A modern, delicious implementation of the Nix package manager, focused on correctness, usability, and growth — and committed to doing right by its community
When generating shell completions, no logging output should be visible because
it would destroy the shell prompt. Originally this was attempted to be done by
simply disabling the progress bar (ca946860ce),
since the situation is particularly bad there (the screen clearing required for
the rendering ends up erasing the shell prompt). Due to overlooking the
implementation of this hack, it was accidentally undone during a later change
(0dd1d8ca1c).
Since even with the hack correctly in place, it is still possible to mess up
the prompt by logging output (for example warnings for disabled experimental
features, or messages generated by `builtins.trace`), simply send it to the bit
bucket where it belongs. This was already done for bash and zsh
(9d840758a8), and it seems that fish was simply
missed at that time. The last trace of the no-longer-working and obsolete hack
is deleted too.
