path*> : nix-store --query --deriver
,q- <store-path*> : nix-store --query --references
,q-- <store-path*> : nix-store --query --requisites
,q+ <store-path*> : nix-store --query --referers
,q++ <store-path*> : nix-store --query --referers-closure
,qx <store-path*> : nix-store --realise
Anything taking <store-path*> can also be called like:
echo <store-path*> | ,q-
Basically it just wraps together nix run
and nix-index
. You stick a ,
in front of a command to
run it from whatever location it happens to occupy in nixpkgs
without really thinking about it.
Installation
nix-env -i -f .

,q
Usage
,q-- ~/.nix-profile | grep ruby | ,qd | ,qo | grep devdoc | ,qx
This is equivalent to something like:
rubies=$(nix-store -qR ~/.nix-profile | grep ruby)
docs=$(nix-store -q --outputs $(nix-store -qd $rubies) | grep devdoc)
nix-store --realise $docs
