The indentation stripping semantics of strings are fairly bad and have a few gotchas where the resulting string has not the intended indentation. This commit fixes most if not all such instances in Nixpkgs. I tried to strive a balance between keeping the diff small and reformatting/refactoring the code to look better. In general, reformatting should be left to Nixfmt. Note that this causes a lot of rebuilds by design. All changes need to be thoroughly vetted and reviewed for correctness. There is no automatic way to prove correctness. List of files to fix generated by running https://gerrit.lix.systems/c/lix/+/2092 on Nixpkgs and looking at the warnings.

|
|
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.
