add ability for clients to set mode/plugin automatically

[craftyguy]

I'm not sure if I described the title correctly, so feel free to edit if there's a better way to state this... but I would basically like to be able to run cosmic-launcher (which uses pop-launcher), and have it start up with some plugin of mine automatically selected so I can just start typing to filter the plugin's output.

For example, I have a plugin that runs my password manager. Today I have to hit some key binding to run cosmic-launcher, then I have to type some key/word to start the query for the password manager plugin and hit space, THEN I can start trying to select the password entry I want. The flow today is something like:

1. <super>D to start cosmic launcher
2. bw<space> to start the "bw" plugin in pop-launcher that I want
3. then I can start trying to find the thing I want

Ideally I could just have a key binding that runs cosmic-launcher in some way and have it show the pop-launcher plugin I want so I could skip the query/keyword step entirely and just start trying to select the password entry from the plugin. It would be nice if the flow was like:

1. <super>P (or whatever) to start cosmic-launcher --mode bw
2. then I can start trying to find the thing I want

I am currently hacking around this by creating a script like this, and then setting a custom keybinding to run it:

#!/bin/sh
cosmic-launcher &

# type the given keyword for pop-launcher to load the plugin I want
wtype "$1 " 

wait

Binding example for cosmic-launcher:

{
    (
        modifiers: [
            Super,
        ],
        key: "e",
        description: Some("Get emoji"),
    ): Spawn("~/bin/pop-launcher-auto-plugin emoji"),
...
}
