nix edit - open the Nix expression of a Nix package in $EDITOR
nix edit [option...] installable
Open the Nix expression of the GNU Hello package:
# nix edit nixpkgs#hello
Get the filename and line number used by
# nix eval --raw nixpkgs#hello.meta.position /nix/store/fvafw0gvwayzdan642wrv84pzm5bgpmy-source/pkgs/applications/misc/hello/default.nix:15
This command opens the Nix expression of a derivation in an
editor. The filename and line number of the derivation are taken from
meta.position attribute. Nixpkgs'
this attribute to the location of the definition of the
name derivation attributes.
The editor to invoke is specified by the
variable. It defaults to
cat. If the editor is
kak, it is passed the line number of the derivation using
start an interactive environment if evaluation fails
Common evaluation options:
Pass the value expr as the argument name to Nix functions.
Pass the string string as the argument name to Nix functions.
The Nix store to use for evaluations.
Allow access to mutable paths and repositories.
Add path to the list of locations used to look up
Override the flake registries, redirecting original-ref to resolved-ref.
Common flake-related options:
Commit changes to the flake's lock file.
Use the inputs of the specified flake as registry entries.
Don't allow lookups in the flake registries. This option is deprecated; use
Do not allow any updates to the flake's lock file.
Do not write the flake's newly generated lock file.
Override a specific flake input (e.g.
dwarffs/nixpkgs). This implies
Recreate the flake's lock file from scratch.
Update a specific flake input (ignoring its previous entry in the lock file).
Options that change the interpretation of installables:
Operate on the store derivation rather than its outputs.
Interpret installables as attribute paths relative to the Nix expression expr.
Interpret installables as attribute paths relative to the Nix expression stored in file. If file is the character -, then a Nix expression will be read from standard input. Implies
