Subject: busctl: add introspect --xml-interface
X-Git-Tag: v243-rc1~531^2~3
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d5c8d8233c2efbbd1e600d1a683ea04cd36cbac8;p=thirdparty%2Fsystemd.git

busctl: add introspect --xml-interface

This wraps the call to org.freedesktop.DBus.Introspectable.Introspect.
Using "busctl call" directly is inconvenient because busctl escapes the
string before printing.

Example:
$ busctl introspect --xml org.freedesktop.systemd1 /org/freedesktop/systemd1 | pygmentize -lxml | less -RF
