tools/cfgdump.lua @ 11192:11f285a439a4

tools/cfgdump: Reads Prosody config file and pretty-prints it back out Useful for comparing what you think you have in your config with what Prosody sees, e.g. wrt (lack of) significance of indentation, order of options vs scope etc. (global options do not go at the end!) Could probably be turned into a prosodyctl command, especially if it learns to redact secrets and passwords.
