|Get sources for a package | |||
|<pre>apt-get source emacs</pre> | |||
| | |||
|In Debian, apt-get source gets both the patched upstream source and the recipe for the package. Those need two steps in Nix. | |||
To find the package recipe: <pre>grep -r emacs $(nix-instantiate --eval --expr '<nixpkgs>')</pre> | |||
To download the source as specified by the package recipe: <pre>nix-build '<nixpkgs>' -A emacs.src</pre> | |||
The patched source is usually not a derivation itself, but can be produced for most packages with the following command: <pre>nix-shell '<nixpkgs>' -A emacs\ | |||
--command 'unpackPhase; patchPhase'</pre> | |||
