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

'' GNU Parallel is a shell tool for executing jobs in parallel. A job
|
|
is typically a single command or a small script that has to be run
|
|
for each of the lines in the input. The typical input is a list of
|
|
files, a list of hosts, a list of users, or a list of tables.
|
|
|
|
If you use xargs today you will find GNU Parallel very easy to use.
|
|
If you write loops in shell, you will find GNU Parallel may be able
|
|
to replace most of the loops and make them run faster by running
|
|
jobs in parallel. If you use ppss or pexec you will find GNU
|
|
Parallel will often make the command easier to read.
|
|
|
|
GNU Parallel makes sure output from the commands is the same output
|
|
as you would get had you run the commands sequentially. This makes
|
|
it possible to use output from GNU Parallel as input for other
|
|
programs.
