Teach installShellCompletion how to install completions from a named
pipe. Also add a convenience flag `--cmd NAME` that synthesizes the name
for each completion instead of requiring repeated `--name` flags.
Usage looks something like
installShellCompletion --cmd foobar \
--bash <($out/bin/foobar --bash-completion) \
--fish <($out/bin/foobar --fish-completion) \
--zsh <($out/bin/foobar --zsh-completion)
Fixes#83284
This is a new package that provides a shell hook to make it easy to
declare manpages and shell completions in a manner that doesn't require
remembering where to actually install them. Basic usage looks like
{ stdenv, installShellFiles, ... }:
stdenv.mkDerivation {
# ...
nativeBuildInputs = [ installShellFiles ];
postInstall = ''
installManPage doc/foobar.1
installShellCompletion --bash share/completions/foobar.bash
installShellCompletion --fish share/completions/foobar.fish
installShellCompletion --zsh share/completions/_foobar
'';
# ...
}
See source comments for more details on the functions.
