Address Book in Aerc With Khard
In line with the Unix philosophy, Aerc does not implement any feature to store mail addresses of contacts. Instead it has an option to retrieve them from an external address book. I already synced my contacts together with my calendar items through Vdirsyncer and Radicale, but this was more for backup purposes. My phone does not play nice with any CardDav server.
But with Khard I can put the address book to good use. Khard is a command line program for contacts that understands the CardDav format. To configure Aerc to use Khard for mail address completion, look up the line in
aerc.conf that starts with
address-book-cmd= and fill it in like this to make it usable for Aerc:
address-book-cmd=khard email --parsable --search-in-source-files --remove-first-line %s
--parsable lets it return a tab delimited line as required.
--search-in-source-files makes it faster with large address books.
--remove-first-line removes the “searching for…” line in the response. Appearantly this line is required for Mutt, but it is not for Aerc.
I just installed Khard through apt and copy/pasted the default configuration that is provided in the docs. If you do so and you run
khard, you’ll be greeted by this error message:
$ khard Traceback (most recent call last): File "/usr/bin/khard", line 11, in <module> load_entry_point('khard==0.13.0', 'console_scripts', 'khard')() File "/usr/lib/python3/dist-packages/khard/khard.py", line 1753, in main args = parse_args(argv) File "/usr/lib/python3/dist-packages/khard/khard.py", line 1715, in parse_args config = Config(args.config) File "/usr/lib/python3/dist-packages/khard/config.py", line 74, in __init__ self.editor = find_executable(os.path.expanduser(self.editor)) File "/usr/lib/python3.7/posixpath.py", line 235, in expanduser path = os.fspath(path) TypeError: expected str, bytes or os.PathLike object, not list
The standard Debian version is probably too old and they probably changed the configuration options for the editor. The current format accepts a comma separated list with options, but the old one does not. Changing the editor option line in
editor = vim, -i, NONE
editor = nvim
lets everything work as intended.
