treewide: with stdenv.lib; in meta -> with lib; Part of: https://github.com/NixOS/nixpkgs/issues/108938 meta = with stdenv.lib; is a widely used pattern. We want to slowly remove the `stdenv.lib` indirection and encourage people to use `lib` directly. Thus let’s start with the meta field. This used a rewriting script to mostly automatically replace all occurances of this pattern, and add the `lib` argument to the package header if it doesn’t exist yet. The script in its current form is available at https://cs.tvl.fyi/depot@2f807d7f141068d2d60676a89213eaa5353ca6e0/-/blob/users/Profpatsch/nixpkgs-rewriter/default.nix 2021-01-11 08:54:33 +01:00			`{ lib, stdenv, fetchurl, mecab-ipadic }:`
