From d81021ed265e3cdfe32cdd0082b139f796ff5bfa Mon Sep 17 00:00:00 2001 From: Paul Holzinger Date: Wed, 21 Apr 2021 11:32:03 +0200 Subject: Add go template shell completion for --format The --format flags accepts go template strings. I use this often but I consistently forget the field names. This commit adds a way to provide shell completion for the --format flag. It works by automatically receiving the field names with the reflect package from the given struct. This requires almost no maintenance since this ensures that we always use the correct field names. This also works for nested structs. ``` $ podman ps --format "{{.P" {{.Pid}} {{.PIDNS}} {{.Pod}} {{.PodName}} {{.Ports}} ``` NOTE: This only works when you use quotes otherwise the shell does not provide completions. Also this does not work for fish at the moment.
