This greatly improves readability and makes it easier to discover options.
This commit was genereated by running the following script inside the
repo root dir:
#!/usr/bin/env ruby
def transform(src)
return false if src.include?('inherit options;')
success = false
options = nil
src.sub!(/^ options.*?^ }.*?;/m) do |match|
options = match
" inherit options;"
end
return false if !options
src.sub!(/^with lib;\s*let\n+/m) do |match|
success = true
<<~EOF
with lib;
let
#{options}
EOF
end
success
end
Dir['modules/**/*.nix'].each do |f|
src = File.read(f)
if transform(src)
puts "Changed file #{f}"
File.write(f, src)
end
end

# This module enables unprivileged users to read onion addresses.

# The included service copies onion addresses to /var/lib/onion-addresses/<user>/

This option controls who is allowed to access onion addresses.
|
|
For example, the following allows user 'myuser' to access bitcoind
|
|
and clightning onion addresses:
|
|
{
|
|
"myuser" = [ "bitcoind" "clightning" ];
|
|
};
|
|
The onion hostnames can then be read from
|
|
/var/lib/onion-addresses/myuser.

|
